Description

Technical Field

[0001] This utility model relates to the field of automotive bearing cleaning technology, specifically to an automotive bearing cleaning device. Background Technology

[0002] As a key component of core assemblies such as engines, transmissions, and chassis, automotive bearings are subjected to high temperatures, high pressures, aging grease, and metal debris contamination in their long-term working environment. If oil stains, iron filings, and other contaminants on the surface and in the gaps are not thoroughly removed, they will directly lead to increased wear, abnormal noises, shortened lifespan, and even mechanical failures after assembly. Therefore, bearing cleaning is a core process in the production and maintenance of automotive parts. The performance of the cleaning device directly determines the cleanliness of the bearing and its subsequent reliability. However, traditional cleaning technologies have gradually revealed problems such as low efficiency and insufficient cleanliness, making it difficult to meet the needs of modern production and maintenance. Therefore, there is a need for an automotive bearing cleaning device.

[0003] In existing automotive bearing cleaning devices, traditional rotary cleaning devices often have the spray system and bearing mounting rack rotating in the same direction or the spray head fixed, creating a co-current effect and hidden blind spots. This causes dirt to be trapped inside the liquid layer and unable to come into contact with fresh cleaning fluid. Even with extended cleaning time, it is difficult to remove the dirt, creating a vicious cycle of getting dirtier with each wash. Furthermore, it fails to promote the circulation and convection of the cleaning fluid within the tank, resulting in low cleaning efficiency. Therefore, there is an urgent need for an automotive bearing cleaning device. Summary of the Invention

[0004] Based on this, the purpose of this utility model is to provide an automotive bearing cleaning device to solve the problem that in existing automotive bearing cleaning devices, the spray system and the bearing placement rack are mostly rotating in the same direction or the spray head is fixed, forming a co-current effect and creating a hidden blind spot. This causes dirt to be wrapped inside the liquid layer and unable to come into contact with fresh cleaning liquid. Even if the cleaning time is extended, it is difficult to remove the dirt, forming a vicious cycle of getting dirtier the more you wash. In addition, it cannot promote the circulation and convection of the cleaning liquid in the tank, resulting in low cleaning efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive bearing cleaning device, comprising a cleaning tank, a drive motor fixedly connected to the bottom of the cleaning tank, a transmission rod fixedly connected to the drive motor via a coupling, an insert rod provided on the outer wall of the transmission rod, a nut installed on the top of the insert rod, a rotating rod installed on the outer wall of the transmission rod, a slot provided on the inner wall of the rotating rod, a stirring rod provided on the side wall of the rotating rod, a placement frame provided on the side wall of the rotating rod, a lead screw provided on the inner wall of the placement frame, and a fixed handle threadedly connected to the outer wall of the lead screw.

[0006] The top of the cleaning tank is equipped with a cover plate, and a stepper motor is fixedly connected to the top of the cover plate. The stepper motor is fixedly connected to a rotating rod through a coupling. A sliding groove is opened at the bottom of the cover plate, and a sprayer is fixedly connected to the bottom of the rotating rod. A slider is provided at the top of the sprayer.

[0007] Preferably, the rotating rod is connected to the transmission rod via a plug rod, and the rotating rod and the washing tub form a rotating structure via the transmission rod.

[0008] Preferably, the rotating rod forms a sliding structure with the slot via a plug rod, and the plug rod and slot are engaged.

[0009] Preferably, the inner wall of the nut is threaded, and the nut is threadedly connected to the transmission rod.

[0010] Preferably, the sprayer forms a rotating structure with the cover plate via a rotating rod, and the rotating rod is movably connected to the cover plate.

[0011] Preferably, the sprayer has a sliding structure formed by a slider and a groove, and the slider and groove are engaged and connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a drive motor, transmission rod, insert rod, nut, rotating rod, slot, stirring rod, and placement rack. By starting the drive motor, the stirring rod and placement rack on the rotating rod rotate synchronously, promoting the circulation and convection of the cleaning solution within the tank. Fresh cleaning solution continuously replenishes the bearing surface, while waste liquid carrying away dirt is quickly discharged or filtered, reducing secondary pollution. This achieves dynamic and efficient cleaning of bearings and convenient operation, significantly improving cleaning cleanliness and work efficiency. By rotating and removing the nut, the rotating rod can be removed from the transmission rod for maintenance or for loading and unloading bearings. This effectively solves the problems of low cleaning efficiency, excessive dirt residue, cumbersome loading and unloading, and inconvenient maintenance associated with traditional bearing cleaning devices. This invention utilizes a stepper motor, rotating rod, sliding groove, sprayer, and slider. By activating the stepper motor, the sprayer is driven to rotate along the sliding groove in the opposite direction to the rotating rod. This creates counter-current convection with the rotating bearing driven by the rotating rod. The counter-rotating sprayer causes the cleaning fluid to form a spiral convection, allowing droplets to penetrate the gaps from multiple angles. Especially effective against hidden oil stains between the rollers and the cage, the atomized droplets can penetrate more thoroughly and carry away the dirt, significantly improving the scouring power of the cleaning fluid on the bearing's dead corners. This achieves highly efficient cleaning of precision components, solves the problem of blind spots caused by the co-rotation of traditional equipment, and reduces the dirt residue rate.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0016] The embodiments of this utility model will be described below based on its overall structure.

[0017] Please see Figures 1-4A car bearing cleaning device includes a cleaning tank 1. A drive motor 2 is fixedly connected to the bottom of the cleaning tank 1. The drive motor 2 is fixedly connected to a transmission rod 3 via a coupling. An insert rod 4 is provided on the outer wall of the transmission rod 3. A nut 5 is installed on the top of the insert rod 4. A rotating rod 6 is installed on the outer wall of the transmission rod 3. A slot 7 is opened on the inner wall of the rotating rod 6. A stirring rod 8 is provided on the side wall of the rotating rod 6. A placement rack 9 is provided on the side wall of the rotating rod 6. A lead screw 10 is provided on the inner wall of the placement rack 9. A fixed handle 11 is threadedly connected to the outer wall of the lead screw 10. The rotating rod 6 is inserted into the transmission rod 3 via the insert rod 4, and the rotating rod 6 and the cleaning tank 1 form a rotating structure through the transmission rod 3. The rotating rod 6 and the slot 7 form a sliding structure through the insert rod 4, and the insert rod 4 and the slot 7 are engaged. The inner wall of the nut 5 is threaded, and the nut 5 is threadedly connected to the transmission rod 3. When using the device, the drive motor 2 is started, and the output shaft of the drive motor 2 drives the transmission rod 3 to rotate. Since the transmission rod 3 and the rotating rod 6 are connected, the stirring rod 8 and the placement frame 9 on the rotating rod 6 are rotated synchronously. When the placement frame 9 rotates, the bearing moves in a circular motion with it. The centrifugal force makes the oil on the bearing surface come into full contact with the cleaning fluid. At the same time, the high-speed rotation of the stirring rod 8 pushes the cleaning fluid to form a strong convection. The cleaning fluid in the center of the tank flows upward with the rotating rod 6, rebounds after passing through the tank wall, and then flows downward to replenish the bottom of the bearing, forming a circulating flow field with the center rising and the edges falling. The fresh cleaning fluid continuously washes the inner ring, outer ring, roller clearance, and surface grooves of the bearing, peeling off the oil, iron filings, and other dirt and carrying them into the waste liquid. Then, the nut 5 is removed by rotating, and the rotating rod 6 can be removed from the transmission rod 3 for maintenance or to load and unload the bearing.

[0018] Please see Figures 1-4 A car bearing cleaning device includes a cleaning tank 1 with a cover plate 12 installed on top. A stepper motor 13 is fixedly connected to the top of the cover plate 12. A rotating rod 14 is fixedly connected to the stepper motor 13 via a coupling. A sliding groove 15 is provided at the bottom of the cover plate 12. A sprayer 16 is fixedly connected to the bottom of the rotating rod 14. A slider 17 is provided at the top of the sprayer 16. The sprayer 16 and the cover plate 12 form a rotating structure through the rotating rod 14, and the rotating rod 14 and the cover plate 12 are movably connected. The sprayer 16 forms a sliding structure through the slider 17 and the sliding groove 15, and the slider 17 and the sliding groove 15 are connected to the cover plate 12. When the device is in use, the stepper motor 13 is started, and the output shaft of the stepper motor 13 drives the rotating rod 14 to rotate. Driven by the rotation of the rotating rod 14, the sprayer 16 is driven to rotate counterclockwise along the slide groove 15 using the slider 17. The clockwise rotation of the rotating rod 6 forms a reverse motion. While the placement frame 9 rotates clockwise, it is directly scourted by the counterclockwise rotating sprayer 16. The increase in relative speed enhances the shearing force of the droplets on the oil stains, accelerates the peeling of surface dirt, and significantly improves the scouring force of the cleaning fluid on the dead corners of the bearing, achieving efficient cleaning of precision parts.

[0019] Working principle: In use, first move the device to a suitable position, then insert the bearing into the lead screw 10 on the placement rack 9, then rotate the fixing handle 11 to fix it onto the lead screw 10, limiting the bearing within a certain range. Next, insert the rotating rod 6 into the transmission rod 3, then rotate the nut 5 onto the transmission rod 3 to fix the rotating rod 6. Then pour in the cleaning solution, close the cover plate 12, and start the drive motor 2. The output shaft of the drive motor 2 drives the transmission rod 3 to rotate. Since the transmission rod 3 and the rotating rod 6 are connected, they synchronously drive the stirring rod 8 on the rotating rod 6 and the placement rack 9 to rotate synchronously, promoting the cleaning solution to... A circulating convection is formed inside the tank, with fresh cleaning fluid continuously replenishing the bearing surface. Waste liquid that carries away dirt is quickly discharged or filtered. Then, the sprayer 16 is activated to spray, followed by the stepper motor 13. The output shaft of the stepper motor 13 drives the rotating rod 14 to rotate. Driven by the rotation of the rotating rod 14, the sprayer 16 is driven to rotate in the opposite direction to the rotating rod 6 by the slider 17 along the slide groove 15. This creates a counter-current convection with the rotation of the bearing driven by the rotating rod 6, accelerating the removal of dirt from the surface. This completes the process of using the device. Any content not described in detail in this specification is prior art known to those skilled in the art.
