Description

Technical Field

[0001] This utility model relates to a positioning device for fully automatic riveting of steel pipe towers, belonging to the technical field of positioning devices for riveting of steel pipe towers. Background Technology

[0002] The main component of a steel pipe tower is a steel pipe. Other components are lattice-type towers composed of steel pipes or structural steel. It is a support structure for overhead transmission lines to support conductors and lightning protection wires, ensuring that the conductors meet the distance requirements to the ground and ground objects, and can withstand the loads of the conductors, lightning protection wires, and the tower itself, as well as external loads. During the assembly process, steel pipe towers require rivets to rivet the structure. At this time, positioning devices are needed to position and fix the components before riveting.

[0003] According to CN117548613A, a positioning device for fully automatic riveting of steel pipe towers is proposed. The advantages of this invention are: the automatic feeding and positioning mechanisms on both sides of the processing seat move relative to each other, which can achieve the riveting fit of steel pipe fittings. After the steel pipe fittings are placed on the processing seat, the negative pressure pump creates negative pressure in the negative pressure hole, thereby achieving adsorption and positioning of the steel pipe fittings and ensuring the riveting effect. However, when the above device is in use, the negative pressure hole cannot effectively fix the components. At the same time, when riveting components of different specifications, it cannot accurately position the components, which may result in the rivets not being able to be inserted into the holes of the components, thus affecting the riveting operation. Therefore, the practicality of the device is low. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Example 1 Figures 1-4 This utility model provides a technical solution:

[0023] A positioning device for fully automatic riveting of steel pipe towers includes a base 1. A movable seat 2 is symmetrically slidably mounted on the top of the base 1. Multiple support rods 3 are symmetrically arrayed and slidably embedded on the upper part of adjacent sides of each movable seat 2. A support 4 is fixedly connected to each support rod 3 on one side. A U-shaped seat 5 is slidably mounted on adjacent sides of each support 4. A cylinder 6 is fixedly mounted on the inner wall of the top of each U-shaped seat 5. A pressure block 7 is fixedly connected to the output end of each cylinder 6. A fixed seat 8 is fixedly mounted on the top of the base 1. A hydraulic cylinder 9 is fixedly embedded within the fixed seat 8. A top block 10 is fixedly connected to the output end of the hydraulic cylinder 9. An L-shaped frame 11 is slidably mounted on the top of one side of the base 1. A cylinder 12 is fixedly embedded through the horizontal part of the L-shaped frame 11. A top block 13 is fixedly connected to the output end of the cylinder 12. A magnet 14 is fixedly embedded at the bottom end of the top block 13.

[0024] Specifically, such as Figures 1-4 As shown, a sliding groove 15 is provided at the top front side of the base 1. A dual-head motor 16 is fixedly installed on the inner wall of the middle part of the sliding groove 15. The output ends of the dual-head motor 16 are fixedly connected to screws 17. Slider 18 is threaded on each screw 17. The top of each slider 18 is fixedly connected to the bottom of the adjacent movable seat 2. The slider 18 is slidably connected to the sliding groove 15. The two screws 17 are provided with threads in opposite directions. The dual-head motor 16 drives the screws 17 to rotate, so that the screws 17 drive the sliders 18 to move towards each other in the sliding groove 15. The sliders 18 can drive the movable seat 2 to move towards each other.

[0025] Specifically, such as Figures 1-4As shown, each of the upper parts of the movable seat 2 is provided with a sliding groove 19. A rotating motor 20 is fixedly installed on one inner wall of each sliding groove 19. The output end of each rotating motor 20 is fixedly connected to a screw 21. A slider 22 is threaded onto each screw 21. The end of the support rod 3 away from the support 4 extends into the adjacent sliding groove 19 and is fixedly connected to the slider 22. The rotating motor 20 drives the screw 21 to rotate, which in turn drives the slider 22 to move. This causes the slider 22 to move the support 4 via the support rod 3, thereby adjusting the support 4 to a suitable position.

[0026] Specifically, such as Figures 1-4 As shown, each of the supports 4 has a sliding groove 23 on the side near the U-shaped seat 5. A rotating motor 24 is fixedly installed on the inner wall of the top of each sliding groove 23. A screw 25 is fixedly connected to the output end of each rotating motor 24. A slider 26 is threaded onto each screw 25. The slider 26 is fixedly connected to the side of the U-shaped seat 5 adjacent to it. The rotating motor 24 drives the screw 25 to rotate, which causes the screw 25 to move the slider 26 within the sliding groove 23. The slider 26 can move the U-shaped seat 5 up and down, thereby adjusting the U-shaped seat 5 to a suitable height.

[0027] Specifically, such as Figures 1-4 As shown, the base 1 has a sliding groove 27 at the top of the side near the vertical part of the L-shaped frame 11. A rotating motor 28 is fixedly installed on the inner rear wall of the sliding groove 27. A screw 29 is fixedly connected to the output end of the rotating motor 28. A slider 30 is threaded on the screw 29. The top end of the slider 30 is fixedly connected to the bottom end of the L-shaped frame 11. The rotating motor 28 drives the screw 29 to rotate, which in turn drives the slider 30 to move. The slider 30 can then drive the L-shaped frame 11 to move back and forth.

[0028] Please refer to Example 2 Figures 1-4 The difference between this embodiment and embodiment 1 is that the outer wall of the support rod 3 is provided with scale lines. By setting scale lines, it is easy to know the distance between the support 4 and the movable seat 2.

[0029] The working principle of this utility model is as follows: During use, the device is adjusted according to the specifications of the components. At this time, rotating motor 20 drives screw 21 to rotate, causing screw 21 to move slider 22. Slider 22 then moves support 4 via support rod 3, allowing support 4 to be adjusted to a suitable position. A scale is provided to easily determine the distance between support 4 and moving seat 2. Then, rotating motor 24 drives screw 3 25 to rotate, causing slider 3 26 to move within groove 3 23. Slider 3 26 moves U-shaped seat 5 up and down, allowing adjustment to a suitable height. A robotic arm places one end of each of the two components into the corresponding U-shaped seat 5. Finally, cylinder 6 pushes pressure block 7 downwards, fixing the components in the U-shaped seat 5. Inside seat 5, the double-headed motor 16 drives the screw 17 to rotate, causing the screw 17 to drive the slider 18 to move towards each other in the groove 15. The slider 18 can drive the moving seat 2 to move towards each other, so that the holes of the two components overlap and ensure that the holes are directly above the top block 10. The cylinder 2 pushes the top block 2 13 downward, so that the rivet can be attracted by the magnet 14. The rotating motor 3 28 drives the screw 4 29 to rotate, so that the screw 4 29 drives the slider 4 30 to move. The slider 4 30 can drive the L-shaped frame 11 to move forward, so that the rivet is moved to the appropriate position. The cylinder 2 pushes the top block 2 13 downward, so that the rivet can be inserted into the hole. Then, the hydraulic cylinder 9 pushes the top block 10 upward and squeezes the bottom end of the rivet, thus completing the riveting of the components.
