A telescopic rod 13 is slidably provided inside the handle 11, and one end of the telescopic rod 13 is located inside the rotating cover 7 and points to the ratchet 10. A telescopic component 14 is provided between the inner wall of the handle 11 and the telescopic rod 13, which drives the telescopic rod 13 to extend and retract by rotating the handle 11. The rotating cover 7 is driven to rotate by the handle 11, and the driving component drives multiple blocks 9 to move toward the center of the rotating cover 7 at the same time to achieve the positioning of the end cover. At the same time, by rotating the handle 11, the telescopic component 14 drives the telescopic rod 13 to move toward the ratchet 10 to achieve the locking of the block 9. Compared with the existing device, the problem of cumbersome steps caused by the need to manually rotate the screw to drive the positioning claw for positioning in the prior art and then realize the locking of the positioning claw through an additional locking step is avoided, thereby improving the grinding efficiency. The telescopic component 14 is a prior art, including a sleeve with a built-in thread, and one end of the telescopic rod 13 is threadedly sleeved in the sleeve.

[0021] Reference Figure 1 The moving component includes a lead screw 15 rotatably connected to the first slide groove 4, a first motor 16 for driving the lead screw 15 to rotate is fixedly installed on one side of the base plate 1, the bottom end of the sliding plate 5 extends into the first slide groove 4 and is threadedly sleeved on the lead screw 15, and the lead screw 15 is driven to rotate by the first motor 16, thereby realizing the movement of the moving plate.

[0022] Reference Figure 4 An arc-shaped rubber pad 17 is fixedly connected to the side of the stop block 9 facing the center of the rotating disk, and the bottom surface of the rubber pad 17 is flush with the top surface of the rotating cover 7. The arc-shaped rubber pad 17 can increase the contact area with the end surface, improve the friction force, increase the positioning stability, and provide a buffer to avoid the stop block 9 from crushing the end cover as much as possible.

[0026] Working principle:

[0027] When using the output shaft end cover grinding device, the end cover needs to be placed at the center of the rotating cover 7. At this time, hold the handle 11 and drive the rotating cover 7 to rotate, so that the toothed plate 19 rotates with the stop block 9, and drives the stop block 9 to move toward the end cover with the relative rotation of the flat thread 20 until the rubber pad 17 abuts the end cover. At this time, rotate the handle 11 and drive the sleeve to rotate, thereby driving the telescopic rod 13 to move toward the ratchet 10 until the telescopic rod 13 abuts the ratchet 10. At this time, the motor can be turned on and the lead screw 15 can be driven to rotate, and the sliding disk 5 moves accordingly until it is located directly below the grinding assembly 3, and the grinding of the end cover can be started. After the grinding is completed, the motor is reversed until the sliding disk 5 moves to the initial position. At this time, the handle 11 is rotated in the opposite direction and the rotating cover 7 is driven to rotate in the opposite direction to remove the end cover. The above is the entire use process of the output shaft end cover grinding device.
