转子泵泵体工艺及回转式钻6XФ13孔夹具设计 摘要 在现代化的生产里面，夹具在加工的时候是非常关键的，在设备上进行生产使用的时候，是不能丢弃的一个关键部分。加工这个行业范围是比较广的，生产的零部件不管是构造也好，还是外部形状也好，变化是非常大的，现在基本上都不用通用夹具来进行生产了。这样来看，专用夹具在现代化的生产里面是非常重要的。 这篇写的题目是转子泵泵体工艺及回转式钻孔夹具设计，依据任务书需要设计钻削6XФ13孔回转式专用夹具。 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。 设计好了之后，要进行有关的分析，之后将数据都算出来，这样一来整个就都写好了，不仅将我大学几年学习的知识都复习了一次，还为我将来的实践工作做了很好的铺垫。 关键词：转子泵泵体，工艺，6XФ13，回转式，专用夹具 Abstract I
