[0025] Please refer to Figure 4 The base 1 includes a base 101, and a rotating disk 106 is rotatably connected to the top of the base 101. The rotating disk 106 is sleeved in a concave cavity at the top of the base 101, and the rotating disk 106 is driven to rotate by a driving component. Specifically, the driving component includes a motor 103, which is mounted on the base 101. The driving end of the motor 103 drives the rotating disk 106 to rotate through a reducer 104, and the rotating component 2 is connected to the rotating disk 106. In a specific embodiment, the rotating disk 106 is annular, and the inner ring is provided with a rack meshing with a gear 105, and the gear 105 is connected to the driving end of the reducer 104.

[0026] The motor 103 drives the gear 105 to rotate through the reducer 104, and the meshing action of the gear 105 and the rack is used to rotate the rotating disk 106. Since the rotating assembly 2 is connected to the rotating disk 106, the rotating assembly 2 can drive the welding station thereon to rotate under the drive of the motor 103, thereby adjusting the position of the welding machine station. Furthermore, through the meshing action between the gear 105 and the rack, the rotation angle can be accurately controlled, thereby improving the accuracy of the welding station adjustment.

The motor 103 is located inside the safety box 202. The protective plate 203 is used to isolate the two welding stations to avoid mutual influence during welding. The safety box 202 and the connection box 201 cover the drive assembly and the base 1, which can protect the drive source and prevent the drive assembly from being exposed and affecting its service life.

The motor 2 301 drives the tooling fixing plate 1 304 to rotate through the reducer 2 303, thereby driving the workpiece and the tooling fixing plate 2 403 to rotate, realizing the self-rotation of the workpiece to adjust the workpiece to the required welding angle.

[0032] A handle 6 is installed on the side wall of the connecting plate 5 between the active mechanism 3 and the driven mechanism 4, and the handle end of the handle 6 is in an arc shape. The handle 6 drives the rotating assembly 2 to rotate, so that manual adjustment can be achieved, and the arc-shaped handle 6 meets ergonomics and is conducive to improving the comfort of the user.

[0033] Working principle: When the welding positioner is used, the two ends of the workpiece to be welded are connected to the tooling fixing plate 1 304 and the tooling fixing plate 2 403 respectively, and then the motor 103 drives the gear 105 to rotate through the reducer 104, and the meshing action of the gear 105 and the rack is used to rotate the rotating disk 106, thereby driving the welding station on the rotating component 2 to rotate, thereby realizing the adjustment of the welding machine station position.
