the adjusting device comprises an adjusting device body, a motor and a control device, wherein the adjusting device body is used for fixing an encoder selecting rotating shaft and the motor, and the coded disc is connected with the motor through the encoder rotating shaft;

2. The encoder adjustment device of claim 1, wherein the adjustment module comprises:

the adjusting block is used for adjusting the position of the coded disc relative to the encoder rotating shaft so that the coded disc is in the preset position.

3. The encoder adjuster of claim 1, wherein the adjustment module further comprises an optical probe connected to the adjuster body, the optical probe being configured to detect an actual position of the code wheel.

4. The encoder adjuster of any one of claims 1-3, wherein the adjuster body includes:

one side of the bearing seat, which is far away from the motor fixing plate, is used for fixing the encoder rotating shaft, and the space between the motor fixing plate and the bearing seat is used for accommodating the encoder rotating shaft.

5. The encoder adjusting device according to claim 4, wherein the bearing seat is provided with a first through hole penetrating through the bearing seat, the motor fixing plate is provided with a second through hole penetrating through the motor fixing plate, and the first through hole and the second through hole are arranged oppositely;

the first through hole is used for the encoder rotating shaft to penetrate through to be connected with the coded disc, and the second through hole is used for the motor shaft of the motor to penetrate through the second through hole to be connected with the encoder rotating shaft.

6. The encoder adjusting device of claim 4, wherein a side of the motor fixing plate facing the bearing seat is provided with a groove for arranging an optical detector;

the bearing seat is provided with a detection through hole penetrating through the bearing seat, and the optical detector detects the actual position of the code disc through the detection through hole.

7. The encoder adjustment device of claim 5, wherein the adjustment device body further comprises:

the hollow support is fixed on one side, far away from the bearing seat, of the motor fixing plate, a third through hole is formed in the hollow support, the inner space of the hollow support is used for containing the motor, and the third through hole is used for enabling a motor shaft of the motor to penetrate through to enter the second through hole.

8. The encoder adjustment device of claim 7, wherein the hollow support comprises:

and one surface of the top plate, which is far away from the bottom plate, is used for bearing the adjusting module and the bearing seat.

9. The encoder adjuster of claim 8, wherein the side plate is provided with an opening for the motor to be disposed inside the hollow bracket through the opening.

10. The encoder adjustment device of any one of claims 7-9, wherein the geometric centers of the first through hole, the second through hole, and the third through hole are located on a same line.
