摘要
这次专业设计是专业的一个十分重要的学习环节,是对入学以来所学的机械方面的知识进行了一次全面的检查、巩固和提高。这次课程设计是应用所学基础理论、专业知识与技能去分析和解决生产实际问题的一次综合训练。把所学的知识能够综合运用到实际零件的加工中。通过本次设计使我巩固了已学的知识,加深了印象,使自己能够运用所学的机械加工知识解决一些具体的问题。
此次课程设计涉及的知识面有夹具设计、零件安装、加工工艺、数值计算、刀具的性能、测量技术、CAD制图外还涉及到金属材料、公差配合及加工设备等多方面的知识。通过这次课程设计我发现了自己还有许多知识还没有掌握牢固。但更多的是通过这次设计使我提高、巩固、扩大了自己所学到的理论知识与技能,提高自己设计计算、制图、编写技术文件的能力‘学会正确使用技术资料、标准、手册等工具书’并在这次设计中培养了我对机械设计的独立工作能力、初步树立了正确的实际思想,掌握了一定的机械加工设计方法步骤和思路为以后的学习和设计工作打下了良好的基础。同时,也使我体会到了老师平时对我们的谆谆教导、用心良苦。由于本人水平有限,设计还有许多不足之处,希望时老师给予批评和指正!

ABSTRACT
The professional design is one of the important link of the study, it is learned since admission knowledge of mechanical conducted prehensive examination, consolidate and enhance. This course is designed to apply their basic theory and specialty knowledge and skills to analyze and solve practical problems of production. Combine the knowledge to use to the actual machining. Through the design that I have learned knowledge consolidated, deepen the impression, make oneself can use some specific knowledge of mechanical processing.
This course design involves knowledge have clamp design, installation, processing, parts of numerical calculation, tools and measuring technology, the properties of the CAD drawing was involved in metal materials, tolerance and processing equipment, this course design, I found the oneself still have many knowledge has not mastered the firm. But more and more are through this design makes me improve, consolidate and expand their knowledge to the theoretical knowledge and skills, improve their design calculation, drawings, writing ability of technical documents to correctly use the technical data ", standard, manual tool in the design of "and I trained on mechanical design of the ability to work independently, set up the correct actual preliminary thoughts, grasped certain mechanical processing design methods and
