[0002] Automotive bearings are core supporting components in automotive transmission systems, ensuring vehicle performance, safety, and comfort. They are indispensable key components in modern automobiles. During the production of automotive bearings, they are typically moved by grippers.

[0003] However, in existing equipment, the outer surface of the bearing is relatively smooth. When the gripper moves, the bearing is prone to fall off due to insufficient friction, causing damage. Therefore, it is particularly necessary to design an auxiliary tooling for processing automotive bearings to solve the above problems. Summary of the Invention

The upper surface of the L-shaped connecting column has a snap-fit ​​hole, and the inside of the L-shaped connecting column has a sliding groove. A second threaded rod is rotatably connected to the top of the sliding groove. A second servo motor is fixedly connected to the upper surface of the L-shaped connecting column. The output shaft of the second servo motor is fixedly connected to one end of the second threaded rod. The second servo motor is electrically connected to the controller. The second servo motor drives the second threaded rod to rotate, and the second threaded rod drives the push column to slide downward in the sliding groove.

Pulling the sliding rod causes the snap-fit ​​post to move, disengaging it from the snap-fit ​​hole and compressing the return spring. Then, the L-shaped connecting post can be pulled out, facilitating the quick removal of the anti-fall structure for maintenance by the staff.

[0009] Each of the protective boxes has an L-shaped connecting rod fixedly connected to one side away from the other. The bottom of the two L-shaped connecting rods is fixedly connected to a fixed plate. The upper surface of the fixed plate has three second sliding grooves.

Then, the second servo motor drives the second threaded rod to rotate, which in turn drives the pushing column to slide downwards in the groove, moving the horizontally positioned tray down to an appropriate height. Then, the third servo motor drives the rotating frame to rotate, which in turn drives the horizontally positioned tray to rotate through the rotating block, moving the tray directly under the bearing. Finally, the tray moves upwards, so that the upper surface of the tray is in contact with the bottom of the bearing, preventing the bearing from falling due to insufficient friction during movement and causing bearing damage.

The first threaded rod 5 drives the moving block 6 to slide in the first moving groove. The moving block 6 drives the cylinder 8 to move, thereby moving the clamped bearing. To achieve the anti-fall structure, the anti-fall structure 12 includes an L-shaped connecting post 121 that snaps into the inside of the outer sleeve post 10. The upper surface of the L-shaped connecting post 121 has a snap-fit ​​hole, and the interior of the L-shaped connecting post 121 has a sliding groove. A second threaded rod 123 is rotatably connected to the top of the sliding groove. A second servo motor 124 is fixedly connected to the upper surface of the L-shaped connecting post 121.

Controller 3 controls the fifth servo motor 18, which drives the rotating rod 16 to rotate. The rotating rod 16 drives the worm gear 17 to rotate, which in turn drives the worm wheel 14. The worm wheel 14 drives the rotating shaft 13 to rotate, which in turn drives the rotating disk 15 to rotate. The rotating disk 15 drives the actuating column 23 to move via the arc groove. The actuating column 23 drives the sliding block 22 to slide on the limiting column 21. The sliding block 22 drives the clamping blocks 24 to move, so that the anti-slip pads on one side of the three clamping blocks 24 clamp onto the outer wall of the bearing. The clamping force is monitored by the second pressure sensor. When the clamping force reaches the threshold, controller 3 controls the fifth servo motor 18 to stop. Then, cylinder 8 drives the clamped bearing to move upwards. Simultaneously, controller 3 controls the fourth servo motor 129, which drives the rotating block 127 to rotate. 127 drives the tray 128 to rotate, making the tray 128 horizontally positioned. Then, the second servo motor 124 drives the second threaded rod 123 to rotate. The second threaded rod 123 drives the push column 122 to slide downward in the slide groove, moving the horizontally positioned tray 128 to a suitable height. Then, the third servo motor 125 drives the rotating frame 126 to rotate. The rotating frame 126 drives the horizontally positioned tray 128 to rotate through the rotating block 127, moving the tray 128 directly below the bearing. Then, the tray 128 moves upward, so that the upper surface of the tray 128 is in contact with the bottom of the bearing, preventing the bearing from falling due to insufficient friction during movement, which could damage the bearing. Pulling the sliding rod 112 causes the sliding rod 112 to move the locking column 113, causing the locking column 113 to disengage from the locking hole and compress the return spring 114. Then, the L-shaped connecting column 121 is pulled out, making it convenient for staff to quickly remove the anti-fall structure 12 for inspection and maintenance.
