Description

Technical Field

[0001] This invention belongs to the field of tooling technology, specifically a support tooling for welding steel structures. Background Technology

[0002] Support fixtures for steel structure welding can fix steel components, maintain predetermined angles and positions, ensure welding accuracy, provide support for the structure during welding, prevent deformation or displacement, guarantee weld quality, simplify the positioning and fixing steps of steel components, shorten construction time, prevent steel components from shaking or falling during welding, ensure operational safety, and provide necessary support and positioning when welding complex or difficult-to-operate parts. They are an important tool for ensuring the quality of steel structure welding, improving construction efficiency and safety.

[0003] A Chinese patent with publication number CN218695424U discloses a steel structure welding fixture, including a base. Lifting mechanisms are fixedly installed on both sides of the upper surface of the base. The upper surface of each lifting mechanism is fixedly installed on the bottom surface of the moving mechanism. The position of the welding head along the X-axis and Y-axis can be adjusted by a telescopic cylinder and a threaded motor in the control device, so that the predetermined welding point can be welded precisely. It is more convenient to weld at higher welding points, reducing the limitations in steel structure welding work. The entire device can be pushed and supported for fixation, providing convenience and stability in use, making the welding work more efficient and safer.

[0004] However, existing support fixtures for steel structure welding have certain limitations in actual welding operations. When welding workpieces, the fixtures are often not convenient for grinding and subsequent finishing of the weld area, which limits the surface treatment effect after welding. When grinding is required, other tools or equipment must be used, which increases the complexity and time cost of the operation, reduces construction efficiency, and may also affect the consistency of welding quality and the overall effect.

[0005] Therefore, the present invention provides a support fixture for welding steel structures. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problem of inconvenience in polishing welded joints, this invention proposes a support fixture for steel structure welding.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A support fixture for steel structure welding, comprising a workbench, with a first mounting bracket and a second mounting bracket symmetrically arranged on the top of the workbench. The first mounting bracket is fixedly connected to the top of the workbench, and L-shaped supports are symmetrically connected to the second mounting bracket. A driving mechanism for moving the L-shaped supports is provided inside the workbench. A storage component for collecting waste materials is also provided inside the workbench. Clamping mechanisms are provided on both the first and second mounting brackets. Square slots are symmetrically installed on the workbench. One end of the square groove is fixedly connected to a storage groove. The storage groove contains a strip groove, and an electric push rod is fixedly installed inside the strip groove. A strip frame is also provided inside the strip groove, and the telescopic rod of the electric push rod is fixedly connected to the strip frame. A cleaning component is provided on the strip frame. A polishing belt is arranged around the inside of the strip frame via a drive shaft. A drive motor is provided inside the strip frame, and the output end of the drive motor is connected to the drive shaft supporting the polishing belt. A wind mechanism is provided inside the strip groove, and an adjustment mechanism for adjusting the position of the strip groove is provided inside the square groove.

[0008] By adopting the above scheme, when using the steel structure welding support fixture to fix the steel structure to be welded, the clamping mechanisms on the first and second mounting frames can fix the two workpieces to be welded. Then, the drive mechanism moves to adjust the position of the L-shaped bracket. The movement of the L-shaped bracket can adjust the position of the second mounting frame. When the second mounting frame moves, it pushes the fixed and clamped workpieces to move, thereby making the weld joint of the two workpieces fit tightly together. Then, after the external welding machine is moved to the welding point, the workpieces can be welded. The angle of the workpiece can be adjusted by the drive mechanism, and the welding machine can weld different positions of the workpiece, thus improving the support for steel structure welding. The tooling is flexible, and after adjusting the angle of the welded workpiece, the weld marks can be rotated downwards. The cleaning component can clean the workpiece surface and perform air cooling. At the same time, the electric push rod can be activated to move the strip groove. The movement of the strip groove will drive the grinding belt to move. After the grinding belt moves below the grinding point, the position of the strip frame can be adjusted by controlling the electric push rod, which will then drive the grinding belt to move. The position of the grinding belt is judged manually so that the grinding belt contacts the weld. The drive motor is activated, and through the transmission shaft, the grinding belt moves, thus grinding the welded area of ​​the workpiece, effectively removing weld marks and defects.

The cleaning component includes a diversion channel and spray holes. The diversion channel is symmetrically embedded inside the strip frame, and the spray hole array is arranged on the diversion channel.

[0010] By adopting the above solution, the grinding debris from the grinding belt will fall onto the side plate. The grinding debris will slide off the side plate and fall off. After the air enters the diversion groove, it will flow to the surface of the workpiece through the spray holes, thereby cleaning the workpiece.

The clamping assembly is disposed on the rotating disk.

[0014] By adopting the above solution, the worktable is supported by the support legs. When the clamping mechanism moves, the workpiece is fixed and clamped by the clamping component. The servo motor drives the rotating disk to rotate. The rotating disk rotates smoothly through the cooperation of the annular groove and the limit ring. When the rotating disk rotates, it drives the clamping component to rotate. Thus, when the clamping component rotates, the angle of the clamped workpiece can be adjusted, which facilitates welding at different positions of the workpiece.

[0015] Preferably, the clamping assembly includes a sliding groove, a first threaded rod, a clamping block, a threaded ring, a micro motor, and a guide rod.

The guide rod is fixedly disposed inside the sliding groove and passes through the clamping block.

[0016] By adopting the above scheme, after the workpiece is placed on one side of the clamping block, the micro motor will drive the No. 1 threaded rod to rotate. The rotation of the No. 1 threaded rod will adjust the position of the clamping block through the threaded ring. The symmetrically arranged clamping blocks will move in opposite directions. The guide rod will guide the clamping blocks to move smoothly, and the workpiece can be positioned and clamped by the clamping blocks.

[0017] Preferably, the driving mechanism includes a slide groove, a connecting plate, a guide rod, a threaded hole, a second threaded rod, and a second motor. The slide groove is embedded inside the worktable. The connecting plate is disposed inside the slide groove, and both ends of the connecting plate are fixedly connected to the L-shaped bracket.

[0018] By adopting the above scheme, the operation of motor No. 2 will drive the rotation of threaded rod No. 2. When threaded rod No. 2 rotates, the connecting plate will move through the threaded hole. The guide rod will guide the connecting plate to move smoothly. When the connecting plate moves, it will drive the L-shaped bracket to move, and then the L-shaped bracket will drive the No. 2 mounting bracket to move.

[0019] Preferably, the adjusting mechanism includes a No. 3 motor, a No. 3 threaded rod, a threaded cylinder, a guide block, and a limiting rod. The No. 3 motor is fixedly installed inside the square groove. One end of the No. 3 threaded rod is fixedly connected to the output end of the No. 3 motor.

The guide block is fixedly connected to the threaded cylinder. The limiting rod passes through the guide block and is fixedly connected to the inner wall of the square groove.

[0020] By adopting the above scheme, the operation of motor No. 3 will drive the No. 3 threaded rod to rotate. When the No. 3 threaded rod rotates, it will cause the threaded cylinder to move. The movement of the threaded cylinder will cause the guide block to slide on the limit rod. In turn, through the cooperation of the guide block and the limit rod, the threaded cylinder will be guided, so that the threaded cylinder moves smoothly. When the threaded cylinder moves, it will push the strip groove to move.

[0021] Preferably, the storage component includes a frame, a grid plate, and a discharge plate. The frame is embedded inside the workbench, the grid plate is fixedly installed on the top of the frame, and the discharge plate is fixedly installed inside the frame.

[0022] By adopting the above solution, the frame provides installation space for the grating plate. Impurities generated during welding and grinding will fall onto the discharge plate, and the discharge plate will allow the debris to flow into the waste trough for collection and storage.

[0023] Preferably, a movable groove is fixedly provided at the bottom of the frame, a square plate is inserted inside the movable groove, a waste trough is provided inside the square plate, and the waste trough is located on one side of the discharge plate.

[0024] By adopting the above method, when cleaning the debris collected inside the waste trough, pulling the square plate will move the square plate to the outside through the movable groove, thereby cleaning the collected debris.

[0025] Preferably, the discharge plate is inclined.

[0026] The beneficial effects of this invention are as follows: 1. The steel structure welding support fixture of the present invention facilitates grinding of the weld joint through a grinding belt, thereby improving the quality of the weld. The operation of motor No. 3 drives the rotation of threaded rod No. 3, causing the threaded cylinder to move. The movement of the threaded cylinder pushes the strip groove to move, which in turn moves the grinding belt. After the grinding belt moves below the grinding point, the position of the strip frame can be adjusted by controlling the operation of the electric push rod, which in turn moves the grinding belt. The position of the grinding belt is manually determined, and after the grinding belt contacts the weld joint, the drive motor is activated. Through the transmission shaft, the grinding belt moves, thus grinding the weld joint of the workpiece. This effectively removes welding marks and defects, making the weld surface smooth and flat, improving the overall appearance, and providing a smooth foundation for subsequent surface treatments such as painting and spraying, ensuring adhesion and effectiveness.

[0027] 2. The support fixture for steel structure welding described in this invention facilitates cleaning of the workpiece and cooling of the weld area through the provided fan and spray nozzles. The fan generates airflow, which enters the telescopic hose and then flows into the distribution groove. After entering the distribution groove, the airflow is directed to the workpiece surface through the spray nozzles, thereby cleaning the workpiece and cooling it, thus improving the quality of the weld.

[0028] 3. The steel structure welding support fixture of the present invention has a waste trough for collecting debris generated during welding or grinding of the workpiece. Impurities generated during welding and grinding will fall onto the discharge plate. The discharge plate will cause the debris to flow into the waste trough for collection and storage.

A first mounting bracket 3 and a second mounting bracket 4 are symmetrically arranged on the top of the workbench 1. The first mounting bracket 3 is fixedly connected to the top of the workbench 1. An L-shaped bracket 17 is symmetrically connected to the second mounting bracket 4. A driving mechanism for moving the L-shaped bracket 17 is provided inside the workbench 1. A storage component for collecting waste materials is also provided inside the workbench 1. Both the first mounting bracket 3 and the second mounting bracket 4 are equipped with clamping mechanisms. Square slots 23 are symmetrically installed on the workbench 1. A storage slot 24 is fixedly connected to one end of each square slot 23. A strip-shaped groove 30 is provided inside the storage slot 24. An electric push rod 31 is fixedly installed inside the strip-shaped groove 30. A strip frame 32 is provided, and the telescopic rod of the electric push rod 31 is fixedly connected to the strip frame 32. A cleaning component is provided on the strip frame 32. A grinding belt 33 is arranged around the inside of the strip frame 32 via a drive shaft. A drive motor 34 is provided inside the strip frame 32, and the output end of the drive motor 34 is connected to the drive shaft supporting the grinding belt 33. A wind mechanism is provided inside the strip groove 30, and an adjustment mechanism for adjusting the position of the strip groove 30 is provided inside the square groove 23. A controller is provided on the side of the workbench 1, which is electrically connected to the electrical components on the steel structure welding support fixture to control the operation of the electrical components. When the steel structure welding support fixture is used to fix and weld the steel structure to be welded, the first mounting frame 3 and the second mounting frame 4 are used for the welding. The clamping mechanism can fix two workpieces to be welded. Then, the drive mechanism moves to adjust the position of the L-shaped bracket 17. The movement of the L-shaped bracket 17 can adjust the position of the second mounting bracket 4. When the second mounting bracket 4 moves, it pushes the fixed and clamped workpiece to move, thereby making the weld joint of the two workpieces fit tightly together. Then, the external welding machine is moved to the welding position, and the workpiece can be welded. The angle of the workpiece can be adjusted by the drive mechanism, and the welding machine can weld different positions of the workpiece, which improves the flexibility of the support fixture for steel structure welding. After adjusting the angle of the workpiece to be welded, the welding marks can be rotated downwards. The cleaning component can clean the surface of the workpiece and perform... Air cooling simultaneously activates the electric push rod 31, which moves the strip groove 30. The movement of the strip groove 30 drives the grinding belt 33 to move. Once the grinding belt 33 is below the grinding location, the position of the strip frame 32 can be adjusted by controlling the electric push rod 31, which in turn moves the grinding belt 33. The position of the grinding belt 33 is manually determined, and after the grinding belt 33 contacts the weld, the drive motor 34 is activated. Through the transmission shaft, the grinding belt 33 moves, thus grinding the weld of the workpiece. This effectively removes welding marks and defects, making the weld surface smooth and flat, improving the overall appearance, and providing a smooth foundation for subsequent surface treatments such as coating and spraying, ensuring adhesion and effectiveness.

[0034] Furthermore, a side plate 37 is fixedly installed on the top of the strip frame 32, and the side plate 37 is located on one side of the grinding belt 33. The cleaning component includes a diversion channel 35 and spray holes 36. The diversion channel 35 is symmetrically embedded inside the strip frame 32, and the spray holes 36 are arrayed on the diversion channel 35. The grinding debris from the grinding belt 33 will fall onto the side plate 37, and the grinding debris will slide off through the side plate 37. After the air enters the diversion channel 35, the air will flow to the surface of the workpiece through the spray holes 36, thereby cleaning the workpiece.

[0035] Furthermore, the wind power mechanism includes a wind box 38, a filter plate 39, a fan 40, and a telescopic hose 41. The wind box 38 is embedded inside the strip groove 30. The filter plate 39 is fixedly installed on one side of the wind box 38. The fan 40 is fixedly installed inside the wind box 38. One end of the telescopic hose 41 is connected to the output end of the fan 40, and the other end of the telescopic hose 41 is connected to the diversion groove 35. When the fan 40 operates, it generates airflow. After the airflow enters the telescopic hose 41, it will flow into the diversion groove 35 through the telescopic hose 41.

[0036] Furthermore, a support leg 2 is fixedly installed at the bottom of the worktable 1. The clamping mechanism includes a cylinder 5, a rotating disk 6, an annular groove 7, a limiting ring 8, a servo motor 15, and a clamping assembly. Both mounting brackets 1 and 2 have cylinders 5 fixedly installed inside them. The rotating disk 6 is rotatably mounted inside the cylinder 5. The annular groove 7 is mounted on the rotating disk 6. The limiting ring 8 is rotatably mounted inside the annular groove 7 and is fixedly connected to the inner wall of the cylinder 5. The servo motor 15 is fixedly mounted inside the cylinder 5, and its output end is fixedly connected to the center of the rotating disk 6. The clamping assembly is mounted on the rotating disk 6. The worktable 1 is supported by the support leg 2. When the clamping mechanism moves, after the workpiece is fixedly clamped by the clamping assembly, the servo motor 15 drives the rotating disk 6 to rotate. Through the cooperation of the annular groove 7 and the limiting ring 8, the rotating disk 6 rotates smoothly. The rotation of the rotating disk 6 drives the clamping assembly to rotate. Therefore, when the clamping assembly rotates, the angle of the clamped workpiece can be adjusted, facilitating welding at different positions of the workpiece.

[0037] Furthermore, the clamping assembly includes a sliding groove 9, a first threaded rod 10, a clamping block 11, a threaded ring 12, a micro motor 13, and a guide rod 14. The sliding groove 9 is embedded inside the rotating disk 6. The first threaded rod 10 is rotatably disposed inside the corresponding sliding groove 9. The clamping block 11 is disposed inside the corresponding sliding groove 9. The threaded ring 12 is fixedly disposed inside the clamping block 11 and is threadedly connected to the first threaded rod 10. The micro motor 13 is fixedly installed inside the rotating disk 6, and the output end of the micro motor 13 is fixed to one end of the first threaded rod 10. The guide rod 14 is fixedly installed inside the sliding groove 9 and passes through the clamping block 11. When the clamping assembly positions and clamps the workpiece, after the workpiece is placed on one side of the clamping block 11, the micro motor 13 will drive the first threaded rod 10 to rotate. The rotation of the first threaded rod 10 will adjust the position of the clamping block 11 through the threaded ring 12. The symmetrically arranged clamping blocks 11 move in opposite directions. The guide rod 14 will guide the clamping blocks 11 to move smoothly, and thus the workpiece can be positioned and clamped through the clamping block 11.

[0038] Furthermore, the drive mechanism includes a slide 16, a connecting plate 18, a guide rod 19, a threaded hole 20, a second threaded rod 21, and a second motor 22. The slide 16 is embedded inside the worktable 1. The connecting plate 18 is disposed inside the slide 16, and both ends of the connecting plate 18 are fixedly connected to the L-shaped bracket 17. The guide rod 19 passes through the interior of the connecting plate 18 and is fixedly connected to the inner wall of the slide 16. The threaded hole 20 is disposed inside the connecting plate 18, and the second threaded rod 21 is threadedly connected to the threaded hole 20. The second motor... 22 is fixedly installed inside the slide groove 16, and the output end of the second motor 22 is fixedly connected to one end of the second threaded rod 21. When the drive mechanism moves, the second motor 22 will work and drive the second threaded rod 21 to rotate. When the second threaded rod 21 rotates, it will move the connecting plate 18 through the threaded hole 20. The guide rod 19 will guide the connecting plate 18 to move smoothly. When the connecting plate 18 moves, it will drive the L-shaped bracket 17 to move, and then the L-shaped bracket 17 will drive the second mounting bracket 4 to move.

[0039] Furthermore, the adjustment mechanism includes a No. 3 motor 25, a No. 3 threaded rod 26, a threaded cylinder 27, a guide block 28, and a limiting rod 29. The No. 3 motor 25 is fixedly installed inside the square groove 23. One end of the No. 3 threaded rod 26 is fixedly connected to the output end of the No. 3 motor 25. The threaded cylinder 27 is threadedly connected to the No. 3 threaded rod 26, and one end of the threaded cylinder 27 is fixedly connected to the strip groove 30. The guide block 28 is fixedly connected to the threaded cylinder 27. The limiting rod 29 passes through the guide block 28 and is fixedly connected to the inner wall of the square groove 23. When the No. 3 motor 25 operates, it drives the No. 3 threaded rod 26 to rotate. When the No. 3 threaded rod 26 rotates, it causes the threaded cylinder 27 to move. The movement of the threaded cylinder 27 causes the guide block 28 to slide on the limiting rod 29. Thus, through the cooperation of the guide block 28 and the limiting rod 29, the threaded cylinder 27 is guided, allowing it to move smoothly. When the threaded cylinder 27 moves, it pushes the strip groove 30 to move.

[0040] Furthermore, the storage components include a frame 42, a grid plate 43, and a discharge plate 44. The frame 42 is embedded inside the workbench 1, the grid plate 43 is fixedly installed on the top of the frame 42, and the discharge plate 44 is fixedly installed inside the frame 42. The discharge plate 44 is inclined, and the frame 42 provides installation space for the grid plate 43. Impurities generated during welding and grinding will fall onto the discharge plate 44, and the debris will flow into the waste trough 47 for storage through the discharge plate 44.

[0041] Furthermore, a movable groove 45 is fixedly provided at the bottom of the frame 42. A square plate 46 is inserted inside the movable groove 45. A waste trough 47 is provided inside the square plate 46, and the waste trough 47 is located on one side of the discharge plate 44. When the debris collected in the waste trough 47 is to be removed, the square plate 46 is pulled, and the square plate 46 will be moved to the outside through the movable groove 45, so that the collected debris can be removed.

[0042] Working principle: First, when using the steel structure welding support fixture to fix the steel structure to be welded, the clamping mechanisms on mounting bracket 3 and mounting bracket 4 fix the two workpieces to be welded. After placing the workpiece on one side of the clamping block 11, the micro motor 13 drives the first threaded rod 10 to rotate. The rotation of the first threaded rod 10 adjusts the position of the clamping block 11 through the threaded ring 12. The symmetrically arranged clamping blocks 11 move in opposite directions. The guide rod 14 guides the clamping blocks 11, allowing them to move smoothly. Thus, the clamping blocks 11 can position and clamp the workpiece. The second motor 22 drives the second threaded rod 21 to rotate. When the second threaded rod 21 rotates, it engages with the threaded hole 20... The connecting plate 18 is moved, guided by the guide rod 19, ensuring its smooth movement. This movement of the connecting plate 18 moves the L-shaped bracket 17, which in turn moves the second mounting bracket 4. The second mounting bracket 4 then moves the clamped workpiece, allowing the two workpieces to fit tightly together at the welding point. Next, an external welding machine is moved to the welding point for welding. The servo motor 15 drives the rotating disk 6 to rotate. Through the cooperation of the annular groove 7 and the limit ring 8, the rotating disk 6 rotates smoothly. The rotation of the rotating disk 6 drives the clamping assembly to rotate, allowing adjustment of the angle of the clamped workpiece and facilitating welding at different positions on the workpiece. The angle of the workpiece is adjusted, and then welding can be performed on different positions of the workpiece by the welding machine. This improves the flexibility of the support fixtures used for steel structure welding. After adjusting the angle of the workpiece, the welding marks can be rotated downwards. The fan 40 generates airflow, which enters the telescopic hose 41 and then flows into the diversion groove 35. After entering the diversion groove 35, the airflow is directed to the workpiece surface through the nozzle 36, thus cleaning and cooling the workpiece. At the same time, the electric push rod 31 is activated, which moves the strip groove 30. The movement of the strip groove 30 drives the grinding belt 33 to move. After the grinding belt 33 moves below the grinding point, it is then... The electric push rod 31 is controlled to adjust the position of the strip frame 32, which in turn moves the grinding belt 33. The position of the grinding belt 33 is manually determined, and once it contacts the weld joint, the drive motor 34 is activated. Through the transmission shaft, the grinding belt 33 moves, effectively grinding the weld joint of the workpiece. This effectively removes welding marks and defects, resulting in a smooth weld surface, improving the overall appearance, and providing a smooth base for subsequent surface treatments such as coating and spraying, ensuring adhesion and effectiveness. Impurities generated during welding and grinding fall onto the discharge plate 44, which allows debris to flow into the waste trough 47 for collection and storage. The debris collected in the waste trough 47 is then removed.Pulling the square panel 46 will move it to the outside via the movable slot 45, allowing for the removal of collected debris.
