摘要 应用组合机床加工大批量零件，快捷高效，生产效率高是机械加工的发展方向。本次毕业设 计的题目是“钻曲轴箱前端面的孔”。本组合机床要求能实现同时钻四孔。在工艺制定过程 中，通过批量的进行钻前端面的加工方案，并寻求最佳的工艺方案，借此说明了工艺在生产 过程中的重要性。本人的设计的主要内容是：进行了机床总体布局设计；对机床的进给和传 动部分进行了设计；结合实例，介绍了夹具设计方法；通过此设计，本机床完全能满足设计 要求，与传统的机床相比，本机床具有自动化程度高，生产率高，精度高等优点。 关键词：组合机床；钻头；夹具设计；液压定位,手动夹紧. Abstract Application of combined high-volume machining parts, high efficiency, high productivity is the development direction of machining. The graduation project is entitled " Crankcase front end of drill hole." The combined machine tool needs to be achieved while drilling four holes. Making process in the process, conducted by volume ends face milling processing program, and to seek the best technology solutions, which illustrates the process in the importance of the production process. The main elements of my design are: the general layout for a machine tool design; on the machine feed and transmission parts of the design; Integration for the fixture design; With this design, this machine can meet the design requirements, and the traditional compared to the machine, this machine has high automation, high productivity and high precision. Keywords: milling head; Bit;fixture design; Hydraulic, manual clamping. 1 目 录 第一章 绪论………………………………………………………………………………4 1.1 组合机床的概论……………………………………………………………………4 1.2 组合机床的发展现状与趋势………………………………………………………4 1.3 机床设计的目的、内容、要求……………………………………………………5 1.3.1 设计的目的………………………………………………………………………5 1.3.2 设计内容…………………………………………………………………………5 1.3.3 设计要求…………………………………………………………………………6 1.4 机床的设计步骤……………………………………………………………………6 1.4.1 调查研究…………………………………………………………………………6 1.4.2 拟定方案…………………………………………………………………………6 1.4.3 工作图设计………………………………………………………………………7 第二章 零件分析 2.1 零件的结构特点及其技术要求…………………………………………………7 2.1.1 零件结构特点……………………………………………………………………
