Description

Technical Field

[0001] The present application relates to the technical field of H-beam production equipment, and in particular to an H-beam side flange plate welding device. Background Art

[0002] H-beams are steel beams with an H-shaped cross-section, commonly used in construction. H-beams are typically produced by welding three steel plates together to form an H-shaped main body, followed by argon arc welding of the joints.

[0003] During the welding assembly of H-beams, a single welding gun is often used to weld the joints of the side flanges of the beams. However, this conventional welding assembly method is inefficient and often requires multiple rotations to adjust the welding position. Utility Model Content

[0004] The purpose of the utility model proposed in this application is to improve the problem of low welding assembly efficiency at the connection of the side flange plates of the H-shaped steel beam. The application provides an H-shaped steel beam side flange plate welding device.

[0007] The conveyor frame is provided with multiple groups, with multiple bottom rollers rotatably connected at the bottom, a first telescopic cylinder provided at the top, a top roller abutting against the top side flange plate of the H-shaped steel beam is installed at the end of the piston rod of the first telescopic cylinder, and a second telescopic cylinder provided on the side wall, a side roller abutting against the middle part of the H-shaped steel beam is installed at the end of the piston rod of the second telescopic cylinder, wherein the side rollers and bottom rollers are driven by motors;

[0008] A top plate mounted on the bottom of a first telescopic cylinder of one of the conveyor frames;

[0009] The connecting rod is rotatably connected to both sides of the top plate. The connecting rod is also rotatably connected to the bottom wall of the conveyor frame, opposite to the upper connecting rod. The other ends of the two connecting rods facing each other are rotatably connected to the same mounting bracket. The rotating axes of the two connecting rods facing each other are opposite to each other. When the top roller abuts the H-shaped steel beam, the mounting bracket is opposite to the middle of the H-shaped steel beam.

[0010] There are two welding guns, both of which are installed on the mounting frame and can be adjusted in position. After the position adjustment, the welding guns can respectively weld the two side flange plate connections on one side of the H-shaped steel beam.

[0011] Optionally, the mounting frame is threadedly connected to an adjusting screw, and the adjusting screw is rotatably connected to a mounting plate toward one end of the H-shaped steel beam. The mounting plate is slidingly connected to the mounting frame, and the upper and lower surfaces of the mounting plate are rotatably connected to frame frames. A tension spring is provided between the frames to bring the two clamping frames closer to each other, and the end of the frame can abut and open against the middle steel plate of the H-shaped steel beam, and the welding gun is installed on the frame.

[0012] Optionally, a fixed frame is rotatably connected to the frame, and the welding gun is fixed on the fixed frame. The rotating shaft of the fixed frame is provided with a torsion spring, and when the welding end of the welding gun rotates toward the end of the frame, it encounters resistance. A "V"-shaped positioning plate is fixed to the end of the fixed frame away from its own rotating axis. When both ends of the positioning plate are in contact with the side flange plate of the H-shaped steel beam, the welding gun reaches the welding position.

[0016] The first telescopic cylinder drives the top roller to abut against the top of the H-beam. At the same time, the top plate rotates through the connecting plate so that the mounting frame is located in the middle of the H-beam middle plate. Then, the adjusting screw is rotated to push the mounting plate out, so that the frame abuts against the middle of the H-beam and opens. Then, the welding gun is moved to the required welding position. During the movement of the H-beam, the connection of the H-beam side flange plate can be welded at the same time, which improves the efficiency of the H-beam side flange plate welding.

[0017] During the opening process of the frame, the positioning plate will abut against the side flange plate of the H-shaped steel beam and drive the fixed frame to rotate, thereby causing the welding gun to rotate to the appropriate angle and be located in the position required for welding, thereby improving the effect of automatic adjustment of the welding gun position and thus improving the welding effect.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-3 This application is described in further detail.

[0023] The embodiment of the present application discloses a welding device for side flange plates of an H-shaped steel beam.

[0024] refer to Figure 1 and Figure 2 The H-beam side flange plate welding device includes a conveyor frame 1, a first telescopic cylinder 2, a second telescopic cylinder 3 and a mounting frame 4. The conveyor frame 1 is provided with multiple groups, and multiple bottom rollers 11 are rotatably connected at the bottom. The H-beam passes through the conveyor frame 1 while keeping the two side flange plates in a horizontal state, wherein the side flange plates at the bottom abut against the upper surface of the bottom roller 11. The first telescopic cylinder 2 is installed on the top of the conveyor frame 1, and the piston rod is set downward and fixedly mounted with multiple top rollers 21. The top rollers 21 are arranged side by side and can abut against the side flange plates at the top of the H-beam. The second telescopic cylinder 3 is installed on the side wall of the conveyor frame 1, and multiple side rollers 31 are mounted on the end of the piston rod. The side rollers 31 can abut against the middle of the H-beam. The side rollers 31 and the bottom rollers 11 are both driven to rotate by a motor.

[0025] A top plate 22 is installed at the bottom of the first telescopic cylinder 2 of one of the conveying frames 1. The bottom of the top plate 22 is rotatably connected to a connecting rod 41 at the position on both sides of the H-shaped steel beam. The connecting rod 41 is also rotatably connected to the inner bottom wall of the conveying frame 1, and its position is opposite to the connecting rod 41 placed on it. The other ends of the two connecting rods 41 opposite each other are rotatably connected to the same mounting frame 4, and the rotation axes of the two connecting rods 41 opposite each other are opposite each other. When the lower surface of the top plate 22 is flush with the upper surface of the H-shaped steel beam, the mounting frame 4 is opposite to the middle of the H-shaped steel beam, and at this time the top roller 21 is in contact with the uppermost side flange plate. The mounting frame 4 is threadedly connected to an adjusting screw 43, and the adjusting screw 43 is rotatably connected to a mounting plate 42 toward one end of the H-shaped steel beam. The mounting plate 42 is slidably connected to the mounting frame 4. A self-adjusting component 5 is provided on the mounting plate 42. The self-adjusting assembly 5 on the mounting plate 42 sliding on the mounting frame 4 is provided with two welding guns 6, and the self-adjusting assembly 5 is used to move the two welding guns 6 to the connection between the upper and lower side flange plates and the middle part of the H-shaped steel beam respectively.

[0026] After placing the steel plate of the H-beam on the corresponding position on the conveyor frame 1, the first telescopic cylinder 2 drives the top roller 21 to move downward, pressing the upper side flange plate downward, and the second telescopic cylinder 3 drives the side roller 31 to move, clamping the middle part of the H-beam, and then temporarily assembling and fixing its position. At this time, the top plate 22 drives the connecting rod 41 to rotate, so that the mounting frame 4 is located in the middle position of the middle of the H-beam. At this time, the adjusting screw 43 is rotated to make the mounting plate 42 slide, and the two welding guns 6 are driven by the self-adjusting component 5 to move to the desired welding position. The H-beam is combined and fixed by the welding gun 6. Subsequently, the H-beam connection is continuously welded during the movement of the H-beam, thereby improving the welding efficiency of the H-beam.

[0027] refer to Figure 2 and Figure 3 The self-adjusting assembly 5 includes a frame 51 and a fixed frame 52. There are two frames 51, which are rotatably connected to the upper and lower surfaces of the mounting plate 42, and the two frames 51 are symmetrically arranged. A tension spring 511 is provided between the two frames 51 to make the two clamping frames approach each other. The ends of the two frames 51 away from their own rotation axes are bent in the direction away from each other. The ends of the frames 51 away from their own rotation axes are rotatably connected to the abutment balls 512, and the abutment balls 512 abut and roll against the H-shaped steel beam. The frame 51 abuts and opens against the middle steel plate of the H-shaped steel beam through the abutment balls 512. The fixed frame 52 is rotatably connected to the frame 51, and the welding gun 6 is fixed on the fixed frame 52. The rotation axis of the fixed frame 52 is provided with a torsion spring, and the welding end of the welding gun 6 encounters resistance when it rotates in the direction close to the end of the frame 51. A V-shaped positioning plate 521 is fixed to one end of the fixing frame 52 away from its own rotation axis. When both ends of the positioning plate 521 abut against the side flange plate of the H-shaped steel beam, the welding gun 6 reaches the welding position. Ball bearings 5211 are rotatably connected to both ends of the positioning plate 521.

[0028] As the adjusting screw 43 drives the mounting plate 42 to move, the abutment bead abuts against the middle of the H-beam and forces the two frames 51 away from each other. The bent configuration of the frames 51 effectively improves the efficiency of the frame 51's opening, and the abutment bead configuration effectively improves the efficiency of the frame 51's opening and moving rods. During the frame 51's opening and movement, the positioning plate 521 abuts against the side flanges via the ball bearings 5211, driving the fixed frame 52 to rotate, causing both ball bearings 5211 of the positioning plate 521 to abut against the side flanges, thereby rotating the welding gun 6 to the appropriate angle and moving the welding gun 6 to the desired welding position. The configuration of the frame 51 and the positioning plate 521 ensures that, regardless of the type of H-beam, the two welding guns 6 on the same side can stably and automatically reach the desired welding position simultaneously, welding the joints of the H-beam together and improving the efficiency of H-beam production.

[0029] The implementation principle of the H-beam side flange plate welding device of the embodiment of the present application is as follows: after the side rollers 31 and the top rollers 21 press and fix the various parts of the H-beam, the top plate 22 also drives the mounting frame 4 to move to the middle position of the H-beam through the connecting rod 41. At this time, the adjusting screw 43 is rotated to make the mounting plate 42 slide, and the frame 51 is opened after contacting the middle part of the H-beam, and after the two balls 5211 of the positioning plate 521 are contacted with the side flange plate, the welding gun 6 is driven to move to the required welding position, so that the two welding points on one side of the H-beam can be welded at the same time, thereby improving the welding production efficiency of the H-beam.

[0030] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
