文档介绍：摘要
二十一世纪的制造业面临着顾客需求驱动、不可预测、快速多变和来自全球
不断增加的市场竞争,而且竞争不断加剧。市场的不断变化要求制造系统加工的产
品品种能够快速变换以满足市场需求。近来的制造业发展表明,夹具能比较好的满
足上述要求并符合我国国情。作为制造系统重要组成部分的夹具设计部分,制造系
统对其提出了新的要求。夹具在机械加工起着重要的作用,它直接影响着机械加工
的质量,生产效率和成本,因此夹具设计是机械工艺准备和施工中的一项重要工作。
这篇毕业设计主要阐述的是一套关于电机座液压夹紧粗镗夹具的设计方法,这
种夹具主要应用于电机座的粗镗工序,通过这个夹具可以保证电机座粗镗后的加工
要求和达到提高生产效率的目的。
在说明书中,首先明确了设计任务并对夹具作了相关的阐述,接着根据电机座
的加工工序提出了镗床夹具的设计方法和理论,并依据这些方法和理论对夹具进行
设计和校核、验算。最后对夹具中某些典型或重要的零件进行了介绍和校核。这种
设计方法代表了镗模的一般设计过程,对其他夹具的设计工作也有一定的价值。
关键词:夹具、电机座、工序

Abstract
panies in the 21s' century will face unpredictable, high-frequency
market changes driven by petition. The continuous changes of market require a
rapid change of product varieties in order to meet the market demands. Recent surveys
have showed that fixture are the cornerstones of this new manufacturing paradigm. Fixture
is also suitable to our country. After reconfiguration manufacturing system puts new
requirements on fixture design, an ponent of the traditional manufacturing
system. Fixture is very important equipment in process of machine manufacturing because
it can directly affect the quality of products and productivity and cost. So fixture designing
is also a base portion in machine process.
This paper of graduation mainly presents a systematic approach for the design of
Electrical Block hydraulic upholding tool rough noise of drums .this upholding tool are
mainly used in the working procedure of Electrical Block hydraulic rough noise of drums .
It can plished the purpose what this fixture can be satisfy after Electrical Block
hydraulic upholding tool rough noise of drums produce demand and approach to improve
production efficiency.
First ,we define the design of assignment and represent something about fixture. The
next ,Accordingly to the processing of workpiece of motor ,we extract the
method and way of boring lathe of fixture. And then ,we practice into design the fixture
according to the method and way .After this design ,we take some canoni
