The grinding driving member 12 is arranged inside the roller grinding sheet 11; the fixing frame 13 is fixed on the clamping seat 113 through a connecting member 114, and isolates the roller grinding sheet 11 and the grinding driving member 12, so that when the grinding driving member 12 drives the driving shaft 111 to drive the roller grinding sheet 11 to rotate, the grinding driving member 12 is limited.

[0025] As a specific embodiment, the grinding driving member 12 is a motor structure.

[0026] That is to say, the motor is arranged inside the fixing frame 13, and the fixing frame 13 is arranged inside the roller grinding sheet 11. The driving shaft 111 of the motor drives the driving shaft 111 to rotate, so that the roller grinding sheet 11 installed on the driving shaft 111 rotates accordingly to achieve grinding. At the same time, the fixing frame 13 and the motor are fixed on the clamping seat 113 through the connecting member 114, so as to limit the motor during grinding, thereby improving the working stability.

[0027] As an embodiment, as shown in Figure 4 the grinding mechanism further includes a swinging member 2. The swinging member 2 is connected to the grinding head 1 through a connecting plate 21, and the swinging member 2 drives the grinding head 1 to swing up and down.

[0029] As a specific embodiment, the swinging driving member 22 is a servo motor, and the buffer member 23 is a cylinder structure.

[0030] That is to say, the grinding mechanism is also provided with a servo motor, which drives the grinding head 1 to swing slightly, so that the roller grinding disc 11 can be adjusted as the curved surface of the fan blade swings; in addition, the grinding head 1 is also provided with a buffer cylinder, through which the roller grinding disc 11 can not only closely adhere to the surface of the fan blade but also not affect the high-speed rotation of the roller grinding disc 11, thus ensuring the grinding quality.

[0031] As an embodiment, the fixed frame 13 is a cuboid, and through holes are provided on the top surface 131 and the bottom surface 132 of the cuboid, so that the fixed frame 13 is clamped on the grinding driving member 12 and the connecting member 114 through the through holes.

[0032] As an embodiment, the side surface of the cuboid is a hollow structure and is provided with integrally formed reinforcing ribs 133.

[0033] That is to say, the fixed frame 13 has an accommodation space for accommodating the motor, and the side surface is set as a hollow structure, and the motor is fixed inside through the integrally formed inclined reinforcing ribs 133, so as to achieve heat dissipation while enhancing the structural strength of the cover body.

[0034] In summary, according to the grinding mechanism proposed by the present invention, it includes a grinding head, and the grinding head includes a roller grinding disc, a grinding driving member and a fixed frame. Among them, one end of the roller grinding disc is connected to the driving shaft, and the other end is connected to the driven shaft; one end of the grinding driving member is connected to the driving shaft through a transmission shaft, and the other end is fixed on the clamping seat through the driven shaft.
