A lifting electric cylinder 9 penetrates through the middle position of the top end of the frame body 5. A connecting plate 7 is arranged at the bottom end of the lifting electric cylinder 9. A driving motor 10 is arranged at the middle position of the bottom end of the connecting plate 7. An internal hexagonal sleeve 3 is arranged at the output end of the driving motor 10. The lifting electric cylinder 9 is used to push the driving motor 10 and the internal hexagonal sleeve 3 to descend, and the internal hexagonal sleeve 3 is sleeved on the universal wheel assembly nut. Starting the driving motor 10 to drive the internal hexagonal sleeve 3 to rotate can tighten the bolts to assemble the universal wheel;

[0022] As a further implementation manner of this embodiment, as Figures 1-4 shown, cylinders 16 are arranged on both sides of the bottom end of the connecting plate 7, and the cylinders 16 are symmetrically arranged at the bottom of the connecting plate 7. A telescopic rod 6 is inserted at the bottom end inside the cylinder 16. The telescopic rod 6 can slide up and down relatively at the bottom end inside the cylinder 16. A stable pressing plate 12 is arranged at the bottom end of the telescopic rod 6. A second limiting block 15 is arranged inside the cylinder 16 at the top end of the telescopic rod 6. The telescopic rod 6 is limited inside the cylinder 16 by the second limiting block 15. When the lifting electric cylinder 9 is used to push the connecting plate 7 to drive the assembly fastening mechanism to descend to assemble the universal wheel, the cylinder 16 descends accordingly, and at the same time, the stable pressing plate 12 is pushed to descend and fit on the universal wheel. A compression spring 11 is arranged outside the cylinder 16 between the stable pressing plate 12 and the connecting plate 7. The top end of the compression spring 11 is fixedly connected to the bottom end of the connecting plate 7, and the bottom end of the compression spring 11 is fixedly connected to the top end of the stable pressing plate 12. The elastic force of the compression spring 11 is used to push the stable pressing plate 12 to press tightly on the universal wheel, thereby further ensuring the stability of the universal wheel during the assembly process and avoiding the influence of the universal wheel from moving during the assembly operation on the assembly effect;

[0023] When the lifting electric cylinder 9 is used to push the connecting plate 7 to drive the assembly fastening mechanism to descend to assemble the universal wheel, the cylinder 16 descends accordingly, and at the same time, the stable pressing plate 12 is pushed to descend and fit on the universal wheel. At the same time, as the lifting electric cylinder 9 continuously descends, the compression spring 11 is compressed, so that the stable pressing plate 12 tightly fits on the universal wheel, and the telescopic rod 6 rises relatively inside the cylinder 16 to stabilize the compression spring 11, and the telescopic rod 6 is limited inside the cylinder 16 by the second limiting block 15;

[0024] As a further implementation manner of this embodiment, as Figure 1 、 Figure 2 and Figure 4As shown in the figure, a stabilizing component is provided between the two sides of the top of the connecting plate 7 and the top end inside the housing 5. The stabilizing component includes stabilizing guide rods 8. The stabilizing guide rods 8 are arranged on the two sides of the top end of the connecting plate 7 and are symmetrically arranged on the top of the connecting plate 7. At the middle positions on both sides of the top end inside the housing 5, stabilizing sleeves 13 are penetrated. The top ends of the stabilizing guide rods 8 penetrate into the inside of the stabilizing sleeves 13. The stabilizing guide rods 8 can slide up and down relatively inside the stabilizing sleeves 13. When the connecting plate 7 moves up and down, the stabilizing guide rods 8 slide up and down relatively inside the stabilizing sleeves 13 accordingly. A first limiting block 14 is arranged at the top end of the stabilizing guide rod 8. The stabilizing guide rod 8 is limited inside the stabilizing sleeve 13 by using the first limiting block 14, so as to ensure that the lifting electric cylinder 9 stably and accurately pushes the hexagon socket head cap wrench 3 to be sleeved on the universal wheel mounting nut for fastening operation and ensure the assembly accuracy.

[0025] When the connecting plate 7 is driven to move up and down, the stabilizing guide rods 8 slide up and down relatively inside the stabilizing sleeves 13 accordingly, and the stabilizing guide rods 8 are limited inside the stabilizing sleeves 13 by the first limiting block 14, so as to ensure that the lifting electric cylinder 9 stably and accurately pushes the hexagon socket head cap wrench 3 to be sleeved on the universal wheel mounting nut for fastening operation.

[0026] Specific working principle:

[0027] When using the assembly device, first pass the screw rod through the bearing arranged inside the wheel, then use the positioning seat 2 to position and place the universal wheel and the assembly bolt, and sleeve the nut sleeve on the screw rod. Then, the assembly worker controls and starts the lifting electric cylinder 9 through the controller 4 to push the drive motor 10 and the hexagon socket head cap wrench 3 to descend, and sleeve the hexagon socket head cap wrench 3 on the universal wheel assembly nut. At the same time, the stabilizing guide rods 8 slide down relatively inside the stabilizing sleeves 13, and the stabilizing guide rods 8 are limited inside the stabilizing sleeves 13 by the first limiting block 14, so as to ensure that the lifting electric cylinder 9 stably and accurately pushes the hexagon socket head cap wrench 3 to be sleeved on the universal wheel mounting nut. And when the lifting electric cylinder 9 pushes the connecting plate 7 to drive the assembly fastening mechanism to descend to assemble the universal wheel, the cylinder body 16 descends accordingly, and at the same time, it pushes the stabilizing pressing plate 12 to descend and fit on the universal wheel. At the same time, as the lifting electric cylinder 9 continuously descends, the compression spring 11 is compressed so that the stabilizing pressing plate 12 tightly fits on the universal wheel. Then, start the drive motor 10 to drive the hexagon socket head cap wrench 3 to rotate to tighten the bolt and assemble the universal wheel.
