[0027] See also Figures 1 to 2 As shown in the embodiments of this application, this application provides an automatic welding device for gas metal arc welding, including: a workpiece to be welded 1, a welding torch device 2, and a sliding displacement mechanism 5; wherein, the workpiece to be welded 1 includes at least a first side plate 11 for supporting and fixing the welding torch device 2 and the workpiece to be welded; the first end 21 of the welding torch device 2 is a welding end, which penetrates the first side plate 11 and extends into the internal space of the workpiece to be welded 1; the first end 21 of the welding torch device 2 integrates an image acquisition device 3 for acquiring image information of the interior of the workpiece to be welded 1 in real time. By integrating the image acquisition device 3 into the welding end of the welding torch device 2, image information of the interior of the workpiece to be welded 1 can be acquired in real time. This not only helps to monitor the welding process and ensure welding quality, but also allows for fine-tuning of the welding path when necessary, thereby improving the accuracy of welding. The second end 22 of the welding torch device 2 is mechanically connected to the drive motor 4. The movement of the welding device 2 and the welding operation are realized by the drive motor, so that the welding operation can be carried out automatically, which greatly improves the welding efficiency, reduces the dependence on manual operation, and reduces the production cost of the product. Preferably, the drive motor 4 includes, but is not limited to, welding equipment, wire feeding equipment, etc.

[0028] In addition, the sliding displacement mechanism 5 includes a slider 51 fixedly connected to the workpiece 1 to be welded, and a slide rail 52 on which the slider 51 slides. The precise movement of the welding device 2 inside the workpiece 1 is achieved by the sliding of the slider 51 on the slide rail 52.

[0029] In this embodiment, a switch 7 is provided at the connection between the second end 22 of the welding torch device 2 and the drive motor 4 to control the movement of the support frame 6. Integrating the switch 7 at the connection between the second end 22 of the welding torch device 2 and the drive motor 4 results in a higher degree of integration and a more compact structure for the entire welding device. This not only helps reduce the manufacturing cost of the equipment but also improves its reliability and stability.
