Description

Technical Field

[0001] This disclosure relates to the field of steel structure welding technology, and in particular to an intelligent welding equipment for steel structures used in building engineering. Background Technology

[0002] With the continuous development of construction engineering technology, high-rise buildings are becoming increasingly common. In order to reduce the overall weight of high-rise buildings, a large amount of steel structure is used to form a supporting frame, such as H-beams and I-beams. In order to improve the construction speed, the steel structure generally needs to be pre-welded and then assembled on site. However, in the actual use of steel structure welding, there are still some drawbacks. For example, when welding different steel components, such as angle steel, box beams, and connecting ends, it is not possible to ensure that the welding surfaces are in tight and fixed contact, which is not conducive to maintaining the welding at the connection and affects the welding quality.

[0003] According to a patent document with publication number CN121199477A, ​​a steel structure welding device for building engineering includes a frame. The top surface of the frame is provided with a first roller and a third roller for assisting in pushing steel plates. A welding torch is located in the middle of the frame. The device also includes a second roller, which is scissorably positioned above the first roller. Sliding sleeves are mounted on the outer sides of the first, second, and third rollers. A fixed frame is slidably connected between the first and third rollers. A liftable mounting frame is provided on the inner side of the fixed frame, and a drive wheel for pushing the steel plates is rotatably mounted on the inner side of the mounting frame. Anti-slip cushioning is affixed to the outer side of the drive wheel. The padding technology utilizes the lifting of the second roller to facilitate downward pressure and limiting of the steel structure, and the support of the first and third rollers ensures stable transport of the steel structure. Simultaneously, sliding sleeves are slidably installed on the outer sides of the first, second, and third rollers. Adjusting the position of these sleeves allows for targeted transport of different steel structures through contact with different points on the steel structure. While this technology achieves stable transport of the steel structure, it cannot simultaneously compress the material inwards, thus failing to reduce gaps at connection points. Furthermore, it cannot provide multi-point support and rapid cooling of the weld points during steel structure welding, resulting in inconvenience in use. Summary of the Invention

[0008] Optionally, a lifting mechanism is fixedly installed on the limiting seat, a telescopic column is installed on the lifting mechanism, a pressing seat is fixed at one end of the telescopic column, the pressing seat is pressed and installed on the top of the workpiece, and a support frame is fixedly installed on the side of the fixed seat.

[0009] Optionally, a heat sink is fixed to one side of the positioning plate, and a support tube is fixed to the other side of the positioning plate. A limit plate is welded onto the support tube. An installation groove is opened at the bottom of the clamping rod, and a movable rod is movably installed inside the installation groove. A friction block is fixedly installed at one end of both the movable rod and the clamping rod.

[0010] Optionally, a sliding groove is formed on the inner wall of the mounting groove, and a tension mechanism and a limiting block are fixed inside the sliding groove. A slider is fixed at one end of the tension mechanism, and the slider is movably installed inside the sliding groove. A limiting groove is formed on the side of the slider, and the limiting block is movably installed inside the limiting groove.

[0011] Optionally, a fixing block is welded to the inner wall of the fixing groove, a connecting groove is opened at the bottom of the mounting base, the mounting base is movably mounted on the fixing block through the connecting groove, and a fixing bolt is rotatably installed between the fixing block and the mounting base.

[0012] Optionally, the fixing component includes a fixing post, one end of which is fixed to the top of the mounting base. A fixing tube is movably mounted on the fixing post and fixed to the clamping rod. A torsion spring is fixedly installed between the fixing tube and the fixing post.

[0013] Optionally, a cooling fan is fixedly installed inside the heat sink, and the cooling fan is fixedly installed at one end of the support tube. An opening is opened on the side of the movable seat, and a roller is rotatably installed inside the opening.

[0014] Optionally, the support frame has a sliding groove, and a displacement mechanism is fixedly installed inside the sliding groove. One end of the displacement mechanism is fixedly attached to a motor base, and a welding head is fixedly installed on the motor base.

[0015] Optionally, a threaded post is mounted on the drive motor, and the threaded post is rotatably mounted on a threaded seat.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: In this invention, the positioning plate moves to open the limiting rod to both sides parallel to the positioning plate. Initially, the steel structure clamps and fixes one end of the rear support tube at the connection point. The limiting component then compresses and fixes the other two points. After the workpiece is fixed, the support tube moves and separates from the welding point. This separation avoids damage to one end of the support tube caused by the high temperature generated during welding. When the support tube retracts and moves, one end of the clamping plate loses the support of the positioning plate. The clamping rod contacts the workpiece from the outside to the inside. The clamping rod pushes the workpiece inward while providing multi-point limiting support, thereby ensuring the stability of the workpiece during welding. In this invention, when the clamping rod tilts and rotates, the movable rod contacts the bottom of the workpiece. The workpiece pushes the movable rod to move inside the mounting groove. After the movable rod moves, it is vertically misaligned with the clamping rod. The limiting rod after the vertical misalignment achieves vertical and vertical limitation of the workpiece. When the support tube moves, it pushes one end of the clamping rod to move and tilt through the limiting plate. The movement of the limiting plate provides support and clamping for the clamping rod. In addition, after the support tube moves, it creates a distance from the welding point. Later, the airflow blown by the cooling fan blows to the welding point through one end of the support tube to quickly cool the welding point. In this invention, when the extrusion seat clamps the workpiece from above and below, the limiting seat moves horizontally on the fixed frame. The movement of the limiting seat adjusts the position of the extrusion point. While the extrusion seat clamps the workpiece, the support mechanism drives the limiting seat to move inward continuously. While the extrusion seat is pressing and fixing, the horizontal movement force of the limiting seat causes the extrusion seat to push the workpiece to move inward continuously, thereby reducing the gap at the welding point. The workpiece is movably mounted on the movable seat, which provides auxiliary force for the workpiece to move inward later. In addition, when the workpiece is short, the fixed frame can be rotated 90 degrees, and the extrusion seat can clamp and fix the workpiece from both ends, meeting the welding needs under different conditions.

[0020] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] like Figures 1 to 8As shown, an intelligent welding equipment for steel structures in construction engineering includes: a fixed base 1, on which a fixed groove 2 is formed, and a positioning component 3 is movably installed inside the fixed groove 2; movable seats 4 are movably installed at both ends of the fixed base 1, and a workpiece 5 is movably installed on the top of the movable seats 4; a limit component 6 is fixed on the fixed base 1, and the limit component 6 movably cooperates with the workpiece 5; and a positioning component 3, which includes a mounting base 11, on which a drive motor 12 is fixedly installed at one end, and the top of the mounting base 11 is open... A slot 15 is provided, and a threaded seat 16 is movably installed inside the slot 15. A positioning plate 17 is welded to the top of the threaded seat 16, and a clamping rod 18 is movably installed on the side of the positioning plate 17. The clamping rod 18 is mounted on the mounting base 11 via a fixing assembly 19. A limiting assembly 6 is provided, which includes a support plate 36. A fixing frame 37 is movably installed on the support plate 36. The fixing frame 37 is rotatably mounted on the support plate 36 via a fixing shaft 38. A limiting bolt 39 is movably installed between the support plate 36 and the fixing frame 37. A limiting seat 40 is movably installed between the frames 37. After the fixed frame 37 is mounted on the support plate 36 via the fixed shaft 38, the limiting bolt 39 is later removed. The fixed frame 37 rotates on the support plate 36 via the fixed shaft 38. The rotation of the fixed frame 37 controls the tilt angle of the extrusion seat 44. After the tilt angle of the extrusion seat 44 is adjusted, several limiting holes are arc-shaped on the support plate 36. One end of the limiting bolt 39 is movably installed inside different limiting holes, adjusting the tilt angle of the fixed frame 37. The tilted extrusion seat 44 can extrude workpieces 5 of different shapes. The device is clamped and fixed from top and bottom. During welding, in the field of modern building engineering welding, we have integrated intelligent welding systems and intelligent heat treatment production lines. Relying on the manufacturing technology of metal cutting and welding equipment such as automatic and semi-automatic electric arc and plasma arc welding machines, combined with the high-precision prefabricated metal components produced by the intelligent casting island, we have built a complete intelligent system from component casting, welding processing to heat treatment strengthening. This system can not only ensure the accuracy and strength of welding of building steel structure nodes, but also eliminate welding stress through heat treatment process, which can greatly improve the welding quality and structural reliability of building engineering.

[0022] In this embodiment, the limiting seat 40 has a groove 41 on its side, and a protrusion 45 is movably installed inside the groove 41. One end of the protrusion 45 is welded to the fixing frame 37, and a support mechanism 46 is fixed to one side of the protrusion 45. One end of the support mechanism 46 is fixed to the inner wall of the groove 41. A lifting mechanism 42 is fixedly installed on the limiting seat 40, and a telescopic column 43 is installed on the lifting mechanism 42. One end of the telescopic column 43 is fixed to a pressing seat 44, which is pressed and installed on the top of the workpiece 5. A support frame 7 is fixedly installed on the side of the fixing seat 1. A heat sink 25 is fixed on one side of the positioning plate 17, and a support tube 23 is fixed on the other side of the positioning plate 17. A limit plate 24 is welded on the support tube 23. An installation groove 20 is opened at the bottom of the clamping rod 18. A movable rod 21 is movably installed inside the installation groove 20. Friction blocks 22 are fixedly installed at one end of both the movable rod 21 and the clamping rod 18. The support mechanism 46 is a support spring. After the support spring is compressed, it generates a rebound force. The rebound force generated by the support mechanism 46 drives the moved limit seat 40 to return to its original position. Under tension, the workpiece 5 and the movable seat 4 are indirectly driven to move inward through the extrusion seat 44. When the workpiece 5 moves inward, the gap of the welding point is reduced to the maximum extent. Among them, the lifting mechanism 42 and the displacement mechanism 9 are both linear reciprocating electric push rods. The electric push rods are later connected to an external telescopic switch via wires. The telescopic switch controls the telescopic movement of the lifting mechanism 42 and the displacement mechanism 9. The telescopic movement of the displacement mechanism 9 controls the position of the motor base 10. After the position of the motor base 10 is adjusted, the welding head on it performs linear welding at the welding point. A distance sensor is installed at the welding head. The distance sensor intelligently controls the adjustment of the welding focal length, thereby realizing intelligent automatic welding adjustment of the workpiece 5.

[0023] In this embodiment, a sliding groove 26 is formed on the inner wall of the mounting groove 20. A tension mechanism 28 and a limiting block 27 are fixed inside the sliding groove 26. A slider 29 is fixed to one end of the tension mechanism 28. The slider 29 is movably installed inside the sliding groove 26. A limiting groove 30 is formed on the side of the slider 29. The limiting block 27 is movably installed inside the limiting groove 30. A fixing block 13 is welded to the inner wall of the fixing groove 2. A connecting groove is formed at the bottom of the mounting base 11. The mounting base 11 is movably installed on the fixing block 13 through the connecting groove. A fixing bolt 14 is rotatably installed between the fixing block 13 and the mounting base 11. The fixing assembly 19 includes a fixing post 32, one end of which is fixed to the top of the mounting base 11. A fixing tube 31 is movably mounted on the fixing post 32 and fixed to the clamping rod 18. A torsion spring 33 is fixedly installed between the fixing tube 31 and the fixing post 32. When one end of the clamping rod 18 loses the limiting support of the positioning plate 17, the torsion spring 33 drives the fixing tube 31 and the clamping rod 18 to rotate inward. The clamping rod 18 contacts the workpiece 5 through the friction block 22. The force of the clamping rod 18 tilting from the outside to the inside pushes the workpiece 5 inward again. At the same time, the clamping rod 18... One end of the support tube 23 provides multi-point support for the side of the workpiece 5 to ensure the stability of the workpiece 5 during welding. Later, the support tube 23 drives the limiting plate 24 to squeeze one end of the clamping rod 18. The clamping rod 18 tilts under the pressure of the limiting plate 24. The pushing force of the limiting plate 24 completes the strong clamping of the workpiece 5 by the clamping rod 18. As the support tube 23 moves, it creates a distance from the welding point to avoid damage to one end of the support tube 23 caused by high temperature welding. While the support tube 23 moves to support the clamping rod 18, one end of the support tube 23 blows concentrated air to the welding point to quickly cool the welding point, making it easier to remove the workpiece 5 later.

[0024] In this embodiment, a cooling fan 47 is fixedly installed inside the heat sink 25. The cooling fan 47 is fixedly installed at one end of the support tube 23. An opening is opened on the side of the movable seat 4, and a roller 35 is rotatably installed inside the opening. A sliding groove 8 is opened on the support frame 7, and a displacement mechanism 9 is fixedly installed inside the sliding groove 8. A motor seat 10 is fixedly installed at one end of the displacement mechanism 9, and a welding head is fixedly installed on the motor seat 10. A threaded column 34 is installed on the drive motor 12, and the threaded column 34 is rotatably installed on the threaded seat 16. The cooling fan 47 is distributed at one end of the support tube 23. The cooling fan 47 draws air from the outside to the inside and transmits it to the inside of the support tube 23. The airflow cools the welding point through the support tube 23. After the welding point is cooled, it is easier to flip the workpiece 5 for re-welding. When the workpiece 5 is moved outward later, the movable seat 4 moves the workpiece 5 to avoid damage caused by the bottom of the workpiece 5 rubbing against the top of the fixed seat 1 for a long time.

[0025] Working principle: During use, the movable seat 4 is pulled outwards. The movable seat 4 moves inside the fixed seat 1 via rollers 35. While the rollers 35 provide assisted movement, the fixed seat 1 has a positioning groove inside. The rollers 35 stop moving after moving to one end of the positioning groove, thus effectively preventing the movable seat 4 from falling out of the fixed seat 1 due to excessive pulling force. After the workpiece 5 is placed on the movable seat 4, the top of the movable seat 4 is higher than the fixed seat 1. When the movable seat 4 pushes the workpiece 5 to move, the bottom of the workpiece 5 will not rub against the top of the fixed seat 1, thus avoiding friction damage to the fixed seat 1 caused by prolonged welding and moving of the workpiece 5. When the workpiece 5 moves inwards with the movable seat 4, the welding points are joined together. The drive motor 12 is started to drive the threaded column 34 to rotate. The threaded column 34 pushes the threaded seat 16 to move inwards at the same time. As the threaded seat 16 moves, one end of the positioning plate 17 contacts and pushes one end of the clamping rod 18. The clamping rod 18 rotates on the fixed column 32 under the push. The clamping rod 18 rotates and remains parallel to the positioning plate 17. One end of the support tube 23 contacts the weld seam of one end of the workpiece 5. The center point of the workpiece 5 is positioned by the extrusion of the support tube 23. The support tube 23 completes the initial limiting and fixing. Then the limiting seat 40 moves outward. After the limiting seat 40 moves outward, the position of the clamping point is changed. The appropriate fixing point is adjusted according to the length of the workpiece 5. After the limiting seat 40 moves outward, the lifting mechanism 42 is started by the external telescopic switch to push the telescopic column 43 to move downward. Under the push of the telescopic column 43, the extrusion seat 44 limits the workpiece 5 in the upper and lower positions. After the extrusion seat 44 limits the workpiece 5, the support tube 23 retracts and returns to its position. The limiting seat 40 moves inward under the push of the support mechanism 46. The force of the inward movement causes the extrusion seat 44 to drive the workpiece 5 and the movable seat 4 to move inward continuously, so that one end of the workpiece 5 is aligned and fixed. After the support tube 23 retracts and returns to its original position, the positioning plate 17 loses its restriction on the clamping rod 18. Under the elastic force of the torsion spring 33, one end of the clamping rod 18 moves inward. After the clamping rod 18 moves inward, one end contacts the workpiece 5. When the clamping rod 18 contacts the I-beam structure, the bottom of the I-beam contacts the movable rod 21. At the same time, one end of the bottom of the workpiece 5 pushes the movable rod 21 to move, and one end of the clamping rod 18 enters the middle gap of the I-beam. The clamping rod 18 and the movable rod 21 are vertically misaligned, and the vertical misalignment completes the alignment of the workpiece. The upper and lower limits of part 5 are set, and the movable rod 21 and one end of the clamping rod 18 cooperate to provide multi-point limit for the side of part 5. As the support tube 23 moves outward, the limiting plate 24 pushes one end of the clamping rod 18 from the inside out. After the limiting plate 24 pushes one end of the clamping rod 18, the clamping rod 18 rotates around the fixed column 32. The clamping rod 18 pushes the part 5 inward again to align. During welding, the telescopic movement of the displacement mechanism 9 controls the position of the motor base 10. After the position of the motor base 10 is adjusted, the welding head above it is used for welding. Linear welding is performed at the welding point. A distance sensor is installed at the welding head, and the welding focal length is intelligently adjusted by the distance sensor to achieve intelligent automatic welding adjustment of the workpiece 5. After welding is completed, the cooling fan 47 is activated, blowing air from the outside to the inside. The airflow is blown to the welding point through one end of the support pipe 23 to quickly cool the welding point. When adjusting the tilt angle of the limiting component 6, the limiting bolt 39 is removed later. The fixing frame 37 rotates on the support plate 36 through the fixing shaft 38. After the fixing frame 37 rotates, it controls... The tilt angle of the extrusion seat 44 is adjusted. After the tilt angle of the extrusion seat 44 is adjusted, several limiting holes are opened in the arc shape on the support plate 36. After one end of the limiting bolt 39 is movably installed in different limiting holes, the tilt angle of the fixing frame 37 is adjusted. The extrusion seat 44 in the tilted state can clamp and fix workpieces 5 of different shapes from top to bottom. In addition, when the length of the workpiece 5 is short, the fixing frame 37 can be rotated 90 degrees, and the extrusion seat 44 can clamp and fix the workpiece 5 from both ends of the workpiece 5 to meet the welding use in different situations.
