[0004] This utility model achieves the above-mentioned objective through the following technical solution: a precision machining positioning device for multi-curved irregular steel, comprising a pneumatic suction cup, a ball head, an arc plate, a U-shaped component, a worm gear, and a worm. The pneumatic suction cup is fixedly connected to one end of a channel located on the ball head, and the ball head is rolled and installed inside a connecting ring. The surface of the connecting ring is welded and fixed to one end of the arc plate, and the middle part of the arc plate is welded inside the U-shaped component. The worm gear located at the bottom of the U-shaped component meshes with the worm, and a rotating rod is installed at one end of the worm.

[0005] Preferably, a threaded tube is welded to the other end of the channel on the ball head, and the threaded tube is fixedly connected to the arc-shaped hole on the arc plate by a nut.

[0006] Preferably, one end of the threaded tube is connected to an external pneumatic system via the tube body.

[0007] Preferably, the worm gear is rotatably mounted inside the carrier frame, and one side of the carrier frame is rotatably connected to the middle of the rotating rod via a bearing.

[0008] Preferably, the bottom of the carrier is fixed on the tooling table.

[0009] Preferably, the suction contact surface of the pneumatic suction cup makes full contact with the surface of the multi-curved irregular steel through deformation.
