机械制造技术课程设计-CA6140车床输出轴工艺及钻2-φ8孔夹具设计【全套图纸】.doc

辽宁工程技术大学 课 程 设 计 题 目：输出轴（CA6140车床） 全套图纸，加153893706 班　　级：　机电06-3 姓　　名：　 指导教师：　 完成日期：　2009.7.1 一、设计题目　　 输出轴（CA6140车床）包括 本文首先介绍了输出轴的作用和工艺分析.然后，根据零件的性质和零件图上各端面的粗糙度确定毛坯的尺寸和械加工余量。最后拟定钻孔的工艺路线图，制定该工件的夹紧方案，画出夹具装配图。 本次课程设计主要是应用机械制造技术，是一次深入的综合性的总复习 Abstract Designing that this time is that the CA6140 lathe exports 2*Φ8 holes. The part including the workpiece being processed pursues , the workpiece blank pursues , clamp assembling picture , the clip pursue concretely every sheet, the machine work procedure card draws and the working procedure card takes a look respectively once. The part , handicraft frock design and reform exporting axis main part as the power set are having direct impact to whose mass and function. The effect and handicraft having introduced the axis outputings first analyse the main body of a book. And then, the dimension and instrument having pursued every end face harshness according to part character and part ascertain a blank process a margin. The at last designs the handicraft route chart drilling , works out the fastening motion scheme being workpieces turn , draws up clamp assembling picture. Time of curriculum design is the general review applying the machinofacture technology , being a thorough comprehensiveness originally mainly. By current curriculum design, process knowing and knowing general machine part productive technology, the knowledge consolidating and deepening the technology basic course and specialized course have already learned, integrates theory with practice. Temper self analytical problem , the ability to solve problems out of , be that job the days to come lays down one is fine basis, and be that follow-up course study about finishes striking a basis. 目 录 1零件的工艺分析及生产类型的确定 1 1.1零件的用途 1 1.2零件的工艺性 1 1.2.1分析、审查产品的零件图和装配图 1 1.2.2零件的结构工艺性分析 1 1.3确定零件的生产类型 2 2确定毛胚、绘制毛胚简图 2 2.1选择毛胚 2 2.2确定毛胚的机械加工余量和尺寸公差 3 2.2.1毛胚的机械加工余量 3 2.2.2毛胚的尺寸公差 3 2.2.3加工余量、工序尺寸和工差的确定 4 2.2.3绘制零件毛坯简图 5 3拟定零件的工艺路线 5 3.1定位基准的选择 5 3.1.1精基
