摘 要
本次毕业设计的题目是CA141左转向节规程及工装设计。我主要需要完成的包括加工工艺的安排以及两种专用机床夹具设计。为了保证加工零件的精度同时节约成本和缩短加工周期以及提高加工效率，那么一个良好的工艺安排以及专用夹具的设计就是必不可少的了。在工艺的安排上不但要考虑合理的加工要求还要考虑到操作者以及加工机械的安全。同时夹具的设计上也要考虑到使用的安全性和经济性以及安装和拆卸上的方便性。设计一个良好的工艺工装安排路线那么必须要经过对加工件的详细分析以及周密的考虑后才能得出。所以分析问题是解决问题的关键，同时还要反复的调整，来寻求最好的一个路线。这样才能让工艺路线更加的完美，才能保证工件的加工精度和加工效率以及节约材料。

Abstract
The graduation design is the subject of CA141 car’s left steering process tooling. I mainly need to complete including Processing craft arrangement as well as special-purpose drill jig design.
In order to guarantee the processing components the precision Simultaneously saves cost and the reduction processing cycle as well as the enhancement processing efficiency, Then a good craft arrangement as well as unit clamp's design was essential. Not only in the craft arrangement must consider that the reasonable processing request also needs to consider the operator as well as processes machinery's security. Simultaneously jig's design also needs to consider the use in secure and efficient as well as the installment and the disassemblage conveniences. Designs a good craft work clothes arrangement route that to probably pass through to the job multianalysis,After as well as thorough consideration, can obtain. Therefore the analysis question solves the question key, meanwhile must the repeated adjustment, Seeks a best route. Seeks a best route to be able to let craft route even more perfect like this, can guarantee that the work piece the working accuracy and the processing efficiency as well as save the material.
