夹具装配图
摘要
三周的机械制造课程设计即将结束,这三周把这学期学的机械制造技术基础的理论知识与实际的操作能力相结合,在魏老师的悉心指导下,我真正的掌握了基本的工艺规程设计和夹具设计理论,机床专用夹具等工艺装备的设计等。并学会了使用和查阅各种设计资料、手册、和国家标准等。最重要的是综合运用所学理论知识,解决现代实际工艺设计问题,巩固和加深了所学到的东西。并在设计过程中,学到了很多课堂上没有学到的东西。为我以后的工作打下坚实的基础。
Abstract
Three weeks of machinery manufacturing curriculum design coming to an end, this three-week semester of this school of mechanical manufacturing technology based on the theoretical knowledge and practical ability to combine operations, in Wei's well under the guidance of teachers, I truly grasp the basic process of order Fixture design and design theory, machine tools, such as technology and equipment for the fixture design. And learned how to use and access to all kinds of design information, manuals, and national standards. The most important thing is the integrated use of the theory of knowledge, the actual process design to solve modern problems, and to consolidate and deepen the learned things. And in the design process, learned a lot of class not to learn things. I work for the future and lay a solid foundation.
