Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a steel structure welding device that ensures welding quality. Background Technology

[0002] Steel structure welding equipment is a core piece of equipment in modern industry for efficiently joining metal components, widely used in construction, bridges, shipbuilding, and heavy machinery manufacturing. This equipment achieves precise welding of steel using electric arc, laser, or resistance heating principles, and features automation and intelligence. Equipped with a CNC system, multi-axis robotic arms, and real-time monitoring sensors, it can perform various processes such as flat welding, vertical welding, and circumferential welding, ensuring both weld strength and aesthetics. The equipment adopts a modular design to adapt to workpieces of different specifications, and combines high efficiency, energy saving, and operational safety, significantly improving steel structure production efficiency and engineering quality, making it one of the key pieces of equipment driving intelligent manufacturing.

[0003] Chinese Patent Publication No. CN221755229U discloses a steel structure welding device, relating to the field of steel structure welding technology. This steel structure welding device includes a base, a welding chamber fixedly connected to the top of the base, a transparent window at the front end of the welding chamber, and an electric welding device located inside the top of the welding chamber. A bidirectional threaded rod is rotatably connected inside the base, and a support plate is slidably connected inside the base, threadedly connected to the bidirectional threaded rod. A rotating clamping mechanism is located on the side of the support plate. This rotating clamping mechanism allows the steel structure tube to pass through a rotating cylinder and a carrier plate, and then be clamped by the clamping plate for welding. A motor can be activated, driving a rotating shaft and gear A to rotate. Gear A rotates a gear ring and a rotating cylinder, thereby rotating the steel structure tube clamped by the clamping plate, thus enabling comprehensive welding of the steel structure tube without the need for re-clamping and fixing, resulting in high welding efficiency.

[0004] The rotating clamping mechanisms in the aforementioned patent documents rotate via a motor and gears, resulting in a lack of synchronous rotation between the two sets of rotating clamping mechanisms. This leads to misalignment during welding of round pipes. Therefore, a steel structure welding device is proposed to ensure welding quality. Utility Model Content

[0005] To address the aforementioned problems, a steel structure welding device is provided to ensure welding quality. A first servo motor drives a splined shaft to rotate, which in turn drives a meshing driven gear to rotate synchronously. Simultaneously, the driven gear drives a meshing toothed belt, which in turn drives a roller to rotate. This ensures that the clamping mechanism can drive the workpiece to rotate synchronously during welding, solving the problem of welding misalignment caused by the workpiece not rotating synchronously.

[0006] To address the problems of the prior art, this application provides a steel structure welding device to ensure welding quality, including a worktable, a clamping mechanism that can move horizontally on the top of the worktable, an adjustable moving frame that is set on the top of the worktable, and a welding part that is set on the top of the moving frame for welding the workpiece. The clamping mechanism includes a base that can move horizontally, and a driven gear that can mesh with a spline shaft is installed on the bottom of one side of the base.

[0007] The top of the base is equipped with a rotating roller. A toothed belt that can mesh with the driven gear is provided on the outer wall of one end of the roller. An arc-shaped clamping plate for clamping the workpiece is provided inside the roller.

[0008] The clamping mechanism also includes a fixing frame, which is used to limit the movement of the roller.

[0009] As one technical solution of this application, slots are provided on both sides of the base;

[0010] The two sides of the mounting bracket are fixed with inserts that can be inserted into the slots.

[0011] As one technical solution of this application, the base is fixed with a first hydraulic telescopic component on both sides, which can drive the fixed frame to move longitudinally, and the telescopic end of the first hydraulic telescopic component is fixedly connected to the fixed frame.

[0012] As one technical solution of this application, the end of the roller away from the toothed belt is provided with a plurality of threaded holes at equal intervals around its central axis, and a rotatable threaded rod is installed inside the threaded hole, one end of the threaded rod being movably connected to the arc-shaped clamping plate.

[0013] As one technical solution of this application, a limiting hole is provided on the side of the roller near the threaded hole;

[0014] The arc-shaped clamp plate is symmetrically fixed with a limiting rod that can slide with the limiting hole on the side near the threaded rod.

[0015] As one technical solution of this application, a second slide rail is symmetrically fixed on the upper surface of the workbench;

[0016] The bottom of the base is symmetrically provided with second slide grooves that can slide along the second slide rail;

[0017] A second hydraulic telescopic assembly for moving the base is horizontally installed on the lower end face of the workbench near the second slide rail. The telescopic end of the second hydraulic telescopic assembly is fixedly connected to the base.

[0018] As a technical solution of this application, the bottom of the worktable is also provided with a rotatable lead screw, and the central axis of the lead screw is perpendicular to the central axis of the spline shaft on the horizontal projection plane.

[0019] A limiting frame is fixed on one side of the bottom of the movable frame. A threaded sleeve that can be fitted onto the lead screw is horizontally opened on the side of the limiting frame away from the movable frame. The threaded sleeve is threadedly engaged with the lead screw.

[0020] As one technical solution of this application, a first slide rail is fixed at the center of the upper surface of the workbench;

[0021] A horizontal plate is horizontally arranged above the limiting frame on one side of the movable frame, and a first groove is formed on the lower end surface of the horizontal plate to slide with the first slide rail.

[0022] The advantages of this utility model compared to the prior art are:

[0023] This application utilizes a first servo motor to drive a splined shaft to rotate, which in turn drives a meshing driven gear to rotate synchronously. The rotation of the driven gear simultaneously drives a meshing toothed belt, which in turn drives a roller to rotate. This achieves synchronous rotation of the workpiece by the clamping mechanism during welding, solving the problem of welding misalignment caused by the workpiece's inability to rotate synchronously.

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0032] See Figures 1-6 As shown, a steel structure welding device for ensuring welding quality includes a workbench 1, a clamping mechanism 3 that can move horizontally on the top of the workbench 1, an adjustable movable frame 2 that is set on the top of the workbench 1, and a welding part 21 that is set on the top of the movable frame 2 for welding the workpiece. The clamping mechanism 3 includes a base 31 that can move horizontally, and a driven gear 312 that can mesh with a spline shaft 4 is installed on the bottom of one side of the base 31.

[0033] A rotatable roller 34 is mounted on the top of the base 31. A toothed belt 341 that can mesh with the driven gear 312 is provided on the outer wall of one end of the roller 34. An arc-shaped clamping plate 343 for clamping the workpiece is provided inside the roller 34.

[0034] The clamping mechanism 3 also includes a fixing frame 32, which is used to limit the movement of the roller 34.

[0035] A first servo motor 6 for driving the spline shaft 4 to rotate is also fixed on one side of the worktable 1. The output end of the first servo motor 6 can be fixedly connected to one end of the spline shaft 4. When the first servo motor 6 is driven, it will drive the spline shaft 4 to rotate. At this time, the rotation of the spline shaft 4 will drive the driven gear 312 meshing with it to rotate synchronously. The rotation of the driven gear 312 will drive the toothed belt 341 meshing with it, so that the driven gear 312 drives the roller 34 to rotate through the toothed belt 341. This realizes that when the welding device welds the workpiece, the clamping mechanism 3 can drive the workpiece to rotate synchronously, solving the problem of welding misalignment caused by the workpiece not rotating synchronously.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, slots 313 are provided on both sides of the base 31;

[0037] The two sides of the mounting bracket 32 ​​are fixed with insert blocks 321 that can be inserted into the slots 313.

[0038] To ensure the stability of the mounting bracket 32, insert blocks 321 are longitudinally fixed on both sides of the mounting bracket 32. When the mounting bracket 32 ​​moves longitudinally, it causes the insert blocks 321 to slide along the slot 313. This effectively prevents the mounting bracket 32 ​​from shifting during movement, thus ensuring that the mounting bracket 32 ​​can accurately align with the base 31.

[0039] See Figure 3 and Figure 4 As shown, the base 31 has a first hydraulic telescopic component 33 fixed on both sides, which can drive the fixed frame 32 to move longitudinally. The telescopic end of the first hydraulic telescopic component 33 is fixedly connected to the fixed frame 32.

[0040] To limit the movement of the roller 34, a first hydraulic telescopic assembly 33 is fixed to both sides of the base 31. When the first hydraulic telescopic assembly 33 is activated, it drives the fixing frame 32 to move longitudinally. When the fixing frame 32 moves downward, it presses down on the top of the roller 34, thereby allowing the fixing frame 32 and the base 31 to cooperate in limiting the movement of the roller 34.

[0041] See Figure 3 and Figure 4 As shown, the end of the roller 34 away from the toothed belt 341 has several threaded holes 345 equidistantly opened around its central axis. A rotatable threaded rod 342 is installed inside the threaded hole 345, and one end of the threaded rod 342 is movably connected to the arc-shaped clamping plate 343.

[0042] When the threaded rod 342 is rotated, it can move along the central axis of the threaded hole 345. At this time, the threaded rod 342 will drive the arc-shaped clamping plate 343 to move synchronously, thereby enabling the arc-shaped clamping plate 343 to clamp or release the workpiece.

[0043] See Figure 3 and Figure 4 As shown, a limiting hole 346 is provided on the side of the roller 34 near the threaded hole 345;

[0044] A limiting rod 344, which can slide and engage with the limiting hole 346, is symmetrically fixed on the side of the arc-shaped clamping plate 343 near the threaded rod 342.

[0045] To ensure the stability of the arc-shaped clamping plate 343, a limiting rod 344 is provided on the side of the arc-shaped clamping plate 343 near the threaded rod 342. When the arc-shaped clamping plate 343 moves, it can drive the limiting rod 344 to slide along the central axis of the limiting hole 346. This effectively ensures the stability of the arc-shaped clamping plate 343.

[0046] See Figure 1 and Figure 2 As shown, a second horizontally arranged slide rail 12 is symmetrically fixed on the upper surface of the worktable 1;

[0047] The bottom of the base 31 is symmetrically provided with second slide grooves 311 that can slide along the second slide rail 12;

[0048] A second hydraulic telescopic assembly 5 for moving the base 31 is horizontally installed on the lower end face of the workbench 1 near the side of the second slide rail 12. The telescopic end of the second hydraulic telescopic assembly 5 is fixedly connected to the base 31.

[0049] When the second hydraulic telescopic component 5 is activated, it will drive the base 31 through the telescopic end, so that the base 31 can move along the central axis of the second slide rail 12 through the second slide groove 311, effectively preventing the base 31 from shifting during movement, thereby ensuring the stability of the base 31.

[0050] See Figure 1 , Figure 5 and Figure 6 As shown, the bottom of the worktable 1 is also equipped with a rotatable lead screw 71, and the central axis of the lead screw 71 is perpendicular to the central axis of the spline shaft 4 on the horizontal projection plane.

[0051] A limiting frame 22 is fixed on one side of the bottom of the movable frame 2. A threaded sleeve 23 that can be fitted onto the lead screw 71 is horizontally opened on the side of the limiting frame 2 away from the movable frame 2. The threaded sleeve 23 is threadedly engaged with the lead screw 71.

[0052] The worktable 1 is also equipped with a second servo motor 7 for driving the lead screw 71 to rotate. The output end of the second servo motor 7 is fixedly connected to one end of the lead screw 71. When the second servo motor 7 is started, it drives the lead screw 71 at its output end to rotate synchronously. When the lead screw 71 rotates, it can drive the limiting frame 22 through the threaded sleeve 23 that is threaded with it, and then the limiting frame 22 drives the moving frame 2 to move along the Y-axis. This allows the moving frame 2 to drive the welding part 21 on its top to move synchronously to adjust the welding position.

[0053] See Figure 1 , Figure 5 and Figure 6 As shown, a first slide rail 11 is fixed at the center of the upper surface of the workbench 1;

[0054] A horizontal plate 24 is horizontally arranged above the limit frame 22 on one side of the movable frame 2. The lower end surface of the horizontal plate 24 is provided with a first slide groove 25 that can slide and cooperate with the first slide rail 11.

[0055] To ensure the stability of the movable frame 2, a horizontal plate 24 is fixed to one side of the movable frame 2, and a first sliding groove 25 is formed on the lower end face of the limiting frame 22. When the movable frame 2 moves horizontally, it will drive the horizontal plate 24 to move synchronously. When the horizontal plate 24 moves, it will move along the central axis of the first slide rail 11 through the first sliding groove 25. This effectively ensures the stability of the movable frame 2 and prevents it from deviating during movement.

[0056] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
