[0039] It should be noted that: under the action of the gravity of the counterweight 41 , the action force between the grinding wheel 47 and the end surface of the wind turbine main shaft body 3 is increased to ensure the grinding effect of the end surface of the wind turbine main shaft body 3 .

[0040] It should be noted that: during the movement of the wind turbine main shaft positioning mold 2, the movement of the wind turbine main shaft positioning mold 2 drives the rectangular bearing seat 420 to move synchronously, and the movement of the rectangular bearing seat 420 drives the hexagonal plug rod 514 to slide inside the connecting column 515. Under the restriction of the hexagonal plug rod 514 and the hexagonal slot 516 structure, the movement of the hexagonal plug rod 514 does not affect the transmission of the hexagonal plug rod 514 and the connecting column 515, so that when the end face of the wind turbine main shaft body 3 is processed, the connecting column 515 is driven to rotate by the hexagonal plug rod 514.

[0041] It should be noted that the first motor 419 can control its main shaft to rotate forward or reverse through the controller.

[0042] It should be noted that: multiple rollers are installed on the bottom surface of the rectangular support seat 420. When the rectangular support seat 420 moves, the multiple rollers roll against the inside of the base 1 to reduce the friction resistance during the movement of the rectangular support seat 420, thereby avoiding the problem of inconvenience in moving the rectangular support seat 420 due to the heavy wind turbine main shaft body 3.

[0043] Working principle: When grinding the rotating end face of the wind turbine main shaft, the wind turbine main shaft body 3 is placed inside the wind turbine main shaft positioning mold 2. Under the action of the shaft groove that matches the appearance of the wind turbine main shaft body 3 opened inside the wind turbine main shaft positioning mold 2, the position of the wind turbine main shaft body 3 is fixed. At this time, the rotating end face of the wind turbine main shaft body 3 and the upper surface of the wind turbine main shaft positioning mold 2 are in contact, so that the grinding motor 44, the electric hydraulic push rod 410 and the first motor 419 are all connected to the external power supply. The operating controller starts the electric hydraulic push rod 410, and the telescopic end of the electric hydraulic push rod 410 during operation begins to retract, so that the first connecting plate 49 moves downward, and then the longitudinal sleeve plate 425 slides downward on the surface of the first built-in slide plate 411;

[0044] During the downward movement of the longitudinal sleeve plate 425, the movement of the longitudinal sleeve plate 425 pulls the wind turbine main shaft positioning mold 2 to move in the direction close to the longitudinal sleeve plate 425 through the second support rod 64, and the wind turbine main shaft positioning mold 2 drives the rectangular bearing seat 420 to slide inside the rectangular slide groove 422 during the movement, thereby ensuring the stability of the wind turbine main shaft positioning mold 2 in the process of driving the wind turbine main shaft body 3 to move, until the wind turbine main shaft positioning mold 2 drives the wind turbine main shaft body 3 to move to the lower position close to the grinding wheel disk 47, so that the grinding wheel disk 47 can be driven to rotate by the operation of the grinding motor 44 to realize the rotating end surface grinding of the wind turbine main shaft body 3. After the end surface grinding of the wind turbine main shaft body 3 is completed, the operation of the electric hydraulic push rod 410 pushes its telescopic end to push the first connecting plate 49 upward The longitudinal sleeve 425 moves upward, and the longitudinal sleeve 425 pushes the wind turbine main shaft positioning mold 2 to move away from the longitudinal sleeve 425 through the second support rod 64 during the movement, so as to facilitate the staff to take out the wind turbine main shaft body 3 from the inside of the wind turbine main shaft positioning mold 2, which is beneficial to the wind turbine main shaft positioning mold 2 to move toward the bottom close to the grinding wheel disc 47 when the end face of the wind turbine main shaft body 3 is ground, so as to facilitate the end face grinding of the wind turbine main shaft body 3 by the rotating grinding wheel disc 47. After the end face grinding of the wind turbine main shaft body 3 is completed, the wind turbine main shaft positioning mold 2 drives the wind turbine main shaft body 3 to move away from the longitudinal sleeve 425, so as to facilitate the staff to operate the wind turbine main shaft body 3 to take it out from the inside of the wind turbine main shaft positioning mold 2;

[0045] When the longitudinal sleeve 425 moves downward, the movement of the longitudinal sleeve 425 causes the longitudinal connecting plate 48 to move toward the direction close to the longitudinal sleeve 425 under the action of the first support rod 53. The movement of the longitudinal connecting plate 48 drives the upper connecting plate 42 and the lower connecting plate 43 to slide synchronously inside the longitudinal sleeve 425, thereby driving the grinding wheel 47 to move synchronously. During this process, the wind turbine main shaft positioning mold 2 moves toward the direction close to the longitudinal sleeve 425, and the grinding wheel 47 moves toward the end face direction close to the wind turbine main shaft body 3. The grinding motor 44 is started. The operation of the grinding motor 44 drives the grinding wheel 47 to rotate through the first rotating shaft 45. As the telescopic end of the electric hydraulic push rod 410 retracts, when When the grinding wheel disc 47 contacts the end face of the wind turbine main shaft body 3, the longitudinal sleeve plate 425 cannot move further at this time, and the telescopic end of the electric hydraulic push rod 410 continues to retract to a suitable position and then stops running. Under the action of the gravity of the counterweight block 41, the grinding wheel disc 47 and the end face of the wind turbine main shaft body 3 have a suitable force, which is conducive to the grinding wheel disc 47 moving towards the end face of the wind turbine main shaft body 3 at the same time through a specific mechanical structure design when the wind turbine main shaft positioning mold 2 moves toward the direction close to the longitudinal sleeve plate 425. Such a design can realize the coordinated action of the wind turbine main shaft positioning mold 2 and the grinding wheel disc 47, greatly improving the convenience of processing the end face of the wind turbine main shaft body 3.

[0046] When grinding the end face of the wind turbine main shaft body 3, the grinding wheel 47 rotates on the end face of the wind turbine main shaft body 3. At this time, the first motor 419 is started. The operation of the first motor 419 drives the second rotating shaft 418 to rotate clockwise. The rotation of the second rotating shaft 418 drives the rotating disk 417 to rotate inside the annular support disk 413, and drives the circular disk 412 and the wind turbine main shaft positioning mold 2 to rotate at the same time. During the rotation of the circular disk 412, the ball 416 rolls inside the lower raceway 415 and the upper raceway 414, thereby reducing the friction resistance during the rotation of the wind turbine main shaft positioning mold 2. During the process of driving the wind turbine main shaft body 3 to rotate, the wind turbine main shaft positioning mold 2 can achieve the effect of grinding the end face of the wind turbine main shaft body 3 through the rotating grinding wheel 47;

[0047] As the second rotating shaft 418 rotates, the third bevel gear 511 is driven to rotate, and the rotation of the third bevel gear 511 drives the hexagonal plug rod 514 to rotate. The rotation of the hexagonal plug rod 514 drives the connecting column 515 to rotate, thereby driving the third rotating shaft 518 and the second bevel gear 59 to rotate synchronously. The rotation of the second bevel gear 59 drives the first bevel gear 57 meshing with it to rotate. The rotation of the first bevel gear 57 drives the threaded rod 56 to rotate. The threaded rod 56 rotates inside the threaded hole 55. Under the action of the thread, when the second built-in slide plate 52 moves upward, the movement of the second built-in slide plate 52 pushes the longitudinal connecting plate 48 to move through the first support rod 53, thereby driving the grinding wheel disc 47 and the grinding motor 44 to move synchronously. As the grinding wheel disc 47 moves, When the end face of the wind turbine main shaft body 3 is ground, the grinding wheel 47 gradually moves toward the center of the end face of the wind turbine main shaft body 3. When the operation of the first motor 419 drives the second rotating shaft 418 to rotate counterclockwise, the second built-in slide plate 52 moves downward. The movement of the second built-in slide plate 52 can pull the longitudinal connecting plate 48 to move away from the longitudinal sleeve plate 425 through the first support rod 53, thereby causing the grinding wheel 47 to move toward the outer circle of the end face of the wind turbine main shaft body 3. This is beneficial for the grinding wheel 47 to fit the end face of the wind turbine main shaft body 3 when the rotating end face of the wind turbine main shaft body 3 is ground, so that the grinding wheel 47 has a spiral grinding path on the end face of the wind turbine main shaft body 3, thereby realizing the grinding of the rotating end face of the wind turbine main shaft body 3.
