A rotating shaft 18 is rotatably clamped on the side of the support plate 1 near the gear 101. A half-face gear 19 that cooperates with the gear 101 is fixedly installed on the outside of the rotating shaft 18. The rotating shaft 17 and the rotating shaft 18 rotatably pass through the U-shaped frame 10. The number of teeth of the half-face gear 19 is one-tenth of the number of the frame 21.

[0019] The rotating shaft 17 is fixedly installed with a rotating disc 2 away from the side of the U-shaped frame 10. The rotating disc 2 is provided with a plurality of annularly and uniformly distributed frames 21. A square slot 20 is formed through one side of the rotating disc 2 and is used in cooperation with the frame 21. The thickness of the frame 21 is consistent with that of the rotating disc 2. Both sides of each frame 21 are fixedly installed with rotating rods 22. One of the rotating rods 22 is rotatably connected with the rotating disc 2. The other rotating rod 22 is fixedly installed with a rotating wheel 23 away from one side of the frame 21. A first clamping plate 24 is fixedly installed on one side of the inner wall of the frame 21. Two symmetrically distributed springs 26 are fixedly installed on the other side of the inner wall of the frame 21. A second clamping plate 25 is fixedly installed with the springs 26 away from one side of the rotating wheel 23 and is used in cooperation with the first clamping plate 24.

[0026] The bottom end edge of the horizontal plate 7 is fixedly installed with an L-shaped plate 72, the L-shaped plate 72 is fixedly connected with the support plate 1, the horizontal plate 7 is supported by the L-shaped plate 72, and the hydraulic rod 12 is more stable during work.

[0027] Working principle: in actual use, the rotating shaft 18 is controlled to rotate by the driving motor, meanwhile, the driving motor, the motor 14 and the hydraulic rod 12 are controlled to be turned on by an external controller, which is not shown in the drawing, when the bearing is ground, the bearing is placed between the first clamping plate 24 and the second clamping plate 25 in each frame 21, then the hydraulic rod 12 and the motor 14 are started, the motor 14 drives the driving shaft 15 and the grinding wheel 16 to rotate, the hydraulic rod 12 enables the grinding wheel 16 to move towards the bearing in front, so that the bearing is ground by the grinding wheel 16, when the grinding is completed, the hydraulic rod 12 drives the grinding wheel 16 to move back, the driving motor is started to drive the rotating shaft 18 and the half-face gear 19 to rotate, the half-face gear 19 is engaged with the gear 101 to drive the rotating shaft 17, the rotating disc 2, the frame 21 and the clamped bearing to rotate; when the next bearing rotates to the front of the grinding wheel 16, the gear 101 and the half-face gear 19 are not engaged, meanwhile, the grinding wheel 16 has approached the bearing to grind the bearing;

[0028] When one end surface of the bearing is ground and the square groove 20 corresponds to the empty groove 51, the rotating wheel 23 is rotated to drive the rotating rod 22, the frame 21 and the clamped bearing to rotate by 180 degrees, while the rotating rod 22 rotates, the connecting plate 31 is driven to rotate, the connecting plate 31 drives the clamping column 32 to slide in the semi-arc-shaped groove 33, when the clamping column 32 slides from one side of the inner wall of the semi-arc-shaped groove 33 to the other side of the inner wall, it indicates that the bearing has been turned over by 180 degrees, so that the other end surface of the bearing is ground, after the turning over, the rotating disc 2 rotates again;

[0029] When both end surfaces of the bearing are ground, the bearing reaches the position of the empty groove 51, the ground bearing is taken out, then when the first clamping plate 24 and the second clamping plate 25 do not have the bearing to reach the position of the empty groove 51, the unground bearing is placed, the rotating disc 2 does not rotate when the unground bearing is placed and the ground bearing is taken out;

[0030] When the bearing is placed between the first clamping plate 24 and the second clamping plate 25, the specific operation is as follows: first, the hand is put into the through slot 27, the second clamping plate 25 is pulled to the direction of the trapezoidal plate 3, the spring 26 is contracted, then the bearing is placed between the first clamping plate 24 and the second clamping plate 25, the hand is taken out of the through slot 27, the spring 26 rebounds, and then the bearing is clamped.
