毕业设计（论文）-差速器壳加工工艺及夹具计（全套图纸）.doc

摘 要随着社会的发展，汽车在生产和生活中的越来越广泛，差速器是汽车中的重要部件，其壳体的结构及加工精度直接影响差速器的正常工作，因此研究差速器的加工方法和工艺的编制是十分必要和有意义的。本次设计主要内容有：差速器的工作原理结构分析，差速器壳体的工艺编制，夹具的设计及加工中对定位基准的选择，工序和工装设计中切削用量，夹紧力的计算等。机床夹具的种类很多，其中，使用范围最广的通用夹具，规格尺寸多已标准化，并且有专业的工厂进行生产。而广泛用于批量生产，专为某工件加工工序服务的专用夹具，则需要各制造厂根据工件加工工艺自行设计制造。本设计的主要内容是设计镗孔夹具和钻孔夹具。关键词：差速器，壳体，工艺规程，夹具设计全套图纸，加153893706AbstractAlong with social development motor vehicle production and life in anincreasingly wide differential device is an important vehicle componentsand its interior structure and processing precision differential devicedirectly affect the normal work study differential device case processingmethods and techniques of preparation is necessary and meaningful.
