[0031] Working principle:

[0032] During use, the shaft 19 is conveyed into the feeding slide rail 6 by the vibrating disk feeder 4 of the machine. And the shaft 19 is conveyed through the feeding slide rail 6 to be close to the lower part of the riveting head 9. At this time, the two elastic balls 14 will block the shaft 19. By pushing the shaft 19, the two elastic balls 14 will undergo elastic deformation, and the shaft 19 is pushed to the left of the two elastic balls 14 and then contacts the arc-shaped plate 13. And the arc-shaped plate 13 moves to the left. The leftward movement of the arc-shaped plate 13 drives the connecting plate 11 to move to the left, and then drives the spring 12 to contract. At this time, the two elastic balls 14 return to their original state, and the shaft 19 is limited by the clamping of the two elastic balls 14 and the arc-shaped plate 13. By providing anti-slip grooves inside the notch of the arc-shaped plate 13, the clamping stability of the shaft 19 is improved.

[0033] The rotor 20 is sleeved outside the shaft 19; then the limit ring 21 is sleeved outside the rotor 20; the two knobs 18 are rotated, so that the two threaded rods 16 rotate, and the two threaded rods 16 drive the two clamping plates 17 to move closer, and then the position of the limit ring 21 is fixed; by starting the hydraulic cylinder 7, the output end of the hydraulic cylinder 7 moves downward to drive the slider 8 to move downward, and then the riveting head 9 moves downward to perform riveting operation on the shaft 19.

[0034] After the riveting operation is completed, take out the shaft 19 and the rotor 20. Insert the next shaft 19 to be riveted through the notch of the limiting ring 21 and place it between the two elastic balls 14 and the arc-shaped plate 13. Then, install the rotor 20 correspondingly between the outside of the shaft 19 and the inner wall of the limiting ring 21. Subsequently, the riveting operation can be carried out. After the riveting is completed, repeat the above actions to continuously perform the riveting operation.
