[0036] The clamping mechanism includes a mounting frame 29, a placement seat 30, a transverse cylinder 31, a push plate 32, an abutment plate 33, a longitudinal cylinder 34, and a pressure block 35. The mounting frame 29 is fixed on the mounting platform 1, the placement seat 30 is fixed on the mounting frame 29, the transverse cylinder 31 is fixed on the placement seat 30, the push plate 32 is fixed on the extension end of the transverse cylinder 31, the abutment plate 33 is fixed on the outside of the placement seat 30, multiple sets of longitudinal cylinders 34 are fixed on the mounting frame 29, and the pressure block 35 is installed on the extension ends of multiple sets of longitudinal cylinders 34.

[0037] In this embodiment, during use, the connecting rod to be assembled is placed on the placement seat 30. The transverse cylinder 31 pushes the push plate 32 to clamp the connecting rod between the abutment plate 33 and the push plate 32. Multiple sets of longitudinal cylinders 34 push the pressure block 35 to clamp the two ends of the connecting rod. The motor 3 drives the riveting head 4 to rotate. The extension end of the hydraulic cylinder 2 retracts, driving the motor 3 to move, thereby driving the riveting head 4 to perform riveting operations on the connecting rod. When the riveting head 4 needs to be replaced, the rotating sleeve 24 rotates, causing the unlocking sleeve 25 to rotate. The unlocking sleeve 25 drives multiple sets of unlocking holes 26 to move below multiple sets of top rods 23, so that... Multiple sets of top rods 23 release their contact with the unlocking sleeve 25, then push the limiting sleeve 22 to release its contact with multiple sets of limiting blocks 20 and squeeze multiple sets of compression springs 28. Multiple sets of reset springs 27 pull the limiting blocks 20 outward to make them disengage from the limiting groove 21, releasing the restriction on the sliding sleeve 13. The tension spring 15 pulls the sliding sleeve 13 to slide along the outer wall of the fixed sleeve 5, thereby causing multiple sets of sliders 8 to slide along the inclined groove 14. At the same time, the connecting rod is driven to stretch the contraction spring. The slider 8 drives the locking block 7 to disengage from the locking groove 12 through the sliding rod 6, releasing the insertion of the insertion rod 11 and the multiple sets of locking blocks 7, completing the disassembly of the counterspinning riveting head 4.

[0038] More specifically, when installing the riveting head 4, the insertion rod 11 is positioned and inserted into the fixed sleeve 5 through multiple sets of positioning grooves 18 and positioning strips 17. The sliding sleeve 13 is pushed to stretch the tension spring 15. Multiple sets of contraction springs are reset and pull the slider 8 to slide along the inclined groove 14. The sliding rod 6 pushes the locking block 7 to engage in the slot 12. When multiple sets of limiting blocks 20 move to the outside of the limiting groove 21, multiple sets of compression springs 28 are reset and push the limiting sleeve 22 to abut against the outside of the multiple sets of limiting blocks 20. The multiple sets of limiting blocks 20 are then engaged in the limiting groove 21. At the same time, multiple sets of reset springs 27 are squeezed to limit the sliding sleeve 13. When multiple sets of top rods 23 are disengaged from the unlocking hole 26, the rotating sleeve 24 is rotated to drive the unlocking sleeve 25 to abut against the bottom of the multiple sets of top rods 23 and limit the limiting sleeve 22.

[0039] In summary, during use or operation of the overall equipment: When in use, the connecting rod to be assembled is placed on the placement seat 30. The transverse cylinder 31 pushes the push plate 32 to clamp the connecting rod between the abutment plate 33 and the push plate 32. Multiple sets of longitudinal cylinders 34 push the pressure blocks 35 to clamp the two ends of the connecting rod. The motor 3 drives the riveting head 4 to rotate. The retraction end of the hydraulic cylinder 2 retracts, driving the motor 3 to move, thereby driving the riveting head 4 to perform riveting operations on the connecting rod. When the riveting head 4 needs to be replaced, rotating the rotating sleeve 24 drives the unlocking sleeve 25 to rotate. The unlocking sleeve 25 drives multiple sets of unlocking holes 26 to multiple sets of top rods 23. Below, the multiple sets of top rods 23 are released from contact with the unlocking sleeve 25, and then the limiting sleeve 22 is pushed to release the contact with the multiple sets of limiting blocks 20 and squeeze the multiple sets of compression springs 28. The multiple sets of reset springs 27 pull the limiting blocks 20 outward to make them disengage from the limiting groove 21, releasing the restriction on the sliding sleeve 13. The tension spring 15 pulls the sliding sleeve 13 to slide along the outer wall of the fixed sleeve 5, thereby causing the multiple sets of sliders 8 to slide along the inclined groove 14. At the same time, the connecting rod is driven to stretch the contraction spring. The slider 8 drives the locking block 7 to disengage from the locking groove 12 through the sliding rod 6, releasing the insertion of the insertion rod 11 and the multiple sets of locking blocks 7, completing the disassembly of the counterspinning riveting head 4.

[0040] When the riveting head 4 is installed, the insertion rod 11 is inserted into the fixed sleeve 5 through multiple positioning grooves 18 and positioning strips 17. The sliding sleeve 13 is pushed to stretch the tension spring 15. Multiple sets of contraction springs are reset and pull the slider 8 to slide along the inclined groove 14. The sliding rod 6 pushes the locking block 7 to engage in the slot 12. When multiple sets of limiting blocks 20 move to the outside of the limiting groove 21, multiple sets of compression springs 28 are reset and push the limiting sleeve 22 to abut against the outside of the multiple sets of limiting blocks 20. The multiple sets of limiting blocks 20 are also pushed to engage in the limiting groove 21. At the same time, multiple sets of reset springs 27 are squeezed to limit the sliding sleeve 13. When multiple sets of top rods 23 are disengaged from the unlocking hole 26, the rotating sleeve 24 is rotated to drive the unlocking sleeve 25 to abut against the bottom of the multiple sets of top rods 23 and limit the limiting sleeve 22.
