Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a double-arc double-wire welding guide frame. Background Technology

[0002] Dual-arc dual-wire welding uses two welding guns (dual wires) to generate two electric arcs (dual arcs) that work together on the same molten pool for welding. The two welding wires are driven by independent power supplies and wire feeders, but their parameters can be set collaboratively.

[0003] A search revealed that Chinese patent CN202222463944.5 discloses a double-arc, double-wire high-efficiency welding mechanism for H-beams. This mechanism utilizes an auxiliary mechanism installed on the inner top of a support frame. Operators place a flat steel plate on top of the conveying mechanism, then place a vertical steel plate at the center of the top of the flat steel plate, facilitating direct positioning of the vertical steel plate. High-efficiency mechanisms are equidistantly installed on the outer side of the conveying mechanism. Operators place limiting plates on the outer side of the conveying rollers, move the positions of the two sets of limiting plates, and then fix the limiting plates to the outer side of the conveying rollers using bolts. These limiting plates effectively restrict the flat steel plate's position, preventing it from tilting when placed on top of the conveying rollers, which would affect the welding effect between the flat and vertical steel plates and thus the quality of the finished product.

[0004] The aforementioned technical solution has the following drawbacks: while the double-arc, double-wire welding guide frame structure can position a single H-beam using positioning components, facilitating welding of the steel plate by the welding torch during movement, it can only weld one H-beam in actual use. To further improve processing efficiency, a double-arc, double-wire welding guide frame is proposed, employing a symmetrical double-sided H-beam positioning frame design, allowing workpieces to be clamped simultaneously on both sides of the equipment. The mobile guide frame body can simultaneously complete the welding of two workpieces using its welding system during a single movement, effectively increasing output per unit time, solving the bottleneck of mass production efficiency, providing a complete high-precision solution, and ensuring the stability and consistency of welding quality.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background technology of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides a double-arc, double-wire welding guide frame, which solves the problems of low processing efficiency, insufficient equipment versatility, limited precision level, and poor adaptability to complex working conditions caused by the inability of traditional welding guide frames to weld multiple workpieces at the same time.

[0008] The solution of this utility model to solve the above-mentioned technical problems is as follows: a double-arc, double-wire welding guide frame, including a movable guide frame body, a first welding torch adjustment module, a second welding torch adjustment module, a welding torch body, a double-wire welding power supply, a wire feeder, a control cabinet, an H-beam positioning frame, an H-beam pad, and a limiting guide rail. The H-beam positioning frame and the limiting guide rail are detachably laid and installed on the ground. The movable guide frame body moves along the limiting guide rail. The first welding torch adjustment module is set on the movable guide frame body. The second welding torch adjustment module is detachably installed on the first welding torch adjustment module. The welding torch body is set on the drive end of the second welding torch adjustment module. The double-wire welding power supply is set in the control cabinet. The wire feeder is set on the movable guide frame body. The H-beam pad is detachably installed on the H-beam positioning frame.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the main body of the mobile arc guide frame includes an AGV transport vehicle, a load-bearing bracket, and a load-bearing beam. Two AGV transport vehicles and two load-bearing brackets are provided, connected one-to-one. The load-bearing beam is mounted on the load-bearing bracket, and a mounting slot is provided on the load-bearing beam corresponding to the first welding torch adjustment module. The first welding torch adjustment module is mounted in the mounting slot. The AGV transport vehicle is responsible for the automatic and precise movement of the arc guide frame along the preset limit guide rail. The load-bearing bracket and the load-bearing beam constitute a robust frame, used to support the weight of the welding torch adjustment module, wire feeder, and all other upper devices, and to resist various forces and vibrations during the welding process. The mounting slot provides integrated installation space for the first welding torch adjustment module.

[0011] Furthermore, the first welding torch adjustment module includes a brake stepper motor, a ball screw, a screw nut, a load-bearing slider, a load-bearing rod, and a mounting base. The brake stepper motor and the load-bearing rod are both housed in a mounting slot. The ball screw is located at the drive end of the brake stepper motor and is connected to the screw nut. The load-bearing slider is mounted on both sides of the screw nut and slides linearly along the outer wall of the load-bearing rod. The mounting base is installed at the load-bearing slider and the screw nut. This allows the welding torch to be precisely adjusted linearly in one direction, enabling accurate positioning of the welding torch to a preset welding position. The motor's brake function immediately locks the position upon power failure, preventing the welding torch from sliding down due to its own weight, ensuring safety and reliability. The ball screw pair has a high load capacity, and the cooperation between the load-bearing slider and the load-bearing rod effectively prevents rotation and shaking during movement, ensuring smooth operation and no crawling even under load of the welding torch and robotic arm.

[0012] Furthermore, one end of the ball screw is rotatably connected to the mounting groove, and both ends of the load-bearing rod are fixedly installed on the inner wall of the mounting groove. The load-bearing slider has a sliding hole corresponding to the load-bearing rod. The method of rotatably connecting one end of the screw and fixing both ends of the load-bearing rod enhances the rigidity of the entire transmission system, reduces vibration and deformation, and helps maintain long-term accuracy.

[0013] Furthermore, the mounting groove has a strip-shaped hole corresponding to the load-bearing slider and the lead screw nut. The strip-shaped hole is equipped with a retractable dust cover. The mounting base is connected to the No. 2 welding torch adjustment module by bolts. The retractable dust cover can effectively prevent common welding site contaminants such as spatter and dust from entering the precision ball screw and guide rail, greatly extending the service life of the equipment and reducing maintenance needs. The bolt connection method allows the six-axis robotic arm of the No. 2 welding torch adjustment module to be easily installed, disassembled or replaced, improving the modularity of the equipment and its adaptability to different processes.

[0014] Furthermore, the second welding torch adjustment module employs a six-axis welding robotic arm. The welding torch body is bolted to the normal plate of the sixth axis of the six-axis welding robotic arm. The six-axis robotic arm is responsible for the fine-tuning of the final welding torch posture and the movement of complex trajectories. It provides six degrees of freedom of movement, enabling the welding torch tip to be flexibly delivered to and maintained at any desired position and angle in three-dimensional space. The six-axis design allows it to mimic the flexibility of a human arm, easily allowing the welding torch to approach the weld position at the optimal angle. It is particularly suitable for welding fillet welds, complex shapes, or workpieces with slight deformation. It can precisely control key process parameters such as the welding torch angle relative to the weld, working angle, travel angle, and wire extension, ensuring excellent weld formation. By cooperating with the control system, complex welding paths can be programmed to adapt to various welding tasks, resulting in a high degree of automation.

[0015] Furthermore, two H-beam positioning frames are provided, symmetrically arranged on both sides of the main body of the movable guide arc frame. The H-beam positioning frames are evenly provided with bolt holes. The shape of the H-beam pad is selected according to the H-beam model and is installed on the H-beam positioning frame with bolts. By changing the pad with different shapes and utilizing the evenly distributed bolt holes, the positioning system can be quickly adjusted to adapt to various models and sizes of H-beams, resulting in high equipment utilization. The two H-beam positioning frames on both sides can each hold two H-beams to be welded, allowing two sets of welding parts to be welded simultaneously while one guide arc frame is moving, thereby effectively improving work efficiency.

[0016] Furthermore, the top of the H-beam positioning frame is provided with a right-angled mounting slot for quick initial positioning of the H-beam flanges. The robust positioning frame ensures that the H-beam workpiece is firmly clamped throughout the welding process and will not move due to thermal deformation or external force. This is a prerequisite for ensuring welding accuracy and consistency.

[0017] This utility model provides a double-arc, double-wire welding guide frame, which has the following advantages:

[0018] 1. It solves the production efficiency bottleneck problem of traditional arc guide frames, completely changes the mode of traditional equipment that can only weld one workpiece at a time, and realizes simultaneous welding on both sides, which can theoretically double the production efficiency. It adopts a symmetrical double-sided H-shaped steel positioning frame design, which allows workpieces to be clamped on both sides of the equipment at the same time. The mobile arc guide frame can simultaneously complete the welding of two workpieces using its welding system during one movement, which effectively improves the output per unit time and solves the mass production efficiency bottleneck.

[0019] 2. This design solves the problem of insufficient versatility of traditional arc guide frame equipment. Through an adjustable and replaceable positioning and support system, it addresses the issue that existing equipment may have difficulty quickly adapting to welding different models and sizes of H-beams, achieving multi-purpose functionality and significantly improving equipment utilization and application range. The AGV transport vehicle, load-bearing bracket, and load-bearing beam form a robust mobile foundation, effectively resisting welding vibration and ensuring stable equipment operation. The No. 1 welding torch adjustment module uses a brake stepper motor and ball screw pair drive, with the load-bearing slider and load-bearing rod working together to achieve micron-level precise, stable, and slip-free linear positioning of the welding torch in important directions, laying the foundation for welding consistency. The No. 2 welding torch adjustment module uses a six-axis welding robotic arm, giving the welding torch six degrees of freedom of movement, which can precisely control the working angle, travel angle, and spatial position of the welding torch, ensuring optimal forming quality for various welds (especially fillet welds).

[0020] 3. It solves the problem of limited precision of traditional guide arc frames. It provides a complete high-precision solution to the problems that traditional equipment may have, such as inaccurate movement and positioning and insufficient freedom of welding torch adjustment. It ensures the stability and consistency of welding quality. The evenly distributed bolt holes and replaceable H-beam pads on the H-beam positioning frame allow the equipment to be quickly adapted to various specifications of H-beams through simple adjustments. The equipment has a high utilization rate and reduces the investment in special tooling. The powerful flexibility of the six-axis robotic arm enables it to handle workpieces with slight assembly errors or deformation, ensuring welding quality under non-ideal conditions.

[0021] 4. It solves the problem of poor adaptability to complex working conditions. Through the design of a high degree of freedom robotic arm, it solves the problem of adaptability to working conditions where the workpiece has slight deformation or requires complex welding gun posture to complete high-quality welding. Using AGV transport vehicles as the mobile base, it realizes the automated movement of the welding process. It can be integrated with the control system to realize the automation of the entire welding process, reducing the dependence on skilled operators. All motor movements can be programmed and controlled by the control cabinet, making it easy to realize the repetition and mass production of complex welding paths.

[0034] Preferably, the main body 1 of the mobile arc guide frame includes an AGV transport vehicle 101, a load-bearing bracket 102, and a load-bearing beam 103. Two AGV transport vehicles 101 and two load-bearing brackets 102 are each provided and connected in a one-to-one correspondence. The load-bearing beam 103 is located on the load-bearing bracket 102, and a mounting slot 104 is provided on the load-bearing beam 103 corresponding to the first welding torch adjustment module 2. The first welding torch adjustment module 2 is located within the mounting slot 104. The AGV transport vehicle is responsible for enabling the automatic and precise movement of the arc guide frame along the preset limit guide rail. The load-bearing bracket and the load-bearing beam constitute a robust frame, used to support the weight of the welding torch adjustment module, wire feeder, and all other upper devices, and to resist various forces and vibrations during the welding process. The mounting slot provides integrated installation space for the first welding torch adjustment module.

[0035] Preferably, the first welding torch adjustment module 2 includes a brake stepper motor 201, a ball screw 202, a screw nut 203, a load-bearing slider 204, a load-bearing rod 205, and a mounting base 206. The brake stepper motor 201 and the load-bearing rod 205 are both housed in the mounting groove 104. The ball screw 202 is located at the drive end of the brake stepper motor 201 and is connected to the screw nut 203. The load-bearing slider 204 is mounted on both sides of the screw nut 203 and slides linearly along the outer wall of the load-bearing rod 205. The mounting base 206 is installed on the load-bearing slider 204 and the lead screw nut 203, which can drive the welding torch to make precise linear displacement adjustment in one direction. The adjustable welding torch can be accurately positioned to the preset welding position. The motor's brake function can lock the position immediately when the power is off, preventing the welding torch from sliding down due to its own weight, which is safe and reliable. The ball screw pair has a high load capacity. The cooperation between the load-bearing slider and the load-bearing rod effectively prevents rotation and shaking during the movement, ensuring that even when the welding torch and the robotic arm are under load, it can run smoothly without crawling.

[0036] Preferably, one end of the ball screw 202 is rotatably connected to the mounting groove 104, and both ends of the load-bearing rod 205 are fixedly installed on the inner wall of the mounting groove 104. The load-bearing slider 204 has a sliding hole corresponding to the load-bearing rod 205. The method of rotatably connecting one end of the screw and fixing both ends of the load-bearing rod enhances the rigidity of the entire transmission system, reduces vibration and deformation, and helps maintain long-term accuracy.

[0037] Preferably, the mounting groove 104 has a strip-shaped hole corresponding to the load-bearing slider 204 and the lead screw nut 203. The strip-shaped hole is equipped with a retractable dust cover. The mounting base 206 is connected to the No. 2 welding torch adjustment module 3 by bolts.

The bolt connection method allows the six-axis robotic arm of the No. 2 welding torch adjustment module to be easily installed, disassembled or replaced, which improves the modularity of the equipment and its adaptability to different processes.

[0038] Preferably, the second welding torch adjustment module 3 adopts a six-axis welding robotic arm. The welding torch body 4 is bolted to the normal plate of the sixth axis of the six-axis welding robotic arm. The six-axis robotic arm is responsible for the fine adjustment of the final welding torch posture and the movement of complex trajectories. It provides six degrees of freedom of movement, which can flexibly deliver and hold the welding torch tip to any desired position and angle in three-dimensional space. The six-axis design allows it to mimic the flexibility of the human arm, easily allowing the welding torch to approach the weld position at the optimal angle. It is especially suitable for fillet welds, welding of workpieces with complex shapes or slight deformations. It can precisely control key process parameters such as the angle of the welding torch relative to the weld (working angle, travel angle) and the wire extension, ensuring the formation of excellent weld formation. By cooperating with the control system, complex welding paths can be programmed to adapt to various welding tasks, with a high degree of automation.

By changing the pads of different shapes and using the evenly distributed bolt holes, the positioning system can be quickly adjusted to adapt to various models and sizes of H-beams, resulting in high equipment utilization. The two H-beam positioning frames 8 on both sides can each hold two H-beams to be welded, so that two sets of welding parts can be welded simultaneously when one guide arc frame moves, thereby effectively improving work efficiency.

[0040] Preferably, the top of the H-beam positioning frame 8 is provided with a right-angled mounting slot for quick preliminary positioning of the H-beam flange. The robust positioning frame ensures that the H-beam workpiece is firmly clamped throughout the welding process and will not move due to thermal deformation or external force.

Screw the screw nut 203 with the load-bearing slider 204 into the ball screw 202. At the same time, put the load-bearing slider 204 on the load-bearing rod 205. Finally, install the mounting base 206 on the screw nut 203 and the load-bearing slider 204 to ensure a firm connection. Install the retractable dust cover for the strip hole.

[0049] Install the No. 2 welding torch adjustment module 3 and the welding torch: Fasten the six-axis welding robot arm (i.e., the No. 2 welding torch adjustment module 3) to the mounting base 206 of the No. 1 welding torch adjustment module 2 through the mounting holes on its base with high-strength bolts, and install the welding torch body 4 to the flange of the sixth axis of the six-axis robot arm with bolts.

[0056] Phase 4: Welding Execution

[0057] Initial positioning: The mobile guide arc frame body 1 is moved to the welding start position by the AGV transport vehicle 101;

[0058] Precise positioning of the welding torch: First, by controlling the brake stepper motor 201 of the first welding torch adjustment module 2, the ball screw 202 is driven to rotate, so that the entire welding torch mechanism moves along the direction of the mounting groove 104 for coarse adjustment and large-range positioning. Then, the six-axis welding robot arm 3 is used for fine adjustment, flexibly changing the spatial posture and precise position of the welding torch body 4, so that it is aligned with the weld start point and forms the optimal working angle and travel angle. Welding starts: The welding program is started in the control system, and the AGV begins to move forward at a constant speed along the guide rail. At the same time, the dual-wire welding power supply 5 and the wire feeder 6 start to work, generating a dual arc for welding. Synchronous welding and monitoring: During the movement of the AGV, the welding systems on both sides work synchronously to complete the welding of two H-beam steel workpieces on both sides at one time.
