Description

Technical Field

[0001] This invention relates to the technical field of angle steel welding equipment, and more particularly to an automatic welding device for angle steel towers. Background Technology

[0002] Angle steel towers, as an important building structure, are widely used in power transmission lines, bridges, buildings and other fields. In the production process of angle steel towers, the welding of angle steel is a key step. Depending on the usage requirements, it is often necessary to weld the ends of two angle steels at a 45° angle to form a 90° right angle structure. This structure plays a key supporting and connecting role in angle steel towers.

[0003] In traditional welding processes, this step mainly relies on manual operation. Workers need to use right-angle supports to help position the two angle steels and ensure that they can be welded at the correct angle. However, this manual welding method has many shortcomings. First, manual welding is inefficient and cannot meet the needs of large-scale production. Second, due to errors in manual operation, the accuracy of the welded joint is often difficult to guarantee, affecting the welding quality. In addition, manual welding also has problems such as high labor intensity and harsh working environment, which have a certain impact on the health of workers.

[0004] To overcome the shortcomings of traditional welding processes, people began to develop automatic welding equipment to replace manual welding operations. Automatic welding equipment, through preset programs and sensors, can automatically complete steps such as cutting, positioning and welding of angle steel, which greatly improves production efficiency and quality stability. However, despite the significant progress made by automatic welding equipment in welding operations, there are still some problems in material loading and unloading.

[0005] Currently, many automated welding equipment still require manual fixation of angle steel using clamps and right-angle support seats during loading and unloading. This method not only increases the labor intensity of workers, but is also easily affected by the installation accuracy, leading to a decrease in the docking accuracy and thus affecting the welding quality. In addition, manual operation may also increase errors and instabilities in the welding process, further affecting welding efficiency and product quality stability. Summary of the Invention

[0006] The present invention aims to at least partially solve one of the technical problems in the related art.

[0007] Therefore, the purpose of this invention is to provide an automatic welding device for angle steel towers. This invention has an ingenious structural design and outstanding performance. It can automatically feed materials and precisely control the angle steel to move and connect along a preset path, improving processing accuracy and efficiency, ensuring welding quality, and reducing errors. After welding, it can automatically unload materials, further improving work efficiency, reducing manpower burden, avoiding human error and safety hazards, and improving product quality and production stability. It has great market promotion and application value.

[0008] To achieve the above objectives, the present invention proposes an automatic welding device for angle steel towers, comprising:

[0009] The welding component support is triangular in shape, with a pneumatic pusher mechanism, a right-angle positioning guide, and a limiting frame arranged sequentially from the inside out at its top.

[0010] The trigger switch of the pneumatic feeding mechanism is located inside the welding part support;

[0011] The right-angle positioning guide is equipped with feeding wheels on its two outer sides;

[0012] The number of limiting frames is two sets, and they are respectively set on the outer sides of the two outer surfaces of the right-angle positioning guide. The length of the two sets of limiting frames is equal to the length of the two inner sides of the right-angle positioning guide.

[0013] The limiting frame includes a fixed frame and a lifting frame. The fixed frame is integrally formed and installed on the top of the welded part support. The lifting frame is slidably connected to the top of the welded part support and is located on one side of the fixed frame. The space between the two sets of lifting frames forms a first notch to facilitate welding of the vertical surface of the angle steel. The length of the lifting frame and the length of one side of the first notch are equal to the length of the angle steel. One end of the lifting frame penetrates into the interior of the welded part support and is connected to the trigger switch.

[0014] The gap between the right-angle positioning guide and the limiting frame forms a limiting guide groove, which is adapted to the thickness of the angle steel. One set of single sides of the angle steel is located in the limiting guide groove and is slidably connected to the surface of the feeding wheel and the inner wall of the limiting guide groove, respectively. The other set of single sides of the angle steel overlaps the top of the right-angle positioning guide and is slidably connected to the top of the right-angle positioning guide.

[0015] One end of the pneumatic feeding mechanism extends into the limiting guide groove;

[0016] Single drive mechanism: It is installed inside the welded part support and is connected to the feeding wheel and the lifting frame respectively.

[0017] In addition, the automatic welding device for angle steel towers proposed in the above application may also have the following additional technical features:

[0018] Specifically, the pneumatic pushing mechanism includes a triangular seat, a guide cylinder, and a pneumatic telescopic rod. The triangular seat is fixedly connected to the top of the weldment support and is fixedly spaced from the two inner sides of the right-angle positioning guide. The guide cylinder is symmetrically fixedly connected to the two outer sides of the triangular seat near the right-angle positioning guide. The pneumatic telescopic rod is fixedly connected to the inner wall of the guide cylinder, and one end of the pneumatic telescopic rod penetrates into the limiting guide groove. The pneumatic telescopic rod is connected to a trigger switch.

[0019] Specifically, the number of trigger switches is set to two sets. The two sets of trigger switches are used to control the opening and closing of the pneumatic telescopic rods on the two outer surfaces of the triangular seat respectively. The trigger switches also include single-control switches set on the surface of the welded part bracket. The single-control switches can control the opening and closing of the corresponding connected trigger switches. Both the trigger switches and the single-control switches are rocker switches.

[0020] Specifically, the lifting frame includes a stop, a reciprocating screw, a limiting guide rod, a mounting base, and a cam shaft. An opening slot is provided at the top of the welded component support corresponding to the position of the stop. The stop is vertically slidably connected to the inner wall of the opening slot. The reciprocating screw is rotatably connected to the bottom wall of the opening slot. One end of the reciprocating screw penetrates into the welded component support and is connected to the single-drive mechanism. The stop is threadedly connected to the outer surface of the reciprocating screw. The limiting guide rods are symmetrically vertically slidably connected to the bottom wall of the opening slot and located outside the reciprocating screw. One end of each of the two sets of limiting guide rods is fixedly connected to the bottom of both ends of the stop. The other ends of each set of limiting guide rods penetrate into the welded component support. One end of one set of limiting guide rods penetrating into the welded component support is fixedly connected to the surface of the mounting base. The cam shaft is threadedly connected to the surface of the mounting base and slidably connected to the surface of the trigger switch.

[0021] Specifically, the single-drive mechanism includes a dual-axis motor, a worm gear, a one-way transmission, a first transmission rod, a second transmission rod, a third transmission rod, a fourth transmission rod, a first bevel gear, a first worm wheel, a worm section, a second worm wheel, a second bevel gear, and a third bevel gear, wherein...

[0022] The dual-axis motor is fixedly connected to the inner wall of the welded component support. The worm gears are symmetrically rotatably connected to the inner wall of the welded component support and located outside the dual-axis motor. One end of each of the two sets of worm gears is connected to the output end of the dual-axis motor via a one-way transmission. The first and second transmission rods are rotatably connected to the inner wall of the welded component support, located on the top and bottom sides of one set of worm gears, respectively. A third and fourth transmission rod are rotatably connected to one side of the first and second transmission rods, respectively. First bevel gears are respectively provided at positions corresponding to the first and third transmission rod ends and at positions corresponding to the fourth transmission rod ends. The first and second transmission rods are respectively provided with first worm gears on their other end surfaces, which mesh with the two sets of worms. The worm portions are uniformly integrally formed on the surfaces of the first and third transmission rods. The second worm gear is uniformly rotatably connected to the inner wall of the welded part bracket and meshes with the worm portions. One end of the central shaft of the second worm gear is fixedly connected to one end of the central shaft of the feeding wheel. The second bevel gear is fixedly connected to the surfaces of the second and fourth transmission rods and corresponds to the position of the end of the reciprocating screw that penetrates into the welded part bracket. The third bevel gear is fixedly connected to the surface of the end of the reciprocating screw that penetrates into the welded part bracket and meshes with the second bevel gear.

[0023] Specifically, the two sets of one-way actuators have opposite transmission directions, and both sets of one-way actuators are ratchet-type one-way actuators.

[0024] Specifically, the top of the right-angle positioning guide is uniformly provided with auxiliary wheels, and the top of the right-angle positioning guide is integrally formed with an L-shaped limiting part located inside the auxiliary wheels. The installation area of ​​the auxiliary wheels is adapted to the length of the two inner sides of the right-angle positioning guide. The length of the L-shaped limiting part is less than the length of the two inner sides of the right-angle positioning guide. The space between the two sets of L-shaped limiting parts forms a second notch that facilitates welding of the angle steel to the horizontal plane.

[0025] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. With its reasonable structural design, this invention demonstrates excellent performance and practicality. Its core advantage lies in its ability to achieve automatic feeding. Through the cooperation of right-angle positioning guide, feeding wheel, auxiliary wheel, L-shaped limiting part, limiting frame and limiting guide groove, the angle steel is precisely controlled to move along the preset path and achieve precise docking at the designated position. This function undoubtedly greatly improves the accuracy and efficiency of processing, lays a solid foundation for ensuring welding quality, and also effectively reduces errors in the processing process.

[0028] 2. This invention also enables automatic unloading after welding. Through the cooperation of a pneumatic pusher mechanism, a trigger switch, and a lifting frame, the welded angle steel can be automatically removed from the support. This fully automated unloading operation design not only significantly improves overall work efficiency but also greatly reduces the labor intensity of operators, allowing them to focus on other more critical aspects, thereby further improving overall production efficiency. In addition, the automated unloading operation effectively avoids errors and safety hazards caused by human factors. This design undoubtedly further improves product quality and production stability.

[0029] 3. The lifting frame in this invention is designed to be raised and lowered. The lifting frame has dual functions and exhibits high practicality. When it is raised, it can accurately limit and guide the angle steel to ensure the stability and accuracy of the processing. When the lifting frame is lowered, it provides a smooth unloading channel for the angle steel after welding, which greatly facilitates subsequent operations. The overall use effect is significant.

[0030] 4. This invention cleverly sets up two sets of trigger switches, which can control the opening and closing of the pneumatic telescopic rods located on the two outer surfaces of the triangular base respectively. This innovative layout allows the welded angle steel to be unloaded in two different directions, greatly enhancing the flexibility and practicality of the equipment. More advancedly, the equipment is also equipped with a single-control switch, which can independently control the opening and closing of each set of trigger switches. This design ensures that in actual operation, only one set of trigger switches can be turned on as needed, thereby accurately realizing the unloading operation in the set direction. This design not only improves the stability of operation, but also avoids unnecessary energy waste, making the overall effect of the equipment more significant.

[0031] 5. The present invention also includes a single-drive mechanism, which is specifically designed to precisely control the independent operation of the feeding wheel and the lifting frame. It uses a single power source, which not only ensures stable and reliable performance, but also simplifies the control system and makes operation more convenient. In addition, this design effectively reduces production costs and facilitates subsequent maintenance and repair. Attached Figure Description

[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0045] The following describes an automatic welding device for angle steel towers according to an embodiment of the present invention, with reference to the accompanying drawings.

[0046] like Figures 1-4 As shown, an automatic welding device for angle steel towers according to an embodiment of the present invention includes:

[0047] Welding component support 1: It is triangular in shape, and its top is equipped with, from the inside out, a pneumatic pusher mechanism 2, a right-angle positioning guide 3, and a limiting frame 4.

[0048] The trigger switch 24 of the pneumatic feeding mechanism 2 is installed inside the welding part support 1;

[0049] The two outer sides of the right-angle positioning guide 3 are respectively equipped with loading wheels 31;

[0050] There are two sets of limiting brackets 4, which are respectively set on the outer sides of the two outer sides of the right-angle positioning guide 3. The lengths of the two sets of limiting brackets 4 are equal to the lengths of the two inner sides of the right-angle positioning guide 3.

[0051] The limiting frame 4 includes a fixed frame 41 and a lifting frame 42. The fixed frame 41 is integrally formed and set on the top of the welded part support 1. The lifting frame 42 is slidably connected to the top of the welded part support 1 and is located on one side of the fixed frame 41. The space between the two sets of lifting frames 42 forms a first notch 43 that facilitates welding of the vertical surface of the angle steel. The length of the lifting frame 42 and the length of one side of the first notch 43 are equal to the length of the angle steel. One end of the lifting frame 42 penetrates into the interior of the welded part support 1 and is connected to the trigger switch 24.

[0052] The gap between the right-angle positioning guide 3 and the limiting frame 4 forms a limiting guide groove 32, which is adapted to the thickness of the angle steel. One set of single sides of the angle steel is located in the limiting guide groove 32 and is slidably connected to the surface of the feeding wheel 31 and the inner wall of the limiting guide groove 32 respectively. The other set of single sides of the angle steel overlaps the top of the right-angle positioning guide 3 and is slidably connected to the top of the right-angle positioning guide 3.

[0053] One end of the pneumatic feeding mechanism 2 extends into the limiting guide groove 32;

[0054] Single drive mechanism 5: It is installed inside the welded part bracket 1 and is connected to the loading wheel 31 and the lifting frame 42 respectively.

[0055] It should also be noted that the welded bracket 1 is also connected to two sets of conveyor belt mechanisms (not shown in the figure). The conveyor belt mechanism continuously transports the cut angle steel to the two sets of limit guide grooves 32. The conveyor belt mechanism is connected to an external controller. The conveying speed of the conveyor belt mechanism is adapted to the running speed of the single drive mechanism 5 to ensure smooth operation.

[0056] Specifically, this invention, with its rational structural design, exhibits superior performance and practicality. Its core advantage lies in its ability to automatically feed materials. Through the coordinated operation of the right-angle positioning guide 3, feeding wheel 31, auxiliary wheel 33, L-shaped limiting part 34, limiting frame 4, and limiting guide groove 32, the angle steel is precisely controlled to move along a preset path and achieve accurate docking at a designated position. This function undoubtedly greatly improves the accuracy and efficiency of processing, laying a solid foundation for ensuring welding quality, while also effectively reducing errors during processing. This invention can also achieve automatic unloading after welding, through the pneumatic pushing mechanism 2, trigger switch 24, and lifting mechanism. The lifting frame 42 works in conjunction with each other to automatically remove the welded angle steel from the support. This fully automated unloading operation design not only significantly improves overall work efficiency but also greatly reduces the labor intensity of operators, allowing them to focus on other more critical processes, thereby further improving overall production efficiency. Furthermore, the automated unloading operation effectively avoids errors and safety hazards caused by human factors. This design undoubtedly further improves product quality and production stability. The lifting frame 42 in this invention is height-adjustable and has dual functions, demonstrating high practicality. In the raised state, it can move the angle steel... Precise positioning and guidance ensure the stability and accuracy of the processing. When the lifting frame 42 descends, it provides a smooth unloading channel for the welded angle steel, greatly facilitating subsequent operations. The overall performance is remarkable. This invention cleverly incorporates two sets of trigger switches 24, which can control the opening and closing of the pneumatic telescopic rods 23 located on the two outer surfaces of the triangular base 21. This innovative layout allows the welded angle steel to be unloaded in two different directions, greatly enhancing the flexibility and practicality of the equipment. More advancedly, the equipment is also equipped with a single-control switch 241, which can independently activate each set of trigger switches 24. The closed-loop control design ensures that, during actual operation, only one set of trigger switches 24 can be activated as needed to precisely achieve the unloading operation in the set direction. This design not only improves the stability of operation but also avoids unnecessary energy waste, making the overall effect of the equipment more significant. The invention also includes a single-drive mechanism 5, which is specifically designed to precisely control the independent operation of the loading wheel 31 and the lifting frame 42. It uses a single power source, which is not only stable and reliable but also simplifies the control system, making operation more convenient. In addition, this design effectively reduces production costs and facilitates subsequent maintenance and repair.

[0057] In operation, the single-drive mechanism 5 operates according to instructions and simultaneously drives the loading wheel 31 to rotate a set number of revolutions. The rotation of the loading wheel 31 synchronously drives the two sets of angle steels within the limiting guide groove 32 to move until their ends are precisely aligned, thus realizing the loading operation. The position of the aligned angle steels corresponds to the position of the lifting frame 42. At this time, the lifting frame 42 is in the raised state, which guides and limits the angle steels. Then, the automatic welding equipment performs 45° oblique welding on the angle steels through the welding head. After the welding is completed, the single-drive mechanism 5 operates again according to instructions and synchronously drives the lifting frame 42 to descend, leaving a channel for the angle steels to be unloaded. When the lifting frame 42 descends to the set height, it triggers the trigger switch 24 in the pneumatic pushing mechanism 2 to operate. The operation of the trigger switch 24 controls the pneumatic pushing mechanism. The pneumatic telescopic rod 23 in section 2 extends to realize the unloading operation. After the angle steel is pushed out, the single drive mechanism 5 drives the lifting frame 42 to rise and reset. During the rising process of the lifting frame 42, the trigger switch 24 in the pneumatic pushing mechanism 2 is triggered again. The operation of the trigger switch 24 controls the pneumatic telescopic rod 23 in the pneumatic pushing mechanism 2 to reset, which is convenient for the next pushing operation. Then, the single drive mechanism 5 runs according to the instruction and drives the loading wheel 31 to rotate a set number of times. The rotation of the loading wheel 31 drives the two sets of angle steel in the limiting guide groove 32 to move until their ends are precisely connected to realize the loading operation. At the same time, the two sets of conveyor belt mechanisms (not shown in the figure) run synchronously and transport the new angle steel to the limiting guide groove 32 to realize the loading operation. The effect is good.

[0058] In one embodiment of the present invention, such as Figure 2 As shown, the pneumatic pusher mechanism 2 includes a triangular seat 21, a guide cylinder 22, and a pneumatic telescopic rod 23. The triangular seat 21 is fixedly connected to the top of the welded part bracket 1 and is fixedly spaced from the two inner sides of the right-angle positioning guide 3. The guide cylinder 22 is symmetrically fixedly connected to the two outer surfaces of the triangular seat 21 near the right-angle positioning guide 3. The pneumatic telescopic rod 23 is fixedly connected to the inner wall of the guide cylinder 22. One end of the pneumatic telescopic rod 23 passes through the limiting guide groove 32. The pneumatic telescopic rod 23 is connected to the trigger switch 24.

[0059] Specifically, the structure and connection relationship of the pneumatic pusher mechanism 2 are further explained. The triangular base 21, as the basic support structure of the pneumatic pusher mechanism 2, is fixedly connected to the top of the welding part bracket 1. The distance between the triangular base 21 and the two inner sides of the right-angle positioning guide 3 is fixed to ensure that the extended length of the pneumatic telescopic rod 23 is equal, so as to further ensure a constant pushing force. The guide cylinder 22 is symmetrically fixedly connected to the two outer surfaces of the triangular base 21 near the right-angle positioning guide 3, and is used to support and guide the pneumatic telescopic rod 23. The design of the guide cylinder 22 enables the pneumatic telescopic rod 23 to perform stable telescopic movement inside it. The pneumatic telescopic rod 23 achieves telescopic movement through air pressure, which is used to push the angle steel out to realize the unloading operation. One end of the pneumatic telescopic rod 23 passes through the limiting guide groove 32 to ensure the stability and accuracy of the angle steel during the welding process. At the same time, the pneumatic telescopic rod 23 is connected to the trigger switch 24 to realize automated control.

[0060] After the welding operation, the trigger switch 24 is triggered, and the trigger switch 24 controls the pneumatic telescopic rod 23 to move, pushing the angle steel out of the limiting guide groove 32 and onto the outside of the welding part bracket 1, realizing the unloading operation. When the trigger switch 24 is triggered again, the pneumatic telescopic rod 23 is reset, making it convenient for the next pushing operation.

[0061] In one embodiment of the present invention, such as Figures 1-3 As shown, the number of trigger switches 24 is set to two sets. The two sets of trigger switches 24 are used to control the opening and closing of the pneumatic telescopic rods 23 on the two outer surfaces of the triangular seat 21 respectively. The trigger switches 24 also include single-control switches 241 set on the surface of the welded support 1. The opening and closing of the corresponding trigger switches 24 can be controlled by the single-control switches 241. Both the trigger switches 24 and the single-control switches 241 are rocker switches.

[0062] It should be noted that when one end of the trigger switch 24 is pressed, that is, the trigger switch 24 is activated for the first time, controlling the pneumatic telescopic rod 23 to extend. When the other end of the trigger switch 24 is pressed, that is, the trigger switch 24 is activated for the second time, controlling the pneumatic telescopic rod 23 to reset.

[0063] It is understandable that the single-pole switch 241 is installed on the power line of the trigger switch 24.

[0064] Specifically, the number and structure of the trigger switches 24 are further explained. By cleverly setting two sets of trigger switches 24, the opening and closing of the pneumatic telescopic rods 23 located on the two outer surfaces of the triangular base 21 can be controlled separately. This innovative layout allows the welded angle steel to be unloaded in two different directions, greatly enhancing the flexibility and practicality of the equipment. More advancedly, the equipment is also equipped with a single-control switch 241, which can independently control the opening and closing of each set of trigger switches 24. This design ensures that in actual operation, only one set of trigger switches 24 can be turned on as needed, thereby accurately realizing the unloading operation in the set direction. This design not only improves the stability of operation but also avoids unnecessary energy waste, making the overall effect of the equipment more significant.

[0065] In one embodiment of the present invention, such as Figure 3 As shown, the lifting frame 42 includes a stop 421, a reciprocating screw 422, a limiting guide rod 423, a mounting base 424, and a cam 425. An opening slot 420 is provided at the top of the welded component support 1, corresponding to the position of the stop 421. The stop 421 is vertically slidably connected to the inner wall of the opening slot 420. The reciprocating screw 422 is rotatably connected to the bottom wall of the opening slot 420. One end of the reciprocating screw 422 penetrates into the interior of the welded component support 1 and is connected to the single-drive mechanism 5. The stop 421 is threadedly connected to the outside of the reciprocating screw 422. On the surface, the limiting guide rods 423 are symmetrically and vertically slidably connected to the bottom wall of the opening slot 420 and located outside the reciprocating screw 422. One end of each of the two sets of limiting guide rods 423 is fixedly connected to the bottom of both ends of the stop 421, and the other end of each of the two sets of limiting guide rods 423 passes through the inside of the welded part bracket 1. One end of one set of limiting guide rods 423 that passes through the inside of the welded part bracket 1 is fixedly connected to the surface of the mounting base 424. The convex shaft 425 is threadedly connected to the surface of the mounting base 424 and slidably connected to the surface of the trigger switch 24.

[0066] Specifically, the structure and connection relationship of the lifting frame 42 will be further explained. The lifting frame 42 has dual functions and exhibits extremely high practicality. When it is in the rising state, it can accurately limit and guide the angle steel, ensuring the stability and accuracy of the processing. When the lifting frame 42 is lowered, it provides a smooth unloading channel for the welded angle steel, greatly facilitating subsequent operations, and the overall use effect is remarkable.

[0067] In use, the single-drive mechanism 5 synchronously drives the reciprocating screw 422 to rotate. The rotation of the reciprocating screw 422 first synchronously drives the stop 421, the limit guide rod 423, and the cam shaft 425 to descend. When the stop 421 moves down into the opening slot 420 and is lower than the top of the welded part bracket 1, the angle steel unloading channel is opened, and the cam shaft 425 will trigger the trigger switch 24 to run for the first time. The first run of the trigger switch 24 controls the pneumatic telescopic rod 23 to extend, realizing the unloading operation. When the reciprocating screw 422 rotates... When the rotating drive baffle 421, limit guide rod 423 and cam shaft 425 rise synchronously, and the top of the baffle 421 has not yet moved out of the opening slot 420, the cam shaft 425 will trigger the trigger switch 24 to run for the second time. The second run of the trigger switch 24 controls the pneumatic telescopic rod 23 to reset, preparing for the next material pushing operation. When the top of the baffle 421 rises to the same level as the top of the fixed frame 41, the single drive mechanism 5 stops running, the position of the baffle 421 is fixed, and it plays a guiding and limiting role for the angle steel.

[0068] In one embodiment of the present invention, such as Figures 3-4 As shown, the single-drive mechanism 5 includes a dual-shaft motor 51, a worm gear 52, a one-way transmission 53, a first transmission rod 54, a second transmission rod 55, a third transmission rod 56, a fourth transmission rod 57, a first bevel gear 58, a first worm wheel 59, a worm section 510, a second worm wheel 511, a second bevel gear 512, and a third bevel gear 513, wherein...

[0069] A dual-axis motor 51 is fixedly connected to the inner wall of the welded component support 1. Worms 52 are symmetrically rotatably connected to the inner wall of the welded component support 1 and located outside the dual-axis motor 51. One end of each of the two sets of worms 52 is connected to the output end of the dual-axis motor 51 via a one-way transmission 53. A first transmission rod 54 and a second transmission rod 55 are rotatably connected to the inner wall of the welded component support 1, located on the top and bottom sides of one set of worms 52, respectively. A third transmission rod 56 and a fourth transmission rod 57 are rotatably connected to one side of the first transmission rod 54 and the second transmission rod 55, respectively. First bevel gears 58 are respectively provided at positions corresponding to the first transmission rod 54 and the third transmission rod 56, and at positions corresponding to the second transmission rod 55 and the fourth transmission rod 57, and are mutually... The first transmission rod 54 and the second transmission rod 55 are respectively provided with first worm gears 59 on their other end surfaces, and mesh with two sets of worms 52. The worm part 510 is uniformly integrally formed on the surface of the first transmission rod 54 and the third transmission rod 56. The second worm gear 511 is uniformly rotatably connected to the inner wall of the welded part bracket 1 and meshes with the worm part 510. One end of the central shaft of the second worm gear 511 is fixedly connected to one end of the central shaft of the feeding wheel 31. The second bevel gear 512 is fixedly connected to the surface of the second transmission rod 55 and the fourth transmission rod 57, and corresponds to the position of the end of the reciprocating screw 422 that penetrates into the interior of the welded part bracket 1. The third bevel gear 513 is fixedly connected to the surface of the end of the reciprocating screw 422 that penetrates into the interior of the welded part bracket 1 and meshes with the second bevel gear 512.

[0070] It should be noted that the dual-axis motor 51 is connected to an external controller via a bus system to transmit data and receive control commands.

[0071] It should also be noted that an encoder is fixedly connected to the surface of the dual-axis motor 51, which is used to detect the number of rotations of the dual-axis motor 51 in real time.

[0072] Specifically, the structure and connection relationship of the single drive mechanism 5 will be further explained. The single drive mechanism 5 is specially designed to precisely control the independent operation of the loading wheel 31 and the lifting frame 42. It adopts a single power source, which not only has stable and reliable performance, but also simplifies the control system and makes operation more convenient. In addition, this design effectively reduces production costs and facilitates subsequent maintenance and repair work.

[0073] During use, the dual-axis motor 51 rotates forward or backward according to the received instructions. When the dual-axis motor 51 rotates forward, it drives the worm 52, which is matched with the position of the first transmission rod 54, to rotate only through the one-way transmission 53. This rotation is synchronized by the first worm wheel 59, which drives the first transmission rod 54 to rotate. Subsequently, the first transmission rod 54 drives the third transmission rod 56 to rotate synchronously through the meshing of the first bevel gear 58. The rotation of the first transmission rod 54 and the third transmission rod 56 also synchronously drives the worm portion 510 on their surfaces to rotate, which in turn drives the second worm wheel 511 and the feeding wheel 31 to rotate, thereby realizing the synchronous feeding operation of the two sets of angle steel.

[0074] When the dual-axis motor 51 reverses, it drives the worm gear 52, which matches the position of the second transmission rod 55, to rotate only through the one-way transmission 53. This rotation also drives the second transmission rod 55 to rotate through the synchronizing action of the first worm wheel 59. Then, the second transmission rod 55 drives the fourth transmission rod 57 to rotate synchronously through the meshing of the first bevel gear 58. The rotation of the second transmission rod 55 and the fourth transmission rod 57 synchronously drives the second bevel gear 512 on their surfaces to rotate, which in turn drives the third bevel gear 513 and the reciprocating screw 422 to rotate, realizing the synchronous lifting and lowering operation of the two sets of baffles 421. The lifting and lowering of the baffles 421 synchronously drives the limit guide rod 423, the mounting base 424 and the cam shaft 425 to lift and lower. During the lifting and lowering of the cam shaft 425, it will trigger the trigger switch 24 twice. When it is triggered for the first time, it controls the pneumatic telescopic rod 23 to extend to realize the unloading operation; when it is triggered for the second time, it controls the pneumatic telescopic rod 23 to reset, preparing for the next pushing operation.

[0075] In one embodiment of the present invention, such as Figures 3-4 As shown, the two sets of one-way actuators 53 have opposite transmission directions, and both sets of one-way actuators 53 are ratchet-type one-way actuators.

[0076] Specifically, the transmission direction and type of the one-way drive 53 are further defined. By precisely defining the transmission direction, the one-way drive 53 ensures that the dual-axis motor 51 can drive the loading wheel 31 and the lifting frame 42 independently and efficiently, without interfering with each other. This design not only greatly enhances the stability and reliability of the system, but also greatly improves the overall operational efficiency.

[0077] In one embodiment of the present invention, such as Figure 1As shown, auxiliary wheels 33 are evenly arranged on the top of the right-angle positioning guide 3. An L-shaped limiting part 34 is integrally formed on the top of the right-angle positioning guide 3 and is located inside the auxiliary wheels 33. The installation area of ​​the auxiliary wheels 33 is adapted to the length of the two inner sides of the right-angle positioning guide 3. The length of the L-shaped limiting part 34 is less than the length of the two inner sides of the right-angle positioning guide 3. The space between the two sets of L-shaped limiting parts 34 forms a second notch 35 that facilitates welding of the angle steel to the horizontal plane.

[0078] Specifically, the auxiliary wheel 33 is configured to reduce friction and ensure that the angle steel can be transported smoothly and without obstruction. At the same time, the auxiliary wheel 33 and the L-shaped limiting part 34 work together to provide stable support and precise positioning for the top and bottom of one side of the angle steel, thereby greatly improving the docking accuracy of the angle steel. In addition, the specially designed second notch 35 provides a convenient tool entry and exit channel for the welding head when performing 45° welding operations, which not only enhances practicality but also significantly optimizes the use effect.

[0079] In summary, the automatic angle steel welding device for angle steel towers according to embodiments of the present invention has an ingenious structural design and outstanding performance. It can automatically feed materials and precisely control the angle steel to move and connect along a preset path, improving processing accuracy and efficiency, ensuring welding quality, reducing errors, and automatically unloading materials after welding, further improving work efficiency, reducing manpower burden, avoiding human error and safety hazards, improving product quality and production stability, and has great market promotion and application value.
