The first driver 61 is installed on the rear fixing plate 11, and the rear fixing plate 11 is connected to the mounting plate 30. Under the transmission of the first driver 61, the two slide plates 40 are driven to move relative to or away from each other to simultaneously change the distance between the welding device 50 and the workpiece fixing panel 20.

[0040] One welding device 50 is slidably mounted on one slide plate 40. Specifically, the welding device 50 is mounted on the slide plate 40 via a first guide rail 101, and the sliding direction of the welding device 50 is a vertical direction. Two welding devices 50 are respectively located on the left and right sides of the workpiece fixing panel 20 to weld the workpiece on both sides.

[0043] Driven by the first driver 61, the gear 63 is driven to transmit, and then the two slides 40 are driven to move relative to or away from each other, so that the two welding devices 50 are synchronously close to or away from the distance between the workpiece fixing panel 20. The second driver 62 can change the planar position of the welding device 50 relative to the workpiece fixing panel 20, and then the workpiece can be welded or the welding position can be changed, which can effectively improve the welding quality and work efficiency and help students learn the skills of double-sided welding.
