课程设计（论文）题目变速叉零件的机械加工工艺及工装设计所属部所属专业机械设计与制造所属班级学号学生姓名指导教师起讫日期摘要此次设计是对变速叉零件的加工工艺和夹具设计，其零件为锻件，具有体积小，零件复杂的特点，由于面比孔易加工，在制定工艺规程时，就先加工面，再以面为基准来加工其它，其中各工序夹具都采用专用夹具,并以操作简单的手动夹紧方式夹紧，其机构设计简单，方便且能满足要求。关键词变速叉，加工工艺，专用夹具，设计AbstractThisdesignistodialsforksthecomponentstheprocessingcraftandthe激gdesign,itscomponentsaretheforging,hasthevolumetobesmall,componentscomplexcharacteristic,Becausethesurfaceiseasierthantheholetoprocess,whenformulationtechnologicalprocess,firstthemachinedsurface,thenprocessesothertakethesurfaceasthedatum,Inwhichvariousworkingprocedures激gallusestheunitclamp,specialregardingprocessesthebigendofhole,thetroughanddrillsthecapitellumholeinclineeyeletintheworkingprocedure,Chooseslocatemodewhichtwosellsatthesametime,andoperatesthesimplemanualclampwayclamp,itsorganizationdesignissimple,theconveniencealsocansatisfytherequest.Keywords：Dialsthefork,theprocessingcraft,unitclamp,design目录摘要...........................................................................................................................................IAbstract......................................................................................................................................II目录.........................................................................................................................................III第1章绪论................................................................................................................................11.1机械加工工艺概述.......................................................................................................11.2机械加工工艺流程.......................................................................................................11.3夹具概述.......................................................................................................................21.4机床夹具的功能...........................................................................................................21.5机床夹具的发展趋势...................................................................................................31.5.1机床夹具的现状................................................................................................31.5.2现代机床夹具的发展方向................................................................................3第2章变速叉的分析................................................................................................................62.1变速叉的工艺分析.......................................................................................................62.2变速叉的工艺要求.......................................................................................................6第3章工艺规程设计................................................................................................................73.1加工工艺过程...............................................................................................................73.2确定各表面加工方案...................................................................................................73.2.1影响加工方法的因素.....................................
