摘要

机械制造工业是在我国国民经济中起着极其重要作用的基础工业。近年来，随着现代科学技术的进步，机械制造工业的面貌发生了深刻的变化，呈现出激烈的国际性竞争的高速发展态势。

机械工业的高速发展，对高职院校培养工程技术人才提出了新的更高的要求。机械制造工艺在机械制造工业中为国民经济各部门和自身的技术进步提供先进的技术、装备，在国民经济中具有重要的地位和作用，应用于各个领域。机械工业的规模和技术水平是衡量国家科技水平和经济实力的重要标志。

机械制造工艺知识具有很强的实践性。因此，本课题的内容重视的是零件的作用，结构和工艺过程的拟制及夹具设计和加工方案的确定。即通过设计及车间调研来更好的体会，加深理解。本课题给出的仅是零件图，真正的设计与加工必须在不断的实践、理论循环中总结。

在研究本课题过程中通过各种渠道搜集了一些与本课题相关的资料。例如：图书查阅、上网搜集、请教老师及和同学之间的讨论。本课题的重点零件的工艺分析和工艺规程制定

关键词：机电一体化，传动轴，零件，刚度，强度

ABSTRACT

Mechanical manufacturing industry in the national economy in China is plays an important role in the basic industry.In recent years,along with the development of modern science and technology progress,machinery manufacturing industry,great changes have taken place,the fierce international competition of high-speed development trend.

The rapid development of industry,mechanical engineering in higher vocational colleges are put forward new talents of higher requirements. Mechanical manufacturing process in mechanical manufacturing industry for national economic sectors and its technical progress of advanced technology and equipment provided in the national economy,and has an important position and role,applied in various fields.Mechanical industrial scale and technology level of national science and technology level and measure is an important symbol of economic strength.

Mechanical manufacturing process knowledge is strong practicality. Therefore,the importance of this topic is part of the content,structure and process of artificial and fixture design and processing of the scheme. Through the investigation and design and workshop,better to deepen understanding.This topic is only part of the design and fabrication,in practice,and to summarize cycle theory.

This topic in the research process through various channels and collected the data of topic.Example:the Internet access,collect books, consult teachers and classmates and the discussion between.The key parts of the subject of process analysis and procedure

Keywords：mechanical and electrical integration，Shaft,parts,stiffness, strength
