Description

Technical Field

[0001] The invention relates to the technical field of angle steel welding equipment, and in particular to an automatic welding device for angle steel tower angle steel. Background Art

[0002] Angle steel towers are an important building structure and 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. According to the use requirements, it is often necessary to weld the ends of two angle steels at an angle of 45° to form a 90° right-angle structure. This structure plays a key supporting and connecting role in the angle steel tower.

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

[0004] In order to overcome the shortcomings of traditional welding processes, people began to develop automatic welding equipment to replace manual welding operations. Automatic welding equipment can automatically complete the cutting, positioning and welding of angle steels through preset programs and sensors, greatly improving production efficiency and quality stability. However, although automatic welding equipment has made significant progress in welding operations, there are still some problems in loading and unloading.

[0005] At present, many automatic welding equipment still require manual work to fix the angle steel through clamps and right-angle support seats when loading and unloading. This method not only increases the labor intensity of workers, but is also easily affected by the installation accuracy, resulting in reduced docking accuracy, which in turn affects the welding quality. In addition, manual operation may also lead to increased errors and unstable factors in the welding process, further affecting the welding efficiency and the stability of product quality.

[0019] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0020] An automatic welding device for angle steel tower angle steel according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0021] like Figure 1-Figure 4 As shown, an automatic welding device for angle steel tower angle steel according to an embodiment of the present invention comprises: Welding bracket 1: Its shape is triangular, and its top is provided with pneumatic push mechanism 2, right angle positioning guide frame 3 and limit frame 4 from inside to outside, among which, The trigger switch 24 of the pneumatic pushing mechanism 2 is arranged in the welding part bracket 1; The two outer sides of the right-angle positioning guide frame 3 are respectively provided with feeding wheels 31; There are two groups of limit frames 4, which are respectively arranged outside the two outer side surfaces of the right-angle positioning guide frame 3, and the lengths of the two groups of limit frames 4 are respectively equal to the lengths of the two inner sides of the right-angle positioning guide frame 3; The limiting frame 4 includes a fixing frame 41 and a lifting frame 42. The fixing frame 41 is integrally formed and arranged on the top of the welding component bracket 1. The lifting frame 42 is slidably connected to the top of the welding component bracket 1 and is located on one side of the fixing frame 41. The space between the two sets of lifting frames 42 forms a first notch portion 43 for facilitating the 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 portion 43 are equal to the length of the angle steel. One end of the lifting frame 42 penetrates into the interior of the welding component bracket 1 and is connected to the trigger switch 24. The gap between the right-angle positioning guide frame 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 frame 3 and is slidably connected to the top of the right-angle positioning guide frame 3. One end of the pneumatic pushing mechanism 2 penetrates into the limiting guide groove 32; Single drive mechanism 5: is arranged inside the welding component bracket 1, and is connected to the feeding wheel 31 and the lifting frame 42 respectively.

[0022] It should also be noted that the welding part bracket 1 is also connected to two sets of conveyor belt mechanisms (not shown in the figure), which continuously convey the cut angle steels to the two sets of limiting guide grooves 32. The conveyor belt mechanism is connected to an external controller, and the conveying speed of the conveyor belt mechanism is adapted to the operating speed of the single-drive mechanism 5 to ensure smooth operation.

[0023] Specifically, the present invention has demonstrated excellent performance and practicality with its reasonable structural design. Its core advantage lies in the ability to realize automatic loading. Through the cooperation of the right-angle positioning guide frame 3, the loading wheel 31, the auxiliary wheel 33, the L-shaped limit portion 34, the limit frame 4 and the limit guide groove 32, the angle steel is accurately controlled to move along the preset path and achieve precise docking at the specified position. This function undoubtedly greatly improves the accuracy and efficiency of processing, lays a solid foundation for ensuring the quality of welding, and effectively reduces the error in the processing process. After the welding is completed, the present invention can also realize automatic unloading, through the pneumatic pushing mechanism 2, the trigger switch 24 and the lifting mechanism. The brackets 42 cooperate with each other to automatically remove the welded angle steel from the bracket. This fully automated unloading operation design not only significantly improves the overall work efficiency, but also greatly reduces the labor intensity of operators, allowing them to focus on other more critical links, thereby further improving the overall production efficiency. In addition, the automated unloading operation also effectively avoids errors and safety hazards caused by human factors. This design undoubtedly further improves the quality of the product and the stability of production. The lifting frame 42 in the present invention is a liftable design. The lifting frame 42 has dual functions and shows extremely high practicality. When it is in the rising state, it can lift the angle steel. The invention can perform precise limiting and guiding to ensure the stability and accuracy of the processing process. When the lifting frame 42 descends, it provides a smooth unloading channel for the angle steel after welding, which greatly facilitates the subsequent operation and has a significant overall use effect. The present invention cleverly sets two groups of trigger switches 24, which can respectively control the opening and closing of the pneumatic telescopic rods 23 located on the two outer sides of the triangular seat 21. This innovative layout enables the angle steel after welding to be unloaded in two different directions, which greatly enhances the flexibility and practicality of the equipment. More advanced is that the equipment is also equipped with a single-control switch 241, which can independently start and close each group of trigger switches 24. Closed control, this design ensures that in the actual operation process, only one set of trigger switches 24 can be turned on as needed, so as to accurately realize the unloading operation in the set direction. This design not only improves the stability of the operation, but also avoids unnecessary energy waste, making the use effect of the entire equipment more significant. The present invention also provides a single-drive mechanism 5, which is specially designed to accurately 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, making the operation more convenient. In addition, this design effectively reduces the production cost and facilitates subsequent maintenance and repair work.

[0024] When in use, the single-drive mechanism 5 operates according to the instruction, and synchronously drives the feeding wheel 31 to rotate the set number of circles. The rotation of the feeding wheel 31 synchronously drives the two groups of angle steels in the limiting guide groove 32 to move until their ends are accurately docked to realize the feeding operation. The position of the angle steel after docking corresponds to the position of the lifting frame 42. At this time, the lifting frame 42 is in a raised state, which plays a guiding and limiting role for the angle steel. Then the automatic welding equipment performs a 45° oblique welding on the angle steel through the welding head. After the welding is completed, the single-drive mechanism 5 operates again according to the instruction, and synchronously drives the lifting frame 42 to descend, leaving a channel for the angle steel 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, and the trigger switch 24 operates to control the pneumatic pushing mechanism 2 is pushed out 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 to operate. The trigger switch 24 operates to control 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 operates according to the instruction, and synchronously drives the feeding wheel 31 to rotate a set number of circles. The rotation of the feeding wheel 31 synchronously drives the two groups of angle steels in the limiting guide groove 32 to move until their ends are accurately docked to realize the feeding operation. At the same time, the two groups of conveyor belt mechanisms (not shown in the figure) operate synchronously and convey the new angle steel to the limiting guide groove 32 to realize the feeding operation, and the use effect is good.

[0025] In one embodiment of the present invention, Figure 2 As shown, the pneumatic pushing 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 welding part bracket 1 and is fixed at a distance from the two inner sides of the right-angle positioning guide frame 3. The guide cylinder 22 is symmetrically fixedly connected to the two outer sides of the triangular seat 21 close to the right-angle positioning guide frame 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 penetrates into the limiting guide groove 32, wherein the pneumatic telescopic rod 23 is connected to the trigger switch 24.

[0026] Specifically, the structure and connection relationship of the pneumatic pusher mechanism 2 are further explained. The triangular seat 21 is used as the basic support structure of the pneumatic pusher mechanism 2. It is fixedly connected to the top of the welding part bracket 1 and is fixed at a distance from the two inner sides of the right-angle positioning guide frame 3 to ensure that the pneumatic telescopic rod 23 extends to an equal length to further ensure a constant pushing force. The guide cylinder 22 is symmetrically fixedly connected to the two outer sides of the triangular seat 21 close to the right-angle positioning guide frame 3 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 is driven by air pressure to achieve telescopic movement, which is used to push the angle steel out and realize the unloading operation. One end of the pneumatic telescopic rod 23 penetrates into the limiting guide groove 32 to ensure the stability and accuracy of the angle steel during welding. At the same time, the pneumatic telescopic rod 23 is connected to the trigger switch 24 to achieve automatic control.

[0027] After the welding operation, the trigger switch 24 is triggered, and the trigger switch 24 controls the operation of the pneumatic telescopic rod 23, pushing the angle steel out of the limiting guide groove 32 and dropping it outside the welding part bracket 1 to realize the unloading operation. When the trigger switch 24 is triggered again, the pneumatic telescopic rod 23 is reset to facilitate the next pushing operation.

[0028] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the number of trigger switches 24 is set to two groups, and the two groups of trigger switches 24 are used to control the opening and closing of the pneumatic telescopic rods 23 on the two outer sides of the triangular seat 21 respectively. The trigger switch 24 also includes a single-control switch 241 arranged on the surface of the welding part bracket 1, and the opening and closing of the corresponding connected trigger switch 24 can be controlled by the single-control switch 241, wherein the trigger switch 24 and the single-control switch 241 are both boat-shaped switches.

[0029] It should be noted that when one end of the trigger switch 24 is pressed, that is, the trigger switch 24 operates for the first time, the pneumatic telescopic rod 23 is controlled to extend, and when the other end of the trigger switch 24 is pressed, that is, the trigger switch 24 operates for the second time, the pneumatic telescopic rod 23 is controlled to reset.

[0030] It can be understood that the single-control switch 241 is arranged on the power-on circuit of the trigger switch 24 .

[0031] Specifically, the number and structure of the trigger switches 24 are further explained. By cleverly setting two groups of trigger switches 24, the opening and closing of the pneumatic telescopic rods 23 located on the two outer sides of the triangular seat 21 can be controlled respectively. This innovative layout enables the angle steel after welding to be unloaded in two different directions, greatly enhancing the flexibility and practicality of the equipment. More advanced is that the equipment is also equipped with a single control switch 241, which can independently control the opening and closing of each group of trigger switches 24. This design ensures that in the actual operation process, only one group of trigger switches 24 can be turned on as needed, so as to accurately realize the unloading operation in the set direction. This design not only improves the stability of the operation, but also avoids unnecessary energy waste, making the use effect of the entire equipment more significant.

[0032] In one embodiment of the present invention, Figure 3 As shown, the lifting frame 42 includes a stop frame 421, a reciprocating screw rod 422, a limiting guide rod 423, a mounting seat 424 and a convex shaft 425. An open groove 420 is provided at the top of the welding component bracket 1 corresponding to the position of the stop frame 421. The stop frame 421 is vertically slidably connected to the inner side wall of the open groove 420. The reciprocating screw rod 422 is rotatably connected to the inner bottom wall of the open groove 420. One end of the reciprocating screw rod 422 penetrates into the interior of the welding component bracket 1 and is connected to the single-drive mechanism 5. The stop frame 421 is threadedly connected to the outer side of the reciprocating screw rod 422. The limiting guide rods 423 are symmetrically and vertically slidably connected to the bottom wall of the opening groove 420 and are located on the outside of the reciprocating screw rod 422. One end of the two groups of limiting guide rods 423 are respectively fixedly connected to the bottom of the two ends of the blocking frame 421, and the other ends of the two groups of limiting guide rods 423 respectively penetrate into the interior of the welding part bracket 1. One end surface of one group of limiting guide rods 423 that penetrates into the interior of the welding part bracket 1 is fixedly connected to a mounting seat 424, and the convex shaft 425 is threadedly connected to the surface of the mounting seat 424 and is slidably connected to the surface of the trigger switch 24.

[0033] Specifically, the structure and connection relationship of the lifting frame 42 are further described. The lifting frame 42 has dual functions and is extremely practical. When it is in the ascending state, it can accurately limit and guide the angle steel to ensure the stability and accuracy of the processing process. When the lifting frame 42 is descending, it provides a smooth material discharge channel for the angle steel after welding, greatly facilitating subsequent operations, and the overall use effect is significant.

[0034] When in use, the single-drive mechanism 5 operates synchronously to drive the reciprocating screw 422 to rotate. The rotation of the reciprocating screw 422 first synchronously drives the retaining frame 421, the limiting guide rod 423 and the convex shaft 425 to descend. When the retaining frame 421 moves down to the inside of the opening groove 420 and is lower than the top of the welding part bracket 1, the angle steel unloading channel is left, and the convex shaft 425 will trigger the trigger switch 24 to operate for the first time. The trigger switch 24 operates for the first time to control the pneumatic telescopic rod 23 to extend to realize the unloading operation. When the reciprocating screw 422 rotates, The rotation drives the retaining frame 421, the limiting guide rod 423 and the convex shaft 425 to rise synchronously, and when the top of the retaining frame 421 has not moved out of the opening groove 420, the convex shaft 425 will trigger the trigger switch 24 to operate for the second time. The trigger switch 24 operates for the second time to control the resetting of the pneumatic telescopic rod 23 to prepare for the next pushing operation. When the top of the retaining frame 421 rises to the same horizontal plane as the top of the fixed frame 41, the single-drive mechanism 5 stops running, the position of the retaining frame 421 is fixed, and it plays a guiding and limiting role for the angle steel.

[0035] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the single-drive mechanism 5 includes a dual-axis motor 51, a worm 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 part 510, a second worm wheel 511, a second bevel gear 512 and a third bevel gear 513, wherein: The double-axis motor 51 is fixedly connected to the inner wall of the welding part bracket 1, and the worm 52 is symmetrically connected to the inner wall of the welding part bracket 1 and is located on the outside of the double-axis motor 51. One end of the two groups of worms 52 is connected to the output end of the double-axis motor 51 through a one-way transmission device 53 respectively. The first transmission rod 54 and the second transmission rod 55 are connected to the inner wall of the welding part bracket 1 for rotation up and down, and are respectively located on the top side of one group of worms 52 and the bottom side of one group of worms 52. The first transmission rod 54 and the second transmission rod 55 are also connected to the third transmission rod 56 and the fourth transmission rod 57 on one side for rotation. The first bevel gear 58 is respectively arranged at the position corresponding to the position of the first transmission rod 54 and the position corresponding to the first end surface of the third transmission rod 56 and the second transmission rod 55 and the fourth transmission rod 57, and are mutually connected. The first transmission rod 54 and the second transmission rod 55 are meshed with each other. The other end surfaces of the first transmission rod 54 and the second transmission rod 55 are respectively provided with a first worm gear 59, and mesh with the two groups of worm gears 52. The worm portion 510 is uniformly integrally formed and arranged on the surfaces of the first transmission rod 54 and the third transmission rod 56. The second worm gear 511 is uniformly rotated and connected to the inner wall of the welding part bracket 1, and meshes with the worm portion 510. One end of the central axis of the second worm gear 511 is respectively fixedly connected to one end of the central axis of the feeding wheel 31. The second bevel gear 512 is respectively fixedly connected to the surfaces of the second transmission rod 55 and the fourth transmission rod 57, and corresponds to the position of one end of the reciprocating screw 422 penetrating into the interior of the welding part bracket 1. The third bevel gear 513 is fixedly connected to one end surface of the reciprocating screw 422 penetrating into the interior of the welding part bracket 1, and meshes with the second bevel gear 512.

[0036] It should be noted that the dual-axis motor 51 is connected to an external controller via a bus system to achieve data transmission and reception of control instructions.

[0037] It should also be noted that an encoder is fixedly connected to the surface of the dual-axis motor 51, and the encoder is used to detect the number of rotations of the dual-axis motor 51 in real time.

[0038] Specifically, the structure and connection relationship of the single-drive mechanism 5 are further explained. The single-drive mechanism 5 is specially designed to accurately 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, making the operation more convenient. In addition, this design effectively reduces production costs and facilitates subsequent maintenance and repair work.

[0039] During use, the dual-axis motor 51 performs forward or reverse operation according to the received instructions. When the dual-axis motor 51 rotates forward, it only drives the worm 52 matching the position of the first transmission rod 54 to rotate through the one-way transmission device 53. This rotation action drives the first transmission rod 54 to rotate through the synchronization action of the first worm gear 59. Subsequently, the first transmission rod 54 synchronously drives the third transmission rod 56 to rotate through the engagement of the first bevel gear 58. The rotation of the first transmission rod 54 and the third transmission rod 56 synchronously drives the worm portion 510 on their surface to rotate, thereby driving the second worm gear 511 and the loading wheel 31 to rotate, thereby realizing the synchronous loading operation of two groups of angle steels.

[0040] When the dual-axis motor 51 reverses, it only drives the worm 52 matching the position of the second transmission rod 55 to rotate through the one-way transmission device 53. This rotation action also drives the second transmission rod 55 to rotate through the synchronization action of the first worm gear 59. Then, the second transmission rod 55 synchronously drives the fourth transmission rod 57 to rotate through the engagement 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, thereby driving the third bevel gear 513 and the reciprocating screw 422 to rotate, thereby realizing the synchronous lifting operation of the two sets of baffles 421. The lifting and lowering of the baffle 421 synchronously drives the limit guide rod 423, the mounting seat 424 and the cam shaft 425 to lift and lower. During the lifting and lowering process of the cam shaft 425, it will trigger the trigger switch 24 twice in succession. When it is triggered for the first time, the pneumatic telescopic rod 23 is controlled to extend to realize the unloading operation; when it is triggered for the second time, the pneumatic telescopic rod 23 is controlled to reset to prepare for the next pushing operation.

[0041] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the two sets of one-way transmission devices 53 have opposite transmission directions, and both sets of one-way transmission devices 53 are ratchet-type one-way transmission devices.

[0042] Specifically, the transmission direction and type of the one-way transmission device 53 are further limited. By accurately limiting the transmission direction, the one-way transmission device 53 ensures that the dual-axis motor 51 can independently and efficiently drive the loading wheel 31 and the lifting frame 42 to operate 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.

[0043] In one embodiment of the present invention, Figure 1As shown, auxiliary wheels 33 are evenly arranged on the top of the right-angle positioning guide frame 3, and an L-shaped limiting portion 34 is integrally formed on the top of the right-angle positioning guide frame 3 and is located on the inner side of the auxiliary wheel 33. The installation area of ​​the auxiliary wheel 33 is adapted to the two inner side lengths of the right-angle positioning guide frame 3, and the length of the L-shaped limiting portion 34 is smaller than the two inner side lengths of the right-angle positioning guide frame 3. The space between the two groups of L-shaped limiting portions 34 forms a second notch portion 35 for facilitating the horizontal surface welding of the angle steel.

[0044] Specifically, the auxiliary wheels 33 are configured to reduce friction and ensure that the angle steel can be transported smoothly and unimpeded. At the same time, the auxiliary wheels 33 and the L-shaped limit portion 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 portion 35 provides a convenient feed and retract channel for the welding head when performing a 45° welding operation, which not only enhances practicality but also significantly optimizes the use effect.

[0045] In summary, the embodiment of the present invention is an automatic welding device for angle steel tower angle steel. The present invention has a sophisticated structural design and outstanding performance. It can automatically load materials and accurately control the angle steel to move and dock along a preset path, thereby improving processing accuracy and efficiency, ensuring welding quality, and reducing errors. After welding is completed, it can automatically unload materials, further improving work efficiency and reducing manpower burden. At the same time, it avoids human errors and safety hazards, improves product quality and production stability, and has great market promotion and application value.
