[0002] A tail lift is a hydraulic lifting and loading equipment installed at the rear of a vehicle, powered by an on-board battery. A truck equipped with a tail lift is not restricted by site, equipment, and manpower when loading and unloading goods. During the production process of a car tail lift, different components and plates need to be welded together.

[0003] The utility model with the existing authorization announcement number CN217019174U discloses a welding tool for automobile tailgate production, including a base: the four corners of the lower surface are provided with support columns, the horizontal slide groove on the left side of the upper surface of the base is slidably connected with the slider at the bottom end of the mounting plate, the rear side of the upper surface of the mounting plate is rotatably connected with a rotating rod through a bearing, the outer arc surface of the rotating rod is provided with a baffle, the front side surface of the mounting plate is symmetrically provided with threaded grooves, the inside of the threaded grooves are threadedly connected with a threaded rod 1, the front end of the threaded rod 1 is rotatably connected with a fixing plate, and the lower end of the fixing plate is connected to the upper surface of the mounting plate The surface is slidingly connected, and the position adjustment mechanism includes a longitudinal slide plate, gear one, a threaded rod, a Z-shaped rod and gear three. The threaded rod is rotatably connected to the longitudinal slide groove at the right end of the base through a bearing, and the middle part of the threaded rod is threadedly connected with the longitudinal slide plate. The right end rotating hole on the front side of the base is rotatably connected to the rotating shaft on the rear side of gear one, and the rear end of the rotating shaft is fixedly connected to the front end of the threaded rod. The right end circular hole on the front side of the base is rotatably connected to the pin shaft on the rear side of gear three. Gear three is meshingly connected to gear one, and a Z-shaped rod is provided at the center of the front side of gear three to adjust the longitudinal position of the plate.

[0004] By adopting the above technical solution, the telescopic end of the electric push rod drives the mounting plate to slide to the right along the horizontal slide groove, so that the lateral distance between the two plates is reduced, thereby adjusting the position of the plates so that the positions to be welded correspond to each other, which is convenient for subsequent welding. However, when welding the tail plate, the above technical solution is not convenient for handling the smoke generated by welding, so that the smoke is easy to fly everywhere, thereby affecting the health of personnel and the environment. In addition, after welding, personnel are required to carry the welded tail plate, which increases the labor intensity of the staff and reduces the welding efficiency, making it less practical.

[0005] Therefore, we propose a welding tool for automobile tail plate production to solve the above problems. Utility Model Content
