[0026] Specifically, the driving part includes a rotating motor 8, and mounting seats 4 are fixedly installed on both sides of the bottom of the gantry frame 2. The rotating bar 5 is rotatably connected to the mounting seat 4 through a rotating shaft. The rotating motor 8 is fixedly installed on the mounting seat 4 and the output shaft of the rotating motor 8 is fixedly connected to one end of the rotating shaft. The rotating motor 8 is started to make the output shaft of the rotating motor 8 rotate clockwise or counterclockwise, which is convenient for driving the rotating bar 5 to rotate clockwise or counterclockwise, thereby driving the manipulator 6 to rotate inward or outward, so as to make the welding gun 7 more flexible to meet the welding needs at different positions.

[0027] Specifically, it also includes a lifting mechanism for driving the gantry frame 2 to lift and lower, the lifting mechanism includes a vertical slide rail 3 fixedly installed on the bottom plate 1, a lifting slider 10 is slidingly matched with the guide on the vertical slide rail 3, the lifting slider 10 is fixedly connected to the bottom of the gantry frame 2, and a feed drive component for driving the lifting slider 10 to lift and lower is provided on the vertical slide rail 3. The feed drive component is used to facilitate driving the lifting slider 10 to move up or down on the vertical slide rail 3, thereby driving the gantry frame 2 to lift and lower, thereby adjusting the height of the double-station welding structure.
