Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and specifically relates to a correction auxiliary device for steel structure welding. Background Technique

[0002] With the rapid development of the economy, China's infrastructure construction has been developing faster and faster. In infrastructure construction, a large number of steel structure components are applied. A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Between components or parts, they are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.

[0003] When existing steel structures are used, the steel structures need to be welded. Steel pipes belong to one of the steel structures. During welding, the workpieces cannot be well fixed, and the workpieces on both sides are prone to dislocation, thus affecting the welding effect. Moreover, the welding position cannot be fully welded. If the steel pipes are manually driven during welding, the two steel pipes are prone to dislocation, affecting the welding. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A correction auxiliary device for steel structure welding, including a base, a slide rail is fixedly connected to the top of the base, a moving block is slidably connected to the outside of the slide rail, and the number of moving blocks is two; A welding assembly, the welding assembly is fixedly installed in the middle of the base, the welding assembly penetrates through the base, and the two moving blocks are symmetrically arranged with the welding assembly as the center; A fixing assembly, the fixing assembly is fixedly installed in the middle of the slider, and the fixing assembly is arranged parallel to the slide rail; Among them, the fixing component includes a fixing plate which is fixedly installed in the middle of the moving block. A motor is fixedly connected to the outside of the fixing plate. The output end of the motor is fixedly connected with a gear. A ring is fixedly connected to the middle of the fixing plate. An extension ring is fixedly connected to the inside of the ring. A ring groove is formed on the outside of the extension ring, and through holes are formed on the inner wall of the extension ring. A toothed ring is rotatably connected to the outer side inside the ring. Place the workpiece to be processed on the fixing component so that the workpiece penetrates through the middle of the extension ring. At this time, the motor is powered on to work. The motor drives the gear to rotate, so that the gear drives the toothed ring to rotate. Thus, the toothed ring drives the bent plate to move. At the same time, the round rod slides inside the ring groove, so that multiple bent plates move towards the workpiece in the middle to clamp the workpiece, keeping the workpiece in the correct relative position during welding and reducing deformation caused by welding stress. By setting multiple bent plates, the workpiece can be fixed from different directions and angles, dispersing the force on the fixing points, effectively preventing the workpiece from displacing, deforming or shaking due to the influence of welding stress during the welding process, ensuring that the workpiece maintains a stable position during welding, and providing a basic guarantee for high-quality welding. The toothed rings are symmetrically arranged with the extension ring as the center. A round rod is fixedly connected to the side of the toothed ring close to the extension ring. The two ends of the round rod are fixedly connected to the two toothed rings. The outside of the round rod is rotatably connected with bent plates. The number of bent plates is multiple, and the multiple bent plates are evenly distributed with the toothed ring as the center. The bent plates penetrate through the extension ring through the through holes.

[0005] Preferably, a rotating rod is rotatably connected to the inner wall of the circular ring. There are multiple rotating rods, and the multiple rotating rods are evenly distributed around the circular ring. The rotating rods are rotatably connected to the outer side of the toothed ring. The round rod passes through the extension ring through the ring groove. The bent plate is located inside the extension ring. One side of the bent plate is fixedly connected with a compression spring. By setting the compression spring, the bent plate clamps the workpiece. During the welding process, the workpiece will expand due to heat and contract when cooled. The compression spring can absorb and compensate for this thermal deformation of the welded part to a certain extent, avoid excessive stress generated inside the workpiece due to rigid fixation, and reduce the possibility of welding deformation and crack generation. The end of the bent plate far from the round rod is fixedly connected with a positioning rod. The end of the compression spring far from the bent plate is fixedly connected with the extension ring. The compression spring is located inside the extension ring. A fixed seat is fixedly connected to the inner wall of the toothed ring. A connecting rod is rotatably connected to the outer side of the fixed seat. There are multiple connecting rods. The motor is powered on to work. The motor drives the gear to rotate, so that the gear drives the toothed ring to rotate, and the toothed ring drives the fixed seat to move. Under the connection of the connecting rod, the contact frame rotates around the positioning rod, thereby adjusting the angle of the contact frame, so that the contact frame can better adapt to the surface shape of the workpiece, realize all-round close fitting, reduce the shaking and displacement of the workpiece during the welding process, and facilitate adapting to workpieces of various shapes and sizes. This not only reduces the procurement and manufacturing costs of the fixture, but also reduces the storage space and management costs of the fixture. The end of the connecting rod far from the fixed seat is rotatably connected with a contact frame. There are five contact frames. The multiple connecting rods are symmetrically arranged on the front and back sides of the contact frame. The contact frame is rotatably connected to the positioning rod. The two connecting rods on one side of the contact frame are divided into a group, and the two connecting rods in a group are arranged on both sides of the positioning rod.

[0006] Preferably, the welding assembly includes a square plate. A vertical plate is fixedly connected to the top of the square plate. A fixing ring is fixedly connected to the top of the vertical plate. The side of the fixing ring close to the limiting plate is inclined. A sliding groove is formed on the outer side of the fixing ring. A welding piece is rotatably connected to the inside of the sliding groove. There are two vertical plates, and the two vertical plates are symmetrically arranged with the welding piece as the center. A sliding groove is formed on the inner wall of the fixing ring. There are multiple sliding grooves, and the multiple sliding grooves are evenly distributed with the fixing ring as the center. A slider is slidably connected to the inner wall of the sliding groove. After fixing the workpiece, the moving block drives the fixing assembly and the workpiece to slide on the slide rail in the direction of the welding assembly. Contact is made between the workpiece and the arc plate. The arc plate is stressed to drive the U-shaped plate to move towards the inner wall of the fixing ring along the fixing rod. As the workpiece moves, the slider moves towards the welding piece under the action of the axial force. The workpieces on both sides of the welding assembly move towards the middle, so as to be butt-joined and combined. By setting the slide rail and the moving block, the moving track of the workpieces on both sides can be accurately controlled, so that they are butt-joined according to the preset butt-joint position and angle, reducing the butt-joint deviation and improving the accuracy of the butt-joint. Since the sliding groove is inclined, the arc plate is closer to the workpiece. At this time, the slider drives the arc plate to be in close contact with the welding edge of the workpiece, reducing the gap and the amount of misalignment, so as to ensure that the root of the weld can be completely melted, avoiding defects such as incomplete penetration, porosity, and slag inclusion, and improving the quality and strength of the weld. The two sliders located on both sides of the welding piece are magnetic, and the magnetism between the two sliders is the same. A fixing rod is fixedly connected to the side of the slider away from the sliding groove. A U-shaped plate is slidably connected to the outer side of the fixing rod. A spiral plate is fixedly connected to the bottom of the U-shaped plate. One end of the spiral plate away from the U-shaped plate is fixedly connected to the slider. An arc plate is fixedly connected to the end of the U-shaped plate away from the spiral plate.

The welding head is fixedly connected with a baffle plate on the outer side of the block away from the welding head. The outer side of the baffle plate is fixedly connected with a reset spring. The side of the block close to the welding head is fixedly connected with a limit plate. The limit plate is elastic and is set in an L shape. The side of the limit plate is located inside the guide groove. Through the adaptation between the limit plate and the fixed ring, the adjustment sliding of the welding head is guided so that the welding head is located in the middle of the workpieces on both sides to avoid the welding head from being offset, so that the weld after welding is completed can be in a symmetrical position in the structure, making the connection between the workpieces on both sides more stable and the force more uniform. It can also ensure that the heat is evenly distributed on the workpieces on both sides during welding, so that the degree of fusion of the workpieces on both sides is consistent, avoiding the situation where one side is well fused and the other side is insufficiently fused, thereby improving the quality and strength of the weld. The end of the reset spring away from the baffle is fixedly connected to the limit plate, and the limit plate is symmetrically set with the welding head as the center.

[0008] The present invention provides a correction auxiliary device for steel structure welding, which has the following beneficial effects: 1. This correction auxiliary equipment for steel structure welding can fix the workpiece from different directions and angles through multiple bent plates, disperse the force on the fixed point, and effectively prevent the workpiece from displacement, deformation or shaking due to welding stress during the welding process, ensuring that the workpiece maintains a stable position during welding, providing a basic guarantee for high-quality welding.

[0009] 2. The correction auxiliary equipment for steel structure welding can adjust the angle of the contact frame so that the contact frame can better adapt to the surface shape of the workpiece, achieve a full range of tight fit, reduce the shaking and displacement of the workpiece during the welding process, so as to adapt to workpieces of various shapes and sizes.

[0010] 3. This correction auxiliary equipment for steel structure welding drives the arc plate to be in close contact with the welding edge of the workpiece through the slider, reducing the gap and misalignment, thereby ensuring that the root of the weld can be completely fused, avoiding defects such as incomplete penetration, pores, slag inclusions, and improving the quality and strength of the weld.

[0011] 4. The correction auxiliary equipment for steel structure welding can form a physical barrier on both sides of the welding area close to the workpiece by means of a baffle plate arranged on the outside of the welding head.

[0014] 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 work shall fall within the protection scope of the present invention.

[0015] The first embodiment is as Figures 1 to 6 shown. The present invention provides a technical solution: a calibration auxiliary device for steel structure welding, including a base 1. A slide rail 3 is fixedly connected to the top of the base 1. A moving block 4 is slidably connected to the outside of the slide rail 3, and the number of moving blocks 4 is two; A welding assembly 2 is fixedly installed in the middle of the base 1. The welding assembly 2 penetrates through the base 1. The two moving blocks 4 are symmetrically arranged with the welding assembly 2 as the center; A fixing assembly 5 is fixedly installed in the middle of the moving block 4, and the fixing assembly 5 is arranged parallel to the slide rail 3; Among them, the fixing assembly 5 includes a fixing plate 51. The fixing plate 51 is fixedly installed in the middle of the moving block 4. A motor 52 is fixedly connected to the outside of the fixing plate 51. The output end of the motor 52 is fixedly connected to a gear 53. A circular ring 55 is fixedly connected to the middle of the fixing plate 51. An extension ring 515 is fixedly connected to the inside of the circular ring 55. A ring groove 513 is opened on the outside of the extension ring 515. A through hole 514 is opened on the inner wall of the extension ring 515. A toothed ring 54 is rotatably connected to the outside of the inside of the circular ring 55. Place the workpiece to be processed on the fixing assembly 5 so that the workpiece penetrates through the middle of the extension ring 515. At this time, the motor 52 is powered on to work. The motor 52 drives the gear 53 to rotate, so that the gear 53 drives the toothed ring 54 to rotate. Thus, the toothed ring 54 drives the bent plate 510 to move. At the same time, the round rod 512 slides inside the ring groove 513, so that a plurality of bent plates 510 move towards the workpiece in the middle to clamp the workpiece, keeping the workpiece in the correct relative position during welding, reducing deformation caused by welding stress. By setting a plurality of bent plates 510, the workpiece can be fixed from different directions and angles, dispersing the force on the fixing points, effectively preventing the workpiece from being displaced, deformed or shaken due to the influence of welding stress during the welding process, ensuring that the workpiece maintains a stable position during welding, and providing a basic guarantee for high-quality welding. The toothed ring 54 is symmetrically arranged with the extension ring 515 as the center. One side of the toothed ring 54 close to the extension ring 515 is fixedly connected to a round rod 512. The two ends of the round rod 512 are fixedly connected to the two toothed rings 54. A bent plate 510 is rotatably connected to the outside of the round rod 512. The number of bent plates 510 is multiple, and the multiple bent plates 510 are evenly distributed with the toothed ring 54 as the center. The bent plate 510 penetrates through the extension ring 515 through the through hole 514.

[0016] A rotating rod 58 is rotatably connected to the inner wall of the circular ring 55. There are multiple rotating rods 58, and the multiple rotating rods 58 are evenly distributed around the circular ring 55. The rotating rod 58 is rotatably connected to the outer side of the toothed ring 54. The round rod 512 passes through the extension ring 515 through the ring groove 513. The bent plate 510 is located inside the extension ring 515. One side of the bent plate 510 is fixedly connected with a compression spring 511. By arranging the compression spring 511, the bent plate 510 clamps the workpiece. During the welding process, the workpiece will expand due to heat and contract when cooled. The compression spring can absorb and compensate for this thermal deformation of the welded part to a certain extent, avoid excessive stress generated inside the workpiece due to rigid fixation, and reduce the possibility of welding deformation and crack generation. One end of the bent plate 510 away from the round rod 512 is fixedly connected with a positioning rod 516. One end of the compression spring 511 away from the bent plate 510 is fixedly connected with the extension ring 515. The compression spring 511 is located inside the extension ring 515. A fixed seat 56 is fixedly connected to the inner wall of the toothed ring 54. A connecting rod 57 is rotatably connected to the outer side of the fixed seat 56. There are multiple connecting rods 57. The motor 52 is externally powered to work. The motor 52 drives the gear 53 to rotate when working, so that the gear 53 drives the toothed ring 54 to rotate, and the toothed ring 54 drives the fixed seat 56 to move. Under the connection action of the connecting rod 57, the contact frame 59 rotates around the positioning rod 516, thereby adjusting the angle of the contact frame 59, so that the contact frame 59 can better adapt to the surface shape of the workpiece, achieve all-round close fitting, reduce the shaking and displacement of the workpiece during the welding process, and facilitate adapting to workpieces of various shapes and sizes. This not only reduces the procurement and manufacturing costs of the fixture, but also reduces the storage space and management costs of the fixture. One end of the connecting rod 57 away from the fixed seat 56 is rotatably connected to the contact frame 59. There are five contact frames 59. The multiple connecting rods 57 are symmetrically arranged on the front and back sides of the contact frame 59. The contact frame 59 is rotatably connected to the positioning rod 516. The two connecting rods 57 on one side of the contact frame 59 are divided into a group, and the two connecting rods 57 in a group are arranged on both sides of the positioning rod 516.

[0017] Second embodiment, on the basis of the first embodiment, please refer to Figures 7 to 9As shown, the welding assembly 2 includes a square plate 21. A vertical plate 22 is fixedly connected to the top of the square plate 21. A fixing ring 23 is fixedly connected to the top of the vertical plate 22. The side of the fixing ring 23 close to the limiting plate 248 is inclined. A sliding groove 211 is formed on the outer side of the fixing ring 23. A welding part 24 is rotatably connected inside the sliding groove 211. There are two vertical plates 22, and the two vertical plates 22 are symmetrically arranged with the welding part 24 as the center. A sliding groove 25 is formed on the inner wall of the fixing ring 23. There are multiple sliding grooves 25, and the multiple sliding grooves 25 are evenly distributed with the fixing ring 23 as the center. A slider 26 is slidably connected to the inner wall of the sliding groove 25. After fixing the workpiece, the moving block 4 drives the fixing assembly 5 and the workpiece to slide on the slide rail 3 towards the welding assembly 2. The workpiece contacts with the arc plate 29. The arc plate 29 is stressed to drive the U-shaped plate 28 to move towards the inner wall of the fixing ring 23 along the fixing rod 210. As the workpiece moves, under the action of the axial force, the slider 26 moves towards the welding part 24. The workpieces on both sides of the welding assembly 2 move towards the middle, so as to be butted and combined. By setting the slide rail 3 and the moving block 4, the moving trajectories of the workpieces on both sides can be accurately controlled, so that they are butted according to the preset butting position and angle, reducing the butting deviation and improving the butting accuracy. Since the sliding groove 25 is inclined, the arc plate 29 is closer to the workpiece. At this time, the slider 26 drives the arc plate 29 to be in close contact with the welding edge of the workpiece, reducing the gap and the amount of misalignment, so as to ensure that the root of the weld can be completely fused, avoiding defects such as incomplete penetration, porosity, and slag inclusion, and improving the quality and strength of the weld. The two sliders 26 located on both sides of the welding part 24 have magnetism, and the magnetism between the two sliders 26 is the same. A fixing rod 210 is fixedly connected to the side of the slider 26 away from the sliding groove 25. The fixing rod 210 is slidably connected to the outside of the U-shaped plate 28. A spiral plate 27 is fixedly connected to the bottom of the U-shaped plate 28. One end of the spiral plate 27 away from the U-shaped plate 28 is fixedly connected to the slider 26. An arc plate 29 is fixedly connected to the end of the U-shaped plate 28 away from the spiral plate 27.

[0018] The third embodiment is based on the first and second embodiments. Please refer to Figure 10As shown, the welded part 24 includes a limit ring 241. A square block 242 is fixedly connected to the outer side of the limit ring 241. The number of square blocks 242 is two, and the two square blocks 242 are evenly distributed around the limit ring 241. A roller 243 is rotatably connected to one end of the square block 242 close to the fixed ring 23. The roller 243 is located inside the sliding groove 211. The square block 242 and the fixed ring 23 are rotatably connected through the roller 243 and the sliding groove 211. After the two workpiece sides are butted and fixed, using the elastic property of the return spring 246, the welding head 244 contacts the welding position. Subsequently, the roller 243 rotates inside the sliding groove 211. Thus, the roller 243 drives the welding head 244 through the limit ring 241 and the square block 242 to weld the workpiece. By means of the baffle 247 provided on the outer side of the welding head 244, a physical barrier can be formed on both sides of the welding area close to the workpiece. When the spatter generated during welding sprays outwards, the baffle 247 can directly block the flight path of the spatter, preventing it from scattering everywhere, thereby reducing the impact of the spatter on the surrounding environment, equipment, and operators. A welding head 244 is slidably connected to the middle of the square block 242. A guiding groove 245 is provided on the outer side of the welding head 244. The welding head 244 penetrates through the square block 242. A baffle 247 is fixedly connected to the outer side of the welding head 244 away from the square block 242. A return spring 246 is fixedly connected to the outer side of the baffle 247. A limiting plate 248 is fixedly connected to one side of the square block 242 close to the welding head 244. The limiting plate 248 has elasticity. The limiting plate 248 is L-shaped, and the side of the limiting plate 248 is located inside the guiding groove 245. Through the adaptation between the limiting plate 248 and the fixed ring 23, the adjustment sliding of the welding head 244 is guided, so that the welding head 244 is located in the middle of the two workpiece sides, preventing the welding head 244 from shifting. Thus, the weld after welding can be symmetrically positioned structurally, making the connection of the two workpiece sides more stable and the force more evenly distributed. It can also ensure that the heat is evenly distributed on the two workpiece sides during welding, making the fusion degree of the two workpiece sides consistent, avoiding the situation where one side fuses well while the other side fuses insufficiently, thereby improving the quality and strength of the weld. The end of the return spring 246 away from the baffle 247 is fixedly connected to the limiting plate 248. The limiting plates 248 are symmetrically arranged around the welding head 244.

[0019] During use, the workpiece to be processed is placed on the fixing assembly 5, such that the workpiece penetrates through the middle of the extension ring 515. At this time, the motor 52 is externally powered and operates. The motor 52 drives the gear 53 to rotate, causing the gear 53 to drive the toothed ring 54 to rotate. Thus, the toothed ring 54 drives the bent plate 510 to move. At the same time, the round rod 512 slides inside the ring groove 513, causing multiple bent plates 510 to move towards the workpiece in the middle to clamp the workpiece.

[0020] The moving block 4 drives the fixed component 5 and the workpiece to slide on the slide rail 3 towards the welding component 2. The workpiece contacts the arc plate 29. The arc plate 29 is stressed and drives the U-shaped plate 28 to move towards the inner wall of the fixed ring 23 on the fixed rod 210. As the workpiece moves, the slider 26 moves towards the welding part 24 under the action of the axial force. The workpieces on both sides of the welding component 2 move towards the middle, so as to be butt-joined and combined.

[0021] After the workpieces on both sides are butt-joined and fixed, by utilizing the elastic performance of the return spring 246, the welding head 244 contacts the welding place. Subsequently, the roller 243 rotates inside the sliding groove 211. Thus, the roller 243 drives the welding head 244 through the limiting ring 241 and the square block 242 to weld the workpiece.
