[0032] Working principle:

[0033] The steel pipe to be welded is placed in the fixed groove 15 of the bearing plate 14 above the second pulley 12, and the steel pipe is preliminarily limited by the fixed groove 15. After the rotary motor 21 is started, the output shaft drives the first pulley 10 to rotate, the first pulley 10 is in meshing transmission with the gear groove 8 at one end of the rotating rod 7 through the fixed connection of the first gear table 11, and drives the rotating rod 7 to rotate around the rotating shaft groove 6. The rotating gear 16 on the rotating rod 7 is in meshing with the second gear table 13 in the second pulley 12, and then drives the second pulley 12 to rotate stably, so that the steel pipe on the bearing plate 14 is uniformly conveyed in the preset direction, and the continuous feeding and positioning of the steel pipe are completed. The conveying position of the steel pipe is monitored in real time by the controller 4. When the steel pipe moves to the welding station, the controller 4 sends instructions to the driving motor 17 through the data line 5, and the driving motor 17 drives the sliding shaft 18 to move transversely along the sliding groove 9 on the support 3 after being started. The sliding gear 22 on the side of the driving motor 17 is in meshing with the third gear table 20 at the lower end of the support 3, the displacement speed and stroke of the sliding shaft 18 are accurately controlled through gear transmission, and then the transverse position and welding path of the welding gun 19 are adjusted. The welding gun 19 is driven by the driving motor 17 to perform high-frequency welding on the joint of the steel pipe at the preset welding parameters, so that the welding seam is uniform, dense, and free of pores or crack defects. The high-frequency current of the welding gun 19 is dynamically adjusted by the controller 4 according to the parameters such as the material and thickness of the steel pipe, and welding state data is transmitted to the controller 4 in real time through the data line 5. The controller 4 optimizes the welding parameters in a closed loop through the built-in algorithm, for example, when an abnormal welding seam temperature is detected, the moving speed of the driving motor 17 or the output power of the welding gun 19 is automatically adjusted to maintain the stability of the welding quality. During the welding process, the second pulley 12 continuously conveys the steel pipe, and the welding gun 19 moves synchronously to realize dynamic welding and avoid uneven welding caused by stopping. After the welding of a single steel pipe is completed, the second pulley 12 continues to rotate to convey the finished steel pipe to the next process, and a new steel pipe to be welded automatically enters the welding station. The welding gun 19 is reset to the initial position under the instruction of the controller 4, and is ready for the next welding cycle. The whole process does not need manual intervention, and continuous and efficient production is realized through the programmed control of the controller 4. The device realizes the precise cooperative movement of the steel pipe conveying and the welding head through the cooperation of the gear transmission system and the pulley conveying structure; the integrated control of the controller 4 on the rotary motor 21, the driving motor 17 and the welding gun 19 ensures the adaptive adjustment of the welding parameters, significantly improves the welding efficiency and quality stability, and is suitable for high-frequency straight seam welding of steel pipes of different specifications.
