[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model;

[0024] Please refer to Figures 3 to 6, in the present utility model: a friction stir welding tooling for a battery box that can be used in both positive and negative directions, includes a bottom plate 1, on the top of the bottom plate 1, there are multiple brackets 2 and an inner support positioning 3. A plurality of corresponding and adapted mounting holes are provided on the bottom plate 1, the multiple brackets 2, and the inner support positioning 3. The inner support positioning 3, the bottom plate 1, and the multiple brackets 2 are all fixed through the cooperation of bolts and the mounting holes. Multiple upper pressing mechanisms 5 and side pressing mechanisms 4 are respectively installed on the multiple brackets 2; the side pressing mechanism 4 includes a base 401, corresponding and adapted locking holes are provided on the base 401 and the bracket 2, and the base 401 and the bracket 2 are fixed through the cooperation of screws and the locking holes. An electric push rod 402 fixedly connected thereto is inserted through the base 401; the upper pressing mechanism 5 includes a mounting frame 501, corresponding and adapted round holes are provided on the mounting frame 501 and the bracket 2, and the mounting frame 501 and the bracket 2 are fixed through a screw rod and the round holes. A slider 502 slidably connected thereto is sleeved on the mounting frame 501, and a pressure rod 503 threadedly connected thereto is inserted through the slider 502.

[0025] In the present utility model, when welding a product (as shown in Figures 1-2 ), first, multiple product parts are attached to the inner support positioning 3. The inner support positioning 3 can support and position multiple products. After the parts are orderly attached to the inner support positioning 3, the assembly of the product is completed. Then, the user turns on the electric push rod 402, and the electric push rod 402 will press the parts against the inner support positioning 3 to complete the side fixing of the parts. Then, the user rotates multiple pressure rods 503. The pressure rods 503 will descend until they contact the parts, and then the pressure rods 503 will press the parts against the top of the inner support positioning 3 to complete the clamping of the parts. At this time, the worker manually welds the vertical surface well. Then, the worker leaves the working area, and turns on the friction stir welding torch to weld the eight front-side welds firmly, thus completing the welding treatment on the outside of the product. After the welding process is completed, rotate the screw rods on each bracket 2 to remove the brackets 2 from the bottom plate 1. Then, the product can be removed from the inner support positioning 3. Then, rotate the screw rod on the inner support positioning 3 to remove the inner support positioning 3, and the components on the top of the bottom plate 1 can be completely removed. Then, the user rotates and removes the screws on the base 401 in the side pressing mechanism 4, and the base 401 together with the electric push rod 402 can be removed. Then, distribute the base 401 around the top of the bottom plate 1, use screws to pass through the base 401 and insert them into the threaded holes provided on the bottom plate 1 and rotate, and the base 401 can be fixed on the top of the bottom plate 1. At this time, multiple electric push rods 402 will be distributed around the base 401. Then, turn the product over and place it on the tooling, and turn on multiple electric push rods 402 at the same time to position and fix the flipped product. Then, use friction stir welding to weld the reverse-side welds, thereby realizing the processing of the inner side and the surface of the product.

[0026] Please refer to Figure 5, wherein: a buffer pad 6 is fixedly connected to the bottom end of the compression bar 503, and the buffer pad 6 is a rubber layer.

[0027] In the present utility model, the buffer pad 6 can increase the friction force to improve the downward pressure stability, and at the same time, it can reduce wear and improve the service life of the device.

[0028] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
