南湖学院 毕业论文（设计） 题 目: 基于Pro/Engineer的挖掘机工作装置设计 作 者 届 别 系 别 机械与电子工程系 专 业 机械设计制造及其自动化 指导教师 职 称 完成时间  摘 要 随着我国基础设施建设的深入和在建设中挖掘机的广泛应用，发展满足我国国情所需要的挖掘机是十分必要的。本设计主要对挖掘机工作装置的连杆机构、斗杆等进行计算机辅助设计，依据使用过程中的功能和运动性能要求，对其结构进行参数化设计，以便今后能根据用户的使用要求及时对挖掘机工作装置中运动部件的形状和尺寸进行更改。同时，设计应能根据用户使用要求对其中的一些部件进行替换装配，并进行初步的运动分析，使所设计的挖掘机摇臂机构能实现所需要的传动要求，从而达到快速设计产品的要求。主要采用计算机辅助设计行业内非常著名的Pro/Engineer软件来对挖掘机工作装置进行三维参数化设计。 关键词：Pro/Engineer；挖掘机；工作装置；参数化设计  ABSTRACT With Chinas industries continue to develop and die industry is also becoming increasingly important. Based on the Cover of the stamping process and the deep drawing process, Comparative analysis of the process of forming three different stamping process (single processes, complex processes and continuous processes) confirm completion of a composite model blanking, drawing processes and punching process. On the cover of the cold stamping process, right after the Cover of the mass production, quality components, and the use of structural components of the analysis, research, in line with lower performance prerequisite to the identification of stampings, Stamping method used to complete the processing components, and a brief analysis of the blank shape, size, layout, the Conference Board, the number of Drawing, stamping processes in nature, number and sequence determination. For the process, the center of pressure, the die size and the tolerance of the calculation, design mold. Also analyzes the mold of the main components (such as punch and die and dump devices, drawing punch, slates, Punch plate, etc.) design and manufacturing, stamping equipment selection, punch-gap adjustment and establishment of a vital parts machining process. Die requirements set out a detailed list of parts, and gives a reasonable assembly. By fully utilizing modern manufacturing technology to mold trad
