[0022] The specific operation is as follows: the forward and reverse motor 6 drives the driving shaft 7 and the gear 8 to rotate, and the gear 8 drives the toothed disc 9 to transmit, so that the sliding pin 10 in the slide groove on the surface of the toothed disc 9 drives the moving shell 11 to move linearly in the guide seat 12 toward the direction close to the central axis of the toothed disc 9, and the equal-diameter tee is clamped by the clamping rollers 16 in six directions to ensure the stability of the clamping.

[0023] like Figure 1As shown, an adjustment component 5 is installed at the front end of the left side of the base 1, and the adjustment component 5 includes a servo motor 501 and a positive and negative threaded screw 502. The output end of the servo motor 501 passes through the left side of the base 1 and is connected with the positive and negative threaded screw 502. The adjustment component 5 also includes a screw nut 1 503 and a screw nut 2 504, and the outside of the positive and negative threaded screw 502 is connected with a screw nut 1 503 and a screw nut 2 504.

[0024] The specific operation is as follows: the servo motor 501 drives the forward and reverse screws 502 to rotate, so that the screw nut 1 503 and the screw nut 2 504 respectively drive the sliding seat 1 3 and the sliding seat 2 4 to move horizontally toward or away from each other along the outside of the forward and reverse screws 502 to adapt to equal-diameter tees of different specifications, with the advantages of simple structure and easy adjustment.

[0025] In summary, when the clamping device for welding equal-diameter tees is used, first, the sliding seat 1 3 and the sliding seat 2 4 are slidably connected with the sliding rod 2, and the equal-diameter tee is placed between the sliding seat 1 3 and the sliding seat 2 4 in an inverted T shape, and then the servo motor 501 is controlled to drive the positive and negative threaded screws 502 to rotate, and the sliding seat 1 3 and the sliding seat 2 4 are driven by the screw nut 1 503 and the screw nut 2 504 to move horizontally toward each other along the outside of the positive and negative threaded screws 502, so that the left and right branches of the equal-diameter tee pass through the holes on the surfaces of the sliding seat 1 3 and the sliding seat 2 4 respectively;
