When the grinding machine is used, the servo motor 6 and the circulating pump 9 are started, the servo motor 6 drives the second belt wheel 5 to rotate, the second belt wheel 5 drives the first belt wheel 4 to rotate through a belt, the first belt wheel 4 drives the fixed rotating shaft 3 and the blade 2 to be ground to synchronously start to rotate, when the exhaust material 34 is not in contact with the cutting knife piece 24, the opening of the oil outlet 33 is minimum, the backflow amount is minimum, the hydraulic oil amount conveyed by the circulating pump 9 is gradually increased, and the feeding piston 10 is pushed to gradually feed forward to the cutting knife piece 24 to be in contact with the exhaust material 34;
when the sanding block 13 is fed outwards to the exhaust material 34 to generate pressure on the cutting knife 24, at this time, the cutting knife 24, the arc-shaped sliding block 19, the arc-shaped connecting rod 17 and the first piston 16 respectively slide inwards along the arc-shaped sliding groove 20, the arc-shaped guide groove 18 and the hydraulic oil chamber 15, at this time, the first pressure spring 21 is compressed, hydraulic oil in the hydraulic oil chamber 15 is pushed into the adjusting hydraulic cylinder 28 through the hydraulic oil pipe 14, so that the adjusting piston 29 is pushed to move forwards after the hydraulic oil in the adjusting hydraulic cylinder 28 is increased, the adjusting piston 29 drives the adjusting piston connecting rod 30 to move forwards, so that the adjusting piston connecting rod 30 moves forwards to partially slide into the adjusting sliding groove 32, at this time, the shielding area of the oil outlet 33 by the adjusting plug block 31 is reduced, the oil return amount at the oil outlet 33 is increased, so that the position of the feeding piston connecting rod 11 is kept unchanged at this time, the cutting knife 24 continuously cuts the exhaust material 34, when the exhaust material 34 is not cut by the cutter 24 to be cut after rotating for one circle, the feeding piston 10 feeds forwards for one millimeter to continuously cut the exhaust material 34, along with the continuous forward feeding cutting of the feeding piston 10, when the residual allowance of the exhaust material 34 cannot enable the blade 2 to be ground to rotate for one circle so that the cutting cutter 24 is stressed, the residual allowance of the exhaust material 34 is ground through grinding abrasive paper on the outer end face of the grinding block 13, and due to the deviation of the cutting cutter 24, the finally residual exhaust material is in an inclined shape with a wide front part and a narrow back part, so that the residual exhaust material 34 cannot greatly impact the lower part of the grinding block 13, and can slide to the front end face of the grinding block 13 to be contacted with the grinding abrasive paper more easily, and the residual exhaust material 34 can be ground and removed smoothly;
when the exhaust material 34 presses the cutting knife 24, the cutting knife 24 slides along the arc-shaped sliding block 19 and simultaneously moves under the matching guiding action of the inclined guiding groove 22 and the inclined guiding post 23, the cutting knife 24 shifts to the right along the guiding rod 26 so that the right side arc surface of the cutting knife 24 is aligned with the right side arc surface of the sanding block 13, therefore, the cutting amount of the cutting knife 24 for the first time is the sum of the primary feeding amount of the feeding piston 10 and the transverse distance of the right shift amount of the cutting knife 24 during cutting, namely, 1.5 times of the feeding amount of the feeding piston can be cut for the first time, therefore, after the last time of cutting, the residual amount of the exhaust material 34 is reduced to half of the primary feeding amount of the feeding piston 10, and after the cutting of the cutting knife 24 is finished, the residual amount of the exhaust material 34 is reduced to 0.5 mm, thereby achieving the purpose of reducing the residual amount of the exhaust material 34, the removal amount of the residual amount of the exhaust material 34 by the sand paper layer on the polishing block 13 is reduced, the time required by polishing is shortened, and the polishing efficiency of the fan blade is further improved.
In conclusion, when the fan blade polishing device is used, the exhaust material 34 can be cut by the cutting knife 24, the residual amount to be cut is reduced to the extent that the cutting knife 24 cannot cut the exhaust material 34, the polishing block 13 starts to contact with the exhaust material 34 to polish the exhaust material 34 to remove the residual amount of the material of the exhaust material 34, so that the efficiency of polishing and removing the exhaust material 34 is improved, when the cutting knife 24 of the exhaust material 34 generates pressure on the cutting knife 24, the cutting knife 24 slides along the arc-shaped sliding block 19 and simultaneously moves, under the matching guiding action of the inclined guide groove 22 and the inclined guide post 23, the cutting knife 24 moves along the guide rod 26 in a deviating manner to align the right arc-shaped surface of the cutting knife 24 with the right arc-shaped surface of the polishing block 13, so that the purpose of reducing the residual amount of the exhaust material 34 is achieved, and the residual amount of the abrasive paper layer on the polishing block 13 to the exhaust material 34 is reduced, the time required by polishing is shortened, and the efficiency of polishing the fan blades is further improved.
