Traditional welding equipment has many disadvantages in the manufacturing process of sports equipment. On the one hand, most of them are single-point welding modes. When multiple parts of sports equipment need to be welded, they can only be carried out one by one, which takes a lot of time and seriously affects production efficiency. For example, a complex fitness equipment frame has dozens of welding points. Using single-point welding equipment, the welding cycle is lengthy.

Moreover, the existing equipment has poor versatility and is difficult to adapt to the diverse shapes and structures of sports equipment. Frequent replacement of accessories increases costs and takes time. In addition, the high degree of dependence on manual operation and insufficient automation level not only increase labor intensity, but also easily cause unstable welding quality due to human factors, especially in the process of argon welding, the tungsten electrode is damaged after long-term use.

[0026] Specifically, through the threaded connection, the external threaded joint 728 and the adjustment component 73 connected thereto can be easily installed and disassembled. When the adjustment component 73 needs to be replaced, it can be achieved by simply rotating the external threaded joint 728. The operation is simple and quick, which saves equipment debugging and preparation time and improves production efficiency. The above-mentioned replacement method does not require human intervention and is fully automated. It only requires the adjustment component 73 to be placed in a preset position in advance, which reduces the work difficulty and labor intensity of the operator. Especially in the process of mass production of sports equipment, the equipment can be quickly adjusted and optimized to ensure the smooth progress of the production process.

[0027] In this embodiment, if Figure 11-13As shown, an adjustment component 73 is provided at one end of the external threaded joint 728, and the adjustment component 73 includes a sleeve cap 731 sleeved with one end of the external threaded joint 728, a connecting hole is provided at one end of the sleeve cap 731, a bearing 732 is rotatably connected to the inner wall of the connecting hole, and a docking cap 733 is fixedly connected to the inner ring of the bearing 732, an annular groove 734 is provided inside the sleeve cap 731, and a card slot is provided on the inner wall array of the sleeve cap 731, one end of the card slot extends to the outside of the sleeve cap 731, the inner wall of the card slot is fixedly connected to the inner wall of the annular groove 734, and a limit hook 735 adapted to the surface of the hook 729 is provided inside the card slot.

[0028] Specifically, the bearing 732 is rotatably connected in the connecting hole at one end of the sleeve cap 731, and the inner ring of the bearing 732 is fixedly connected to the docking cap 733, thereby ensuring the relative rotation of the internal structure. At the same time, through the threaded connection between the sleeve cap 731 and the external threaded joint 728, the adjustment component 73 and the external threaded joint 728 can be firmly connected to prevent loosening or falling off due to vibration or operating actions during the welding process, thereby ensuring the stability and reliability of the entire welding mechanism 7; the card slot and the limiting hook 735 inside it are adapted to the hook 729, and the sleeve cap 731 can be firmly fixed on the hook 729 of the external threaded joint 728 through the limiting hook 735.

Compared with electrodes in fixed positions, its flexibility can make the tungsten electrode 2 739 more convenient to adjust to the optimal welding position and angle, thereby improving the accuracy and adaptability of welding. During the welding process of sports equipment, different welding positions and shapes require different gas protection angles. The flexible rotation of the rotating nozzle 737 can adjust the gas flow direction according to actual conditions, ensuring that the welding area is fully covered by the protective gas, preventing the welding area from being oxidized, and improving the welding quality.

In order to ensure that the tungsten electrode 720 is completely close to the inside of the docking cap 733, the rectangular groove is set so that when the tungsten electrode 720 squeezes the docking cap 733, the sheet-like body of the docking cap 733 is biased outward, which facilitates the insertion of the tungsten electrode 720 into the docking cap 733, while ensuring the relative position accuracy between the two, ensuring the electrical connection and energy transfer efficiency during welding.

[0031] In this embodiment, the universal joint 738 is made of metal tungsten.

[0032] Specifically, similar to the butt cap 733, benefiting from the high melting point, high hardness and high temperature stability of tungsten, its mechanical properties and structural stability can be guaranteed in the high temperature environment of welding, providing reliable support and connection for the flexible movement of tungsten electrode 2 739. Its stability at high temperature is crucial to ensuring that tungsten electrode 2 739 can accurately reach the required welding position and angle, which helps to improve the accuracy and reliability of welding.

[0033] In this embodiment, the material of the bearing 1 732 is tungsten-rhenium alloy, and the contact point between the inner ring of the bearing 1 732 and the universal joint 738 is coated with an insulating coating.

[0034] Specifically, current will be passed through tungsten electrode 1 720 and tungsten electrode 2 739. Applying an insulating coating at the contact point can prevent the current from being conducted through bearing 1 732, avoiding unnecessary electrical interference or leakage, ensuring the electrical safety of the equipment and the stability of the welding operation. At the same time, it can also prevent damage to bearing 1 732 due to electrical problems, extend the service life of bearing 1 732, and improve the overall reliability of the equipment.

Step 2: At the same time, the joint of the plate chain conveyor belt 1 4 and the joint of the equipment 1 8 are at the same height, and the piston rod of the cylinder 10 drives the electric clamp 11 to approach the equipment 2 9, and the clamping part of the electric clamp 11 forms a clamping effect with the equipment 1 8. After the clamping is completed, the piston rod of the cylinder 10 continues to extend until the two joints of the equipment 1 8 and the equipment 2 9 contact each other; Step 3, install the adjustment component 73 on one side of each docking component 72 respectively, after one end of the external threaded connector 728 enters the sleeve cap 731, the hook 729 is inserted into the slot, and the limiting hook 735 in the slot is squeezed, and the part of the limiting hook 735 located in the annular groove 734 leaves the annular groove 734, and the hook 729 and the limiting hook 735 complete the limiting, and the two are engaged with each other under the action of the spring 736, and at the same time, one end of the tungsten electrode 720 is inserted into the docking cap 733, and the motor 721 drives the gear rod 724 to rotate through the output shaft, and then drives the threaded tube 727 to rotate through the gear 725, and the screw The corrugated tube 727 and the external threaded connector 728 are threadedly connected. When the threaded tube 727 moves toward the side of the adjustment component 73, the telescopic rod 726 is pulled to extend. Then, the two XY-axis moving platforms 5 and each robotic arm 6 begin to adjust respectively. Each robotic arm 6 drives the welding mechanism 7 at its end to position close to the docking point of the two equipments. After positioning, welding begins. When encountering a place that cannot be welded directly, the rotating nozzle 737 is rotated to cooperate with the universal joint 738, thereby driving the tungsten electrode 2 739 fixedly connected to the connecting rod 7310 to rotate, thereby completing the adjustment of the welding angle of the tungsten electrode 2 739.
