The wedge-shaped block 701 is inserted into the wedge-shaped groove 501 between the clamping block 5 and the support plate 4. Since the wedge-shaped block 701 and the clamping block 5 are in contact with the inclined surface, the clamping block 5 will be pushed to move horizontally towards the hub 14 during the downward movement of the wedge-shaped block 701. Then, the two clamping blocks 5 can clamp and fix the hub 14. Then, the hub fixing frame 2 is pushed along the slide rail 11 to the bottom of the press-fitting machine 8 by the operating handrail 13. Then, various parts are press-fitted onto the hub 14 by the press-fitting machine 8.

[0044] After the pressing is completed, the hub fixing frame 2 is pushed out to the outside of the pressing machine 8 by operating the handrail 13, then the piston rod of the pushing device 703 is controlled to be elongated, the wedge block 701 is driven to move upward, and is gradually separated from the wedge-shaped groove 501. Since the clamping block 5 moves towards the hub 14, the guide rod 601 and the baffle 602 are synchronously moved, the baffle 602 is compressed during the movement, when the wedge block 701 moves upward, the clamping block 5 is driven to move away from the hub 14 under the elastic force of the spring 603, and returns to the initial position. At this time, the hub 14 can be conveniently taken down or flipped.
