摘 要

毕业设计是培养我们实际工作能力的最后一个重要实践性学习环节，它不但是对我们三年来的学习与实践是一个很好的总结和考验，也是为以后从事专业技术工作做个强而有力的铺垫。

本次我的设计题目是组合件，在设计之前对此类零件没有太多了解，经过多次调查研究和指导老师的细心指导下,使我能够很好的完成这次设计。此次设计不但培养了我们综合运用所学知识分析和解决本专业一般技术问题的能力，而且也进一步巩固扩大和深化了我们所学的基本理论、基本知识和基本操作技能，同时也培养了我们树立正确的设计思想和生产观念、经济观念、全局观念，养成了理论联系实际和严谨的工作作风，培养我们掌握机械加工的一般工艺规程和方法，独立正确的使用技术文献资料和正确的表达自己设计思想的能力。

首先，我积极地查阅相关资料，对零件图进行了仔细的研究，了解了现场工作情况，然后，向老师认真的请教了加工工艺过程及方法等技术性问题，为自己进行毕业设计做好准备。通过以上学习，使我了解了本组零件的结构，生产纲领和生产条件，并确定其重要加工表面。老师的辅导与分析，让我能综合运用所学过的理论知识和方法，正确地制定一个零件的机械加工工艺规程，从而保证零件的加工质量、生产率和经济性；能较熟练地使用有关的手册，图表资料及技术参考书，也能够较熟练应用工艺计算的方法，正确地进行工艺计算，熟练掌握一般零件的数控编程方法，机床的操作以及零件的数控加工。最后说明书来阐述了关于零件的有关内容及加工工艺过程等几个重要方面，认真地完成了整个设计的过程。

在此，对给予我大力支持和热情帮助的老师们表示忠心的感谢。由于个人能力有限，经验欠缺，因此，文中错误，不妥之处在所难免，恳请各位领导及老师批评指正。

Abstract

Abstract

Graduation design is the culture we have practical work last important practical learning link, it not only to our three years of study and practice is a good summary and the test, is engaged in professional and technical work after a powerful matting.

This my design topic is assemblies, in the design of such parts before without much understanding, after many investigation and guiding teacher's guidance, can make me very good finish this design. This design not only cultivate our comprehensive knowledge learned analysis and solve this major general technical problems, but also the ability to expand and deepen the further consolidate the basic theory, we have the basic knowledge and basic skills, but also cultivate we set up the correct design ideas and production concept, economic ideas, global idea, has formed the theory with practice and the rigorous work style, cultivate our master mechanical processing general procedure and method, independent proper use of the technical literature material and correct express their design thought ability.

First of all, I actively consulting relevant material, diagram of parts the careful research, understand the work, then, to the teacher carefully consulted the machining process and methods for their technical question, prepare graduation design. Through the study, make me understand the structure, the group parts production quota and production conditions, and determine its important processing surface. The teacher's guidance and analysis, let me have multiple utilizate all the theoretical knowledge and methods, correctly make a machining procedure, to ensure parts processing quality, productivity and efficiency; Can a skillfully using relevant manuals, chart material and technical reference books, also can very skilled application process calculation method, correctly to process calculation, master general parts CNC programming method, and the machine's operation and parts of the nc processing. Finally to manual expounded on parts related content and machining process and several other important aspects, and carefully has completed the design process.

Here, I would like to give me support and enthusiasm to help teachers to express our heartfelt gratitude. Due to personal ability is limited, lack of experience, therefore, the mistakes, improper in the one, ask leaders and teacher criticism and corrections.
