At this time, drive the horizontal moving rod 515 on the adjusting slide 518 to move towards each other through the linkage rod 517, so that the clamping soft plate 530 on the adjusting slide 518 clamps and fixes the bottom plate of the battery box. When the clamping soft plate 530 touches the bottom plate of the battery box, the bottom plate is clamped and fixed through the adaptive movement of the clamping soft plate 530. Step 3: Then insert the vertical plate into the middle position between the two vertical limiting plates 508.

8. The automatic welding equipment for a new energy storage chassis according to claim 7 is characterized in that: The tooling support frame (3) is provided with four circular holes on both sides, and the insides of the two circular holes are connected to angle adjustment columns (6) through bearings, one end of the angle adjustment column (6) is fixedly connected to one side of the welding tooling platform (4), and one side of the tooling support frame (3) is fixedly connected to a drive motor (8), and the drive end of the drive motor (8) and the outside of one of the angle adjustment columns (6) are fixedly connected to a pulley two, and the outsides of the two pulleys two are slidably connected to the same belt one (7).

9. The automatic welding equipment for a new energy storage chassis according to claim 8 is characterized in that: An automatic welding gun body (2) is arranged on one side of the tooling support frame (3), and a welding box (1) is arranged on one side of the tooling support frame (3).

10. A method for using an automatic welding device for a new energy storage chassis, using the automatic welding device for a new energy storage chassis according to claim 9, characterized in that: The steps include: Step 1: When welding the battery box plate, first place the bottom plate on the welding tooling platform (4), and then start the second screw motor (525) according to the size of the plate, and drive the bidirectional screw (524) through the second screw motor (525) to move the movable slide (528) inside the second slide groove (526) on the horizontal movable rod (515), so that the clamping soft plate (530) on the movable slide (528) is adjusted to one side of the edge of the plate; Step 2, then start the winding motor (522), and use the winding disk (521) on the winding motor (522) to wind up the winding rope (519), and at this time, drive the horizontal moving rod (515) on the adjusting slide (518) to move in opposite directions through the linkage support rod (517), so that the clamping soft plate (530) on the adjusting slide (518) clamps and fixes the bottom plate of the battery box, and when the clamping soft plate (530) collides with the bottom plate of the battery box, the bottom plate is clamped and fixed by the clamping soft plate (530) through adaptive movement; Step 3, then insert the vertical plate into the middle position of the two vertical limit plates (508), at this time, the vertical plate is self-adaptively limited by the movable top column 1 (510), so that the limit roller (513) limits and clamps the vertical plate, after the vertical plate and the bottom plate are welded, start the electric drive rod (504), and drive the lifting plate (509) through the electric drive rod (504) to make the vertical limit plate (508) rise and separate from the welded vertical plate, and then start the screw motor 1 (507), the screw motor 1 (507) drives the adjustment screw (506) to rotate, so that the vertical limit plate (508) on the adjustment slider (505) moves to the next welding point, and then reset the vertical limit plate (508) and reinsert the vertical plate for welding.
