Description

Technical Field

[0001] The invention belongs to the technical field of building construction, in particular to a welding auxiliary device for building construction. Background Art

[0002] Construction steel bars are the most commonly used steel in construction projects. They are widely used in concrete structures and reinforced concrete structures to strengthen and enhance concrete components and improve their tensile strength and bearing capacity. At present, a large number of discarded short steel bars are usually generated during construction. Most of these discarded short steel bars are cut from long steel bars. In order to avoid the waste of steel bar materials, it is necessary to weld the short steel bars to achieve the extension and continuation of the steel bars and realize the reuse of the discarded short steel bars.

[0003] In the prior art, the extension welding of short steel bars is mostly carried out with the aid of welding machines. When the existing welding machines are used to weld short steel bars, a clamping mechanism is required to clamp the two steel bars to be welded so that the two steel bars can butt against each other. However, since the short steel bars to be welded are cut from long steel bars, and the cutting of steel bars usually involves shearing and cutting, sharp protrusions will be formed at the cross section when the steel bars are cut. When the steel bars are cut, their cross sections are sometimes affected by the cutting angle and are prone to being tilted. Therefore, when the cross section of the discarded short steel bars is used as the subsequent welding surface, it is easy to cause the two short steel bars to be unable to be accurately butted together, or even if the two short steel bars can be accurately butted together, the two short steel bars after butt are prone to a certain angle, that is, the two short steel bars are not in the same straight line, which affects the subsequent welding quality and makes the welded steel bars unable to be put into use.

[0044] See also Figure 1 as well as Figure 2The present embodiment provides a welding auxiliary device for construction, including a welding support platform 10, a clamping assembly 30, a leveling assembly 40, a first drive assembly 50, a second drive assembly 60 and a laser welding head 70. The clamping assembly 30 is provided with two groups, and the two groups of the clamping assemblies 30 are arranged on the upper part of the welding support platform 10 and are relatively distributed, and are used to clamp two steel bars to be welded respectively. A first U-shaped bracket plate 102 is fixedly arranged on the upper part of the welding support platform 10, and the first U-shaped bracket plate 102 is located between the two groups of the clamping assemblies 30. The leveling assembly 40 and the The laser welding head 70 is arranged on the inner side of the first U-shaped bracket plate 102, and the first driving component 50 and the second driving component 60 are installed on the inner wall of the first U-shaped bracket plate 102. The first driving component 50 is used to drive the leveling component 40 to rotate so as to level the welding surfaces of the two steel bars to be welded. When the welding surfaces of the two steel bars to be welded are leveled, the second driving component 60 drives the leveling component 40 to move so that the leveling component 40 is removed from between the two steel bars to be welded, and the laser welding head 70 welds the two steel bars into one after the welding surfaces are leveled.

[0045] When welding is required for two steel bars, two groups of clamping assemblies 30 can be used to clamp the two steel bars respectively. After the two steel bars are clamped, they are relatively distributed on the upper part of the welding support platform 10. Then, the first driving assembly 50 drives the leveling assembly 40 to rotate. When the leveling assembly 40 rotates, the welding surface of the two steel bars is leveled. Then, the second driving assembly 60 drives the leveling assembly 40 to move, so that the leveling assembly 40 is removed from between the two steel bars. Finally, the two steel bars with the leveled welding surfaces are welded into one by the laser welding head 70.

[0046] See also Figure 1 In one embodiment, the leveling assembly 40 includes a turntable 401, an outer gear ring 402 and an annular grinding sheet 404. The annular grinding sheet 404 is provided with two groups. The two groups of annular grinding sheets 404 are respectively fixedly arranged on opposite sides of the turntable 401. The outer gear ring 402 is fixedly arranged on the circumferential side wall of the turntable 401. The first driving assembly 50 includes a second U-shaped bracket plate 501, a driving motor 502 and a driving gear 503. The driving motor 502 is fixedly installed on the outer wall of the second U-shaped bracket plate 501. A part of the turntable 401 extends to the inner side of the second U-shaped bracket plate 501 and rotates with the second U-shaped bracket plate 501. The driving gear 503 is arranged on the inner side of the second U-shaped bracket plate 501 and is controlled to rotate by the driving motor 502. The driving gear 503 is meshed with the outer gear ring 402.

[0047] After the two steel bars to be welded are clamped and fixed by the two groups of clamping assemblies 30 respectively, the welding surfaces of the two steel bars are in contact with the two groups of annular grinding discs 404 respectively, and then the driving motor 502 drives the driving gear 503 to rotate, and the meshing action of the driving gear 503 and the outer gear ring 402 drives the turntable 401 to rotate. When the turntable 401 rotates, it drives the two groups of annular grinding discs 404 to rotate. The two groups of annular grinding discs 404 grind the welding surfaces of the two steel bars respectively, so as to smooth the welding surfaces of the two steel bars, so that the two steel bars can be accurately and comprehensively fitted during subsequent welding, thereby improving the welding quality.

[0048] See also Figure 1 as well as Figure 6 In one embodiment, a welding alignment hole 405 is opened at the center position of the turntable 401, and the laser welding head 70 is installed on the wall of the welding alignment hole 405. The two groups of clamping assemblies 30 can slide toward each other along the upper part of the welding support platform 10. Two groups of elastic support assemblies 20 are arranged on the upper part of the welding support platform 10. The two groups of elastic support assemblies 20 are respectively located at one end of the two groups of clamping assemblies 30 away from each other, and the two groups of elastic support assemblies 20 are used to provide elastic support to the two groups of clamping assemblies 30 respectively.

[0049] The two sets of elastic support components 20 provide elastic support to the two sets of clamping components 30 respectively, and then provide elastic support to the two steel bars, so that the welding surfaces of the two steel bars are in close contact with the two sets of annular grinding sheets 404 respectively, and the two sets of annular grinding sheets 404 rotate to smoothly grind the welding surfaces of the two steel bars; while the driving motor 502 drives the driving gear 503 to rotate and then drives the turntable 401 and the two sets of annular grinding sheets 404 to rotate through the meshing action of the driving gear 503 and the outer gear ring 402, the second driving component 60 drives the turntable 401 and the two sets of annular grinding sheets 404 to gradually move downward, and when the two sets of annular grinding sheets 404 are in close contact with each other, the two sets of annular grinding sheets 404 are in close contact with each other. 04 After the welding surfaces of the two steel bars are polished and leveled, the welding surfaces of the two steel bars slide from the inner sides of the two sets of annular polishing sheets 404 to the positions of the welding alignment holes 405. At this time, through the elastic support of the two sets of elastic support assemblies 20, the two sets of clamping assemblies 30 slide toward each other along the upper part of the welding support platform 10, thereby driving the two steel bars to move toward each other. The ends of the two steel bars with welding surfaces extend toward each other into the welding alignment holes 405 and dock with each other. Then, as the driving motor 502 continues to drive the turntable 401 to rotate, the turntable 401 drives the laser welding head 70 to rotate, and the laser welding head 70 rotates around the two steel bars, thereby welding the two steel bars into one.

[0050] See also Figure 6In one embodiment, a positioning slider 504 is fixedly provided on the inner wall of the second U-shaped bracket plate 501, and a positioning ring groove 403 is opened on the edge of the side wall of the turntable 401. The center of the positioning ring groove 403 coincides with the center of the turntable 401, and the positioning slider 504 extends from one end of the second U-shaped bracket plate 501 to the inside of the positioning ring groove 403 and rotates with the turntable 401.

[0051] Through the cooperation between the positioning slider 504 and the positioning ring groove 403, the second U-shaped bracket plate 501 can provide stable support for the turntable 401. When the driving motor 502 drives the driving gear 503 to rotate, the meshing action of the driving gear 503 and the outer gear ring 402 can make the turntable 401 rotate smoothly compared with the second U-shaped bracket plate 501, thereby driving the two sets of annular grinding plates 404 to rotate smoothly compared with the two steel bars, thereby achieving smooth grinding of the welding surfaces of the two steel bars.

[0052] See also Figure 1 , Figure 4 as well as Figure 5 In one embodiment, the second drive assembly 60 includes an L-shaped elbow 601, a piston sleeve 602, a first piston rod 603, a second piston rod 604 and a transmission rack 606, the piston sleeve 602 is fixedly arranged on the upper part of the second U-shaped bracket plate 501, the first piston rod 603 is fixedly arranged on the inner top wall of the first U-shaped bracket plate 102, the lower end of the first piston rod 603 extends to the interior of the piston sleeve 602 and is telescopically matched with the piston sleeve 602, the L-shaped elbow 601 is fixedly arranged on the side wall of the piston sleeve 602 and is connected to the inner cavity of the piston sleeve 602, one end of the second piston rod 604 extends to the interior of the L-shaped elbow 601 and is telescopically matched with the L-shaped elbow 601, and the other end extends to one side of the driving gear 503, and the transmission rack 606 is fixedly installed on the side wall of the second piston rod 604 and meshes with the driving gear 503.

[0053] When the driving motor 502 drives the driving gear 503 to rotate, and then drives the turntable 401 and the two sets of annular grinding plates 404 to rotate through the meshing action of the driving gear 503 and the outer gear ring 402, the second piston rod 604 is driven to move upward compared to the L-shaped elbow 601 through the meshing action of the driving gear 503 and the transmission rack 606. When the second piston rod 604 moves upward, the air inside the L-shaped elbow 601 is pressed into the piston sleeve 602. After the air enters the piston sleeve 602, it pushes the piston sleeve 602 makes the piston sleeve 602 move downward compared to the first piston rod 603, thereby driving the second U-shaped bracket plate 501, the driving motor 502, the driving gear 503, the turntable 401 and the two sets of annular grinding discs 404 to move downward as a whole. The two sets of annular grinding discs 404 move downward compared to the two steel bars, so that the two steel bars gradually move toward the center position of the turntable 401. When the two steel bars move to the center position of the turntable 401, that is, the position where the welding alignment hole 405 is located, the two sets of elastic support components 20 push the two sets of elastic support components 20 to move downward. The two sets of clamping assemblies 30 are moved toward each other, thereby driving the two steel bars to move toward each other. The ends of the two steel bars with welding surfaces extend into the welding alignment holes 405 and are butted against each other. After the butt is butted against each other, as the turntable 401 continues to move downward, the two steel bars move upward along the welding alignment holes 405. When the two steel bars move to the center of the welding alignment holes 405, the driving gear 503 is disengaged from the transmission rack 606, and the second piston rod 604 stops moving upward. , and then stop pressing air into the piston sleeve 602, the piston sleeve 602, the second U-shaped bracket plate 501, the drive motor 502, the drive gear 503, the turntable 401 and the two sets of annular grinding sheets 404 stop moving downward, and at this time, the turntable 401 continues to rotate through the meshing action of the drive gear 503 and the outer gear ring 402, thereby driving the laser welding head 70 to rotate around the two steel bars. When the laser welding head 70 rotates, it emits a laser toward the docking position of the two steel bars to weld the two steel bars circumferentially into one.

[0054] See also Figure 4 In one embodiment, a second elastic member 605 is further provided inside the piston sleeve 602 , one end of the second elastic member 605 is connected to the first piston rod 603 , and the other end is connected to the piston sleeve 602 , for providing elastic tension to the piston sleeve 602 .

[0055] When the driving gear 503 rotates and drives the second piston rod 604 to move upward through the meshing action with the transmission rack 606, the second piston rod 604 presses the air inside the L-shaped elbow 601 into the piston sleeve 602, thereby driving the piston sleeve 602 to move downward compared with the first piston rod 603. At this time, the second elastic member 605 is stretched and elongated; when the two steel bars are welded, the driving motor 502 drives the driving gear 503 to rotate in the opposite direction. At this time, the second elastic member 605 pulls the piston sleeve 602 to drive the piston sleeve 602 to move upward compared with the first piston rod 603. 2 drives the second U-shaped bracket plate 501, the driving motor 502, the driving gear 503, the turntable 401 and the two sets of annular grinding discs 404 to move upward, so as to realize the reset of the turntable 401 and the annular grinding discs 404. When the piston sleeve 602 moves upward, the air inside it is pressurized and then enters the L-shaped elbow 601 in the reverse direction, thereby driving the second piston rod 604 to move downward compared with the L-shaped elbow 601. The second piston rod 604 drives the transmission rack 606 to move downward, and the transmission rack 606 enters into a meshing state with the driving gear 503 again, thereby driving the second piston rod 604 to continue to move downward, thereby realizing the reset of the second piston rod 604.

[0056] See also Figure 1 In one embodiment, the welding support platform 10 is provided with a slot 103 through which the turntable 401 and two sets of annular grinding sheets 404 can pass.

[0057] When the turntable 401 and the two sets of annular grinding discs 404 move downward, they can pass through the notch 103, so that the two steel bars can be smoothly moved to the side of the welding alignment hole 405 and extend into the welding alignment hole 405, so as to be smoothly butted.

[0058] See also Figure 1 as well as Figure 3 In one embodiment, the clamping assembly 30 includes a clamping seat 301, a locking bolt 303, a slide seat 304 and a slide rail 305. The upper portion of the clamping seat 301 is provided with a receiving groove 302 for placing steel bars. The locking bolt 303 is arranged on the side wall of the clamping seat 301. The slide rail 305 is fixedly arranged on the upper portion of the welding support platform 10. The slide seat 304 is fixedly arranged at the bottom of the clamping seat 301 and slidably cooperates with the slide rail 305.

[0059] The steel bar to be welded is placed into the receiving groove 302 and then the locking bolt 303 is turned so that the locking bolt 303 is screwed into the receiving groove 302, thereby supporting the steel bar against the inner wall of the receiving groove 302 to achieve clamping and fixing of the steel bar; when the two steel bars are welded, the locking bolt 303 can be turned in the reverse direction, and one end of the locking bolt 303 is separated from the steel bar and withdrawn from the receiving groove 302 to release the supporting and fixing state of the steel bar, and then the two steel bars welded as one are taken out from the corresponding receiving grooves 302 respectively, and then the two steel bars welded as one are pulled out from the welding alignment holes 405, and finally the driving motor 502 is used to drive the driving gear 503 to rotate in the reverse direction to reset the turntable 401, the two sets of annular grinding discs 404 and the second piston rod 604.

[0060] See also Figure 1 as well as Figure 3 In one embodiment, the elastic support assembly 20 includes a support seat 201 and a first elastic member 202. The support seat 201 is fixedly arranged on the upper part of the welding support platform 10. One end of the first elastic member 202 is connected to the support seat 201, and the other end is connected to the clamping seat 301, for providing elastic support to the clamping seat 301.

[0061] Through the elastic support of the first elastic member 202 on the clamping seat 301, the welding surfaces at one end of the two steel bars can be closely contacted with the two groups of annular grinding sheets 404 respectively, so that the welding surfaces of the two steel bars can be smoothly polished and leveled when the two groups of annular grinding sheets 404 rotate; when the welding surfaces of the two steel bars are leveled, as the turntable 401 moves downward, the welding surfaces at one end of the two steel bars move to the side of the welding alignment hole 405, and the first elastic member 202 pushes the clamping seat 301 so that the clamping seat 301 drives the slide seat 304 to slide along the slide rail 305, and the clamping seat 301 pushes the two steel bars so that the ends of the two steel bars with the welding surfaces move to the inside of the welding alignment hole 405 and complete the docking inside the welding alignment hole 405.

[0062] In one embodiment, the first elastic member 202 and the second elastic member 605 may be springs or metal springs, which are not limited herein.

[0063] See also Figure 1 as well as Figure 2 In one embodiment, a plurality of legs 101 are fixedly disposed at the bottom of the welding support platform 10 .

[0064] In the embodiment of the present invention, when it is necessary to weld two steel bars, two groups of clamping assemblies 30 can be used to clamp the two steel bars respectively. After the two steel bars are clamped, they are relatively distributed on the upper part of the welding support platform 10. Then, the first driving assembly 50 drives the leveling assembly 40 to rotate. When the leveling assembly 40 rotates, the welding surfaces of the two steel bars are leveled. Then, the second driving assembly 60 drives the leveling assembly 40 to move, so that the leveling assembly 40 is removed from between the two steel bars. Finally, the two steel bars with leveled welding surfaces are welded into one by the laser welding head 70. Compared with the prior art, when welding two steel bars into one, the welding surfaces of the two steel bars can be leveled in advance, so that the two steel bars can be accurately and fully connected in a straight line during the subsequent welding process, thereby improving the welding quality of the steel bars.
