[0021] By adopting the above solution, the clamping mechanism 3 can be adapted to butterfly valve bodies of different sizes, which is more convenient to use, and the welding gun adjustment mechanism 5 can adjust the position of the welding gun 54 to ensure the quality of welding.

[0022] The flip mechanism 2 includes a first gear 21 rotatably connected to one end of the side of the support base 1 , a second gear 22 is provided at one end above the first gear 21 , and a flip plate 23 is fixedly connected to one end of the side of the second gear 22 .

[0023] The above scheme is adopted: the first gear 21 is driven to rotate by the flip motor 6, thereby driving the second gear 22 meshing at the upper end to rotate, thereby driving the flip plate 23 fixed on the side to rotate, thereby driving the clamping mechanism 3 fixed on the side of the flip plate 23 to flip.

[0024] The clamping mechanism 3 includes a connecting plate 31 fixedly connected to one end of the side of the flipping mechanism 2, a stepping motor 32 is arranged at one end of the side of the connecting plate 31, a rotating rod 33 is fixedly connected to the output end of the side of the stepping motor 32, a first bevel gear 34 is fixedly connected to one end of the side of the rotating rod 33, a second bevel gear 35 is arranged at the lower end of the first bevel gear 34, a bidirectional screw rod 36 is fixedly connected to one end below the second bevel gear 35, and the thread directions on both sides of the surface are arranged in opposite directions, an upper supporting block 37 is screwed to one end of the side of the bidirectional screw rod 36, and a lower supporting block 38 is screwed to one end of the side of the bidirectional screw rod 36.

[0025] The above scheme is adopted: the stepper motor 32 drives the rotating rod 33 to rotate, thereby driving the first bevel gear 34 fixed on the side to rotate, driving the second bevel gear 35 meshing below to rotate, and the two-way screw rod 36 fixed below the second bevel gear 35 drives the upper supporting block 37 and the lower supporting block 38 screwed on the side to move relative to each other, thereby clamping the butterfly valve body.

The rotating seat 53 can fine-tune the angle of the welding gun 54, which is more convenient to use. After adjusting the angle position of the welding gun 54, the first gear 21 is driven to rotate by the flipping motor 6, thereby driving the second gear 22 engaged at the upper end to rotate, thereby driving the flip disk 23 fixed on the side to rotate, thereby driving the clamping mechanism 3 fixed on the side of the flip disk 23 to flip, and the rotating shaft inside the supporting mechanism 4 will also rotate with the flipping, thereby avoiding wear of the butterfly valve body due to flipping.
