Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing technology, and in particular to a steel structure welding device. Background Technology

[0002] Steel structures are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. The components or parts are usually connected by welds, bolts, or rivets. Some steel structures require a certain angle to be formed during welding. Nowadays, most welding equipment uses fixing components to fix the steel structure in order to improve the stability of welding. However, the angle of most fixing components cannot be adjusted, making it difficult to adjust the welding angle of the steel structure, thereby reducing the efficiency of steel structure welding.

[0003] A Chinese patent (authorization announcement number CN218575373U) discloses a steel structure welding device, which includes: "a base plate, an operating table slidably connected to the top of the base plate, a support frame fixedly installed on the top of the base plate, and a welding rod fixedly provided on one side of the support frame; the operating table is provided with an adjusting clamping mechanism, and the adjusting clamping mechanism includes a groove, a sliding plate, a clamping plate, a support column, a movable plate, a rotating shaft, a connecting plate, and a rotating rod."

[0004] It is evident that the cited patent document suffers from the problem of difficulty in adjusting the welding angle of the steel structure. Utility Model Content

[0005] The purpose of this invention is to provide a steel structure welding device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure welding device, including a welding base, a groove on the top surface of the welding base, an electric push rod installed on one side of the welding base, the output end of the electric push rod penetrating into the groove and connected to a rack with teeth on both sides, two rotating shafts rotatably connected to the inner bottom surface of the groove, the rack being located between the two rotating shafts, gears meshing with the rack being fixedly sleeved on the periphery of each of the two rotating shafts, a rotating seat connected to the top of each of the two rotating shafts, a placement seat for placing the steel structure being installed on the top surface of each of the two rotating seats, and a fixing component for clamping the steel structure being provided on the top surface of each of the two placement seats.

[0007] Preferably, the fixing assembly includes two slots, two bidirectional threaded rods, four moving blocks, and four clamping blocks.

[0008] Preferably, the two slots are respectively opened on the top surface of the two placement seats, and the two bidirectional threaded rods are respectively rotatably connected to the inner sidewalls of the two slots through pins.

[0009] Preferably, the four movable blocks are respectively threaded onto the periphery of the two bidirectional threaded rods, and the four clamping blocks are respectively connected and fixed to the top surface of the four movable blocks.

[0010] Preferably, a top plate is fixedly mounted on one side of the welding base via a bracket, and a cylinder is mounted on one side of the top plate. The piston rod of the cylinder passes through the top plate and is connected to a movable block.

[0011] Preferably, a hydraulic rod is connected to the bottom surface of the movable block, a mounting bracket is connected to the piston end of the hydraulic rod, and a motor is mounted on one side of the mounting bracket.

[0012] Preferably, the output end of the motor is connected to a rotating rod through the mounting bracket, a rotating block is fixedly sleeved on the periphery of the rotating rod, and a welding gun is connected to the bottom surface of the rotating block.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This steel structure welding device, by activating an electric push rod, enables the rack to move, thereby allowing the two rotating shafts to rotate in both directions. This allows the two placement seats to also rotate in both directions, adjusting the angle between the two placement seats according to the required angle of the steel structure to be welded. Compared to existing devices for welding steel structures, this device can be adjusted according to the required angle of the steel structure, making it easier for personnel to weld steel structures that need to form a certain angle, saving both time and effort.

[0015] The fixing components allow the steel structure placed on top of the mounting base to be clamped, facilitating subsequent welding.

[0016] By turning on the motor, the rotating rod can be rotated, which in turn drives the rotating block and welding torch to rotate around the rotating rod as the axis, allowing the welding torch to be adjusted to different welding angles, thus enabling welding to be performed on areas that require a certain angle.

Detailed Implementation

[0025] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0028] like Figures 1 to 5 The steel structure welding device shown includes a welding base 1, a groove 2 on the top surface of the welding base 1, an electric push rod 3 mounted on one side of the welding base 1, the output end of the electric push rod 3 passing through the groove 2 and connected to a rack 4 with teeth on both sides, and two rotating shafts 5 rotatably connected to the inner bottom surface of the groove 2, with the rack 4 located between the two rotating shafts 5, and gears 6 fixedly fitted around the periphery of each of the two rotating shafts 5 to mesh with the rack 4. By activating the electric push rod 3, the rack 4 can be driven to reciprocate. Since the rack 4 has teeth on both sides and the two gears 6 mesh with the rack 4 respectively, when the rack 4 moves, it will drive the two gears 6 to rotate clockwise and counterclockwise respectively, thereby driving the two rotating shafts 5 to rotate clockwise and counterclockwise respectively.

[0029] The top ends of the two rotating shafts 5 are connected to rotating seats 7, and the top surfaces of the two rotating seats 7 are equipped with placement seats 8 for placing steel structures. When the two rotating shafts 5 rotate clockwise and counterclockwise respectively, they will drive the rotating seats 7 to rotate clockwise and counterclockwise respectively, which in turn will drive the placement seats 8 to rotate clockwise and counterclockwise respectively, so that the angle between the two placement seats 8 matches the included angle of the steel structure to be welded.

[0030] The top surfaces of both placement seats 8 are provided with fixing components for clamping the steel structure. The fixing components include two slots 9, two double-threaded rods 10, four moving blocks 11, and four clamping blocks 12. The two slots 9 are respectively opened on the top surfaces of the two placement seats 8. The two double-threaded rods 10 are rotatably connected to the inner walls of the two slots 9 via pins. One end of each double-threaded rod 10 passes through the placement seat 8 and is connected to a knob. The four moving blocks 11 are threaded onto the periphery of the two double-threaded rods 10, and the four clamping blocks 12 are respectively connected to the four moving blocks 11. After the top surface of the two placement seats 8 is fixed, the required steel structure is placed on the top surface of the two placement seats 8, and the ends of the two steel structures to be welded are brought together. Then, the knob is turned, which drives the bidirectional threaded rod 10 to rotate, thereby driving the two moving blocks 11 to move in opposite directions, which in turn drives the two clamping blocks 12 to move in opposite directions, thereby clamping and fixing the steel structure, and then the steel structure can be welded. This avoids the difficulty in adjusting the welding angle of the steel structure and improves the efficiency of steel structure welding.

[0031] A top plate 13 is fixedly installed on one side of the welding base 1 via a bracket. A cylinder 14 is installed on one side of the top plate 13. The piston rod of the cylinder 14 passes through the top plate 13 and is connected to a movable block 15. By opening the cylinder 14, the movable block 15 can be moved. A horizontal plate is installed on the inner side wall of the top plate 13. The movable block 15 is slidably sleeved on the periphery of the horizontal plate, so that the movable block 15 moves around the periphery of the horizontal plate when it moves, thereby improving the stability of the movable block 15 when it moves.

[0032] A hydraulic rod 16 is connected to the bottom surface of the movable block 15. A mounting bracket 17 is connected to the piston end of the hydraulic rod 16. A motor 18 is mounted on one side of the mounting bracket 17. The output end of the motor 18 passes through the mounting bracket 17 and is connected to a rotating rod 19. A rotating block 20 is fixedly sleeved on the periphery of the rotating rod 19. A welding torch 21 is connected to the bottom surface of the rotating block 20. When the movable block 15 moves, it will drive the hydraulic rod 16, the mounting bracket 17, the rotating rod 19, the rotating block 20, and the welding torch 21 to move, allowing the welding torch 21 to move to the required welding position. Then, the hydraulic rod 16 is turned on, which will drive the welding torch 21 to move downward for welding. By turning on the motor 18, the rotating rod 19 will be rotated, thereby causing the rotating block 20 and the welding torch 21 to make circular motion around the rotating rod 19 as the axis, adjusting the angle of the welding torch 21 so that the welding torch 21 can weld at the required angle.

[0033] Working principle:

[0034] This steel structure welding device, by activating the electric push rod 3, moves the rack 4. Since the rack 4 has teeth on both sides and two gears 6 mesh with it, the movement of the rack 4 causes the two gears 6 to rotate clockwise and counterclockwise respectively. This, in turn, causes the two rotating shafts 5 to rotate clockwise and counterclockwise respectively. This, in turn, causes the placement seats 8 to rotate via the rotating seat 7, aligning the angle between the two placement seats 8 with the angle of the steel structure to be welded. The steel structure is then placed on the top surface of the two placement seats 8, with the ends to be welded abutting each other. Turning the knob causes the two moving blocks 11 to move in opposite directions via the bidirectional threaded rod 10, which in turn causes the two clamping blocks 12 to move in opposite directions, clamping and fixing the steel structure for welding. This avoids the difficulty of adjusting the welding angle of the steel structure and improves the efficiency of steel structure welding.
