Description

Technical Field

[0001] The present invention relates to the field of scaffold welding, and more specifically, to a scaffold welding tooling. Background Art

[0002] A scaffold is a temporary construction facility erected at a building construction site for workers to operate and solve vertical and horizontal transportation problems. A scaffold generally consists of components such as upright frames, diagonal braces, and pedals. The upright frame is composed of multiple steel pipes welded together. Due to the large demand for scaffolds in some projects, when producing scaffolds, the efficiency of manual welding is low and cannot meet the production delivery date. Therefore, in the prior art, an automated welding method is adopted to achieve the automated welding of the upright frame, and a welding tooling is required to fix multiple steel pipes for convenient welding.

[0003] For example, the existing patent (Publication No.: CN111805157A) discloses an automatic welding tooling for scaffold uprights, which connects multiple processes such as loading, welding, and unloading to achieve the automatic welding of scaffold uprights and improve the welding efficiency. Although automated welding is achieved, during the transportation and storage of steel pipes, impurities such as oil stains, rust, scale, and dust may accumulate on their outer surfaces. If not treated before welding, these impurities will affect the fusion quality of the weld seam, easily cause slag inclusions, pores, and cracks during the welding process, thereby reducing the load-bearing capacity and durability of the overall structure. Before welding, the outer surface of the steel pipe is usually manually treated with a grinding machine. If the steel pipe is fixed on the tooling and then the welding area is specifically ground, the tooling may limit the operating angle or movement range of the grinding machine. For example, in a narrow space or a tooling with a complex shape, it is difficult to flexibly adjust the grinding direction, which is not conducive to grinding. If the steel pipe is not fixed on the tooling for grinding treatment, the specific welding position of the welded pipe cannot be determined, so the outer surface of the steel pipe needs to be treated as a whole, resulting in low treatment efficiency. Summary of the Invention

[0004] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a scaffold welding tooling.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0010] Furthermore, a displacement component is connected inside one of the side plates of the surface treatment component, and the displacement component includes two synchronous wheels rotatably connected inside the side plate, a synchronous belt connecting the two synchronous wheels, and a third motor fixedly connected to one side of the side plate, and the output shaft of the third motor is fixedly connected to one of the synchronous wheels, and the other synchronous wheel is fixedly connected to one end of one of the rollers.

[0011] Furthermore, a scraper and a scraping knife are installed on one side of each of the plurality of seat bodies, and the outer surface of the scraper is wrapped with a fabric layer, and the scraping knife is located between the first brush head and the sand belt.

[0012] Furthermore, a first exhaust port is opened inside each of the plurality of seat bodies, and a pipe interface one connected to the first exhaust port is fixedly connected to the upper end of the seat body.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this solution, a pipe material welding area processing unit is provided.

At the same time, the coarsening treatment can remove large rust blocks, reduce the wear of the sand belt, and reduce the consumable cost. Then, the displacement component drives the sand belt to move, changing the position where the sand belt contacts the outer surface of the steel pipe, so that different areas of the sand belt take turns to contact the surface of the steel pipe, preventing the sand belt from repeatedly grinding at the same position, reducing surface scratches or local over-grinding, and prolonging the service life of the sand belt.

[0018] (3) This solution is provided with an end treatment component. Through the end treatment component, the outer surface of the steel pipe end can be quickly polished, removing the scale, oil stain, rust and burrs on the outer surface of the steel pipe end. The surface of the steel pipe becomes rougher, which is beneficial to the adhesion of the welding molten pool and the metallurgical bonding between metals, thus forming a uniform and firm weld seam, making the welding joints between the two ends of the steel pipe and the outer surface of the adjacent steel pipe more stable and reliable.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 12 , a scaffolding welding tooling, including a substrate 1, a plurality of grooves 11 opened inside the substrate 1, and a plurality of positioning parts fixed on the upper end of the substrate 1 for positioning workpieces. The positioning parts include an end limiting plate 2, a pad seat 3, a compression part 4 and a side positioning part 5 fixed on the upper end of the substrate 1.

[0023] A plurality of pipe material welding area processing units 6 are respectively connected in the plurality of grooves 11. The pipe material welding area processing unit 6 includes a slide seat 61 slidably connected to the inner wall of the slide groove 643, a seat body 62 fixed on the upper end of the slide seat 61, a cavity 63 opened inside the seat body 62, a surface treatment component 64 slidably connected inside the cavity 63, and a cylinder 641 fixed on one side of the seat body 62. The telescopic end of the cylinder 641 penetrates through the seat body 62 and is connected to the surface treatment component 64. A plurality of driving units 7 for driving the plurality of pipe material welding area processing units 6 to move are also connected inside the substrate 1; The surface treatment assembly 64 includes a movable seat 642 slidably connected to the inner wall of the cavity 63, two sets of elastic displacement components 10 connected to the inner wall of the movable seat 642, two sets of side plates 647 rotatably connected to the two sets of elastic displacement components respectively, two rollers 648 rotatably connected to the two sets of side plates 647 respectively, and a sand belt 649 sleeved outside the two rollers 648.

[0024] The elastic displacement component 10 includes two sets of chutes 643 symmetrically formed on the inner wall of the movable seat 642, guide posts 644 fixed to the inner walls of the chutes 643, sliders 646 slidably connected in the chutes 643 and movably sleeved outside the guide posts 644, and springs 645 sleeved outside the guide posts 644. Both ends of the spring 645 are connected to the inner wall of the chute 643 and the slider 646 respectively. One side of the side plate 647 is rotatably connected to the adjacent roller 648, and the other side of the side plate 647 is rotatably connected to the adjacent slider 646.

[0025] The driving unit 7 includes a lead screw 72 rotatably connected inside the substrate 1, and a plurality of motor driving parts 71 fixed to the lower end and one side of the substrate 1 respectively. The output shaft of the motor driving part 71 is in transmission connection with one end of the lead screw 72. The sliding seat 61 in the slot 11 is screwed outside the lead screw 72.

[0026] By adopting the above technical solution, multiple steel pipes are placed on the pedestal 3 on one side of the base plate 1. One end of two horizontally placed steel pipes contacts the end limiting plate 2, and the two horizontally placed steel pipes are limited by the end limiting plate 2. The pressing part 4 (by means of a cylinder driving a pressing block to press down) descends and presses the steel pipes. The side positioning part 5 (by means of a cylinder extending and driving a push rod to move towards the steel pipe) presses and limits the steel pipes on the side. Then, the cylinder 641 is controlled to work and extend to push the movable seat 642 to move towards the steel pipe. The abrasive belt 649 contacts the outer surface of the steel pipe. At the same time, the outer surface of the steel pipe is arc-shaped. When the cylinder 641 pushes the abrasive belt 649 to move towards the steel pipe, the shape of the abrasive belt 649 changes from a plane to an arc surface. When the shape of the abrasive belt 649 changes, the distance between the two ends of the abrasive belt 649 changes. The abrasive belt 649 drives the roller body 648 to move, and the roller body 648 drives the slider 646 to move through the side plate 647. The slider 646 slides in the chute 643 towards the direction of the spring 645, pressing the spring 645 to compress it. The motor driving part 71 is controlled to work. By the work of the motor driving part 71, the lead screw 72 rotates. The rotation of the lead screw 72 drives the sliding seat 61 to move in the slotted opening 11. The movement of the sliding seat 61 drives the seat body 62 to move. The abrasive belt 649 moves on the outer surface of the steel pipe and grinds the welding area on one side of the outer surface of the steel pipe. After the steel pipe is placed on the base plate 1 and positioned, the automatic grinding treatment of the welding area on one side of the outer surface of the steel pipe can be realized. It not only solves the problem that the operation angle or moving range of the angle grinder is restricted by the tooling during manual grinding, but also can perform targeted grinding on the welding area of the steel pipe, shortening the grinding time and avoiding the low processing efficiency caused by the overall treatment of the outer surface of the steel pipe.

[0027] As Figure 4 and Figure 9 shown, a pretreatment assembly 65 is connected inside each of the plurality of seat bodies 62. The pretreatment assembly 65 includes an arc-shaped groove 653 opened on one side of the seat body 62, an arc-shaped seat 654 slidably connected in the arc-shaped groove 653, a first brush head 656 fixedly connected to one side of the arc-shaped seat 654, a worm gear tooth key 655 opened on one side of the arc-shaped seat 654, and an adjusting worm 652 rotatably connected inside the seat body 62 and in transmission contact with the worm gear tooth key 655. A first motor 651 is fixedly connected to the upper end of the seat body 62, and an output shaft of the first motor 651 is fixedly connected to one end of the adjusting worm 652.

[0028] A scraper 67 and a scraper knife 66 are installed on one side of each of the plurality of seat bodies 62. A fabric layer is wrapped on the outer surface of the scraper 67. The scraper knife 66 is located between the first brush head 656 and the abrasive belt 649.

[0029] An exhaust port 69 is opened inside each of the plurality of seat bodies 62, and a pipe interface 68 communicated with the exhaust port 69 is fixedly connected to the upper end of the seat body 62.

[0030] By adopting the above technical solution, when the seat body 62 moves, the first brush head 656 moves horizontally in contact with the outer surface of the steel pipe. Through the first brush head 656 (a wire brush head can be selected), the outer surface of the steel pipe can be coarsely polished. The first motor 651 works to drive the adjusting worm 652 to rotate. The rotation of the adjusting worm 652 can drive the arc-shaped seat 654 to move in the arc-shaped groove 653 through the worm gear key 655. The movement of the arc-shaped seat 654 in the arc-shaped groove 653 can drive the first brush head 656 to move circumferentially. The circumferential movement contact between the first brush head 656 and the outer surface of the steel pipe can enhance the polishing effect. Through the first brush head 656, the welded area on the outer surface of the steel pipe can be coarsely processed, quickly treating large-area rust. Then, fine processing is carried out through the sand belt 649. The surface cleanliness after the two-step treatment is higher, reducing defects such as welding pores and slag inclusions. Through the scraper 66, the substances brushed off the outer surface of the steel pipe by the first brush head 656 can be scraped. The first pipeline interface 68 is externally connected to an air pipe. Gas enters from the first pipeline interface 68 and is discharged from the first exhaust port 69, which can blow off the substances on the outer surface of the steel pipe and on the scraper 66. Through the first brush head 656 and the scraper 66, the substances on the outer surface of the steel pipe can be removed, reducing the wear of the sand belt 649 and lowering the consumable cost.

[0031] As Figure 4 、 Figure 7 and Figure 8 shown, one of the side plates 647 in the surface treatment assembly 64 is internally connected with a displacement assembly 10. The displacement assembly 10 includes two synchronous pulleys 102 rotatably connected inside the side plate 647, a synchronous belt 103 connecting the two synchronous pulleys 102, and a third motor 101 fixed on one side of the side plate 647. The output shaft of the third motor 101 is fixedly connected to one of the synchronous pulleys 102, and the other synchronous pulley 102 is fixedly connected to one end of one of the rollers 648.

[0032] By adopting the above technical solution, when the sand belt 649 is separated from the outer surface of the steel pipe, the state of the sand belt 649 is as Figure 7 shown. At this time, the third motor 101 works to drive the synchronous pulley 102 to rotate. The synchronous pulley 102 drives the other synchronous pulley 102 and one of the rollers 648 to rotate through the synchronous belt 103. The rotation of the roller 648 drives the sand belt 649 to move, which can change the position where the sand belt 649 contacts the outer surface of the steel pipe, so that different areas of the sand belt 649 take turns to contact the steel pipe surface, preventing the sand belt 649 from repeatedly polishing at the same position, reducing surface scratches or local over-polishing, and prolonging the service life of the sand belt 649.

[0033] As Figure 1 、 Figure 2 、 Figures 10 - 12As shown in the figure, an end processing assembly 8 is connected to the upper end of the substrate 1. The end processing assembly 8 includes a fixed seat 81 fixedly connected to the upper end of the substrate 1, a slot 82 opened inside the fixed seat 81, a first gear 83 rotatably connected inside the fixed seat 81, a second gear 84 meshing with the first gear 83, a second brush head 85 fixedly connected to the inner wall of the second gear 84, a back plate 89 fixedly connected to one side of the fixed seat 81, a through groove 891 opened inside the back plate 89, a second motor 86 fixedly connected to one side of the back plate 89, an exhaust port two 87 opened inside the fixed seat 81, and a pipe interface two 88 fixedly connected to one upper end of the fixed seat 81 and communicating with the exhaust port two 87. The output shaft of the second motor 86 passes through the back plate 89 and is fixedly connected to the first gear 83. The air outlet end of the exhaust port two 87 faces the second brush head 85.

[0034] By adopting the above technical solutions, Figure 2 There are several steel pipes whose two ends need to be in contact welding with the outer surfaces of adjacent steel pipes. The outer surfaces of adjacent steel pipes can be pre-treated before welding through the pipe material welding area processing unit 6. The surface quality of the outer surfaces of the two ends of the steel pipes is also the key to affecting the welding quality. Before fixing the steel pipe on the substrate 1, one end of the steel pipe can be inserted into the fixed seat 81 from the slot 82 first. One end of the steel pipe is inserted into the hollow inner cavity of the second gear 84. When the second motor 86 works, it drives the first gear 83 to rotate. The rotation of the first gear 83 drives the second gear 84 to rotate. When the second gear 84 rotates, it drives the second brush head 85 (steel wire brush) to rotate and polish the outer surface of one end of the steel pipe, removing impurities such as rust, oxide scale, and dust from the welding area on the outer surface of one end of the steel pipe. The pipe interface two 88 is externally connected to an air pipe. Gas enters the pipe interface two 88 and is discharged from the exhaust port two 87 and blows towards the second brush head 85, which can blow away the impurities on the second brush head 85. The blown-away impurities can be discharged from the through groove 891. Through the end processing assembly 8, the outer surfaces of the two ends of the steel pipe are processed, which is beneficial to the attachment of the welding molten pool and the metallurgical combination between metals, thereby forming a uniform and firm weld seam, making the welding joints between the two ends of the steel pipe and the outer surfaces of adjacent steel pipes more stable and reliable.

[0035] As Figure 1 and Figure 3 shown in the figure, a plurality of welding strengthening assemblies 9 are connected to the upper end of the substrate 1. The welding strengthening assembly 9 includes two vertical plates 91 fixedly connected to the upper end of the substrate 1, a top plate 92 rotatably connected between the two vertical plates 91, two induction heating parts 94 fixedly connected to one side of the top plate 92, and a flipping driving part 93 fixedly connected to one side of one of the vertical plates 91. The output shaft of the flipping driving part 93 is connected to the top plate 92.

[0036] By adopting the above technical solution, before the welding robot performs the welding operation and after the welding robot finishes welding the steel pipe, the top plate 92 can be driven to flip by the flipping drive part 93. When the top plate 92 rotates, it can drive the induction heating part 94 to move, so that the induction heating part 94 flips and moves to the vicinity of the welding area. The welding area of the steel pipe is induction heated by the induction heating part 94. Induction heating belongs to the mature existing technology and will not be elaborated here. The steel pipe before welding is preheated by induction heating to reduce the risk of cold cracks. The steel pipe after welding is slowly cooled by induction heating, which can make the metal shrink evenly and reduce the residual stress. Through the treatment of preheating and slow cooling, the mechanical properties, fatigue resistance and corrosion resistance of the welded joint can be significantly improved.

[0037] Usage method: Place multiple steel pipes on the cushion block 3 on one side of the base plate 1. One end of two horizontally placed steel pipes contacts the end limiting plate 2. The two horizontally placed steel pipes are limited by the end limiting plate 2. The pressing part 4 descends and presses the steel pipes. The steel pipes are laterally pressed and limited by the side positioning part 5. Then, control the cylinder 641 to work and extend, and push the movable seat 642 to move towards the steel pipe. The abrasive belt 649 contacts the outer surface of the steel pipe. At the same time, the outer surface of the steel pipe is arc-shaped. When the cylinder 641 pushes the abrasive belt 649 to move towards the steel pipe, the shape of the abrasive belt 649 will change from a plane to an arc surface. When the shape of the abrasive belt 649 changes, the distance between the two ends of the abrasive belt 649 will change. The abrasive belt 649 drives the roller body 648 to move. The roller body 648 drives the slider 646 to move through the side plate 647. The slider 646 slides in the chute 643 towards the direction of the spring 645, pressing the spring 645 to compress it. Control the motor drive part 71 to work. The motor drive part 71 drives the lead screw 72 to rotate when it works. The rotation of the lead screw 72 drives the slide seat 61 to move in the slotted opening 11. The movement of the slide seat 61 drives the seat body 62 to move. The abrasive belt 649 moves on the outer surface of the steel pipe and grinds the welding area on one side of the outer surface of the steel pipe.

[0038] The above is only the preferred specific implementation manner of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
