毕业设计（论文）变速器换挡叉的机械加工工艺与夹具设计院 别控制工程学院专业名称过程装备与控制工程班级学号学生指导老师2013 年 6 月 13 日变速器换挡叉的机械加工工艺与夹具设计摘 要变速器换档叉位于主轴箱。主要作用是传递扭矩，使变速器获得换档的动力。优点是可以从一种速度直接变到另一种速度,而不需要经过中间的一系列,因此变速很方便;其缺点是比较复杂。本课题根据调查讨论所提供的数据和有关技术资料，运用机械制造技术理论等相关专业知识对变速器换挡叉零件的作用和工艺进行了分析和计算，并对该换挡叉的加工工艺以与其夹具进行了优化设计。本论文制定了变速器换挡叉的工艺规程方案，拟定了夹具设计方案并完成了其第五工序的夹具结构设计。最后通过使用 AUTOCAD 绘制装配图和零部件图.关键词：换档叉；工艺；夹具Transmission shift fork mechanical processing technology and fixture designAuthor：Bao Lisheng Tutor：Ma LianjieAbstractThe transmission shift fork is located in the spindle box. The main function is to transfer torque, power transmission gain shift. The advantages can be changed directly to another speed from a speed, without the need to go through a series of intermediate, so the transmission is very convenient; the disadvantage is the relatively complex. This topic provides according to the investigation data and relevant technical data, application and process knowledge of mechanical manufacturing technology and other related professional theory of transmission shifting fork of the parts are analyzed and calculated, and the processing technology of the shifting fork and the jig design is optimized. This paper developed a process scheme of transmission shift fork, the design of fixture and the fixture structure design of the fifth. Finally, by using the AUTOCAD assembly drawing and parts drawing.Keywords: shift fork; technology; fixture目 录目 录 III1 绪论......................................................................................
