Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to solve the technical problems that the existing brazing tooling has a narrow application range when used, and the vacuum brazing of different styles of high-voltage battery cooler assemblies requires frequent replacement of different brazing tooling, which makes the brazing tooling inconvenient to use and the brazing efficiency low, please refer to Figure 1-Figure 6 , this embodiment provides the following technical solutions:

[0025] A brazing tool for a high-voltage battery cooler assembly includes a base plate 1, on which are arranged symmetrically distributed side positioning plates 2, on which are arranged front positioning plates 3 and rear positioning plates 4, wherein the high-voltage battery cooler assembly to be brazed is positioned in all directions by means of the side positioning plates 2, the front positioning plates 3 and the rear positioning plates 4.

[0026] In this embodiment, a first transmission screw 11 and a second transmission screw 12 are disposed on the inner side of the base plate 1 . The first transmission screw 11 and the second transmission screw 12 are connected via a coupling, and a driving handle 111 is installed at the end of the first transmission screw 11 .

[0027] It should be noted that the first transmission screw 11 and the second transmission screw 12 are both mounted on the base plate 1 through bearings.

[0028] By adopting the above technical solution, the first transmission screw 11 is driven to rotate by the driving handle 111. Since the first transmission screw 11 and the second transmission screw 12 are connected by a coupling, the first transmission screw 11 drives the second transmission screw 12 to rotate during the rotation process.

[0029] In this embodiment, the first transmission screw 11 and the second transmission screw 12 are both threadedly connected with the side positioning plate 2 , the side positioning plate 2 passes through the surface of the bottom plate 1 , and the side positioning plate 2 is located on the outside of the bottom plate 1 .

[0030] It should be noted that the surface of the bottom plate 1 is provided with a guide groove for the lateral movement of the side positioning plate 2 , wherein the side positioning plate 2 can be limited by the provided guide groove to ensure the lateral movement of the side positioning plate 2 .

[0031] It should be noted that the thread directions of the first transmission screw 11 and the second transmission screw 12 are opposite, so that when the first transmission screw 11 and the second transmission screw 12 rotate, they can drive the two side positioning plates 2 to move toward or in the opposite direction, thereby adjusting the position of the side positioning plates 2, and then better positioning the high-voltage battery cooler assembly to be brazed.

[0032] In this embodiment, the front positioning plate 3 and the rear positioning plate 4 are respectively sleeved on the front end and the rear end of the side positioning plate 2 , and the front positioning plate 3 and the rear positioning plate 4 are both fixed to the side positioning plate 2 through the positioning rod 5 .

[0033] It should be noted that the front positioning plate 3 and the rear positioning plate 4 can be moved forward and backward on the side positioning plate 2 to achieve position adjustment of the front positioning plate 3 and the rear positioning plate 4. After the positions of the front positioning plate 3 and the rear positioning plate 4 are adjusted, the front positioning plate 3 and the rear positioning plate 4 can be fixed on the side positioning plate 2 through the positioning rod 5, and then the high-voltage battery cooler assembly to be brazed can be fully positioned through the side positioning plate 2, the front positioning plate 3 and the rear positioning plate 4, so that the brazing tooling is convenient to use and the brazing efficiency can be improved.

[0035] It should be noted that when adjacent side positioning plates 2 move toward or in opposite directions, the adjacent side positioning plates 2 can move in the strip-shaped through grooves 6, so that the adjacent side positioning plates 2 can position high-voltage battery cooler assemblies of different sizes, wherein, when the front positioning plates 3 and the rear positioning plates 4 are mounted on the side positioning plates 2, the front positioning plates 3 and the rear positioning plates 4 can also move on the side positioning plates 2, so that the front positioning plates 3 and the rear positioning plates 4 can position high-voltage battery cooler assemblies of different sizes.

[0036] In this embodiment, the side positioning plates 2 , the front positioning plates 3 and the rear positioning plates 4 are all provided with positioning grooves 7 for the positioning rods 5 to be inserted into, wherein the positioning rods 5 and the positioning grooves 7 match each other.

[0037] It should be noted that after the front positioning plate 3 and the rear positioning plate 4 are adjusted in position on the side positioning plate 2, the front positioning plate 3 and the rear positioning plate 4 can be fixed on the side positioning plate 2 by the positioning rod 5, wherein, by inserting the positioning rod 5 into the positioning grooves 7 at different positions on the side positioning plate 2, the front positioning plate 3 and the rear positioning plate 4, the side positioning plate 2, the front positioning plate 3 and the rear positioning plate 4 can perform all-round positioning of high-voltage battery cooler assemblies of different sizes, and the application range is wide. For vacuum brazing of different styles of high-voltage battery cooler assemblies, there is no need to frequently replace different brazing tools, which makes the brazing tools easy to use and can improve the brazing efficiency.
