The angle sensor 16 installed on the supporting shell 1 is used to detect the actual angle of the rotating disk 2. The position of the rotating disk 2 can be monitored in real time to ensure that it accurately corresponds to the predetermined program. By precisely controlling the angle of the rotating disk 2 and monitoring it, the welding quality and product consistency can be improved.

The positioning plates 15 are of a right-angled triangle structure. Four positioning plates 15 are provided and are symmetrical with respect to the center of the rotating disk 2. The positioning plates 15 are slidably connected to the movable grooves 17, and the positioning plates 15 are threadedly connected to the bidirectional screw 3.

[0027] It should be noted that the two mutually perpendicular bidirectional screws 3 of the utility model are staggered with each other, and the two mutually perpendicular movable slides can provide adjustment of the X-axis and the Y-axis. The positioning plate 15 can be moved to the center of the rotating disk 2 during single-angle welding, which is convenient for the placement of the box. When the four positioning plates 15 are adjusted outward, the box can be placed in the space surrounded by the positioning plates 15, so that the four sides of the box are in contact with the oblique edges of the positioning plates 15, and are fixed by squeezing the opposite sides. The outer sides of the rotating disk 2 corresponding to the movable slides 17 are provided with scale lines. By rotating the bidirectional screws, the position of the positioning plates can be accurately adjusted to meet different work requirements.
