大连交通大学 2010 届本科生毕业设计（论文）1摘 要本课题来源于生产实践，充分利用所学的机械制图、机械设计及机械制造等课程，了解针对配气机构的特点，通过 CAD 软件，利用该软件制图功能，完成配气机构横臂零件铣钻孔夹具的设计。在课题的研究设计阶段，首先从众多的零件中选择一个作为设计夹具的零件。针对该零件的结构特点，制定该零件的加工工艺。其次要了解夹具的相关知识，结合零件的结构特点选择需要的夹具元件，设计出夹具的大体结构。机床夹具作为一种重要的工艺装备在机械制造工艺过程中起着十分重要的作用，它的设计不但要保证工件的加工质量，提高加工效率，降低成本，在操作维护中安全方便还要注意到夹具结构的标准化，夹具制造的精密化。为了保证夹具组装精度，需要学习了解工件定位原理。根据这些原理结合零件的结构特点确定零件在夹具中以一面两孔作为定位，计算夹具的定位精度与夹紧力保证零件在夹具上的加工精度。然后使用 CAD 绘图软件参考夹具设计手册绘制夹具元件的机械图，完成夹具的设计。关键词：CAD 加工工艺 工件定位 大连交通大学 2010 届本科生毕业设计（论文）2AbstractThis topic comes from production practice, make full use of what have learned mechanical drawing, mechanical design and mechanical manufacturing, and other programs, to understand the characteristics for the gas distribution sector, through the CAD software, the use of the software mapping function, complete with gas sector arm holes milling drilling fixture design. In the research projects in the design phase, first select from a number of parts as the design of a fixture parts. For that part of the structural characteristics of the development of the parts processing technology. Second, we must understand the fixture knowledge, combined with the structural features of components select the required fixture components, the general structure of fixture design. As an important fixture of the technology and equipment in the mechanical manufacturing process plays an important role, it is designed not only to ensure that the workpiece processing quality, improve processing efficiency, reduce costs, in the operation and maintenance of safe and convenient but also noted that Fixture structure of standardization, the precision of fixture manufacturing .In order to ensure the fixture assembly of precision, need to learn to understand principles of positioning the workpiece. Combination of components based on these principles to determine the structural characteristics of components in the fixture to one side two holes as the positioning of the positioning accuracy of calculation of fixture clamping force to ensure the parts with the fixture on the machining accuracy. And then use the CAD drawing software reference, Fixture Design Handbook, a mechanical fixture elements drawn map, complete fixture design.
