Tianjin University of Technology and Education 毕 业 设 计 专 业 机械制造工艺教育 班级学号 机制0512-16 学生姓名： 李 庆 指导教师： 尚德香 副教授 二〇一〇 年 六 月 天津职业技术师范大学本科生毕业论文 油缸体工艺规程及钻径向孔通用可调夹具设计 The technological design of the fuel tank body and drill bore general-purpose adjustable fixture designing 专业班级：机制0512班 学生姓名：李 庆 指导教师：尚德香 副教授 系 别：机械工程学院 2010年6月 摘 要 本次设计主要是对油缸体编制加工工艺规程并设计钻径向孔通用可调夹具。同时涉及到了进行夹具设计必需的毛坯选择、加工余量确定、切削刀具、机床选择及机动时间计算机等方面知识。本次设计内容包括两部分；首先是对油缸体零件的工艺分析，其次是针对油缸体零件的钻径向孔工序进行夹具体设计。本设计所选资料注意到贯彻必威体育精装版国家标准及部分标准。 本次设计是根据生产纲领为成批量，年产量800件左右设计的。设计中，考虑到成批生产，在加工过程中，为了保证被加工孔对其定位基准和尺寸精度和位置精度的要求，同时提高效率，对油缸体的钻径向孔工序进行夹具设计。设计采用长V型块定位，导向支架的布置形式采用双面单导向的形式，和将夹紧螺母设计在顶面的方式以减轻工人的劳动强度，节省辅助时间，提高生产率。 关键词：毕业设计；零件工艺规程设计；工序设计；夹具设计 ABSTRACT This design mainly is draw up to process the craft rules distance to combine a design to drill radial bore general-purpose adjustable fixture towards fuel tank body. Involve in the meantime to carry on an essential semi-finished product choice of the tongs design,process an amount of remaining assurance,slice to pare knife to have,aspect knowledges such as the tool machine choice and mobile time calculator etc.. This design contents includes two parts;the first parts of the fuel tank of the process analysis, followed by body parts for tanks drill radial bore design process for specific folders. Noted that the design selected information and implement national standards and some of the latest standards. The design is based on the Program for the production of bulk into an annual output of about 800 design. Design, taking into account the large number of production, during processing, in order to ensure processing benchmark hole location and size of its precision and accuracy requirements of position, at the same time improve the efficiency of the fuel tank body to carry out drill radial bore fixture design process. The design of a long V-block positioning, the layout-oriented form of stents used in the form of double-sided single-oriented, and the
