[0025] refer to Figure 1-2 A U-shaped handle 3 is fixedly provided on the upper surface of the protective frame 1, a connecting frame 13 is fixedly provided inside the protective frame 1, bearings 12 are symmetrically fixedly provided at the upper and lower ends of the connecting frame 13, the output shaft of the driving motor 41 is fixed to the inner ring of the bearing 12, a bracket 14 is fixedly provided on the outer surface of the lower end of the connecting frame 13, and the bracket 14 is fixed to the inner wall of the protective frame 1.

[0026] refer to Figure 2The connection frame 13 can be used to protect the output shaft of the driving motor 41 and prevent debris from adhering to the surface of the output shaft of the driving motor 41 and affecting its rotation.

[0027] refer to Figure 3-8 A plurality of sector-shaped oil storage chambers 58 are provided in a ring shape in the grinding frame 5. A cover plate 57 is fixedly provided at the outer end of the oil storage chamber 58. The cover plate 57 is used to seal the oil storage chamber 58, and an oil delivery hole 571 is provided on the surface of the cover plate 57. The oil storage chamber 58 is filled with oil through the oil delivery hole 571, and then the oil delivery hole 571 is closed by bolts.

[0028] refer to Figure 3-8 A plurality of grooves 51 are linearly provided on the surface of the grinding frame 5 between every two adjacent oil storage chambers 58, a spring 3 55 is fixedly provided in the groove 2 51, a sliding plate 54 is fixedly provided at the outer end of the spring 3 55, the sliding plate 54 is slidably provided in the groove 2 51, a baffle 52 is fixedly provided at the outer end of the groove 2 51, and the baffle 52 can further prevent the oil in the oil storage chamber 58 from flowing out.

[0029] refer to Figure 5 A grinding column 53 is fixedly provided on the outer surface of the sliding plate 54, and the grinding column 53 penetrates the baffle 52 and is slidably fitted.

[0030] refer to Figure 5 Oil drain holes 56 are symmetrically provided on both sides of the groove 2 51 , and the oil drain holes 56 are communicated with the oil storage chamber 58 . The oil drain holes 56 are located on the inner side of the sliding plate 54 , and when the spring 3 55 is at the compression limit, the groove 2 51 can still be communicated with the oil storage chamber 58 .

[0031] Furthermore, after the protective frame 1 is brought close to the surface of the rotor blade, since the blade is an irregular spiral surface, it is difficult to grind its surface with an ordinary flat grinding wheel. The grinding frame 5 will gradually approach the blade surface along with the protective frame 1. Due to the irregularity of the blade surface, the length of the groove 2 51 exceeded by each grinding column 53 will be different, and then the grinding frame 5 is rotated by driving the motor 41.

[0032] As the grinding area of ​​the blade increases, the protective frame 1 will gradually move, and at the same time the grinding column 53 will press the sliding plate 54, and then the sliding plate 54 will slide in the groove 2 51, at this time the sliding plate 54 will squeeze the spring 3 55 and the oil, the oil returns to the oil storage chamber 58, and the spring 3 55 is compressed. In this process, since the oil has a certain density, the grinding column 53 will be slowly squeezed and contracted, which will not affect the grinding effect of the grinding column 53 and the blade during rotation, so that the grinding column 53 is always in contact with the surface of the blade, thereby improving the grinding effect of the blade surface.

[0033] Embodiment 2:

[0034] refer to Figure 2-4 On the basis of the first embodiment, in order to further collect the grinding debris, a through hole 11 can be opened on the upper surface of the protective frame 1, and the through hole 11 is used to connect an air pump to collect the grinding debris through the air pump.

[0035] refer to Figure 2-4 A ring groove 15 is provided on the lower end surface of the protective frame 1, and a plurality of springs 62 are fixedly arranged in a ring shape in the ring groove 15. An arc-shaped slider 6 is fixedly arranged on the outer end of the spring 62. The slider 6 is slidably arranged in the ring groove 15, and a brush 61 is fixedly arranged on the lower surface of the slider 6. A protective ring can be formed by a plurality of arc-shaped sliders 6 to prevent grinding debris from splashing to the outside.

[0036] Furthermore, due to the irregular shape of the blade surface, after the protective frame 1 is placed on the blade surface, the plurality of sliders 6 will automatically shrink into the annular groove 15 according to the shape of the blade surface. At this time, the brush 61 will not be squeezed too severely, and a better protective effect can be achieved.

[0037] Embodiment three;

[0038] refer to Figure 2-6 On the basis of the first embodiment, in order to further reduce the force consumed when moving the protection frame 1 , a plurality of L-shaped support rods 2 may be fixedly provided in a ring shape on the side of the protection frame 1 .

[0040] Furthermore, after the protective frame 1 is brought close to the blade surface, the spherical magnet will be directly adsorbed on the blade surface. At this time, due to the irregular shape of the blade surface, the height of each spherical magnet will be different. When moving the protective frame 1 subsequently, you only need to push it, and you don't have to always hold the U-shaped handle 3 to control the height of the protective frame 1. When grinding, press the protective frame 1. At this time, the spherical magnet will push the support plate 1 22 to squeeze the spring 2 23, so that the grinding column 53 contacts the blade surface.
