1、 I 摘摘 要要 夹具在制造业被广泛应用，是产品制造各工艺阶段中十分重要的工艺 装备之一，生产中所使用夹具的质量、工作效率，及夹具使用的可靠性， 都对产品的加工质量及生产效率有着决定性的影响。所以对夹具的概念进 行了解，再进行机床夹具的设计，从定位到误差分析再到确保加工精度， 然后计算出加紧力，确定加紧点位数等细节计算是非常重要的。 本文首先对零件的作用和工艺性进行了分析，详细介绍了零件加工工 艺过程的制定:1,定位基准的选择。2，制定加工工艺路线。3，选择加工设 备及工艺装备。4，确定切削用量及基本工时。然后介绍了夹具的设计及计 算，包括零件本工序的加工要求分析，确定夹具类型，拟定定位方案和
2、选 择定位元件确定夹紧方案确定对刀装置。最后进行了建模和运动仿真以及 静态分析以此获得设计目的。 关键词关键词：套筒座；加工工艺； 专用夹具； 运动仿真； 静态分析。 II Abstract Fixture in the manufacturing industry are widely used, is the product of manufacturing each craft phase is very important in process equipment, used in the production of quality, working efficiency of jig
3、 and fixture, use reliability, to product processing quality and production efficiency has the decisive influence. So the fixture on the concept of understanding, then the machine tool fixture design, from the positioning error analysis and to ensure the accuracy of processing, and then calculate th
4、e number of points to determine to details of calculation is very important. In this paper, parts of the role and process are analyzed, introduces in detail the components processing technological process formulation:1, selection of location datum. 2, develop process route. 3, selection of machining equipment and process equipment. 4, determine the amount of cutting and the basic working hours. Then introduced the jig design and calculation, including parts of the process requirements analysis
