轴加工工艺及夹具设计说明书重点解读.doc

轴零件工艺工装设计 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，了解针对的特点，通过CAD软件，利用该软件制图功能，。在课题的研究设计阶段。针对零件的结构特点，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。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。  shaft parts of the fixture design Abstract This subject comes from the practical production, make full use of learning mechanical drawing, mechanical design and mechanical manufacturing course, understand according to the characteristics of shaft parts, through the CAD software, using the software mapping function, complete the design of spindle head parts process. 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 cylindrical?shaft 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.  Key
