[0015] Beneficial effects of the present invention:

[0016] (1) The thrust ball cage bearing assembly equipment described in the present invention adopts a secondary separated ball loading method to prevent all steel balls from being simultaneously installed into the cage pocket holes by interference fit, which would cause the cage to deform due to stress and possibly crack the weakest crossbeam of the cage. The secondary separated press-fitting of steel balls into the ball pocket holes can provide a release space for the elastic deformation of the cage and relieve the stress on the crossbeam of the cage to ensure the integrity of the cage. The upper and lower structural designs of the ball pocket holes in the steel ball cage are asymmetrical. In order to simultaneously meet the assembly and the movement of the steel balls in the pocket holes, a 10° guide angle is designed in the ball loading direction of the ball pocket holes. The guide angle is connected to a 1mm thick buckle step, so that the steel balls can fall smoothly into the installation position and the movement of the steel balls can be accurately controlled.

[0017] (2) The thrust ball retainer bearing assembly equipment described in the present invention has a set structure. When the hydraulic cylinder is started to move downward, it will drive the second sliding rod to move downward and then rotate around the first sliding rod. The second sliding rod moves downward and then rotates around the first sliding rod to correct the ball pocket hole on the retainer to a specified position. The set structure drives the air bag to loosen the fixation of the retainer at the lower end of the round block when the hydraulic cylinder moves downward, so as to prepare for the subsequent rotation of the retainer.

[0018] (3) The thrust ball retainer bearing assembly equipment described in the present invention adopts a structure that drives the pressure plate to move downward when the pressure cylinder moves downward. The downward movement of the pressure plate presses the steel ball at the upper end of the retainer into the inside of the ball pocket hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Working principle: When the present invention is used, the controller is first used to control the servo motor 301 to intermittently rotate a quarter of a turn.

The first disc 304 is attached to the lower end of the second disc 305. An opening 3041 is provided inside the first disc 304 for unloading the assembled retaining frame 900. When the second disc 305 is intermittently rotated a quarter of a turn, the second hollow grooves 3052 are first rotated to the lower end of the silo 510.

When the retaining frame 900 rotates to the lower ends of the first cylinder 600 and the second cylinder 700 respectively, the steel balls will be loaded into the ball pocket holes 901. The secondary separation ball loading method is adopted to prevent all the steel balls from being loaded into the retaining frame 900 pocket holes with interference at the same time, and the retaining frame 900 is deformed by force, which may cause the weakest crossbeam of the retaining frame 900 to crack. The secondary interval pressing of the steel balls into the ball pocket holes 901 can provide space for the elastic deformation of the retaining frame 900, and at the same time relieve the stress level of the retaining frame crossbeam, thereby ensuring the integrity of the retaining frame 900. After the secondary separation and loading of the balls, the retaining frame 900 continues to rotate at intervals and will turn to the lower end of the pressure plate 802 to complete the pressing of the steel balls into the ball pocket hole 901.

[0041] When the servo motor 301 rotates intermittently for a quarter of a turn and drives the holder 900 to be corrected in the second hollow groove 3052 to move to the lower end of the round block 406, the arc block 504 drives the air bag 508 to expand under the extrusion force of the guide ring 503 to fix the holder 900. When the hydraulic cylinder 401 moves downward, the first inclined slider 501 moves downward, which drives the second inclined slider 502 to move downward. When the second inclined slider 502 moves downward, the guide ring 503 moves away from the arc block 504. The guide ring 503 is made of spring steel and has good deformation recovery ability. At this time, the spring 506 resets and drives the piston 505 to move away from the airbag 508. When the hydraulic cylinder 401 moves upward, the guide ring 503 resets and drives the arc block 504 to move inward. The compressed air enters the airbag 508 to limit the position of the corrected retaining frame 900. The structure is set up to drive the airbag 508 to loosen the fixation of the retaining frame 900 at the lower end of the round block 406 when the hydraulic cylinder 401 moves downward, so as to facilitate the subsequent preparation for the rotation of the retaining frame 900.

[0042] When the hydraulic cylinder 401 moves downward, it will also drive the connecting rod 801 to move downward. The downward movement of the connecting rod 801 will drive the pressure plate 802 to move downward. The downward movement of the pressure plate 802 will press the steel ball at the upper end of the retaining frame 900 into the inside of the ball pocket hole 901. The structure is set up so that when the hydraulic cylinder 401 moves downward, it will also drive the pressure plate 802 to move downward. The downward movement of the pressure plate 802 will press the steel ball at the upper end of the retaining frame 900 into the inside of the ball pocket hole 901.
