During the rotation of the oil receiving pan 11, the inflation component 13 is driven to inflate the inside of the oil pan 11, and the inflation component 13 is used to compress the air and then release it to spray the oil droplets in the oil receiving groove 12 onto the oiling area through the ejected air.

[0036] It is worth noting that the oiling component 8 can move along the X-axis, Y-axis and Z-axis under the drive of the driving member 6, and the driving member 6 also includes a driving component that can drive the oiling component 8 to rotate. Through the sensing component 7, the oiling component 8 can rotate in different directions in space to adapt to oiling locations at different positions in turn.

[0037] As shown in the figure, an oil inlet channel 21 is provided above the oil receiving groove 12 , and an oil injection channel 22 is provided below the oil receiving groove 12 .

[0038] like Figure 7 As shown, a motor 31 for driving the oil receiving pan 11 to rotate is provided on one side of the fuel injection rod 10, a first gear 33 is rotatably provided on the mounting block 32, a belt 34 is sleeved between the first gear 33 and the output shaft of the motor 31, a mounting block 32 is provided on the fuel injection rod 10, a rotating shaft 35 is rotatably provided on the mounting block 32, and a second gear 36 meshing with the first gear 33 is provided on the rotating shaft 35.

[0039] It is worth mentioning again that while the motor 31 drives the oil receiving pan 11 to rotate, the oil in the oil inlet channel 21 is quantitatively transported through the oil receiving groove 12 on the oil receiving pan 11, and the first gear 33 and the second gear 36 are driven to rotate synchronously through the belt 34.

[0040] like Figure 8As shown, the inflation component 13 includes an inflation channel 41 arranged on the injection rod 10 and a piston 42 slidably arranged in the inflation channel 41, the piston 42 is provided with a piston rod 43, the rotating shaft 35 is provided with a turntable 44, the turntable 44 is centrifugally provided with a protrusion 45, the piston rod 43 is provided with a hinge seat 46, the hinge seat 46 is hingedly provided with an articulated rod 47, and one end of the articulated rod 47 is arranged to intersect with the protrusion 45.

[0041] It is worth mentioning again that the first gear 33 drives the second gear 36 to rotate while driving the turntable 44 to rotate through the rotating shaft 35, thereby driving the piston 42 to reciprocate through the rotation of the hinged rod 47, and compressing the air in the inflation channel 41 through the piston 42 to prepare for the subsequent oil spraying. It should be noted that a one-way valve is provided in the inflation channel 41, so that the outside air can only enter the inflation channel 41, and the internal air cannot go out.

[0042] like Figure 3 , Fig.10 As shown, the sensing component 7 includes a sensing plate 51 disposed on the driving member 6 , a photoelectric sensor 52 is disposed on the sensing plate 51 , and a switch sensing sheet 53 is disposed on the photoelectric sensor 52 .

[0043] It is worth mentioning again that the driving member 6 positions the oiling assembly 8 through the photoelectric sensor 52, and the switch sensing piece 53 is used to drive the device to work after positioning.

[0044] like Figure 7 As shown, the oil receiving groove 12 is configured to be an ellipse that expands from the center to the outside.

[0045] It is worth mentioning again that by setting the oil receiving groove 12 to be an ellipse that expands from the center to the outside, when the jet is injected through the jet hole 92, the oil in the oil receiving groove 12 is diffused to both sides, thereby increasing the contact area.

[0046] like Figure 7 As shown, the number of the oil receiving grooves 12 on the oil receiving pan 11 is 3.

[0047] It is worth mentioning again that the number of the oil receiving grooves 12 on the oil receiving pan 11 is set to 3, which increases the time for the jet holes 92 and the air inlet holes 91 to overlap in sequence during rotation, so that the air is more fully compressed and the oiling effect is better.

[0048] like Figure 7 As shown, the oil inlet channel 21 is sized to communicate with the oil receiving groove 12, and the oil injection channel 22 is configured to have a conical shape that gradually widens from the upper right to the lower side.

[0049] It is worth mentioning again that the oil injection channel 22 is provided with a cone that gradually widens from the upper right to the lower right, so that the oil that begins to expand through the oil receiving groove 12 can be expanded again through the oil injection channel 22 so that the oil can be spread evenly on the oiling area.

[0050] like Figure 6 As shown, the gear ratio between the first gear 33 and the second gear 36 is 3:1.

[0051] It is worth mentioning again that by setting the gear ratio between the first gear 33 and the second gear 36 to 3:1 to correspond to the number of oil receiving grooves 12, each oil receiving groove 12 can be aligned with the injection hole 92 to perform air compression and inject the oil so that the oil is sprayed out.

[0052] like Fig. 9 As shown, an air inlet hole 91 is provided on the air charging channel 41 , and an air jet hole 92 is correspondingly provided on the oil receiving groove 12 . The size of the air inlet hole 91 is set to be the same as that of the air jet hole 92 .

[0053] The working process is as follows:

[0054] The worker puts several parts into the drive device in the placement block 4, and the turntable 3 rotates to drive the parts to the bottom of the oiling module 2. The driving member 6 drives the oiling component 8 to move to the oiling place through the induction component 7, and the oil is squeezed into the oil receiving groove 12 from the oil inlet channel 21 through the oil injector 9. The oil receiving plate 11 rotates to drive the oil receiving groove 12;

[0055] The oil receiving pan 11 rotates to drive the oil receiving groove 12 to quantitatively transport the grease. At the same time, the first gear 33 is driven to rotate through the belt 34, and the first gear 33 drives the second gear 36 to rotate. The second gear 36 drives the rotating disk 44 to rotate through the rotating shaft 35. The rotating disk 44 drives the hinge rod 47 through the protrusion 45 to drive the piston 42 to reciprocate.

[0056] When the hinged rod 47 pushes the piston 42, the inflation channel 41 is inflated. When the piston 42 is pulled, external air enters the inflation channel 41 through the one-way valve. When the oil receiving pan 11 rotates, the piston 42 continues to inflate. When the air inlet 91 and the jet hole 92 coincide with each other, the compressed air is ejected to spray out the grease in the oil receiving groove 12, and the grease is broken up and spread on the oiling area through the oil injection channel 22. The above process is repeated until all parts are oiled, and then the workers take out the parts.
