At this time, the movable rod 15 can drive the positioning block 16 to move. Based on this, the positioning block 16 can be driven to move according to the size of the wheel hub, so that the positioning block 16 can position the wheel hub.

At this time, the positioning block 16 can be driven to move downward. When the movable rod 15 moves, it will drive the limit block 18 to move on the outer wall of the guide rod 19. When the bottom of the positioning block 16 is in contact with the top of the wheel hub, the rotating motor 21 is stopped. At this time, the positioning block 16 and the carrier frame 12 complete the positioning of the wheel hub;

[0039] The drilling head 11 is fine-tuned according to the position of the hole required to be drilled in the wheel hub, and the drive motor 6 is started to drive the first screw rod 5 to rotate in the inner cavity of the adjustment groove 3, so that the adjustment block 4 can be threadedly connected to the first screw rod 5, so that the adjustment block 4 can move in the inner cavity of the adjustment groove 3. After the adjustment block 4 moves, the drive assembly 9 and the drilling head 11 can be driven to move by the servo motor 8.
