 本科毕业设计论文 题 目 空压机吸气阀盖头加工工艺编程及夹具设计 姓 名 专 业 机械设计制造及其自动化 新乡学院机械工程学院 2018年4月 摘 要 本文是对空气机吸气阀盖头零件加工应用及加工的工艺性分析，主要包括对零件图的分析、毛坯的选择、零件的装夹、工艺路线的制订、刀具的选择、切削用量的确定、加工工艺文件的填写。选择正确的加工方法，设计合理的加工工艺过程。此外还对空气机吸气阀盖头零件加工设计了专用夹具. 机床夹具的种类很多，其中，使用范围最广的通用夹具，规格尺寸多已标准化，并且有专业的工厂进行生产。而广泛用于批量生产，专为某工件加工工序服务的专用夹具，则需要各制造厂根据工件加工工艺自行设计制造。本设计的主要内容是设计。 全套图纸加153893706 Abstract The high efficiency, the precision work are one of numerical control engine bed processing most main characteristics. Using the numerical control engine bed processing, its product processing quality uniformity is good, the processing precision and the efficiency outdo compared to the ordinary engine bed very much, especially when outline not rule, complex curve or curved surface, multi-craft recombine processing and high accuracy request product processing, its merit is the traditional engine bed is unable to compare. This topic to the opposite sex body, the complex curve, the multi-craft recombine processing carries on the exploration, designs three practical and feasible technical processes and the craft equipment. In the product processing process, the work piece appears in jig localization and the clamp specially importantly. Must act according to six localizations to carry on the reasonable localization to the product, owes the localization, locates completely crosses the localization all to have to act according to the actual production process decision. The jig covered from has processed clamps the equipment to the assembly nearly all operating process one kind of attire. Because the massive processing operation needs to install clamps, the jig design changes can it be that the constant weight in the manufacture system to want, it affects the processing quality directly, the productivity and the production cost. This article through the analysis support components, the air compressor snifting valve lid as well as the suppor
