箱体CAD重构及其工艺设计 作者姓名：黎 卯 专业名称：机械工程及自动化 指导教师：周立华 讲师 摘要 CAD和PRO/E绘制箱体二维和三维图纸， ………………………………………. 关键词 ：箱体 工艺设计 CAD PRO/E  The box is an important part of machine tools and gear belonging to a large number of types of production, the material commonly used gray cast iron, machine tools and gear in many parts fused so that they maintain the correct positional relationship to transmit torque or changespeed to complete the required movement. The casing is mainly composed of the box seat, cover, its structure is relatively complex, there is usually some of the dimensional accuracy and positional accuracy require a higher bearing hole and the positioning pin holes in the casing, they are mainly used in the positioning of the related parts or in the processing process for the positioning of two parts, machining box larger than, the difficulty is quite large, relatively high demands on processing and fixture design. The rapid development of enterprises not only to ensure the quality of the parts processing, but also to improve production efficiency, reduce production costs, which is the main direction of development of the modern foreign machining process. In this thesis, processing route through the box parts chart and its structure, the use of CAD and PRO / E and then on the box to draw the Cabinet two-dimensional and three-dimensional drawings, process design, tooling design and machining accuracy, intended , the formation of a machining process card processing operations card, if necessary fixture design. ……………………………………. Keywords: Box, Process design, CAD, PRO/E目录 摘要 I Abstract II 目录 III 前言 5 6 1.1 箱体零件的功用及结构工艺特点 6 1.2 箱体零件的主要技术要求 6 1.3 箱体零件的材料与毛坯 2 箱体结构及其工艺过程 7 2.1 箱体结构工艺性 7 2.2 箱体机械加工工艺过程及其工艺分析 7 箱体零件的常用加工方法 8 3.1 箱体的平面加工 8 3.2 箱体类零件孔系加工 8 分离式箱体机械加工工艺规程制定 10 4.1 机械加工工艺规程概述 10 4.1.1 工艺过程的组成 10 4.1.2 工艺规程的作用 10 4.1.3 制定工艺规程的原则 10 4.1.4 制定工艺规程的原始资料 4.1.5 制定工艺规程的步骤 4.2 分离式箱体加工工艺分析 10 4.2.1 分离式箱体的主要技术要求 10 4.2.2 分离式箱体的工艺特点 10 4.3 分离式箱体
