基于摆动摇臂工艺及钻 Ø26mm 孔夹具设计摘要 机械加工行业作为一个传统而富有活力的行业，近几十年取得了突飞猛进的发展，在新经济时代，行业呈现新的发展趋势，由此对其它的质量,性能要求有了新的变化。现在的机械加工行业发生着结构性变化，工艺工装的设计与改良已成为企业生存和发展的必要条件,工艺工装的设计与改良直接影响加工产品的质量与性能。本文首先介绍了气门摇臂的加工方法和工艺分析，然后进行夹具设计。此次设计是对气门摇臂的加工工艺和夹具设计，其零件为铸件，具有体积小，零件结构简单的特点，由于面比孔容易加工，在制定工艺规程时，就应该先加工面，再以面为基准来加工其它。其中，各工序夹具都采用专用夹具，其机构设计简单，方便且能满足要求。第一我们对产品(工件)的进行全面分析，确定了产品(工件)的毛坯设计，并附有生产工艺过程卡片以及工序卡片。第二我们对数控加工工艺分析主要是针对数控加工的内容，程序以及夹具的分析。关键词：摇臂；钻孔；夹具摇臂座工艺规程及夹具设计AbstractAs a traditional and dynamic industry, machining industry has made rapid development in recent decades. In the new economic era, the industry presents a new development trend, which requires new changes in other quality and performance requirements. Now the mechanical processing industry is undergoing structural changes, the design and improvement of process tooling has become a necessary condition for the survival and development of enterprises, the design and improvement of process tooling directly affects the quality and performance of processed products.This paper first introduces the processing method and process analysis of valve rocker arm, and then carries on the fixture design. This design is to the valve rocker arm processing technology and fixture design, its parts for the casting, with small volume, parts of the structure is simple, because the surface is easier to process than the hole, in the development of the process procedures, should first processing surface, then...
