摘要 本次泵体设计内容涉及机械设计，夹具设计，机械制图，工艺设计，AutoCAD、机，钻床夹具设计，械制造基础、钻床加工实例、公差配合，与互换性测量技术、等多方面的知识。 就泵体加工工艺及夹具设计而言，此设计包括对零件的工艺分析，制定工艺过程卡和工序卡，专用夹具设计等三大部分。本设计主要研究泵体的零件结构，主要是以加工工艺方案和夹具设计来阐述。首先对零件图纸进行分析，确定零件的各个尺寸，精度生产类型等要素，然后再进行零件毛坯的选用，接着对零件进行工艺过程分析，然后计算出切削用量夹紧力等要素，最后再根据加工工艺工序设计出相应的夹具。 关键词：泵体工艺规程；定位；压紧；导向，夹具，误差 Abstract The pump body graduatio
