As shown in fig. 1, 2, 3 and 4, the embodiment of the invention provides a polishing device for manufacturing aviation parts, which comprises a workbench 1, a polishing mechanism 2, an air extraction cooling mechanism 4, a water supply pipe 6 and a water spray pipe 7, wherein a plurality of rails 11 which are arranged along the transverse direction are arranged on the upper surface of the workbench 1, stations for fixing a skin 100 are reserved between adjacent rails 11, and the length of the rails 11 is longer than that of the skin 100; the polishing mechanism 2 comprises two polishing discs 23, the two polishing discs 23 are used for polishing corresponding side surfaces of the skins 100 adjacent to each other at the same time, the polishing mechanism 2 is arranged on the track 11 in a sliding mode and moves back and forth along the extending direction of the track 11, the water supply pipe 6 is arranged above the skins 100, one ends of the water supply pipes 7 are communicated with the water supply pipe 6, the other ends of the water supply pipes 7 face the upper edges of the two side surfaces of the skins 100, when the polishing mechanism 2 moves to the end portions of the track 11, the air extraction cooling mechanism 4 is used for extracting air from the polishing discs 23, the extracted air is used for preheating water inside the water supply pipes 6, and when the water inside the water supply pipes 6 reaches a preset temperature value, the water supply pipes 7 spray water towards the skins 100.
In this embodiment, by arranging a plurality of rails 11 arranged in the transverse direction on the upper surface of the workbench 1, and reserving a station for fixing the skin 100 between every two adjacent rails 11, the polishing mechanism 2 moves back and forth along the extending direction of the rails 11, and the length of the rails 11 is greater than that of the skin 100, so that two polishing discs 23 of a single polishing mechanism 2 can respectively polish the corresponding sides of two adjacent skins 100 back and forth, thereby improving polishing efficiency; when the polishing mechanism 2 moves to the end of the track 11, the air extraction cooling mechanism 4 can extract air from the polishing disc 23, so that the polishing disc 23 is cooled, the service life of the polishing disc 23 can be prolonged, the processing quality and efficiency are improved, the working environment and the health of operators are protected, meanwhile, the extracted air is used for preheating water in the water supply pipe 6, when the water in the water supply pipe 6 reaches a preset temperature value, the water spray pipe 7 sprays preheated water towards the skin 100, and the air supply pipe is particularly suitable for being used when the air temperature is low, the situation that the water with low temperature is sprayed onto the skin 100 to cause cracking or damage of the skin 100 can be avoided, and the preheated water can effectively absorb and take away heat on the surface of the skin 100, so that the polishing temperature is reduced, dust is reduced, the polishing quality is improved, and the service life of the polishing disc 23 is prolonged.
It should be noted that the lower the water temperature is, the better the cooling effect is, and the reason why the excessively low water temperature may cause the cooling effect to be lowered is as follows:
heat conduction capacity is reduced: the heat conduction capacity of water is weakened along with the reduction of the temperature, when the water temperature is too low, the heat conduction capacity of water is weakened, and the heat on the surface of the skin 100 cannot be effectively absorbed and taken away, so that the temperature of the skin 100 is increased, and the expected cooling effect cannot be achieved;
