Description

Technical Field

[0001] This application relates to the field of powder metallurgy bearing technology, specifically to a powder metallurgy oil-impregnated bearing cleaning device. Background Technology

[0002] Powder metallurgy bearings are made by pressing, sintering, shaping, and oil impregnation of metal powder and other anti-friction material powders. They have a porous structure. After being impregnated in hot oil, the pores are filled with lubricating oil. During operation, due to the suction effect of the journal rotation and the heat generated by friction, the metal and oil expand due to heat, squeezing the oil out of the pores, thus providing lubrication to the friction surfaces. After the bearing cools down, the oil is drawn back into the pores. It has the technical advantage of being able to freely adjust the number, size, shape, and distribution of pores during the manufacturing process.

[0003] Meanwhile, after prolonged use, powder metallurgy bearings need to be cleaned to thoroughly remove oil stains from the bearing surface. Currently, bearing cleaning devices are commonly used to clean oil-impregnated bearings.

[0004] For example, the patent with publication number CN215508005U discloses a cleaning device for powder metallurgy oil-impregnated bearings. While cleaning multiple oil-impregnated bearings in batches, it also thoroughly cleans the outer ring, inner wall and pores of the oil-impregnated bearings, further improving the cleaning effect and work efficiency. After cleaning, the limiting structure is removed together with the clean oil-impregnated bearings to avoid secondary contamination of the oil-impregnated bearings.

[0005] In the aforementioned patent, the device achieves batch cleaning of oil-impregnated bearings by setting up a cleaning mechanism. However, when the device brushes the bearings, since the bearings are clamped onto the rotating rod, the bottom surface of the bearings will contact the rotating rod. At this time, the cleaning brush cannot clean the bottom surface, resulting in a cleaning blind spot. When the bearings are clamped onto the rotating rod for cleaning, the contact between the bottom surface of the bearings and the rotating rod may cause residual lubricating oil or impurities on the bottom surface of the bearings, affecting the subsequent performance and life of the bearings. Therefore, it is necessary to provide a powder metallurgy oil-impregnated bearing cleaning device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figure 1 As shown, this application provides a powder metallurgy oil-impregnated bearing cleaning device, including a workbench 1, which is set in a bearing processing plant, and a cleaning mechanism 2 is set on the top of the workbench 1. The cleaning mechanism 2 is used to clean the powder metallurgy oil-impregnated bearing (hereinafter referred to as the bearing) to prevent oil stains from remaining on the bearing surface.

[0027] like Figures 2-3As shown, the cleaning mechanism 2 includes a turntable 21, which is connected to the top of the workbench 1 by a bearing. Multiple sets of snap-fit ​​components 3 are provided on the turntable 21 to fix the bearing. A drive motor is provided inside the workbench 1, and the output end of the drive motor is connected to the bottom of the turntable 21 to drive the turntable 21 to rotate on the workbench 1.

[0028] Meanwhile, two sets of cleaning sections 4 are provided on the outside of the workbench 1. Each cleaning section 4 includes a fixed frame 41, on which a connecting plate 42 is slidably mounted. A rotating handle 411 is rotatably connected to the top of the fixed frame 41, and the bottom of the rotating handle 411 is threadedly connected to the connecting plate 42, so that the connecting plate 42 is suitable for moving on the fixed frame 41 under the drive of the rotating handle 411.

[0029] Meanwhile, a rotary motor 43 is fixedly installed on the connecting plate 42. A cleaning brush 44 is fixedly installed at the output end of the rotary motor 43. The cleaning brush 44 is used to clean the bearing. At the same time, spray pipes 45 are provided on both sides of the rotary motor 43. The spray pipes 45 are connected to an external water source and are used to spray clean water or cleaning liquid onto the bearing to achieve a thorough cleaning of the bearing.

[0030] like Figures 4-5 As shown, the snap-fit ​​assembly 3 includes a base 31, which is fixedly installed on the top of the turntable 21. A clamping part is provided on the base 31, which includes two sets of fixing posts 32. A first connecting rod 33 is slidably inserted into one set of fixing posts 32. A plurality of through holes (not shown in the figure) are provided on one side of the first connecting rod 33, and an arc-shaped first locking block 331 is bearing connected to the other side of the first connecting rod 33. The first locking block 331 is used to contact the bearing.

[0031] Meanwhile, a mounting base 34 is provided on the fixed post 32, and a plug-in post 35 is slidably disposed in the mounting base 34. The size of the plug-in post 35 is adapted to the size of the through hole, and is used to fix the position of the first connecting rod 33.

[0032] Meanwhile, a second connecting rod 36 is installed in the bearing of another set of fixed columns 32. A second locking block 361 is fixedly installed on one side of the second connecting rod 36. The second locking block 361 has the same configuration as the first locking block 331.

[0033] When it is necessary to fix the bearing, the operator first presses the bearing against the outer wall of the second clamping block 361, then controls the first connecting rod 33 to move toward the second clamping block 361, so that the bearing is clamped between the first clamping blocks 361. Then, the insertion post 35 is inserted into the corresponding through hole in the first connecting rod 33, so that the position of the first connecting rod 33 is fixed, thereby fixing the bearing. After the bearing is installed, it will not rotate in the clamping assembly 3 due to gravity or the movement of the turntable 21, ensuring the cleaning effect.

[0034] Meanwhile, a gear 6 is fixedly installed on the other side of the second connecting rod 36. This gear 6 can be a helical gear.

[0035] like Figures 2-5 As shown, a fixing plate 5 is provided on the workbench 1 between the two sets of cleaning sections 4. An arc-shaped rack 51 is fixedly installed on the top of the fixing plate 5. The rack 51 is adapted to mesh with the gear 6, and the length of the rack 51 is half the circumference of the gear 6.

[0036] When the bearing needs to be cleaned, first place the bearing to be cleaned into the multiple sets of locking assemblies 3 on the top of the turntable 21 and lock them. Then start the turntable 21 so that the locking assemblies 3 rotate toward the two sets of cleaning sections 4. When the bearing passes the first set of cleaning sections 4, the cleaning section 4 will brush one side of the bearing in the locking assembly 3. Then, as the turntable 21 continues to rotate, the locking assembly 3 will move to the fixed plate 5. At this time, the gear 6 in the locking assembly 3 will contact the rack 51. Then, as the turntable 21 rotates, it will drive the gear 6 to rotate, thereby causing the bearing to rotate 180 degrees. Then the bearing will enter the other set of cleaning sections 4 for the second side to be brushed, thus ensuring a thorough cleaning of the bearing and improving cleaning efficiency and thoroughness.

[0037] In summary, this device, by setting up the snap-fit ​​assembly 3, enables the bearing to be securely clamped. At the same time, by setting up the turntable 21 and the rack 51, the bearing in the snap-fit ​​assembly 3 can be rotated 180 degrees after one rinse, so as to rinse the other side, making the cleaning process more efficient and comprehensive.

[0038] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
