[0069] As attached Figure 1 and attached Fig.10 As shown in the figure, the blade polishing method of the grinding equipment for wind turbine blade cutting processing includes the following steps:

[0070] Step 1: The robot arm 1 drives the dust cover 2 to move, and the dust cover 2 is attached to the blade that needs to be polished. The auxiliary wheel 10 assists the movement of the dust cover 2 to ensure stability;

[0071] Step 2: The three-dimensional shape sensor 16 scans the surface of the blade, draws a surface structure diagram of the blade through a computer, and controls the angle adjustment mechanism composed of the first adjustment wheel 23, the first adjustment plate 25, the first hydraulic rod 26, the second adjustment wheel 28, the second adjustment plate 29 and the second hydraulic rod 30;

When the dust brush 12 needs to be removed for cleaning, the handle 14 is pulled outward to separate the handle 14 from the magnetic connection with the magnetic plate 15. The handle 14 drives the first mounting rod 13 fixed thereto to move, so that the first mounting rod 13 is separated from the slot connection with the magnetic plate 15 and the mounting plate 11. Next, remove the dust brush 12 from the dust cover 2, so that the mounting plate 11 fixed above the dust brush 12 is separated from the card slot connection of the dust cover 2, and the dust brush 12 can be cleaned. The cleaned dust brush 12 is placed under the dust cover 2, so that the mounting plate 11 fixed above the dust brush 12 is connected to the card slot of the dust cover 2, and then the first mounting rod 13 is inserted into the dust cover 2, so that the first mounting rod 13 is connected to the card slot of the mounting plate 11, and the handle 14 is magnetically connected to the magnetic plate 15, and the first mounting rod 13 is fixed in the dust cover 2, so as to fix the dust brush 12;

[0077] As attached Figure 6 , Attachment Figure 7 and attached Figure 8As shown in, when the grinding head 17 needs to be disassembled and replaced, the positioning cap 21 is rotated to disengage the positioning cap 21 from the threaded connection with the second mounting rod 20, and then the second mounting rod 20 is rotated to disengage it from the threaded connection with the mounting column 18 and the connecting tube 19, and the mounting column 18 can be taken out from the connecting tube 19, and a new grinding head 17 is placed under the connecting tube 19, so that the mounting column 18 and the connecting tube 19 are connected by the slots, and the second mounting rod 20 is threadedly connected to the mounting column 18 and the connecting tube 19, and the positioning cap 21 is installed at the rear end of the second mounting rod 20, so that the mounting column 18 is fixed in the connecting tube 19, and the grinding head 17 can be fixed.

8. The grinding equipment for cutting and processing wind turbine blades according to claim 7, characterized in that: A second adjusting wheel (28) is fixed above the support frame (24), and the second adjusting wheel (28) is rotatably connected in the dust cover (2), a second adjusting plate (29) is tightly fitted above the second adjusting wheel (28), and a second hydraulic rod (30) is installed on the outer side of the second adjusting plate (29).

9. A blade polishing method using the wind turbine blade cutting and processing grinding device as claimed in claim 1, characterized in that: The blade polishing method of the grinding equipment for cutting and processing wind turbine blades comprises the following steps: step 1: the mechanical arm (1) drives the dust cover (2) to move, and the dust cover (2) is fitted on the blade to be polished, and the auxiliary wheel (10) assists the movement of the dust cover (2) to ensure stability; step 2: the three-dimensional shape sensor (16) scans the surface of the blade, draws a surface structure diagram of the blade through a computer, and controls an angle adjustment mechanism composed of a first adjustment wheel (23), a first adjustment plate (25), a first hydraulic rod (26), a second adjustment wheel (28), a second adjustment plate (29) and a second hydraulic rod (30); step 3: the grinding head (17) is adjusted to fit closely with the surface of the blade, and the drive motor (22) is turned on, and the drive motor (22) drives the grinding head (17) to rotate to grind the blade; step 4: the dust brushes (12) symmetrically distributed at the front and rear are used to block dust generated by grinding to avoid dust generation, and the dust suction pipe (3) is connected to the material pump, and the dust is discharged from the dust suction pipe (3).
