摘要
针对加工方式加工径向尺寸远大于轴向尺寸的大型金属密封圈工件时容易使其产生翘曲变形,而且工件正、反面跳动精度容易超差,同时也会造成表面粗糙度达不到要求的问题。通过分析该类工件的结构特点,设计了新的夹具与加工工艺。实践证明,新的夹具与加工工艺保证了工件精度。
When machining the large gaskets which radial dimension is much larger than axial dimension,it is easy to produce warpage and exceed the required run- out tolerances and surface roughness of the two surfaces of the gaskets. A new fixtrue and process is designed based on analysis of structure characteristics of this kind of gasket. It has been proved by practice that the new fixture and process guarantee the precision of the gasket.
