Description

Technical Field

[0001] The invention relates to the technical field of steel structure welding, in particular to correction auxiliary equipment for steel structure welding. Background Art

[0002] With the rapid development of the economy, my country's infrastructure construction is developing at an increasingly rapid pace. In infrastructure construction, a large number of steel structures are used. Steel structures are made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings and other fields.

[0003] When existing steel structures are used, they need to be welded. Steel pipes are a type of steel structure. During welding, the workpieces cannot be well fixed, and the workpieces on both sides are easily misaligned, which affects the welding effect. In addition, the welding position cannot be fully welded. If the steel pipes are manually transmitted during welding, it is easy to cause the two steel pipes to be misaligned, affecting the welding. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A correction auxiliary device for steel structure welding, comprising a base, a slide rail fixedly connected to the top of the base, a moving block slidably connected to the outer side of the slide rail, and two moving blocks;

[0005] The welding assembly is fixedly installed in the middle of the base, the welding assembly passes through the base, and the two moving blocks are symmetrically arranged with the welding assembly as the center;

[0006] A fixed component is fixedly installed in the middle of the slider and is arranged parallel to the slide rail;

[0007] The fixing assembly includes a fixing plate, which is fixedly mounted in the middle of the moving block, a motor is fixedly connected to the outside of the fixing plate, a gear is fixedly connected to the output end of the motor, a circular ring is fixedly connected to the middle of the fixing plate, an extension ring is fixedly connected to the inside of the circular ring, a ring groove is provided on the outside of the extension ring, a through hole is provided on the inner wall of the extension ring, and a gear ring is rotatably connected to the inner and outer sides of the circular ring. The workpiece to be processed is placed on the fixing assembly so that the workpiece passes through the middle of the extension ring. At this time, the motor is connected to an external power supply and the motor drives the gear to rotate, so that the gear drives the gear ring to rotate, and the gear 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 toward the workpiece in the middle, thereby machining the workpiece. The workpiece is clamped in a fixed position during welding to reduce deformation caused by welding stress. By setting up multiple bent plates, the workpiece can be fixed from different directions and angles, dispersing the force on the fixed point, and effectively preventing the workpiece from being displaced, deformed or shaken due to the influence of welding stress during welding. This ensures that the workpiece maintains a stable position during welding, providing a basic guarantee for high-quality welding. The gear ring is symmetrically arranged with the extension ring as the center. A round rod is fixedly connected to the side of the gear ring close to the extension ring. The two ends of the round rod are fixedly connected to the two gear rings. The outer side of the round rod is rotatably connected to a bent plate. There are multiple bent plates, and the multiple bent plates are evenly distributed with the gear ring as the center. The bent plate passes through the extension ring through a through hole.

[0008] Preferably, the inner wall of the circular ring is rotatably connected with a rotating rod, and the number of rotating rods is multiple, and the multiple rotating rods are evenly distributed with the circular ring as the center, and the rotating rod is rotatably connected to the outer side of the gear ring, the circular rod passes through the extension ring through the ring groove, the bent plate is located inside the extension ring, and 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 cooling. The compression spring can absorb and compensate for this thermal deformation of the weld to a certain extent, avoiding excessive stress inside the workpiece due to rigid fixation, reducing the possibility of welding deformation and cracks, and the end of the bent plate away from the circular rod is fixedly connected to the positioning rod, and the end of the compression spring away from the bent plate is fixedly connected to the extension ring. The compression spring is located inside the extension ring, the inner wall of the gear ring is fixedly connected with a fixed seat, and the outer side of the fixed seat is rotatably connected with Connecting rod, there are multiple connecting rods, the motor is connected to an external power supply, the motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring drives the fixed seat to move. Under the connecting action of the connecting rod, the contact frame rotates around the positioning rod, and then adjusts the angle of the contact frame, so that the contact frame can better adapt to the surface shape of the workpiece, achieve all-round tight fit, reduce the shaking and displacement of the workpiece during welding, so as to adapt to workpieces of various shapes and sizes, which 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 away from the fixed seat is rotatably connected to the contact frame. There are five contact frames, and 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.

[0009] The top of the fixing plate is fixedly connected to the vertical plate, and the top of the fixing plate is fixedly connected to the fixing ring. The fixing ring is inclined near the limit plate, and a sliding groove is provided on the outer side of the fixing ring. The welding piece is rotatably connected inside the sliding groove. There are two vertical plates, and the two vertical plates are symmetrically arranged with the welding piece as the center. The inner wall of the fixing ring is provided with a sliding groove, and the number of the sliding grooves is multiple, and the multiple sliding grooves are evenly distributed with the fixing ring as the center. The inner wall of the sliding groove is slidably connected with a slider. After the workpiece is fixed, the moving block drives the fixing assembly and the workpiece to slide on the slide rail toward the direction of the welding assembly. The workpiece contacts the arc plate, and the arc plate is subjected to force to drive the U-shaped plate to move on the fixing rod toward the inner wall of the fixing ring. As the workpiece moves, the slider moves toward the direction of the welding piece under the action of the axial force, and the workpieces on both sides of the welding assembly move toward the middle, from The docking and merging can precisely control the moving trajectory of the workpieces on both sides by setting slide rails and moving blocks, so that they can be docked according to the preset docking position and angle, reducing docking deviation and improving docking accuracy. Since the slide is inclined, the arc plate is closer to the workpiece. At this time, the slider drives the arc plate to make close contact with the welding edge of the workpiece, reducing the gap and misalignment, thereby ensuring that the root of the weld can be completely fused, avoiding defects such as incomplete welding, air holes, slag inclusions, and improving the quality and strength of the weld. The two sliders on both sides of the weld are magnetic, and the magnetism between the two sliders is the same. The side of the slider away from the slide is fixedly connected to a fixed rod, and the outer side of the fixed rod is slidably connected to a U-shaped plate. The bottom of the U-shaped plate is fixedly connected to a spiral plate, and the end of the spiral plate away from the U-shaped plate is fixedly connected to the slider, and the end of the U-shaped plate away from the spiral plate is fixedly connected to the arc plate.

[0010] Preferably, the welding part includes a limiting ring, and a block is fixedly connected to the outside of the limiting ring. There are two blocks, and the two blocks are evenly distributed with the limiting ring as the center. The block is rotatably connected to a roller at one end close to the fixing ring, and the roller is located inside the sliding groove. The block and the fixing ring are rotatably connected to the sliding groove through the roller. After the workpieces on both sides are docked and fixed, the elastic performance of the return spring is utilized to make the welding head contact with the welding point, and then the roller rotates inside the sliding groove, so that the roller drives the welding head to weld the workpiece through the limiting ring and the block. By arranging a baffle on the outside of the welding head, a physical barrier can be formed on both sides of the welding area close to the workpiece. When the spatter generated by welding is ejected outward, the baffle can directly block the flight path of the spatter, so that it cannot be scattered everywhere, thereby reducing the impact of the spatter on the surrounding environment, equipment and operators. The middle part of the block is slidably connected to the welding head, and the outside of the welding head is provided with The guide groove and the welding head pass through the block, and the welding head is fixedly connected to a baffle on the outside of the block away from the welding head. The outside of the baffle is fixedly connected to a reset spring, and the side of the block close to the welding head is fixedly connected to a limit plate. The limit plate is elastic, the limit plate is L-shaped, and 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, avoiding the welding head from being offset, so that the weld after welding is completed is in a structurally symmetrical position, making the connection between the workpieces on both sides more stable and the force more uniform, and also ensuring 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, and the end of the reset spring away from the baffle is fixedly connected to the limit plate, and the limit plate is symmetrically arranged with the welding head as the center.

[0011] The present invention provides a correction auxiliary device for steel structure welding. It has the following beneficial effects:

[0012] 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 the influence of welding stress during the welding process, ensuring that the workpiece maintains a stable position during welding, providing a basic guarantee for high-quality welding.

[0013] 2.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The first embodiment, as Figures 1 to 6 As shown, the present invention provides a technical solution: a correction auxiliary device for steel structure welding, comprising a base 1, a slide rail 3 is fixedly connected to the top of the base 1, and a moving block 4 is slidably connected to the outer side of the slide rail 3, and the number of the moving blocks 4 is two;

[0029] The welding assembly 2 is fixedly mounted in the middle of the base 1 and passes through the base 1. The two moving blocks 4 are symmetrically arranged with the welding assembly 2 as the center.

[0030] The fixed component 5 is fixedly mounted on the middle part of the moving block 4 and is arranged parallel to the slide rail 3;

[0031] Among them, the fixed component 5 includes a fixed plate 51, which is fixedly installed in the middle of the moving block 4, and a motor 52 is fixedly connected to the outer side of the fixed plate 51, and a gear 53 is fixedly connected to the output end of the motor 52. A circular ring 55 is fixedly connected to the middle of the fixed plate 51, and an extension ring 515 is fixedly connected to the inside of the circular ring 55. A ring groove 513 is provided on the outer side of the extension ring 515, and a through hole 514 is provided on the inner wall of the extension ring 515. The inner and outer sides of the circular ring 55 are rotatably connected to the gear ring 54. The workpiece to be processed is placed on the fixed component 5 so that the workpiece passes through the middle of the extension ring 515. At this time, the motor 52 is connected to an external power supply and works, and the motor 52 drives the gear 53 to rotate, so that the gear 53 drives the gear ring 54 to rotate, so that the gear ring 54 drives the bent plate 510 to move, and at the same time the round rod 512 slides inside the ring groove 513, so that multiple bent plates 510 move toward the center. The workpiece moves and is clamped to keep the workpiece in the correct relative position during welding, reducing deformation caused by welding stress. By setting up multiple bent plates 510, the workpiece can be fixed from different directions and angles, and the force on the fixed point can be dispersed, effectively preventing the workpiece from being displaced, deformed or shaking due to the influence of welding stress during welding, ensuring that the workpiece maintains a stable position during welding, and providing a basic guarantee for high-quality welding. The gear ring 54 is symmetrically arranged with the extension ring 515 as the center. The side of the gear ring 54 close to the extension ring 515 is fixedly connected to the round rod 512, and the two ends of the round rod 512 are fixedly connected to the two gear rings 54. The outer side of the round rod 512 is rotatably connected. There are multiple bent plates 510, and the multiple bent plates 510 are evenly distributed with the gear ring 54 as the center.

The bent plate 510 is located inside the extension ring 515. A compression spring 511 is fixedly connected to one side of the bent plate 510. By setting the compression spring 511, the bent plate 510 clamps the workpiece. During the welding process, the workpiece will expand due to heat. When cooling, the workpiece will expand. The compression spring can absorb and compensate for the thermal deformation of the weldment to a certain extent, avoid excessive stress inside the workpiece due to rigid fixation, and reduce the possibility of welding deformation and cracks. The end of the bent plate 510 away from the round rod 512 is fixedly connected to the positioning rod 516, and the end of the compression spring 511 away from the bent plate 510 is fixedly connected to the extension ring 515. The compression spring 511 is located inside the extension ring 515. The inner wall of the gear ring 54 is fixedly connected to the fixing seat 56. The outer wall of the fixing seat 56 The side is rotatably connected with a connecting rod 57, and there are multiple connecting rods 57. The motor 52 is connected to an external power supply to work. The motor 52 drives the gear 53 to rotate, so that the gear 53 drives the gear ring 54 to rotate, and the gear 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 tight fit, reduce the shaking and displacement of the workpiece during welding, so as to adapt 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 57 away from the fixed seat 56 is rotatably connected to the contact frame 59. There are five contact frames 59, and multiple connecting rods 57 are symmetrically arranged on the front and rear 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.

[0033] The second embodiment, based on the first embodiment, see 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 fixing ring 23 is inclined on one side close to the limit plate 248, a sliding groove 211 is provided on the outside of the fixing ring 23, and a welding piece 24 is rotatably connected to the inside of the sliding groove 211. There are two vertical plates 22, and the two vertical plates 22 are symmetrically arranged with the welding piece 24 as the center. The inner wall of the fixing ring 23 is provided with a sliding groove 25. The number of the sliding grooves 25 is as follows: There are multiple, multiple slide grooves 25 evenly distributed with the fixed ring 23 as the center, and the inner wall of the slide groove 25 is slidably connected with a slider 26. After the workpiece is fixed, the moving block 4 drives the fixed component 5 and the workpiece to slide on the slide rail 3 toward the welding component 2. The workpiece contacts the arc plate 29, and the arc plate 29 is forced to drive the U-shaped plate 28 to move toward the inner wall of the fixed ring 23 on the fixed rod 210. As the workpiece moves, the slider 26 moves toward the welding part 24 under the action of the axial force, and the two sides of the welding component 2 are welded. The side workpieces move toward the middle, thereby docking and merging. By setting the slide rail 3 and the moving block 4, the moving trajectory of the workpieces on both sides can be accurately controlled so that they can be docked according to the preset docking position and angle, reducing docking deviation and improving docking accuracy. Since the slide 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 closely contact the welding edge of the workpiece, reducing the gap and misalignment, thereby ensuring that the root of the weld can be completely fused, avoiding defects such as incomplete welding, air holes, slag inclusions, etc., and improving the quality and strength of the weld. The two sliders 26 located on both sides of the welding part 24 are magnetic, and the magnetism between the two sliders 26 is the same. The side of the slider 26 away from the slide groove 25 is fixedly connected to the fixed rod 210, and the outer side of the fixed rod 210 is slidably connected to the U-shaped plate 28.

The end of the spiral plate 27 away from the U-shaped plate 28 is fixedly connected to the slider 26, and the end of the U-shaped plate 28 away from the spiral plate 27 is fixedly connected to the arc plate 29.

[0034] The third embodiment, based on the first and second embodiments, see Figure 10As shown, the welding part 24 includes a limiting ring 241, and a block 242 is fixedly connected to the outer side of the limiting ring 241. There are two blocks 242, and the two blocks 242 are evenly distributed with the limiting ring 241 as the center. The end of the block 242 close to the fixed ring 23 is rotatably connected to the roller 243, and the roller 243 is located inside the sliding groove 211. The block 242 and the fixed ring 23 are rotatably connected to the sliding groove 211 through the roller 243. After the workpieces on both sides are docked and fixed, the elastic performance of the reset spring 246 is used to make the welding head 244 contact with the welding point, and then the roller 24 The roller 243 rotates inside the sliding groove 211, thereby driving the welding head 244 to weld the workpiece through the limiting ring 241 and the block 242. The baffle 247 provided on the outside of the welding head 244 can form a physical barrier on both sides of the welding area close to the workpiece. When the spatter generated by welding is ejected outward, 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. The middle part of the block 242 is slidably connected to the welding head 244. The welding head 244 A guide groove 245 is provided on the outside of the block 242, and the welding head 244 is fixedly connected to the outside of the block 242 with a baffle 247, and a return spring 246 is fixedly connected to the outside of the baffle 247. The side of the block 242 close to the welding head 244 is fixedly connected to a limit plate 248. The limit plate 248 is elastic, and the limit plate 248 is L-shaped. The side of the limit plate 248 is located inside the guide groove 245. The adjustment sliding of the welding head 244 is guided by the adaptation between the limit plate 248 and the fixing ring 23, so that the welding The head 244 is located in the middle of the workpieces on both sides to avoid the welding head 244 from being offset, so that the weld after welding is completed is in a structurally symmetrical position, 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 246 away from the baffle 247 is fixedly connected to the limit plate 248, and the limit plate 248 is symmetrically arranged with the welding head 244 as the center.

[0035] During use, the workpiece to be processed is placed on the fixed component 5 so that the workpiece passes through the middle of the extension ring 515. At this time, the motor 52 is connected to the external power supply and drives the gear 53 to rotate, so that the gear 53 drives the gear ring 54 to rotate, and the gear 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 multiple bent plates 510 move toward the middle of the workpiece to clamp the workpiece.

[0036] The moving block 4 drives the fixed assembly 5 and the workpiece to slide on the slide rail 3 toward the welding assembly 2. The workpiece contacts the arc plate 29. The arc plate 29 is forced to drive the U-shaped plate 28 to move toward the inner wall of the fixed ring 23 on the fixed rod 210. As the workpiece moves, the slider 26 moves toward the welding part 24 under the action of the axial force, and the workpieces on both sides of the welding assembly 2 move toward the middle, thereby docking and merging.

[0037] After the workpieces on both sides are docked and fixed, the welding head 244 contacts the welding point by utilizing the elastic performance of the reset spring 246, and then the roller 243 rotates inside the sliding groove 211, so that the roller 243 drives the welding head 244 to weld the workpieces through the limiting ring 241 and the block 242.
