[0022] like Figure 1-3 As shown, an automatic welding machine includes a working platform 1, which provides a stable foundation for the entire welding process. A support column 2 is provided above the working platform 1, and a support plate 3 is provided on the top of the support column 2. The structural design of the support column 2 and the support plate 3 ensures the stability of the welding equipment, thereby ensuring the stability and safety of the welding process. A rotating rod 4 is provided in the middle of the support plate 3, and a pointed top is provided at the bottom of the lower part of the rotating rod 4. A fixing piece is provided on the side below the rotating rod 4, and a welding gun 5 is provided on the side of the fixing piece. The welding gun 5 is arranged at an inclined angle with the fixing piece. The existence of the fixing piece ensures the stability of the welding gun 5 during the welding process and prevents it from shaking or moving, thereby affecting the welding quality. The interior of the rotating rod 4 is a hollow structure 6, and the middle side of the rotating rod is provided with a side groove 7 that penetrates the hollow structure 6. A welding handle wire 8 is provided in the hollow structure 6, and one end of the welding handle wire 8 is connected to the welding gun 5. The design of the rotating rod 4 enables the welding gun 5 to weld at different angles and positions. The hollow structure 6 and the side groove 7 inside the rotating rod 4 provide space for the layout of the welding handle wire 8, so that the welding handle wire 8 can smoothly pass through the inside of the rotating rod 4 and connect to the outside through the side groove 7. This design not only reduces the interference and entanglement of the welding handle wire 8, but also improves the flexibility of the welding process. The pointed top is designed to support the workpiece to be welded below. The welding gun 5 is set at an inclined angle with the fixing part, which is conducive to the welding gun 5 to better adapt to the shape and angle of the workpiece during the welding process, thereby improving the welding quality and efficiency.

[0023] During operation, the welding handle wire 8 is connected to the welding gun 5 through the hollow structure 6 and the side groove 7 inside the rotating rod 4. The welding power source provides the required electrical energy to the welding gun 5 through the welding handle wire 8. When the welding gun 5 contacts the workpiece, the metal on the surface of the workpiece is heated through the potential difference, so that the welding joint is melted and the welding process is realized.

[0024] At the same time, the structural design of the rotating rod 4 and the supporting plate 3 enables the welding gun 5 to rotate and tilt to meet the welding requirements of different angles and positions. The welding gun 5 revolves around the welding workpiece. This automated welding method greatly improves welding efficiency, reduces the need for manual operation, reduces labor costs, and avoids welding errors caused by human factors, thereby improving the stability of welding quality.

[0025] Combination Figure 1-2In this embodiment, a gear box 9 is provided above the support plate 3, and a first drive motor 10 is provided above the gear box 9. The output end of the first drive motor 10 extends into the gear box 9 and is connected to a drive gear 11. A transmission gear 12 is provided above the rotating rod 4, and the drive gear 11 is meshed with the transmission gear 12. The first drive motor 10 drives the drive gear 11, which in turn drives the transmission gear 12 and the rotating rod 4 to rotate, thereby realizing the automatic rotation and positioning of the welding gun 5. This greatly reduces manual operation and improves the degree of automation of the welding process. The first drive motor 10 can accurately adjust the rotation speed and rotation angle according to a preset program or a real-time control signal, thereby realizing precise control of the position of the welding gun 5. This helps to ensure the accuracy and consistency of the welding process.

[0026] Combination Figure 2 and Figure 4 A cable adjustment mechanism is also fixed above the gear box 9. The cable adjustment mechanism includes a support seat 13. A first adjustment wheel 14 and a second adjustment wheel 15 are provided on the front of the support seat 13. The welding handle wire 8 passes through the first adjustment wheel 14 and the second adjustment wheel 15. A second drive motor is provided on the back of the support seat 13. The output end of the second drive motor is connected to the first adjustment wheel 14. The cable adjustment mechanism can realize automatic adjustment of the welding handle wire 8 by driving the first adjustment wheel 14 by the second drive motor. This automatic adjustment function can adjust the length and tension of the welding handle wire 8 in real time according to the position and angle of the welding gun 5, ensuring smooth welding. The cable adjustment mechanism effectively manages the welding handle wire 8 through the first adjustment wheel 14 and the second adjustment wheel 15 to ensure that the welding handle wire 8 maintains appropriate tension and position during welding. This helps to reduce the wear and entanglement of the cable, extend the service life of the welding handle wire 8, and also improve the stability and reliability of the welding operation.

[0027] The fixing member in this embodiment includes a fixing seat 16, a first mounting plate 17 and a second mounting plate 18. The first mounting plate 17 is provided at the bottom of the fixing seat 16. A dovetail-shaped slide groove is provided on the first mounting plate 17, and a matching dovetail-shaped slide rail is provided on the second mounting plate 18, or the second mounting plate 18 is directly slidably provided inside the first mounting plate 17. A sliding lock groove 19 is provided on the first mounting plate 17, and a sliding lock hole 20 is provided on the second mounting plate 18. The first mounting plate 17 and the second mounting plate 18 can be fixed by passing a bolt through the sliding lock groove 19 and the sliding lock hole 20. The side end of the second mounting plate 18 is connected to the welding gun 5. The two mounting plates can change the orbital diameter of the welding gun 5 and improve the scope of application.

[0028] The tip top includes a tip outer rod 21 and a tip inner rod 22. A sliding cavity 23 is provided in the middle of the tip outer rod 21. The tip inner rod 22 is slidably arranged in the sliding cavity 23. A spring 24 is connected to the top of the tip inner rod 22. The top of the spring 24 is connected to the top of the sliding cavity 23. The bottom of the tip inner rod 22 is used to resist the workpiece. During the resisting process, the tip inner rod 22 will contact or collide with the workpiece. The presence of the spring 24 can effectively reduce the impact caused by such contact or collision, and avoid damage to the welding machine or the workpiece. At the same time, the buffering effect of the spring 24 also helps to improve the stability of the welding process and ensure the welding quality. The sliding design of the tip inner rod 22 in the sliding cavity 23 enables the tip top to have a certain adaptive adjustment ability. When facing workpieces of different shapes or surfaces, the tip top can be fine-tuned as needed to better adapt to the characteristics of the workpiece and improve the accuracy and efficiency of welding.
