毕业设计（论文）-柴油机的凸轮轴零件进行工艺工装设计.doc.docVIP

摘 要 此次毕业设计是针对柴油机的凸轮轴零件进行工艺设计以及工装设计。 凸轮轴是发动机中的一个重要组成部件，由于其结构特性，对材料的要求和加工的精度要求较高，如端面加工、中心孔加工以及凸轮的加工等。对于此次工艺过程的制作，我查阅了很多的相关资料，尽力做到表达清晰、语言简练。本次的设计任务能使我巩固大量有关于机械方面特别是机械制造方面的专业知识，并且从曾经学习过的知识当中又获得了新的东西，同时也学会了查阅文献，使用相关机械类专用手册如《机床夹具设计手册》、《金属机械加工工艺人员手册》等，进一步增进了我对现成知识、经验及标准参数的使用和运用以及理解的能力。在夹具部分我使用了液压传动机构作为夹紧机构，这样做的好处是可以减少时间，减轻工人的劳动量，能够提高加工的效率以及加工精度，提高自动化率，提高生产的安全性，为企业的生产带来更多效益。由于本人的水平以及经验有限，在此次设计中难免会存有一些问题待改正或改进，欢迎各位读者对存在的问题进行批评和指正。 关键词：凸轮轴 工艺 夹具 液压传动 Machining process and fixture design of camshaft Abstract My Graduation project is making the process design and process equipment design about camshaft of the diesel engine. Camshaft is one of the most important machine replacement parts, it needs the high quality materials and the high precision machining for its special nature of the structure, such as machining end face, center hole and the cams. I search many of the relevant information and literature when Im doing this project, I tried my best to make my expression cleared and use the simple words. I this project I reinforced my professional knowledge about the Machinery Manufacturing, and I learned something new from the knowledge that I have learned, at the same time I learned how to search the literature and how to use the manual about Machinery Manufacturing such as Manual Fixture Design and Processing Personnels Manual Of Metal Processing Technology and so on, it can prove our ability of using the knowledge, experience and standard parameters. In the fixture design part I choose hydraulic transmission mechanism as the gripper mechanism. it can reduce the processing time, reduce labor of workers, also can improve processing efficiency, processing precision, improve the rate of automation and more safety, and it can brings more profit to the company. Because of my limited experience and level, it must be some problems in my project to be corrected or improved, welcome every readers to criticize and correct the problems. Thank you. Keyword:
