The outer ring of the outer spherical bearing is consistent with the outer ring of the outer spherical bearing, and the connecting branch pipe 401 is connected at intervals on the annular pipeline 4. The connecting branch pipe 401 is penetrated and matched with the pneumatic chuck 2, and the other end of the connecting branch pipe 401 is clamped and fastened with the blowing seat 204. The pneumatic chuck 2 of this structure is an existing pneumatic chuck, which is pneumatically driven to move the clamp seat 201 to realize the clamping treatment of the outer spherical bearing by the rolling wheel 203, and when the outer spherical bearing rotates, the outer ring of the outer spherical bearing is rolled. The rolling wheel 203 can be detachably designed relative to the clamp seat 201 through the connecting branch pipe 401, so that rolling wheels 203 of different sizes can be replaced according to different types of outer spherical bearings. The outer cover of the outer ring rolling device body 1 is provided with a protective heat preservation cover 5, and a rotating fixed cover is provided in the protective heat preservation cover 5. The positioning member 6 is rotatably connected with a positioning sleeve 602 in the rotating positioning member 6, and a telescopic hydraulic cylinder 7 is fixed through the positioning sleeve 602. An inclined surface structure is arranged on one side of the upper end of the protective heat-insulating cover 5, and a through hole is provided on the inclined surface of the protective heat-insulating cover 5, and an opening and closing door 502 is hingedly installed at the inclined surface opening of the protective heat-insulating cover 5, and the other side of the protective heat-insulating cover 5 is an opening structure, and a positioning cover 501 is screwed and fixed to the opening of the protective heat-insulating cover 5 after being clamped, and the positioning cover 501 is sealed and screwed and fixed to the pneumatic chuck 2. This structure performs heat preservation treatment for the processing area through the protective heat-insulating cover 5 to reduce temperature loss. The protective heat-insulating cover 5 is detachably fixed relative to the pneumatic chuck 2 through the positioning cover 501, which is easy to maintain the pneumatic chuck 2, and the positioning sleeve 602 is close to the opening. A movable pressure rod 601 is welded and fixed on one side of the closing door 502, and the movable pressure rod 601 contacts and cooperates with the opening and closing door 502. When the positioning sleeve 602 is rotated by the positioning of the rotating positioning member 6, the rotating positioning seat 701 is driven by the telescopic hydraulic cylinder 7 to move, so that the outer spherical bearing is loaded and unloaded by the rotating positioning seat 701. The positioning sleeve 602 is driven by the stepper motor to reciprocate 90° by the positioning of the rotating positioning member 6. When the positioning sleeve 602 rotates, the movable pressure rod 601 moves synchronously. After the movable pressure rod 601 contacts the opening and closing door 502, it pushes the opening and closing door 502 to open. The opening and closing door 502 is an existing automatic closing door with spring damping. After the thrust of the movable pressure rod 601 on the opening and closing door 502 disappears,The opening and closing door 502 can be closed automatically. If the air pressure in the protective heat preservation cover 5 increases, the pressure is released through the opening and closing door 502. A rotating positioning seat 701 is rotatably installed at the movable end of the telescopic hydraulic cylinder 7, and the rotating positioning seat 701 corresponds to the position of the rotating positioning shaft 3. A rotating drive motor 301 is installed at one end of the rotating positioning shaft 3 through a coupling, and a special-shaped connecting hole 302 is provided at the other end of the rotating positioning shaft 3. This structure drives the rotating positioning shaft 3 to rotate by the rotating drive motor 301, so as to realize the rotation of the outer spherical bearing, so that the outer ring of the outer spherical bearing can be evenly rolled. A connecting rod 702 of an integrated structure is provided at the end of the rotating positioning seat 701, and the connecting rod 702 is tightly plugged with the special-shaped connecting hole 302. After the outer spherical bearing is fixed after loading by the telescopic hydraulic cylinder 7, this structure can send the outer spherical bearing into the pneumatic chuck 2, and with the cooperation of the connecting rod 702 and the special-shaped connecting hole 302, the outer spherical bearing can rotate smoothly. ,

[0019] Working principle: When using the outer ring rolling device for processing outer spherical bearings, first, the positioning sleeve 602 is driven by the stepper motor to reciprocate 90° through the positioning of the rotary positioning member 6. When the telescopic hydraulic cylinder 7 is set vertically, the positioning sleeve 602 pushes the opening and closing door 502 through the movable pressure rod 601 to open the protective heat preservation cover 5, and the outer spherical bearing is loaded and unloaded. The outer spherical bearing is sleeved on the rotary positioning seat 701 for positioning, and then the telescopic hydraulic cylinder 7 is rotated to a horizontal position. Then the telescopic hydraulic cylinder 7 is started to extend the telescopic hydraulic cylinder 7, and the connecting rod 702 is inserted into the special-shaped connecting hole 302, so that the outer spherical bearing is firmly fixed between the rotary positioning shaft 3 and the rotary positioning seat 701. The pneumatic chuck 2 is driven by pneumatic clamping to make the fixture seat 201 drive the fixed seat 202 to move, so that The rolling wheel 203 clamps the outer spherical bearing, and the blowing seat 204 moves with the clamp seat 201 and approaches the outer spherical bearing, and then the rotary drive motor 301 is started, so that the outer spherical bearing is rotated by the clamping of the rotating positioning shaft 3 and the rotating positioning seat 701, and the outer ring of the outer spherical bearing is rolled by the rolling wheel 203 during the rotation. At the same time, the annular pipeline 4 provides a heat source for the blowing seat 204 through the connecting branch pipe 401 under the action of the heat pump, so that the surface temperature of the outer spherical bearing is consistent, ensuring the outer ring rolling effect. The protective insulation cover 5 is fixed to the pneumatic chuck 2 through the positioning cover 501, and the temperature loss is reduced by the protective insulation cover 5. If the air pressure in the protective insulation cover 5 increases, the pressure relief treatment is performed through the opening and closing door 502, so that the outer ring rolling device body 1 can be used more efficiently, thereby completing a series of tasks.
