夹具开题报告
夹具设计一、题目来源夹具在实际的应用中非常广泛,同时也是工程设计的主要对象之一，因此,本设计题目即来自生产实际，又来源于科研真题。
二、研究的目的和意义机械制造过程中用来固定加工对象，使之占有正确的位置，以接受施工或检测的装置。
又称卡具。
从广义上说，在工艺过程中的任何工序，用来迅速、方便、安全地安装工件的装置，都可称为夹具。
随着我国现代工业技术的发展,对机械传动装置的技术性能和经济指标提出了越来越高的要求,普通夹具已经不能满足现代工业大批量高效生产的需要,而研制新型随行夹具是机械行业中重要的课题之一。
随行夹具主要是在自动生产线、加工中心、柔性制造系统等自动化生产中，用于外形不太规则、不便于自动定位、夹紧和运送的工件。
工件在随行夹具上安装定位后，由运送装置把随行夹具运送到各个工位上。
随行夹具一般以其底平面和两定位孔在机床上定位,并由机床工作台的夹紧机构夹紧,从而保证工件与刀具的相对位置。
当工件加工精度要求较高时，常把随行夹具的底平面分开成为定位基面和运输基面,以保护定位基面的精度.随行夹具属于专用夹具范围，其装夹工件部分需按工件外形和工艺要求设计。

夹具设计外文翻译
Application and developmentOf case based reasoning in fixture designFixtures are devices that serve as the purpose of holding the workpiece securely and accurately, and maintaining a consistent relationship with respect to the tools while machining. Because the fixture structure depends on the feature of the product and the status of the process planning in the enterprise, its design is the bottleneck during manufacturing, which restrains to improve the efficiency and leadtime. And fixture design is a complicated process, based on experience that needs comprehensive qualitative knowledge about a number of design issues including workpiece configuration, manufacturing processes involved, and machining environment. This is also a very time consuming work when using traditional CAD tools (such as Unigraphics, CATIA or Pro/E), which are good at performing detailed design tasks, but provide few benefits for taking advantage of the previous design experience and resources, which are precisely the key factors in improving the efficiency. The methodology of case based reasoning (CBR) adapts the solution of a previously solved case to build a solution for a new problem with the following four steps: retrieve, reuse, revise, and retain [1]. This is a more useful method than the use of an expert system to simulate human thought because proposing a similar case and applying a few modifications seems to be self explanatory and more intuitive to humans .So various case based design support tools have been developed for numerous areas[2-4], such as in injection molding and design, architectural design, die casting die design, process planning, and also in fixture design. Sun used six digitals to compose the index code that included workpiece shape, machine portion, bushing, the 1st locating device, the 2nd locating device and clamping device[5]. But the system cannot be used for other fixture types except for drill fixtures, and cannot solve the problem of storage of the same index code that needs to be retained, which is very important in CBR[6].1. Construction of a Case Index and Case Library1.1 Case indexThe case index should be composed of all features of the workpiece, which are distinguished from different fixtures. Using all of them would make the operation in convenient. Because the forms of the parts are diverse, and the technology requirements of manufacture in the enterprise also develop continuously, lots of features used as the case index will make the search rate slow, and the main feature unimportant, for the reason that the relative weight which is allotted to every feature must diminish. And on the other hand, it is hard to include all the features in the case index.1.2 Hierarchical form of CaseThe structure similarity of the fixture is represented as the whole fixture similarity, components similarity and component similarity. So the whole fixture case library, components case library, component case library of fixture are formedcorrespondingly. Usually design information of the whole fixture is composed of workpiece information and workpiece procedure information, which represent the fixture satisfying the specifically designing function demand. The whole fixture case is made up of function components, which are described by the function components’ names and numbers. The components case represents the members. (function component and other structure components，main driven parameter, the number, and their constrain relations.) The component case (the lowest layer of the fixture) is the structure of function component and other components. In the modern fixture design there are lots of parametric standard parts and common non standard parts. So the component case library should record the specification parameter and the way in which it keeps them.2. Strategy of Case RetrievalIn the case based design of fixtures ,the most important thing is the retrieval of the similarity, which can help to obtain the most similar case, and to cut down the time of adaptation. According to the requirement of fixture design, the strategy of case retrieval combines the way of the nearest neighbor and knowledge guided. That is, first search on depth, then on breadth; the knowledge guided strategy means to search on the knowledge rule from root to the object, which is firstly searched by the fixture type, then by the shape of the workpiece, thirdly by the locating method. For example, if the case index code includes the milling fixture of fixture type, the search is just for all milling fixtures, then for box of workpiece shape, the third for 1plane+ 2pine of locating method. If there is no match of it, then the search stops on depth, and returns to the upper layer, and retrieves all the relative cases on breadth.2.1 Case adaptationThe modification of the analogical case in the fixture design includes the following three cases:1) The substitution of components and the component;2) Adjusting the dimension of components and the component while the form remains;3) The redesign of the model.If the components and component of the fixture are common objects, they can be edited, substituted and deleted with tools, which have been designed.2.2 Case storageBefore saving a new fixture case in the case library, the designer must consider whether the saving is valuable. If the case does not increase the knowledge of the system, it is not necessary to store it in the case library. If it is valuable, then the designer must analyze it before saving it to see whether the case is stored as a prototype case or as reference case. A prototype case is a representation that can describe the main features of a case family. A case family consists of those cases whose index codes have the same first 13 digits and different last three digits in the case library. The last three digits of a prototype case are always “000”. A reference case belongs to the same family as the prototype case and is distinguished by the different last three digits.From the concept that has been explained, the following strategies are adopted:1) If a new case matches any existing case family, it has the same first 13 digits as an existing prototype case, so the case is not saved because it is represented well by the prototype case. Or is just saved as a reference case (the last 3 digits are not “000”, and not the same with others) in the case library.2) If a new case matches any existing case family and is thought to be better at representing this case family than the previous prototype case, then the prototype case is substituted by this new case, and the previous prototype case is saved as a reference case.3) If a new case does not match any existing case family, a new case family will be generated automatically and the case is stored as the prototype case in the case library.3. ConclusionCBR, as a problem solving methodology, is a more efficient method than an expert system to simulate human thought, and has been developed in many domains where knowledge is difficult to acquire. The advantages of the CBR are as follows: it resembles human thought more closely; the building of a case library which has self learning ability by saving new cases is easier and faster than the building of a rule library; and it supports a better transfer and explanation of new knowledge that is more different than the rule library. A proposed fixture design framework on the CBR has been implemented by using Visual C ++, UG/Open API in U n graphics with Oracle as database support, which also has been integrated with the 32D parametric common component library, common components library and typical fixture library. The prototype system, developed here, is used for the aviation project, and aids the fixture designers to improve the design efficiency and reuse previous design resources.基于事例推理的夹具设计研究与应用夹具是以确定工件安全定位准确为目的的装置，并在加工过程中保持工件与刀具或机床的位置一致不变。

Machining process is a process generated shape, in this process, Drivers device on the workpiece material to be in the form of chip removal. Although in some occasions, the workpiece under no circumstances, the use of mobile equipment to the processing, However, the majority of the machining is not only supporting the workpiece also supporting tools and equipment to complete.Machining know the process has two aspects. Small group of low-cost production. For casting, forging and machining pressure, every production of a specific shape of the workpiece, even a spare parts, almost have to spend the high cost of processing. Welding to rely on the shape of the structure, to a large extent, depend on effective in the form of raw materials. In general, through the use of expensive equipment and without special processing conditions, can be almost any type of raw materials, mechanical processing to convert the raw materials processed into the arbitrary shape of the structure, as long as the external dimensions large enough, it is possible. Because of a production of spare parts, even when the parts and structure of the production batch sizes are suitable for the original casting, Forging or pressure processing to produce, but usually prefer machining.Strict precision and good surface finish, Machining the second purpose is the establishment of the high precision and surface finish possible on the basis of. Many parts, if any other means of production belonging to the large-scale production, Well Machining is alow-tolerance and can meet the requirements of small batch production. Besides, many parts on the production and processing of coarse process to improve its general shape of the surface. It is only necessary precision and choose only the surface machining. For instance, thread, in addition to mechanical processing, almost no other processing method for processing. Another example is the blacksmith pieces keyhole processing, as well as training to be conducted immediately after themechanical completion of the processing.Primary Cutting ParametersCutting the work piece and tool based on the basic relationship between the following four elements to fully describe : the tool geometry, cutting speed, feed rate, depth and penetration of a cutting tool.Cutting Tools must be of a suitable material to manufacture, it must be strong, tough, hard and wear-resistant. Tool geometry -- to the tip plane and cutter angle characteristics -- for each cutting process must be correct.Cutting speed is the cutting edge of work piece surface rate, it is inches per minute to show. In order to effectively processing, and cutting speed must adapt to the level of specific parts -- with knives. Generally, the more hard work piece material, the lower the rate.Progressive Tool to speed is cut into the work piece speed. If the work piece or tool for rotating movement, feed rate per round over the number of inches to the measurement. When the work piece or tool for reciprocating movement and feed rate on each trip through the measurement of inches. Generally, in other conditions, feed rate and cutting speed is inversely proportional to。
机械加工零件的工艺及夹具设计方案(中英文对照)
机械加工零件的工艺及夹具设计摘要：本文对机械加工零件的结构和工艺进行了分析，确定了机械加工工艺路线，夹具在机械加工中所占的地位和重要性，以及夹具设计。
随着科学的日益发展进步和国家产业政策的调整,工程机械行业已成为没有政策壁垒的完全竞争行业关键词：技术背景/发展趋势/工序/定位方案1 机械加工历史背景及其意义机械制造业是一个古老而永远充满生命力的行业。
随着现代工业的发展，对机械产品的要求越来越高，机械制造工艺也在日新月异地发展。
自新中国成立以来，我国的制造技术与制造业得到了长足发展，一个具有相当规模和一定技术基础的机械工业体系基本形成。
改革开放二十多年来，我国制造业充分利用国内国外两方面的技术资源，有计划地推进企业的技术改造，引导企业走依靠科技进步的道路，使制造技术、产品质量和水平及经济效益发生了显著变化，为推动国民经济的发展做出了很大的贡献。
尽管我国制造业的综合技术水平有了大幅度提高，但与工业发达国家相比，仍存在阶段性差距。
进入二十一世纪，我国发展经济的主导产业仍然是制造业，特别是在我国加入世贸组织后，世界的制造中心就从发达国家迁移到了亚洲，我国有廉价的劳动力和广大的消费市场，因此，我国工业要想发展，就需要有相应的技术和设备来支持。
机械工业是国民经济的装备工业；是科学技术物化的基础；是高新技术产业化的载体；是国防建设的基础；是实现经济快速增长的重要支柱；也是为提高人民生活质量、提供消费类机电产品的供应工业。
它对国民经济运行的质量和效益、产业结构的调整和优化具有极其重要的作用。
2 机械行业的现状及发展趋势随着社会的发展，各种机械逐渐运用到各个行业中，不管是在农用、军用、工用等方面，离开了机械的操作就谈不上效率，因此，从某中角度上来说，一个国家的经济实力、社会地位，和机械行业的发展是密不可分的。
各工业化国家经济发展的历程表明，没有强大的装备制造业，就不可能实现国民经济的工业化、现代化和信息化[3]。
