主轴套筒零件加工及夹具设计

Processing and Fixture Design of the Spindle Sleeve Parts

零件装夹变形直接影响零件的几何精度和尺寸精度,不合理的装夹方式即使在切削参数和加工设备都合理的情况下也会出现废品。文中以HT300铸铁主轴套筒零件为例,介绍了在标镗工序采用不同工装夹具加工,对零件加工精度的影响以及设计合理工装夹具在保证零件加工精度方面的重要性。

The parts clamping deformation directly affects the parts geometric accuracy and dimensional accuracy,unreasonable clamping way even in the cutting parameters and the processing equipment is reasonable will appear under the condition of waste. Cast iron HT300 spindle sleeve parts is taken as an example to introduce the different jigs and fixtures on the boring process processing,the impact on the precision parts processing,and reasonable design jigs and fixtures on the importance of precision of parts processing.
