Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4 The steel rim rounding mechanism shown in the figure comprises a workbench 1, a hydraulic cylinder 2, a lifting platform 3, a fastening member, and a restoring member. The hydraulic cylinder 2, the lifting platform 3, the fastening member, and the restoring member are all arranged on the workbench 1. It should be noted that, in this embodiment, the installation method of the hydraulic cylinder 2, the lifting platform 3, the fastening member, and the restoring member can refer to the technical content adopted in an adjustable wheel hub steel rim out-of-round shaping tool disclosed in the Chinese patent with publication number CN111482488A in the prior art, which will not be repeated here. A transmission cavity is opened in the workbench 1, and four sliding holes are opened on the top inner wall of the transmission cavity. Two transverse sliders 4 and two longitudinal sliders 5 are slidably installed in the four sliding holes, respectively. The two transverse sliders 4 and the two longitudinal sliders 5 are 5 are connected by a sliding assembly, and the tops of the two horizontal sliders 4 and the two longitudinal sliders 5 are each provided with a clamping assembly, and the clamping assembly includes a U-shaped block 11, and the U-shaped block 11 is fixedly installed on the top of the horizontal slider 4 or the longitudinal slider 5, and a partition 12 is fixedly installed on the side inner wall of the U-shaped block 11, and an equipment groove is opened on the bottom inner wall of the U-shaped block 11, and a rotating motor 13 is fixedly installed in the equipment groove, and the output shaft of the rotating motor 13 is rotatably connected to the bottom of the partition 12, and a rotating roller 14 is fixedly sleeved on the output shaft of the rotating motor 13, and a threaded rod 16 is rotatably installed on the top of the partition 12, and the top end of the threaded rod 16 extends to the outside of the U-shaped block 11 and is provided with a rotating unit, and a limit plate 18 is threadedly installed on the threaded rod 16.

[0023] By means of the above structure, when in use, the steel ring is first placed on the top of the workbench 1, and the two horizontal sliders 4 and the two longitudinal sliders 5 are driven by the sliding assembly to move synchronously in the axial direction, and then the four U-shaped blocks 11 and the four rotating rollers 14 are driven to move synchronously in the axial direction, so that the four rotating rollers 14 are in contact with the outer wall of the circumference of the steel ring, and then the four threaded rods 16 are rotated to drive the four limit plates 18 to move downward synchronously to limit the top of the steel ring, and then the four rotating motors 13 are used to drive the four rotating rollers 14 to rotate synchronously, and then the four rotating rollers 14 are used to drive the steel ring to realize the rotation function, so that the steel ring is rounded through the tightening parts and the restoring parts, and the repair effect is good and the practicability is strong.

[0024] like Figure 3As shown, the sliding assembly includes a first bidirectional screw rod 6 and a second bidirectional screw rod 7. The two ends of the first bidirectional screw rod 6 and the second bidirectional screw rod 7 are respectively rotatably installed on the circumferential inner wall of the transmission cavity. The first bidirectional screw rod 6 and the second bidirectional screw rod 7 are connected by a transmission unit. Two transverse sliders 4 and two longitudinal sliders 5 are respectively threadedly installed on the first bidirectional screw rod 6 and the second bidirectional screw rod 7. The advantage of such an arrangement is that, through the arrangement of the first bidirectional screw rod 6 and the second bidirectional screw rod 7, the rotation of the first bidirectional screw rod 6 and the second bidirectional screw rod 7 can realize the synchronous movement of the two transverse sliders 4 and the two longitudinal sliders 5 towards or away from the axis.

[0025] Specifically, when the first bidirectional screw 6 and the second bidirectional screw 7 rotate, the two transverse sliders 4 and the two longitudinal sliders 5 are driven to move synchronously toward or away from the axis through the action of the threads, thereby driving multiple rotating rollers 14 to move synchronously to achieve the clamping function of the steel ring.

[0026] like Figure 3 As shown, the transmission unit includes a worm 9 and a worm wheel 10. The worm 9 is arranged on the first bidirectional lead screw 6, and the worm wheel 10 is fixedly sleeved on the second bidirectional lead screw 7. The worm 9 and the worm wheel 10 are meshed and installed. A motor groove is opened on the side inner wall of the transmission cavity. A drive motor 8 is fixedly installed in the motor groove. The output shaft of the drive motor 8 is fixedly connected to the end of the first bidirectional lead screw 6. The advantage of such an arrangement is that through the arrangement of the worm 9 and the worm wheel 10, the first bidirectional lead screw 6 and the second bidirectional lead screw 7 can realize the synchronous rotation function.

[0027] Specifically, the drive motor 8 is started to drive the first bidirectional screw 6 to rotate, and then the worm 9 is driven to rotate through the first bidirectional screw 6, and the second bidirectional screw 7 is driven to achieve synchronous rotation function under the meshing action of the worm 9 and the worm wheel 10, so that the two horizontal sliders 4 and the two longitudinal sliders 5 can achieve synchronous movement function.

[0028] like Figure 4 As shown, a friction pad 15 is fixedly sleeved on the peripheral outer wall of the rotating roller 14. The advantage of such an arrangement is that the friction force of the rotating roller 14 can be enhanced by the arrangement of the friction pad 15, so that the rotating roller 14 drives the steel ring to rotate synchronously when rotating.

[0029] Specifically, when the rotating roller 14 rotates, it drives the friction pad 15 to rotate synchronously, so that the friction effect of the friction pad 15 drives the steel ring to realize the synchronous rotation function.

[0030] like Figure 4 As shown, the rotating unit includes a knob 17, the bottom end of the knob 17 is fixedly connected to the top end of the threaded rod 16. The advantage of such a setting is that, through the setting of the knob 17, the threaded rod 16 can be driven by the knob 17 to realize a convenient rotation function.

[0031] Specifically, when the threaded rod 16 needs to be rotated, the threaded rod 16 can be driven to realize the synchronous rotation function by rotating the knob 17, thereby driving the limit plate 18 to realize the lifting movement through the action of the thread.

[0032] like Figure 4 As shown, a limiting hole is provided on the inner wall of the side of the U-shaped block 11, and the limiting plate 18 is slidably installed in the limiting hole. The advantage of such a setting is that, through the setting of the limiting hole, a certain limiting function can be achieved for the limiting plate 18, preventing the threaded rod 16 from driving the limiting plate 18 to achieve synchronous rotation when rotating.

[0033] Specifically, by sliding the limit plate 18 in the limit hole, the limit plate 18 can achieve a limit function, so that when the threaded rod 16 rotates, the limit plate 18 can be driven by the thread to achieve a lifting function.

[0034] like Figure 3 As shown, a disc 19 is rotatably installed on the top of the workbench 1, and a protective pad is provided on the top of the disc 19. The advantage of such a setting is that through the setting of the disc 19, the steel ring can realize the convenient rotation function.

[0035] Specifically, when the steel ring is placed on the top of the disc 19, the setting of the disc 19 can realize the convenient movement function of the steel ring, and the setting of the protective pad can realize the protection function of the steel ring to prevent it from being damaged.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
