Description

Technical Field

[0001] The invention belongs to the technical field of building steel structure node welding equipment, in particular to a building steel structure node welding equipment. Background Art

[0002] In steel structure buildings, hollow node balls are used for connection at multiple steel structure nodes. They connect multiple steel structures together through a spherical structure to form a whole to transmit and distribute the force between the steel structures, ensuring the stability and safety of the structure. When welding hollow ball nodes, two round steel plates need to be hot-pressed or cold-pressed into semi-spherical shells, and then the two semi-spherical shells are butt-jointed and welded into a whole using arc welding.

[0003] A patent with announcement number CN118371955B discloses a method for welding nodes of building steel structures, which includes a workbench, a driving motor drives the active sprocket to rotate, so that the corresponding roller rotates, and cooperates with the clamping device to drive the welding ball placed on the two support plates to rotate for welding. At the same time, when the welding ball rotates the first circle, the operator performs positioning welding on the weld, and at the same time, the brushing device brushes anti-splash material on both sides of the weld. During the second circle, the brushing device automatically stops brushing the weld, and the operator can perform full welding on the weld, which speeds up the production rhythm and improves welding efficiency.

[0004] When welding the node balls, the above scheme does not improve the clamping and fixing of the node balls, and still uses traditional clamping equipment such as threaded rotation to fix the node balls on the fixing equipment. The angles and positions of the two node balls are then adjusted by the clamping equipment to make the welding point vertical or horizontal for more convenient welding. Not only does it cause the problem of time-consuming and labor-intensive fixing of the node balls, but it also causes deviations in the fixing position and angle of the node balls, resulting in deviations in the weld seams of the welded node balls, which reduces the efficiency of welding the node balls and deteriorates the welding effect.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1: Figures 1 to 9As shown, a building steel structure node welding device according to an embodiment of the present invention includes a welding table 1, two fixing devices are provided on one side of the welding table 1, and the two fixing devices are arranged opposite to each other. The fixing device includes a sliding disk 28 slidably connected to one side of the welding table 1, and a plurality of connection frames 31 are slidably connected to one side of the sliding disk 28. Magnetic balls 32 are rotatably arranged in the plurality of connection frames 31, and the plurality of magnetic balls 32 are used to fix the hemispheres 12. A first motor 2 is fixedly connected to one side of the welding table 1, and a driving gear 3 is fixedly connected to the output end of the first motor 2. Two transmission rods 7 are rotatably connected to one side of the welding table 1, and the two transmission rods 7 are rotatably connected to the two transmission rods 7. The moving rod 7 is fixed with a driven gear 5 at one end close to the first motor 2, a chain 4 is meshed between the two driven gears 5, the driving gear 3 is meshed with the chain 4, the two hemispheres 12 are placed on the two transmission rods 7, a sliding cylinder 14 is slidably connected to one side of the welding table 1, a welding head 15 is slidably connected in the sliding cylinder 14, a coating device is provided on the other side of the welding table 1, the coating device includes a first slide 17, one end of the first slide 17 is rotatably connected to two rollers 47, a liquid inlet pipe 48 is provided in the first slide 17, and the coating device is used to apply anti-splash coating to the welding point of the two hemispheres 12.

[0033] Specifically, at present, when welding node balls, workers need to fix the two halves of the node balls by tightening the fixing equipment with bolts, and adjust the angle and position of the two node balls so that the welding point is vertical or horizontal for easier welding. Then, the node balls are preliminarily spot-welded to fix them by arc welding with electrodes, and then anti-splash paint is applied near the welding point of the node balls to prevent welding slag from adhering to the weld seam, thereby reducing the subsequent processing workload near the weld seam. Then, the two halves of the node balls are fully welded to complete the welding of the node balls. The workers fix half of the node balls on the fixing equipment and manually adjust the angle and position of the node balls. Not only does it take time and effort to fix the node balls, but it also causes deviations in the fixing position and angle of the node balls, resulting in deviations in the weld seam of the welded node balls, which reduces the efficiency of welding the node balls and deteriorates the welding effect.

[0034] In this embodiment, when welding the node ball, the hemisphere 12 is placed on the magnetic ball 32 in the fixing device, and the hemisphere 12 is adsorbed and fixed by multiple magnetic balls 32. The two sliding disks 28 are moved to move the magnetic balls 32 toward each other through multiple connecting frames 31. The magnetic balls 32 move the two hemispheres 12 toward each other and press against each other. When the two hemispheres 12 press against each other, the hemisphere 12 will rotate through the magnetic ball 32 so that the connection between the two hemispheres 12 is automatically in a vertical state for welding. The fixing device is moved up and down so that the two hemispheres 12 are placed on the transmission rod 7, the first motor 2 is started to rotate the driving gear 3 and the two driven gears 5 are rotated through the chain 4. The driven gear 5 rotates to rotate the transmission rod 7 and rotates the hemisphere 12. The welding head 15 is connected to the welding machine through the welding pipe and is used with a 316 stainless steel welding rod to perform arc welding on the two hemispheres 12. The 316 stainless steel welding rod is austenitic stainless steel, which is usually non-magnetic or weakly magnetic. The sliding cylinder 14 is moved and the welding head 15 is moved up and down. The welding head 15 is moved to one side of the hemisphere 12, and then the two hemispheres 12 are spot-welded with the welding rod to preliminarily fix the two hemispheres 12, and then the first slide 17 and the roller 47 are moved close to the contact point of the two hemispheres 12, and the paint is input into the roller 47 through the liquid inlet pipe 48, and the paint is applied to the weld of the hemisphere 12 through the roller 47, and the anti-splash paint is applied to the welding point of the two hemispheres 12 through the coating device to prevent welding slag and sparks from splashing. When the anti-splash paint is applied, the two hemispheres 12 are fully arc-welded to complete the welding of the node ball; the magnetic ball 32 of the fixing device adsorbs and fixes the hemisphere 12, which can be fixed more quickly for welding, without the operator manually fixing and adjusting the docking point of the hemisphere 12. When the fixing device is held against the hemisphere 12, the welding point of the two hemispheres 12 will automatically adjust to a vertical state for welding, reducing the fixing time of the node ball to speed up the welding efficiency of the node ball.

[0035] like Figure 2 As shown, both ends of the two transmission rods 7 are rotatably connected to the first sliders 6, and multiple first sliders 6 are slidably connected to the welding table 1. Both sides of the welding table 1 are rotatably connected to the bidirectional screw rods 8, and the two bidirectional screw rods 8 are threadedly connected to the two first sliders 6 on one side.

[0036] Specifically, when the chain 4 becomes loose after long-term transmission, the first sliders 6 on both sides are synchronously moved in opposite directions by rotating the bidirectional screw rod 8, so that the two transmission rods 7 move with the driven gear 5 to tighten the chain 4, so that the first motor 2 can better rotate the transmission rod 7 through the driving gear 3 and the chain 4.

[0037] like Figure 6 As shown, a spacer wheel 10 is fixed to one side of each of the two transmission rods 7. The two spacer wheels 10 are located between the two hemispheres 12 and are provided with a spacer ring. The two spacer wheels 10 are used to space the hemispheres 12 for welding.

[0038] Specifically, when the two hemispheres 12 abut against each other, the two hemispheres 12 will abut against both sides of the spacing wheel 10 to create a gap, so that there is a gap between the two hemispheres 12 for easy welding. The spacing wheel 10 can also better rotate the hemispheres 12 for welding.

[0039] like Figure 7 As shown, a partition plate 37 is fixed between the two hemispheres 12, and two telescopic devices are provided on one side of the partition plate 37. The telescopic devices include a partition frame 38 fixed to one side of the partition plate 37, and a telescopic plate 39 is slidably connected in the partition frame 38. A fixed rod 41 is fixed to one side of the partition frame 38, and a first spring 40 is sleeved on one side of the fixed rod 41. One end of the first spring 40 is fixed to the telescopic plate 39, and the other end of the first spring 40 is fixed to the partition frame 38.

[0040] Specifically, when welding a larger hemisphere 12, the telescopic plate 39 is pulled out of the dividing frame 38, so that the first spring 40 stretches and slides along the fixed rod 41, and the two hemispheres 12 can be spaced apart by the cooperation of the telescopic plate 39 and the spacing wheel 10. When the two hemispheres 12 move relative to each other, the two hemispheres 12 will rest on both sides of the telescopic plate 39 and the spacing wheel 10, so that the joint of the two hemispheres 12 can remain vertical and leave a gap, which is more convenient for welding the two hemispheres 12.

[0041] like Figure 7 As shown, a connecting frame 45 is fixedly connected to one side of the telescopic plate 39, a card slot 43 is opened on one side of the dividing frame 38, a card block 42 is rotatably connected to one side of the connecting frame 45, one side of the connecting frame 45 is fixed to one end of the second spring 44, the other end of the second spring 44 is fixed to the card block 42, and one end of the card block 42 is matched with the card slot 43.

[0042] Specifically, when spacing the two hemispheres 12 , press one side of the connecting frame 45 to rotate the card block 42 so that the card block 42 moves out of the card slot 43 , and the moving card block 42 slides out of the dividing frame 38 with the telescopic plate 39 , and the telescopic plate 39 can be extended to space the two hemispheres 12 .

[0043] like Figure 3 As shown, one side of the sliding disk 28 is rotatably connected to a connecting gear 29, and one side of the sliding disk 28 is rotatably connected to a toothed disk 30. The connecting gear 29 is meshed with the toothed disk 30. A plurality of arc grooves are provided on one side of the toothed disk 30. The toothed disk 30 is slidably connected to the connecting frame 31 through the arc grooves.

[0044] Specifically, when fixing the hemisphere 12, the connecting gear 29 is rotated to rotate the toothed disc 30, and the rotation of the toothed disc 30 causes the connecting frame 31 to slide in the limiting groove 33, so that the connecting frame 31 can slide and expand through the arc groove in the toothed disc 30, and the hemisphere 12 can be fixed by adjusting the size by moving the magnetic ball 32 with multiple connecting frames 31.

[0045] like Figure 4As shown, an adjusting device is provided on both sides of the welding table 1, and the adjusting device includes a second motor 18 fixedly connected to one side of the welding table 1, and a fixed plate 9 is fixedly connected to both sides of the welding table 1. A lifting plate 19 is slidably connected to one side of the fixed plate 9, and a first threaded rod 21 is fixedly connected to the output end of the second motor 18. The first threaded rod 21 is threadedly connected to the lifting plate 19, and a second slide plate 25 is slidably connected inside the lifting plate 19. A third slide plate 34 is slidably connected to the outer side of the sliding disk 28, and the sliding disk 28 is fixed to the second slide plate 25.

[0046] Specifically, when the fixing device is moved, the second motor 18 is started to rotate the first threaded rod 21 to move the lifting plate 19 on the fixing plate 9. The lifting plate 19 moves in the third slide 34 with the sliding disk 28 through the second slide 25, and can move the hemisphere 12 fixed on the fixing device up and down, adjust the height of the hemisphere 12, and place the hemisphere 12 on the transmission rod 7 for welding.

[0047] like Figure 5 As shown, the adjusting device also includes a third motor 26 fixedly connected to one side of the lifting plate 19, the output end of the third motor 26 is fixedly connected to a threaded cylinder 27, one side of the sliding disk 28 is fixedly connected to a sleeve 35, the threaded cylinder 27 is threadedly connected to the sleeve 35, and a connecting rod 36 is slidably connected in the threaded cylinder 27, and the connecting rod 36 is fixedly connected to the connecting gear 29.

[0048] Specifically, when the sliding disk 28 is moved to make the hemispheres 12 collide with each other, the third motor 26 is started to rotate the threaded barrel 27. The rotation of the threaded barrel 27 causes the sleeve 35 to push the sliding disk 28 with the third slide 34 to slide on the welding table 1, thereby pushing the two hemispheres 12 to collide with each other. The rotation of the threaded barrel 27 causes the connecting rod 36 to rotate and can slide in the threaded barrel 27, so that when the sliding disk 28 moves, the connecting rod 36 can slide out of the threaded barrel 27 and rotate with the connecting gear 29. The rotation of the connecting gear 29 causes the toothed disk 30 to rotate to adjust the distance between the multiple magnetic balls 32 to fix the hemispheres 12.

[0049] Example 2: Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0050] A lifting frame 24 is slidably connected between the two fixed plates 9. The coating device includes a connecting block 16 fixed to one side of the lifting frame 24. The connecting block 16 is slidably connected to the first slide 17. One end of the first slide 17 is located between the two rollers 47 and is fixed with a scraper block 46.

[0051] Specifically, after the hemisphere 12 is fixed, the lifting frame 24 is moved to move the connecting block 16 and the first slide 17, and then the first slide 17 is moved to slide on the connecting block 16 to adjust the distance between the scraping block 46 and the roller 47 and the hemisphere 12, so that the roller 47 can be pressed against the welding part of the hemisphere 12 to apply anti-splash paint, and the scraping block 46 is inserted into the gap to scrape off excess paint to prevent the paint from affecting the welding between the hemispheres 12.

[0052] like Figure 4 As shown, the adjusting device also includes a second threaded rod 13 rotatably connected to one side of the welding table 1, and a transmission wheel 23 is fixedly connected to one end of the second threaded rod 13 and the first threaded rod 21. The two transmission wheels 23 are connected by a transmission belt 11, and the lifting frame 24 is threadedly connected to the second threaded rod 13.

[0053] Specifically, when the roller 47 is adjusted to apply paint, the first threaded rod 21 rotates to rotate the transmission wheel 23, which is then transmitted through the transmission belt 11 to rotate the other transmission wheel 23, thereby rotating the second threaded rod 13 to cause the lifting frame 24 to slide on the two fixed plates 9 to adjust the height of the first slide plate 17, so that the roller 47 and the scraper 46 can better apply paint to 12.

[0054] Working principle: When welding the node ball, place the hemisphere 12 on the magnetic ball 32 in the fixing device, and fix the hemisphere 12 by adsorbing it through multiple magnetic balls 32. Move the two sliding disks 28 through multiple connecting frames 31 to make the magnetic balls 32 move toward each other. The magnetic balls 32 move the two hemispheres 12 toward each other and press against each other. When the two hemispheres 12 press against each other, the hemisphere 12 will rotate through the magnetic ball 32 so that the connection between the two hemispheres 12 will automatically be in a vertical state for welding. Move the fixing device up and down so that the two hemispheres 12 are placed on the transmission rod 7. Start the first motor 2 to rotate the driving gear 3 and rotate the two driven gears 5 through the chain 4. The driven gear 5 rotates to rotate the transmission rod 7 and rotates the hemisphere 12. The welding head 15 is connected to the welding machine through the welding pipe and is used with 316 stainless steel welding rods to perform arc welding on the two hemispheres 12. The 316 stainless steel welding rod is austenitic stainless steel, which is usually non-magnetic or weakly magnetic. The sliding cylinder 14 moves the welding head 15 up and down so that the welding head 15 moves to one side of the hemisphere 12, and then spot welds the two hemispheres 12 with the welding rod to preliminarily fix the two hemispheres 12, and then moves the first slide plate 17 and the roller 47 close to the contact point of the two hemispheres 12, inputs the coating into the roller 47 through the liquid inlet pipe 48, and applies the coating to the side of the weld of the hemisphere 12 through the roller 47, and applies anti-splash coating to the welding point of the two hemispheres 12 through the coating device to prevent welding slag and sparks from splashing. When the anti-splash coating is applied, the two hemispheres 12 are fully arc welded to complete the welding of the node balls; when the chain 4 is loosened after long-term transmission, the first sliders 6 on both sides are synchronously moved in the opposite direction by rotating the bidirectional screw rod 8, so that the two transmission rods 7 move with the driven gear 5 to tighten the chain 4, so that the first motor 2 can better rotate the transmission rod 7 through the driving gear 3 and the chain 4;

[0055] When the two hemispheres 12 are against each other, the two hemispheres 12 will be against the two sides of the spacing wheel 10 to produce a gap, so that there is a gap between the two hemispheres 12 for easy welding, and the spacing wheel 10 can also be used to better rotate the hemispheres 12 for welding; when welding larger hemispheres 12, the telescopic plate 39 is pulled out from the dividing frame 38, so that the first spring 40 is stretched and slid along the fixed rod 41, and the two hemispheres 12 can be spaced apart by the cooperation of the telescopic plate 39 and the spacing wheel 10. When the two hemispheres 12 move relative to each other, the two hemispheres 12 will be against the two sides of the telescopic plate 39 and the spacing wheel 10, so that the joint of the two hemispheres 12 can be maintained Maintaining a vertical state with a gap between them makes it easier to weld the two hemispheres 12. When spacing the two hemispheres 12, pressing one side of the connecting frame 45 rotates the clamping block 42 so that the clamping block 42 moves out of the clamping slot 43. The movable clamping block 42 slides out of the dividing frame 38 with the telescopic plate 39, and the telescopic plate 39 is extended to space the two hemispheres 12. When fixing the hemisphere 12, rotating the connecting gear 29 rotates the toothed disc 30. The rotation of the toothed disc 30 causes the connecting frame 31 to slide in the limiting groove 33, so that the connecting frame 31 can slide and expand through the arc groove in the toothed disc 30. The size of the fixed hemisphere 12 can be adjusted by moving the magnetic balls 32 with multiple connecting frames 31.

[0056] When the fixing device is moved, the second motor 18 is started to rotate the first threaded rod 21 and move the lifting plate 19 on the fixing plate 9. The lifting plate 19 moves in the third slide 34 with the sliding disk 28 through the second slide 25, and can move the hemisphere 12 fixed on the fixing device up and down, adjust the height of the hemisphere 12, and place the hemisphere 12 on the transmission rod 7 for welding; when the sliding disk 28 is moved to make the hemispheres 12 offset each other, the third motor 26 is started to rotate the threaded barrel 27, and the threaded barrel 27 rotates to make the sleeve 35 push the sliding disk 28 to slide on the welding table 1 with the third slide 34, and can push the two hemispheres 12 to offset each other. The threaded barrel 27 rotates to make the connecting rod 36 rotate and slide in the threaded barrel 27, so that when the sliding disk 28 moves, the connecting rod 36 can slide out of the threaded barrel 27 and rotate with the connecting gear 29, connecting The gear 29 rotates to rotate the toothed disc 30 to adjust the distance between the multiple magnetic balls 32 to fix the hemisphere 12; when the hemisphere 12 is fixed, the lifting frame 24 is moved to move the connecting block 16 and the first slide 17, and then the first slide 17 is moved to slide on the connecting block 16 to adjust the distance between the scraper block 46 and the roller 47 and the hemisphere 12, so that the roller 47 can be against the welding part of the hemisphere 12 to apply anti-splash paint, and the scraper block 46 is inserted into the gap to scrape off excess paint to prevent the paint from affecting the welding between the hemispheres 12; when adjusting the roller 47 to apply paint, the first threaded rod 21 rotates to rotate the transmission wheel 23, which is transmitted through the transmission belt 11 to rotate the other transmission wheel 23, thereby rotating the second threaded rod 13 to cause the lifting frame 24 to slide on the two fixed plates 9 to adjust the height of the first slide 17, so that the roller 47 and the scraper block 46 can better apply paint to 12.
