[0019] The clamp bracket 2 is connected to the outer pressure plate 3 through the adjusting stud 31, and an inner pressure strip 32 is distributed at the lower end of the outer pressure plate 3. The outer side of the adjusting stud 31 is connected to the synchronous clamping mechanism 4, and the synchronous clamping mechanism 4 is connected to the adjusting stud 31 through the second transmission wheel 42. The surface of the second transmission wheel 42 is connected to the first transmission wheel 41 through the transmission belt 43. The inner side of the first transmission wheel 41 is connected to the screw rod 44 through the connecting rod 45, and the surface of the screw rod 44 is connected to the inner pressure strip 32 through the driving block 33.

[0020] Working principle: First, fit the side end of the special-shaped tubular processing part with the side of the clamp bracket 2, so that the outer pressure plate 3 and the inner pressure strip 32 are distributed on the inner and outer sides of the special-shaped tubular processing part, and rotate the adjusting stud 31 to move the outer pressure plate 3 toward the outer surface of the processing part, and synchronously drive the inner pressure strip 32 to move toward the inner wall of the processing part through the synchronous clamping mechanism 4, until the outer pressure plate 3 and the inner pressure strip 32 are clamped with the inner and outer walls of the special-shaped tubular processing part, and then position welding is performed. After welding is completed, rotate the adjusting stud 31 in the opposite direction to release the clamping of the outer pressure plate 3 and the inner pressure strip 32, and control the hydraulic column 13 to pull the clamp bracket 2 to move outward, so that the metal product with positioning welding can be taken out.

[0021] In this embodiment, a separation slot 14 is provided on the upper surface of the positioning welding table 1 ; and the lower end of the positioning slide 21 is slidably connected in the separation slot 14 , and the side end of the positioning slide 21 is connected to a hydraulic column 13 .

[0022] As a preferred embodiment, the separation slide 14 facilitates the limited movement of the clamp bracket 2, so as to facilitate the separation of the welded metal products. The hydraulic column 13 pushes the positioning slide 21 to position the clamp bracket 2 at the welding position.

[0023] In this embodiment, a rotating chassis 11 is installed at the lower end of the positioning welding platform 1, and a control panel 12 is provided on the front surface of the positioning welding platform 1; and the control panel 12 is connected to a hydraulic column 13 by electric wires.
