Description

Technical Field

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

[0002] In steel structure buildings, hollow node balls are used to connect 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. A patent with publication number CN118371955B discloses a method for welding nodes of building steel structures, including a workbench, which drives the driving sprocket to rotate through a driving motor to rotate the corresponding roller, and cooperates with the clamping device to drive the welding ball placed on 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 anti-splash material is brushed on both sides of the weld through the brushing device. During the second circle, the brushing device automatically stops brushing the weld, and the operator can fully weld the weld, which speeds up the production rhythm and improves welding efficiency.

[0003] The above scheme does not improve the clamping and fixing of the node ball when welding the node ball, and still uses traditional clamping equipment such as threaded rotation to fix the node ball on the fixing equipment. The angle and position 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 take time and effort to fix the node ball, but it also causes deviations in the fixing position and angle of the node ball, resulting in deviations in the weld of the welded node ball, which reduces the efficiency of welding the node ball and deteriorates the welding effect.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] Embodiment 1: Figures 1 to 9As shown, a building steel structure node welding device described in an embodiment of the present invention includes a welding platform 1, two fixing devices are provided on one side of the welding platform 1, and the two fixing devices are arranged opposite to each other. The fixing device includes a sliding plate 28 slidably connected to one side of the welding platform 1, and a plurality of connection frames 31 are slidably connected to one side of the sliding plate 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 hemisphere 12. A first motor 2 is fixedly connected to one side of the welding platform 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 platform 1, and the two transmission rods 7 are rotatably connected to the output end of the first motor 2. A driven gear 5 is fixedly connected to one end of the moving rod 7 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 plate 17, one end of the first slide plate 17 is rotatably connected to two rollers 47, a liquid inlet pipe 48 is provided in the first slide plate 17, and the coating device is used to apply anti-splash coating to the welding point of the two hemispheres 12.

[0022] Specifically, at present, when welding a node ball, workers are required to fix the two halves of the node ball by tightening the fixing device 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 ball is initially spot welded to fix it by arc welding with electrodes, and then anti-splash coating is applied near the welding point of the node ball 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 ball are fully welded to complete the welding of the node ball. The staff fixes half of the node ball on the fixing device, and manually adjusts the angle and position of the node ball, which not only results in the problem of time-consuming and labor-intensive fixing of the node ball, but also causes deviations in the fixing position and angle of the node ball, resulting in deviations in the weld seam of the welded node ball, resulting in reduced efficiency in welding the node ball and poor welding effect.

[0023] 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 abut against each other. When the two hemispheres 12 abut 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 to place the two hemispheres 12 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 the two hemispheres 12 are arc welded with 316 stainless steel electrodes. The 316 stainless steel electrodes belong to 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. Move the welding head 15 to one side of the hemisphere 12, and then spot weld the two hemispheres 12 with the welding rod to preliminarily fix the two hemispheres 12, then move the first slide 17 and the roller 47 close to the contact point of the two hemispheres 12, input the coating into the roller 47 through the liquid inlet pipe 48, and apply the coating to the side of the weld of the hemisphere 12 through the roller 47, and apply anti-splash coating to the welding point of the two hemispheres 12 through the coating device to prevent welding slag and sparks from splashing. After the anti-splash coating 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 fixes the hemisphere 12, so that the hemisphere 12 can be fixed more quickly for welding, without the need for the operator to manually fix and adjust the docking point of the hemisphere 12. When the fixing device is against the hemisphere 12, the welding point of the two hemispheres 12 will automatically adjust to a vertical state for welding, thereby reducing the fixing time of the node ball and speeding up the welding efficiency of the node ball.

[0024] like Figure 2 As shown, both ends of the two transmission rods 7 are rotatably connected with 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 with bidirectional screw rods 8, and the two bidirectional screw rods 8 are threadedly connected to the two first sliders 6 on one side.

[0025] 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 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.

[0026] like Figure 6 As shown, a spacing wheel 10 is fixedly connected to one side of the two transmission rods 7. The two spacing wheels 10 are located between the two hemispheres 12 and are provided with a spacing ring. The two spacing wheels 10 are used to space the hemispheres 12 for welding.

[0027] Specifically, when the two hemispheres 12 abut against each other, the two hemispheres 12 will abut against the two 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.

[0029] 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 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 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 in a vertical state and leave a gap, which is more convenient for welding the two hemispheres 12.

[0031] Specifically, when spacing the two hemispheres 12 , press one side of the connecting frame 45 to rotate the card block 42 to move the card block 42 out of the card slot 43 , and move the card block 42 to slide out of the dividing frame 38 with the telescopic plate 39 , so that the telescopic plate 39 can be extended to space the two hemispheres 12 .

[0032] 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 meshedly connected with the toothed disk 30. One side of the toothed disk 30 is provided with a plurality of arc grooves, and the toothed disk 30 is slidably connected to the connecting frame 31 through the arc grooves.

[0033] 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 moving the magnetic ball 32 with multiple connecting frames 31 to adjust the size.

[0034] like Figure 4As shown, adjusting devices are provided on both sides of the welding table 1, and the adjusting devices include a second motor 18 fixedly connected to one side of the welding table 1, and fixed plates 9 are fixedly connected to both sides of the welding table 1, and 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, and 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, and a third slide plate 34 is slidably connected to the outer side of the sliding plate 28, and the sliding plate 28 is fixed to the second slide plate 25.

[0035] 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 plate 34 with the sliding plate 28 through the second slide plate 25, and the hemisphere 12 fixed on the fixing device can be moved up and down. The height of the hemisphere 12 is adjusted and the hemisphere 12 is placed on the transmission rod 7 for welding.

[0036] like Figure 5 As shown, the adjusting device also includes a third motor 26 fixedly connected to one side of the lifting plate 19, a threaded barrel 27 is fixedly connected to the output end of the third motor 26, a sleeve 35 is fixedly connected to one side of the sliding disk 28, the threaded barrel 27 is threadedly connected to the sleeve 35, a connecting rod 36 is slidably connected inside the threaded barrel 27, and the connecting rod 36 is fixedly connected to the connecting gear 29.

[0037] Specifically, when the sliding disk 28 is moved to make the hemispheres 12 abut against each other, the third motor 26 is started to rotate the threaded barrel 27. The threaded barrel 27 rotates to make the sleeve 35 push the sliding disk 28 and the third slide plate 34 to slide on the welding table 1, thereby pushing the two hemispheres 12 to abut against 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. The connecting gear 29 rotates to make the toothed disk 30 rotate to adjust the distance between the multiple magnetic balls 32 to fix the hemispheres 12.

[0038] Embodiment 2: as Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is: A lifting frame 24 is slidably connected between the two fixed plates 9 , and the coating device includes a connecting block 16 fixedly connected to one side of the lifting frame 24 , the connecting block 16 is slidably connected to a first slide plate 17 , and one end of the first slide plate 17 is located between the two rollers 47 and fixedly connected to a scraper block 46 .

[0039] 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 scraper 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 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.

[0040] 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 through a transmission belt 11, and the lifting frame 24 is threadedly connected to the second threaded rod 13.

[0041] 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 another 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 block 46 can better apply paint to 12.
