Description

Technical Field

[0001] This utility model relates to the technical field of H-beam resist welding equipment, specifically to corrugated web H-beam assembly welding equipment. Background Technology

[0002] In the field of steel structure manufacturing, corrugated web H-beams are widely used in bridge, construction, and machinery manufacturing industries due to their unique structural advantages, such as good shear resistance and high load-bearing capacity. However, there are currently many problems with the assembly and welding equipment for corrugated web H-beams.

[0003] In traditional corrugated web H-beam assembly and welding equipment, the flange assembly and welding mechanism usually uses a set mechanism to slide the flange to the vertical welding station. During the sliding process, the flange is prone to impact, which causes the flange to deform, thereby affecting the quality of the welded H-beam and increasing the product defect rate.

[0004] Furthermore, existing welding equipment has a low level of automation, requiring a significant amount of manual operation during the welding process. This not only results in low production efficiency but also increases labor costs and intensity. Additionally, existing equipment has poor adaptability to different specifications and thicknesses of sheet metal, making it difficult to meet diverse production needs.

[0005] Therefore, it is urgent to develop a plate welding equipment that is efficient, precise and highly automated. Utility Model Content

[0006] In view of the problems and shortcomings of the existing technology, this utility model provides a corrugated web H-beam assembly and welding equipment.

[0007] The technical solution of this utility model is as follows:

[0008] A corrugated web H-beam assembly and welding equipment, comprising:

[0009] The base consists of multiple crossbeams arranged parallel to each other along the direction of steel conveying, and a guide rail is provided on the top.

[0010] The web plate welding mechanism is fixedly installed in the middle of the base and includes a web plate frame and a chain conveyor. The web plate frame is connected to the base and the chain conveyor is provided at the top.

[0011] The wing plate welding mechanism includes a movable support, a tilting frame, a hydraulic tilting mechanism, a wing plate conveying system, and a positioning system;

[0012] The bottom of the mobile support is equipped with a drive wheel set, which forms a rolling pair with the guide rail. The tilting frame is connected to the mobile support through a connecting pin, the axis of which is parallel to the steel conveying direction. The hydraulic tilting mechanism is used to drive the tilting frame to tilt downward from the horizontal conveying station to the vertical welding station.

[0013] The wing plate conveying system includes multiple sets of conveying rollers arranged along the conveying direction and liftable electrode plates. The electrode plates are connected to the frame through a linear drive component. The positioning system includes a first roller group and a second positioning roller group. The first positioning roller is located inside the tilting frame, and the second positioning roller group is located outside the electrode plates. The second positioning roller group is equipped with an adjustment mechanism that can adjust the distance between the second positioning roller group and the first positioning roller group.

[0014] And robotic welding systems.

[0015] Preferably, the drive wheel assembly is a motor-driven wheel assembly, and the drive wheel assembly is equipped with an encoder.

[0016] The hydraulic tilting mechanism includes a double-acting hydraulic cylinder.

[0017] The linear drive is a hydraulic or electric linear drive.

[0018] The adjustment mechanism adopts a pneumatic linear drive component, which is equipped with a pressure adjustment device.

[0019] The base is provided with a limiting device to restrict the movement range of the movable support.

[0020] The chain conveyor includes a driving sprocket, a driven sprocket, and a closed-loop conveyor chain.

[0021] The web frame is connected to the middle of the base by bolts.

[0022] Preferably, the robotic welding system employs a six-axis welding robot equipped with a laser tracking system.

[0023] The beneficial effects of this utility model are:

[0024] First, the wing plate welding mechanism achieves rotation through linear drive components. Compared with the traditional sliding method, it is easier and more stable to operate. During the rotation process, it can accurately control the position of the wing plate, effectively avoid the impact and displacement of the wing plate during movement, improve the accuracy of the corrugated web and wing plate assembly, and thus ensure the welding quality.

[0025] Secondly, the combined use of the first and second positioning rollers can effectively fix the wing plate and prevent it from shaking during the welding process, thus further improving the welding quality.

[0026] Furthermore, the rational design of the conveyor rollers and electrode plates ensures that the wing plates are well supported and positioned during conveying and welding. The electrode plate spacing is adjustable to meet the welding requirements of wing plates of different thicknesses.

[0027] Furthermore, the installation of welding robots automates the welding process, significantly improving production efficiency. Welding robots can accurately perform welding according to preset programs, reducing errors caused by manual operation, ensuring consistent welding quality, and simultaneously lowering labor costs and intensity.

[0028] The equipment in this application has lower requirements for installation sites and has wider applicability. Attached Figure Description

[0034] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0035] Example

[0036] See Figures 1-3 A corrugated web H-beam assembly and welding equipment includes a base, a web assembly and welding mechanism, a wing plate assembly and welding mechanism, and a robotic welding system.

[0037] The base 1, serving as the fundamental support structure for the entire equipment, is composed of multiple crossbeams arranged in an array along the steel conveying direction. A guide rail is provided on the top, offering a stable track for the movement of the wing plate welding mechanism 3. The base 1 also features a limiting device to restrict the movement range of the movable support 31, preventing it from exceeding the predetermined range and ensuring the safety of equipment operation.

[0038] See Figure 1The web plate welding mechanism 2 is fixedly connected to the middle of the base 1, and includes a web plate frame 21 and a chain conveyor device. The bottom of the web plate frame 21 is bolted to the middle of the base 1, and the chain conveyor device on the upper part is used to transport the corrugated web plate to the set welding position. The chain conveyor device includes a driving sprocket, a driven sprocket, and a closed-loop conveyor chain. The chain drive mechanism has the characteristics of stable transmission and strong load-bearing capacity, which can ensure the stability of the corrugated web plate during the conveying process.

[0039] See Figure 2 and Figure 3 The wing plate welding mechanism 3 includes a movable support 31, a tilting frame 32, a hydraulic tilting mechanism, a wing plate conveying system, and a positioning system.

[0040] A drive wheel assembly is mounted at the bottom of the movable support 31, forming a rolling pair with the guide rail. The drive wheel assembly is motor-driven, and through a motor-driven transmission system, it enables the movable support 31 to move laterally along the base 1, allowing it to approach or move away from the web welding mechanism 2. Furthermore, an encoder is installed on the drive wheel assembly to detect the number of rotations, thereby precisely controlling the movement distance of the movable support 31 and ensuring a tight fit between the wing plate and the corrugated web.

[0041] The tilting frame 32 is connected to the movable support 31 via a connecting pin 33. The tilting frame 32 is attached to the upper part of the movable support 31 near the side of the web welding mechanism 2. The axis of the connecting pin 33 is parallel to the steel conveying direction. The hydraulic tilting mechanism is used to drive the tilting frame to tilt downwards from the horizontal conveying position to the vertical welding position. The hydraulic tilting mechanism includes a hydraulic or electric linear drive component, which can drive the tilting frame 32 to tilt downwards 90° from the horizontal position to the vertical position. This tilting method is simple and stable to operate and can accurately adjust the wing plate to the welding position.

[0042] The wing plate conveying system includes multiple sets of conveyor rollers 34 arranged along the conveying direction and liftable electrode plates 35. The conveyor rollers 34 are driven to rotate by a transmission system and have anti-slip textures on their surfaces to increase friction with the wing plates and prevent slippage during conveying. Electrode plates 35 are spaced apart between adjacent conveyor rollers 34 and connected to the frame via a linear drive, allowing for adjustable spacing between the electrode plates 35 and the tilting frame 32. When the wing plate is in the conveying position, the spacing between the electrode plates 35 and the tilting frame 32 is smaller than the spacing between the tilting frame 32 and the conveyor rollers 34, meaning the electrode plates are positioned below the conveyor rollers 34, facilitating the conveying of the wing plates. At the wing plate assembly welding position, the spacing is greater than the spacing between the tilting frame 32 and the conveyor rollers 34, separating the wing plates from the conveyor rollers 34 and allowing them to contact the electrode plates 35 to meet welding requirements. The surface of the electrode plates 35 is treated with an anti-stick coating to prevent adhesion during welding.

[0043] See Figure 3The positioning system includes a first roller group and a second positioning roller group 37. The first positioning roller is located inside the tilting frame 32, and the second positioning roller group 37 is located outside the electrode plate 35. The second positioning roller group 37 is equipped with an adjustment mechanism that can adjust the distance between the second positioning roller group 37 and the first positioning roller group 36. When the tilting frame 32 is in a vertical position, the first positioning roller is located below and the second positioning roller is located above. The second positioning roller can be adjusted along the width direction of the electrode plate 35 by a pneumatic linear drive to cooperate with the first positioning roller to fix the wing plate and prevent it from falling off. The pneumatic linear drive is equipped with a pressure adjustment device that can adjust the pressure according to the actual situation of the wing plate to ensure that the wing plate is firmly fixed.

[0044] See Figure 1 Preferably, the robotic welding system 4 employs a six-axis welding robot equipped with a laser tracking system and a welding torch attitude adjustment algorithm to precisely control the weld seam. The welding robot is positioned appropriately, such as above or to the side of the corrugated web and wing plate assembly welding station, to perform welding operations on the corrugated web and wing plates at the assembly welding station. The welding robot possesses high-precision welding capabilities and flexible motion trajectories, enabling it to accurately perform welding according to a preset program, ensuring consistent weld quality.

[0045] Working principle: First, the corrugated web plate is placed on the chain conveyor of the web plate welding mechanism 2 and transported to the designated position through the chain drive mechanism. At the same time, the wing plate is placed on the conveyor rollers 34 of the tilting frame 32 on both sides of the web plate welding mechanism 2. The conveyor rollers 34 are driven to rotate through the transmission system to transport the wing plate to the appropriate position.

[0046] Next, the second positioning roller is adjusted along the width direction of the electrode plate 35 by a pneumatic linear drive, cooperating with the first positioning roller to fix the wing plate. Then, the distance between the electrode plate 35 and the flipping frame 32 is adjusted by the pneumatic linear drive so that the electrode plate 35 contacts the wing plate. After that, the flipping frame 32 is flipped downwards by 90° to a vertical position by a hydraulic flipping mechanism.

[0047] Simultaneously, the moving support 31 is driven by the drive wheel set to move laterally along the base 1, bringing the wing plate closer to the corrugated web. Finally, the welding robot is started, and the corrugated web and wing plate are welded according to the preset program. After the welding is completed, the flipping frame 32 is flipped back to the horizontal state in the reverse order, the moving support 31 is moved away from the web welding mechanism 2, and the welded corrugated web H-beam is removed.

[0048] The above description represents a preferred embodiment of the present invention. However, the present invention is not limited to the above-described embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, all variations, equivalent substitutions, and improvements made without departing from the concept of the present invention should be included within the protection scope of the present invention.
