摇臂轴座零件图A3
摘要
我们国家现在机械化发展的很快，所以需要对现有的技术，装备进行提升跟改造，并且还要将一些新的材料，新的能源，新的技术等使用到生产里面去。专用夹具就是其中一个重要的组成部分。
这篇设计的零件是摇臂轴座，按照要求需要对其进行工艺和铣夹具的设计。随着非标零件越来越多，以及考虑现实生产的需求，通用夹具是满足不了，并且使用通用夹具对产品进行装夹，效率比较差，劳动强度也很强，生产产品质量不好，并且还要进行划线。
本文在完成工艺规程设计的基础上，还对零件图50下端面进行了铣床专用夹具设计。专用夹具的设计既要确定定位方案，夹紧方案，还有对刀方案，设计出夹具体，分析生产精度等。由此生产出来的零件，其效率较高，成本少。

Abstract
Our country is now developing mechanizedvery quickly, sowe need to upgrade and renovate existing technologies and equipment, and also use some new materials, new energy, new technologies, etc. into production. Special fixtures are an important part of this.
The part designed in this paper is a rocker shaft seat,which is designed for the process and milling fixture as required. With more and more non-standard parts, and considering the needs of real production, universal fixtures can not meet, and the use of universal fixtures to clamp the product, the efficiency is relatively poor, the labor intensity is alsovery strong, the quality of the production products is not good, and Also underline.
On the basis of the design of the process specification, the special fixture design of the milling machine is also carried out on the lower end of the part drawing 50. The design of the special fixture is to determine the positioning scheme, the clamping scheme, and the tool setting scheme, design the clip specific, and analyze the production precision. The parts thus produced are more efficient and less costly.
Keywords: special fixture, rocker shaft seat, process, milling fixture, 50 lower end
