Description

Technical Field

[0001] This invention relates to the field of H-beam welding technology, and in particular to an automatic welding device and welding method for H-beam structural columns. Background Technology

[0002] H-beams are an economical and efficient structural steel profile with optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. They consist of one web and two flanges, and are named for their cross-section resembling the letter "H". Because all parts of an H-beam are arranged at right angles, it possesses advantages such as high bending resistance in all directions, simple construction, cost savings, and lightweight structure, and is now widely used. H-beams are commonly used as structural supports in various civil and industrial building structures. Since H-beams are manufactured to uniform specifications, but building structural supports often have varying length requirements, welding is necessary during construction to extend their length. Currently, most H-beam welding on construction sites is still done manually, with workers butt-welding two H-beams together. This welding method is inefficient and cannot guarantee consistent weld quality. Therefore, it is necessary to invent an automatic welding device and method for H-beam structural supports. Summary of the Invention

[0003] To address the above problems, this invention proposes an automatic welding device and welding method for H-shaped steel structure columns. The technical solution used is as follows:

[0004] An automatic welding device for H-beam steel structure columns includes a moving device, a support frame, a conveying device, a grinding device, a welding device, and a control end. Two support frames are symmetrically mounted on the moving device and are both driven to move by the moving device. Several sets of conveying devices are slidably mounted on each support frame along a straight line. These conveying devices support the H-beam and drive its movement. Grinding devices are installed on the ends of the two support frames that are close to each other, and these grinding devices are used to grind the welding surfaces of the H-beam.

[0011] Each conveying device includes a conveying frame, an electric cylinder, a lifting frame, and conveying rollers; the conveying frame is slidably mounted on a support frame; the lifting frame is slidably mounted on the conveying frame; the electric cylinder is fixedly mounted on the conveying frame, and its telescopic end is fixedly connected to the lifting frame; conveying rollers are rotatably mounted on both the conveying frame and the lifting frame, and H-beams are sandwiched between the two conveying rollers; clamping plates are installed on both sides of the conveying rollers, and the flange plates of the H-beams are sandwiched between the clamping plates and the conveying rollers.

[0012] Each of the grinding devices includes a support cylinder, a rotating frame, an XY-axis manipulator, a rotating assembly, and a grinding machine; the support cylinder is horizontally arranged and fixedly installed on the support frame, and the rotating frame is coaxially slidably installed on the side wall of the support cylinder; the rotating assembly is used to drive the rotating frame to slide around the axis of the support cylinder; the XY-axis manipulator is installed on the rotating frame, and the grinding machine is fixedly installed at the output end of the XY-axis manipulator.

[0013] The XY-axis manipulator includes a linear module one and a linear module two; the linear module one is fixedly mounted on the rotating frame along the axial direction of the support cylinder; the linear module two is fixedly mounted on the sliding end of the linear module one along the radial direction of the support cylinder; and the grinder is fixedly mounted on the sliding end of the linear module two.

[0015] An automatic welding method for H-beam steel structure columns, which uses the aforementioned automatic welding device for H-beam steel structure columns to weld two H-beams together, includes the following steps:

[0016] S1. Adjust the distance between the two support frames and the welding device using the moving device; adjust the distance between the conveyor frames on each support frame;

[0017] S2. Place the two H-beams that need to be welded together on the conveying devices of the two support frames respectively; start the electric cylinder one to drive the lifting frame to move, and the two conveying rollers of the same conveying device clamp the H-beams; the conveying rollers rotate, driving the H-beams to move.

[0018] After the welding surfaces of the S3 and H-beams are moved to the grinding device, the rotating assembly drives the rotating frame to rotate; the XY axis robot is started, and during the rotation of the rotating frame, the position of the grinding machine is adjusted, and the grinding machine is started to grind the welding surfaces of the H-beams;

[0019] S4. After grinding, the conveyor rollers continue to move the H-beams together, and the two H-beams are joined together; start the second electric cylinder, and the two clamping plates move closer to each other and clamp the joined H-beams together.

[0020] S5. Welder starts; the rotating component drives the rotating frame to rotate around the two H-beams being joined, and at the same time, the linear module three is started, which drives the welder to move. The welder welds the joint on one side of the two H-beams.

[0021] S6. The electric cylinder two drives the two clamping plates to move away from each other, starts the adjusting motor, and the clamping plates move, exposing all the butt joints of the two H-beams and no longer being blocked by the clamping plates; the rotating component drives the rotating frame to rotate around the two H-beams that are joined together, and at the same time starts the linear module three, drives the welder to move, and the welder welds all the butt joints of the two H-beams.

[0022] S7. After welding is completed, the conveyor rollers will transport the welded H-beams out.

[0024] 1.

The rotating frame and linear module three drive the welding device to move. When the welding of one side of the joint of the two H-beams is completed, the clamping mechanism releases the H-beams, and the welding device moves under the drive and welds all the joints, ensuring that all joints are welded.

[0025] 2. The present invention, through the coordinated design of the moving device, the support frame and the conveying device, can adjust the distance between the two support frames and the distance between the conveying devices on the support frames, so that the conveying devices can support and convey H-beams of different lengths.

Therefore, they should not be construed as limiting this invention. Example:

[0051] This embodiment is used to weld two H-shaped steel structure columns together.

[0052] like Figure 1 As shown, an automatic welding device for H-beam steel structure columns includes a moving device 1, a support frame 2, a conveying device 3, a grinding device 4, and a welding device 5. Two support frames 2 are provided, symmetrically mounted on the moving device 1 in a straight line, and both are driven to move by the moving device 1. Three sets of conveying devices 3 are slidably mounted on each support frame 2 in a straight line. The conveying devices 3 are used to support the H-beam and drive the H-beam to move. A grinding device 4 is installed on one end of each support frame 2 that is close to each other. The grinding device 4 is used to grind the welding surface of the H-beam. A welding device 5 is provided between the two support frames 2, and the welding device 5 is driven to move by the moving device 1 for welding the two H-beam steel structure columns.

[0053] like Figure 2 As shown, the moving device 1 includes a support slide rail 101, a sliding plate 102, a moving rack 103, a moving gear 104, and a moving motor 105; five sliding plates 102 are slidably mounted on the support slide rail 101, a support frame 2 is mounted on two sliding plates 102, and a welding device 5 is mounted on one sliding plate 102; the moving rack 103 is horizontally fixedly mounted on the support slide rail 101; a moving motor 105 is fixedly mounted on each sliding plate 102; a moving gear 104 is coaxially fixedly mounted on the output end of each moving motor 105, and the moving gear 104 meshes with the moving rack 103;

[0054] Specifically, the moving motor 104 is started, the moving gear 104 rotates, and the sliding plate 102 slides along the moving rack 103 on the support slide rail 101.

[0055] like Figure 5As shown, each conveying device 3 includes a conveying frame 301, an electric cylinder 302, a lifting frame 303, and conveying rollers 304. The conveying frame 301 is slidably mounted on the support frame 2 via a linear slide rail. A fixing mechanism (not shown) is provided between the conveying frame 301 and the support frame 2 to fix the conveying frame 301. The lifting frame 303 is vertically slidably mounted on the conveying frame 301. The electric cylinder 302 is fixedly mounted on the top of the conveying frame 301, and its telescopic end is fixedly connected to the lifting frame 303. Conveying rollers 304 are rotatably mounted on the conveying frame 301 below the lifting frame 303 and on the lifting frame 303. H-beams are sandwiched between two conveying rollers 304. Circular clamping plates 3041 are installed on both sides of the conveying rollers 304, and the flanges of the H-beams are sandwiched between the clamping plates 3041 and the conveying rollers 304.

[0056] Specifically, the electric cylinder 302 drives the lifting frame 303 to move upward, and the worker places the H-beam on the conveying roller 304 located on the conveying frame 301. The lower half of the flange of the H-beam is placed between the conveying roller 304 and the clamping plate 3041 located on the conveying frame 301. The electric cylinder 302 drives the lifting frame 303 to move downward, and the conveying roller 304 on the lifting frame 303 presses on the H-beam, and the upper half of the flange of the H-beam extends between the conveying roller 304 and the clamping plate 3041, thus supporting the H-beam. After the conveying roller 304 is started, the rotation of the conveying roller 304 can drive the H-beam to move.

[0057] like Figure 6-7 As shown, each grinding device 4 includes a support cylinder 401, a rotating frame 402, an XY axis robot 403, a rotating assembly 404, and a grinding machine 405; the support cylinder 401 is horizontally arranged and fixedly installed on the support frame 2, and the rotating frame 402 is coaxially slidably installed on the side wall of the support cylinder 401.

[0058] The XY-axis robot 403 includes a linear module 1 4031 and a linear module 2 4032; the linear module 1 4031 is fixedly mounted on the rotating frame 402 along the axial direction of the support cylinder 401; the linear module 2 4032 is fixedly mounted on the sliding end of the linear module 1 4031 along the radial direction of the support cylinder 401; and the grinder 405 is fixedly mounted on the sliding end of the linear module 2 4032.

[0059] The rotating assembly 404 includes a rotating motor 4041, a bevel gear 4042, and a rotating gear 4043; the rotating motor 4041 is fixedly mounted on the rotating frame 402, and the bevel gear 4042 is coaxially fixedly mounted on its output end; the rotating gear 4043 is coaxially fixedly mounted on the support cylinder 401; the bevel gear 4042 and the rotating gear 4043 mesh with each other.

[0060] Specifically, starting the rotating motor 4041 causes the bevel gear 4042 to rotate, which in turn drives the rotating gear 4043 to rotate. This causes the rotating frame 402 to slide along the rotating gear 4043 and around the axis of the support cylinder 401. The XY axis manipulator 403 and the grinder 405 move accordingly. Linear module one 4031 drives linear module two 4032 to move axially along the support cylinder 401. Linear module two 4032 drives the grinder 405 to move radially along the support cylinder 401. During the sliding process of the rotating frame 402 around the axis of the support cylinder 401, the position of the grinder 405 can be adjusted by adjusting linear module one 4031 and linear module two 4032, so that the grinder 405 can grind the welded surface of the H-beam steel.

[0061] like Figure 8-11 As shown, the welding device 5 includes a welding frame 501, a clamping mechanism 502, a rotating frame 503, a linear module 504, a rotating assembly 505, a welder 506, and a steering motor 507. The welding frame 501 is fixedly mounted on the sliding plate 102, and has an opening in the middle. The rotating frame 503 is rotatably mounted on the periphery of the opening of the welding frame 501 and is driven by the rotating assembly 505 to rotate around the two H-beams being joined. The rotating frame 503 is an incomplete annular shape. The linear module 504 is radially fixedly mounted on the rotating frame 503 along the rotation trajectory of the rotating frame 503. A connecting block is rotatably mounted on the sliding end of the linear module 504, and a locking mechanism (not shown) is provided between the connecting block and the sliding end of the linear module 504 to fix the connecting block. The welder 506 is rotatably mounted on the connecting block. The steering motor 507 is fixedly mounted on the connecting block, and its output end is fixedly connected to the welder 506.

[0062] The clamping mechanism 502 includes a clamping plate 5021, an electric cylinder 5022, a mounting frame 5023, an adjusting motor 5024, an adjusting gear 5025, and an adjusting rack 5026. The clamping plates 5021 are located within the opening of the welding frame 501, and a pair is provided, symmetrically arranged on the left and right sides of the H-beams awaiting welding. The clamping plates 5021 are C-shaped plates, and the two clamping plates 5021 work together to clamp the two H-beams being joined. An adjusting rack 5026 is fixedly installed on each clamping plate 5021. Each adjusting rack 5026 has two mounting brackets 5023 slidably mounted on it, and each mounting bracket 5023 has an adjusting gear 5025 rotatably mounted on it, meshing with the corresponding adjusting rack 5026; each adjusting gear 5025 is coaxially and fixedly connected to the output end of the adjusting motor 5024 fixedly mounted on the corresponding mounting bracket 5023; each mounting bracket 5023 is fixedly connected to the telescopic end of an electric cylinder 5022, and the electric cylinder 5022 is fixedly mounted on the welding bracket 501 through a connecting plate;

[0063] The rotating assembly 505 includes a rotary motor 5051 and drive wheels 5052; the rotating frame 503 has a limiting groove around its outer end, and two drive wheels 5052 and four connecting wheels are rotatably mounted on the welding frame 501 in the circular groove; the rotary motor 5051 is fixedly mounted on the welding frame 501, and its output end is coaxially fixedly connected to the input gear; the input gear meshes with the output gear, and both the input gear and the output gear are rotatably mounted on the welding frame 501; the output gear is connected to the two drive wheels 5052 through a transmission wheel and a transmission belt.

[0064] Specifically, the electric cylinder 5022 drives the two clamping plates 5021 to move closer or further apart; after the adjusting motor 5024 starts, the adjusting gear 5025 rotates, and the adjusting rack 5026 moves back and forth relative to the adjusting gear 5025, causing the clamping plates 5021 to move back and forth accordingly; after the rotary motor 5051 starts, it drives the two drive wheels 5052 to rotate through the input gear, output gear, transmission wheel, and transmission belt, and the drive wheels 5052 drive the rotating frame 503 to rotate, while the connecting wheel also rotates, enabling the rotating frame 503 to rotate continuously; the linear module 504 rotates with the rotating frame 503, and the linear module 504 drives the welder 506 to move radially along the rotation trajectory of the rotating frame 503; the connecting block can adjust the angle of the welder 506 in the vertical plane, and the steering motor 507 can drive the welder 506 to rotate in a plane perpendicular to the vertical plane, thereby realizing multi-angle welding of the welder 506 during the movement of the rotating frame 503 and the linear module 504.

[0065] This embodiment also includes a control terminal 6, such as Figure 12 As shown, the control terminal 6 includes a main controller, a human-machine interface display screen, an information transmission module, a storage module, and a power supply module. The main controller is electrically connected to the human-machine interface display screen, the information transmission module, the storage module, the power supply module, as well as the moving motor 105, electric cylinder 302, conveying roller 304, linear module 1 4031, linear module 2 4032, rotary motor 4041, grinder 405, electric cylinder 2 5022, adjusting motor 5024, linear module 3 504, rotary motor 5051, welder 506, and steering motor 507. The system includes: a main controller for controlling the operation of the automatic welding device for the entire H-shaped steel structure column; a human-machine interface display screen for setting the operating values ​​of the moving device 1, conveying device 3, grinding device 4, and welding device 5, as well as automatic operation control after the set values ​​are determined; an information transmission module for information transmission between the main controller and the moving device 1, conveying device 3, grinding device 4, and welding device 5; a power supply module for providing a stable power supply to the control terminal 6; and a storage module for storing the operating information data of the automatic welding device for the entire H-shaped steel structure column.

[0066] The automatic welding device for H-beam steel structure columns is used as follows:

[0067] Step 1: Start the moving motor 105 to move the sliding plate 102 and adjust the position of the support frame 2 and the welding device 5; adjust the position of the conveyor frame 301 on the support frame 2, and after adjustment, fix the conveyor frame 301 through the fixing mechanism; rotate the connecting block to adjust the angle of the welder 506 in the vertical plane, and after adjustment, fix the connecting block through the locking mechanism.

[0068] The second step involves the electric cylinder 302 driving the lifting frame 303 to rise, and the worker placing the H-beam between the conveying rollers 304. The electric cylinder 302 then drives the lifting frame 303 to descend, and the two conveying rollers 304 clamp the H-beam. The conveying rollers 304 are then activated, causing the two H-beams to move closer together.

[0069] Third step: After the welded surface of the H-beam passes through the support cylinder 401, start the rotating motor 4041 and rotate the rotating frame 402; at the same time, start the XY axis robot 403 and the grinding machine 405. During the rotation of the rotating frame 402, the XY axis robot 403 adjusts the position of the grinding machine 405 and the grinding machine 405 grinds the welded surface of the H-beam.

[0070] Step 4: After grinding, the conveyor roller 304 continues to move the H-beams, and the two H-beams are joined together; start the electric cylinder 5022, and the two clamping plates 5021 move closer to each other and clamp the joined H-beams.

[0071] Step 5: Welder 506 is started; the rotary motor 5051 is started, and the rotating frame 503 drives the linear module 3 504 to rotate around the two H-beams being joined; at the same time, the linear module 3 504 and the steering motor 507 are started. The linear module 3 504 drives the welder 506 to move, and the steering motor 507 drives the welder 506 to rotate. The welder 506 welds the joint on one side of the two H-beams.

[0072] Step 6: Electric cylinder 2 5022 drives the two clamping plates 5021 to move away from each other, and the adjusting motor 5024 is started. The clamping plates 5021 move, and all the butt joints of the two H-beams are exposed and no longer blocked by the clamping plates 5021. The rotating frame 503 continues to rotate around the two H-beams. At the same time, the linear module 3 504 and the steering motor 507 are started. The welder 506 moves and adjusts its angle. The welder 506 welds all the butt joints of the two H-beams.

[0073] Step 7: After welding is completed, the 304 conveyor rollers will transport the welded H-beams out.

[0074] The above steps complete the automatic welding of the H-shaped steel structure column.
