铣左端面夹具装配图——A0
摘要
悬置支架设计一共分三部分，现分述如下：悬置支架的工艺分析、加工工艺、铣左端面的夹具设计。
悬置支架的工艺分析，首先分析悬置支架结构特点，接着编写工艺规程，查找各个加工表面的加工余量，绘制悬置支架毛坯图，工序卡图，最后对各加工工序的切削用量、进给量、切削速度和工时等进行计算。
悬置支架铣左端面的夹具设计，首先依据工艺规程、工件图及六点定位原理，采用的定位元件为：支承板和A型固定式定位销。夹紧方案采用六角螺母、圆垫圈、螺杆、垫块、B型U形压板和六角法兰面螺母等组成的螺旋夹紧机构夹紧工件。

Abstract
The graduation design of the suspension bracket is divided into three parts, which are described as follows: process analysis, processing technology, and fixture design for milling the left end face of the suspension bracket.
For the process analysis of the suspension bracket, first analyze the structural characteristics of the suspension bracket, then prepare the process procedure, find the machining allowance of each machining surface, draw the blank drawing of the suspension bracket and the process card diagram, and finally calculate the cutting amount, feed rate, cutting speed and working hours of each machining process.
The fixture design for milling the left end face of the suspension bracket is based on the process specification, workpiece drawing and six point positioning principle. The positioning elements used are: support plate and A-type fixed positioning pin. The clamping scheme adopts a screw clamping mechanism composed of hexagon nut, round washer, screw, cushion block, B-shaped U-shaped pressing plate and hexagon flange nut to clamp the workpiece.
Key words: suspension bracket; Process analysis; Fixture design
