[0015] (Three) beneficial effects

[0016] Compared with the prior art, the utility model provides a kind of welding car for aluminum alloy subway chassis processing, with following beneficial effects:

[0017] 1. This utility model sets up a base plate, a main plate, and an installation structure at the upper part of the main plate. A welding gun is installed on the installation structure, and the entire welding vehicle is moved by the rotation of the wheels and the base plate. The welding gun on the installation structure is used to weld the subway underframe, thereby reducing the contact between personnel and the welding position, ensuring the safety of the operators, and facilitating the use when welding the subway underframe.

[0018] 2. This utility model, by setting up an installation structure, allows for the simultaneous welding of the symmetrical structure of the subway underframe by rotating the main body plate and the mounting pipe.

To achieve the desired position, the installation tube is rotated to change the orientation of the installation frame. Bolts are inserted into the second positioning hole to fix the position of the installation tube. To fix the height of the installation frame and welding torch, the installation rod is pulled out of the installation tube according to the required welding height. A motor on the rotating block drives the fixed block to rotate, thereby changing the longitudinal angle of the welding torch. A motor on the moving frame drives the rotating block to rotate, changing the lateral angle of the welding torch. A threaded rod on the installation frame rotates the moving frame, thereby changing the extension distance of the welding torch. This facilitates welding at the required position and allows for easy adjustment of the entire welding vehicle as needed. Attached Figure Description
