Description

Technical Field

[0001] The invention relates to the field of scaffold welding, and more particularly to a scaffold welding tool. Background Art

[0002] Scaffolding is a temporary construction facility erected at a construction site for workers to operate and solve vertical and horizontal transportation. Scaffolding is generally composed of components such as column frames, diagonal braces, and pedals. The column frames are welded together by multiple steel pipes. Due to the large demand for scaffolding in some projects, manual welding is inefficient and cannot meet production delivery dates when producing scaffolding. Therefore, automated welding is used in the existing technology to achieve automated welding of column frames. Automated welding requires welding tooling to fix multiple steel pipes to facilitate welding.

[0003] For example, the existing patent (publication number: CN111805157A) discloses an automatic welding tool for scaffolding columns, which connects multiple processes such as loading, welding and unloading to achieve automatic welding of scaffolding columns, thereby improving welding efficiency. Although automatic welding is achieved, impurities such as oil, rust, oxide scale, and dust may accumulate on the outer surface of steel pipes during transportation and storage. If these impurities are not treated before welding, they will affect the fusion quality of the weld and easily lead to slag inclusions, pores, and cracks during welding, thereby reducing the welding efficiency. To ensure the bearing capacity and durability of the overall structure, the outer surface of the steel pipe is usually processed manually with an angle grinder before welding. 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 moving range of the angle grinder. 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 the grinding process. If the steel pipe is not fixed on the tooling and then ground, the specific welding position of the welded pipe cannot be determined, so the outer surface of the steel pipe needs to be processed as a whole, resulting in low processing efficiency. Summary of the Invention

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] See also Figures 1 to 12 A scaffold welding tool comprises a base plate 1, a plurality of slots 11 provided inside the base plate 1, and a plurality of positioning members fixed to the upper end of the base plate 1 for positioning the workpiece, wherein the positioning members comprise an end limit plate 2 fixed to the upper end of the base plate 1, a pad 3, a clamping portion 4 and a side positioning portion 5.

[0038] A plurality of pipe material welding area processing units 6 are respectively connected to the plurality of slots 11, and the pipe material welding area processing units 6 include a slide 61 slidingly connected to the inner wall of the slide groove 643, a base body 62 fixed to the upper end of the slide 61, a cavity 63 opened inside the base body 62, a surface treatment component 64 slidingly connected to the inside of the cavity 63, and a cylinder 641 fixed to one side of the base body 62, and the telescopic end of the cylinder 641 passes through the base body 62 and is connected to the surface treatment component 64. The substrate 1 is also connected to a plurality of drive units 7 for driving the plurality of pipe material welding area processing units 6 to move;

[0039] The surface treatment component 64 includes a movable seat 642 slidingly connected to the inner wall of the cavity 63, two groups of elastic displacement components 10 connected to the inner wall of the movable seat 642, two groups of side plates 647 respectively rotatably connected to the two groups of elastic displacement components, two rollers 648 respectively rotatably connected to the two groups of side plates 647, and a sanding belt 649 sleeved on the outside of the two rollers 648.

[0040] The elastic displacement component 10 includes two groups of sliding grooves 643 symmetrically opened on the inner wall of the movable seat 642, a guide column 644 fixed on the inner wall of the sliding groove 643, a slider 646 sliding in the sliding groove 643 and movably sleeved on the outside of the guide column 644, and a spring 645 sleeved on the outside of the guide column 644, and the two ends of the spring 645 are respectively connected to the inner wall of the sliding groove 643 and the slider 646, one side of the side plate 647 is rotatably connected to the adjacent roller body 648, and the other side of the side plate 647 is rotatably connected to the adjacent slider 646.

[0041] The driving unit 7 includes a screw rod 72 rotatably connected to the inside of the base plate 1, and multiple motor driving parts 71 respectively fixed to the lower end and one side of the base plate 1, and the output shaft of the motor driving part 71 is transmission-connected to one end of the screw rod 72, and the slide seat 61 in the slot 11 is screwed to the outside of the screw rod 72.

[0042] By adopting the above technical solution, multiple steel pipes are placed on the pad 3 on one side of the base plate 1, wherein one end of two horizontally placed steel pipes contacts the end limit plate 2, and the two horizontally placed steel pipes are limited by the end limit plate 2, and the pressing part 4 (using the cylinder to drive the pressure block to press down) is lowered and the steel pipe is pressed, and the side positioning part 5 (using the cylinder to extend and drive the push rod to move toward the steel pipe) is used to clamp the steel pipe. The cylinder 641 is controlled to extend and push the movable seat 642 to move toward the steel pipe, and the sanding belt 649 contacts the outer surface of the steel pipe. At the same time, the outer surface of the steel pipe is arc-shaped. The cylinder 641 pushes the sanding belt 649 to move toward the steel pipe, which changes the shape of the sanding belt 649 from a plane to an arc surface. When the shape of the sanding belt 649 changes, the distance between the two ends of the sanding belt 649 will change, and the sanding belt 649 drives the roller 648 to move. The roller 648 The slider 646 is driven to move by the side plate 647, and the slider 646 slides in the slide groove 643 toward the direction of the spring 645, applying pressure to the spring 645 to compress the spring 645, and controlling the motor drive unit 71 to work. The motor drive unit 71 drives the screw rod 72 to rotate, and the rotation of the screw rod 72 drives the slide 61 to move in the slot 11. The movement of the slide 61 drives the seat body 62 to move, and the sanding 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 welding area on one side of the outer surface of the steel pipe can be automatically ground. This solves the problem of the tooling limiting the operating angle or moving range of the angle grinder during manual grinding, and can also 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 processing of the outer surface of the steel pipe.

[0043] like Figure 4 and Figure 9 As shown, the interiors of the plurality of said base bodies 62 are all connected to a pretreatment assembly 65, and the pretreatment assembly 65 includes an arcuate groove 653 provided on one side of the base body 62, an arcuate base 654 slidably connected in the arcuate groove 653, a brush head 656 fixed on one side of the arcuate base 654, a worm gear key 655 provided on one side of the arcuate base 654, and an adjusting worm 652 rotatably connected to the interior of the base body 62 and in transmission contact with the worm gear key 655. A motor 651 is fixed to the upper end of the base body 62, and the output shaft of the motor 651 is fixed to one end of the adjusting worm 652.

[0044] A scraper 67 and a scraper 66 are installed on one side of each of the base bodies 62, and the outer surface of the scraper 67 is wrapped with a fabric layer. The scraper 66 is located between the brush head 656 and the sanding belt 649.

[0045] An exhaust port 69 is formed inside each of the plurality of base bodies 62 , and a pipe interface 68 connected to the exhaust port 69 is fixedly connected to the upper end of the base body 62 .

[0046] By adopting the above technical solution, when the seat body 62 moves, the brush head 656 moves horizontally in contact with the outer surface of the steel pipe, and the outer surface of the steel pipe can be roughened and polished by the brush head 656 (a wire brush head can be selected). The motor 651 drives the adjusting worm 652 to rotate, and the rotation of the adjusting worm 652 can drive the arc seat 654 to move in the arc groove 653 through the worm gear key 655. The movement of the arc seat 654 in the arc groove 653 can drive the brush head 656 to move circumferentially. The circumferential movement of the brush head 656 in contact with the outer surface of the steel pipe can enhance the polishing effect, and the steel can be polished by the brush head 656. The welding area on the outer surface of the pipe is roughened to quickly deal with large-area rust, and then fine-treated with the sanding belt 649. The surface cleanliness after the two-step treatment is higher, and defects such as welding pores and slag inclusions are reduced. The scraper 66 can be used to scrape the material on the outer surface of the steel pipe that is brushed off by the brush head 656. The pipe interface 68 is connected to the air pipe. The gas enters from the pipe interface 68 and is discharged from the exhaust port 69, which can blow away the material on the outer surface of the steel pipe and on the scraper 66. The brush head 656 and the scraper 66 can remove the material on the outer surface of the steel pipe, reduce the wear of the sanding belt 649, and reduce the cost of consumables.

[0047] like Figure 4 、 Figure 7 and Figure 8 As shown, a shift assembly 10 is connected to one of the side plates 647 in the surface treatment assembly 64, and the shift assembly 10 includes two synchronous wheels 102 rotatably connected to the inside of the side plate 647, a synchronous belt 103 connecting the two synchronous wheels 102, and a motor three 101 fixed to one side of the side plate 647, and the output shaft of the motor three 101 is fixed to one of the synchronous wheels 102, and the other synchronous wheel 102 is fixed to one end of one of the roller bodies 648.

[0048] 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 follows: Figure 7 As shown, at this time, the motor 3 101 drives the synchronous wheel 102 to rotate, and the synchronous wheel 102 drives another synchronous wheel 102 and one of the rollers 648 to rotate through the synchronous belt 103. The rotation of the roller 648 drives the sanding belt 649 to move, which can change the contact position of the sanding belt 649 with the outer surface of the steel pipe, so that different areas of the sanding belt 649 contact the surface of the steel pipe in turn, preventing the sanding belt 649 from repeatedly grinding at the same position, reducing surface scratches or local over-grinding, and extending the service life of the sanding belt 649.

[0049] like Figure 1 、 Figure 2 、 Figure 10-12As shown, the upper end of the substrate 1 is connected to an end processing component 8, and the end processing component 8 includes a fixed seat 81 fixed to the upper end of the substrate 1, a slot 82 opened inside the fixed seat 81, a gear 1 83 rotatably connected to the inside of the fixed seat 81 and a gear 2 84 meshing with the gear 1 83, a brush head 2 85 fixed to the inner wall of the gear 2 84, a back plate 89 fixed to one side of the fixed seat 81, a through groove 891 opened inside the back plate 89, a motor 2 86 fixed to one side of the back plate 89, an exhaust port 2 87 opened inside the fixed seat 81, a pipe interface 2 88 fixed to the upper end of the fixed seat 81 and connected to the exhaust port 2 87, and the output shaft of the motor 2 86 passes through the back plate 89 and is fixed to the gear 1 83, and the air outlet end of the exhaust port 2 87 faces the brush head 2 85.

[0050] By adopting the above technical solution, Figure 2 The two ends of several steel pipes need to be contact-welded with the outer surfaces of adjacent steel pipes. The outer surfaces of the adjacent steel pipes can be pre-welded by the pipe material welding zone processing unit 6. The surface quality of the outer surfaces of the two ends of the steel pipe is also the key to the welding quality. Before fixing the steel pipe on the substrate 1, one end of the steel pipe can be inserted into the fixing seat 81 from the slot 82, and one end of the steel pipe is inserted into the hollow inner cavity of the gear 2 84. The motor 2 86 drives the gear 1 83 to rotate, and the rotation of the gear 1 83 drives the gear 2 84 to rotate. When the gear 2 84 rotates, it drives the brush head 2 85 (wire brush) to rotate and The outer surface of one end of the steel pipe is polished to remove rust, oxide scale, dust and other impurities in the welding area of the outer surface of one end of the steel pipe. The pipe interface 88 is connected to the air pipe. The gas enters the pipe interface 88 and is discharged from the exhaust port 87 to the brush head 85, which can blow away the impurities on the brush head 85. The blown impurities can be discharged from the through groove 891. The outer surfaces of both ends of the steel pipe are processed through the end processing component 8, which is beneficial to the adhesion of the welding pool and the metallurgical bonding between the metals, thereby forming a uniform and firm weld, making the welding between the two ends of the steel pipe and the outer surface of the adjacent steel pipe more stable and reliable.

[0051] like Figure 1 and Figure 3 As shown, a plurality of welding reinforcement components 9 are connected to the upper end of the substrate 1, and the welding reinforcement component 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 flip driving part 93 fixedly connected to one side of one of the vertical plates 91, and the output shaft of the flip driving part 93 is connected to the top plate 92.

[0052] By adopting the above technical solution, before the welding robot arm performs welding and after the welding robot arm completes welding of the steel pipe, the top plate 92 can be driven to flip by the flip driving 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 is flipped and moved to the vicinity of the welding area, and the welding area of the steel pipe is induction heated by the induction heating part 94. Induction heating is a mature existing technology and will not be described in detail 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 residual stress. The preheating and slow cooling treatments can significantly improve the mechanical properties, fatigue resistance and corrosion resistance of the welded joint.

[0053] Usage method: Place multiple steel pipes on the pad 3 on one side of the base plate 1, wherein one end of two horizontally placed steel pipes contacts the end limit plate 2, and the two horizontally placed steel pipes are limited by the end limit plate 2, and the pressing part 4 is lowered and pressed to tighten the steel pipe, and the side positioning part 5 is used to press and limit the side of the steel pipe, and then control the cylinder 641 to work and extend and push the movable seat 642 to move toward the steel pipe, and the sanding belt 649 contacts the outer surface of the steel pipe, and the outer surface of the steel pipe is arc-shaped. The cylinder 641 pushes the sanding belt 649 to move toward the steel pipe, which changes the shape of the sanding belt 649 from a plane to an arc surface. When the shape of the sanding belt 649 is generated When the change occurs, the distance between the two ends of the sanding belt 649 will change, and the sanding 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, and the slider 646 slides in the direction of the spring 645 in the slide groove 643, and pressurizes the spring 645 to compress the spring 645, and controls the motor drive unit 71 to work, and drives the screw rod 72 to rotate through the motor drive unit 71, and the rotation of the screw rod 72 drives the slide 61 to move in the slot 11, and the movement of the slide 61 drives the seat body 62 to move, and the sanding 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.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
