Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of welding equipment technology, and more specifically, to a high-frequency welding equipment for H-shaped steel structures. Background Technology

[0002] H-beams are an important structural material widely used in construction, bridges, machinery, metallurgy and other industries. They have high load-bearing capacity and good bending resistance. Welding is a crucial part of the manufacturing process of H-beams. Through welding technology, different parts of H-beams are connected to form the required steel structure components.

[0003] According to a public announcement of an H-beam steel structure welding device (publication number: CN222660603U), it includes a support platform and an H-beam body. A support plate is fixed to the upper end of the support platform, and two long plates symmetrical about the center of the support platform are set on the upper end of the support plate. Clamping components for clamping the H-beam body are set on the upper end of the long plates. However, in the above device, it is difficult to achieve the effect of positioning rod fixing the steel plate during the welding process and tilting the positioning rod downward to unload the steel plate after welding. It is difficult to ensure that the position and angle of the steel plate remain unchanged during welding, thereby reducing the welding accuracy and making it difficult to avoid welding defects caused by steel plate displacement. At the same time, it is difficult to ensure the smooth unloading process, which needs to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a high-frequency welding equipment for H-shaped steel structures, which solves the technical problems in related technologies / prior technologies that make it difficult to achieve the effect of fixing the steel plate with a positioning rod during the welding process, tilting the positioning rod downward to unload the steel plate after welding, making it difficult to ensure that the position and angle of the steel plate remain unchanged during welding, thereby reducing the welding accuracy, making it difficult to avoid welding defects caused by steel plate offset, and making it difficult to ensure the smooth unloading process.

[0005] According to one aspect, at least one embodiment of this disclosure provides a high-frequency welding equipment for H-shaped steel structures, including a protective plate, a support leg fixedly connected to the bottom of the protective plate, and a steel plate disposed on the top of the protective plate;

[0006] The top of the protective plate is equipped with a fixing device, which includes an electric telescopic rod fixedly connected to the bottom of the protective plate. A fixing plate is fixedly connected to the telescopic end of the electric telescopic rod. A positioning plate is fixedly connected to the side of the fixing plate. A support plate is fixedly connected to the bottom of the protective plate. A rotating rod passes through the side of the support plate. A fixing block is rotatably connected to the circumferential surface of the rotating rod. A sliding groove is formed on the side of the fixing block. A fixing rod is fixedly connected to the side of the positioning plate. A connecting rod is fixedly connected to the bottom of the fixing block. A positioning rod is fixedly connected to the side of the connecting rod. A support rod is fixedly connected to the side of the protective plate. A mounting plate is fixedly connected to the bottom of the protective plate.

[0007] The system also includes two support rods that are symmetrical about each other along the vertical central axis of the protective plate. The design of the support rods can fix the steel plate and prevent the position of the steel plate from shifting during the welding process.

[0008] For example, in a high-frequency welding device for H-shaped steel structures provided in at least one embodiment of this disclosure, the circumferential surface of the fixing rod is in contact with the inner wall of the slide groove, and the number of the positioning plates is set to two, which are symmetrical about each other along the vertical central axis of the fixing plate. The design of the fixing rod and the slide groove can ensure that the position and angle of the steel plate remain unchanged during welding, thereby improving the welding accuracy and avoiding welding defects caused by steel plate offset.

[0009] According to another aspect, at least one embodiment of this disclosure also provides a high-frequency welding equipment for H-shaped steel structures, including a fixing device comprising a feeding structure, the feeding structure comprising a support block, the support block being fixedly connected to the bottom of a protective plate, a hydraulic cylinder being fixedly connected to the bottom of the support block, one end of the hydraulic cylinder being slidably connected to a force-bearing rod via a piston, the other end of the hydraulic cylinder being slidably connected to a hydraulic rod via a piston, and a push plate being fixedly connected to the side of the hydraulic rod.

[0010] For example, in at least one embodiment of the high-frequency welding equipment for H-shaped steel structures provided by this disclosure, the force-bearing rod is located on the movement trajectory of the fixed plate, and the hydraulic cylinder is now configured as an L-shape. The precise control of the hydraulic system ensures the smooth and accurate feeding of the steel plate, avoiding the problems of steel plate position deviation or uneven feeding caused by manual intervention or equipment inaccuracy, thereby improving the accuracy in the production process.

[0011] A spring is fixedly connected to the side of the hydraulic cylinder. The end of the spring away from the hydraulic cylinder is fixedly connected to the circumferential surface of the force-bearing rod. The design of the spring allows the force-bearing rod to automatically reset, reducing manual intervention.

[0012] The spring is initially in a relaxed state, and the steel plate is located on the movement trajectory of the push plate. The push plate is designed to achieve automatic feeding, reducing manual intervention.

[0013] The protective plate is equipped with a robotic arm on its top and a welding structure on its side. This design enables automatic welding and improves the efficiency of the entire production line.

[0014] The number of mounting plates is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate. The design of the mounting plates can fix the steel plate from multiple directions, ensuring the stability and accuracy of the steel plate.

[0015] The number of positioning rods is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate. The design of the positioning rods can accurately fix the position of the steel plate and prevent position displacement during the welding process.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] In this disclosure, the force that drives the fixed plate to move via an electric telescopic rod cooperates with components such as the positioning plate, support plate, and fixing block in the fixing device. This achieves the effect of the fixed block rotating along the rotating rod by the displacement of the fixed rod, which in turn drives the connecting rod to rotate, and then the positioning rod to rotate. This achieves the effect of the positioning rod fixing the steel plate during welding, and the positioning rod tilting downwards to unload the steel plate after welding. This ensures that the position and angle of the steel plate remain unchanged during welding, thereby improving welding accuracy and avoiding welding defects caused by steel plate misalignment. At the same time, it ensures smooth unloading and avoids operational difficulties caused by improper fixing methods.

[0018] In this disclosure, the force exerted by the fixed plate pressing the force-bearing rod cooperates with the hydraulic cylinder, hydraulic rod, and push plate components in the fixing device. This enables the liquid inside the hydraulic cylinder to push another piston to move, the piston to push the hydraulic rod to move, and then the hydraulic rod to push the push plate to move. The push plate then pushes the steel plate through the positioning rod to complete the unloading function, achieving the effect of automatic unloading. This ensures the smooth and accurate unloading of the steel plate and avoids problems such as steel plate position deviation or uneven unloading caused by manual intervention or equipment inaccuracy, thereby improving the precision of the production process.

Detailed Implementation

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, it illustrates a high-frequency welding equipment for H-shaped steel structures in one embodiment of the present disclosure, including a protective plate 101, a support leg 102 fixedly connected to the bottom of the protective plate 101, and a steel plate 104 provided on the top of the protective plate 101.

[0033] A fixing device 2 is provided on the top of the protective plate 101. The fixing device 2 includes an electric telescopic rod 201, which is fixedly connected to the bottom of the protective plate 101. A fixing plate 202 is fixedly connected to the telescopic end of the electric telescopic rod 201. A positioning plate 203 is fixedly connected to the side of the fixing plate 202. A support plate 204 is fixedly connected to the bottom of the protective plate 101. A rotating rod 208 passes through the side of the support plate 204. A fixing block 205 is rotatably connected to the circumferential surface of the rotating rod 208. A sliding groove 206 is provided on the side of the fixing block 205. A fixing rod 207 is fixedly connected to the side of the positioning plate 203. A connecting rod 209 is fixedly connected to the bottom of the fixing block 205. A positioning rod 210 is fixedly connected to the side of the connecting rod 209. A support rod 211 is fixedly connected to the side of the protective plate 101. An installation plate 212 is fixedly connected to the bottom of the protective plate 101.

[0034] In some examples, the number of support rods 211 is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate 101. The design of the support rods 211 can fix the steel plate 104 and prevent the position of the steel plate 104 from shifting during the welding process.

[0035] The circumferential surface of the fixing rod 207 contacts the inner wall of the slide groove 206. The number of positioning plates 203 is set to two, and they are symmetrical about each other along the vertical central axis of the fixing plate 202. The design of the fixing rod 207 and the slide groove 206 can ensure that the position and angle of the steel plate 104 remain unchanged during welding, thereby improving the welding accuracy and avoiding welding defects caused by the offset of the steel plate 104.

[0036] For example, such as Figures 1-5 As shown, this application uses an electric telescopic rod 201 to drive the fixed plate 202 to move, which in turn drives the positioning plate 203 to move. The positioning plate 203 then drives the fixed rod 207 to move, which in turn pushes the fixed block 205 to rotate along the rotating rod 208. This causes the fixed block 205 to drive the connecting rod 209 to rotate, which in turn drives the positioning rod 210 to rotate. This achieves the function of fixing the steel plate 104 and preventing the position of the steel plate 104 from shifting during welding. After welding is completed, the electric telescopic rod 201 is driven in the opposite direction, causing the fixed plate 202 to move in the opposite direction. At this time, the connecting rod 209 drives the positioning rod 210 to rotate downward, causing the positioning rod 210 to tilt downward to unload the steel plate 104. This achieves the function of fixing the steel plate 104 during welding and unloading the steel plate 104 by tilting downward after welding.

[0037] like Figures 1-5 As shown, it illustrates a high-frequency welding device for H-shaped steel structures in another embodiment of this disclosure, including a fixing device 2 and a feeding structure. The feeding structure includes a support block 213, which is fixedly connected to the bottom of the protective plate 101. A hydraulic cylinder 214 is fixedly connected to the bottom of the support block 213. One end of the hydraulic cylinder 214 is slidably connected to a force rod 215 via a piston, and the other end of the hydraulic cylinder 214 is slidably connected to a hydraulic rod 217 via a piston. A push plate 218 is fixedly connected to the side of the hydraulic rod 217.

[0038] In some examples, a spring 216 is fixedly connected to the side of the hydraulic cylinder 214. The end of the spring 216 away from the hydraulic cylinder 214 is fixedly connected to the circumferential surface of the force rod 215. The design of the spring 216 enables the force rod 215 to automatically reset, reducing manual intervention.

[0039] The spring 216 is initially in a relaxed state, and the steel plate 104 is located on the movement trajectory of the push plate 218. The design of the push plate 218 can realize the function of automatic feeding and reduce manual intervention.

[0040] A robotic arm 103 is provided on the top of the protective plate 101, and a welding structure 105 is provided on the side of the robotic arm 103. The above design can realize the function of automatic welding and improve the efficiency of the entire production line.

[0041] The number of mounting plates 212 is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate 101. The design of the mounting plates 212 can fix the steel plate 104 from multiple directions, ensuring the stability and accuracy of the steel plate 104.

[0042] The number of positioning rods 210 is set to two, and they are symmetrical to each other along the vertical central axis of the protective plate 101. The design of the positioning rods 210 can accurately fix the position of the steel plate 104 and prevent position displacement during the welding process.

[0043] For example, such as Figures 1-5 As shown, after welding is completed, the electric telescopic rod 201 is driven in the reverse direction, causing the fixed plate 202 to move in the reverse direction. The fixed plate 202 presses the force rod 215, causing the force rod 215 to move inward and press the piston inside the hydraulic cylinder 214. The piston inside the hydraulic cylinder 214 pushes the liquid inside it, and the liquid inside the hydraulic cylinder 214 pushes another piston to move. The piston pushes the hydraulic rod 217 to move, and then the hydraulic rod 217 pushes the push plate 218 to move, so that the push plate 218 pushes the steel plate 104 through the positioning rod 210 to complete the unloading, thus realizing the function of automatic unloading.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
