设计简介
本文是对曲柄板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156FM凸轮轴调节叉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，专为某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镗床夹具和铣床夹具，最后设计了一副检验夹具。

Abstract：
This article is on the fork parts processing application and processing technology and analysis, including the spare parts diagram analysis, the choice of blank, parts of the clamping, the craft route making, tool selection, the determination of cutting conditions, processing documents. Choose the correct processing method, the rational design of machining process. In addition to the156FM camshaft adjusting fork parts of the two process designing special fixture.
Machine tool fixture of many kinds, among them, the most widely used common fixture, size specifications have been standardized, and a professional production plant. While widely used in batch production, designed for a certain workpiece processing services for the fixture, it needs each factory according to workpiece machining technology to design and manufacture. In this paper, fixture design are the main contents of design jig boring machine and milling fixture, the design of a test fixture.
Key Words: Crank plate，Processing technology, processing method, process documentation, fixture
