Press fitting die for bearing outer diameter check ring

The utility model discloses a bearing outer diameter check ring press-fitting die, and relates to the technical field of bearing assembly. The die comprises an upper die plate and a lower die plate which are coaxially arranged, a plurality of grooves are evenly distributed in the outer edge of the top face of the lower die plate in the circumferential direction, and ring expanding assemblies are movably matched with the interiors of the grooves; the inclined rod is integrally formed at one end of the cross rod and obliquely extends towards one side of the lower mold disc, the vertical rod is integrally formed above the other end of the cross rod, and the cross rod is slidably sleeved with a blocking column in the vertical direction. When the bearing check ring mounting device is used for mounting a check ring on a bearing, the overall operation is simple and convenient, the production efficiency is high, the labor intensity can be effectively reduced, the overall operation safety is good, meanwhile, the beari
