摘 要:
本设计的零件为惰轮轴，选用QT60-2钢。根据零件的形状、尺寸精度、生产的经济效益等各方面的详细分析其加工工艺，多采用专用机床加工。通过对零件的分析，此轴要求精度高，工序适当集中，要求光滑，所以选用工具和尺寸要准。最后对零件进行校核。以便达到零件精度的要求。
关键词：夹具、校核、
Abstract :
The design of the axle components are inert choose QT60-2 steel. According to parts of shape, size precision, production and other economic benefits of the detailed analysis of its manufacturing processes, the use of dedicated processing machine. Part of the analysis, accuracy of this axis, the appropriate concentration processes require smooth, and use tools to prospective size. Finally, the parts are checked. To meet the requirements of precision parts.
Keywords : Fixture, Verification,
