[0026] An axial unit 12 is provided on the left side of the front end of the fixed bracket 111. The axial unit 12 includes a fixed seat 121 fixed to the left side of the front end of the fixed bracket 111. A movable seat 123 is provided on the top of the fixed seat 121.

A drive motor 124 is provided on the top of the movable seat 123. An axial drill bit 125 is provided at the front end of the bottom of the drive motor 124. A sleeve 126 is sleeved on the outside of the axial drill bit 125. Push rods 127 are provided on both sides of the top of the movable seat 123. The front ends of the push rods 127 are respectively connected to the two sides of the sleeve 126.
[0027] A radial unit 13 is provided on the right side of the front end of the fixed bracket 111. The radial unit 13 includes a fixed seat 131 fixed to the right side of the front end of the fixed bracket 111. A movable seat 133 is provided at the front of the fixed seat 131. A hydraulic telescopic rod 132 is provided at the rear end of the movable seat 133. The hydraulic telescopic rod 132 is installed on the fixed seat 131 and is used to push the movable seat 133 to move. A drive motor 134 is provided at the front of the movable seat 133. A radial drill bit 135 is provided on one side of the drive motor 134. A housing 136 is sleeved on the outside of the radial drill bit 135. Push rods 137 are provided at the upper and lower ends of the front of the movable seat 133. The front ends of the push rods 137 are connected to the upper and lower ends of the housing 136, respectively.
[0028] A cutting and grinding unit 14 is provided at the bottom of the fixed bracket 111. The cutting and grinding unit 14 includes a drive motor 141 installed at the bottom of the fixed bracket 111. A cutting disc 142 is provided on the shaft of the drive motor 141. A housing 143 is provided on the top of the cutting disc 142. A connecting pipe 144 is provided on one side of the top of the housing 143. The connecting pipe 144 is connected to the inside of the housing 143. A grinding disc 145 is provided at the middle position of the front end of the cutting disc 142. A housing 2 146 is provided outside the grinding disc 145. The housing 2 146 is fixedly connected to the housing 143. An outer pipe 147 is connected to the top of the housing 2 146.
[0029] Furthermore, the machining mechanism 9 is bolted to the disk 11 of the rotating mechanism 8 and can rotate with the rotating mechanism 8. The machining mechanism 9 is equipped with an axial unit 12, a radial unit 13, and a cutting and grinding unit 14. These units are all mechanisms in which a lead screw and nut pair drives the machining tool to perform linear motion; their differences lie only in the direction of motion.
[0030] The axial drill bit 125 on the axial unit 12 moves parallel to the axis of the rotating mechanism 8, performing machining in the axial direction. Starting the drive motor 124 drives the axial drill bit 125 to rotate. When machining with the axial drill bit 125, the hydraulic telescopic rod 122 pushes the movable seat 123, extending the axial drill bit 125, allowing machining operations to be performed using the rotating axial drill bit 125. During this process, the push rod 127 pushes the sleeve 126 to the end of the axial drill bit 125; the sleeve 126 can, to a certain extent, prevent the axial drill bit 125 from splashing debris during machining. Through the coordinated action of the horizontal X direction, the vertical Y direction, and the rotating mechanism 8, the machining position of the axial unit 12 can be precisely positioned, ensuring the accuracy of the axial hole position.
[0031] The radial unit 13 always moves parallel to the line connecting the pitch circle center of the wind turbine blade and the axis of the rotating mechanism 8. Starting the drive motor 134 drives the radial drill bit 135 to rotate. When machining with the radial drill bit 135, the hydraulic telescopic rod 132 pushes the movable seat 133 to extend the radial drill bit 135, which is then used for machining. The push rod 137 moves the housing 136 to the end of the radial drill bit 135, which helps to prevent debris from flying during machining. Similarly, the combined action of the horizontal (X), vertical (Y), and rotating mechanism 8 ensures the accuracy of the position of the machined radial hole.
[0032] The cutting and grinding unit 14 moves in a circular motion centered on the pitch circle of the wind turbine blade, with the radius of the blade as the radius. Starting the drive motor 141 rotates the cutting disc 142 and the grinding disc 145, thus performing the cutting and grinding process. A dust extraction device is connected to the connecting pipe 144 and the outer pipe 147 to remove dust generated during the cutting and grinding process. This circular motion is achieved through the combined action of the horizontal X direction, the vertical Y direction, and the rotating mechanism 8.
