万向节滑动叉零件图
摘要
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。本夹具设计的主要内容是设计。

Title： Design Festival sliding fork parts process and fixture universal
Abstract：
This paper is an analysis of the application and processing technology of the universal joint sliding fork parts, including the analysis of the part drawing, the selection of the blank, the clamping of the parts, the formulation of the process route, the selection of the cutting tool, the determination of the cutting parameters, and the filling of the processing technology documents. Choose the right processing method and design the reasonable processing process. In addition, a special fixture is designed for the two processes of bracket parts
There are many kinds of jigs and fixtures. Among them, the mostwidely used universal fixture has standardized specifications and sizes, and there are professional factories for production. The special fixture,which iswidely used in mass production and serves theworking procedure of universal joint sliding fork, needs to be designed and manufactured by each manufacturer according to theworkpiece processing technology. The main content of fixture design in this paper is design.
Keywords: universal joint sliding fork, processing technology, special fixture, design
