[0038] The driving motor 24 is started, and the driving motor 24 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the two transmission chains 23 to move synchronously through the sprocket 21.

[0040] The bearing is hung on the cross bar 33, and the limit block 35 moves upward under the elastic force of the limit spring 38. The bearing is located between the limit block 35 and the vertical rod 32. The vertical rod 32 and the limit block 35 limit the bearing, making it difficult for the bearing to separate from the cross bar 33.

[0041] Reference Figure 1 and Figure 2A supporting plate 14 is installed above the fixed plate 11. Vertical supporting rods 15 are fixed to the corners of the bottom surface of the supporting plate 14. The bottom ends of the supporting rods 15 are fixedly connected to the top surface of the fixed plate 11. A pump 16 is installed on the top surface of the supporting plate 14. An upward-opening oil tank 4 is installed below the fixed plate 11. A filter 41 is installed in the oil tank 4. An oil inlet pipe 42 is installed at the bottom of the oil tank 4. The end of the oil inlet pipe 42 away from the oil tank 4 is connected to the oil inlet end of the pump 16. An oil outlet pipe 43 is fixed to the oil outlet end of the pump 16.

[0042] Reference Figure 1 and Figure 3 A placement rack 5 for placing bearings is fixed to the top surface of the fixed plate 11, and the placement rack 5 is located on the side of the horizontal rod 33 away from the vertical rod 32. The placement rack 5 includes a vertically arranged rotating cylinder 51, and the rotating cylinder 51 is rotatably connected to the fixed plate 11. A plurality of spaced placement rods 52 are fixed to the outer circumference of the rotating cylinder 51, and the placement rods 52 include a hanging rod 522 and a horizontally arranged connecting rod 521. One end of the hanging rod 522 is fixedly connected to the connecting rod 521, and the other end of the hanging rod 522 is fixedly connected to the outer circumference of the rotating cylinder 51, and the hanging rod 522 is tilted upward near one end of the connecting rod 521. A positioning ring 53 is fixed on the outer circumference of the rotating cylinder 51, and a plurality of spaced positioning through holes 54 are provided on the top surface of the positioning ring 53. A mounting hole 55 is formed on the top surface of the fixing plate 11 , and a pin 56 is passed through the positioning through hole 54 . The bottom end of the pin 56 can be inserted into the mounting hole 55 , thereby fixing the rotating cylinder 51 .

[0043] Reference Figure 1 and Figure 3 The top surface of the fixed plate 11 is fixed with a mounting support 6, and the top of the mounting support 6 is fixed with an electric cylinder 61. The electric cylinder 61 is located on the side of the movable frame 3 away from the placement frame 5. The end of the piston rod of the electric cylinder 61 is fixed with a connecting plate 62. The side of the connecting plate 62 near the placement frame 5 is fixed with two push blocks 63, which can abut against the bearings.

[0044] When the movable rack 3 moves to between the electric cylinder 61 and the placement rack 5, the cross bar 33 touches one of the connecting rods 521, and the piston rod of the electric cylinder 61 drives the pushing block 63 to move toward the direction close to the bearing. The pushing block 63 pushes the bearing onto the connecting rod 521, and then pushes the bearing onto the hanging rod 522. The bearing moves toward the direction close to the rotating cylinder 51 under the action of its own gravity, thereby transferring the oiled bearing to the placement rack 5.

[0045] Reference Figure 1 and Figure 4 A control block 7 is fixed to the top surface of the fixed plate 11, and the control block 7 is located below the electric cylinder 61. A control groove 71 is provided on the side of the control block 7 away from the nozzle 45, and the control block 7 is slidably installed with a trigger block 72 along the length direction of the fixed plate 11 through the control groove 71. A trigger spring 73 is fixed to the side of the trigger block 72 close to the nozzle 45, and one end of the trigger spring 73 away from the trigger block 72 is fixedly connected to the inner wall of the control groove 71. A moving contact piece 74 is fixed to the top surface of the trigger block 72, and a clearance groove 75 is provided on the inner wall of the control groove 71. The moving contact piece 74 is slidably connected to the control block 7 along the length direction of the fixed plate 11 through the clearance groove 75. A fixed contact piece 76 is fixed to the inner wall of the clearance groove 75 close to the nozzle 45, and the fixed contact piece 76 can be in electrical contact with the moving contact piece 74. The fixed contact piece 76 is electrically connected to the power supply, and the movable contact piece 74 is electrically connected to the electric cylinder 61. When the movable contact piece 74 is electrically in contact with the fixed contact piece 76, the electric cylinder 61 is energized and operates.

[0046] Reference Figure 1 and Figure 4 Two mounting blocks 81 are fixed to the side of the control block 7 away from the nozzle 45. A push rod 82 is rotatably mounted between the two mounting blocks 81. The outer circumference of the push rod 82 is sheathed with a push plate 8. A torsion spring 83 is sheathed on the outer circumference of the push rod 82. One end of the torsion spring 83 is fixedly connected to the push plate 8, and the other end of the torsion spring 83 is fixedly connected to the mounting block 81. Under the elastic force of the torsion spring 83, the push plate 8 abuts against the control block 7. The push plate 8 can abut against the trigger block 72, thereby separating the movable contact piece 74 from the fixed contact piece 76. The vertical rod 32 abuts against the push plate 8 and drives the push plate 8 away from the control block 7. This causes the trigger block 72 to move toward the push plate 8 under the elastic force of the trigger spring 73. The movable contact piece 74 makes electrical contact with the fixed contact piece 76, energizing the electric cylinder 61 and pushing the bearing onto the placement rack 5.

[0047] The implementation principle of the bearing oiling device of the embodiment of the present application is as follows: the bearing is hung on the cross bar 33, and the limit block 35 limits the bearing so that the bearing is not easily separated from the cross bar 33; the drive motor 24 is started, and the drive motor 24 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the two transmission chains 23 to move synchronously through the sprocket 21, and the transmission chain 23 drives the movable frame 3 to move. When the bearing on the movable frame 3 moves to the middle of the two spray heads 45, the spray heads 45 evenly spray oil on both sides of the bearing. The bearing after the oil spraying continues to move toward the placement frame 5;

[0048] When the bearing moves to a position close to the placement rack 5, the vertical rod 32 contacts the push plate 8 and pushes the push plate 8 to move away from the control block 7. The trigger block 72 moves toward the push plate 8 under the elastic force of the trigger spring 73, so that the movable contact piece 74 is in electrical contact with the fixed contact piece 76. The electric cylinder 61 is energized and the piston rod of the electric cylinder 61 drives the push block 63 to move. The push block 63 pushes the bearing on the cross bar 33 onto the connecting rod 521, thereby realizing the transportation of the bearing.

[0049] When the electric cylinder 61 drives the push plate 8 to reset, the vertical rod 32 separates from the push plate 8, and the push plate 8 moves toward the direction close to the control block 7 under the elastic force of the torsion spring 83. The push plate 8 abuts against the trigger block 72 and drives the trigger block 72 to move, so that the moving contact piece 74 is separated from the fixed contact piece 76, and the electric cylinder 61 stops working.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
