Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a laser welding processing equipment for steel structure manufacturing. Background Technology

[0002] As a core load-bearing system in modern architecture, bridges, and industrial plants, the welding quality of steel structures directly affects the safety and durability of the overall structure. Among these, H-beams, due to their excellent cross-sectional mechanical properties, have become one of the most widely used steel structure forms. Laser welding technology, with its significant advantages such as high energy density, fast welding speed, small heat-affected zone, and controllable deformation, has shown great potential in high-end steel structure manufacturing. However, applying laser welding technology to components like H-beams, which are assembled from webs and upper and lower flanges, places extremely stringent requirements on tooling fixtures and production processes.

[0003] In the existing technology for welding H-beams, the thermal stress and deformation caused by local high temperature can easily lead to dynamic changes in the gap between the originally positioned web and flange. When clamping materials, the existing device cannot guarantee a constant gap throughout the entire length of the weld. Furthermore, when flipping the material, the clamp may loosen or the relative displacement inside the component may occur due to its own weight or inertia. Summary of the Invention

[0004] The purpose of this invention is to provide a laser welding processing equipment for steel structure manufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser welding processing equipment for steel structure manufacturing, comprising a chassis and a clamping assembly. The clamping assembly is provided on both sides above the chassis. The clamping assembly includes a frame. The frame is symmetrically arranged on both sides above the chassis, and the frame is symmetrically provided with shift grooves on both sides. The shift grooves are symmetrically provided with sliding grooves on both sides, and a slider is slidably connected in the sliding grooves. The upper inner side of the frame is symmetrically provided with an upper clamping plate, and the lower inner side of the frame is symmetrically provided with a lower clamping plate. A shaft is rotatably connected in the shift groove, and double gears are symmetrically connected on both sides of the shaft. A rack is provided on one side of the double gears, and a toothed bar is provided on the other side of the double gears. A pressure block is connected between the racks.

[0006] Furthermore, the upper and lower clamping plates are connected to the rack and pinion respectively via sliders, and both the upper and lower clamping plates are slidably connected to the frame via sliders. A total of eight sliding grooves are symmetrically arranged on the inner side of the frame.

[0007] Furthermore, the double gear consists of two gears of different diameters, and the rack and pinion mesh with the pinion and pinion of the double gear, respectively. The rack and pinion are both L-shaped, and they are slidably connected to the frame by means of a sliding groove.

[0008] Furthermore, a clamping groove is provided in the middle of the frame, and clamping springs are symmetrically connected in the clamping groove, with a clamping rod connected to one side of each clamping spring.

[0009] Furthermore, the clamping rod is T-shaped and is elastically connected to the frame via a clamping spring. The clamping rod is slidably connected to the frame via a clamping groove, and one end of the clamping rod located inside the frame contacts the inclined surface of the pressure block.

[0010] Furthermore, a stop wheel is connected to the middle of the shaft, and a locking block is provided on one side of the stop wheel. A centrifugal block is provided on the other side of the stop wheel, and a hook block is provided on one side of the centrifugal block. An electromagnet is provided on one side of the locking block. The locking block and the centrifugal block are engaged with the stop wheel.

[0011] Furthermore, both the locking block and the centrifugal block are provided with a stop spring on the side away from the stop wheel, and limit rods are symmetrically slidably connected on both sides of the locking block and the centrifugal block. The limit rods are connected to the frame, and both the locking block and the centrifugal block are elastically connected to the transfer groove through the stop spring.

[0012] Furthermore, a sliding frame is symmetrically arranged in the middle of the chassis, and a vertical plate is slidably connected inside the sliding frame. A main shaft is rotatably connected to the lower part of the vertical plate, and a bracket is connected to the middle of the main shaft. The frame is connected to both sides of the bracket.

[0013] Furthermore, ratchet discs are symmetrically connected to both ends of the main shaft, and a rotating wheel is provided on the outer side of the ratchet disc, with a toothed column on one side of the rotating wheel.

[0014] Furthermore, the chassis is symmetrically connected with lifting rods at its four corners, and the upper end of the lifting rods is connected to a top plate. The top plate is symmetrically provided with openings on both sides, and the upright plate is slidably connected to the top plate through the openings. Two sets of laser welding mechanisms are symmetrically provided below the top plate.

[0015] This invention provides a laser welding processing equipment for steel structure manufacturing, which has the following advantages: During use, it can adaptively clamp the assembled and positioned H-beams and press the joints to ensure that the gap between the three plates remains stable when welding the joints, avoiding weld position drift during welding. After welding one side is completed, the material can be transferred while maintaining stable clamping, and flipped during the transfer process to weld the other side. At the same time, new material is fed into the device, thereby performing double-line welding to improve processing efficiency.

[0016] 1. In use, the assembled and positioned H-beam is placed horizontally into the frame, with its lower end placed on the lower clamping plate. Under the weight of the material, the lower clamping plate drives the upper clamping plate to descend via a rack, pinion, and gear, clamping the H-beam. Simultaneously, the connection between the vertical plates on both sides of the H-beam and the middle horizontal plate is exposed, facilitating welding. Because the two gears of the double gear have unequal diameters, the double gear can amplify the stroke of the pinion on the rack, making the rack's movement distance greater than the pinion's. This means the descent distance of the upper clamping plate is greater than that of the lower clamping plate. When the upper clamping plate presses firmly against the upper end of the H-beam, if the lower clamping plate tends to move, the rack will obstruct the rotation of the double gear, preventing the pinion and rack from moving further. Consequently, neither the upper nor lower clamping plate will continue to move, thus firmly clamping the two vertical plates of the H-beam.

[0017] 2. In this invention, as the rack descends, it drives the pressure block to slide the clamping rod, applying even force to the side of the H-beam. This pushes the H-beam to the center of the frame for centering, and the clamping rod holds the H-beam, pressing down on the joint of the three plates. This ensures that the gap between the three plates remains stable during welding, preventing weld position drift. When transferring and flipping materials, the centrifugal block and the locking block engage with the stop wheel sequentially. Thus, with the cooperation of the centrifugal block and the clamping block, the stop wheel prevents the shaft from rotating, avoiding the upper clamping plate from moving under the gravity of the H-beam after the frame is flipped, which would cause the clamping to loosen, resulting in material displacement, weld misalignment, or material falling. After the frame is flipped and stationary, the clamping block will remain engaged with the stop wheel under the action of gravity, thereby maintaining the clamping and pressing effect. After the material is welded after being flipped, the electromagnet is energized to attract the clamping block, which can release the clamping of the material, thus facilitating unloading.

[0018] 3. In this invention, after the frame is stationary and the materials are placed, the lifting rod drives the top plate to descend, bringing the laser welding mechanism below the top plate closer to the materials. The materials in the frames on both sides are then processed. After processing, the materials that have been welded on both sides are unloaded. The lifting rod then drives the top plate to rise, moving the laser welding mechanism away from the frame. When the top plate contacts the upper part of the vertical plate, the top plate drives the vertical plate to rise synchronously. The vertical plate can drive the support to rise synchronously via the main shaft. The frame moves synchronously with the main shaft via the support. During the rise of the vertical plate, the turning wheel, under the action of the toothed column, can drive the main shaft to rotate via the ratchet disc, thereby transferring the frame via the support. The materials that have only been welded on one side are transferred to the workstation on the other side. After the transfer is completed, the frame also drives the materials to flip synchronously, thereby processing the other side of the materials. Then, the lifting rod drives the top plate to descend, and the top plate can then drive the frames on both sides to return to their initial height via the vertical plate. Attached Figure Description

[0021] Please see Figures 1 to 7The present invention provides a technical solution: a laser welding processing equipment for steel structure manufacturing, including a chassis 1 and a clamping assembly 2. The clamping assembly 2 is provided on both sides above the chassis 1. The clamping assembly 2 includes a frame 201. The frames 201 are symmetrically arranged on both sides above the chassis 1, and the frames 201 are symmetrically provided with shift grooves 202 on both sides. The shift grooves 202 are symmetrically provided with sliding grooves 203 on both sides. The sliding grooves 203 are fitted and slidably connected with sliders 204. The upper inner side of the frame 201 is symmetrically provided with upper clamping plates 205, and the lower inner side of the frame 201 is symmetrically provided with lower clamping plates 206. The shift grooves 202 are rotatably connected with shafts 207, and the shafts 207 are symmetrically connected with double gears 208 on both sides. The double gears 208 are provided with racks 209 on one side and racks 210 on the other side. The racks 209 are connected with pressure blocks 211.

[0022] Please see Figures 1 to 6 The upper clamping plate 205 and the lower clamping plate 206 are connected to the rack 210 and the pinion 209 respectively via the slider 204. Both the upper clamping plate 205 and the lower clamping plate 206 are slidably connected to the frame 201 via the slider 204. Eight sliding grooves 203 are symmetrically arranged inside the frame 201. The double gear 208 consists of two gears of different diameters. The pinion 209 and the rack 210 mesh with the small gear and the large gear of the double gear 208 respectively. Both the pinion 209 and the rack 210 are L-shaped and are slidably connected to the frame 201 via the sliding groove 202. A clamping groove 3 is provided in the middle of the frame 201, and clamping springs 4 are symmetrically connected within the clamping groove 3. A clamping rod 5 is connected to one side of the clamping spring 4. The clamping rod 5 is T-shaped and... Rod 5 is elastically connected to frame 201 via clamping spring 4. The clamping rod 5 is slidably connected to frame 201 via clamping groove 3. One end of the clamping rod 5 located inside frame 201 is in contact with the inclined surface of pressure block 211. A stop wheel 6 is connected to the middle of shaft rod 207. A locking block 7 is provided on one side of the stop wheel 6. A centrifugal block 8 is provided on the other side of the stop wheel 6. A hook block 9 is provided on one side of the centrifugal block 8. An electromagnet 10 is provided on one side of the locking block 7. Both the locking block 7 and the centrifugal block 8 are engaged with the stop wheel 6. A stop spring 11 is provided on the side of the locking block 7 and the centrifugal block 8 away from the stop wheel 6. Limiting rods 12 are symmetrically slidably connected on both sides of the locking block 7 and the centrifugal block 8. The limiting rods 12 are connected to frame 201. Both the locking block 7 and the centrifugal block 8 are elastically connected to the shifting groove 202 via the stop spring 11. The specific operation is as follows: During use, the assembled and positioned H-beam is placed horizontally into the frame 201, and its lower end is placed on the lower clamping plate 206. Under the action of gravity, the lower clamping plate 206 drives the slider 204 to move in the slide groove 203, and the slider 204 drives the rack 209 to descend in the transfer groove 202. The rack 209 drives the shaft 207 to rotate in the transfer groove 202 through the small gear of the double gear 208. The large gear of the double gear 208 can then drive the rack 210 to descend in the transfer groove 202, and then drive the slider 204 to move the rack 210 to descend in the transfer groove 202. The upper clamping plate 205 descends to clamp the upper end of the H-beam. When the upper clamping plate 205 is pressed against the upper end of the H-beam, and the lower clamping plate 206 has a tendency to move, the rack 210 will obstruct the rotation of the double gear 208, preventing the rack 209 and the pinion 210 from moving further. This prevents the upper clamping plate 205 and the lower clamping plate 206 from moving further, thus firmly clamping the two vertical plates of the H-beam. As the rack 209 descends, it will drive the pressure block 211 to descend within the clamping groove 3, allowing the pressure block 211 to pass through its inclined... The clamping rod 5 slides within the clamping groove 3, stretching the clamping spring 4. As the clamping rod 5 moves, it applies balanced force to the side of the H-beam, pushing it to the center of the frame 201 and clamping it. During material transfer and flipping, the centrifugal block 8, under centrifugal force, first stretches the stop spring 11 and engages with the stop wheel 6. As the centrifugal block 8 moves, it drives the hook block 9, causing the inclined surface of the hook block 9 to push the locking block 7 closer to the stop wheel 6, engaging the locking block 7 with the stop wheel 6. The stop wheel 6, in cooperation with the centrifugal block 8 and the clamping block 7, prevents the shaft 207 from rotating. After the material is welded after being flipped, the electromagnet 10 is energized to attract the clamping block 7, causing it to detach from the stop wheel 6. Under the gravity of the H-beam, the upper clamping plate 205 descends and drives the lower clamping plate 206 to move through the double gear 208. At the same time, the pressure block 211 moves with the gear 209, releasing the pressure on the clamping rod 5. The clamping rod 5 rebounds under the action of the clamping spring 4. Since the lower clamping plate 206 moves a shorter distance than the upper clamping plate 205, the clamping of the material can be released.

[0023] Please see Figure 1 and Figures 4 to 7A sliding frame 13 is symmetrically arranged in the middle of the chassis 1, and a vertical plate 14 is slidably connected inside the sliding frame 13. A main shaft 15 is rotatably connected to the lower part of the vertical plate 14, and a bracket 16 is connected in the middle of the main shaft 15. A frame 201 is connected to both sides of the bracket 16. A ratchet disk 17 is symmetrically connected to both ends of the main shaft 15, and a turning wheel 18 is arranged on the outside of the ratchet disk 17. A toothed column 19 is arranged on one side of the turning wheel 18. Lifting rods 20 are symmetrically connected at the four corners of the chassis 1, and a top plate 21 is connected to the upper end of the lifting rods 20. A through-hole 22 is symmetrically arranged on both sides of the top plate 21, and the vertical plate 14 is slidably connected to the top plate 21 through the through-hole 22. Two sets of laser welding mechanisms are symmetrically arranged below the top plate 21. The specific operation is as follows: After the frame 201 is stationary and the material is placed, the lifting rod 20 drives the top plate 21 to descend, bringing the laser welding mechanism below the top plate 21 closer to the material to process the material inside the frames 201 on both sides. During this process, the upright plate 14 can restrict the top plate 21 through the through-hole 22 to prevent it from tilting. After processing, the material with both sides welded is unloaded, and the lifting rod 20 drives the top plate 21 to rise, moving the laser welding mechanism away from the frame 201. When the top plate 21 contacts the upper end of the upright plate 14, the top plate 21 drives the upright plate 14 to rise synchronously. The sliding frame 13 can restrict the upright plate 14 to prevent it from tilting, and the upright plate 14 can drive the bracket 16 to rise synchronously through the main shaft 15. The frame 201 is connected to the main shaft 15 through the bracket 16. During the synchronous movement, as the upright plate 14 rises, the tilting wheel 18, under the action of the toothed column 19, can drive the main shaft 15 to rotate 180° via the ratchet disc 17, thereby transferring the frame 201 via the bracket 16. The material that has only been welded on one side is transferred to the workstation on the other side. After the transfer is completed, the frame 201 also drives the material to rotate synchronously, thereby processing the other side of the material. Then, the lifting rod 20 drives the top plate 21 to descend, and the top plate 21 can drive the frames 201 on both sides to return to the initial height via the upright plate 14. During this process, because of the ratchet disc 17, the main shaft 15 will not rotate with the tilting wheel 18, thereby ensuring the stability of the frame 201. Then, new material is fed into the empty frame 201, and processing can continue.

[0024] In summary, when using this laser welding processing equipment for steel structure manufacturing, the assembled and positioned H-beams are first placed horizontally into the frame 201, and their lower ends are placed on the lower clamping plate 206. Under the action of gravity, the lower clamping plate 206 drives the slider 204 to move in the slide groove 203, and the slider 204 drives the rack 209 to descend in the transfer groove 202. The rack 209 drives the shaft 207 to rotate in the transfer groove 202 through the small gear of the double gear 208. The large gear of the double gear 208 can then drive the rack 210 to descend in the transfer groove 202, and then drive the upper clamping plate 205 to descend through the slider 204 to clamp the upper end of the H-beams. At the same time, the connection between the vertical plates on both sides of the H-beams and the middle horizontal plate is exposed, which is convenient for welding. Because the two gears of the double gear 208 have different diameters, the double gear 208 can amplify the stroke of the rack 209 on the rack 210, making the moving distance of the rack 210 greater than that of the rack 209. That is, the descending distance of the upper clamping plate 205 is greater than that of the lower clamping plate 206. When the upper clamping plate 205 is pressed against the upper end of the H-beam, and the lower clamping plate 206 has a tendency to move, the rack 210 will obstruct the rotation of the double gear 208, so that neither the rack 209 nor the rack 210 can continue to move, and neither the upper clamping plate 205 nor the lower clamping plate 206 can continue to move, thereby firmly clamping the two vertical plates of the H-beam. As the rack 209 descends, it drives the pressure block 211 to descend within the clamping groove 3. This causes the pressure block 211 to press the clamping rod 5 through its inclined surface, allowing it to slide within the clamping groove 3 and stretching the clamping spring 4. The clamping groove 3 can restrict the clamping rod 5, preventing it from tilting during movement. When the clamping rod 5 moves, it can apply a balanced force to the side of the H-beam, thereby pushing the H-beam to the center of the frame 201 for centering. The clamping rod 5 also clamps the H-beam, pressing the joint of the three plates together to ensure that the gap between the three plates remains stable when welding the joint, preventing the weld position from drifting during welding. After the frame 201 is stationary and the material is placed, the lifting rod 20 drives the top plate 21 to descend, bringing the laser welding mechanism below the top plate 21 closer to the material to process the material inside the frame 201. During this process, the upright plate 14 can restrict the top plate 21 through the through-hole 22 to prevent it from tilting. After processing, the lifting rod 20 drives the top plate 21 to rise, moving the laser welding mechanism away from the frame 201. When the top plate 21 contacts the upper end of the upright plate 14, the top plate 21 drives the upright plate 14 to rise synchronously. The sliding frame 13 can restrict the upright plate 14 to prevent it from tilting. The upright plate 14 can drive the support 16 to rise synchronously through the main shaft 15. The frame 201 moves synchronously with the main shaft 15 through the support 16. During the rise of the upright plate 14, the turning wheel 18, under the action of the toothed column 19, can drive the main shaft 15 to rotate 180° through the ratchet disc 17, thereby transferring the frame 201 through the support 16 and transferring the material that has only been welded on one side to the workstation on the other side. After the transfer is completed, the frame 201 also drives the material to flip synchronously, so that the other side of the material can be processed. Then the lifting rod 20 drives the top plate 21 to descend, and the top plate 21 can drive the frames 201 on both sides to fall back to the initial height through the upright plate 14. During this process, because of the ratchet disc 17, the main shaft 15 will not rotate with the flipping wheel 18, thus ensuring the stability of the frame 201. Then, new material is fed into the empty frame 201, and processing can continue. When transferring and flipping materials, the centrifugal block 8 stretches the stop spring 11 under centrifugal force and engages with the stop wheel 6. When the centrifugal block 8 moves, it drives the hook block 9 to move, thereby pushing the clamping block 7 closer to the stop wheel 6 through the inclined surface of the hook block 9, so that the clamping block 7 engages with the stop wheel 6. Thus, the stop wheel 6, with the cooperation of the centrifugal block 8 and the clamping block 7, prevents the shaft 207 from rotating. This avoids the upper clamping plate 205 from moving under the gravity of the H-beam after the frame 201 is flipped, which would cause the clamping to loosen, resulting in material displacement, weld seam offset, or material falling. During the movement of the clamping block 7 and the centrifugal block 8, the limiting rod 12 can prevent them from tilting and failing to engage with the stop wheel 6. After the frame 201 is flipped and stationary, the clamping block 7 will remain engaged with the stop wheel 6 under the action of gravity, thereby maintaining the clamping and pressing effect. After the material is welded after being flipped, the electromagnet 10 is energized to attract the clamping block 7, causing it to detach from the stop wheel 6. Under the gravity of the H-beam, the upper clamping plate 205 descends and drives the lower clamping plate 206 to move through the double gear 208. At the same time, the pressure block 211 moves with the rack 209, releasing the pressure on the clamping rod 5. The clamping rod 5 rebounds under the action of the clamping spring 4. Since the lower clamping plate 206 moves a shorter distance than the upper clamping plate 205, the clamping of the material can be released, thus facilitating unloading.
