丽水学院 毕业设计( 论文) ( 届) 题 目 小型铸件粗加工专业龙门铣设计 指导老师 院 别 班 级 学 号 0 姓 名 二〇 一三 年 五 月 二十一 日小型铸件粗加工专用龙门铣设计机械设计制造及其自动化 机自 091 廖鹏超 指导老师 叶晓平摘要本课题为解决机械粗加工时, 生产效率跟机床寿命之间的矛盾。根据生产效率的要求, 我们把原来有的普通龙门铣床简化结构, 使其在满足加工要求的下载后可任意编辑情况下, 尽可能的增加切削量和进给速度, 在很大程度上来缩短毛胚机械粗加工的时间, 同时也保证了机床的使用寿命, 尽可能的减少机床导轨的磨损和变形。综合运用所学的基本理论, 基本知识和相关的机械设计专业知识, 拟定小型龙门铣的总体方案, 解决加工难题。并绘制总装图和必要的零件图。关键词: 龙门铣Special gantry milling small cast rough designAbstractTo address this issue mechanical roughing, the production efficiency with the contradiction between the tool life. According to the requirements of efficiency, we had some general milling machine simplified structure, to meet the processing requirements in the case as far as possible the Zengjia cutting Volume and the feed rate to shorten the hair in Largely roughing the embryo Jixie time, but also ensure the service life of machine tools, machine tools as possible to reduce rail wear and deformation.Integrated use of the basic theory, basic knowledge and expertise related to mechanical design, develop small-scale gantry milling of the overall program to address the processing problems. And draw the necessary parts assembly diagrams and plans.Keywords: gantry milling下载后可任意编辑下载后可任意编辑目录第一章 绪论.........................................................21.1 讨论动机与目的...............................................21.2 课题主要讨论内容............................................3第二章微型龙门铣设计方向及达到的效果................................42.1 龙门铣的设计标准及加工零件范围.....................
