Description

Technical Field

[0001] This utility model relates to the field of bearing housing production technology, and in particular to a bearing housing degreasing device. Background Technology

[0002] The bearing housing for idler rollers is usually formed from metal discs through multiple stamping, stretching, shaping, punching, and trimming steps using a mold.

[0003] When bearing housings undergo multiple stamping and stretching processes, liquid lubricating oil is used to lubricate the unformed bearing housings before each stamping. The lubricating oil forms a lubricating film on the contact surface, which can effectively reduce the coefficient of friction, reduce resistance during the stretching process, and prevent the material from breaking or deforming unevenly due to excessive friction. After the bearing housing is formed, it is usually necessary to manually wipe off the lubricating oil adhering to the inside and outside of the bearing housing with a cloth. This is labor-intensive and inefficient. Therefore, this application provides a bearing housing degreasing device to meet the requirements. Utility Model Content

[0006] The wiping unit includes a drive cylinder mounted on a mounting plate, a protective cover fixedly connected to the output end of the drive cylinder via a connecting rod, and a grooved plate located directly below the protective cover and having a groove.

[0007] Both the mounting plate and the grooved plate are disposed on the base;

[0008] An upper motor is installed at the upper end of the protective cover, and the output shaft of the upper motor passes through the protective cover and is fixedly connected to the upper support mesh. The upper support mesh is adapted to the upper surface of the bearing seat.

The multiple sets of upper oil suction pipes are fixed to the inner wall of the protective cover by the upper connecting rod.

[0013] The lower ends of the multiple sets of lower suction pipes are all connected to the lower ring pipe, the air extraction end of the lower ring pipe is connected to the lower pipe installed on the groove plate, the multiple sets of lower suction pipes are all connected to the outer wall of the bearing through the lower connecting rod, and the bearing is installed on the drive shaft of the lower motor;

[0014] Oil suction holes are provided on the end faces of the multiple sets of upper oil suction pipes and multiple sets of lower oil suction pipes near the oil suction layer;

[0015] The upper pipe and the lower pipe are both connected to a suction device. When the suction device is working, it can generate a strong suction in the upper pipe and the lower pipe, thereby sucking away the lubricating oil on the oil absorption layer.

[0016] The suction device includes a rotating shaft rotatably mounted on the base. The rotating shaft is driven by a drive motor mounted on the base.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making inventive efforts are within the protection scope of the present utility model.

[0031] Example: Reference Figure 1-4 The bearing housing degreasing device shown includes a wiping unit and a degreasing unit.

[0032] The wiping unit includes a drive cylinder 3 mounted on the mounting plate 2, a protective cover 4 fixedly connected to the output end of the drive cylinder 3 via a connecting rod, and a grooved plate 7 located directly below the protective cover 4 and having a groove.

[0033] Both mounting plate 2 and grooved plate 7 are mounted on base 1;

[0034] 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.

[0035] The groove of the groove plate 7 is provided with a lower support net 20 that is adapted to the inner surface of the bearing seat 6. An oil-absorbing layer 18 is provided on the outer surface of the lower support net 20 and the inner surface of the upper support net 16.

[0036] A lower motor 26 is installed on the base 1, and the output shaft of the lower motor 26 passes through the groove plate 7 and is fixedly connected to the lower support net 20;

[0037] The oil removal unit includes multiple sets of upper oil suction pipes 15 arranged in a circle around the upper support net 16 and multiple sets of lower oil suction pipes 21 arranged in a circle inside the lower support net 20.

[0038] The lower ends of multiple sets of upper suction pipes 15 are all connected to upper ring pipes 19. The suction end of upper ring pipes 19 is connected to upper pipes 14 installed on protective cover 4. Multiple sets of upper suction pipes 15 are fixed to the inner wall of protective cover 4 through upper connecting rods 17.

[0039] The lower ends of multiple sets of lower suction pipes 21 are all connected to the lower ring pipe 22. The suction end of the lower ring pipe 22 is connected to the lower pipe 8 installed on the groove plate 7. Multiple sets of lower suction pipes 21 are all connected to the outer wall of the bearing 24 through the lower connecting rod 23. The bearing 24 is installed on the drive shaft of the lower motor 26.

[0040] Oil suction holes are provided on the end faces of multiple sets of upper oil suction pipes 15 and multiple sets of lower oil suction pipes 21 near the oil suction layer 18;

[0041] The installation ends of the upper pipe 14 and the lower pipe 8 are both connected to the suction device. When the suction device is working, it can generate a strong suction in the upper pipe 14 and the lower pipe 8, thereby sucking away the lubricating oil on the oil absorption layer 18.

[0042] The suction device includes a rotating shaft 9 rotatably mounted on a base 1. The rotating shaft 9 is driven by a drive motor mounted on the base 1. Two sets of crankshafts are arranged one above the other on the rotating shaft 9. Each set of crankshafts is movably mounted with a movable rod 10. The lower end of the movable rod 10 is movably connected to a piston, which is movably mounted in a corresponding piston cylinder 11. An air outlet pipe 13 and an air extraction pipe 12 are respectively provided on the piston cylinder 11. An air outlet check valve and an air inlet check valve are respectively provided on the air outlet pipe 13 and the air extraction pipe 12.

[0043] In actual use, the wiping unit is manually placed after the bearing seat 6 is 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). By manually pressing the start button of the controller, the drive cylinder 2 drives the protective cover 4 to move downward, and finally makes the upper oil-absorbing layer 18 contact the upper surface of the bearing seat 6. At this time, the upper motor 5 and the lower motor 26 work, respectively driving the upper oil-absorbing layer 18 to rotate clockwise at low speed and driving the lower oil-absorbing layer 18 to rotate counterclockwise at low speed. The upper and lower oil-absorbing layers 18 rotate in opposite directions, and some of the friction forces cancel each other out, which helps to maintain 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 wiped bearing seat 6. The automated operation of this equipment replaces manual wiping, significantly reducing labor intensity and increasing efficiency several times compared to manual wiping.

[0044] Before using the oil removal unit, connect the two suction pipes 12 of the suction device to the upper pipe 14 and the lower pipe 8 respectively, and connect both sets of air outlet pipes 13 to the oil receiving tank.

[0045] In operation, when the upper motor 5 or the lower motor 26 drives the oil suction layer 18 to rotate, the drive motor electrically connected to the controller operates, driving the rotating shaft 9 to rotate. The two crankshafts located on the same rotating shaft 9 will drive the two movable rods 10 to move up and down, thereby causing the upper oil suction pipe 15 and the lower oil suction pipe 21 to move in opposite directions. Intermittent suction is generated to absorb oil from the oil-absorbing layer 18 on the rotating upper support net 16 and lower support net 20. Because the upper support net 16 and lower support net 20 are rotating, the upper oil-absorbing pipe 15 and lower oil-absorbing pipe 21, which have suction power, can comprehensively absorb oil from the oil-absorbing layer 18. During the oil absorption process, the centrifugal force generated by the rotation of the oil-absorbing layer 18 helps separate the lubricating oil from the oil-absorbing layer 18. Furthermore, the shear stress generated by the rotation breaks down the viscous layer of the oil film on the surface of the oil-absorbing layer 18, making it more conducive to oil absorption by the upper oil-absorbing pipe 15 and lower oil-absorbing pipe 21. Moreover, oil removal is performed while the oil-absorbing layer 18 is rotating and processing the lubricating oil on the surface of the bearing housing 6, thereby improving the oil absorption effect of the oil-absorbing layer 18 on the bearing housing 6 and achieving a better wiping effect on the lubricating oil of the bearing housing 6.

[0046] It should be noted that: 1. The upper motor 5, lower motor 26, and drive cylinder 2 are all electrically connected to the controller; 2. The oil-absorbing layer 18 can be made of graphene-based polyurethane oil-absorbing sponge or polyester fiber material, which has a good oil absorption effect and also facilitates the subsequent separation of lubricating oil from the oil-absorbing layer 18 by suction; 3. Multiple tiny through holes can also be densely arranged on the oil-absorbing layer 18 to increase the contact area between the oil-absorbing layer 18 and the lubricating oil. At the same time, the through-hole structure can store more lubricating oil, enhancing 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 5 The placement gap 25 is a space to accommodate the bearing seat 6; fifth, when the upper support net 16 and the lower support net 21 stop working, their suction device also stops working.

[0047] As a preferred embodiment of this invention, a limiting unit is also provided to ensure that the bearing seat 6 remains stable and stationary when the oil-absorbing layer 18 rotates and wipes the bearing seat 6.

[0048] As a preferred embodiment of this example, Figure 3 As shown, the limiting unit includes two sets of magnetic blocks 27, and the two sets of magnetic blocks 27 are symmetrically arranged in the groove at the top of the inner cavity of the protective cover 4. The magnetic blocks 27 are arranged opposite to the upper support mesh 16.

[0049] The magnetic block 27 exerts an upward force on the bearing housing 6 (this force is no greater than the weight of the bearing housing 6). In the optimal state, this upward force is consistent with the weight of the bearing housing 6 and cancels it out. The friction between the upper oil-absorbing layer 18 and the upper end surface of the bearing housing 6 is equal to the friction between the lower oil-absorbing layer 18 and the lower end surface of the bearing housing 6, thus canceling out the forces. This can further improve the stability of the bearing housing 6. An error of ±5% is allowed, but it can ensure that the bearing housing can maintain good stability throughout the entire process.

[0050] It should be noted that, due to the symmetrical arrangement of the two magnetic blocks 27, the bearing housing 6 will be subjected to magnetic resistance when it rotates, thereby suppressing the rotation of the bearing housing 6 and contributing to the stability of the bearing housing 6.

[0051] In a preferred embodiment of this invention, the upper support mesh 16 is made of pure aluminum, and the protective cover 4 is made of magnetic shielding material.

[0052] The magnetic block 27 has a good magnetic effect on the upper support mesh 16 made of pure aluminum, which can reduce the rotational resistance of the drive shaft of the upper motor 5 and save energy. The protective cover 4 is supported by magnetic shielding material, which can prevent the magnetic leakage of the magnetic block 27 and avoid magnetic influence on the internal components of the upper motor 5.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
