[0040] 1. The present invention can cut and process two steel structures to be processed that need to be butt-jointed by setting a cutting assembly and a welding mechanism, so that the cross-sections of the two steel structures to be processed are adapted, and based on the movement of the toggle mechanism, the two clamping mechanisms are toggled toward each other to make the end faces of the two cut steel structures to be processed fit together, and then welding is performed based on the welding mechanism; since structures such as an annular rotating seat are provided, the angle of the steel structure to be processed can be adjusted according to demand based on the rotation of the annular rotating seat, thereby changing the cutting and welding angles and improving flexibility.

[0041] 2. The present invention is equipped with a clamping mechanism, which can work based on the clamping drive motor, drive the clamping screw to rotate, and make the two clamping frames move toward each other. The two clamping plates clamp the steel structure to be processed. The clamping force causes the elastic rubber plate to deform.

[0043] 4. The present invention sets a toggle mechanism, which can first cut the steel structure to be processed based on the cutting assembly when the electric-controlled translation block moves. As the electric-controlled translation block continues to move, the push frame pushes the slide seat to move. With the deformation of the guide rod spring, the oblique toggle frame pushes the dial wheel, thereby making the clamping mechanisms on both sides move toward each other. Due to the symmetry about the rotation center of the annular rotating seat, the steel structure to be processed can be docked at the center; as the electric-controlled translation block continues to move, the steel structure to be processed is docked in place, and the push frame spring deforms to prevent the structure from getting stuck; at the same time, the welding mechanism moves into place to perform welding operations.

[0077] In order to facilitate the synchronous movement of the clamping mechanism; Figure 3 As shown, the toggle mechanism includes:

[0078] A stand 21, the stand 21 is fixed on the annular rotating seat 3, and the inner wall of the stand 21 is slidably connected with a guide rod 18;

[0079] The oblique shifting frame 8 is fixed to one end of the guide rod 18, and the oblique shifting frame 8 and the vertical frame 21 are connected through the guide rod spring 19. A thumbwheel 45 is installed on the slider 42, and one end of the oblique shifting frame 8 extends to a side of the thumbwheel 45 away from the arc-shaped gear frame 10;

[0080] The connecting rod 48 and the two oblique shifting frames 8 are symmetrically arranged, and the two oblique shifting frames 8 are connected by the connecting rod 48;

As the electric-controlled translation block 7 continues to move, the push frame 23 pushes the slide seat 15 to move, and under the deformation cooperation of the guide rod spring 19, the oblique toggle frame 8 pushes the dial wheel 45, thereby making the clamping mechanisms on both sides move toward each other. Due to the symmetry about the rotation center of the annular rotating seat 3, the steel structure 2 to be processed can be docked at the center; as the electric-controlled translation block 7 continues to move, since the steel structure 2 to be processed is docked in place, the push frame spring 20 is deformed to prevent the structure from getting stuck; at the same time, the welding mechanism moves into place to perform welding operations;

[0088] Among them, the stiffness coefficient of each spring should be set according to the actual situation. For example, the guide rod spring 19 should be easier to deform than the push frame spring 20, so as to ensure the smooth docking.
