Description

Technical Field

[0001] This invention relates to the field of steel structure welding technology, and in particular to a positioning control device and method for welding double shear plate joints of heavy-duty box-type steel structures. Background Technology

[0002] To facilitate building support, box-type steel structures assembled on-site are often used as reinforcement tools. These steel columns also need to be installed using joints, and the double shear plates in heavy-duty box-type steel structures need to be assembled and welded on specialized welding machines.

[0003] Currently, most welding machine tools still use a semi-automatic adjustment method, which requires manual support to hold the shear plate together for welding. This is not only unsafe but also makes it difficult to maintain balance, and the accuracy of the processed node structure is also difficult to guarantee. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: most welding machine tools at present still adopt a semi-automatic adjustment method, which requires manual support to hold the shear plate together for welding. This is not only unsafe but also difficult to maintain balance, and the accuracy of the processed node structure is difficult to guarantee. The invention proposes a positioning control device and method for welding double shear plate nodes of heavy-duty box-type steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning control device for welding double shear plate nodes of heavy-duty box-type steel structure includes a platform, a welding robotic arm is fixedly installed on the back of the platform, a fixing plate is horizontally fixedly installed on the upper surface of the platform, a first mounting opening is symmetrically and horizontally opened on the surface of the fixing plate, a first threaded rod is horizontally and rotatably installed in the first mounting opening, and a first positioning plate is threadedly sleeved on the first threaded rod.

[0007] The first positioning plate has a second mounting opening horizontally on its surface. A second threaded rod is horizontally and rotatably mounted in the second mounting opening. A second positioning plate is threaded onto the second threaded rod. The ends of the first threaded rod and the second threaded rod pass through the fixing plate and the first positioning plate, respectively, and are both fixedly fitted with adjusting wheels.

[0008] Preferably, the platform surface is provided with an installation groove, and the upper surface of the platform is provided with symmetrical vertical openings that communicate with the installation groove. The installation groove is provided with an adsorption component for adsorbing and shearing plates.

[0009] Preferably, the adsorption assembly includes a T-shaped slide plate, two symmetrically and vertically fixed hollow cylinders on the upper surface of the slide plate, and two suction cups respectively fixedly installed at the top of the two hollow cylinders. The two hollow cylinders are respectively located in two openings. The lower surface of the slide plate is symmetrically provided with rotating ports that are respectively connected to the inside of the two hollow cylinders. A desorption component is provided in the rotating port. The desorption component is used to release the adsorption of the suction cups. A third threaded rod is vertically and rotatably installed in the mounting groove. The slide plate is threadedly sleeved on the third threaded rod and its rotation is restricted by a limiting component.

[0010] Preferably, the desorption component includes a rotating shaft and a sealing plate. The rotating shaft is rotatably and sealed inside the rotating port, and one end of the rotating shaft located inside the hollow cylinder is fixedly connected to the surface of the sealing plate via a connecting rod. The surface of the hollow cylinder has a vent, and the sealing plate is used to cover the vent. A gear is fixedly installed on the external end of the rotating shaft, and the gear is connected to the sliding plate via an elastic component.

[0011] Preferably, the limiting component includes a limiting rod that is vertically fixed in the mounting groove, and the sliding plate is slidably sleeved on the limiting rod.

[0012] Preferably, the elastic component includes a torsion spring sleeved on the rotating shaft, with its two ends fixedly connected to the slide plate and the gear, respectively.

[0013] Preferably, a first spring rod is fixedly installed on the surface of the skateboard, a U-shaped movable plate is fixedly installed at one end of the first spring rod, and rack rods are symmetrically fixedly installed on the surface of the movable plate, with the two rack rods respectively meshing with two gears.

[0014] Preferably, a groove is horizontally formed on the upper surface of the fixed plate, a telescopic rod is slidably installed in the groove, and a cleaning plate is fixedly installed at the top of the telescopic rod through a connecting rod.

[0015] Preferably, the cleaning plate has multiple water tanks on its upper surface, each containing cleaning fluid. A piston plate is slidably and sealed within each water tank. A water inlet communicating with the outside is located at the bottom of each water tank. Straight rods are fixedly installed on the upper surface of the piston plate, and rectangular plates are fixedly installed at the top ends of the multiple straight rods. A mounting plate is fixedly installed on the side wall of the cleaning plate, and multiple second spring rods are fixedly installed on the upper surface of the mounting plate. The top ends of the multiple second spring rods are all fixedly connected to the lower surface of the rectangular plate.

[0016] The method for positioning and controlling the welding of double shear plate nodes in heavy-duty box-type steel structures comprises the following steps: First, the shear plate to be welded is placed on the upper surface of the platform and positioned between two first positioning plates. Then, one side of the shear plate is tightly pressed against the surface of the fixed plate, and the welding node of the shear plate is positioned at a suitable welding position. At this time, the first threaded rod is rotated, and the first positioning plate threaded onto the first threaded rod will move laterally until both first positioning plates are tightly pressed against the shear plate. Then, the second threaded rod is rotated, and the second positioning plate threaded onto the second threaded rod will move laterally until both second positioning plates are tightly pressed against the shear plate. At this time, the shear plate is positioned in the auxiliary positioning space composed of the fixed plate, the two first positioning plates, and the two second positioning plates. No manual support is required, which improves the stability of the positioned shear plate and ensures the accuracy of the processed double shear plate node structure. It can also assist in positioning shear plates of different sizes.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Through the cooperation between the fixed plate, the first threaded rod, the first positioning plate, the second threaded rod and the second positioning plate, the shear plate can be quickly positioned without manual support, which improves the stability of the positioning shear plate and ensures the accuracy of the processed double shear plate node structure. It can also be used to position shear plates of different sizes, making it highly practical.

[0019] 2. The first and second positioning plates can position the shear plate laterally, while the adsorption component can position the shear plate vertically to prevent it from moving in the vertical direction. Furthermore, if the positioning of the shear plate by the first and second positioning plates is accidentally released, the shear plate will still be in the positioned state under the action of the adsorption component and will not move laterally.

[0020] 3. After the shear plate is positioned, the telescopic rod can be controlled to move the cleaning plate laterally back and forth. During the movement, the cleaning plate can remove dust or impurities from the surface of the shear plate, thus preventing dust or impurities from affecting the quality of the joint welding.

[0021] 4. During the horizontal reciprocating movement of the cleaning plate, multiple piston plates can be controlled to move vertically, causing the cleaning fluid in multiple water tanks to be sprayed out from multiple water outlets and act on the surface of the shearing plate, thus improving the effect of removing dust and impurities.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-9The positioning control device for welding double shear plate nodes of heavy-duty box-type steel structure includes a platform 1, a welding robotic arm 2 fixedly installed on the back of the platform 1, a fixing plate 3 horizontally fixedly installed on the upper surface of the platform 1, a first installation port 4 symmetrically and horizontally opened on the surface of the fixing plate 3, a first threaded rod 5 horizontally rotatably installed in the first installation port 4, and a first positioning plate 6 threadedly sleeved on the first threaded rod 5.

[0034] The surface of the first positioning plate 6 has a second mounting opening 7 horizontally. A second threaded rod 8 is horizontally rotatably installed in the second mounting opening 7. A second positioning plate 9 is threaded onto the second threaded rod 8. The ends of the first threaded rod 5 and the second threaded rod 8 pass through the fixing plate 3 and the first positioning plate 6 respectively, and are both fixedly fitted with adjusting wheels 10.

[0035] First, place the shear plate to be welded on the upper surface of the platform 1, positioning it between the two first positioning plates 6. Then, control one side of the shear plate to be tightly pressed against the surface of the fixed plate 3, ensuring the welding joint of the shear plate is at the appropriate welding position. At this point, rotate the first threaded rod 5, causing the first positioning plate 6, threaded onto the first threaded rod 5, to move laterally until both first positioning plates 6 are tightly pressed against the shear plate. Then, rotate the second threaded rod 8, causing the second positioning plate 9, threaded onto the second threaded rod 8, to move laterally until both second positioning plates 9 are tightly pressed against the shear plate. At this point, the shear plate is positioned within the auxiliary positioning space formed by the fixed plate 3, the two first positioning plates 6, and the two second positioning plates 9. No manual support is required, improving the stability of the positioned shear plate and ensuring the accuracy of the processed double shear plate joint structure. Furthermore, it can assist in positioning shear plates of different sizes, making it highly practical.

[0036] The platform 1 has a mounting groove 11 on its surface. Symmetrically vertically arranged openings 12 on the upper surface of the platform 1 connect to the mounting groove 11. The mounting groove 11 contains an adsorption assembly for adsorbing shear plates. The adsorption assembly includes a T-shaped sliding plate 13, two symmetrically vertically fixed hollow cylinders 14 on the upper surface of the sliding plate 13, and two suction cups 15 respectively fixed to the tops of the two hollow cylinders 14. The two hollow cylinders 14 are located within the two openings 12. Symmetrically arranged rotating ports on the lower surface of the sliding plate 13 connect to the inside of the two hollow cylinders 14. A desorption component is provided within the rotating port to release the suction from the suction cups 15. The desorption component includes a rotating shaft 17 and a sealing plate 18. The rotating shaft 17 is rotatably and sealingly installed within the rotating port. One end of the hollow cylinder 14 is fixedly connected to the surface of the sealing plate 18 via a connecting rod. The surface of the hollow cylinder 14 has a vent 19, and the sealing plate 18 is used to cover the vent 19. A gear 20 is fixedly installed at the external end of the rotating shaft 17. The gear 20 is connected to the slide plate 13 via an elastic component. The elastic component includes a torsion spring 22 sleeved on the rotating shaft 17. The two ends of the torsion spring 22 are fixedly connected to the slide plate 13 and the gear 20, respectively. A third threaded rod 16 is vertically rotatably installed in the mounting groove 11. The slide plate 13 is threadedly sleeved on the third threaded rod 16 and its rotation is restricted by a limiting component. The limiting component includes a limiting rod 21 vertically fixedly installed in the mounting groove 11. The slide plate 13 is slidably sleeved on the limiting rod 21.

[0037] After the shear plate is positioned by the first positioning plate 6 and the second positioning plate 9, the third threaded rod 16 can be rotated. The slide plate 13, threaded onto the third threaded rod 16, will move vertically along with the two hollow cylinders 14 under the restraint of the limiting rod 21 until the suction cup 15 at the top of the hollow cylinder 14 is tightly pressed against the lower surface of the shear plate. The suction cup 15 will deform under the pressure, and the gas inside the suction cup 15 will slip out from the gap between the suction cup 15 and the contact surface of the shear plate, thus completing the adsorption of the shear plate. The first positioning plate 6 and the second positioning plate 9 can position the shear plate laterally, while the two suction cups 15 can position the shear plate vertically after adsorption, preventing it from moving vertically. Furthermore, if the positioning of the shear plate by the first positioning plate 6 and the second positioning plate 9 is accidentally released, the shear plate will still be in a positioned state under the adsorption of the suction cups 15 and will not move laterally.

[0038] When it is necessary to release the suction cup 15, simply rotate the gear 20 to control the rotating shaft 17 to rotate the sealing plate 18 until the sealing plate 18 no longer covers the vent 19. At this time, the gas in the outside will enter the hollow cylinder 14 through the vent 19, thereby releasing the suction cup 15. This is convenient and quick. When the gear 20 is released, the gear 20, rotating shaft 17 and sealing plate 18 will quickly rotate and reset under the elastic potential energy of the torsion spring 22, and the sealing plate 18 will cover the vent 19 again.

[0039] A first spring rod 23 is fixedly installed on the surface of the slide plate 13. A U-shaped movable plate 24 is fixedly installed at one end of the first spring rod 23. A rack rod 25 is symmetrically fixedly installed on the surface of the movable plate 24. The two rack rods 25 are respectively meshed with two gears 20.

[0040] When it is necessary to release the suction cup 15, simply push the moving plate 24 towards the slide plate 13. At this time, the two rack rods 25 will move together, and the two gears 20 that are respectively connected to the two rack rods 25 will rotate. This will control the two sealing plates 18 to rotate together, thus releasing the suction cups 15 at the same time, without having to release them one by one.

[0041] A groove 26 is horizontally formed on the upper surface of the fixed plate 3. A telescopic rod 27 is slidably installed in the groove 26. A cleaning plate 29 is fixedly installed at the top of the telescopic rod 27 via a connecting rod 28. Multiple water tanks 30 are formed on the upper surface of the cleaning plate 29. Cleaning fluid is contained in the water tanks 30. A piston plate 31 is slidably and sealed in the water tanks 30. A water inlet 32 ​​connecting to the outside is formed at the bottom of the water tanks 30. Straight rods 33 are fixedly installed on the upper surface of the piston plate 31. Rectangular plates 34 are fixedly installed at the top of the multiple straight rods 33. A mounting plate is fixedly installed on the side wall of the cleaning plate 29. Multiple second spring rods 35 are fixedly installed on the upper surface of the mounting plate. The tops of the multiple second spring rods 35 are all fixedly connected to the lower surface of the rectangular plate 34.

[0042] The piston plate 31 has a water inlet on its surface and a cover inside the water inlet. The cover can be opened to add cleaning fluid into the water tank 30. The water inlet 32 ​​is equipped with a pressure check valve, which is directed from inside the water tank 30 to the outside.

[0043] Once the shear plate is fixed, the lower surface of the cleaning plate 29 will contact the upper surface of the shear plate. Then, the cleaning plate 29 is controlled to move laterally back and forth, so that the cleaning plate 29 removes dust or impurities from the surface of the shear plate, thus preventing dust or impurities from affecting the quality of the joint welding.

[0044] Meanwhile, when the cleaning plate 29 moves laterally back and forth, the rectangular plate 34 can be controlled to move downward. At this time, multiple second spring rods 35 will retract, and multiple piston plates 31 will move downward in multiple water tanks 30 respectively. The space between the lower surface of the piston plate 31 and the bottom of the water tank 30 will become smaller, and the pressure will increase. The cleaning liquid in the water tank 30 will be discharged from the water outlet 32 ​​and act on the surface of the shear plate, which can improve the cleaning plate 29's effect of removing dust and impurities from the surface of the shear plate.

[0045] In this invention, the shear plate to be welded is first placed on the upper surface of the platform 1 and positioned between two first positioning plates 6. Then, one side of the shear plate is tightly pressed against the surface of the fixed plate 3, and the welding node of the shear plate is positioned at a suitable welding position. At this time, the first threaded rod 5 is rotated, and the first positioning plate 6 threaded onto the first threaded rod 5 will move laterally until both first positioning plates 6 are tightly pressed against the shear plate. Then, by rotating the second threaded rod 8, the second positioning plate 9 threaded onto the second threaded rod 8 will move laterally until both second positioning plates 9 are tightly pressed against the shear plate. At this time, the shear plate will be positioned in the auxiliary positioning space composed of the fixed plate 3, the two first positioning plates 6, and the two second positioning plates 9. No manual support is required, which improves the stability of the positioned shear plate and ensures the accuracy of the processed double shear plate node structure. It can also assist in the positioning of shear plates of different sizes, making it highly practical.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
