摘要
本文是对齿轮轴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，专为齿轮轴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 the gear shaft parts processing technology application and processing, including the parts diagram analysis, the choice of blank, parts of the fixture, the formulation of the process route, tool selection, cutting, processing documents. Choose the correct processing methods, design the reasonable process. In addition, processing of two processes to support part of the design of special fixture.
Many kinds of the machine tools fixture, the fixture, the most widely used, the size has been standardized, and there is a professional factory production. But widely uses in the volume production, specially the special fixture for gear shaft workpiece machining processes and services, to the factory according to the workpiece machining process to design and manufacture. The main content of this thesis is to design two sets of fixture design fixture.
