When the air pressure stored in the storage tank 18 reaches a certain pressure, the air pressure valve will be opened, so that the air pressure stored in the storage tank 18 enters the inside of the branch pipe 19, and the air pressure in the inside of the branch pipe 19 will be delivered to the inside of the guide groove B26.

[0027] In an optional embodiment, the guide groove B26 is connected with a support 31 outside, one end of the support 31 is connected with the fixed frame 1, a top rod B27 is movably connected inside the guide groove B26, one end of the top rod B27 fixedly connected inside the guide groove B26 is connected with a spring 28, the other end of the spring 28 is connected with the inner wall of the guide groove B26, one end of the top rod B27 outside the guide groove B26 is connected with a flow guide plate 29, after the air pressure enters the inside of the guide groove B26, the top rod B27 will be pushed out, after the top rod B27 is pushed out, the flow guide plate 29 will be pushed to move synchronously, so that the inclined surface of the flow guide plate 29 contacts the air curtain, when the air curtain contacts the inclined surface of the flow guide plate 29, the direction of the air curtain will change so that the airflow blows to the blade being polished, at the same time, when the air pressure enters the inside of the guide groove B26, the wind power of the air curtain will increase synchronously, so that the wind power is transmitted more stably, preventing the airflow from being too small to reflect to the blade, so that the airflow blows off the polishing residues on the surface of the blade during polishing, and the airflow and the cutting fluid cooperate to cool the blade being polished, so that the polishing residues on the surface of the blade are blown off in time, avoiding the accumulation of residues affecting the contact precision of the polishing tool and the blade, ensuring that the blade surface is polished evenly and meets the design requirements, and the airflow and the cutting fluid combination can quickly take away the heat generated by friction during polishing, avoiding the change of metallographic structure or deformation of the blade material due to high temperature, ensuring the mechanical properties of the blade, and further improving the cooling efficiency, speeding up the evaporation and heat absorption of the cutting fluid, and further strengthening the cooling effect. After the air pressure enters the inside of the guide groove B26, the pressure relief port 30 will gradually discharge the air pressure, as the air pressure is discharged, the top rod B27 will be gradually reset by the force of the spring 28, when the top rod B27 is reset, the flow guide plate 29 will be reset synchronously, after the air pressure in the guide groove B26 and the branch pipe 19 is completely discharged, the rack B22 will descend by its own gravity, so that the top rod A23 enters the inside of the guide groove A24, when the rack B22 descends, the gear B20 will be driven to rotate again, so as to open the valve B, so as to reciprocate, when polishing the blade, the airflow is guided to the blade every certain period of time.

[0028] Working principle: when using the device, the blade to be polished is fixed by the clamping seat 2, after the blade is fixed, the push rod 4 is pushed down by the air cylinder 3, when the push rod 4 is lowered, the fixed plate 5 is lowered synchronously, after the fixed plate 5 is lowered, the polishing roller 7 is moved by the two groups of multi-axis mechanical arms 6, so as to polish the blade by the polishing roller 7, at the same time of polishing the blade, the conveying pipe 8 will add certain cutting fluid to the polishing place synchronously, so as to improve the quality and precision of polishing; In the use of the device, the fan will be opened synchronously, and after the fan is opened, the air pressure will be transported into the inside of the two groups of connecting pipes A10. After the air pressure enters the inside of the connecting pipe A10, the valve A is in the initial state of closing, so that after the air pressure enters the inside of the connecting pipe A10, the closing valve A will make the air pressure enter the inside of the connecting pipe B11. After the air pressure enters the inside of the connecting pipe B11, the air pressure will be transported to the spray head 12 through the connecting pipe B11 and sprayed out, and the output end of the spray head 12 is aligned with the two groups of polishing rollers 7 in the initial state, so that after the spray head 12 sprays out the air pressure, the polished polishing rollers 7 will be cooled; When the fixed plate 5 descends, the fixed rod 16 will be descended synchronously. When the fixed rod 16 descends, the rack A15 will be descended synchronously. When the rack A15 descends, the gear A13 will be rotated, and the co-rotating shaft A14 will be rotated synchronously to open the valve A. After the valve A is opened, the air pressure entering the inside of the connecting pipe A10 will enter the inside of the air outlet groove 9, so that the air outlet groove 9 will exhaust the air pressure in the connecting pipe A10, and thus a gas curtain will be formed around the blade to be polished. When the valve A is opened and the connecting pipe A10 transports the air pressure into the inside of the air outlet groove 9, part of the air pressure will enter the storage tank 18 through the connecting pipe C17. When the air pressure stored in the storage tank 18 reaches a certain pressure, the air pressure valve will be opened, so that the air pressure stored in the storage tank 18 enters the branch pipe 19. The air pressure entering the branch pipe 19 will be transported to the guide groove B26. After the air pressure enters the branch pipe 19, part of the air pressure will enter the guide groove A24 through the hose 25. After the air pressure enters the guide groove A24, the top rod A23 will be pushed outwards. After the top rod A23 is pushed outwards, the rack B22 will be pushed upwards synchronously. When the rack B22 is raised, the gear B20 will be driven to rotate. When the gear B20 rotates, the rotating shaft B21 will be rotated to close the valve B in the connecting pipe C17. After the valve B is closed, the connecting pipe C17 will stop the air entering the inside of the storage tank 18, so as to increase the amount of air entering the inside of the air outlet groove 9. After the air pressure enters the guide groove B26, the top rod B27 will be pushed outwards. After the top rod B27 is pushed outwards, the deflector plate 29 will be moved synchronously, so that the inclined surface of the deflector plate 29 contacts the gas curtain. When the gas curtain contacts the inclined surface of the deflector plate 29, the direction of the gas curtain will be changed so that the airflow blows to the polishing blade; After the air pressure enters the inside of the guide groove B26, the pressure relief port 30 will gradually discharge the air pressure, and as the air pressure is discharged, the ejector rod B27 will gradually reset by the force of the spring 28. When the ejector rod B27 resets, it will drive the flow guide plate 29 to reset synchronously. After the air pressure in the guide groove B26 and the branch pipe 19 is completely discharged, the rack B22 will descend by its own gravity, so that the ejector rod A23 enters the inside of the guide groove A24. When the rack B22 descends, it will again drive the gear B20 to rotate, so as to open the valve B, so as to reciprocate in this way. When polishing the blade, the air flow is guided to the blade every certain period of time.
