减速器机盖加工工艺与顶面孔钻夹具设计学院名称： 机械工程学院 专业：机械设计制造与其自动化班级：11 机制 1 学号：11321108 姓名： 颖 超指导老师： 何 庆 指导老师职称：教 授 二〇一五 年 五 月 本 科 毕 业 设 计 （ 论 文 ）减速器机盖加工工艺与顶面孔钻夹具设计摘 要：蜗杆减速器箱体零件是箱体类零件的一种。它把减速器箱体中的轴和齿轮等有关零件和机构联接为一整体，使这些齿轮等零件和机构保持正确的相对位置，以便其上各个机构和零件能正确、协调一致地工作，减速器箱体的加工精度直接影响减速器的装配质量，进而影响机器的使用性能和寿命。因此讨论使用适合的夹具对该类型零件进行加工是一个值得深化探讨的问题。在本次设计中，对蜗杆减速器箱体机盖的加工工艺路线进行了编制和方案优选，对钻夹具的钻模板类型进行了深化讨论以使所加工零件易于装夹，计算了采纳一面两孔制的定位方法所引起的定位误差，从而论证了该套设计方案的可行性和经济性。关键词：蜗杆减速器，箱体，钻夹具，工艺The Design of Reducer’s Cover machining process and Design of Top Face Drill FixtureAbstract：Worm gear reducer box body parts is one of the box body parts. The shaft of the reducer housing and gear and related parts and joined into a whole, make these gear and other parts and kept the correct relative position, so that its various agencies and parts can correct, the coordinated work, reducer box directly influences the machining accuracy of gear reducer assembly quality, will affect the use of machine performance and service life. Therefore research using suitable fixture for processing of the types of parts was a problem worthy of in-depth discussion. In the design, processing technology route of worm reducer box machine cover compilation and scheme optimization, the drilling template type of drill jigs were studied in order to make the processing parts easy clamping, were calculated by using a two hole system caused by the positioning method of positioning e...
