端盖零件的机械加工工艺规程及钻φ14孔夹具设计.pdf

辽宁工程技术大学 课 程 设 计 题 目：端盖零件的机械加工工艺规程及钻Φ14孔夹 具设计 班 级： 姓 名： 指导教师： 完成日期： 1 摘 要 机械制造工艺学课程设计是我们学完了大学的全部基础课、技术 基础课以及大部分专业课之后进行的.这是我们在进行毕业设计之前 对所学各课程的一次深入的综合性的总复习,也是一次理论联系实际 的训练,因此,它在我们四年的大学生活中占有重要的地位。 这次设计的是端盖，有零件图、毛坯图、装配图各一张，机械加 工工艺过程卡片和与所设计夹具对应那道工序的工序卡片各一张。首 先我们要熟悉零件，题目所给的零件是端盖。了解了端盖的作用，接 下来根据零件的性质和零件图上各端面的粗糙度确定毛坯的尺寸和 机械加工余量。然后我们再根据定位基准先确定精基准，后确定粗基 准，最后拟定端盖的工艺路线图，制定该工件的夹紧方案，画出夹具 装配图。 2 Abstract Abstract AAbbssttrraacctt Machinery Manufacturing Technology curriculum design is finished we learn all the basic course of the University, technology and the most basic course after the specialized, which is our graduation project before conducting the various courses of study by an in-depth comprehensive review of the total, is also a Theory with practical training, therefore, in our four years of university life occupy an important position. This is the cover design, parts map, rough map, one of the assembly, machining process with the card and the corresponding fixture designed by the procedures of the process of a card. First of all, we must familiar with the parts, the parts subject to the cover. Cover understanding of the role, followed in accordance with the nature of parts and components in the face of the map on the roughness of rough determine the size and mechanical Jiagongyuliang. According to another location and then we set the benchmark fine first base, established after the benchmark crude, finalizing the cover of the road map, the enactment of the workpiece clamping programme, to draw
