The bottom plate 84 is further fixedly connected with a plurality of positioning columns 83 through screws, and the positioning columns 83 are arranged along the axial direction of the plugging column 81. The inside of the frame 1 is also provided with a recovery assembly 9 as shown in fig. 6, the recovery assembly 9 comprises a tapered groove 91 formed at the top of the plugging column 81, and the size of the upper opening of the tapered groove 91 is matched with the size of an oiling hole 101 of the part 100. The blocking column 81 is further provided with a recovery oil hole 92 along the axis thereof, the upper end of the recovery oil hole 92 is communicated with the bottom of the tapered groove 91, and the lower end of the recovery oil hole 92 is connected with a recovery oil pipe 93. Through holes penetrating through the upper surface and the lower surface of the base plate 84 and the frame 1 are formed in the base plate 84 and the frame 1, and the other end of the recovery oil pipe 93, which is opposite to the end connected with the recovery oil hole 92, sequentially penetrates through the through hole of the base plate 84 and the through hole of the frame 1 to be connected with an oil inlet of the oil drum 61.

When the part oiling machine is used, the parts 100 are firstly placed on the placing seat 8 manually or by a mechanical arm, positioning holes 103 of the parts 100 in fig. 1 are aligned with positioning columns 83 in fig. 5 one by one during placing, so that the parts 100 are accurately placed, at the moment, the blocking columns 81 support the oiling holes 101 of the parts 100, and the second sealing rings 82 are in contact with the parts 100 to seal the lower edges of the oiling holes 101 of the parts 100. Then the main driving oil cylinder 23 is started, the main driving oil cylinder 23 pushes the mounting plate 24 to move downwards along the upright post 21, at the moment, the single-acting air cylinder 32 is in a starting state, the single-acting air cylinder 32 abuts against the mounting plate 24, so that the mounting plate 24 and the connecting plate 31 do not generate relative displacement, the connecting plate 31 also moves towards a direction close to the part 100 under the pushing of the main driving oil cylinder 23 until the pressing seat 7 and the plurality of pressing rods 72 contact with the part 100 and press the part 100 against the blocking post 81 and the positioning post 83, at the moment, the first sealing ring 71 contacts with the part 100 to seal the upper edge of the oil coating hole 101 of the part 100, and the second sealing ring 82 contacts with the part 100 to seal the lower edge of the oil coating hole 101 of the part 100, so that a 'sealed' space is formed in the oil coating hole 101 of the part 100. During the downward movement of the connecting plate 31, the tube-type cylinder 74 fixedly connected to the lower surface of the connecting plate 31 also moves downward, when the pressing base 7 and the pressing rod 72 press the part 100 tightly, the output shaft of the tube-type cylinder 74 aligns with the side hole 102 of the part 100, and then the tube-type cylinder 74 is started to drive the plug 73 to move towards the direction close to the side hole 102 of the part 100 until the plug 73 blocks the side hole 102 of the part 100.

After the position of the part 100 is fixed, the main driving mechanism 2 continues to drive the mounting plate 24 to move downwards along the upright post 21, at this time, the single-acting cylinder 32 loses the supporting force on the mounting plate 24 and is pushed by the main driving cylinder 23 to extrude the mounting plate 24, the piston rod of the single-acting cylinder 32 contracts downwards, the mounting plate 24 slides downwards on the guide posts 33, the oil injection rod 4 and the rotating device 5 also continue to move downwards along with the mounting plate 24, the bottom end of the oil injection rod 4 penetrates through the working hole 76 of the pressing seat 7 to enter the oil coating hole 101 of the part 100 and continues to move downwards in the oil coating hole 101 until reaching the top of the tapered groove 91. In the process that the bottom end of the oil spraying rod 4 moves downwards in the oiling hole 101 of the part 100, an oil inlet and an air inlet of the gas-liquid two-phase atomizer 64 are simultaneously opened, the gas-liquid two-phase atomizer 64 conveys atomized oil into the oil duct 42 of the oil spraying rod 4 through the oil outlet pipe 65, and the atomized oil is sprayed on the hole wall of the oiling hole 101 through the oil spraying hole 43 formed in the side wall of the bottom end of the oil spraying rod 4; the throttle valve 63 controls the amount of oil in the above process; the motor 51 of the rotating device 5 is started, the motor 51 drives the driving wheel 52 to rotate, and the driving wheel 52 drives the driven wheel 54 to rotate through the belt 53 so as to drive the oil spray rod 4 to rotate around the axis of the oil spray rod. In the process that the bottom end of the oil spraying rod 4 moves from the upper edge of the oil coating hole 101 of the part 100 to the lower edge of the oil coating hole 101, the oil spraying rod 4 rotates around the axis of the oil spraying rod all the time, and the uniformity of oil coating on the hole wall of the oil coating hole 101 of the part 100 is improved.

In the process of oiling the oil coating hole 101 of the part 100, the plug 73 blocks the side hole 102 communicated with the oil coating hole 101, so that the oil sprayed from the oil spraying hole 43 of the oil spraying rod 4 is prevented from being sprayed to the outer surface of the part 100 through the side hole 102 to influence the appearance of the part 100. Meanwhile, the first sealing ring 71 and the second sealing ring 82 respectively seal the upper edge and the lower edge of the oiling hole 101, so that a closed environment is formed in the oiling hole 101, and oil is prevented from overflowing from the edge of the oiling hole 101.

After the oiling hole 101 of the part 100 is oiled, the oil inlet and the air inlet of the gas-liquid two-phase atomizer 64 are both closed, the motor 51 stops working, the output shaft of the main driving oil cylinder 23 retracts to drive the mounting plate 24 to move upwards, so that the oil spray rod 4 is driven to move upwards until the bottom end of the oil spray rod 4 rises from the lower edge of the oiling hole 101 to the upper edge of the oiling 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 main driving oil cylinder 23 extends again to drive the mounting plate 24 to move downwards, so that the oil spray rod 4 is driven to move downwards, pure gas is sprayed out from the oil spray hole 43 of the oil spray rod 4 at the moment, the oil spray rod 4 rotates around the axis of the oil spray rod 4 to move downwards in the oil coating hole 101 of the part 100, the hole wall of the oil coating hole 101 of the part 100 is blown, redundant oil attached to the hole wall of the oil coating hole 101 is blown off from top to bottom and enters the conical groove 91, and only one layer of oil film is left on the hole wall of the oil coating hole 101 to protect the oil coating hole. The oil blown into the tapered groove 91 and the oil dropped into the tapered groove 91 in the oil injection process flow into the oil drum 61 through the recovery oil pipe 93, and are recovered and utilized.

After the air blowing is finished on the oil coating holes 101 of the parts 100, the air inlet of the gas-liquid two-phase atomizer 64 is closed, the motor 51 stops working, the single-acting air cylinder 32 is started 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 main driving oil cylinder 23 drives the mounting plate 24 to continue moving 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 the initial state. At this time, the position fixing of the parts 100 is released, and the parts 100 after the oil application are taken out from the placing base 8 by a worker or a robot.
