A gear sleeve 703 is movably sleeved on the outer wall of the transmission rod 701. A limit groove 704 corresponding to the limit block 702 is formed on the inner wall of the gear sleeve 703. The limit groove 704 is slidably connected with the gear sleeve 703, which can stably guide the gear sleeve 703 and at the same time facilitate the gear sleeve 703 to drive the transmission rod 701 to rotate. A connecting block 705 is fixedly connected to the lower end of the transmission rod 701. A through groove 706 is formed on the side wall of the connecting block 705. An adjusting rod 707 is slidably arranged inside the through groove 706. A welding machine 708 is fixedly installed at one end of the adjusting rod 707, and the welding head of the welding machine 708 is inclined. A threaded sleeve block 709 is fixedly arranged at the other end of the adjusting rod 707. A threaded rod 710 is rotatably arranged on the side wall of the connecting block 705. The threaded rod 710 is threadedly sleeved with the threaded sleeve block 709, which is convenient for adjusting the horizontal position of the welding of the welding machine 708.

[0030] Furthermore, the adjusting assembly 7 further includes a motor 711 fixedly installed on the bottom surface of the upper end of the support frame 5, and the motor 711 is movably sleeved with the gear sleeve 703. The output end of the motor 711 penetrates through the support frame 5 and extends to be connected with a gear 712. The gear 712 is meshed with the upper end of the gear sleeve 703, which can drive the welding machine 708 to move around the connection point of the contact and the moving and static reeds for welding, improving the welding quality and efficiency.

[0031] Secondly, the bottom surface of the connecting block 705 is rotatably connected with an outer sleeve rod 8 through a bearing. An inner rod 9 is movably sleeved inside the outer sleeve rod 8. A pressing block 10 is fixedly connected to the lower end of the inner rod 9, and the pressing block 10 is located directly above the placing table 3.

After sleeving, they are placed on the upper surface of the support table 4, and the lower end of the contact is located in the groove on the upper surface of the support table 4 to ensure stable placement. Subsequently, the support table 4 is pushed directly below the pressing block 10 through the handle on one side of the placement table 3.

[0036] Further, start the cylinder 6. The output end of the cylinder 6 pushes the transmission rod 701 to move vertically downward. The transmission rod 701 drives the connecting block 705 to move vertically downward. The connecting block 705 drives the welding machine 708 to move vertically downward through the adjusting rod 707, so that the welding nozzle of the welding machine 708 is kept in a horizontal position with the contact. At the same time, the transmission rod 701 drives the outer sleeve rod 8 and the inner rod 9 to move vertically downward. The inner rod 9 drives the pressing block 10 to move vertically downward to contact the upper surface of the contact. The pressing block 10 is subjected to the resistance of the contact, causing the inner rod 9 to slide into the outer sleeve rod 8, and the pressing block 10 pushes the spring 11 to contract, thereby stably pressing the contact.

[0037] Furthermore, manually rotate the threaded rod 710 according to the size of the contact. The threaded rod 710 drives the threaded sleeve block 709 to move horizontally. The threaded sleeve block 709 drives the adjusting rod 707 to slide horizontally in the through groove 706. The adjusting rod 707 drives the welding machine 708 to move horizontally, so that the welding machine 708 closely adheres to the connection between the contact and the dynamic and static reeds. Then, start the motor 711. The motor 711 drives the gear 712 to rotate. The gear 712 drives the gear sleeve 703 to rotate. Through the engagement of the limit groove 704 on the inner wall of the gear sleeve 703 and the limit block 702 on the outer wall of the transmission rod 701, the transmission rod 701 rotates. The transmission rod 701 drives the connecting block 705 to rotate. The connecting block 705 drives the adjusting rod 707 to rotate. The adjusting rod 707 drives the welding machine 708 to perform circumferential welding at the connection between the contact and the dynamic and static reeds, which can complete the welding of the entire contact at one time without repeatedly adjusting the welding position. Therefore, the welding speed is fast, the production efficiency is high, and the circumferential welding can make the welding points evenly distributed on the entire contact, the welding is firm, and the welding quality is improved.

[0038] The above specific embodiments are merely several alternative embodiments of the present invention.
