Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and more specifically, to a welding device for processing steel structure crossbeams. Background Art

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. A steel structure is mainly composed of components such as beam steels, steel columns, and steel trusses supported by section steels and steel plates. Welds, bolts, or rivets are usually used to connect between the components or parts. Due to its light self-weight and convenient construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.

[0003] When the existing welding device is performing multi-node welding operations on a cylindrical crossbeam, there are significant process limitations. Due to the curved surface characteristics of the crossbeam and the differences in node distributions, it is difficult for traditional fixtures to achieve multi-angle adaptive positioning. As a result, during the welding process, it is necessary to frequently adjust the clamping positions and fixing methods. This repeated mechanical adjustment not only prolongs the process cycle but also easily causes uneven distribution of clamping force, thereby affecting the forming quality of the welded joint. In addition, the conventional welding tooling has insufficient fixing accuracy for the node positions and is prone to micro-displacements under the action of high-temperature welding stress, directly resulting in weld offset or porosity defects. Summary of the Invention

Detailed implementation manners

[0026] 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.

[0027] Please refer to Figures 1 to 6, a steel structure crossbeam processing and welding device, including a base 1. Support legs 2 are fixedly installed at the four corners of the lower end surface of the base 1. A first slide rail 3 is fixedly installed on the upper end surface of the base 1. A groove 4 is opened on the upper end surface of the base 1. A turntable 5 is arranged inside the groove 4. A crossbeam main body 6 is arranged above the turntable 5. A welding mechanism is arranged above the base 1. The welding mechanism includes an adjusting member arranged inside the first slide rail 3. The adjusting member includes a motor 7 fixedly installed on the upper end surface of the first slide rail 3. A first reciprocating lead screw 8 is rotatably connected inside the first slide rail 3. A second reciprocating lead screw 10 is arranged at the rear side of the first slide rail 3. The output shaft of the motor 7 extends into the first slide rail 3 and is fixedly connected to the first reciprocating lead screw 8. The second reciprocating lead screw 10 is rotatably connected to the base 1. A first gear 9 is arranged below the base 1. The lower end of the first reciprocating lead screw 8 extends below the base 1 and is fixedly connected to the first gear 9. A second gear 11 is meshed with one side of the first gear 9. The lower end of the second reciprocating lead screw 10 extends below the base 1 and is fixedly connected to the second gear 11. A one-way bearing is arranged inside the second gear 11.

[0028] The thread groove on the outer surface of the first reciprocating lead screw 8 is a one-way thread groove, and the thread groove on the outer surface of the second reciprocating lead screw 10 is a two-way thread groove.

[0029] Thread sleeves 31 are helically driven and connected to both the upper side and the lower side of the outer surface of the second reciprocating lead screw 10. Two connecting rods 12 are rotatably connected to both sides of the outer surface of each thread sleeve 31. Top blocks 13 are arranged on both sides of the second reciprocating lead screw 10. The two groups of connecting rods 12 on the same side are rotatably connected to the corresponding top blocks 13.

[0030] A second slide rail 14 is fixedly installed on the front end surface of the top block 13. A first slider 15 is slidably connected inside the second slide rail 14. A sliding rod 16 is fixedly installed on the front end surface of the first slider 15. A welding torch 20 is arranged at the end of the sliding rod 16.

[0031] A second slider 17 is slidably connected inside the first slide rail 3. The second slider 17 is helically driven and connected to the first reciprocating lead screw 8. A cross bar 18 is fixedly installed on the front end surface of the second slider 17. A chute 19 is opened on the front end surface of the cross bar 18. The sliding rod 16 is slidably connected to the chute 19.

[0032] After the crossbeam main body 6 is fixed, the motor 7 is driven to reverse the first reciprocating lead screw 8. At this time, the second reciprocating lead screw 10 will not rotate under the action of the one-way bearing, and the first reciprocating lead screw 8 rotates alone. A second slider 17 is helically driven and connected to the outer surface of the first reciprocating lead screw 8. The second slider 17 will displace inside the first slide rail 3 under the action of the first reciprocating lead screw 8. The cross bar 18 fixedly installed on the front end surface of the second slider 17 displaces synchronously, so as to adjust the orientation of the two sliding rods 16. The first slider 15 at the rear end of the sliding rod 16 will slide inside the second slide rail 14. After adjusting to an appropriate orientation, the welding torch 20 can be started for welding. The turntable 5 synchronously drives the crossbeam main body 6 to rotate, and then the crossbeam main body 6 can be subjected to a full-range welding treatment.

[0033] The welding mechanism also includes a stabilizing member arranged on the upper side of the crossbeam body 6, and the stabilizing member includes a fixing member 21 fixedly installed on the upper end of the slide rail 14, the fixing member 21 is arranged in an L shape, and a clamping plate 22 is fixedly installed on the end of the fixing member 21, and the inner wall of the clamping plate 22 is rotatably connected to multiple groups of ball bearings 23.

[0034] Place the beam body 6 to be welded on the turntable 5 in the groove 4, and then drive the motor 7 as needed to make the motor 7 carry the reciprocating screw 8 and the gear 9 to rotate, and the gear 11 on the reciprocating screw 10 is meshed with the gear 19, but a one-way bearing is arranged inside the gear 11. When the gear 19 rotates forward, the reciprocating screw 10 will be driven to rotate under the action of the gear 11 and the one-way bearing, and the gear 19 will not drive the reciprocating screw 10 to rotate when it is reversed. Therefore, the reciprocating screw 8 first rotates forward to drive the reciprocating screw 10 to rotate. The thread groove on the outer surface of the reciprocating screw 10 is a bidirectional thread groove. Therefore, the outer surface of the reciprocating screw 10 The two groups of threaded sleeves 31 connected by the spiral transmission will move relative to each other, and carry the two groups of connecting rods 12 to be displaced respectively. The two groups of connecting rods 12 on the same side are rotatably connected with the corresponding top blocks 13, so that the two groups of top blocks 13 can move toward each other, and carry their respective slide rails 14 to be displaced inwardly, and the welding gun 20 on the slide rail 14 will approach the beam body 6 to facilitate welding operations. At the same time, the upper ends of the two groups of slide rails 14 carry a group of clamping plates 1 22 for displacement through the fixing parts 21, and the two groups of symmetrically arranged clamping plates 1 22 will approach the beam body 6 with the displacement of the slide rail 14, and make the roller 1 close to the beam body 6 for limit fixing.

[0035] The welding mechanism further includes a reinforcement member arranged inside the groove 4 . The reinforcement member includes an air bag 24 arranged inside the slide groove 19 . The air bag 24 is fixedly installed between the slide rod 16 and the inner wall of the slide groove 19 .

[0036] An inner cavity 26 is provided inside the base 1 , and a connecting pipe 25 is provided between the inner cavity 26 and the air bag 24 . The inner cavity 26 is arranged in an annular shape outside the groove 4 .

[0037] The inner wall of the groove 4 is provided with a limit cavity 27, which is communicated with the inner cavity 26. A push rod 28 is slidably connected inside the limit cavity 27, and a second clamping plate 29 is fixedly installed at one end of the push rod 28. The inner wall of the second clamping plate 29 is rotatably connected with multiple sets of second balls 30.

[0038] The limiting cavity 27 , the push rod 28 , the second clamping plate 29 and the plurality of groups of balls are provided in three groups and are dispersedly arranged in a ring shape. The three groups of limiting cavities 27 are interconnected with the inner cavity 26 .

[0039] Secondly, the slide bar 16 is slidably connected in the slide groove 19. When the slide bar 16 moves inward, it will squeeze the airbag 24, so that the gas inside the airbag 24 enters the inner cavity 26 through the connecting tube 25, and finally enters the limiting cavity 27, so that the top rod 28 slidably connected inside the limiting cavity 27 is extended, and the second splint 29 at the end of the top rod 28 approaches the beam body 6, and finally the ball 2 30 is close to the beam body 6, and the three groups of splints 29 cooperate with each other to complete the limiting fixation of the beam body 6.

[0040] The existing welding devices have significant process limitations when performing multi-node welding operations on cylindrical beams. Due to the curved surface characteristics of the beams and the differences in node distribution, it is difficult for traditional clamps to achieve multi-angle adaptive positioning, resulting in the need to frequently adjust the clamping position and fixing method during the welding process. This repeated mechanical adjustment not only prolongs the process cycle, but also easily causes the problem of uneven clamping force distribution, thereby affecting the forming quality of the welded joint. In addition, the conventional welding tooling has insufficient fixing accuracy for the node position, and is prone to micro-displacement under the action of high-temperature welding stress, which directly leads to weld offset or porosity defects. Therefore, this solution sets up a welding mechanism, and uses the adjustment parts inside the welding mechanism to perform adaptive adjustment welding for different nodes of the same beam, thereby increasing the practicality of the equipment. At the same time, the stabilizing parts and reinforcing parts can increase the fixing effect of the beam body 6, further improving the stability of the beam body 6 during welding.

[0041] Usage: Place the crossbeam body 6 to be welded on the turntable 5 in the groove 4, and then drive the motor 7 as needed to make the motor 7 carry the reciprocating screw 8 and the gear 9 to rotate, and the gear 11 on the reciprocating screw 10 is meshed with the gear 19, but the gear 11 is provided with a one-way bearing inside. When the gear 19 rotates forward, it will drive the reciprocating screw 10 to rotate under the action of the gear 11 and the one-way bearing, and the gear 19 will not drive the reciprocating screw 10 to rotate when it is reversed. Therefore, the reciprocating screw 8 first rotates forward to drive the reciprocating screw 10 to rotate. The thread groove on the outer surface of the reciprocating screw 10 is a two-way thread groove. Therefore, the reciprocating screw 10 The two sets of threaded sleeves 31 connected by the spiral transmission on the outer surface will move relative to each other, and carry the two sets of connecting rods 12 to move respectively. The two sets of connecting rods 12 on the same side are rotatably connected with the corresponding top blocks 13, so that the two sets of top blocks 13 can move toward each other, and carry their respective slide rails 14 to move inwards, and the welding gun 20 on the slide rail 14 will move closer to the beam body 6 for welding. At the same time, the upper ends of the two sets of slide rails 14 carry a set of clamping plates 1 22 for displacement through the fixing parts 21. The two sets of symmetrically arranged clamping plates 1 22 will move closer to the beam body 6 with the displacement of the slide rails 14, and make the roller 1 close to the beam body 6 for limit fixing;

[0042] Secondly, the slide bar 16 is slidably connected in the slide groove 19. When the slide bar 16 moves inward, it squeezes the airbag 24, so that the gas inside the airbag 24 enters the inner cavity 26 through the connecting pipe 25, and finally enters the limit cavity 27, so that the push rod 28 slidably connected inside the limit cavity 27 extends out, and the second clamping plate 29 at the end of the push rod 28 approaches the beam body 6, and finally the second ball 30 is close to the beam body 6. The three groups of second clamping plates 29 cooperate with each other to complete the limit fixation of the beam body 6;

[0043] After the crossbeam body 6 is fixed, the motor 7 drives the reciprocating screw rod 8 to reverse. At this time, the reciprocating screw rod 10 will not rotate under the action of the one-way bearing, and the reciprocating screw rod 8 rotates alone. The outer surface of the reciprocating screw rod 8 is spirally connected with a slider 2 17. The slider 2 17 will be displaced inside the slide rail 3 under the action of the reciprocating screw rod 8, and the cross bar 18 fixedly installed on the front end face of the slider 2 17 will be displaced synchronously, thereby adjusting the orientation of the two groups of slide rods 16, and the slider 15 at the rear end of the slide rod 16 will slide inside the slide rail 2 14. After adjusting to the appropriate orientation, the welding gun 20 can be started for welding, and the turntable 5 synchronously drives the crossbeam body 6 to rotate, so that the crossbeam body 6 can be welded in all directions.

[0044] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
