Technical Field

[0001] The utility model relates to the technical field of wind power tower manufacturing, and specifically relates to an auxiliary positioning device for flange support installation holes. Background Art

[0002] Wind power generation is an important form of wind energy utilization. A wind turbine is fixed to the ground through a tower barrel. When the wind flows through the blades of the wind turbine, the blades are driven to rotate, converting wind energy into mechanical energy, and then converting the mechanical energy into electrical energy to achieve wind power generation.

[0003] As a tool for preventing deformation during the placement of the tower barrel flange support, it is commonly present in various projects. Currently, flame cutting or punching is used for drilling the flange cross braces. During the processing, there is a situation where the flange hole positions are misaligned, resulting in difficulty in installing the flange cross braces, and rework or scrapping occurs. Moreover, the existing positioning device is inconvenient for positioning the center of the tower barrel flange support, leading to the problem of misaligned flange holes.

[0004] Therefore, a device for positioning the size of the flange support installation hole is designed to conveniently determine the hole position spacing of the flange cross braces, ensure the correct installation hole positions, and reduce rework or scrapping. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Such as Figures 1-4As shown in the figure, the present utility model provides a technical solution: an auxiliary positioning device for flange support mounting holes, including a magnetic suction chuck 1. A fixing block 2 is fixedly connected to the center position at the top of the magnetic suction chuck 1. The bottom of the magnetic suction chuck 1 is composed of magnets. The setting of the magnetic suction chuck 1 facilitates limiting the scale 10 on the surface of the flange support. The top of the magnetic suction chuck 1 is connected to the bottom wall of the fixing block 2 through a connecting shaft. Twelve limiting holes 3 are arranged in an array at the top of the fixing block 2. A support spring 4 is fixedly connected inside the limiting hole 3. A limiting ball 5 is fixedly connected to the top of the support spring 4 inside the limiting hole 3. The top of the limiting hole 3 extends above the axis of the limiting ball 5. A rotating disk 6 is rotatably connected to the center position at the top of the fixing block 2. A rotating hole that meshes with the bottom of the rotating disk 6 is opened at the top of the fixing block 2. The bottom wall of the rotating disk 6 and the top wall of the fixing block 2 form a sliding connection. A limiting groove 7 that meshes with the limiting ball 5 is opened on the bottom wall of the rotating disk 6. The setting of the limiting ball 5 facilitates judging the angle of each rotation when the rotating disk 6 rotates.

[0026] A fixing shaft 8 is fixedly connected to the center position at the top of the rotating disk 6. The top position of the fixing shaft 8 is set to have a smooth surface. The setting of the top of the fixing shaft 8 facilitates moving the magnetic suction chuck 1 away from the workpiece. A clamping plate A9 is fixedly connected to the outer surface at the bottom of the fixing shaft 8. A scale 10 is slidably connected to the outer surface of the fixing shaft 8 above the clamping plate A9. A positioning ring 11 is fixedly connected inside the left end of the scale 10. The axis of the positioning ring 11 coincides with the zero position of the scale 10. The position setting of the positioning ring 11 facilitates positioning the hole position.

[0027] A clamping plate B12 is slidably connected to the outer surface of the fixing shaft 8 above the scale 10. Both the clamping plate A9 and the clamping plate B12 form a sliding connection with the side wall of the scale 10. A wing nut 13 is rotatably connected to the outer surface of the fixing shaft 8 above the clamping plate B12. Indication grooves are opened at the center positions of the front and rear ends of the clamping plate A9 and the clamping plate B12. The setting of the indication grooves facilitates observing the position of the scale 10.

[0028] A threaded groove is opened on the outer surface of the fixing shaft 8 at the position of the wing nut 13. Chute grooves are opened on the front and rear sides of the outer surface of the fixing shaft 8 between the clamping plate A9 and the wing nut 13. Unscrew the wing nut 13 to reduce the friction between the clamping plate B12 and the clamping plate A9. At this time, pull the scale 10 to move to the corresponding dimension. Then tighten the wing nut 13 to limit the scale 10 between the clamping plate B12 and the clamping plate A9. Insert an ink cartridge into the positioning ring 11 to achieve precise positioning. When the limited scale 10 rotates, the scale 10 drives the rotating disk 6 to rotate through the fixing shaft 8. Every time the rotating disk 6 rotates a certain angle, the limiting ball 5 meshes with the limiting groove 7 at the bottom of the rotating disk 6 under the action of the support spring 4, so that the rotation angle can be judged to assist in completing the positioning.

[0029] At the center of the top of the magnetic attraction card holder 1, an adjusting wheel 14 is rotatably connected below the fixed block 2. On both the left and right sides of the top of the magnetic attraction card holder 1, guide rails 15 are fixedly connected. A support plate 16 is slidably connected to the inner wall of the guide rail 15 near the outer surface of the adjusting wheel 14. The guide rail 15 plays a role in guiding and limiting the support plate 16. A toothed plate is provided at one end of the support plate 16 away from the guide rail 15. The support plate 16 meshes with the adjusting wheel 14. One end of the support plate 16 is fixedly connected with a contact block 17. The contact block 17 is coaxially arranged with the magnetic attraction card holder 1. The front end of the adjusting wheel 14 meshes with a connecting wheel 18. The bottom wall of the fixed block 2 is rotatably connected with the connecting wheel 18 by arranging a plug rod. The front end of the connecting wheel 18 meshes with a driving wheel 19. An extension plate rotatably connected with the driving wheel 19 is provided on the front side wall of the fixed block 2. Rotate the driving wheel 19, the driving wheel 19 drives the connecting wheel 18 to rotate, the connecting wheel 18 drives the adjusting wheel 14 to rotate, the adjusting wheel 14 drives the support plates 16 to move towards each other until the support plates 16 drive the contact block 17 to contact the inner wall of the flange support. At this time, the magnetic attraction card holder 1 is located at the center of the flange support, and the magnetic attraction card holder 1 adsorbs on the surface of the flange support.

[0030] Working principle: When the flange support mounting hole auxiliary positioning device is in use, rotate the driving wheel 19. The driving wheel 19 drives the connecting wheel 18 to rotate, the connecting wheel 18 drives the adjusting wheel 14 to rotate, and the adjusting wheel 14 drives the support plates 16 to move towards each other until the support plates 16 drive the contact block 17 to contact the inner wall of the flange support. At this time, the magnetic attraction card holder 1 is located at the center of the flange support, and the magnetic attraction card holder 1 adsorbs on the surface of the flange support. Unscrew the wing nut 13 to reduce the friction between the clamping plate B12 and the clamping plate A9. At this time, pull the scale 10 to move to the corresponding dimension. Then tighten the wing nut 13 to limit the scale 10 between the clamping plate B12 and the clamping plate A9. Insert an ink cartridge into the positioning ring 11 to achieve precise positioning. When the limited scale 10 is rotated, the scale 10 drives the rotating disk 6 to rotate through the fixed shaft 8. Every time the rotating disk 6 rotates a certain angle, the limiting ball 5 meshes with the limiting groove 7 at the bottom of the rotating disk 6 under the action of the supporting spring 4, so that the rotation angle can be judged and the positioning can be assisted to complete.
