一种铁路轴承专用电磁无心内排液磨削夹具
本技术属于轴承制造领域,具体涉及一种铁路轴承专用电磁无心内排液磨削夹具。
技术介绍
铁路轴承在内沟道磨削过程中电磁无心夹具是在加工过程中有起到重要的支撑和定位作用,现主要采用的是单磁极式夹具,其中磁极是连接铁芯与工件的过渡件,也是与不同大小工件相配套的一个更换件,它起着导磁与支承工件端面的作用,除了能够较好的固定工件外,磁极的排冷却液、排屑结构在一定程度上影响着工件的磨削质量;为减少磁极与工件端面的接触面积和相互间的磨损,将磁极做成杯型,而在磨削工件过程中,冷却液和磨屑无法快速方便排出、并带走部分磨削热量,特别是磨削面积较大及磨加工内表面时(如磨两外滚道),冷却液和磨屑会较难排出,同时磨削热量不易散发,由此出现的后果主要有:1、冷却液的清洁度不易保证,当磨屑或杂质附在磁极或工件表面时会降低磨削精度;2、磨削热量逐渐聚集增多使工件表面产生磨削烧伤,这两方面有可能造成不必要的返工品或废品损失;因此,需要一种新型磨削夹具来解决现有轴承圈内沟道磨削过程中冷却液和磨屑无法及时排出早操工具表面精度 ...
