CA10B解放牌汽车前刹车调整臂外壳加工工艺设计及程序编制课程设计说明书——25页 此份资料不含图纸及工序卡
摘 要
机械加工工艺流程是工件或者零件制造加工的步骤,采用机械加工的方法,直接改变毛坯的形状、尺寸和表面质量等,使其成为零件的过程称为机械加工工艺过程。
本设计首先介绍了前刹车调整臂外壳的作用和工艺分析,其次确定毛坯尺寸,然后进行了工艺规程设计,最后进行夹具设计。此次设计是对前刹车调整臂外壳的加工工艺和夹具设计,其零件为铸件,具有体积小,零件结构简单的特点,由于面比孔易加工,在制定工艺规程时,就先加工面,再以面为基准来加工其它,其中各工序夹具都采用专用夹具,其机构设计简单,方便且能满足要求。

Abstract
Machining process is a part or parts manufacturing and processing steps, mechanical processing methods, directly change the rough shape, size and surface quality, making it part of the process called machining process.
The design first introduced the Former brake slack adjusters shell role and process analysis, followed to determine the rough size, then the process planning, the final fixture design. The design is a Former brake slack adjusters shell processing and fixture design, the parts of casting, with small, simple structure, the characteristics of parts, ease of processing because surface than the hole in the development process of order, it faces the first processing , then the other side as a benchmark to process, in which the processes are using a dedicated jig fixture, their mechanical design is simple, convenient and can meet the requirements.
Keywords: Former brake slack adjusters shell; process analysis; process planning
