A ring-shaped distributed bottom support unit 2 is installed on the top of the base 1. Two adjustable temperature control units 3 are fixedly installed on the bottom support unit 2. Electric-permanent magnet units 4 distributed in a ring are fixedly connected to the outer sides of the two adjustable temperature control units 3. A plurality of side pressing units 5 are fixedly installed on the base 1, and the side pressing units 5 and the bottom support unit 2 are arranged at intervals
[0021] In the present utility model, the base 1 serves as the support of the device. During use, the battery water-cooled plate and the battery pack are combined and placed on two adjustable temperature control units 3. Then, the electro-permanent magnet unit 4 is activated to adsorb and fix the bottom of the combination of the water-cooled plate and the battery pack. Subsequently, the side pressing units 5 around are activated to press the combination of the water-cooled plate and the battery pack, achieving overall fixation. Then, the adjustable temperature control unit 3 is activated to heat the combination of the water-cooled plate and the battery pack and maintain it at 70°C. Then, friction stir welding is carried out. Since the product is preheated before welding, during friction stir welding, the welding thermal deformation is greatly reduced. After welding, since the product has been in a constant temperature state of 70°C, the post-weld shrinkage is also greatly reduced. Therefore, the product quality has been qualitatively improved, thus realizing that the device has the advantages of reducing the temperature difference before and after welding, reducing springback deformation, and improving welding quality, and solving the problems of large welding deformation and unstable quality in the prior art. The conventional method is to support at the bottom, tighten around, press the weld bead everywhere, and open the timing during welding. Although it can meet the welding requirements, due to the excessive temperature difference before and after welding, the welding deformation quality fluctuates, and the product quality fails to meet the standards frequently occur.
