实体保持架钻铆钉孔模的改进 圆柱滚子轴承实体保持架上的铆钉孔原来是采用钻模加工,操作繁锁效率低,后改用右列图1所示定位块来固定保持架位置,并加用图2所示钻孔导向套,使其钻头旋转稳定,由原来钻孔位移超差±0.5毫米提高到±0.1毫米。 西北轴承厂 五车间 王迅 Solid cage drilling rivet hole mode improvement Cylindrical roller bearings Rivet holes on the solid cage originally used to die processing, cumbersome operation of the cumbersome, after the switch to the right column shown in Figure 1 to fix the positioning block holder position, And with the drilling guide sleeve shown in Figure 2, to make the drill rotation stable, from the original drilling displacement tolerance ± 0.5 mm increased to ± 0.1 mm.
