山西农业大学课程设计(论文) CA6140车床后托架 加工工艺及夹具设计 学生姓名: 蒙建国 学生学号: 2006151111 院 (系): 工学院 专业:机械设计制造及自动化 指导教师: 张秀全 二〇一零年四月 摘 要 在生产过程中,使生产对象(原材料,毛坯,零件或总成等)的质和量的状态发生直接变化的过程叫工艺过程,如毛坯制造,机械加工,热处理,装配等都称之为工艺过程。在制定工艺过程中,要确定各工序的安装工位和该工序需要的工步,加工该工序的机车及机床的进给量,切削深度,主轴转速和切削速度,该工序的夹具,刀具及量具,还有走刀次数和走刀长度,最后计算该工序的基本时间,辅助时间和工作地服务时间。 关键词 工序,工艺,工步,加工余量,定位方案,夹紧力 ABSTRACT Enable producing the target in process of production (raw materials, the blank , state of quality and quantity on part become always ) take place direct course of change ask craft course, if the blank is made, machining, heat treatment , assemble etc. and call it the craft course. In the course of making the craft , is it confirm every erector location and worker step that process need this of process to want, the locomotive of processing , this process , and the entering the giving amount of the lathe, cut depth , the rotational speed of the main shaft and speed of cutting, the jig of this process, the cutter and measuring tool, a one hundred sheets of number of times still leaves and a one hundred sheets of length leaves, calculate basic time of this process , auxiliary time and service time of place of working finally. Keywords: The process, worker one, workers step , the surplus of processing, orient the scheme , clamp strength 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc138299637 摘 要 PAGEREF _Toc138299637 \h I HYPERLINK \l _Toc138299638 ABSTRACT PAGEREF _Toc138299638 \h II HYPERLINK \l _Toc138299640 1 CA6140机床后托架加工工艺 PAGEREF _Toc138299640 \h 3 HYPERLINK \l _Toc138299641 1.1 CA6140机床后托架的工艺分析 PAGEREF _Toc138299641 \h 3 HYPERLINK \l _Toc138299642 1.2 CA6140机床后托架的工艺要求及工艺分析 PAGEREF _Toc138299642 \h 3 HYPERLINK \l _Toc138299643 1.2.1 CA6140机床`后托架的技术要求 PAGEREF _Toc138299643 \h 4 HYPERLINK \l _Toc138299644 1.3 加工工艺过程 PAGEREF _Toc138299644 \h 4 HYPERLINK \l _Toc138299645 1.4 确定各表面加工方案 PAGEREF _Toc138299645 \h 4 HYPERLINK \l _Toc138299646 1.4.1 在选择各表面及孔的加工方法时,要综合考虑以下因素 PAGEREF _Toc138299646 \
