3MZ1410B磨床磨削双列球轴承外圈双沟道的工艺改进

Technique Improvement of Outer Ring Double Raceway Grinding By Grinding Machine 3MZ1410B on Double Row Ball Bearings

分析了现有3MZ1410B单沟液压磨床分两次装夹定位磨削双列球轴承外圈双沟道存在的不足,即先磨出第一条沟,将外圈翻面再磨削第二条沟,因此,很难保证两沟道中心距尺寸的一致性,且产品安装合套率相应低下。利用现有设备,通过加装一套沟心距定位装置对原有加工工艺进行改进,实现了将两次装夹定位变为一次装夹定位磨削双列球轴承外圈双沟道,保证了沟心距尺寸的统一,提高了产品安装合套率和使用性能。

Based on current technique of 3MZ1410B single raceway hydraulic grinding machine for outer ring double raceway grinding by means of clamping twice, i.e. grinding one raceway, and then turning around for other raceway grinding, the conformity of raceway distance is difficult to be ensured in process and the matching rate is at the low level. In order to eliminate this shortcoming of current equipment, improve the technique by adding a raceway distance fixing device to realize one claming and ensure the conformity of raceway distance so as to improve the matching rate in assembly and at the same time improve the application performance of products.
