Device for installing bearing outer ring in part hole

The utility model relates to the technical field of bearing assembly, in particular to a device for installing a bearing outer ring in a part hole, which comprises a base, a pressing mechanism and a controller, the pressing mechanism is connected with the base and arranged above the base, and a pressing plate of the pressing mechanism is arranged to at least completely cover the part hole. The size of the pressing plate can at least cover the bearing outer ring, the pressing mechanism firstly applies preload to the bearing outer ring to enable the radial direction of the bearing outer ring to be perpendicular to the center line of the part hole, the bearing outer ring is in complete contact with the pressing plate, then the bearing is further extruded to be pressed into the part hole, in the whole extrusion process, the pressure on the bearing outer ring from the pressing plate is even, and the bearing outer ring is not prone to being damaged. According to the bearing pressing device, the bearing can be preve
