Description

TECHNICAL FIELD

[0001] The present application relates to the field of C-shaped steel welding equipment, in particular to a C-shaped steel automatic alignment welding equipment. BACKGROUND

[0002] As a common building and industrial material, the automatic welding technology of C-shaped steel has important significance in improving production efficiency and ensuring product quality. C-shaped steel is also commonly used in nuclear power bridge, and the special double C-shaped steel for nuclear power bridge is composed of two symmetrical C-shaped steels combined together by welding or other connecting methods, forming a whole bridge structure. This structure has high strength and stability, and can bear the weight of the cable bridge and various external forces that may be received.

[0003] During the welding process of the special double C-shaped steel for nuclear power bridge, the welding gun moves on the C-shaped steel, first welding the welding surfaces of one side of the two C-shaped steels into one, then turning over the C-shaped steel, and welding the welding surfaces of the other side of the two C-shaped steels into one. Due to the inconsistent welding time of the two welding surfaces, the two steel bodies are not heated uniformly, which is easy to produce stress, so that the double C-shaped steel after welding cannot release the internal stress and is easy to deform. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to overcome the above technical problems, and provide a C-shaped steel automatic alignment welding equipment.

[0005] A C-shaped steel automatic alignment welding equipment, comprising:

[0006] A workbench comprising a welding part and a sliding part;

[0007] A moving mechanism located on the surface of the sliding part, the moving mechanism comprising a clamping piece and a driving piece, the clamping piece being used to clamp two C-shaped steel workpieces that have been buckled, and the driving piece being used to drive the clamping piece to move;

[0008] A limiting mechanism located on the surface of the welding part, the limiting mechanism comprising two groups of guide rollers, the two groups of guide rollers being respectively arranged on the two sides of the clamping piece and being used to abut against the two buckled C-shaped steel workpieces, and

[0009] A welding mechanism located on the surface of the workbench, the welding mechanism comprising two welding guns, the two welding guns being respectively used to weld the two sides of the contact surface of the two buckled C-shaped steels.

[0010] By adopting the above solution, the inconsistent welding times on the two sides of the C-shaped steel during welding lead to uneven heating of the two steel bodies, which easily generates stress. This prevents the internal stress of the welded double C-shaped steel from being released, resulting in deformation. By setting up a limiting mechanism and a welding mechanism, the limiting mechanism limits the C-shaped steel, making the welding position of the welding torch more precise. Two symmetrically set welding torches weld the C-shaped steel simultaneously, avoiding inconsistent welding times of the steel bodies and improving work efficiency.

[0011] In one embodiment, the sliding part is provided with a slide rail, and the clamping member is supported on the slide rail and slides along the slide rail.

[0012] By adopting the above solution and setting the slide rail, the clamping component can slide under the drive of the driving component.

[0013] In one embodiment, the clamping member includes a clamping rod, an abutment rod, and a drive seat. The drive seat carries the clamping rod and cooperates with the slide rail. One end of the abutment rod is connected to the clamping rod, and the other end is connected to the drive seat. The abutment rod is inclined, and the drive member is located on one side of the drive seat.

[0014] By adopting the above solution, a triangular structure is formed between the clamping rod abutment rod and the drive seat, which prevents the clamping rod from shaking during the clamping of the C-shaped steel, thus avoiding inaccurate welding position of the C-shaped steel.

[0015] In one embodiment, the limiting mechanism further includes a limiting roller, a sliding roller, and a support frame. The support frame is U-shaped and fixed to the surface of the worktable. The limiting roller is supported by the support frame. The sliding roller is located on the surface of the worktable. The sliding roller is parallel to the limiting roller and both are located on the same vertical plane.

[0016] By adopting the above scheme, a grid-like structure is formed between the limiting roller, the guide roller, and the sliding roller, which simultaneously limits the C-shaped steel to prevent the position of the C-shaped steel from changing during the movement, thus preventing inaccurate welding position.

[0017] In one embodiment, the support frame is provided with a sliding plate that moves in the vertical direction, the limiting roller is fixed to the sliding plate, the limiting mechanism further includes a support seat, a plurality of the guide rollers are supported on the support seat, the support seats are symmetrically distributed with respect to the symmetry plane of the support frame, and the support seats can slide in a direction perpendicular to the slide rail.

[0018] By adopting the above scheme, and by setting up sliding plates and bearing seats, the positions of the limiting rollers and guide rollers can be adjusted, which can be adapted to C-shaped steel of different sizes.

[0019] In one embodiment, the welding mechanism further includes an adjustment seat, which includes a drive shaft and an adjustment rod. One end of the adjustment rod is fixed to the drive shaft, and the other end is fixed to the welding torch. The drive shaft drives the adjustment rod to rotate in a vertical plane parallel to the slide rail.

[0020] By adopting the above solution, the height of the welding torch can be controlled by driving the adjusting rod to rotate through the driving shaft, thereby enabling the nozzle of the welding torch to be more accurately aligned with the welding point of the C-shaped steel.

[0021] In one embodiment, a limiting plate is fixed on the side of the adjusting rod away from the drive shaft, and an adjusting rail perpendicular to the slide rail is provided on the upper surface of the worktable, with the adjusting seat cooperating with the adjusting rail.

[0022] By adopting the above scheme, before welding, the drive shaft drives the welding torch to rotate, so that the welding torch is located at the bottom of the C-shaped steel. The adjustment table moves towards the C-shaped steel, so that the limiting plate abuts against the welding point of the C-shaped steel, keeping the welding point of the C-shaped steel flat, thereby initially limiting the C-shaped steel. After the C-shaped steel is limited, the drive shaft drives the welding torch to rotate, so that the nozzle of the welding torch is aligned with the welding point.

[0023] In one embodiment, the adjusting rod includes a connecting portion and a telescopic portion perpendicular to the connecting portion. One end of the telescopic portion opposite to the connecting portion is fixed to the drive shaft, and the other end of the connecting portion opposite to the telescopic portion is fixed to the welding torch. The length of the telescopic portion is adjustable.

[0024] By adopting the above solution, the rotation radius of the welding torch driven by the adjusting rod can be controlled, further enhancing the flexibility of the welding torch and enabling the welding torch to adjust the nozzle position within a wider range, thereby adapting to different application scenarios.

[0025] In one embodiment, the welding torch is bent, and the adjusting rod and the nozzle of the welding torch are located on opposite sides of the limiting plate.

[0026] By adopting the above solution, it is possible to prevent sparks from flying during the welding process, which may ignite surrounding combustibles and burn workers. By setting the position of the welding gun and the limiting plate, the limiting plate can block the sparks during the welding process and prevent them from flying.

[0027] In one embodiment, the welding mechanism is provided with an exhaust gas suction pipe at its top.

[0028] By adopting the above solution, the exhaust gas suction pipe can absorb the exhaust gas generated during the welding process, preventing the exhaust gas from polluting the working environment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. During the welding of C-shaped steel, the welding time on the two sides of the steel body is inconsistent, resulting in uneven heating of the two steel bodies. This easily generates stress, preventing the internal stress of the welded double C-shaped steel from being released, thus causing deformation. By setting up a limiting mechanism and a welding mechanism, the limiting mechanism limits the C-shaped steel, making the welding position of the welding torch more precise. Two symmetrically set welding torches weld the C-shaped steel simultaneously, avoiding inconsistent welding time of the steel bodies and improving work efficiency.

[0031] 2. By setting guide rollers, limit rollers, and sliding rollers, a grid structure is formed between the limit rollers, guide rollers, and sliding rollers, which simultaneously limits the C-shaped steel and prevents the position of the C-shaped steel from changing during the movement, thus preventing inaccurate welding position. The positions of the limit rollers, guide rollers, and sliding rollers are all adjustable to accommodate C-shaped steel of different sizes.

[0032] 3. By adjusting the base, the drive shaft rotates the adjusting rod, controlling the height of the welding torch. This allows the nozzle of the welding torch to be more precisely aligned with the welding point of the C-shaped steel. Before welding, the drive shaft rotates the welding torch, positioning it at the bottom of the C-shaped steel. The adjusting table moves towards the C-shaped steel, bringing the limiting plate into contact with the welding point of the C-shaped steel, ensuring the welding point remains flat and thus initially limiting the C-shaped steel. Once the C-shaped steel is limited, the drive shaft rotates the welding torch, aligning the nozzle with the welding point. The limiting plate is located between the nozzle of the welding torch and the adjusting rod, thus blocking sparks and preventing them from splashing. Attached Figure Description

[0039] Therefore, it is necessary to provide an automatic alignment welding equipment for C-shaped steel that can weld accurately.

[0040] Please see Figure 1 , Figure 1 The present application provides a structural schematic diagram of an automatic alignment and welding equipment for C-shaped steel, which includes a worktable 1, a moving mechanism 4, a limiting mechanism 2, and a welding mechanism 3.

[0041] Please refer to the following: Figure 2 , Figure 2 The diagram shows the structure of the limiting mechanism 2, which is located on the surface of the worktable 1. The limiting mechanism 2 includes a guide roller 21 and a support seat 25. The guide roller 21 and the support seat 25 are symmetrically arranged on both sides of the worktable 1. The direction in which the guide roller 21 extends is perpendicular to the surface of the worktable 1. The guide roller 21 can be made of metal materials, such as stainless steel or aluminum alloy, to ensure its structural strength and wear resistance. The surface of the guide roller 21 can be polished to reduce the friction between it and the C-shaped steel 6. The guide roller 21 can be mounted on the support seat 25 through bearings to ensure that it can rotate flexibly, thereby guiding the C-shaped steel 6 to move along a predetermined path. Multiple guide rollers 21 can be set on the support seat 25 to limit the C-shaped steel 6 at multiple points. A lead screw can be inserted through the bottom of the support seat 25, or a track sliding form can be used to achieve sliding in a direction perpendicular to the C-shaped steel 6, thereby adapting to C-shaped steel 6 of different widths. The number of guide rollers 21 can be adjusted according to actual needs. For example, it can be set to two or more sets, each set containing multiple guide rollers 21, to enhance the limiting effect. In actual use, the two sets of guide rollers 21 arranged symmetrically abut against the joint of the two C-shaped steels 6, thereby keeping the weld joint of the two C-shaped steels 6 flat during the welding process.

[0042] In this application, the workbench 1 includes a welding part 11 and a sliding part 12. The limiting mechanism 2 also includes a limiting roller 22, a sliding roller 23, and a support frame 24. The support frame 24 is U-shaped and is fixed to the surface of the welding part 11 of the workbench 1 by welding. The support frame 24 can be made of cast iron or steel plate to ensure its structural strength and rigidity. The limiting roller 22 is supported on the support frame 24. The support frame 24 has sliding rails on both sides. The support frame 24 also includes a sliding plate 241. The limiting roller 22 is installed at the bottom of the sliding plate 241. The sliding plate 241 can slide along the sliding rails on both sides of the support frame 24. The top of the sliding plate 241 is connected to a hydraulic rod to control the sliding plate 241 to move in the vertical direction, so that the limiting roller 22 can cooperate with C-shaped steel 6 of different sizes. The sliding roller 23 includes multiple rollers and is located on the surface of the welding part 11 of the workbench 1. It is used to support the C-shaped steel 6. The sliding roller 23 is parallel to the limiting roller 22 and is located on the same vertical plane. The limiting roller 22, guide roller 21, and sliding roller 23 form a grid-like structure, which can limit the C-shaped steel 6 in all directions, further improving the accuracy of the welding position.

[0043] Please refer to the following: Figures 3-4 , Figure 3 The diagram shows the structure of the clamping component. The moving mechanism 4 includes a clamping component 41 and a driving component 42. The clamping component 41 is supported on the sliding part 12 and is used to clamp the C-shaped steel 6 and move it. The clamping component 41 includes a clamping rod 411, an abutting rod 412, and a driving seat 413. The driving seat 413 supports the clamping rod 411 and cooperates with the slide rail 121. One end of the abutting rod 412 is connected to the clamping rod 411, and the other end is connected to the driving seat 413. The abutting rod 412 is inclined. This design forms a triangular structure, which enhances the stability of the clamping rod 411 and prevents the C-shaped steel 6 from shaking during welding. The abutting rod 412 can be a hydraulic rod. The end of the clamping rod 411 that clamps the C-shaped steel 6 has a U-shaped opening, and the pressing block 4111 is rotatably connected to the abutting rod 412 inside. The hydraulic rod can control the movement of the pressing block 4111 by extension and retraction, thereby controlling the clamping force of the clamping rod 411. The clamping rod 411 can be made of high-strength steel to withstand greater clamping force; the surface of the clamping rod 411 can be provided with anti-slip texture or rubber pads to increase the friction between it and the C-shaped steel 6; the length of the clamping rod 411 can be adjusted according to actual needs, for example, by means of telescopic rod or segmented splicing.

[0044] The surface of the sliding part 12 is provided with a slide rail 121 that mates with the drive seat 413. The drive seat 413 can be made of cast iron or aluminum alloy to ensure its structural strength and wear resistance. The bottom of the drive seat 413 is provided with balls or sliders to reduce the friction between it and the slide rail 121. The drive seat 413 is in the shape of a boss and has mounting holes or slots on its side for fixing the clamping rod 411. A drive member 42 is provided on the side of the drive seat 413 to make the drive seat 413 slide along the slide rail 121. The drive member 42 can be a motor and slides along the extension direction of the slide rail 121. The clamping rod 411 clamps the C-shaped steel 6, thereby driving the C-shaped steel to move. The clamping rod 411 abuts against the rod 412 and the drive seat 413 to form a triangular structure to prevent the clamping rod 411 from shaking during the clamping of the C-shaped steel 6, which would lead to inaccurate welding position of the C-shaped steel 6.

[0045] Please refer to the following: Figure 5 , Figure 5 The diagram illustrates the welding mechanism 3, which includes an adjusting seat 32 and a welding torch 31. The main body of the welding torch 31 can be made of a high-temperature resistant material, such as nickel-chromium alloy, to withstand the high-temperature environment during welding. The connecting part 3221 of the welding torch 31 can be threaded or quick-release connected for easy maintenance and replacement. Furthermore, the welding torch 31 can be equipped with a cooling device, such as a water-cooled jacket or an air-cooled system, to prevent overheating during prolonged operation. The adjusting seat 32 includes a drive shaft 321 and an adjusting rod 322. One end of the adjusting rod 322 is fixed to the drive shaft 321, and the other end is fixed to the welding torch 31. The drive shaft 321 can be made of steel to ensure its structural strength and rigidity. One end of the drive shaft 321 can be connected to a motor via a coupling, and the other end is fixedly connected to the adjusting rod 322. When the motor starts, the drive shaft 321 drives the adjusting rod 322 to rotate in the vertical plane containing the side of the C-shaped steel 6, thereby changing the height of the nozzle of the welding torch 31. The surface of the drive shaft 321 may be provided with keyways or splines to transmit torque. In addition, the drive shaft 321 may be equipped with an encoder or sensor to detect its rotation angle, thereby achieving precise control of the height of the welding torch 31 nozzle.

[0046] The adjusting rod 322 can be made of steel or aluminum alloy to ensure its structural strength and rigidity. The adjusting rod 322 includes a connecting part 3221 and a telescopic part 3222. The end of the telescopic part 3222 opposite to the connecting part 3221 is fixed to the drive shaft 321. The end of the connecting part 3221 opposite to the telescopic part 3222 is clamped and fixed to the welding torch 31 by bolts and nuts. The telescopic part 3222 is a telescopic rod with an adjustable length. The end of the telescopic part 3222 opposite to the drive shaft 321 can be welded to the connecting part 3221 to form an integral structure, or it can be fixedly connected by a clamp. Operators can control the range of rotation by adjusting the length of the telescopic part 3222, thereby adjusting the position of the welding torch 31 nozzle over a wider range. A limiting plate 323 is fixed on the side of the adjusting rod 322 away from the drive shaft 321. The limiting plate 323 is fixed to the telescopic rod by welding. The welding gun 31 is bent. The nozzle of the welding gun 31 and the adjusting rod 322 are located on both sides of the limiting plate 323 respectively. The top of the welding mechanism 3 is equipped with a waste gas suction pipe 5, which can absorb the waste gas generated during the welding process and prevent the waste gas from polluting the working environment.

[0047] The working principle of this application is as follows: The operator starts the motor, causing the drive shaft 321 to rotate, which rotates the limiting plate 323 to the position opposite to the joint of the two C-shaped steels 6. The driving adjustment seat 32 moves towards the C-shaped steel 6, so that the limiting plate 323 abuts against the side of the C-shaped steel 6, keeping the two C-shaped steels 6 flush. Then, the bearing seat 25 is controlled to move towards the C-shaped steel 6, so that the guide roller 21 abuts against the side of the C-shaped steel 6. Next, the sliding plate 241 is driven, so that the limiting roller 22 abuts against the top surface of the C-shaped steel 6, thereby completing the limiting of the C-shaped steel 6. Finally, the adjusting rod 322 is rotated so that the nozzle of the welding gun 31 is aligned with the welding point of the C-shaped steel 6. The two welding guns 31 weld both sides of the C-shaped steel 6 at the same time. After the welding is completed, the clamping part 41 moves the C-shaped steel 6 to the next welding point to continue welding.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
