[0002] A fan generator generally refers to a wind power generation unit. It is a device that converts wind energy into electrical energy, mainly composed of a fan (also called a wind wheel or a wind blade), a generator, a tower, a control system, etc. When the wind blows the fan, the fan blade is pushed by the wind force to rotate, and the rotating shaft is connected to the generator, and the generator generates electrical energy through the rotating motion. In this way, the kinetic energy of the wind can be converted into electrical energy to realize wind power generation. Wind power generation is a clean energy source with less environmental pollution, and it has received more and more attention and application. When its blades are produced, it is necessary to position the blades to facilitate processing.

Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment: As Figures 1-4 shown, the present invention provides a positioning and detection tooling for the blades of a wind turbine generator, including a base 1. On both sides of the top end of the base 1, fixed plates 2 are fixedly connected. A bidirectional lead screw 3 is rotatably connected between the two fixed plates 2. Symmetrically distributed moving seats 4 are threadedly connected to the outer side of the bidirectional lead screw 3. On one side of the two fixed plates 2 close to the bidirectional lead screw 3, a slide bar 5 is fixedly connected. The moving seats 4 are slidably clamped on the outer side of the slide bar 5. Vertical plates 6 are fixedly connected to the top ends of the moving seats 4. Mounting plates 7 are fixedly connected to the top ends of the vertical plates 6. Two first roller shafts 8 are rotatably connected to the top ends of the mounting plates 7. The mounting plates 7 and the vertical plates 6 are arranged obliquely. In the middle of the top end of the base 1, a hydraulic rod 9 is fixedly installed. The piston rod of the hydraulic rod 9 is fixedly connected to a top plate 10. A second roller shaft 11 is rotatably connected to the top end of the top plate 10. One end of the bidirectional lead screw 3 extends to one side of the fixed plate 2 and is fixedly connected to a turning handle 24.

[0020] On one side of the base 1, there is a bottom plate 13. In the middle of the top end of the bottom plate 13, an electric telescopic rod 14 is fixedly installed. The piston rod of the electric telescopic rod 14 is fixedly connected to a fixed seat 16. A rotating cylinder 18 is rotatably connected inside the fixed seat 16. Symmetrically distributed limit plates 17 are fixedly connected inside the rotating cylinder 18. A toothed ring 19 is fixedly connected to the outer side of the rotating cylinder 18. A stepper motor 20 is fixedly installed on one side of the fixed seat 16 close to the toothed ring 19. The driving end of the stepper motor 20 is fixedly connected to a gear 21. The gear 21 and the toothed ring 19 are meshed and connected.

[0021] By adopting the above technical solution, during use, the telescopic movement of the piston rod of the electric telescopic rod 14 drives the fixed seat 16 to move vertically, facilitating the insertion of the tail end of the blade body 12 between the two limit plates 17 for fixation. The stepping motor 20 drives the gear 21 to rotate. By using the meshing connection between the gear 21 and the toothed ring 19, the rotating cylinder 18 is driven to rotate simultaneously, thereby driving the blade body 12 to rotate, facilitating the machining of the side surface of the blade body 12.

[0022] A blade body 12 is arranged between the base 1 and the bottom plate 13. The connecting end of the blade body 12 is placed between the tops of the first roller shaft 8 and the second roller shaft 11, and the tail end of the blade body 12 is inserted.

[0023] Self-locking wheels 22 are rotatably connected to the four corners at the bottom ends of the base 1 and the bottom plate 13.

[0024] By adopting the above technical solution, by setting the self-locking wheels 22, it is convenient to move and support the component and the rotating component better.

[0025] A second guide rod 23 is arranged between the bottom end of the second roller shaft 11 and the top end of the base 1, and a first guide rod 15 is arranged between the four corners at the bottom end of the fixed seat 16 and the top end of the bottom plate 13.

[0026] By adopting the above technical solution, by setting the second guide rod 23 and the first guide rod 15, it is respectively convenient to guide the vertical movement of the top plate 10 and the fixed seat 16, and at the same time increase the stability of the structure.

[0027] Symmetrically distributed reinforcing ribs 25 are fixedly connected between one side of the vertical plate 6 and the top end of the moving seat 4.

[0028] By adopting the above technical solution, by setting the reinforcing ribs 25, it is convenient to enhance the stability of the structure of the vertical plate 6.

[0029] Working principle: When positioning and detecting the blades of a wind turbine generator, the connecting end of the blade body 12 is placed between the tops of the first roller shaft 8 and the second roller shaft 11. By rotating the rotary handle 24, the bidirectional lead screw 3 is driven to rotate, and at the same time, the two moving seats 4 are driven to move towards the side close to or away from each other, so as to adjust the distance between the first roller shafts 8. Through the telescopic movement of the piston rod of the hydraulic rod 9, the second roller shaft 11 is driven to move vertically to fit the bottom end of the blade body 12, which can be suitable for the support of the connecting ends of blades with different diameters. Then, through the telescopic movement of the piston rod of the electric telescopic rod 14, the fixed seat 16 is driven to move vertically, which is convenient for inserting the tail end of the blade body 12 between the two limiting plates 17 for fixation. The stepping motor 20 drives the gear 21 to rotate. By using the meshing connection between the gear 21 and the toothed ring 19, the rotating cylinder 18 is driven to rotate at the same time, so as to drive the blade body 12 to rotate, which is convenient for processing the side surface of the blade body 12.
