Example 3

[0037] Please refer to Figures 1-8 On the basis of example 1 and example 2, the case 1 is further provided with a driving mechanism, the driving mechanism includes a hydraulic telescopic cylinder 8 fixedly connected in the inner cavity of the case 1, a moving box 9 fixedly connected with the output end of the hydraulic telescopic cylinder 8, a double-shaft motor 10 fixedly connected in the inner cavity of the moving box 9, a second gear 28 fixedly connected with the output shaft of the double-shaft motor 10, a third gear 29 meshing with the surface of the second gear 28, a worm 30 fixedly connected at the shaft center of the third gear 29, the worm 30 being rotatably connected with the inner wall of the moving box 9 through a bearing seat, a fourth gear 31 meshing with the surface of the second gear 28, and the fourth gear 31 being fixedly connected with the surface of the first threaded rod 3 at the shaft center.

[0039] The working principle of this invention is as follows: The operator places the annular part between the two first support wheels 6, and starts the dual-axis motor 10 through the control panel 2. The output shaft of the dual-axis motor 10 drives the fourth gear 31 to rotate through the second gear 28. The fourth gear 31 drives the first threaded rod 3 to rotate. The threaded sleeve 4 drives the support rod 5 and the first support wheel 6 to move horizontally until the first support wheel 6 is in contact with the lower surface of the annular part. During the horizontal movement of the first support wheel 6, the toothed plate 16 drives the second threaded rod 12 to rotate through the first gear 15. The second threaded rod 12 drives the second support wheel 7 to move downward through the threaded tube 13, so that it is in the same plane as the central axis of the annular part, thereby improving the clamping effect.

[0040] During the up-and-down movement of the second support wheel 7, the second support wheel 7 drives the adjusting wheel 20 to move up and down through the slider 18 and the fixed plate 19. At the same time, the drive wheel 14 drives the fixed plate 19 to move axially through the drive block 21. When the second support wheel 7 moves downward, the distance between it and the first support wheel 6 decreases. At this time, the adjusting wheel 20 moves outward. When the second support wheel 7 moves upward and downward, the distance between it and the first support wheel 6 increases. At this time, the adjusting wheel 20 moves inward, so that the synchronous belt 27 can be kept taut in real time, ensuring the transmission effect of the synchronous belt 27.

[0041] After clamping is completed, the hydraulic telescopic cylinder 8 is activated via the control panel 2. The hydraulic telescopic cylinder 8 drives the moving box 9 to move upward. At this time, the worm 30 and worm wheel 24 are engaged, while the second gear 28 and the fourth gear 31 are disengaged. The output shaft of the dual-axis motor 10 drives the worm 30 to rotate through the second gear 28 and the third gear 29. The worm 30 drives the worm wheel 24 to rotate. The worm wheel 24 drives the first synchronous pulley 25 through the fixed shaft. The first synchronous pulley 25 drives the second synchronous pulley 26 through the synchronous belt 27. Finally, the two first support wheels 6 and the two second support wheels 7 rotate synchronously, causing the annular part to rotate at a uniform speed. At this time, circumferential welding can be performed to ensure uniform weld quality.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
