[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1 to Figure 4 In an embodiment of the utility model, an auxiliary docking device for steel structure processing includes a placement table 1 for supporting the steel structure, a driving mechanism is installed at the bottom end of the placement table 1, and the driving mechanism is used to drive a clamping mechanism to align and clamp the steel structure; the clamping mechanism includes a clamping plate 7, and a limiting mechanism extending to the outside of the clamping plate 7 is arranged inside the clamping plate 7; the limiting mechanism in the unclamped state cooperates with the clamping mechanism to splice the butt ends of two steel structures; the limiting mechanism in the clamped state is used to limit the movement of the steel structure in the axial direction.
[0021] In this embodiment: when welding two square steel structures of the same specification, first grind a groove on the butt end of the two steel structures to facilitate welding, then place the steel structures on the placement table 1, and make the grooves of the two steel structures face each other, then start the driving mechanism, and the operation of the driving mechanism drives the clamping mechanism to clamp one side of the two steel structures synchronously, and the clamping mechanism has the function of straightening and aligning the steel structures during the clamping process.
[0022] After the clamping mechanism is fully clamped, any one steel structure is pushed toward the other steel structure until the grooves of the two steel structures touch each other. At this time, the limiting mechanism is activated to further limit the steel structure to prevent the steel structure from circumferentially moving along the length direction of the placement table 1 during welding, and then the welding operation can be carried out.
[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The driving mechanism includes a worm 12 connected to the outer side of the placement table 1 through a mounting frame, both ends of the worm 12 are rotatably connected to the mounting frame, a forward and reverse motor 11 is installed at the bottom end of the mounting frame, and the output end of the forward and reverse motor 11 is connected to the bottom center of the worm 12; a worm wheel 13 is meshed on the outer periphery of the worm 12, and one end of the worm wheel 13 is connected to a bidirectional screw 14, the bidirectional screw 14 is located in the inner cavity of the guide rail 2, and the bidirectional screw 14 is rotatably connected to the guide rail 2, and the guide rail 2 is fixedly installed at the bottom end of the placement table 1.
[0024] In this embodiment: by starting the forward and reverse motor 11, the forward and reverse motor 11 runs to drive the worm 12 to rotate, the rotating worm 12 drives the worm wheel 13 to rotate, and the rotating worm wheel 13 drives the bidirectional screw 14 to rotate inside the guide rail 2.
[0025] The clamping mechanism can be controlled to clamp or release the steel structure by controlling the rotation direction of the forward and reverse motor 11.
[0026] Please refer to Figure 1 , Figure 2 and Figure 3 The clamping mechanism is symmetrically slidably connected to the two sliding bars 3 in the inner cavity of the guide rail 2. The two sliding bars 3 are symmetrically arranged, and the two sliding bars 3 are threadedly connected to the bidirectional screw 14 through a positive thread and a reverse thread respectively. The sliding bar 3 is connected to a moving rod 4 through a connecting frame. The moving rod 4 is located above the placement table 1 and is vertically arranged. The moving rod 4 drives a cross bar 5 welded on the inside; a No. 1 V-shaped plate 6 is fixedly connected to the inner side of the cross bar 5, and a clamping plate 7 is integrally formed at both ends of the No. 1 V-shaped plate 6.
[0027] In this embodiment: when the worm wheel 13 rotates, the worm wheel 13 drives the bidirectional screw 14 to rotate, and at this time, the tops of the two slide bars 3 move toward or away from each other under the action of their internal threads. The movement toward each other clamps the steel structure, and the movement away from each other releases the clamping of the steel structure.
[0028] During clamping, the sliding rod 3 drives the moving rod 4 to move through the connecting frame, and the two moving rods 4 drive the cross rod 5 to move respectively, and the cross rod 5 drives the No. 1 V-shaped plate 6 to move. The No. 1 V-shaped plate 6 drives two clamping plates 7 to clamp the steel structure. The clamping plates 7 have the function of straightening and aligning the two steel structures during the clamping process.
[0029] Please refer to Figure 1 and Figure 4 An electric push cylinder 8 is installed at the top of the limiting mechanism, and the output end of the electric push cylinder 8 is connected to a second V-shaped plate 9. Both ends of the second V-shaped plate 9 are formed with downwardly extending fixed rods, and the bottom end of the fixed rod is connected to a movable plate 10. A plurality of pressure plates 17 are equidistantly formed on one end surface of the movable plate 10 close to the clamping plate 7.
[0030] In this embodiment: after the steel structure is clamped, by pushing any one of the steel structures toward the other steel structure, or pushing the two steel structures toward each other, until the grooves of the two steel structures touch, the electric push cylinder 8 is started, and the telescopic part of the electric push cylinder 8 extends to drive the second V-shaped plate 9 to move, and the second V-shaped plate 9 drives the moving plate 10 to move through the fixed rod, and the moving plate 10 drives the pressing plate 17 to press the surface of the steel structure, so as to limit the steel structure again and avoid axial movement of the steel structure during the welding process.
[0031] It should be noted that: due to the presence of the No. 1 V-shaped plate 6 and the No. 2 V-shaped plate 9, the three surfaces can be quickly welded, and the last surface can be welded by turning over the steel structure after the three surfaces are welded.
[0032] Please refer to Figure 4 A guide groove 16 for the pressure plate 17 to move is provided inside the clamping plate 7 , and the inner wall of the guide groove 16 coincides with the outer wall of the pressure plate 17 .
[0033] In this embodiment, when the movable plate 10 moves, the movable plate 10 drives the pressing plate 17 to move along the guide groove 16 , and the guide groove 16 provides a movement guide for the pressing plate 17 .
[0034] Please refer to Figure 4 A plurality of rollers 15 are equidistantly rotatably connected inside the clamping plate 7 , and the guide grooves 16 and the rollers 15 are alternately arranged.
[0035] In this embodiment, when the pressing plate 17 does not clamp the steel structure, the steel structure is pushed, and due to the existence of the rollers 15, the steel structure can slide easily.
[0036] Please refer to Figure 3 The slide bar 3 is located at the top of the inner cavity of the guide rail 2 and has an inverted "convex" structure with the vertical section of the guide rail 2.
[0037] In this embodiment, the sliding rod 3 can be prevented from being separated from the guide rail 2.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
