止动箍零件图A4
这篇写的题目是止动箍零件加工工艺及夹具设计，本次夹具设计钻削Ф12H7圆柱孔专用夹具。
一开始进行设计的时候，我翻阅了很多相关的材料，对于夹具怎么进行定位，怎么进行夹紧等等相关的知识都了解了一下，还有对于夹具现在的状况的有关知识进行了全面的了解。本次设计的主要内容有：对零件结构的分析，确定零件的制造形式，绘制零件图和毛坯图；然后对每一个步进行计算，确定切削用量，编写加工工艺过程卡和加工工序卡；确定加工工序的定位方案和夹紧方案，选择定位元件和夹紧元件等，对其定位误差进行分析；绘制夹具装配图及所有非标零件图；撰写设计说明书，对本次设计进行总结。

ABSTRACT
In the modern production inside, fixture in the processing time isvery critical, in the production of equipment on the use of time, can not be discarded a key part. Processing the scope of this industry is relativelywide, the production of parts,whether it is structure or change isvery large, and now basically do not have a common fixture to the production. In thisway, the special fixture in the modern productionwhich isvery important.
This paper iswritten in the title of the only hoop parts processing technology and fixture design, the fixture design drillingФ12H7 cylindrical hole special fixture.
At the beginning of the paper design, I read a lot of related materials, how to locate the fixture, how to clamp and so on the relevant knowledge are aware of the situation, aswell as the current situation of the fixture of the relevant knowledge of a comprehensive To understanding. The main contents of this design are: the analysis of the parts structure, determine the parts of the manufacturing form, drawing parts and rough map; and then for each step to determine the amount of cutting, the preparation of processing process cards and processing process card; Processing positioning method and clamping program, select the positioning elements and clamping components, etc., to analyze the positioning error; drawing fixture assembly drawings and all non-standard parts map;write design specifications, the design summary.
Keywords：Stop hoop, processing technology, fixture design, drilling,Ф12H7 cylindrical hole
