毕业设计（论文） 题目名称：摆动钳零件机加工工艺与机床专用夹具的设计 英文题目：The processing technology and equipment of Swinging clamp parts 函授站名称： 班 级： 学生姓名： 指导教师： 年 月 摘 要 本论文是关于纺机配件摆动钳的加工工序、设计方案、计算过程以及铣钳口的夹具设计。摆动钳表面加工方法的选择、加工顺序的安排、工序集中与分散的处理、加工阶段的划分、机床和工艺装备的选择、加工余量与工序尺寸及公差的确定等都是编制工艺规程的主要问题。而夹具设计所面临的是设计方案的确定、定位元件的选择、定位误差的分析与计算、夹紧力的计算、夹具体毛坯结构及夹具元件配合的确定。还有摆动钳毛坯图、零件图和夹具装配图的绘制，如何保证用摆动钳的技术条件是加工过程最为重要的问题，而夹具也起着至关重要的作用。 摆动钳的合理结构设计、加工工艺性设计，保证摆动钳的加工质量，对提高生产效率有着重要意义，它是保证产品质量的关键所在。通过对摆动钳加工过程的设计，可以发现一个产品的设计需要各个加工过程很好的配合才能成功。 关键词：摆动钳； 工艺； 夹具； 夹紧； 定位 Abstract  In this paper, the design of the Swinging clamp, design, calculation and design of drilling jig. Fork the surface of the choice of processing methods, processing sequence of the arrangement, process centralization and decentralization of treatment, the division stage of processing, machine tools and process equipment selection, allowance and processes determine the size and tolerance of the preparation process are the main point of order problem. Fixture Design and facing the program is designed to identify, locate component selection, positioning errors of analysis and calculation, the calculation of clamping force, the specific folder structure and the rough with the determination of fixture elements. There are Swinging clamp blank map, fixture assembly parts diagram and mapping how to ensure the technical conditions fork is the most important process, and fixture also plays a vital role.  Swinging clamp reasonable structural design, design process to ensure quality processing fork, to improve the productivity of great significance, it is to ensure that the key to product quality. Swinging clamp through the design process can be found in a product design process requires a good co-ordination to succeed.
