[0017] The working principle of the present application is: In use, the clamping mechanism plays a key role in fixing and arranging the steel frame to assist welding production. For the top clamping assembly 1, the worker first places the four steel pipes forming the upper plane steel frame on the sliding table 2. Since the sliding table 2 has a landslide design, the steel pipes will slide down the sliding table 2 to the upper surface of the clamping table 3. At this time, the worker starts the drive motor 4 through a signal, and the output end on the upper surface of the drive motor 4 drives the meshing screw 5 to rotate. Based on the meshing effect of the meshing screw 5 and the meshing frame body 6, the meshing frame body 6 starts to rise, thereby synchronously rising the steel pipes. Finally, the upper end of the fixed plate body 7 cooperates with the small transmission belt 8 to clamp the center of the steel pipe, and the four steel pipes are thus combined into a plane steel frame state. If the positions of the steel pipes are not aligned, the worker can drive the small transmission belt 8 to start, thereby moving the steel pipes to one side for adjustment until the positions are accurate. Moreover, the worker can drive the two small motors 9 to start according to the size of the required production steel frame, so that the four sliding tables 2 move inward or outward synchronously, thereby meeting the demand of combining steel pipes of different lengths into plane steel frames of different sizes. After the positions of the four steel pipes of the upper plane steel frame are fixed, the four bottom clamping assemblies 11 come to the upper surface of the clamping table 3 as the meshing frame body 6 rises. The worker then places the four steel pipes forming the lower plane steel frame above the clamping table 3. By driving the electric rotating shaft 13 on both sides of the lifting block body 12 through a signal, the two rotatable clamping plates 14 clamp the center of the steel pipes forming the lower plane steel frame, so that they form the same splicing state as the upper plane steel frame. Subsequently, the rotating shield plate 15 rotates under the drive of the electric turntable 16, thereby shielding the welding points between the upper plane steel frame and the lower plane steel frame, effectively avoiding interference between the two sides when welding at the same time. Then, the worker can use the welding equipment to weld the connection between the pre-spliced upper and lower plane steel frames, so that the steel pipes are fixed and a fixed plane structure is formed. After welding is completed, the rotating shield plate 15 is retracted to the original position. The vertical clamping assembly 17 is used to place and pre-fix the vertical steel pipes to create a good welding environment. After the worker fixes the vertical steel pipes through the electric clamping jaw 18, the upper plane steel frame and the lower plane steel frame are welded. By driving the electric telescopic rod 19 to extend through a signal, the electric telescopic rod 19 drives the bottom fixed plate 20. The bottom fixed plate 20 and the upper fixed plate 21 move stably due to the cooperation of the limiting block 22 and the bottom seat side surface limiting groove 23. At the same time, the servo motor 24 drives the internal screw 25 to rotate, so that the vertical steel pipes clamped by the electric clamping jaw 18 move with the movable stand 26, and are precisely spliced with the upper and lower plane steel frames. Subsequently, welding work is performed, and finally the two plane steel frames are connected to become a finished three-dimensional steel frame.
