The long straight gap inside the car frame 1 can be combined with the forward mechanism 3 to realize rapid welding, and the mounting frame 2 carries the upper space translation assembly 4 and the posture adjustment mechanism 5 to move together, and cooperates with the welding mechanism 6 to perform gap welding. When welding angle irons, since the welding angle iron 710 is fixed at the corner inside the car frame 1, the welding head 63 is aligned with the right-angle transition part of the welding angle iron 710 through the posture adjustment mechanism 5, and the welding head 63 is controlled by the horizontal motor 43 and the vertical motor 46 to realize the vertical and horizontal movement of the welding head 63, so as to realize the rapid welding operation between the welding angle iron 710 and the inner wall of the car frame 1, and improve the overall stability of the welding of the car frame 1. The horizontal motor 43 and the vertical motor 46 are connected with threaded rods, and the horizontal moving frame 42 and the vertical moving frame 45 are provided with threaded sleeves inside, and the driving is realized by the mutual cooperation between the threaded rods and the threaded sleeves. The angle iron arrangement mechanism 7 moves together with the welding mechanism 6 to approach the welding part inside the car frame 1. When the welding mechanism 6 approaches the welding part under the drive of the telescopic cylinder 1 514, the telescopic cylinder 2 70 controls the welding angle iron 710 to be close to the welding part, and the adsorption magnet 713 is combined with the internal fixed adsorption of the car frame 1, and the locking connection between the moving block 72 and the side frame 781 is disconnected at the same time, and the welding head 63 is driven by the spatial translation component 4 to perform welding operation between the welding angle iron 710 and the car frame 1. Among them, the welding angle iron 710 is pushed out by the push motor 711 and the push right angle frame 79, so that the welding angle iron 710 fits with the inner wall of the car frame 1, ensuring subsequent reliable welding. After the welding is completed, the docking block 73 and the docking sleeve 74 are controlled to dock with each other again, so that the angle iron arrangement mechanism 7 is separated from the car frame 1, and the welding operation of the next part is carried out.
