摘要
本次支座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。
就支座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。本设计主要研究支座的零件结构，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。

序言
机械制造业是制造具有一定形状位置和尺寸的零件和产品，并把它们装备成机械装备的行业。机械制造业的产品既可以直接供人们使用，也可以为其它行业的生产提供装备，社会上有着各种各样的机械或机械制造业的产品。我们的生活离不开制造业，因此制造业是国民经济发展的重要行业，是一个国家或地区发展的重要基础及有力支柱。从某中意义上讲，机械制造水平的高低是衡量一个国家国民经济综合实力和科学技术水平的重要指标。
