Description

Technical Field

[0001] The invention relates to the technical field of bearing rings, and in particular to a high-cleanliness automatic cleaning device for bearing rings. Background Art

[0002] Thin-walled bearings are a special type of deep groove ball bearings, suitable for equipment with high speed, high precision and high environmental requirements, such as aerospace, robotics, automation equipment, etc. Thin-walled bearings are widely used in various industries due to their lightweight and high reliability, and with the continuous development of technology, the thin-walled bearing industry is also evolving and growing.

[0003] At present, most of the high-precision bearings used in domestic high-precision equipment are imported. With the increase of international influence, the game between major countries has become more frequent. In order to prevent being stuck in key areas, domestic substitution must be carried out in high-precision and cutting-edge technology fields. Bearings are key components widely used in all walks of life. The current production technology for high-precision bearings is far behind the advanced level. In particular, thin-walled bearings in high-speed and high-precision equipment have very high requirements for size and geometry, which requires enterprises to have advanced precision manufacturing technology through continuous technical improvements. Thin-walled bearings are mainly 67, 68, and 69 series products. The main characteristics of these products are thin wall thickness, large products, and narrow widths, which make it easy to accumulate dust, difficult to clean, and the cleanliness of the rings is not high.

[0004] At the same time, the existing cleaning products use a channel structure for bearing rings. The main working principle is: the rings are pushed to the demagnetization area by the belt push rod, and then pushed to the track by the cleaning push rod. The product is powered by the cleaning push rod and moves in the same direction, undergoing ultrasonic cleaning, nozzle cleaning, and finally drying to enter the next process. The main disadvantages are as follows:

[0005] 1. Since the product is powered by mutual squeezing, it will cause the product to deform.

[0006] 2. The product is large and thick, and the channel is wide, so it is not easy to clean the product with the cleaning nozzle.

[0007] 3. The product is large and thick, so it takes a long time to spin dry. When the speed is high, there is a risk of the product flying away.

[0008] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0009] In view of the problems in the related art, the present invention proposes a high-cleanliness automatic cleaning device for a bearing ring to overcome the above-mentioned technical problems existing in the existing related art.

[0010] The technical solution of the present invention is achieved in this way:

[0011] A high-cleanliness automatic cleaning device for a bearing ring comprises: a conveyor belt for conveying materials for the bearing ring and a material shifting mechanism arranged on one side of the conveyor belt for shifting materials for the bearing ring, wherein one side of the conveyor belt is provided with a first cleaning mechanism for cleaning the front side of the bearing ring, a second cleaning mechanism for cleaning the back side of the bearing ring, a first drying mechanism for drying the front side of the bearing ring and a second drying mechanism for drying the back side of the bearing ring in sequence, a first flipping mechanism for flipping the bearing ring is provided between the first cleaning mechanism and the second cleaning mechanism, and a second flipping mechanism is provided between the first drying mechanism and the second drying mechanism.

[0012] The first cleaning mechanism, the second cleaning mechanism, the first drying mechanism, the second drying mechanism, the first turning mechanism and the second turning mechanism are respectively adapted to the material moving mechanism.

[0014] Furthermore, the guide rail is sleeved with a spring located between the loading plate and the bearing plate.

[0015] Furthermore, a plurality of drainage ports are provided in the material plate, and a belt pulley is sleeved on the bottom end of the material plate, and the belt pulley is connected to an output end of a rotating motor provided on one side of the bearing plate through a transmission belt.

[0016] Furthermore, the first cleaning mechanism and the second cleaning mechanism further include: a cleaning cover adapted to the material trough is provided at the bottom end of the loading plate, and a nozzle is provided in the cleaning cover.

[0017] Furthermore, the first drying mechanism and the second drying mechanism further include: a drying cover adapted to the material trough is provided at the bottom end of the loading plate, and a dryer is provided in the drying cover.

[0018] Furthermore, the first flipping mechanism and the second flipping mechanism respectively include: a flipping motor arranged between the supporting plates, and a clamping plate is arranged at the output end of the flipping motor.

[0019] Furthermore, the material moving mechanism comprises a slide rail arranged on one side of the bearing plate, and a fixture adapted to the bearing ring is arranged in the slide rail.

[0020] Beneficial effects of the present invention:

[0021] The present invention moves the bearing ring to the material trough of the first cleaning mechanism in advance through the conveyor belt and the material shifting mechanism, and adjusts the loading plate in the vertical direction along the guide rail through the telescopic motor drive, so that the cleaning cover extends into the material trough to cover the material plate, and at the same time, the rotating motor cooperates with the transmission belt and the pulley to link the material trough to rotate, so that the nozzle in the cleaning cover cleans the rotating bearing ring on the material trough; and after cleaning, the bearing ring cleaned on the front side is shifted to the first flipping mechanism for flipping through the material shifting mechanism, and shifted to the second cleaning mechanism for back side cleaning, and after cleaning, the material shifting mechanism is shifted to the first drying mechanism for front side drying through the drying cover and the dryer, and is shifted to the second drying mechanism for back side drying through the drying cover and the dryer, so that the bearing ring is automatically cleaned with high cleanliness. Washing and drying, through independent material troughs and material plates, deformation of the bearing rings due to mutual squeezing is avoided, and a cleaning hood is extended into the material trough to cover the material plate, which improves the cleanliness of the bearing ring groove and prevents splashing of the cleaning liquid. The rotating motor cooperates with the transmission belt and the pulley to link the material trough to rotate, which can solve the pain point that the product is large and the cleaning liquid cannot rotate it, thus the groove is not cleaned cleanly, and the overall cleanliness of the bearing ring is greatly improved. At the same time, the cleaning process is in a relatively closed environment, and there is no risk of product falling. In addition, the first drying mechanism and the second drying mechanism are used for full and independent drying, which avoids the bearing ring from being defective due to excessive humidity to the greatest extent, further improving product quality and enhancing product reliability.

In addition, there is no need for excessive manual intervention, which greatly reduces manual operation time and labor intensity, and improves production efficiency.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0029] According to an embodiment of the present invention, a bearing ring automatic cleaning device with high cleanliness is provided.

[0031] A first turning mechanism 5 for turning over the bearing ring is provided between the first cleaning mechanism 1 and the second cleaning mechanism 2, and a second turning mechanism 6 is provided between the first drying mechanism 3 and the second drying mechanism 4.

[0032] The first cleaning mechanism 1 , the second cleaning mechanism 2 , the first drying mechanism 3 , the second drying mechanism 4 , the first turning mechanism 5 and the second turning mechanism 6 are respectively matched with the material moving mechanism 8 .

[0033] In addition, the first cleaning mechanism 1, the second cleaning mechanism 2, the first drying mechanism 3 and the second drying mechanism 4 respectively include a supporting plate 9 adapted to the material moving mechanism 8, a plurality of material troughs 10 are arranged in the supporting plate 9, adjacent material troughs 10 are provided with spacing, and a material plate 11 is movably arranged in the material trough 10, and a symmetrically arranged guide rail 12 is provided on one side of the supporting plate 9, a loading plate 13 is sleeved on the guide rail 12, a telescopic motor 15 is provided at the top end of the guide rail 12, and the output end of the telescopic motor 15 is fixedly connected to the loading plate 13.

[0034] The guide rail 12 is provided with a spring 16 between the loading plate 13 and the bearing plate 9 .

[0035] The first cleaning mechanism 1 and the second cleaning mechanism 2 further include: a cleaning cover 14 adapted to the material tank 10 is provided at the bottom of the loading plate 13 , and a nozzle is provided in the cleaning cover 14 .

[0036] In the application of the present technical solution, the material trough 10 can adopt a multi-material trough 10 design, which is convenient for improving the loading capacity and adapting to the batch cleaning of the enterprise. The adjacent material troughs 10 adopt a separate design to avoid mutual interference between the material plates 11 of the adjacent material troughs 10 and avoid deformation of the bearing rings due to mutual squeezing.

[0037] At the same time, the loading plate 13 is driven by the telescopic motor 15 to adjust vertically along the guide rail 12, so that the cleaning cover 14 extends into the material trough 10 to cover the material plate 11, and the spring 16 can be used to assist in resetting the loading plate 13, so that the cleaning process is in a relatively closed environment, there is no risk of product falling, and splashing of cleaning liquid is prevented.

[0038] In addition, a plurality of drainage ports 17 are provided in the material plate 11 , and a pulley 18 is sleeved on the bottom end of the material plate 11 . The pulley 18 is connected to the output end of a rotating motor 20 provided on one side of the bearing plate 9 through a transmission belt 19 .

[0039] In the present technical solution, the drain outlet 17 can uniformly recycle the cleaning waste water and residual liquid through the bottom of the supporting plate 9 during the cleaning process or the drying process, and the rotating motor 20 cooperates with the transmission belt 19 and the pulley 18 to rotate the material trough 10, which can solve the problem that the product is large and the cleaning liquid cannot rotate it, thereby the pain point of unclean channel cleaning, and the overall cleanliness of the bearing ring is greatly improved.

[0040] In addition, the first drying mechanism 3 and the second drying mechanism 4 further include: a drying cover 24 adapted to the material trough 10 is provided at the bottom of the loading plate 13 , and a dryer is provided in the drying cover 24 .

[0041] The technical solution uses a drying hood 24 that is adjusted in the vertical direction to independently dry the front and back sides of the cleaned bearing rings, and has good drying uniformity, avoiding uneven local drying, ensuring consistent drying effects for the entire ring, and being able to ensure that the bearing rings reach the degree of dryness required for high cleanliness, effectively removing moisture from the surface and interior, preventing rust, corrosion and other problems caused by residual moisture, and improving the quality and service life of the bearing rings.

[0042] In addition, the first turning mechanism 5 and the second turning mechanism 6 respectively include a turning motor 21 disposed between the carrying plates 9 , and a clamping plate 22 is disposed at the output end of the turning motor 21 .

[0043] Specifically, the first turning mechanism 5 or the second turning mechanism 6 is used to turn over the bearing ring, thereby facilitating subsequent cleaning or drying of the top surface of the bearing ring.

[0044] In addition, the material moving mechanism 8 includes a slide rail 23 arranged on one side of the bearing plate 9, and a fixture adapted to the bearing ring is arranged inside the slide rail 23.

[0045] In this technical solution, the fixture uses the bearing ring to move horizontally along the slide rail 23 to achieve the clamping and transfer of materials to the bearing ring.

[0046] With the aid of the above scheme, the bearing ring is moved to the material trough 10 of the first cleaning mechanism 1 in advance through the conveyor belt 7 and the material shifting mechanism 8, and the loading plate 13 is driven by the telescopic motor 15 to adjust the vertical direction along the guide rail 12, so that the cleaning cover 14 extends into the material trough 10 to cover the material plate 11, and at the same time, the rotating motor 20 cooperates with the transmission belt 19 and the pulley 18 to rotate the material trough 10, so that the nozzle in the cleaning cover 14 cleans the rotating bearing ring on the material trough 10; and after cleaning, the bearing ring cleaned on the front side is shifted to the first flipping mechanism 5 for flipping through the material shifting mechanism 8, and shifted to the second cleaning mechanism 2 for back side cleaning, and after cleaning, it is shifted to the first drying mechanism 3 through the material shifting mechanism 8 to cooperate with the drying cover 24 and the dryer for front side drying, and shifted to the second drying mechanism 4 to cooperate with the drying cover 24 and the dryer for back side drying.

[0047] The bearing ring is automatically cleaned and dried with high cleanliness. The deformation of the bearing ring caused by mutual squeezing is avoided by the independent material trough 10 and material plate 11. The cleaning cover 14 is extended into the material trough 10 to cover the material plate 11, which improves the cleanliness of the bearing ring channel and prevents the splashing of the cleaning liquid. The rotating motor 20 cooperates with the transmission belt 19 and the pulley 18 to rotate the material trough 10, which can solve the problem that the product is large and the cleaning liquid cannot rotate it, so that the channel is not cleaned properly. The overall cleanliness of the bearing ring is greatly improved. At the same time, the cleaning process is in a relatively closed environment, and there is no risk of product falling. In addition, the first drying mechanism 3 and the second drying mechanism 4 are used for full and independent drying, which avoids the bearing ring from being defective due to excessive humidity to the greatest extent, further improving product quality and enhancing product reliability.

[0048] In summary, with the help of the above technical solution of the present invention, the following effects can be achieved:

[0049] The present invention has high cleanliness and no dead angle in cleaning, can effectively remove oil, impurities, rust and the like on the surface and gaps of the bearing ring, realizes all-round cleaning of the inner and outer surfaces, teeth, crevices and other complex parts of the bearing ring, avoids the cleaning blind spots existing in traditional cleaning methods, ensures that the entire ring can be thoroughly cleaned, makes the bearing ring reach a higher cleanliness standard, and improves product quality; at the same time, ensures the consistency and stability of the cleaning effect, makes each bearing ring obtain the same quality of cleaning, is beneficial to improve the overall quality of the product and the stability of performance, in addition, does not require excessive manual intervention, greatly reduces manual operation time and labor intensity, and improves production efficiency.
