[0019] Refer to Figure 1 - Figure 2, the present utility model provides a technical solution: a star frame welding tooling, which includes a welding table 1. There is an aluminum core 2 at the center of the welding table 1. A welding platform inner diameter ring 3 is installed on the top of the welding table 1. Multiple mutually symmetrical moving tracks 4 are arranged outside the welding platform inner diameter ring 3 of the component. A track slider 5 is installed on the surface of the moving track 4. A star frame star arm 6 is arranged on the track slider 5. The star frame star arm 6 is provided with screw holes that are equidistant and matched with the track slider 5. By means of bolts, the star frame star arm 6 is connected to the track slider 5. After the moving track 4 installs the track slider 5, the star frame star arm 6 can be placed on the track slider 5, which is convenient for the user to connect the star frame star arm 6 and the track slider 5 through bolts. The track slider 5 can support the star frame star arm 6 and move the star frame star arm 6 at the same time, which is convenient for moving the star frame star arm 6 and then fitting the star frame star arm 6 to the aluminum core 2, so as to facilitate welding the star frame star arm 6 and the aluminum core 2 together. Moreover, multiple moving tracks 4 are provided, which can adapt to star frame star arms 6 with different equal division distributions.
[0020] Refer to Figure 1 - Figure 2 , in a preferred embodiment, a fixing ring 7 is provided on the top of the welding table 1. One end of the star frame star arm 6 is placed outside the aluminum core 2, and the other end is threadedly connected to the fixing ring 7. The fixing ring 7 can be sleeved on the surface of the star frame star arm 6, and the star frame star arm 6 can be limited after the fixing ring 7 is installed on the star frame star arm 6, avoiding the situation of the star frame star arm 6 sliding. A lifting ring 8 is installed on the top of the welding table 1. Multiple groups of lifting rings 8 are provided. After the lifting rings 8 are installed, it is convenient for the user to use a lifting device to hook the lifting rings 8, so as to facilitate lifting the welding table 1 for transportation.

Four first tracks 41 are provided and are equally spaced and installed on the top of the welding table 1. A number of second tracks 42 are provided. The second tracks 42 are located inside the first tracks 41. The included angle between the second track 42 and the first track 41 is 30°, and the included angle between the second tracks 42 is 15°. Two groups of track sliders 5 are provided, and the two groups of track sliders 5 are arranged dispersedly. A card slot is opened on the top of the track slider 5.

Subsequently, according to the required welded star frame star arms 6, they are evenly placed in the card slots on the track sliders 5 and are dispersed to both sides of the star frame star arms 6 according to the two groups of track sliders 5. Then, bolts are used to connect the star frame star arms 6 to the track sliders 5, and the star frame star arms 6 are moved so that the inner sides of the star frame star arms 6 are fitted to the surface of the aluminum core 2. Then, the fixing ring 7 is sleeved on the outer sides of the star frame star arms 6, and bolts are used to install the fixing ring 7 into the screw holes on the outer sides of the star frame star arms 6. Furthermore, the fixing ring 7 restricts the star frame star arms 6, avoiding the sliding of the star frame star arms 6 when welding the star frame star arms 6 to the aluminum core 2, and can solve the problem of equal division during on-site installation of the product.
