[0015] In conjunction with the accompanying drawings, the utility model includes a base 1, on which two U-shaped frames 2 with openings facing upward are fixed, the two U-shaped frames 2 are aligned left and right and arranged at intervals, and the lower end of each U-shaped frame 2 is fixedly connected to the base 1 via a supporting column 3, and each U-shaped frame 2 is provided with a clamping plate 4, the clamping plate 4 is parallel to the front and rear side walls of the U-shaped frame 2, and a compression spring 5 is installed between the clamping plate 4 and the front wall of the U-shaped frame 2, the lower end of the clamping plate 4 is in contact with the bottom of the U-shaped frame 2 and can slide back and forth, the two sections of material to be welded are placed in the two U-shaped frames 2 respectively, and the clamping plate 4 presses the material against the rear side wall of the U-shaped frame 2 under the action of the compression spring 5, and since the two U-shaped frames 2 are aligned left and right, the two sections of material are automatically aligned left and right after being clamped.

[0016] Two movable seats 6 are installed on the base 1. The two movable seats 6 are symmetrically arranged and can move left and right. The two U-shaped frames 2 are located between the two movable seats 6. The base 1 is provided with slide grooves 7 in left and right directions. A slider 8 is fixed to the lower end of each movable seat 6. The slider 8 is placed in the slide groove 7, so that the movable seat 6 can slide left and right along the slide groove 7; a vertical electric telescopic rod 9 is fixed to each movable seat 6, and a mounting plate 10 is fixed to the upper end of the electric telescopic rod 9. A rotating motor 11 is fixed to the mounting plate 10, and a rotating plate 12 is fixed to the output end of the rotating motor 11. The rotating plates 12 on the two rotating motors 11 are opposite to each other. After the material is clamped in the U-shaped frame 2, the movable block moves toward the middle, and the two rotating plates 12 abut against the ends of the two sections of material and clamp them in the middle. The rotating motor 11 rotates, driving the two sections of material to rotate synchronously, and performing 360-degree circumferential welding.

[0017] A screw rod 13 in the left and right directions is passed through the slide groove 7, and the slider 8 cooperates with the screw thread, and the thread rotation direction of the screw rod 13 and the two sliders 8 is opposite. The end of the screw rod 13 is connected to a reciprocating motor 14. The rotation of the reciprocating motor 14 can drive the screw rod 13 to rotate. The screw rod 13 drives the two sliders 8 to move toward or away from each other under the action of the thread, thereby driving the two moving blocks to move toward or away from each other.

[0018] The rotating plate 12 is located between the clamping plate 4 and the rear side wall of the U-shaped frame 2 , so that the material placed inside the U-shaped frame 2 can be clamped.

[0019] A plurality of compression springs 5 ​​are evenly arranged on the surface of the clamping plate 4 , providing a stable and balanced clamping force for the clamping plate 4 .

[0020] When the utility model is in use, the two sections of material to be welded are placed in the two U-shaped frames 2 respectively, and the clamping plate 4 clamps the material under the action of the compression spring 5. Since the two U-shaped frames 2 are in a left-right alignment state, the two sections of material after clamping are also automatically aligned, and then the reciprocating motor 14 is started, and the two moving blocks are driven to move toward the middle through the screw rod 13 until the two rotating plates 12 clamp the ends of the two sections of material, the inner ends of the two sections of material are in contact and pressed, and then welding is started. During the welding process, the two rotating motors 11 rotate synchronously to adjust the position of the material, thereby performing 360-degree circumferential welding; after welding is completed, the two moving blocks move outward, the two rotating plates 12 release the material, and the material can be removed from the U-shaped frame 2.

[0021] The utility model can automatically make the materials placed in the U-shaped frame 2 into a horizontal alignment state through two aligned U-shaped frames 2 and the clamping plate 4, so that the subsequent clamping is more convenient.
