设计简介
摘 要
机械制造业在中国产业的地位相当于基石，有这个基石，大到国家重要机械制造产业，小到平常生活机械产品，可以说现代机械制造业离不开机械加工过程，随之而来的是机床的不断更新和加工技术不断优化。拨叉用途广泛，变速器产品中零部件之一，批量生产拨叉零件，也是间接为国家制造业提供助力，并进行拨叉夹具设计，其主要内容包括零件的用途和作用，分析零件图尺寸精度要求等技术要求；分析零件工艺规程；设计零件加工工艺路线，以此为基础，选择其中一道工序夹具设计，批量生产拨叉。
关键词：拨叉 工艺 工序 夹具
Abstract
The position of machinery manufacturing industry in China is equivalent to the cornerstone. With this cornerstone, it can be said that modern machinery manufacturing industry can not be separated from the mechanical processing process, which is accompanied by the continuous updating of machine tools and the continuous optimization of processing technology.
The fork is widely used, one of the parts in engine products, mass production of fork parts is also indirect to the national manufacturing industry, and the fork jig design is carried out. Its main contents include the use and function of parts, analysis of the technical requirements such as dimensional accuracy requirements of parts drawings, analysis of parts process regulations, design of parts processing technology route, based on which to select one of them. One process fixture design, batch production fork.
Key words: fork; technology; process; fixture
