Problems solved by technology
Therefore, after welding the upper grille strips and the frame of the grille, it is necessary to clamp the frame, grille and tooling on the positioner, and then weld the lower grille strips and the frame after turning 180°; The plate grid needs to be disassembled and assembled once on the positioner. The operation steps are cumbersome, the welding work efficiency is low, and the number of positioners is limited, which cannot meet the mass production of products. Using the positioner for a long time will also cause great damage to the equipment. big loss
[0003] Therefore, there is a need for a skirt grid welding tool that can change the welding angle to solve the problem of changing the welding angle between the grid and the frame

The invention discloses a rotary tool for welding a skirt board grating of a rail vehicle. The rotary tool comprises a clamp bracket and a clamp for fixing the grafting and a skirt board frame, wherein the clamp comprises a rectangular supporting frame, a chuck and a supporting plate; a group of opposite frame plates of the rectangular supporting frame are respectively fixed on the clamp bracket through a pin shaft; and the rectangular supporting frame can freely rotate around the pin shaft, and the clamp bracket is also provided with a lock device for fixing the rectangular supporting frame. According to the tool disclosed by the invention, the skirt board frame and the grafting are fixed on the clamp according to size and position of the finished skit board through the rectangular supporting frame, the supporting plate and the chuck; and the rectangular supporting frame and the supporting plate can limit deformation of the skirt board during welding so as to ensure the size of the welded skirt board. Meanwhile, the lock device of the tool is loosened, and the clamp can be fixed on the clamp bracket after the front and reverse sides are exchanged, so that welding of the front side and back side of the grafting and the skirt board frame can be simultaneously finished on the tool, and the tool welding efficiency of the skirt board frame and the grafting can be improved.
Description
technical field [0001] The invention relates to a tooling, in particular to a tooling for rail vehicle skirt grille welding. Background technique [0002] The aluminum alloy apron for rail vehicles is composed of a frame and a curved grille. The curved grille is composed of upper and lower layers of grille bars. It needs to be welded to the frame. Therefore, after welding the upper grille strips and the frame of the grille, it is necessary to clamp the frame, grille and tooling on the positioner, and then weld the lower grille strips and the frame after turning 180°; The plate grid needs to be disassembled and assembled once on the positioner. The operation steps are cumbersome, the welding work efficiency is low, and the number of positioners is limited, which cannot meet the mass production of products. Using the positioner for a long time will also cause great damage to the equipment. Big loss. [0003] Therefore, there is a need for a skirt grid welding tool that can ...
