[0026] Reference Figures 1-6 Figures 1-6 , the positioning and clamping device of the braking disc processing center of the wind turbine provided by the embodiment of the present utility model will be described hereinafter. The positioning and clamping device of the braking disc processing center of the wind turbine includes a base 1, the upper end of the base 1 is fixedly connected with a placing disc 2, a power mechanism 6 is arranged inside the lower end of the base 1, a moving mechanism 3 is arranged inside the upper end of the base 1, the power mechanism 6 is used to provide power for the moving mechanism 3, and a pressing mechanism 4 is arranged inside the moving mechanism 3; fixing ears 7 are fixedly connected to the circumferential surface of the base 1.

[0027] Specifically, when in use, first fix the base 1 inside the processing center through the fixing ears 7, then place the braking disc of the generator to be processed on the placing disc 2, and then the power mechanism 6 works to provide power for the moving mechanism 3. Under the action of the moving mechanism 3, the four pressing mechanisms 4 are driven to move towards the direction of the braking disc of the generator at the same time. In this way, the braking disc of the generator can be positioned under the action of the four pressing mechanisms 4; after positioning, the pressing ends of the pressing mechanisms 4 are pressed on the upper end of the braking disc of the generator at the same time, and then the braking disc of the generator can be fixed with the cooperation of the placing disc 2, thereby facilitating the positioning and clamping of the braking disc of the generator and improving the accuracy of positioning.

[0028] The moving mechanism 3 includes a rotating shaft 301, a disc 302, a fixed shaft 303, a transmission rod 304 and a moving seat 305. The rotating shaft 301 is rotatably connected inside the base 1, the upper end of the rotating shaft 301 penetrates through the placing disc 2 and is rotatably connected with the placing disc 2. A disc 302 is fixedly connected to the circumferential surface of the rotating shaft 301. Four fixed shafts 303 are fixedly connected to the upper end of the disc 302 and are arranged in a circumferential array. The fixed shafts 303 are located at the edge of the disc 302. The transmission rod 304 is rotatably connected to the circumferential surface of the fixed shaft 303, and the end of the transmission rod 304 away from the fixed shaft 303 is rotatably connected with the moving seat 305. When working, the rotating shaft 301 rotates, which drives the moving seat 305 to move under the cooperation of the disc 302, the fixed shaft 303 and the transmission rod 304, thereby driving the four pressing mechanisms 4 to move at the same time, and further facilitating the positioning of the braking disc of the generator.

[0029] A limiting groove 9 is opened at the bottom end inside the base 1, a limiting block 10 is slidably connected inside the limiting groove 9, and a fixed connection is established between the limiting block 10 and the moving seat 305. By providing the limiting groove 9 and the limiting block 10, when working, the movement of the moving seat 305 can be limited under the cooperation of the limiting groove 9 and the limiting block 10, so that the moving seat 305 can move stably.

[0030] The power mechanism 6 includes a second handle 601, a worm 602 and a worm gear 603.

[0031] The pressing mechanism 4 includes a rotating plate 401, a mounting plate 402, a threaded rod 403, a pressing block 404, a rubber pad 405, a first handle 406 and a guide rod 407. The rotating plate 401 is rotatably connected inside the moving seat 305, the upper end of the rotating plate 401 is fixedly connected with the mounting plate 402, the threaded rod 403 is threadedly connected inside the mounting plate 402, the first handle 406 is fixedly connected to the upper end of the threaded rod 403, the lower end of the threaded rod 403 is rotatably connected with the pressing block 404, and the rubber pad 405 is fixedly connected to the lower end of the pressing block 404; the guide rod 407 is slidably connected inside the mounting plate 402, and is fixedly connected between the guide rod 407 and the pressing block 404. During operation, as the moving seat 305 approaches the generator brake disc, when the rotating plate 401 contacts the generator brake disc, the generator brake disc will squeeze the rotating plate 401 to make it rotate. As the rotating plate 401 rotates, it can drive the pressing block 404 to approach the upper end surface of the generator brake disc. When the pressing block 404 contacts the upper end surface of the generator brake disc, the generator brake disc can be clamped and fixed with the cooperation of the placing plate 2. The rubber pad 405 is installed at the lower end of the pressing block 404, and the rubber pad 405 can increase the friction between the pressing block 404 and the generator brake disc, so that the generator brake disc can be stably fixed; when it is necessary to change the position of the pressing block 404, rotate the first handle 406, drive the pressing block 404 to move under the action of the threaded rod 403, thereby driving the guide rod 407 to slide inside the mounting plate 402. Under the action of the guide rod 407, the pressing block 404 can move stably, so that the position of the pressing block 404 can be changed, so that the pressing block 404 can press the generator brake discs with different thicknesses, improving the practicability of the present invention.

[0032] A fixing plate 12 is fixedly connected inside the moving seat 305, a spring 11 is fixedly connected to one side of the fixing plate 12 close to the rotating plate 401, and the end of the spring 11 away from the fixing plate 12 is fixedly connected to the rotating plate 401.
