1、毕业设计题目CA6140车床后托架零件的加工工艺及工装英文题目AftertheCA6140latheprocessandtoolingbracket学生姓名:申请学位门类:学号:专业:学院:指导教师:职称:二0一六年六月摘要本次毕业设计是CA6140车床后托架加工工艺及工装夹具设计。本次设计首先需要通过对CA6140车床后托架零件图进行分析,了解工件基本的结构形式,确定工件具体的技术要求,然后对工件各个组成表面选择较好的加工方法,制定出较为合理的工艺规程。同时,夹具设计在机械加工工艺设计过程中的起到非常重要的作用,在整个机械加工工艺过程中,夹具除了起到夹紧和固定作用外,还保证了加工工
2、件的加工精度、提高了加工效率。因此,夹具设计在整个设计过程中是必不可少的。在工艺设计的过程当中,要根据实际的生产要求,进行研究,分析,制定出合理的设计方案,在进行具体工艺规程的方案设计。关键词:后托架;夹具;定位方案;夹紧力;夹具。ABSTRACTThisgraduationdesignisthebracketaftertheCA6140latheprocessingtechnologyandfixturedesign.BracketafterthedesignneedtofirstthroughtotheCA6140lathepartsdiagramanalysis,underst
