Description

Technical Field

[0001] This invention relates to the technical field of angle steel tower welding and processing, specifically to a riveting and welding assembly fixture for angle steel tower plates. Background Technology

[0002] Angle steel towers are mostly used in power engineering. To support the installation of cables, angle steel towers are relatively large. During the fabrication of angle steel towers, the tower members are placed on welding fixtures and welded into individual blocks. These blocks are then assembled to form the angle steel tower. The welding fixtures are used to fix the tower members, making it convenient for workers to operate.

[0003] Existing angle steel tower welding fixtures have certain shortcomings in use. Firstly, they are not convenient for fixing angle steel tower members of different volumes, nor are they convenient for welding the included angles of the angle steel tower members. To solve these problems, a welding fixture for angle steel towers disclosed in existing technology (Chinese patent application number CN201921144423.5, application date 2019-07-19) can be referenced. This welding fixture uses a second connecting vertical rod, a telescopic rod, a third connecting vertical rod, and a second limiting rod. The second connecting vertical rod is connected to the third connecting vertical rod via the telescopic rod, facilitating the welding of angle steel tower members. The size of the tower members can be adjusted by the limiting range of the two sets of second limiting rods, which facilitates the fixing of angle steel tower members of different volumes. Alternatively, one can refer to the prior art (Chinese patent application number CN202420813083.5, application date 2024-04-19) which discloses a positioning fixture for welding angle steel towers. This positioning fixture for welding angle steel towers, through the setting of the clamping components, places two steel plates respectively on the clamping grooves on the sides of the left and right rotating plates. Rotating the clamping plates causes them to fit against the sides of the steel plates. Then, twisting the limiting rod causes it to rotate through the bearing, thus adjusting the angle of the limiting rod. The change will cause it to engage with the limiting hole on the side of the clamping plate, so that the clamping plate pressurizes and fixes the steel plate to the side of the clamping groove, thereby achieving a firm clamping of the steel plate and preventing shaking during welding, which would cause welding deformation and affect the overall stability of the angle steel tower. Finally, you can refer to the prior art (Chinese patent application number CN202220735964.0, application date 2022-03-30) which discloses a welding positioning fixture for a double-limb angle steel tower cross plate. This welding positioning fixture is provided by setting a cross groove on the platform and four parts located at the four ends of the cross groove and extending along the ends relative to the cross groove. The extension section extends in the direction of extension, and a sliding seat with a positioning groove is provided on the extension section. When processing the cross plate, the cross groove can first complete the initial positioning of the cross plate to be processed. Then, by sliding and adjusting the sliding seat on the extension section, the positioning groove on the sliding seat can be aligned with the cross plate to be processed, and the positioning is completed. This gives the cross plate a fixed position and angle, and then welding can begin. By setting the table and the base to be rotatably coupled, the table can be rotated after welding is completed on one side without moving, so that welding can continue. This makes the production and processing of cross plates more convenient.

[0004] Although the above-mentioned device can achieve the limited processing of objects, it has certain shortcomings in use. When impact riveting the angle steel tower plate, it is necessary to connect the angle steel tower and the plate. During the impact process, the plate and the angle steel tower will be offset.

[0005] Therefore, we propose a riveting and welding assembly fixture for angle steel tower plates to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a riveting and welding assembly fixture for angle steel tower plates, in order to solve the problem mentioned in the background art that when angle steel tower plates are subjected to impact riveting and welding in the current market, it is necessary to perform butt joint processing on the angle steel tower and the plate, which will cause positional displacement between the plate and the angle steel tower during the impact process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a riveting and welding assembly fixture for angle steel tower plates, comprising a fixing ring, a limiting plate fixed inside the fixing ring, and a feeding component arranged on the left side of the fixing ring; four sets of sliding grooves are formed through the inner side of the limiting plate, and a limiting plate is slidably arranged inside the sliding groove; one side of the limiting plate is connected to a positioning mechanism, and the positioning mechanism drives the limiting plate to move inside the sliding groove to achieve centering positioning of the angle steel tower; the side of the limiting plate is also connected to...

[0010] Preferably, the bottom of the fixed cylinder is fixed to the top side of the limiting plate, and a set of return springs is fixed inside the gas pipe.

The inner side of the buckle plate is provided with an anti-slip pad, and the inner side of the buckle plate is attached to the outer wall of the angle steel tower.

[0011] Preferably, a mating toothed ring is rotatably provided on the inner side of the fixed ring, and a cleaning mechanism is also provided on the inner side of the mating toothed ring. The cleaning mechanism is positioned to clean the welding slag generated at the welding position. A rotating block is fixed on one side of the mating toothed ring, and the outer side of the rotating block is rotatably provided on the inner side of the fixed ring. Several vent holes are also provided on the inner side of the rotating block. The vent holes are rotatably provided in the groove inside the fixed ring, and the groove is connected to the air supply pipe. A vertical pipe is also connected to the inner side of the mating toothed ring. The cooperation between the cleaning mechanism and the shock absorption mechanism realizes the rotation of the mating toothed ring, thereby cleaning the waste slag generated by the impact.

[0012] Preferably, the cleaning mechanism includes a piston rod that slides inside a vertical tube, and the inner side of the vertical tube is connected to the top of the piston rod via a connecting spring. A tapered hole is formed on the inner side of the upper end of the piston rod, and a tapered block is fitted inside the tapered hole. The bottom of the tapered block is connected to the inner side of the piston rod via a cooperating spring. A cleaning block is also fixed at the bottom of the piston rod. A through hole is formed inside the bottom end of the piston rod, and the bottom of the through hole is connected to an air jet hole.

[0013] Preferably, the elastic force of both the connecting spring and the cooperating spring is greater than the elastic force of the return spring, and the piston rod forms an elastic sliding structure between the connecting spring and the interior of the vertical tube.

[0014] Preferably, the outer side of the cleaning block corresponds to the welding position of the angle steel tower, and a brush is provided on the inner side of the cleaning block. In addition, a rubber pad is embedded on the outer surface of the cleaning block.

[0015] Preferably, the shock absorption mechanism includes a delivery pipe connected to one end of a pneumatic component, a rigid pipe connected to the bottom end of the delivery pipe, a groove opened inside the rigid pipe, a piston block slidably disposed inside the delivery pipe, a spiral cylinder fixed to the other end of the piston block, two sets of guide blocks on the outside of the spiral cylinder, the inside of the spiral cylinder being spirally connected to the outside of the spiral rod, and the outer end of the spiral rod being fixed at the center position of the rotating gear.

[0016] Preferably, the spiral cylinder forms a sliding structure with the groove of the rigid tube through the guide block, and the spiral rod and the rigid tube are rotatably connected, with the outer side of the rotating gear meshing with the bottom position of the mating gear ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The impact riveting and welding assembly fixture for angle steel tower plates, through the synergistic action of the positioning mechanism and the side snap-fit ​​mechanism, can center and firmly fix angle steel tower plates of different volumes. At the same time, the cleaning mechanism composed of components such as air supply pipes and vertical pipes, connected by springs and piston rods, removes the welding slag at the welding position after impact riveting by using gas-driven cleaning blocks and air jets. In addition, the plate will vibrate during the impact riveting process. At this time, the vibration damping mechanism can release the potential energy generated by the vibration, thereby driving the meshing gear ring to rotate. This achieves integrated and efficient operation of positioning, fixing, cleaning and vibration damping. The specific details are as follows:

[0018] 1. The positioning mechanism uses a drive motor to rotate a worm gear, which in turn drives the movable rod on the edge of the turntable to move the limiting plate within the slide groove. The four sets of limiting plates can move synchronously relative to each other, achieving the centering positioning of the angle steel tower. This mechanism can adapt to angle steel tower panels of different volumes, solving the problem of traditional tooling being unable to fix components of different volumes. Furthermore, after positioning, the side-mounted locking mechanism uses a gas supply pipe to deliver gas to push the moving gear, which in turn drives the connecting gear to rotate the locking plate, allowing it to rotate from 0 to 90 degrees and fit against the outer wall of the angle steel tower. This, combined with anti-slip pads, achieves secondary fixing, preventing deformation caused by shaking during welding and improving welding accuracy and component strength.

[0019] 2. The cleaning mechanism rotates with the mating gear ring. The gas in the gas supply pipe drives the piston rod to bring the cleaning block into contact with the impact riveting position. At the same time, the gas is ejected from the jet hole through the conical hole and through hole, cleaning the welding slag twice. Furthermore, during the impact riveting process, the plate vibrates on the pneumatic component. The gas pushes the piston block through the delivery pipe. The spiral cylinder and guide block slide through the rigid pipe to achieve the spiral connection. The spiral rod drives the rotating gear to rotate, so that the mating gear ring rotates in the fixed ring, achieving multi-directional cleaning treatment. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 The present invention provides the following technical solution: a riveting and welding assembly fixture for angle steel tower plate components.

[0032] Example 1: To facilitate the positioning of angle steel tower plates, please refer to the attached diagram. Figure 1 - Appendix Figure 3 The system includes a fixed ring 1, with a limiting plate 2 fixed inside the fixed ring 1. A feeding component 27 is located on the left side of the fixed ring 1. Four sets of sliding grooves are formed through the inner side of the limiting plate 2, and a limiting plate 8 is slidably installed inside the sliding groove. One side of the limiting plate 8 is connected to a positioning mechanism. The positioning mechanism drives the limiting plate 8 to move inside the sliding groove, thereby achieving the centering positioning of the diagonal steel tower. The positioning mechanism includes a drive motor 3 fixed to the left side wall of the limiting plate 2. (See attached diagram.) Figure 3Furthermore, the output end of the drive motor 3 is connected to the worm 4 via a coupling. The outer side of the worm 4 is threadedly connected to the worm wheel 5. The center of the worm wheel 5 is fixed at the center of the turntable 6. A movable rod 7 is rotatably mounted on the outer edge of the turntable 6. The other end of the movable rod 7 is rotatably mounted at one end of the limiting plate 8. Four sets of movable rods 7 are arranged at equal angles about the center of the turntable 6. The limiting plate 8 forms a sliding structure with the sliding groove of the limiting plate 2 through the movable rods 7.

[0033] First, the height of the angle steel tower is adjusted using a hydraulic press, and then moved to the position of the angle steel tower. By starting the drive motor 3, the output end of the drive motor 3 can drive the worm gear 4 to rotate. This causes the outer side of the worm gear 4 to drive the meshing worm wheel 5 to rotate around the center of the limiting plate 2. This causes the worm wheel 5 to drive the turntable 6 to rotate on the left side of the limiting plate 2. When the turntable 6 rotates, it drives the movable rod 7 connected to the edge to rotate. This causes the movable rod 7 to drive the limiting plate 8 to move in the sliding groove opened inside the limiting plate 2, so that the four sets of limiting plates 8 can move relative to each other. At this time, the limiting plates 8 can limit the outer side of the angle steel tower. The accessories are placed on the feeding part 27. Since the top of the feeding part 27 is also equipped with a roller, the feeding part 27 will drive the accessories to feed. Then, by opening the valve of the matching conveying pipe 17, the pneumatic component 28 can be used to fit and limit the plate, which is convenient for subsequent impact riveting and welding.

[0034] Example 2: This example differs from Example 1 in that the angle steel tower in Example 1 is further limited in position. See attached diagram for details. Figure 3 - Appendix Figure 5 The side of the limiting plate 2 is also connected to several sets of air supply pipes 9. One end of the air supply pipe 9 is connected to the air supply port of the air pump, and the other end of the air supply pipe 9 extends into the interior of the limiting plate 2 and is connected to the connecting pipe 10. The outer side of the connecting pipe 10 is connected to the side buckling mechanism, which includes a fixed cylinder 11 connected to one side of the connecting pipe 10. (See attached diagram.) Figure 4 The connecting gear 1103 inside the fixed cylinder 11 is fixedly connected to the buckle plate 12, and the rotation angle of the buckle plate 12 is 0 to 90 degrees; see attached drawing. Figure 5 The bottom of the fixed cylinder 11 is fixed to the top side of the limiting plate 8, and a set of return springs 1101 is fixed inside the gas pipe 9. The other end of the return spring 1101 is fixed to the outside of the moving gear 1102. The outside of the moving gear 1102 is meshed with the side of the connecting gear 1103. The inner side of the buckle plate 12 is provided with anti-slip pads, and the inner side of the buckle plate 12 is attached to the outer wall of the angle steel tower.

[0035] Further limiting treatment of the angle steel tower plate is achieved by starting the air pump, which delivers gas to the inside of the air supply pipe 9. The gas inside the air supply pipe 9 is first delivered to the inside of the connecting pipe 10, and then the gas inside the connecting pipe 10 is delivered to the inside of the fixed cylinder 11. At this time, the moving gear 1102 inside the fixed cylinder 11 will move elastically through the return spring 1101. The outer side of the moving gear 1102 will drive the meshing connecting gear 1103 to rotate, and then one side of the connecting gear 1103 will drive the buckle plate 12 to rotate. During the rotation of the buckle plate 12, the angle steel tower is further limited, which facilitates the subsequent impact riveting and welding treatment of the angle steel tower and prevents the angle steel tower from shifting position.

[0036] Example 3: To address the issue of positional misalignment between the angle steel tower and the plate during impact riveting of angle steel tower plates in the current market, where butt welding of the angle steel tower and plate is required, please refer to the attached... Figure 1 Appendix Figure 2 and attached Figure 6 - Appendix Figure 9 The inner side of the fixed ring 1 is rotatably equipped with a mating toothed ring 14, and the position of the cleaning mechanism can clean the welding slag generated at the welding position; see attached figure. Figure 8 The cleaning mechanism includes a piston rod 20 that slides inside a vertical tube 18. The inner side of the vertical tube 18 is connected to the top of the piston rod 20 via a connecting spring 19. A tapered hole 21 is formed on the inner side of the upper end of the piston rod 20. A tapered block 22 is fitted inside the tapered hole 21. The bottom of the tapered block 22 is connected to the inner side of the piston rod 20 via a cooperating spring 23. A through hole 25 is formed inside the bottom end of the piston rod 20. A motor is fixed at the top of the fixing ring 1. A set of rotating gears 13 is fixed at the output end of the machine. The outer side of the rotating gears 13 is meshed with the top of the mating gear ring 14. A rotating block 15 is fixed on one side of the mating gear ring 14, and the outer side of the rotating block 15 is rotatably disposed inside the fixed ring 1. Several vent holes 16 are also provided on the inner side of the rotating block 15. The vent holes 16 are rotatably disposed in the groove inside the fixed ring 1, and the groove is connected to the air supply pipe 9. The inner side of the mating gear ring 14 is also connected to a vertical pipe 18. (See attached diagram.) Figure 9The bottom of the through hole 25 is connected to the jet hole 26; the elastic force of the connecting spring 19 and the cooperating spring 23 are both greater than the elastic force of the return spring 1101, and the piston rod 20 forms an elastic sliding structure between the connecting spring 19 and the interior of the vertical tube 18; the outer side of the cleaning block 24 corresponds to the welding position of the angle steel tower, and a brush is provided on the inner side of the cleaning block 24. In addition, a rubber pad is embedded on the outer surface of the cleaning block 24. The shock absorption mechanism includes a conveying pipe 29 connected to one end of the pneumatic component 28. The bottom end of the conveying pipe 29 is connected to a rigid pipe, and a groove is opened inside the rigid pipe. The piston block 30 is slidably arranged inside the 29. The other end of the piston block 30 is fixed with a spiral cylinder 31. There are two sets of guide blocks 32 on the outside of the spiral cylinder 31. The inside of the spiral cylinder 31 is spirally connected to the outside of the spiral rod 33, and the outer end of the spiral rod 33 is fixed at the center of the rotating gear 13. The spiral cylinder 31 forms a sliding structure with the groove of the hard tube through the guide blocks 32, and the spiral rod 33 is rotatably connected to the hard tube. The outside of the rotating gear 13 is meshed with the bottom position of the mating toothed ring 14. The outside of the piston block 30 is also connected to the inner wall of the hard tube through a spring.

[0037] The cleaning mechanism moves via the gear ring 14. When gas from the gas supply pipe 9 is delivered to the inside of the gear ring 14, the vertical pipe 18 inside the gear ring 14 is inflated. The gas in the vertical pipe 18 drives the piston rod 20, which in turn moves the cleaning block 24. One side of the cleaning block 24 cleans the welded area. When the cleaning block 24 contacts the welded area, it moves via the piston rod 20 and the gear ring 14, cleaning the welded area continuously. This gas then compresses one side of the conical block 22, causing it to move inside the conical hole 21. The conical hole 21 is compressed by the spring 23, allowing gas to pass through the through hole 2. 5. During the jetting process, the gas will clean the riveting position through the jet hole 26, thus cleaning the impact riveting position. During the impact riveting process, the plate will vibrate, which will compress the gas inside the pneumatic component 28 and deliver it to the inside of the delivery pipe 29. Then, the rigid pipe fixed at the bottom of the delivery pipe 29 will be filled with gas, which will cause the piston block 30 to drive the spiral cylinder 31 to move. The spiral cylinder 31 will then move through the guide block 32, which will drive the spiral rod 33 to rotate. The spiral rod 33 will then drive the mating gear ring 14 to rotate through the rotating gear 13. The spring setting facilitates the subsequent reset rotation, thus converting the generated vibration potential energy into rotational potential energy and avoiding positional displacement during multiple impact riveting processes.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
