This device features an adjustment structure for rapid riveting removal and precise positioning of the welding position, enabling fast and lightweight welding operations. It also includes a disassembly structure for convenient electrode removal and replacement, ensuring work efficiency and improving work safety and stability.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A riveting device for resistance riveting includes a top plate, four support columns fixedly connected to the bottom of the top plate, a base fixedly connected to the bottom of the support columns, and an adjustment structure fixedly connected to one side of both the top plate and the base, wherein a disassembly structure is fixedly connected to the bottom of one of the adjustment structures.

[0007] The adjustment structure includes a first motor located inside one side of the top plate and the base. The output end of the first motor is fixedly connected to a first threaded rod. The external thread of the first threaded rod is fitted with a first sliding plate. The inside of the first sliding plate is fixedly connected to a second threaded rod. One end of the second threaded rod is fixedly connected to a second motor. Both ends of the second threaded rod are connected through limit rods.

[0009] Furthermore, the disassembly structure includes a handle located at the bottom of the adjustment structure. One end of the handle is fixedly connected to a locking rod, and a second spring is sleeved on the outside of the locking rod. The locking rod is engaged with a fixing plate through a locking groove.

[0010] By using the above technical solution, a disassembly structure is set up. Pulling the handle disengages the lever from the slot, unlocking the fixing plate, and then the lower cylinder and clamping column can be removed for maintenance of the first electrode.

[0018] By using the above technical solution, the slide cylinder and the clamping column are misaligned by the third spring and the second sliding plate, which can buffer and depress the slide cylinder, thereby making the first electrode stick tightly to the rivet and the dissimilar metal plate.

[0019] Furthermore, a first spring is fixedly connected inside the clamping column, and a ball bearing is fixedly connected to one end of the first spring;

[0020] The above technical solution uses a first spring and a ball bearing to clamp the rivet, then adjusts the structure to send the rivet to the welding position, and squeezes the ball bearing to make it rebound and weld the rivet to the welding point.

A telescopic rod 6 is fixedly connected inside the first sliding groove 8. A slider 7 is fixedly connected to one end of the telescopic rod 6. A pressure plate 4 is fixedly connected to one end of the slider 7. A dissimilar metal plate 12 is set at the bottom of the pressure plate 4. The slider 7 is controlled to slide in the first sliding groove 8 by the telescopic rod 6, thereby controlling the pressure plate 4 to press down and thus reinforcing the dissimilar metal plate 12. A fixing block 508 is fixedly connected to the bottom of the slide rod 507. A hydraulic rod 17 is installed inside the fixing block 508. A fixing column 18 is fixedly connected to the bottom of the hydraulic rod 17. A slide cylinder 10 is installed at the bottom of the fixing column 18. A clamping column 11 is engaged with the bottom of the slide cylinder 10. A second electrode 15 is fixedly connected to the top of another slide rod 507. A first electrode 19 is fixedly connected to the bottom of the fixing column 18. The first electrode 19 is connected to the clamping column 11. The first electrode 19 and the second electrode 15 are fixedly connected to one end of the slide rod 507 respectively. By controlling the movement of the slide rod 507, the first electrode 19 and the second electrode 15 are also controlled to move, achieving precise positioning for resistance riveting. A conveyor seat 16 is provided on one side of the base 2. The 16 is equipped with a conveyor belt 14, and a rivet 13 is provided on the top of the conveyor belt 14. The rivet 13 is transported by the conveyor belt 14, so that after the clamping column 11 takes the rivet 13 at the corresponding position, the subsequent rivet 13 moves to the blank position, so that the rivet 13 can be quickly replenished. The slide cylinder 10 is equipped with a second slide groove 20, and a second slide plate 23 slides inside the second slide groove 20. A third spring 24 is fixedly connected to the bottom of the second slide plate 23. The end of the third spring 24 away from the second slide plate 23 is fixedly connected to the slide cylinder 10.

By squeezing, the ball bearing 21 rebounds, welding the rivet 13 to the welding point.

[0036] Working principle: When using this riveting device for resistance riveting, the dissimilar metal plate 12 is placed on the base 2. The telescopic rod 6 controls the slider 7 to slide in the first slide groove 8, thereby controlling the pressure plate 4 to press down, thus reinforcing the dissimilar metal plate 12. Then, the first motor 501 and the second motor 504 are started to control the clamping column 11 to clamp the rivet 13. Then, the first electrode 19 and the second electrode 15 are controlled to move and position. After reaching the specified position, the first electrode 19 and the second electrode 15 are used to heat the rivet 13 and the dissimilar metal plate 12. After reaching the welding temperature, the hydraulic rod 17 is started to squeeze the first electrode 19, so that the first electrode 19 and the rivet 13 are separated from the clamping column 11, thereby welding the rivet 13 to the dissimilar metal plate 12, achieving precise spot welding. Furthermore, by pulling the handle 901, the clamping rod 903 can be disengaged from the slot 904, and the fixing plate 905 can be unlocked, so that the slide cylinder 10 and the clamping column 11 can be removed, and the first electrode 19 can be maintained.
