北京理工大学珠海学院 2020 届本科生毕业设计活塞式空压机部件加工工艺研发-活塞加工及夹具设计 工余量、计算工序时间等。根据工序镗销孔设计了一套镗销孔专用夹具以确保加工精度。其中包含选取定位元件、夹紧装置、标准件和夹具体的设计。最后，通过分析定位误差和计算夹紧力来验证夹具的合理性。关键词：活塞；工艺路线；工序；定位；夹具设计北京理工大学珠海学院 2020 届本科生毕业设计北京理工大学珠海学院 2020 届本科生毕业设计Piston air compressor parts processing technology development-piston processing and fixture designAbstractBy analyzing the development background of the piston, the development status of the fixtures at home and abroad, and the structure of the parts, a processing route and a set of production plans for the piston are designed, which mainly include: selecting the blank material, determining the blank manufacturing method, selecting the rough and fine benchmark Draw up reasonable process lines, determine the machining allowance, determine the machining allowance for each procedure, calculate the procedure time, etc. A set of special fixtures for boring pin holes is designed according to the process of boring pin holes to ensure machining accuracy. It includes the specific design of selected positioning components, clamping devices, standard parts and clamps. Finally, the rationality of the fixture is verified by analyzing positioning errors and calculating clamping force.Keywords: Piston; process route; process; positioning; fixture design北京理工大学珠海学院 2020 届本科生毕业设计目录1.前言........................................................................11.1 研究背景和意义...............................................................11.2 国内外发展研究现状...........................................................12.活塞的工艺分析..............................................................22.1 活塞的作...
