The feeding upper cover 13 is provided with two feeding ports 11. The aperture of the feeding port 11 is larger than the outer diameter of the bearing 7. The gap between the feeding upper cover 13 and the supporting platform is larger than the width dimension of a single bearing 7 and smaller than the width dimension of two bearings 7, so as to ensure that only one bearing enters the limiting table each time. The distance between the limiting plates on the left and right sides is larger than the width dimension of a single bearing 7, so as to ensure that the bearing can maintain a stable feeding direction in the limiting table. The front end and side of the supporting platform are provided with limiting blocks, including a transverse limiting block and a longitudinal limiting block, for positioning and limiting the bearing 7 pushed out by feeding, so as to facilitate the clamping and loading assembly to grab and load.

[0024] Refer to Figure 1 , the feeding assembly includes a feeding cylinder and a feeding push block 12. The feeding push block 12 is driven by the push rod of the feeding cylinder to horizontally expand and slide. The end face of the feeding push block 12 in the advancing direction is set as a profiling groove of the outer ring of the bearing 7. Refer to Figure 4 , so as to facilitate the stable feeding of the bearing 7.

[0025] Refer to Figure 2 and Figure 4 , the borrowing assembly is arranged on the left side of the limiting block and is used to push the bearing 7 fed into the limiting block at the feeding port 11 that is not the rightmost one to the right until it reaches the positioning place where the only bearing 7 is to be loaded, including a borrowing cylinder 4 and a borrowing push block 16. The end face of the borrowing push block 16 in the advancing direction is set as a profiling structure of the outer ring of the bearing 7.

[0026] Refer to Figure 3 and Figure 4, the clamping and loading component is arranged above the positioning position of the only bearing 7 to be loaded, and includes a loading cylinder 15, a lifting cylinder 6 and a pneumatic gripper 5. The lifting cylinder 6 is driven by the loading cylinder 15 to achieve a horizontal linear sliding action, and the pneumatic gripper 5 is driven by the lifting cylinder 6 to achieve a lifting action. A gripper 10 for clamping the inner ring of the bearing 7 is arranged below the pneumatic gripper 5.

[0027] Refer to Figure 2 , a limiting rod 9 is arranged on one side of the cylinder block of the lifting cylinder 6, and the lower end of the limiting rod 9 faces the supporting platform, so as to ensure that the displacement amount during the descending process of the pneumatic gripper 5 is controllable.

[0028] Refer to Figure 4 , a chamfer 14 is arranged at the feeding port 11 to ensure that the bearing 7 falling from the guide rod structure 8 accurately falls into the feeding port 11.

[0029] A further implementation scheme is that a soft rubber is arranged on the clamping surface of the gripper 10.

[0030] The working principle is:

[0031] The guide rod structure is used to stack and sleeve the bearings layer by layer, and the limiting platform is used to stably feed and push the single bearing at the bottom layer to the positioning position to be loaded. After the bearing is clamped by the pneumatic gripper, under the coordinated cooperation of each cylinder, it is loaded onto the assembly production line. Multiple groups of parallel guide rod structures are provided, which can carry out the orderly and staggered feeding and loading of a batch of bearings.
