A rubber pad 54 is fixedly installed inside the L-shaped sliding block 53. A screwing block 55 is fixedly installed on the left side of the threaded rod 52.

[0021] The positioning mechanism 6 includes a column 61, an arc plate 62, a U-shaped plate 63, a threaded rod 64, a pressing block 65, and a handle 66. The column 61 is fixedly installed on the top of the L-shaped sliding block 53. The arc plate 62 is fixedly installed on the right end of the outer peripheral wall of the column 61. The U-shaped plate 63 is rotatably installed on the arc plate 62. A threaded rod 64 with one end penetrating through and extending into the U-shaped plate 63 is threadedly connected to the left side of the U-shaped plate 63. The pressing block 65 is fixedly installed on the right side of the threaded rod 64, and the handle 66 is fixedly installed on the left side of the threaded rod 64.

[0022] Specifically, when welding structural components, loosen the threaded rod 52. The threaded rod 52 drives the L-shaped sliding block 53 to move the arc plate 62 to the right to its limit position. Insert the structural component to be welded into the arc plate 62, flip the U-shaped plate 63 to the right, and twist the threaded rod 64 to move the pressing block 65 downward to position the structural component.

[0027] The working principle of the above embodiments is as follows:

[0028] (1) Place the chassis to which the structural components are to be welded into the circular placement groove 3, and make the locking block 4 engage in the hole of the chassis to position the chassis.

[0029] (2) Loosen the threaded rod 52. The threaded rod 52 drives the L-shaped sliding block 53 to move the arc plate 62 to the right limit position. Insert the structural element to be welded into the arc plate 62, flip the U-shaped plate 63 to the right, and twist the threaded rod 64 to move the pressing block 65 downward to position the structural element.

[0030] (3) Welders use low heat input welding equipment to perform welding operations on structural components;

[0031] (4) After the current structural element is welded, loosen the threaded rod 64, flip the U-shaped plate 63 to the left, turn the threaded rod 52 to drive the arc plate 62 to detach from the welded structural element, rotate the disk 2 clockwise, and wait for the welded structural element to move to the indicator block 11 to position the new structural element. Repeat steps (2) and (3) to weld the new structural element onto the disk. Repeat this process until all structural elements are welded, and the required magnesium alloy array can be obtained.
