Description
Technical Field
[0001] This utility model relates to the field of bearing cover cleaning technology, and in particular to an automatic bearing cover cleaning device. Background Technology
[0002] Bearing caps are mechanical parts used to fix bearings, protect the internal structure of bearings, and bear part of the load. They are usually installed on the outer ring of the bearing or above the bearing housing. They are commonly found in rotating machinery such as motors and automotive gearboxes, and play an important role in the stable operation of the equipment.
[0003] An automatic bearing cover cleaning device is a device that uses mechanical transmission and spray (or ultrasonic, etc.) cleaning technology to automatically clean the surface and crevices of the bearing cover. It can realize the integrated operation of feeding, cleaning and draining processes, and has the characteristics of high efficiency, high cleanliness and reduced manual intervention. It is suitable for bearing production and maintenance scenarios.
[0004] In the existing technology, some automatic bearing cover cleaning devices use simple clamps to fix the bearing cover. Since bearing covers come in various shapes and sizes, simple clamps are difficult to adapt to different types of bearing covers, resulting in poor fixing effect. During the cleaning process, the bearing cover is prone to shaking or even falling off, which can damage the cleaning equipment. Therefore, an automatic bearing cover cleaning device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automatic bearing cover cleaning device, which aims to improve the problem of bearing cover shaking or even falling off in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic bearing cover cleaning device includes a housing, a conveyor belt inside the housing, multiple fixed boxes on the top of the conveyor belt, a pressure ring slidably connected inside the fixed box, two driving blocks fixedly connected to the inner wall of the pressure ring, a positioning post fixedly connected to the inner wall of the fixed box, two driven grooves inside the positioning post, a spring 1 fixedly connected to the top inner wall of the driven groove, two rotating plates rotatably connected to the inner wall of the positioning post, driven blocks fixedly connected to the bottom of the two rotating plates on their far sides, a spring 2 fixedly connected to the two rotating plates on their near sides, clamping blocks fixedly connected to the top of the two rotating plates on their far sides, and two cleaning components rotatably connected inside the housing.

[0009] The cleaning assembly includes a rotating roller, a motor is fixedly connected to the right side of the housing, multiple nozzles are rotatably connected to the inner wall of the housing, multiple fixing rings are fixedly connected to the outside of the rotating roller, and multiple connecting grooves are opened inside the fixing rings.
[0010] As a further description of the above technical solution:
[0011] A spring three is fixedly connected to the bottom inner wall of one of the connecting grooves, a support block is fixedly connected to the top of the spring three, a brush is fixedly connected to the top of the support block, a return pipe is fixedly connected to the right side of the housing, and a collection box is provided on the right side of the housing.
[0012] As a further description of the above technical solution:
[0013] The active block is externally slidably connected to the inside of the driven slot, and the bottom of the active block and the top of the driven block are in contact.
[0014] As a further description of the above technical solution:
[0015] The support block is externally slidably connected to the inside of the connecting groove, and the right side of one of the rotating rollers is fixedly connected to the drive end of the motor.
[0016] As a further description of the above technical solution:
[0017] The rear side of the return pipe is fixedly connected to the front side of the collection box, and a control meter is fixedly connected to the housing.

[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, by placing the bearing cover inside the fixed box, the weight of the bearing cover presses the pressure ring, and the pressure ring slides down along the inner wall of the positioning post and drives the active block to move down synchronously. Then, the active block presses the driven block, forcing the rotating plate to overcome the elastic force of the second spring and rotate around the inner wall of the positioning post. At this time, the clamping block moves towards the edge of the bearing cover's axis. The first spring is stretched when the active block slides down. When the bearing cover is removed, the first spring rebounds and resets the pressure ring. Thus, the mechanical transmission is triggered by the weight of the bearing cover without additional drive. The clamping block can automatically fit the edge of bearing covers of different specifications and cooperate with the positioning post to achieve axis calibration, ensuring fixing accuracy and versatility.
[0024] 2. In this utility model, the starting motor drives one of the rotating rollers to rotate, and the belt drive drives the other rotating roller to rotate synchronously. The fixed ring outside the rotating roller rotates accordingly, so that the brush performs mechanical friction cleaning on the surface of the bearing cover. At the same time, the nozzles distributed at multiple angles spray high-pressure cleaning liquid synchronously. The support block slides in the connecting groove and compresses the spring three, so that the brush elastically retracts. This achieves no dead angle coverage of all parts of the bearing cover, and can adapt to the cleaning of stubborn stains. While ensuring the cleaning effect, it avoids surface damage and greatly improves cleaning efficiency and quality. Attached Figure Description

Detailed Implementation
[0032] 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 creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an automatic bearing cover cleaning device, including a housing 1. The housing 1 provides installation space and protection for the internal device. A conveyor belt 2 is provided inside the housing 1. The conveyor belt 2 can transport and clean the bearing cover. Multiple fixing boxes 3 are provided on the top of the conveyor belt 2. The fixing boxes 3 can fix the bearing cover and prevent it from moving during cleaning. A pressure ring 4 is slidably connected inside the fixing box 3. When the bearing cover is placed, the pressure ring 4 can be squeezed and made to slide down. Two active blocks 5 are fixedly connected to the inner wall of the pressure ring 4. When the pressure ring 4 slides down, it can drive the active blocks 5 to slide down synchronously. A positioning post 6 is fixedly connected to the inner wall of the fixing box 3. The positioning post 6 can quickly position the bearing cover and place it at the center of the shaft when it is placed.
[0034] The positioning post 6 has two driven grooves 7 inside, which provide fixation and support for spring 8. Spring 8 is fixedly connected to the top inner wall of the driven groove 7. Spring 8 has an elastic function and provides elastic support for its driving block 5. When the driving block 5 slides down, it can stretch spring 8. Two rotating plates 9 are rotatably connected to the inner wall of the positioning post 6. The rotating plates 9 are squeezed by the driven block 10 and can rotate. The bottom of the two rotating plates 9 on the far side is fixedly connected to the driven block 10. When the driving block 5 slides down, it squeezes the driven block 10 and can rotate the two springs 11. The two rotating plates 9 on the near side is fixedly connected to the springs 11. Springs 11 have an elastic function and provide elastic support for the two rotating plates 9. The top of the two rotating plates 9 on the far side is fixedly connected to the clamping block 12. When the rotating plate 9 rotates, it drives the clamping block 12 above to move towards the axial edge of the bearing cover and fix the bearing cover. Two cleaning components are rotatably connected inside the housing 1.
[0035] Reference Figures 3 to 5The cleaning assembly includes a rotating roller 13, which provides fixation and support for an external fixed ring 16. The roller rotates by receiving force from a motor 14. The motor 14 is fixedly connected to the right side of the housing 1 and serves as the power source for the cleaning assembly. Multiple nozzles 15 are rotatably connected to the inner wall of the housing 1. The nozzles 15 are used to spray cleaning liquid onto the surface of the bearing cover. Multiple fixed rings 16 are fixedly connected to the outside of the rotating roller 13. The fixed rings 16 are used to receive force from the rotating roller 13 and rotate, thereby driving the brush 20 to rotate and clean. Multiple connecting grooves 17 are provided inside the fixed rings 16. The connecting grooves 17 provide fixation and support for the spring 18.
[0036] One of the connecting grooves 17 has a spring 18 fixedly connected to the bottom inner wall. The spring 18 has an elastic function and can provide elastic support for the support block 19 and the brush 20. The support block 19 is fixedly connected to the top of the spring 18. The support block 19 provides fixation and support for the brush 20. The brush 20 is fixedly connected to the top of the support block 19. The brush 20 can clean the surface of the bearing cover. A return pipe 21 is fixedly connected to the right side of the housing 1. The return pipe 21 can recycle the used cleaning liquid. A collection box 22 is provided on the right side of the housing 1. The collection box 22 can collect the used cleaning liquid for subsequent recycling.
[0037] Reference Figures 2 to 4 The active block 5 is externally slidably connected to the inside of the driven groove 7. The driven groove 7 provides a limiting and guiding function for the active block 5. The bottom of the active block 5 is in contact with the top of the driven block 10. The active block 5 can squeeze the driven block 10, causing its rotating plate 9 to rotate. The support block 19 is externally slidably connected to the inside of the connecting groove 17. The connecting groove 17 provides a limiting and guiding function for the support block 19. The right side of one of the rotating rollers 13 is fixedly connected to the drive end of the motor 14. The motor 14 drives one of the rotating rollers 13 to rotate, and then drives the other rotating roller 13 to rotate and clean through belt transmission.
[0038] The rear side of the return pipe 21 is fixedly connected to the front side of the collection box 22. The return pipe 21 can deliver the cleaning liquid to the inside of the collection box 22. The housing 1 is fixedly connected to the control gauge 23, which facilitates the operator to control the device. Multiple nozzles 15 can spray at different angles. The nozzles 15 spray at different angles, which can coat the surface of the bearing cover with cleaning liquid. Two rotating rollers 13 can prevent the cleaning from being difficult to do in one go. The two rotating rollers 13 can prevent the cleaning from being difficult to do in one go, thereby enhancing the cleaning effect. The brush 20 is pressed against the spring 3 18 by the impact force. When the brush 20 encounters impurities that are difficult to clean in one go, it retracts due to the elastic action of the spring 3 18. The two rotating rollers 13 are externally rotatably connected to the inner wall of the housing 1. The housing 1 can provide support for the rotating rollers 13.
[0039] Working principle: During use, the bearing cover is placed in the fixed box 3. The weight of the bearing cover compresses the pressure ring 4. The pressure ring 4 slides down along the inner wall of the positioning post 6 and drives the active block 5 to move down synchronously. Then, the active block 5 compresses the driven block 10, forcing the rotating plate 9 to overcome the elastic force of the second spring 11 and rotate around the inner wall of the positioning post 6. At this time, the clamping block 12 moves towards the edge of the bearing cover shaft until it fits tightly with the bearing cover. The first spring 8 is stretched when the active block 5 slides down. When the bearing cover is removed, the first spring 8 rebounds and resets the pressure ring 4. This process achieves rapid and accurate positioning and fixing of the bearing cover through mechanical linkage, ensuring that no displacement occurs during the cleaning process.
[0040] When the bearing cover needs cleaning, the motor 14 is started to drive one of the rotating rollers 13 to rotate, and the other rotating roller 13 is driven to rotate synchronously through the belt drive. The fixing ring 16 on the outside of the rotating roller 13 rotates accordingly, so that the brush 20 performs mechanical friction cleaning on the surface of the bearing cover. At the same time, the nozzles 15 distributed at multiple angles spray high-pressure cleaning liquid synchronously, covering the top, sides and gaps of the bearing cover. When the brush 20 comes into contact with stubborn stains, the support block 19 slides in the connecting groove 17 and compresses the spring 3 18, so that the brush 20 elastically retracts, avoiding hard scratching of the bearing cover surface, while increasing the contact pressure to enhance the cleaning effect. The brushes 20 on the two rotating rollers 13 work alternately to achieve the synergistic effect of the initial cleaning and secondary fine cleaning. The waste liquid after cleaning is guided through the bottom of the housing 1 to the return pipe 21, and finally flows into the collection box 22 for filtration and recycling.
[0041] 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.
