Meanwhile, the first sealing ring 71 and the second sealing ring 82 respectively seal the upper edge and the lower edge of the oil coating hole 101, a closed environment is formed in the oil coating hole 101, and oil is prevented from overflowing from the edge of the oil coating hole 101.
After the oil coating hole 101 of the part 100 is coated, the oil inlet and the air inlet of the gas-liquid two-phase atomizer 64 are closed, the motor 51 stops working, and the output shaft of the total driving oil cylinder 23 retracts to drive the mounting plate 24 to move upwards, so that the oil spraying rod 4 is driven to move upwards until the bottom end of the oil spraying rod 4 rises from the lower edge of the oil coating hole 101 to the upper edge of the oil coating hole 101. Then, the air inlet of the gas-liquid two-phase atomizer 64 is opened, the motor 51 is restarted, the output shaft of the total driving oil cylinder 23 stretches again to drive the mounting plate 24 to move downwards, so as to drive the oil injection rod 4 to move downwards, at the moment, the oil injection hole 43 of the oil injection rod 4 is sprayed into pure gas, the oil injection rod 4 rotates around the axis of the oil injection rod 4 and moves downwards in the oil coating hole 101 of the part 100, the wall of the oil coating hole 101 of the part 100 is blown, and redundant oil attached to the wall of the oil coating hole 101 is blown into the conical groove 91 from top to bottom, so that only one layer of oil film remains on the wall of the oil coating hole 101 to protect the oil film. The oil blown into the tapered groove 91 and the oil dropped into the tapered groove 91 during the oil injection flow into the oil tank 61 through the recovery oil pipe 93 for recovery and utilization.
After the oil coating holes 101 of the part 100 are blown, the air inlet of the gas-liquid two-phase atomizer 64 is closed, the motor 51 stops working, the single-acting air cylinder 32 starts to push the mounting plate 24 to move upwards relative to the connecting plate 31 until the distance between the mounting plate 24 and the connecting plate 31 is fixed, and then the total driving oil cylinder 23 drives the mounting plate 24 to move upwards again, so that the connecting plate 31 and other structures connected to the connecting plate 31 are driven to move upwards until the whole part oiling machine returns to an initial state. At this time, the position of the part 100 is released, and the oil-coated part 100 is removed from the placement base 8 by a manual or mechanical hand.
