Remember that the wood work top is 1.25" thick, so you will need to reduce the leg length by the 1.25" to hit your targeted height. Make sure the length of each leg is the same.Insert one cross brace so that it can be fastened together with the adjustable leg section and main leg section at the desired height, making sure all holes are lined up. Use four (4) nuts and bolts to secure the cross brace. Repeat to connect a second leg, which creates one leg assembly.Secure the leg assembly with another cross brace at the top of the legs using four (4) bolts and nuts per leg.Tighten all nuts and bolts.Repeat to create the second leg assembly, which will form the other end of the workbench.Line up the holes in the two cross bars with the holes in the top of the leg assemblies. The cross bar flange will overlap the legs at each end. Secure each cross bar to the top of each leg using two (2) nuts and bolts.Connect the braces from the front cross bar to the leg assemblies to improve stability, using two (2) nuts and bolts for each brace.Do not tighten fasteners until all legs are connected to the cross bars and braces. Once all legs are connected, use a level to make sure the frame is straight, then tighten all nuts and bolts.Attach the bottom shelf to the bottom cross braces using two (2) nuts and bolts on either side. The shelf is recessed so that a stool can be tucked under the workbench.Place the work top on a soft mat with the finished top surface facing down.Place the steel frame upside down on the work top. The work top should be flush with the back of the frame – this would be the back of your workbench. It will allow the workbench to be pushed close to the wall and leave an overhang on the front of the workbench.Center the frame, right to left.Mark the holes on the steel frame onto the bottom of the work top. Remove the steelframe. Drill pilot holds in the bottom of the work top at the locations you have marked.Place the steel frame back on the work top and secure using the screws that areincluded. Six screws are used to attach the work top to each long cross bar and four screws are used to attach the work top to each short cross brace.Turn the workbench upright and place in the location it will be used. Check to make sure the workbench is still level. If you need to adjust, use the leveling feet.Attach the Montezuma Nameplate to the right hand side of the front cross bar using the self-adhesive backing.8Build the back wall onto the workbench by slipping a column onto one back corner of the work top. The column should be nested above and below the work top. Mark the location of the holes in the bottom of the column on the bottom of the work top. Remove the column and drill pilot holes in the bottom of the work top. Set the column back in place so the work top is nested into the column and secure the column in place using the four (4) lag screws. Repeat on the other side with the remaining column.Attach the top shelf by nesting it down in the tops of each of the columns. The columns have been designed with notches to help locate the top shelf into place. Fasten the top shelf to each of the columns using two (2) nuts and bolts in the side and back of the columns.Place the column cross brace under the top shelf and secure it to each column with one (1) nut and bolt. The cross brace is notched so it will set under the top shelf and the end of the cross brace will overlap the front of each column.On the back side of the workbench, lift the pegboard panel into place. Line up the holes of the pegboard panel with the holes in the inside edge of the columns. Secure with three (3) nuts and bolts. It may be easier to complete this step with one person inserting the bolts into the holes from the front and another person in back tightening the nut. Secure the top of the pegboard panel to the top shelf with two (2) nuts and bolts. Repeat this assembly with the other side of the pegboard panel.Carefully drill pilot holes in the top of the work top that line up with the holes in the bottom of the pegboard panel. Screw the bottom of the pegboard panel into place using lag screws. Check one more time to make sure your workbench and back wall are level. Secure all fasteners and move into place. Make sure it is level in the area it will be used.MAINTENANCEPeriodically tighten all hardware and make sure workbench is level.Clean the work top with wood cleaner.SAFETYDO NOT let children play or hang on the edge of the workbench. It could tip and cause personal injury or product damage.DO NOT stand or lean on the work top. The workbench could tip and cause personal injury or product damage.DO NOT mount this product on a truck bed or any other moving object.

超净工作台说明书
产品说明书超净工作台的优点是操作方便自如，比较舒适，工作效率高，预备时间短，开机30分钟以上即可操作，基本上可随时使用。
在工厂化生产中，接种工作量很大，需要经常长久地工作时，超净台是很理想的设备。
超净工作台由三相电机作鼓风动力，功率145～260W左右，将空气通过由特制的微孔泡沫塑料片层叠合组成的“超级滤清器”后吹送出来，形成连续不断的无尘无菌的超净空气层流，即所谓“高效的特殊空气”，它除去了大于0.3μm的尘埃、真菌和细菌孢子等等。
超净空气的流速为24～30m/min，这已足够防止附近空气可能袭扰而引起的污染，这样的流速也不会妨碍采用酒精灯或本生灯对器械等的灼烧消毒。
工作人员就在这样的无菌条件下操作，保持无菌材料在转移接种过程中不受污染。
但是万一操作中途遇到停电，暴露在未过滤空气中的材料便难以幸免污染。
这时应迅速结束工作，并在瓶上作出记号，内中的材料如处于增殖阶段，则以后不再用作增殖而转入生根培养。
如为一般性生产材料，因极其丰富也可弃去。
如处于生根过程，则可留待以后种植用。
超净台电源多采用三相四线制，其中有一零线，连通机器外壳，应接牢在地线上，另外三线都是相线，工作电压是380V。
三线接入电路中有一定的顺序，如线头接错了，风机会反转，这时声音正常或稍不正常，超净台正面无风(可用酒精灯火焰观察动静，不宜久试)，应及时切断电源，只要将其中任何两相的线头交换一下位置再接上，就可解决。
三相线如只接入两相，或三相中有一相接触不良，则机器声音很不正常，应立即切断电源仔细检修，否则会烧毁电机。
这些常识应在开始使用超净台时就向工作人员讲解清楚，免除不应造成的事故与损失。
超净工作台进风口在背面或正面的下方，金属网罩内有一普通泡沫塑料片或无纺布，用以阻拦大颗粒尘埃，应常检查、拆洗，如发现泡沫塑料老化，要及时更换。
除进风口以外，如有漏气孔隙，应当堵严，如贴胶布，塞棉花，贴胶水纸等。
工作台正面的金属网罩内是超级滤清器，超级滤清器也可更换，如因使用年久，尘粒堵塞，风速减小，不能保证无菌操作时，则可换上新的。

二、种子净度工作台/种子净度分析台/种子净度检验台安装和使用说明：使用时，将铁架安装好，将工作台紧固在支架上，放大镜卡脚卡在台面后边缘的左侧，放大镜的电源插头插在工作台后侧的插座上，再连接好工作台后侧右边的总电源线。
整体工作台摆放在通风干燥的环境中使用。
净度工作台台面的灯光采用遥控开关控制，白光台面和偏振光台面的灯光可单独遥控控制，放大镜灯的开关在放大镜上面，单独控制放大镜灯的开启和关闭，用户可以根据实际需要组合使用。
放大和照明装置采用活臂式拉伸设计，使用时可自由拉伸到台面上的每个位置，方便放大和清晰观察。
净度工作台的白光投射观察台和偏振光防眩目透射观察平台都采用最新的高亮度低耗能的冷光源，避免了灯光发出的热量对种子、幼苗、菌落、试验活体样本等影响，从而真正保证了对样本的无损观察。
右侧的偏振光防眩目透射观察台由底座的光源、起偏装置和上盖的检偏装置三部分组成，使用时可以通过旋转上盖即可获得最佳的观察光源，能完全滤除背景光源的干扰，可进行对种子外形评判，切片观察，病理分析，品种鉴定以及种子发芽，幼苗生长叶片分析，菌落计数、米质分析等综合功能，并适于拍摄高质量的照片。
使用时，打开光源，所要观察的种子等样品放在台面上直接观察，组合偏振装置和放大镜即可实现最佳的观察和检测效果。

本次导轨设计的主要任务是根据负载情况选用标准化滚动导轨，在选用过程中，主要进行额定载荷验算2.3.1计算行程长度寿命T sT s =2L S ×n ×60×T h /100(km)工作单行程长度知；L sx =0.15m L sy =0.10m往复次数；n x =np/2 L sx =100×8×10-3/(2×0.15)=2.67 n y =np/2 L sy =100×8×10-3/(2×0.1)=4.00 工作时间寿命；T h =15000(h) ∴行程长度寿命；T sx =2L sx ×n ×60×T h /1000=(2×0.35×2.67×60×15000)/1000 =1682.1(km)T sy =2L sy ×n ×60×T h /1000=(2×0.2×4.00×60×15000)/1000 =1440(km)2.3.2计算动载荷j cj c =13(/)w TcHs f k T f f fF mTf 、cf、Hf、wf 分别由指导书表5，6，7，8查得 Tf=1.0,cf=1.0,Hf=1.0,wf=1.8另取滑座个数 m=4寿命系数一般取k=501(km)作用在滑座上载荷F x =18000N F x =24000N ∴jx c=13(/)4*1*1*1xws f k F T=19689.9N ∴jyc=13(/)4*1*1*1yws f k F T=26275.1N由机电一体化设计基础表2-13查得 故选取滚动导轨型号为HJG —D353步进电机的选择3.1 步距角的选择确定∴α=*360i tδ传动系统传动比i 取4即i=4 工作台脉冲当量δ=0.05 滚动丝杠导程t=8(mm)α=﹙360°×0.05×4﹚／8=9°由设计指导书附录三选择步进电机型号为90BF001由机电一体化设计基础图5-33、5-34查得 减速器采用2级传动传动比分别为i 1=1.8 i 2=2.2 各传动齿轮齿数为；Z 1=20 Z 2 =36 Z 3=20 Z 4=44 模数m=2mm 齿宽b=20mm3.2 步进电机转速校核3.2.1空载起动时电机轴总的负载转距T qT q = T j + T μ + T o由机电一体化设计基础书中式（5-36）分别计算各传动件的转动惯量，其中齿轮的等交叉直径取分度圆直径1d=d 3=mz 1 =mz 3 =2×20=402d = mz 2 =2×36=72 4d = mz 4 =2×44=88 Sd=35.18mm丝杠长度取L=600mm∴J=432L d p π J z1 =J z3 =340.02100.047.832π-⨯⨯⨯⨯=3.92×10-5 (kg·m 2 ) J z2=340.02100.0727.832π⨯⨯⨯⨯ =4104.1-⨯(kg·m 2 )J z4=30.02100.0887.832π⨯⨯⨯⨯=4109.2-⨯(kg·m 2 )J s=340.6100.035187.832π⨯⨯⨯⨯ =4100.3-⨯(kg·m 2 )将各传动件转动惯量及工作台质量折算电动机轴得：总当量负载荷转动惯量 J d =J Z1+(J z1+J z2)/i 12+(J z4+Js)/i 2+(P/2πi)2m=3.9×10-5+(4.1×10-4+3.9×10-5)/1.82+(9.2×10-4+7.03×10-4)/42+(0.008/2π×4)2×80其中工作台小刀架质量为m,取m=80kg取电动机轴自身转动惯量Jm=0.8×10-3(kg ×m 2) 则步近电动机轴的总转动惯量：J=Jm+Jd=1.09×10-3设步近电机空载启动时间为50ms. 最大进给速度：V max =1.0m/min 导轨摩擦系数μ=0.2空载启动时，电动机轴的惯性转矩：T J=Tε=J×W max/∆f=(J×2πi×V max)/(P×∆t)=1.14(N×mm)电动机轴上的当量摩擦转矩：Tμ=(P×FΜ)/2πηi=(P×mgn)/2πηi=(0.008×80×9.8×0.2)/(2π×0.8×4)=0.06(N×m)其中伺服进给链的总效率η=0.8设滚珠丝杠螺母副的预紧力为最大轴向载荷的1/3，则因预紧力而引起，而折算到电动机轴上的附加摩擦转局为：T=P×F0×（1-η0）2=P×F wmax×(1-η02)2/(2πηi×3)=0.008×2800×(1-0.92)2/(2π×0.8×4×3)0.07(N×m)则电动机空载起动时电机轴总的负载转矩:T g=T j+Tμ+Tω=1.14+0.06+0.07=1.27(N×m)3.2.2工作正常时电机轴总负载转矩T g工作台的最大轴向负载折算到电动机轴上的负载转矩：Tω=(P×Fμmax)/2πηi=0.08×2800/(2π×0.8×4)=11.1(N×m)电动机正常工作时电机轴总负载转矩:T g=TΜ+T0+T W=0.06+0.07+11. 1=11.23(N×m)3.2.3 电机最大静转矩T s(1) 按空载启动计算:空载启动上所需电机最大静转矩T s1=T q/c=1.27/0.707=1.80(N×m)C=0.707 由设计指导书表查得:(2) 按正常工作计算:在最大外载荷下工作时所需要电动机最大静转矩: T s2=T g /(0.3~0.5)=1.24/(0.3~0.5)=3.89~2.48(N ×m)Ts ≥max{T s1,T s2} ∴ T s =3.89<[ T s ]∴ 步近电机的最大静转矩满足要求 (3) 频率校核!参考电机的转矩—频特性曲线原则:选用步近电机事应使实际应用的启动频率,运行频率与负载转矩所对应的启动,运行工作点位于该曲线之下,才能保证步近电机不失频地正常工作经校核满足要求∴ 选取90B0.01型步近电机4总语一转眼一个月的课程设计就要结束了。
