Disconnect the power from the machine before performing any maintenance or repair work. Turn power switch to the OFF position when changing tooling.7. Always disconnect from the power source before moving. Be sure switches are off before connecting to a power source.8. Magnet will not hold properly on thin materials (under 3/8") or rough and dirty surfaces.9. Always use safety chain and chip shield provided with machine. Never attempt to remove chips while cutter is in motion.10. Assure all tooling is properly held in position before starting any operation. Periodically check all tooling for tightness.11. Do not use dull or broken cutters.12. Keep tools sharp and clean for better and safer performance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if damaged, have repaired by authorized service facility. Inspect extension cords periodically and replace if damaged. Keep handles dry, clean and free from oil and grease.13. Beware of slugs ejected at end of cut. They become HOT during the cut.14. Keep bottom of magnet burr free and clear of chips and debris.15. Avoid operating drill at greater than 45 degree angle. Overhead drilling is extremely hazardous and is not recommended.16. Drilling stacked material requires a special STACKED GEOMETRY cutter.Auto AutoGeneral InformationThe Cleveland Steel Tool Handy-Mag III is a lightweight, compact drilling system that features:• Manual capacity up to 1-3/8" diameter through 2"” materialAutomatic capacity 1-1/4" through 2"” material*Drilling stacked material requires a special STACKED GEOMETRY cutter. • Positive slug ejection system• Internal cutter lubrication for increased tool life• Powerful motor with cast aluminum housing• Adjustable motor slide ways• Complete coolant system• Safety Chain• Chip shield• Rugged carrying caseSPECIFICATIONS:• Annular cutter range: 7/16” thru 1-3/8”• Annular cutter depth range: 0-2”• Weight: 38 lbs.• Height: 17”• Voltage: 110v AC only, 10 amps, 1200 watts, earth ground & double insulation • Frequency: 50-60 HZ• RPM No Load: 550 RPM• Magnetic Holding Deadlift: 3500 lbs.• Magnet dimensions: 8” x 3” footprintAutoWarning:Improperly connecting the grounding wire can result in the risk of electrical shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly ground-ed. Do not modify the plug provided with tool. Never remove the grounding prong from the plug. Do not use tool if the cord or plug is damaged. Have it repaired before using. If the plug will not fit the outlet, have a proper outlet installed bya qualified electrician. The Handy-Mag III must be pluggedAutointo an appropriate outlet, properly installed and groundedin accordance with all codes and ordinances. The rigid ear or lug extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box orreceptacle. Simply remove the center screw from the outlet,insert the adapter and reattach the screw through the green grounding ear to the outlet. If in doubt of proper grounding, call a qualified electrician.Extension CordsUse only 3-wire extension cords that have 3-prong ground-ing type plugs and 3-pole receptacles that accept the tool’s plug. Replace or repair damaged cords. Make sure your extension cord is in good condition. When using an exten-sion cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheat-ing. See table for the correct size to use depending on cord length and nameplate amperage rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavi-er the cord.Drip Loop: To help prevent fluids from travel-ing the power cord and contacting the powersource, tie a drip loop in the power cord.Getting StartedYour Handy-Mag III package should contain the following parts:QTY Part# Description1 Handy-Mag III1 Carrying Case1 Owners Manual1 ME3017 Coolant elbow connector1 ME3041 Retaining Knob M5x161 ME3042 Coolant Tank1 ME3044 Coolant PU Tube3 ME3062 Crank Spindle1 ME3077 Combination Wrench M81 ME3078 Hex Wrench M2.51 ME3079 Hex Wrench M41 ME3082 Safety Guard 1 ME3083 Safety ChainAssemble 3 crank spindles (ME 3062) to the crank hub (ME3100). The crank hub is mounted on the right side of the machine frame. Attach the coolant tube (ME3044) to the coolant tank (ME3042) using screw (ME3041). Attach coolant tube (ME3044) to coolant elbow connector (ME3017).What You Need To KnowType of material to be drilled, Brinell or Rockwell hardness, material thickness and position should all be determined to ensure proper selection of Handy-Mag III cutting tools, RPM, coolant and drilling time.Remove any excessive mill scale or rust from the surface to be drilled.When drilling materials under 3/8" thick, an additional steel plate may be required to achieve proper magnetic adhesion.Drilling stacked material requires a special STACKED GEOMETRY cutter.Material that has been flame cut may have become heat treated and therefore difficult to drill. Avoid drilling near such areas whenever possible.Drilling with the Handy-Mag III in horizontal positions requires a special lubrication for Handy-Mag III cutters. Consult The Cleveland Steel Tool Co. for details.Auto Auto Auto Auto AutoBefore the Cut1. Select the correct pilot pin and place it in the cutter shank from the rear.Align the flats on the cutter shank with the arbor body set screws.Insert cutter shank into the arbor body.2. Tighten the set screws securely on the cutter shank flats. Note: The set screws should be recessed in the arbor body when tight.3. Place the Handy-Mag III machine on work piece with pilot pin over the center of hole to be drilled.4. Connect machine to power source.5. Lower Handy-Mag III cutter to surface of material to be cut. Fill coolant tank with a water solublecoolant. Open coolant tap (ME3043) to release coolant.Note:Coolant flow starts when pilot pin contacts work surface. Coolant flow can be stopped by lifting pin off work surface.6. Safety chain must be securely fastened to machine and around the work being drilled.Note: Safety chain is intended only to secure drill to work piece in case of emergency, such as a loss of power to the magnetic base.7. Attach chip shield (ME3082) to machine with butterfly screws (ME3081) and washers. Caution!Do not use the Handy-Mag III for work other than it’s intended use.The Handy-Mag III is designed to work only with the tooling e of other tooling may cause damage to the drill, cause personal injury and void the warranty. CAUTION: Always use safety chain. Failure to do so could result in personalinjury and/or damage to theHandy-Mag III drilling machine.⇨Auto Auto Auto Auto AutoMaking the Cut CAUTION: Always use chip shield.1. Move magnet switch to “On” position, panel lamp should illuminate indicatingpower is on. Magnetic base should be firmly secured to work piece at this time.2. Start drill motor by depressing green motor “On” button.3. Using the feed handles, advance cutter into material until Handy-Mag cutter hasestablished an external groove in the material, during the remainder of cut apply,smooth constant pressure without overloading motor.NOTE: Handy-Mag cutters are designed for uninterruptedcutting, chips are evacuated during the cut. Do notpeck drill when using Handy-Mag cutters.CAUTION: If drill motor should stall or stop before a complete cut is made, always shut the motor off and remove the cutter from the hole before attempt-ing to restart the motor. Failure to do so could result in personal injury and/or damage to the Handy-Mag III drilling machine or cutter.After the Cut 1. After the Handy-Mag III cutter has finished the cut, the “slug” or uncut centerportion of material will be expelled when motor is returned to the full up position.Beware of slugs ejected at end of cut. They become HOT during the cut.2. Return the machine to a full upright position and depress red motor “OFF “button. Wait until motor completely stops.3. Move magnet switch to “OFF” position when ready to release magnetic basefrom work surface.Auto AutoOperating Auto-Feed FeatureThe Handy-Mag III can be used as a manual machine when the three feed handles are pointed out.AutoTo switch to automatic drilling:1. Begin drilling manually with the handles pointed out.2. After the cutter has begun cutting, push the feed handles in parallel with the side of the machine.Note: The gears may not always line up perfectly. If the handles will not push in, simply raise the feed upward slightly and the handles will engage.3. Once in auto-feed and throughout the drilling process, always keep a hand firmly on the side handle to stabilize the machine.4. As a precaution, always keep the other hand near the motor shut off switch in the event of a problem.5. Once the hole is drilled, the machine will expel the slug and stop.Situations Where The Safety OverrideSystems Will Automatically Engage1. When there is a sharp decrease in load, such as when the hole is finished or if a cutter breaks, the feed will automatically return to the top and stop. The magnet will remain on.2. If the chip load exceeds maximum for 2 seconds, the motor and feed will stop and stay in that position. Only the magnet will stay on. This will alert the operator of an overload problem. If this hap-pens repeatedly, it may be an indication of a worn cutter or other problem.3. If the feed reaches the bottom of its stroke, it will automatically return. This will happen if the ma-chine is operating under zero load (test conditions) if attempting to drill past the maximum depth of a 2" depth cutter.9Maintenance1. Adjusting motor slide tension:The motor slide assembly may become loose and require adjustment after the machine has been in service. Wrenches are provided in the tool kit for performing adjustments. • Using the feed handles, position motor and slide assembly in the full up position. • Loosen 6 jam nuts (ME3048) and equally tighten 6 adjustment screws (ME3047) using 2.5mm and 8mm combination wrench and hex key. • Do not over tighten adjustment screws. Excessive slide tension can damage the machine. Properly adjusted, the motor/slide assembly should have no side to side movement and remain positioned without drifting down.2. Inspecting magnet base:Keep bottom of magnet clean, free of chips, burrs, nicks, oil and other contaminants. Inspect magnet face to insure surface is flat and square. A worn magnet surface dramatically reduces magnetic holding force.3. Lubricating motor slideways:Periodically clean and lubricate motor slide ways with lithium base grease.4. Inspecting arbor support system:Visually inspect arbor, sleeve and support bracket for wear.Caution: Always remove cutter from arbor body before measuring runout, never use hands or fingers to rotate arbor or motor spindle.5. Checking arbor runout:Arbor runout should not exceed .0035 per revolution. This is most accurately measured by placing a dial indicator needle inside of arbor bore and rotating arbor while observing indicator.6. Motor brush inspection:Inspect motor brushes and replace as needed during extended periods of heavy machine usage.CAUTION: Never operate machine with worn or missing parts.10Troubleshooting1. Magnetic base is not holding securely:• Material being drilled must be a minimum of 3/8" thick for proper magnetic adhesion. • Surface of material should be free of chips, debris, rust and mill scale. • Verify size of cutter. It should not exceed machines capacity. • Check magnet face for unevenness, nicks and burrs. • Welding equipment should not be connected to material being drilled.2. Drill motor is running, arbor and spindle is not turning: • Spindle key (HM3006) could be sheared.3. Motor slows when drilling: • Check extension cord requirements if one is being used. (pg. 4) • Excessive downfeed pressure during drilling cycle will cause motor to slow and overheat. • The cutting tool may need to be resharpened.4. Coolant system not working: • Coolant system is gravity dependent. Machine must be in an upright position to operate properly. • Consistency of coolant mixture is too thick. • Check for the correct pilot pin.5. Slugs not ejecting from cutter: • Lack of coolant can cause slugs to expand in cutter bore. • Check for correct pilot pin. • Check for broken internal arbor parts. * Drilling stacked material requires a special STACKED GEOMETRY cutter.6. Breaking cutters: • Coolant must be applied to the interior of the cutter. • Excessive downfeed pressure when cutter contacts work surface can cause breaks. • Confirm material hardness. • Drilling stacked material with improper cutter. (Drilling stacked material requires special cutters) • Dull cutters and dull or chipped cutting edges require excessive feed pressure resulting in breakage. • Excessive arbor runout. (see pg.9 for maintenance) • Motor spindle is bent or there is a worn arbor sleeve. • Motor slide is improperly adjusted. (see pg.9)7. Oversized or rough holes: • Insufficient coolant. • Excessive feed pressure. • Dull cutter. • Worn support bracket roller bearing or arbor body sleeve. • Bent motor spindle. • Motor slide improperly adjusted.11Parts ListItem DescriptionPart No. Qty Req.1 Set Screw M5 x 6 ME3001 52 Cutter Arbor Complete (inc 125-132) ME3002 13 Water Seal ME3003 14 Spring ME3004 1 `5 Main Drive Spindle ME3005 16 Woodruff Key M5x5x10 ME3006 17 Oil Seal 22x32x7 ME3007 28 Gearbox Case ME3008 19 Bearing 6003zz ME3009 2 10 Snap Ring R-35 ME3010 1 11 Circlip S-17 ME3011 1 12 Final Drive Gear 52T ME3012 1 13 Circlip S-14 ME3013 1 14 Bearing 608zz ME3014 4 15 Gear Pinion 8T ME3015 1 16 1st Drive Gear 50T ME3016 1 17 Coolant Elbow Connector ME3017 1 18 Inter Gear Plate ME3018 1 19 Fan Shroud ME3019 1 20 Bearing 609zz ME3020 1 21 Armature 110V ME3021 1 22 Screw M5x55 ME3022 2 23 Field Assy 110V ME3023 1 24 Motor Housing ME3024 1 25 Brush Holder ME3025 2 26 Carbon Brush Set ME3026 2 27 Brush Cap ME3027 2 28 Hex Head Bolt M5x40 ME3028 4 29 Spring Washer M5 ME3029 8 31 Motor Cord ME3031 1 32 Cord Armour ME3032 1 33 Cord Clip ME3033 2 34 Pan Head Screw M4x16 ME3034 2 35 Wire Connector C4 ME3035 2 36 Gear Rack ME3036 1 37 Main Slide Plate ME3037 1 38 Hex Head Bolt M6x20 ME3038 512Parts ListItemDescription Part No. Qty Req. 39 Coolant Tank Hanger ME3039 1 40 Flat Washer 3/16x16x1 ME3040 2 41 Retaining Knob M5x16 ME3041 142 Coolant Tank ME3042 1 43 Coolant Tap ME3043 1 44 Coolant PU Tube ME3044 1 45 Conduit Gland ME3045 1 46 Main Body Assy ME3046 1 47 Set Screw M5x20 ME3047 8 48 Nut M5 ME3048 8 49 Brass Slide Right ME3049 1 50 Steel Strip Tensioner ME3050 1 51 Brass Slide Left ME3051 1 52 Electro-Magnet Switch ME3052 1 53 Motor Switch Button On ME3053 1 54 Bushing ME3054 2 55 Motor Switch Button Off ME3055 1 56 Front Switch Panel ME3056 1 57 Screw M4x16 ME3057 4 58 Selector Cam ME3058 1 59 Screw & Washer ME3059 1 60 Switch Plate Bar Short ME3060 2 61 Engagement Ball M5 ME3061 8 62 Crank Spindle ME3062 1 63 Handle Grip ME3063 3 64 Rear Cover Plate ME3064 1 65 Screw M3.5x6 ME3065 4 66 Pan Head Screw M4x8 ME3066 7 67 Stroke Limiting Switch ME3067 1 68 Electronic Unit 110V ME3068 1 69 Star Washer M4 ME3069 1 70 Power Cord ME3070 1 71 Pan Head Screw M4x6 ME3071 1 72 Electro-Magnet ME3072 1 73 Arbor Support Bracket ME3073 1 74 Arbor Support Bearing HK3516 M E3074 1 75 Spring Washer M8 ME3075 3 76 Hex Head Screw M8 ME3076 3 77 Combination Wrench M8 ME3077 1 78 Hex Wrench M2.5 ME3078 1Parts ListItem Description79 Hex Wrench M4 ME3079 1 80 Washer M6x13x1 ME3080 2 81 Butterfly Screw M6x10 ME3081 2 82 Safety Guard ME3082 1 83 Safety Chain ME3083 1 84 Pan Head Screw M4x12 ME3084 1 85 Flatwasher M4 ME3085 5 86 Cover Plate ME3086 1 87 Hex Head Screw M8x16 ME3087 4 88 Cord Protector ME3088 1 89 Flat Washer M8x20x1 ME3089 2 90 Hex Head Screw M10x30 V1 ME3090 1 91 Spring Washer M10 V1 ME3091 1 92 Flat Washer M10x23x2 V1 ME3092 1 93 Motor Mounting Plate V1 ME3093 1 94 Hanger ME3094 1 95 Crank Handle ME3095 3 96 Pan Head Screw M5x8 ME3096 1 97 Crank Lever Tip ME3097 3 98 Hub Cover ME3098 1 99 Spring Pin 4.2x25 ME3099 3 100 Crank Hub ME3100 1 101 Selector Rod ME3101 1 102 Auto Feed Motor Unit 110v M E3102 1 103 Feed Motor Gear Box Unit ME3103 1 104 Feed Support Plate ME3104 1 105 Flat Head Screw M5x15 ME3105 4 106 Flat Head Screw M5x45 ME3106 4 107 Ball Bearing 6809zz ME3107 1 108 Gear 63T ME3108 1 109 Auto Feed Side Cover ME3109 1 110 Hex Head Screw M5x10 ME3110 5 111 C-Clip C-28 ME3111 1 112 Bushing 8x12x6 ME3112 2 113 Output Gear 80T ME3113 1 114 Woodruff Key 4x4x10 ME3114 1 115 Gear Pinion 12T ME3115 1 116Screw M4x25 ME3116 214Parts ListItem Description Part No. Qty Req.117 Cord Protector ME3117 1118 Hex Nut M4x8 ME3118 2 119 Hex NutME3119 1 120 Flat Washer 1/2x24x2.5 ME3120 1 121 O-Ring 7.5x1.5ME3121 1 122 Limit Switch Pin 2.2x10 ME3122 2 123 Set Screw M8x8 ME3123 3 124 Capacitor ME3124 1 125 Circlip ME3125 1 126 CollarME3126 1 127 Return SpringME3127 1 128 Spring Retainer Ring ME3128 1 129 Set Screw M3x12 ME3129 1 130 Lock Pin ME3130 1 131 Screw M3x6 ME3131 1 132 Flat SpringME3132 1 133 Hex Bolt M8x60 ME3133 1 134 Screw M4x10 ME3134 2P a r t s B r e a k d o wnH a n d y -M a g I I IA u t o。
Tigertriever 13产品说明书
expandable stentretriever,the Tigertriever13(Rapid Medical, Yoqneam,Israel).Here,the stentretriever is not unsheathed but pushed out of the microcatheter,advanced as far as possi-ble before manual opening.This technique may be used in2 different situations.First,in case of vessel tortuosity if the microcatheter can’t be advanced as far as the physician wants: the Tigertriever13can be delivered through the microcatheter without having to unsheathe it,be advanced and opened dis-tally to its microcatheter to establish a stable anchor prior to advancing the guiding,intermediate and micro-catheters (anchor technique).The second situation is when distal occlu-sions lead to length issues,the microcatheter may be too short to cross a distal clot:the Tigertriever13can then be pushed out of the microcatheter,and be used to cross a sub-occlusive clot as it has a soft shaped distal tip and the physician sees the artery beyond the sub-occlusion.Then,the Tigertriever will be manually expanded through the clot,and retrieved (harpoon technique)to obtain a recanalization.Disclosures A.Guenego:None.B.Lubicz:None.E-035INTRA-ARTERIAL TISSUE PLASMINOGEN ACTIVATOR (IA-TPA)AS FIRST LINE AND SALVAGE THERAPY TOACHIEVE COMPLETE REPERFUSION IN ACUTE ISCHEMICSTROKEM Waqas,S Housley,A Baig,J Cappuzzo,A Monteiro,W Khawar,E Levy,A Siddiqui. Neurosurgery,University at Buffalo,Buffalo,NY10.1136/neurintsurg-2022-SNIS.146Introduction Despite advances in neurointervention with better mechanical thrombectomy devices and more sophisticated tech-niques,unsuccessful reperfusion(TICI0–1)remains the end-result in1out of every10patients,with most patients who are successfully treated not attaining neurologic independence at90-days.This is true especially for tough-to-remove clots. We aim to investigate the potential role of intra-arterial tissue plasminogen activator(IA-tPA),as both first-line and salvage therapy after failed completed reperfusion.Methods A prospectively maintained database was retrospec-tively searched for acute ischemic stroke patients treated with IA-tPA as either first-line technique or as salvage therapy fol-lowing failed mechanical thrombectomy(aspiration,stent-retriever,or both)from Jan2010to Jan2022.Patient demo-graphics,comorbidities,presenting NIHSS,IV-tPA,and IA-tPA administration were recorded.Other procedural details such as total no.of passes,first pass effect,and intra-and post-op complications were also recorded.Outcomes were measured in terms of symptomatic intracerebral hemorrhage(sICH),dis-charge NIHSS,and mRS at90-days.Results Forty patients were included in our study(23female; mean age68.1±13.7years).Hypertension was the most com-mon comorbidity in26cases(65%),followed by hyperlipide-mia in22(55%).Femoral artery was used as site of access in 36cases(90%)with radial artery being used in4(10%). Median presenting NIHSS was12(Range:5–27)and IV-tPA was administered in12cases(30%).IA-tPA was used as first-line therapy for22cases(55%),and as salvage therapy in addition to Aspiration in7(17.5),with stent-retriever in3 (7.5%),and with both in8cases(20%).First pass effect (mTICI2B-3)was achieved in16cases(40%),and a final mTICI of2B-3attained in27total cases(67.5%).In terms of intraoperative complications,clot migration was seen in2cases(5%)and dissection in3(7.5%).sICH(defined as parenchymal hematoma type II)was seen in6cases(15%).

Further,we discuss genetic drivers of this condition,and pro-vide example cases of select imaging findings.Results Our review identified several studies reporting the population prevalence of moyamoya.This included:16.1/ 100,000in Korean populations, 3.2–10.5/100,000in Japa-nese populations, 3.9/100,000in Chinese populations, 1.6/ 100,000in Taiwanese populations,and0.8/100,000in Euro-pean populations.The prevalence of moyamoya in patients with Neurofibromatosis1is600/100,000,and is3800/ 100,000in patients with Trisomy21.The increased preva-lence of moyamoya in East Asian populations reflects the prevalence of the RNF213gene,which causes familial moya-moya disease.In non-East Asian populations,the recently-identified DIAPH1gene is a risk factor for sporadic moya-moya disease.Conclusions Given the number of available risk factors for moyamoya vasculopathy,clinicians have the ability to screenfor this condition and minimize its clinical impact.Disclosures uzier:None.K.Guilliams:None.A.Kansa-gra:None.E-037WHAT STROKE PATIENTS POST ONLINE ABOUT:ANINSTAGRAM AND TWITTER ANALYSIS1A Gajjar,1A Jain,1A Dinh Le,1M Salem,2S Hasan,1B Jankowitz,1J Burkhardt.1Neurosurgery,University of Pennsylvania,Philadelphia,PA;2University of Pennsylvania, Philadelphia,PA10.1136/neurintsurg-2022-SNIS.148Introduction Increased social media usage has allowed many individuals and patients to connect and influence their patient population through providing their own opinions and health experiences.Conducting patient feedback surveys serves as a valuable means for obtaining important information about patients’sense of satisfaction regarding their outcomes,and perioperative needs.In this study,to better understand the patient experience after stroke,the authors sought to assess patient-managed,provider-independent T witter and Instagramposts on social media to further understand the patient per-ception of stroke.Methods A variety of terms(‘stroke’,‘stroke survivor’,‘stroke rehab’,‘stroke recovery’)were used to search for potentially relevant hashtags to find possible qualified posts on T witterand Instagram.Four hundred sixty-eight public Instagramposts marked under‘#stroke’and‘@stroke’including direct references to the patient‘s own experience were analyzed (June2018to July2021).T witter posts containing‘#stroke’and‘@stroke’were identified,and the search resultsyielded Abstract E-036Figure1on December 24, 2023 by guest.

左臂壳体设计说明书
大学00学院本科生毕业论文（设计）题目左臂壳体加工毕业设计学院000000000专业班级0000学生姓名0000指导教师0000撰写日期：2014年00月00日中文摘要零件的加工工艺编制，在机械加工中占有非常重要的地位，零件工艺编制得合不合理，这直接关系到零件最终能否达到质量要求；夹具的设计也是不可缺少的一部分，它关系到能否提高其加工效率的问题。
因此这两者在机械加工行业中是至关重要的环节。
左臂壳体零件的主要加工表面为孔和外圆表面。
外圆表面加工根据精度要要求可选择车削和磨削。
孔加工方法的选择比较复杂，需要考虑零件的结构特点、孔径大小、长径比、精度和粗糙度要求以及生产规模等各种因素。
对于精度要求较高的孔往往还要采用几种不同的方法顺次进行加工。
本次设计的连接套，为保证孔的精度和表面质量将先后经过粗车、半精车、精车和钻孔、铰丝等工序加工。
在机床上对零件进行机械加工时，为保证工件加工精度，首先要保证工件在机床上占有正确的位置，然后通过夹紧机构使工件在正确位置上固定不动，这一任务就是由机床夹具完成。
对于单件、小批量生产，应尽量使用通用夹具，这样可以降低工件的生产成本。
但是由于通用夹具适用各种工件的装夹，所以夹紧时往往比较费时间，并且操作复杂，生产效率低，也难以保证加工精度，为此需设计专用夹具。

Therefore this both in the machine-finishing profession are the important links.Sleeve components main processing surface for hole and outer annulus surface. The outer annulus face work needs to request according to the precision to be possible to choose the turning and the grinding. The hole processing method's choice is quite complex, needs to consider the components the unique feature, the aperture size, the length to diameter ratio, the precision and roughness request as well as the scale of production and so on each kind of factor. Often must use several different methods regarding the accuracy requirement high hole to carry on the processing in order. This design's cylinder, will pass through half finished boring, the finished boring, the fine articulation and the trundle successively for the guarantee hole's precision and the surface quality and so on five working procedure processingsWhen the engine bed carries on the machine-finishing to the components, is guaranteed that the work piece working accuracy, first needs to guarantee the work piece holds the correct position on the engine bed, then causes the work piece in the correct position through the clamp organization fixed motionless, this duty is completes by the engine bed jig. Regarding the single unit, the small batch production, should use the universal jig as far as possible, like this may reduce the work piece the production cost. But because the universal jig is suitable each kind of work piece the attire to clamp, therefore time clamp often compares spends the time, and operates complex, the production efficiency is low, also guarantees the working accuracy with difficulty, for this reason must design the unit clamp.Key word: Craft, datum, cutting specifications, localization datum, position error.目录第一章零件的分析 (1)1.1左臂壳体的作用 (1)1.2左臂壳体的主要工艺分析 (1)第二章左臂壳体工艺规程设计 (2)2.1确定毛坯尺寸和毛坯图 (2)2.2基准选择 (2)2.2.1粗基准的选择 (2)2.2.2精基准的选择 (2)2.3表面加工方法的选择 (2)2.4制定工艺路线 (3)2.5工艺方案的比较与分析 (5)2.6加工余量和工序尺寸 (5)2.7各种机床与刀具选择 (7)2.8确定切削用量和基本工时 (7)2.8.1加工条件 (7)2.8.2计算切削用量 (8)2.9计算时间定额和提高生产率的工艺途径简介 (21)第三章夹具设计 (22)1零件专用夹具的设计 (22)1.1 机床夹具介绍 (22)1.2 现代夹具的发展发向 (23)1.３机床夹具的定位及夹紧 (25)1.4 机床夹具在机械加工中的作用 (28)1.5工件的装夹方式 (29)1.6 基准及其分类 (30)1.7 工件的定位 (31)1.8 常见定位方式及定位元件 (32)1.9工件的夹紧 (33)2问题的提出 (36)3车床夹具设计 (37)3.1定位基准的选择 (37)3.2 定位误差分析 (37)3.3 夹具设计及操作的简要说明 (37)3.4 夹具零件 (37)第四章结论 (42)致谢 (43)参考文献 (44)第一章零件的分析1.1左臂壳体的作用左臂壳体：主要用来联接齿轮变速箱和旋耕机刀架支臂及链条传动箱，共同组成旋耕机支架。

机械手臂说明书
1、手臂的设计2.1、手臂伸缩的设计计算手臂是机械手的主要执行部件。
它的作用是支撑腕部和手部，并带动它们在空间运动。
臂部运动的目的，一般是把手部送达空间运动范围内的任意点上，从臂部的受力情况看，它在工作中即直接承受着腕部、手部和工件的动、静载荷，而且自身运动又较多，故受力较复杂。
根据液压缸运动时所需克服的摩擦、回油背压及惯性等几个方面的限力，来确定液压缸所需的驱动力。
手臂的伸缩速度为250mm/s行程L=300mm液压缸活塞的驱动力的计算P = P摩■ F密■ F回■ F惯式中P摩一一摩擦阻力。
手臂运动时，为运动件表面间的摩擦阻力。
若是导向装置，则为活塞和缸壁等处的摩擦阻力。
P密一一密封装置处的康擦阻力；P回一一液压缸回油腔低压油掖所造成的阻力；P惯一一起动或制动时，活塞杆所受平均惯性力。
p摩、P密、P回、％的计算如下。
2.1.1、P摩的计算不同的配置和不同的导向截面形状，其摩擦阻力不同，要根据具体情况进行估算。
图4-15为双导向杆导向，其导向杆截面形状为圆柱面，导向杆对称配置在伸缩缸的两侧，启动时，导向装置的摩擦阻力较大，计算如下：由于导向杆对称配置，两导向杆受力均衡，可按一个导向杆计算。

1.2 零件工艺分析通过对该零件的重新绘制，知道原图样的视图基本正确，完整尺寸，公差及技术要求齐全。
但左右两端的加工精度较高。
要进行精加工才能达到要求。
该零件属于轴类回转体零件，它的中间部分是直接铸造出来的，无需加工。
精加工可以保证跳动及粗糙度要求，在车床上一次装夹同时车Φ80外圆及镗Φ52内孔可以保证同轴度要求，左右两组4*Φ13的孔在钻床上用钻套加工保证位置度，Φ8F9049.0013.0++和Φ8N8003.0-025.0-的孔，精度要求高，需要钻加工后铰，位置可以采用专用钻套来保证。
1.3零件的生产类型依设计题目知：Q=3000台/年，n=2件/台；结合生产实际，备品率α和废品率β分别取为10%和1%。
带入公式得该零件的生产纲领 N=3000×2×（1+10%）×（1+1%）=6666件/年零件是轻型零件，根据《机械制造技术基础课程设计指南》表2-1可知生产类型为大批生产。
第二章毛坯的选择和设计2.1 选择毛坯及毛坯热处理由于零件的材料为HT200，并且零件结构相对较为复杂，因此采用铸造。
从提高生产率，保证加工精度上考虑，也是应该的。
毛坯的热处理：灰铸铁（HT200）中的碳全部或大部分以片状石墨方式存在铸铁中，由于片状石墨对基体的割裂作用大，引起应力集中也大；因此，使石墨片得到细化，并改善石墨片的分布，可提高铸铁的性能。
可采用石墨化退火，来消除铸铁表层和壁厚较薄的部位可能出现的白口组织（有大量的渗碳体出现），以便于切削加工。
2.2 确定机械加工余量、毛坯尺寸由《铸件尺寸公差与机械加工余量（摘自GB/T 6414-1999）》确定：（1）求最大轮廓尺寸由零件图计算轮廓尺寸，长243mm，宽115mm，高155mm，故最大轮廓尺寸为243mm。
（2）选取公差等级IT查表得，铸造方法按金属型铸造、铸件材料按灰铸铁，得公差IT范围8-10级，取为9级。
（3）求铸件尺寸公差根据加工面的基本尺寸及铸件公差等级IT ，查表得，公差相对基本尺寸对称分布。
（4）求机械加工余量等级查表得，铸造方法按机械造型、铸件材料按灰铸铁，得机械加工余量等级范围D-F 级，取为E 级。
（5）求RAM对所有加工表面取同一数值，查表得，最大轮廓尺寸为243mm ，机械加工等级为E 级，得RAM 为1.4mm 。
（6）求毛坯尺寸Φ80外圆及Φ72外圆台阶较小宜不铸出。
两组4*Φ13mm ，Φ8N8mm 孔，Φ8F9mm 孔铰小，铸成实心。
Φ5204.001.0++的孔属内腔加工，得R=F-2RAM-CT/2=52-2.8-2.8/2=47.8mm为了铸造简单，与Φ45的孔铸成一样大小，故取直径为Φ45mm. 长度方向为了铸造方便，不再铸造台阶，故长度方向取为243mm.2.3 确定毛坯尺寸综上所述，确定毛坯尺寸见表2-1表2-1 左臂壳体毛坯（铸件）尺寸2.4 设计毛坯图（附件一）第三章工艺路线的拟定3.1 定位基准的选择本零件是带孔的柱状零件，孔是其设计基准（亦是装配基准和测量基准），为避免由于基准不重合而产生的误差，应选孔为定位基准，即遵循“基准重合”的原则。
具体而言，即选Φ80孔和右端面为精基准。
以左端面作为粗基准。
3.2 零件表面加工方法的选择本零件的加工面有外圆，内孔，端面，钻孔等，材料为HT200。
以公差等级和表面粗糙度要求，参考有关资料，其加工方法选择如下：（1）Φ80mm外圆面，公差等级为IT7，表面粗糙度为Ra6.3um，径向跳动公差为0.04mm,需要粗车，半精车，精车。

（3）右端面的表面粗糙度为Ra6.3um，端面跳动公差为0.05mm，需要粗车，半精车，精车。
（4）Φ72mm外圆面，公差等级为IT8，表面粗糙度为Ra6.3um，径向跳动公差为0.04mm，需要粗车，半精车，精车。
（5）左端面的表面粗糙度为Ra6.3um，端面跳动公差为0.05mm，需要粗车，半精车，精车。
（6）左右1mm的台阶，未注尺寸公差，公差等级按IT14，表面粗糙度为Ra25um，粗车即可。

5.1.1设计任务本次设计是对左臂壳体左面的4*Φ13的孔加工的钻床夹具设计。
5.1.2设计目的（1）让学生能够熟练的运用机械制造工艺学的基本知识理论和夹具设计原理，培养学生分析和解决问题的能力。
（2）通过实践让学生学会理论联系实际，能够独立自主的解决机械加工中遇到的问题。
5.2零件的材料与结构分析零件的材料为HT200，铸造性能优良，但是塑性较差、脆性较高、不适合磨削，而且加工面主要集中在外圆加工和孔的加工。
根据对零件图的分析，该零件需要加工的表面以及加工表面之间的位置要求如下：（1）根据零件的总体加工特性，左端Φ115和右端Φ95的端面为整个机械加工过程中主要的基准面，因此在制定加工方案的时候应当首先将此面加工出来。
（2）左端Φ72和右端Φ80的端面没有技术要求，粗加工即可，而左端Φ72和右端Φ80的外圆要求其径向跳动为0.04-0.06之间，为了保证其径向跳动符合技术要求，先粗车左端Φ72的外圆，再粗车右端Φ80的外圆，然后精车左端Φ72外圆，再精车右端Φ80的外圆，为了保证Φ52孔和Φ80的外圆同轴度偏差不超过0.025，精车Φ80外圆后，直接粗、精Φ52孔就可以保证了。
