[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1-3 As shown, Figure 1 Structural layout diagram of the bearing cage cleaning and oil spraying equipment provided in this application; Figure 2 for Figure 1 Schematic diagram of the structure of the cage support platform; Figure 3 for Figure 2 Cross-sectional view of the internal structure of the cage support platform.

[0039] This application provides a bearing cage cleaning and oil spraying device, including a cage support platform 2, arranged radially at the center of the bearing cage 1, and having a rotating seat 21 for suspending the bearing cage 1 radially inward; a cleaning unit 3 located on a first side of the cage support platform 2, the cleaning unit 3 having a cleaning channel for accommodating a portion of the bearing cage 1 and cleaning that portion of the bearing cage 1; and an oil spraying unit 4 located on a second side of the cage support platform 2, the oil spraying unit 4 having an oil spraying channel for accommodating a portion of the cleaned bearing cage and spraying oil onto that portion of the cleaned bearing cage. The bearing cage 1 is suspended by the cage support platform 2, the bearing cage 1 is arranged laterally in the radial direction, and is rotated by the rotating seat 21. A cleaning unit 3 and an oil spraying unit 4 are installed on the first and second sides of the cage support platform 2. During the rotation of the bearing cage 1, cleaning and oil spraying are performed on it. The cage support platform 2 supports the bearing cage 1 and drives it to rotate synchronously. The cleaning unit 3 and the oil spraying unit 4 perform synchronous cleaning and oil spraying on the rotating bearing cage 1. By supporting the large bearing cage by rotation, the bearing cage is cleaned by local cleaning and oil spraying to meet the cleaning requirements.

[0040] This embodiment provides a bearing cage cleaning and oil spraying device. For large bearing cages 1 with a large radial dimension span, the device simultaneously performs the cleaning of the bearing cage 1 and the oil spraying of the cleaned bearing cage 1.

[0041] From the structural layout of the cleaning and oiling equipment, to accommodate the radial span of the bearing cage 1, the bearing cage 1 is treated by localized cleaning and oiling. Specifically, the bearing cage 1 is supported by a cage support platform 2, which includes a platform body and a rotating seat 21 located on top of the platform body. Multiple lifting arms 22 extend evenly from the rotating seat 21. The extended ends of each lifting arm 22 clamp and support the inner ring of the bearing cage 1. At the same time, the rotating structure of the rotating seat 21 allows the bearing cage 1 to rotate according to a predetermined cycle.

[0042] Meanwhile, the cleaning and oiling processes are arranged independently and set on the first and second sides of the bearing cage 1 circumferentially after the bearing cage 1 is installed on the cage support platform 2. The cleaning and oiling processes are set sequentially. After the bearing cage 1 is cleaned, the subsequent oiling process is carried out to spray oil on the bearing cage.

[0043] In a preferred embodiment, the cage support platform 2 includes a cage body 23, a rotating frame disposed on the cage body 23, and a drive structure for driving the rotating frame to rotate is disposed inside the cage body 23.

[0044] The rotating frame is arranged on the top of the retainer platform 23, including a rotating base 21 and multiple lifting arms 22 extending radially along the rotating base 21, the extension length of the lifting arms 22 being adjustable.

[0045] A slewing bearing 24 is provided between the rotating base 21 and the rotating frame, and the rotating base 21 is mounted on the top of the rotating frame through the slewing bearing 24.

[0046] In this embodiment, the retainer platform 23 is a frame structure retainer platform. The top of the retainer platform 23 is configured as a support platform 231. The middle of the support platform 231 is provided with a bearing mounting hole for mounting the slewing bearing 24. The rotating seat 21 is mounted on the top of the retainer platform 23 through the slewing bearing 24. The retainer platform 23 has a drive structure inside, which includes a drive motor 25 and a drive gear located at the output end of the drive motor 25, which is in gear transmission engagement with the inner ring of the slewing bearing 24.

[0047] The lifting boom 22 includes a main support boom 221 fixedly connected to the rotating seat 21, and an extension support boom 222 telescopically arranged on the main support boom 221. A hook 223 is arranged on the extension support boom 222, and the hook 223 is used to cooperate with the bearing cage 1 for lifting.

[0048] In an optional structure, both the main support arm 221 and the extension support arm 222 can be configured as square tubes and fitted together, allowing the extension support arm 222 to extend or retract onto the main support arm 221. An extension scale is provided on the extension support arm 222 for precise control of the extension length. Alternatively, the main support arm 221 and the extension support arm 222 can also employ a slider-rail cooperation structure, or a sliding track structure between them.

[0049] Furthermore, the extended support arm 222 can be configured as a multi-segment telescopic structure for hoisting and mounting large bearing support frames.

[0050] To accommodate the size specifications of large bearing cages, the cage support platform 2 is located at the center of the bearing cage 1 when the bearing cage 1 is being hoisted. Multiple hoisting arms 2 on the rotating seat 21 extend out, and the hooks 223 at the extended ends of the hoisting arms 2 are used to hoist the bearing cage 1 circumferentially at multiple points.

[0051] In this specific structure of embodiment one, the bearing cage 1 is a tapered roller cage, making the cross-section of the bearing cage 1 inclined. The small diameter end of the bearing cage 1 is set as an inclined inner ring, and the large diameter end is set as an inclined outer ring. Multiple windows for placing bearing rollers are arranged between the inclined inner ring and the inclined outer ring. The hook 223 is hoisted on the inclined inner ring of the bearing cage 1, so that the bearing cage 1 is arranged in a positive tapered structure and is driven to rotate by the cage support platform.

[0052] like Figure 4 and Figure 5 As shown, Figure 4 A structural layout diagram of the cleaning unit in the bearing cage cleaning and oil spraying equipment provided in this application; Figure 5 for Figure 4 A schematic diagram of the cleaning structure of the cleaning unit.

[0053] In a preferred embodiment of this invention, the cleaning process and the oil spraying process are respectively located on the first and second sides of the bearing cage's radial direction. The cleaning process involves cleaning unit 3 cleaning the hoisted bearing cage 1. The oil spraying process involves oil spraying unit 4 spraying oil onto the cleaned and dried bearing cage 1. Both cleaning unit 3 and oil spraying unit 4 perform processing on the bearing cage 1 by performing localized machining.

[0054] Specifically, the cleaning unit 3 includes a lower cleaning housing 32 and an upper cleaning housing 31. Both the lower cleaning housing 32 and the upper cleaning housing 31 have a lower cleaning slope and an upper cleaning slope corresponding to the slope of the bearing cage 1. The lower cleaning housing 32 and the upper cleaning housing 31 are arranged opposite to each other through the lower cleaning slope and the upper cleaning slope, and the upper cleaning slope and the lower cleaning slope form a cleaning channel 33 for part of the bearing cage 1 to pass through.

[0055] Both the lower cleaning housing 32 and the upper cleaning housing 31 are hollow structures. In the rotation direction of the bearing cage 1, the bearing cage 1 is rotated into the cleaning inlet 331 of the cleaning channel and rotated out from the cleaning outlet 332. The upper cleaning housing 32 and the lower cleaning housing 31 surround part of the inner ring of the bearing cage 1 inside the housing. Through the interval arrangement of the cleaning inlet 331 and the cleaning outlet 332, part of the arc section of the bearing cage 1 is accommodated.

[0056] A lower cleaning nozzle 321 is arranged inside the lower cleaning housing 32 to spray and clean the inner side of the bearing cage, and an upper cleaning nozzle 311 is arranged inside the upper cleaning housing 31 to spray and clean the outer side of the bearing cage 1.

[0057] Multiple sets of drying air knives for blowing and drying the bearing cage 1 are also arranged near the cleaning outlet 332 on the lower housing 32 and the upper housing 31. The drying air knives include strip-shaped air nozzles arranged along the width direction of the bearing cage 1, and two sets arranged in parallel in the rotation direction of the bearing cage 1. The two sets of drying air knives include a lower drying air knife 341 located on the inner side of the bearing cage 1, and an upper drying air knife 342 located on the outer side of the bearing cage 1.

[0058] The cleaning unit 3 also includes a cleaning platform 35, with an upper cleaning housing 31 and a lower cleaning housing 32 arranged on the cleaning platform 35. The cleaning platform 35 is also equipped with a circulation pump 37 that connects the upper cleaning nozzle 311 and the lower cleaning nozzle 321 and supplies cleaning fluid. The circulation pump 37 is connected to a cleaning fluid recovery tank inside the cleaning platform 35. The cleaning platform 35 is provided with a cleaning fluid recovery port that connects the interior of the upper cleaning housing 31 and the lower cleaning housing 32 and recovers the liquid sprayed from the cleaning unit.

[0059] The cleaning unit is also equipped with an air knife supply fan 36 connected to the drying air knife. The air knife supply fan 36 has an adjustable air speed and is equipped with a peak-shaving valve to control the air pressure supplied by the drying air knife, thus blowing away moisture and oil stains from the surface of the bearing cage 1. To prevent the spread of the swept oil mist, an oil mist filter is installed on the cleaning platform 35. The oil mist filter is connected to the inside of the axial flow fan to simultaneously extract the swept oil mist, separating and filtering the oil mist and moisture to ensure environmental safety.

[0060] like Figures 6-8 As shown, Figure 6 A structural layout diagram of the cleaning unit in the bearing cage cleaning and oil spraying equipment provided in this application; Figure 7 for Figure 6 A schematic diagram of the cleaning structure of the intermediate cleaning unit; Figure 8 for Figure 6 Forward structural layout diagram of the cleaning unit.

[0061] The oil injection unit is also provided with a lower oil injection housing 42 and an upper oil injection housing 41. The lower oil injection housing 42 and the upper oil injection housing 42 form an oil injection channel 43 for the passage of the partially cleaned bearing cage 1. An oil injection area and a drying area are arranged sequentially in the oil injection channel 43, and a partition baffle is provided between the oil injection area and the drying area.

[0062] The oil spraying area is equipped with a lower spray gun 421 for spraying oil onto the inner surface of the bearing cage 1 and an upper spray gun 411 for spraying oil onto the outer surface of the bearing cage 1. The upper spray gun 411 and the lower spray gun 421 simultaneously spray oil onto both the inner and outer surfaces of the bearing cage 1. The cleaning angle of the lower spray gun 421 relative to the inner surface of the bearing cage 1 is set, and the tilt angle of the upper spray gun 411 relative to the outer surface of the bearing cage 1 is set. The spray width and height of the upper spray gun 411 and the lower spray gun 421 are controlled to maximize the spraying area and achieve the best spraying effect on the bearing cage.

[0063] Preferably, the spraying distance between the upper spray gun 411 and the lower spray gun 421 is 170mm to 230mm. The spray width of the upper spray gun 411 and the lower spray gun 421 is 140mm to 230mm. Both the upper spray gun 411 and the lower spray gun 421 also have adjusting rods that support the spray gun head 4214. The adjusting rods include a vertically arranged height adjusting rod 4211, a lockable slider 4212 slidably arranged on the height adjusting rod 4211, and a laterally extending angle adjusting rod 4213 extending from the slider 4212. The spray gun head 4214 on the upper spray gun 411 and the lower spray gun 421 is rotatably connected to the angle adjusting rod 4212.

[0064] By setting a height adjustment rod 4211 and an angle adjustment rod 4213 connected by a slider 4212, the oil spraying height and oil spraying angle of the upper spray gun 41 and the lower spray gun 42 are controlled to meet the oil spraying requirements of different types of bearing cages.

[0065] The drying area is also equipped with two sets of oil spraying air knives 44, arranged side by side, with the two sets of oil spraying air knives 44 spaced apart in the rotation direction of the bearing cage 1. Each set of oil spraying air knives 44 includes two knives arranged opposite each other on the inner and outer sides of the bearing cage. Simultaneously, each oil spraying air knife 44 has a strip-shaped air outlet extending along the width direction of the bearing cage 1, allowing for overall air blowing along the width of the bearing cage 1. By using two sets of oil spraying air knives 44 to blow air along the thickness of the bearing cage 1 in two directions, the surface of the bearing cage is simultaneously blown, resulting in a more uniform oil film.

[0066] The oil injection unit also includes an oil injection platform 45, an upper oil injection housing 41 and a lower oil injection housing 42 fixedly mounted on the oil injection platform 45, and an oil injection cabinet 46 arranged on the oil injection platform 45. The oil injection cabinet 46 is located on the side of the oil injection unit away from the bearing cage 1. The upper oil injection housing 41 has ventilation holes 49, specifically arranged on the back side of the upper oil injection housing 41. Correspondingly, the side of the oil injection cabinet 46 is connected to the interior of the upper oil injection housing 41.

[0067] The fuel injection cabinet 46 has multiple layers of mesh 48 inside, with oil filter cotton filling the spaces between adjacent meshes 48. The bottom of the fuel injection cabinet 46 is connected to the ventilation holes 49 on the upper fuel injection housing 41, and a fan 47 is installed on the top of the fuel injection cabinet 46. Preferably, the fan 47 is an axial flow fan, and a conical suction channel is provided on the top of the fuel injection cabinet 46. The axial flow fan provides airflow to the fuel injection channel. During the fuel injection process, the oil mist in the fuel injection channel is extracted and enters the fuel injection cabinet 46 through the ventilation holes 49 of the upper fuel injection housing 41. The oil mist is then filtered by the oil mist filter cotton inside the fuel injection cabinet 46, achieving oil mist recovery.

[0068] A fuel supply system, including a fuel tank and fuel injection pipes connecting the fuel tank to the upper and lower spray guns, is installed on one side of the fuel injection platform 45. The fuel injection platform also has a fuel collection trough 431, located at the bottom of the upper and lower fuel injection housings 41 and 42, to collect fuel mist falling from the bearing cage. An air knife blower is installed on the other side of the fuel injection platform to provide the airflow for the fuel injection air knife.

[0069] The lifting radius of the cage rotation platform is adjustable, and bearing cages of different inner diameters can be lifted via the support arm. Therefore, the positions of the cleaning unit and the oil injection unit need to be adjusted. In this embodiment, a linear guide rail 5 is also provided at the bottom of the cleaning unit and the oil injection unit. The bottom of both the cleaning unit 3 and the oil injection unit 4 has traveling wheels that cooperate with the linear guide rail. The cleaning unit and the oil injection unit also have brake casters for walking and moving support.

[0070] When adjusting the positions of cleaning unit 3 and oil injection unit 4, release the brake casters of cleaning unit and oil injection unit, push cleaning unit and oil injection unit to move on linear guide rail 5, adjust cleaning unit and oil injection unit to the predetermined position according to the size of bearing cage, and then brake cleaning unit and oil injection unit.

[0071] Then, adjust the lifting arm 22 on the cage rotation platform 2 to extend to the predetermined length, hang the bearing cage 1 to be processed on the hook of the lifting arm, and adjust the bearing cage 1 to fall into the cleaning channel 33 and the oil spraying channel 43, so that the bearing cage 1 can enter the subsequent cleaning process and oil spraying process to process the bearing cage 1.

[0072] In one specific embodiment of this case, a leak-proof tray 6 is also included. The leak-proof tray 6 is laid flat on both sides of the linear guide rail 5 and distributed below the cleaning unit 3 and the oil spraying unit 4. Although the bearing cage 1 is dried by the blower and the oil spraying knife, water droplets or oil may still remain on the bearing cage. By setting up the leak-proof tray, the dripping water droplets and oil are collected, thereby improving the cleanliness of the environment.

[0073] In one specific embodiment of this case, a demagnetizer is also included. The demagnetizer has a demagnetizer frame, and a demagnetizer head is provided on the demagnetizer frame. The demagnetizer head has an inner demagnetizing end face and an outer demagnetizing end face that face the inner and outer sides of the bearing cage. The demagnetizer head is used to perform local demagnetization on the bearing cage, so as to avoid the inability to remove iron filings carried on the surface of the bearing cage.

[0074] Iron filings are removed from the surface of the bearing cage by a demagnetizer. A local cleaning machine is set up to spray the product with 360° high pressure through precision transmission to remove oil and impurities from the product surface. Local air cutting and heating are set up. The product is first air cut to avoid leaving marks due to heating, and then heated to evaporate water stains on the product surface. Oiling is set up to prevent the cage from rusting.

[0075] The following steps are used when cleaning and spraying the bearing cage using the aforementioned bearing cage cleaning and oiling equipment:

[0076] S1: The bearing cage is hoisted and supported so that it rotates along the radial center;

[0077] The bearing cage 1 is supported by a cage support platform 2. The cage support platform 2 includes a cage base 23 located at the center of the bearing cage 1. A rotating seat 21 is mounted on the cage base 23, and multiple lifting arms 22 extend from the rotating seat 21. After adjusting the main support arm 221 and extending the support arms 222 to a predetermined length, the bearing cage is lifted by the hooks 223. The rotating seat 21 is driven to rotate by a drive device to meet the cycle requirements of cleaning and oiling.

[0078] S2: A cleaning unit is arranged at the first circumferential position of the bearing cage 1 after hoisting to perform local cleaning on the rotating bearing cage;

[0079] After adjusting the bearing cage 1 to the predetermined length, the bearing cage 1 falls into the cleaning channel 33. The cleaning channel 33 is equipped with cleaning nozzles and drying air knives. The bearing cage 1 is cleaned and dried simultaneously in the cleaning channel 33. After the partial cleaning and drying of the bearing cage 1, it is transferred out of the cleaning channel 33 and transferred to the oil spraying unit for oil spraying.

[0080] S3: An oil spraying unit is arranged at the second circumferential position of the bearing cage, and the cleaning unit and the oil spraying unit are arranged sequentially in the rotation direction of the bearing cage.

[0081] The oil spraying unit 4 is arranged after the cleaning process of the cleaning unit 3. After cleaning and drying, the bearing cage 1 is further transferred into the oil spraying unit 4. The oil spraying unit 4 performs oil spraying and drying operations, so that the oil film is evenly sprayed on the surface of the bearing cage 1.

[0082] The oil spraying unit performs localized oil spraying on the bearing cage after localized cleaning;

[0083] Repeat the above local cleaning and local oiling process until the bearing cage is coated with oil in all directions.

[0084] Because the bearing cage 1 is cleaned and oiled in a localized manner, the cleaning and oiling process is repeated segment by segment. The cleaning and oiling are completed after the bearing cage rotates one revolution. It is understood that this application preferably places the cleaning unit 2 and the oiling unit 3 at both ends of the linear guide rail extension direction. After completing one revolution of cleaning and oiling of the bearing cage 1, the surface of the bearing cage 2 undergoes two cleaning and coating processes, ensuring surface cleanliness.

[0085] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
