设计简介
本文是对万向节滑动叉零件加工应用及加工的工艺性分析，主要包括对零件图的分析、毛坯的选择、零件的装夹、工艺路线的制订、刀具的选择、切削用量的确定、加工工艺文件的填写。选择正确的加工方法，设计合理的加工工艺过程。此外还对支架零件的两道工序的加工设计了专用夹具.
机床夹具的种类很多，其中，使用范围最广的通用夹具，规格尺寸多已标准化，并且有专业的工厂进行生产。而广泛用于批量生产，专为万向节滑动叉工件加工工序服务的专用夹具，则需要各制造厂根据工件加工工艺自行设计制造。本论文夹具设计的主要内容是设计两套夹具。

Abstract：
This paper is the analysis of technology on the cardan sliding fork parts processing application and processing, mainly including the parts of the analysis, the choice of blank, the clamping, the formulation process route, tool selection, cutting, processing documents to determine. Choose the correct methods for processing, processing process design reasonable. In addition also processes two parts of the stent design special fixture
Many types of machine tool fixture, wherein, the use scope broadest generaljig, sizes have been standardized, and has a professional production plant. But widely uses in the volume production, specially dedicated fixture for the cardan sliding fork parts processing services, requires the factory according to the workpiece processing technology to design and manufacture. The main content of this thesis is to design two sets of fixture design fixture.
Keywords：the cardan sliding fork, machining process, fixture, design
