[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example: Reference Figure 1-3 The lubricating oil wiping equipment for bearing seat production shown includes a wiping unit. The wiping unit is installed on the base 1 and can automatically wipe the inner and outer surfaces of the bearing seat 6.

[0019] As a preferred embodiment of this embodiment, the wiping unit includes a drive cylinder 3 mounted on a mounting plate 2, a protective cover 4 fixedly connected to the output end of the drive cylinder 3 via a connecting rod, and a groove plate 7 provided with a groove and located directly below the protective cover 4; The mounting plate 2 and the groove plate 7 are both arranged on the base 1; The upper end of the protective cover 4 is equipped with an upper motor 5, and the output shaft of the upper motor 5 passes through the protective cover 4 and is fixedly connected to the upper support net 16. The upper support net 16 is adapted to the upper surface of the bearing seat 6. A lower support net 20 adapted to the inner surface of the bearing seat 6 is provided in the groove of the groove plate 7, and an oil absorption layer 18 is provided on the outer surface of the lower support net 20 and the inner surface of the upper support net 16; A lower motor 26 is mounted on the base 1 , and an output shaft of the lower motor 26 passes through the groove plate 7 and is fixedly connected to the lower support net 20 .

[0020] In actual use, after the bearing seat 6 is manually placed on the lower support net 20 (at this time the oil-absorbing layer 18 located below is in contact with the inner cavity surface of the bearing seat 6), the start button of the controller is manually pressed to drive the cylinder 2 to drive the protective cover 4 to move downward, and finally make the oil-absorbing layer 18 set above conflict with the upper surface of the bearing seat 6. At this time, the upper motor 5 and the lower motor 26 are working, respectively driving the upper oil-absorbing layer 18 to rotate clockwise at a low speed, and driving the lower oil-absorbing layer 18 to rotate counterclockwise at a low speed. The upper and lower oil-absorbing layers 18 rotate in opposite directions, and some friction forces offset each other, which is conducive to maintaining the stability of the bearing seat 6. After the low-speed rotation is completed, each motor stops working, and the drive cylinder 2 drives the protective cover 4 to return to its original position. At this time, the operator can remove the bearing seat 6 that has been wiped. The automated operation of this equipment replaces manual wiping, significantly reducing labor intensity and improving efficiency several times compared to manual operation.

[0021] It should be noted that: 1. The upper motor 5, the lower motor 26 and the drive cylinder 2 are all electrically connected to the controller; 2. The oil absorption layer 18 can be made of graphene-based polyurethane oil absorption sponge or polyester fiber material, which has a good oil absorption effect and is also conducive to the subsequent separation of the lubricating oil from the oil absorption layer 18 through suction; 3. A plurality of tiny through holes can also be densely arranged on the oil absorption layer 18 to increase the contact area between the oil absorption layer 18 and the lubricating oil. At the same time, the through hole structure can store more lubricating oil and enhance the oil absorption capacity; when the suction device is working, the lubricating oil in the through holes is more easily sucked away and discharged; 4. Figure 6 The placement gap 26 in the middle is the space for accommodating the bearing seat 6.

[0022] As a preferred implementation in this embodiment, an oil removal unit is further provided for removing the lubricating oil adsorbed on the oil absorption layer 18 .

[0023] The lubricating oil attached to the oil absorbing layer 18 can be automatically removed by the oil removal unit, so that the oil absorbing layer 18 always maintains a good oil absorption effect, which is conducive to wiping the lubricating oil on the bearing seat 6 clean.

[0024] As a preferred embodiment of this embodiment, the oil removal unit includes a plurality of upper oil suction pipes 15 arranged circumferentially on the periphery of the upper support net 16 and a plurality of lower oil suction pipes 21 arranged circumferentially in the inner cavity of the lower support net 20; The lower ends of the multiple groups of upper oil suction pipes 15 are connected to the upper ring pipe 19, and the air extraction end of the upper ring pipe 19 is connected to the upper pipeline 14 installed on the protective cover 4. The multiple groups of upper oil suction pipes 15 are fixed to the inner wall of the protective cover 4 through the upper connecting rod 17; The lower ends of the multiple sets of lower oil suction pipes 21 are connected to the lower annular pipe 22, and the air extraction end of the lower annular pipe 22 is connected to the lower pipe 8 installed on the groove plate 7. The multiple sets of lower oil suction pipes 21 are connected to the outer wall of the bearing 24 through the lower connecting rod 23, and the bearing 24 is installed on the drive shaft of the lower motor 26; The multiple groups of upper oil suction pipes 15 and the multiple groups of lower oil suction pipes 21 are provided with oil suction holes on their end surfaces close to the oil suction layer 18; The mounting ends of the upper pipe 14 and the lower pipe 8 are connected to the suction device. When the suction device is working, a strong suction force can be generated in the upper pipe 14 and the lower pipe 8, thereby sucking away the lubricating oil on the oil absorption layer 18; There are two groups of suction devices, which include a rotating shaft 9 rotatably arranged on the base 1. The rotating shaft 9 is driven by a driving motor installed on the base 1. Two groups of crankshafts are arranged on the rotating shaft 9, one above and one below. Both groups of crankshafts are movably provided with movable rods 10, and the lower ends of the movable rods 10 are movably connected to pistons, and the pistons are movably installed in corresponding piston cylinders 11. The piston cylinders 11 are respectively provided with an outlet pipe 13 and an exhaust pipe 12, and the outlet pipe 13 and the exhaust pipe 12 are respectively provided with an outlet check valve and an inlet check valve.

[0025] Before use, connect the two suction pipes 12 of the same suction device to the upper pipe 14 (a Y-shaped pipe), connect the two suction pipes 12 of the other suction device to the lower pipe 8 (a Y-shaped pipe), and connect all four sets of air outlet pipes 13 to the oil receiving barrel. In use, when the upper motor 5 or the lower motor 26 works to drive the oil absorption layer 18 to rotate, the driving motor electrically connected to the controller is controlled to work, driving the rotating shaft 9 to rotate, and the two crankshafts located on the same rotating shaft 9 will drive the two movable rods 10 to move up and down, thereby continuously generating suction in the upper oil absorption pipe 15 and the lower oil absorption pipe 21, and absorbing oil from the rotating upper support net 16 and the oil absorption layer 18 on the lower support net 20. Since the upper support net 16 and the lower support net 20 are rotating, the upper suction pipe with suction can be The oil pipe 15 and the lower oil suction pipe 21 perform comprehensive oil absorption treatment on the oil absorption layer 18, and during the oil absorption process, the centrifugal force generated by the rotation of the oil absorption layer 18 helps to separate the lubricating oil from the oil absorption layer 18, and the shear stress generated by the rotation will destroy the viscous layer of the oil film on the surface of the oil absorption layer 18, which is more conducive to the upper oil suction pipe 15 and the lower oil suction pipe 21 to absorb oil, and the oil removal treatment is performed when the oil absorption layer 18 rotates to process the lubricating oil on the surface of the bearing seat 6, which can improve the oil absorption effect of the oil absorption layer 18 on the bearing seat 6 and better wipe the lubricating oil of the bearing seat 6.

[0026] It should be noted that when the upper support net 16 and the lower support net 21 stop working, their suction devices also stop working.

[0027] As a preferred implementation in this embodiment, a limiting unit is further provided to ensure that the bearing seat 6 remains stable when the oil absorption layer 18 rotates and wipes the bearing seat 6.

[0028] As a preferred implementation in this embodiment, the limiting unit includes two groups of magnetic blocks 27 , and the two groups of magnetic blocks 27 are symmetrically arranged in the grooves at the top of the inner cavity of the protective cover 4 , and the magnetic blocks 27 are arranged opposite to the upper support net 16 .

[0029] The setting of the magnetic block 27 has an upward force on the bearing seat 6 (this force is not greater than the gravity of the bearing seat 6). In the optimal state, this upward force is consistent with the gravity of the bearing seat 6 to form a counteraction. The friction force between the oil-absorbing layer 18 located above and the upper end surface of the bearing seat 6 is equal to the friction force between the oil-absorbing layer 18 located below and the lower end surface of the bearing seat 6, forming a force offset, which can further improve the stability of the bearing seat 6. There can be an error of plus or minus 5%, which can ensure that the bearing seat can maintain good stability throughout the process.

[0030] It should be noted that since the two magnetic blocks 27 are symmetrically arranged, the bearing seat 6 will be affected by magnetic resistance when it rotates, and the rotation of the bearing seat 6 is suppressed by the magnetic resistance, which is beneficial to the stability of the bearing seat 6.

[0031] As a preferred implementation in this embodiment, the symmetry centers of the two magnetic blocks 27 are on the same vertical line as the axes of the upper support net 16 , the lower support net 20 , the drive shaft of the upper motor 5 , and the drive shaft of the lower motor 26 .

[0032] The coaxial design effectively avoids additional stress caused by axis deviation, making the equipment run more stable.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
