Description

Technical Field

[0001] This application belongs to the technical field of bearing production equipment, specifically a multi-stage bearing cleaning device. Background Technology

[0002] Bearings are common components in mechanical equipment, serving to reduce resistance between two rotating parts and extend their service life. For bearings, especially precision bearings, internal impurities can lead to quality problems such as wear on the bearing rings and rolling elements, and excessive operating noise. Therefore, bearing manufacturers need to clean bearings during production to remove metal shavings, oil, dust, and other impurities from the inside and surface of the bearing.

[0003] Currently, most bearing manufacturers use ultrasonic cleaners for bearing cleaning, which automatically transport bearings via a metal conveyor belt for cleaning. However, this method, where the bearing remains in one position on the conveyor belt, results in incomplete cleaning. To improve cleaning efficiency, existing technologies often involve making the cleaner longer, extending the cleaning time. However, this improvement still leaves blind spots in the cleaning process, leading to unsatisfactory cleaning results. Utility Model Content

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0024] Please refer to the following: Figures 1 to 8 The bearing multi-stage cleaning device provided in the embodiments of this application will be described below.

[0025] Please see Figure 1 and Figure 2 The multi-stage bearing cleaning device provided in this application embodiment is suitable for cleaning finished bearings, bearing rings, bearing housings, and other components. The device includes a cleaning unit 10, a drying unit 20, a flipping unit 30, and a transfer unit 40. These multiple units can be automated through PLC program control, and automatic loading and unloading can be achieved using existing material conveying equipment such as conveyor belts. Both PLC control and automated material conveying via conveyor belts are common control methods and loading / unloading forms in the bearing manufacturing field; their specific composition and working principles will not be elaborated further.

[0026] The cleaning unit 10 is used to rinse the bearing with high-pressure water. Two or more cleaning units 10 are provided, and the multiple cleaning units 10 are spaced apart along the bearing conveying direction to achieve multi-stage cleaning of the bearing. The multiple cleaning units 10 work together with the flipping unit 30 to flip the bearing to improve the cleaning effect.

[0027] The cleaning unit 10 specifically includes a first drain plate 11, a cleaning nozzle 12, a first splash guard 13, and a first lifting mechanism 14. The first drain plate 11 is horizontally arranged and has mesh holes to allow cleaning fluid to leak down. The first splash guard 13 is located above the first drain plate 11, and the cleaning nozzle 12 is located at the top of the inner cavity of the first splash guard 13. The first lifting mechanism 14 is used to drive the first splash guard 13 to move up and down. During cleaning, the first lifting mechanism 14 first drives the first splash guard 13 to descend, so that the lower end of the first splash guard 13 abuts against the upper surface of the first drain plate 11, forming a closed space. Finally, the cleaning nozzle 12 sprays high-pressure cleaning fluid to rinse the bearing. The sprayed rinsing fluid leaks downward from the first drain plate 11. After cleaning, the first lifting mechanism 14 drives the first splash guard 13 to rise, and the transfer unit 40 transfers the bearing to the next work station.

[0028] The first lifting mechanism 14 and the second lifting mechanism 24 mentioned below can be existing lifting drive components such as lifting cylinders and electric lifting rods, and are connected to the corresponding air source or power source through necessary valves, pipelines, cables, etc. Their structure and connection methods are all existing technologies, and will not be described in detail here.

[0029] The cleaning nozzle 12 can be any commercially available liquid nozzle that can generate a water flow that impacts the bearing surface. To prevent the cleaning fluid from splashing, a first splash guard 13 is placed over the first drain plate 11 during cleaning. The first splash guard 13 also prevents the bearing from moving extensively during the cleaning fluid flushing process.

[0030] As needed, the upper surface of the first drain plate 11 can be provided with a structure for limiting the bearing, thereby effectively preventing the bearing from moving when impacted by the cleaning fluid. The limiting structure can be an existing bearing holding or adsorption structure such as a locking block or a magnetic chuck.

[0031] There are no restrictions on the pressure, flow rate, and other parameters of the cleaning fluid sprayed from the cleaning nozzle 12 during bearing cleaning. The rinsing pressure of the two cleaning units 10 set before and after the bearing is rotated can be the same or different, as long as the expected cleaning effect can be achieved.

[0032] The cleaning nozzle 12 is connected to the cleaning fluid supply source via connectors and valves. Once the valve is activated, the fluid path is open, and the cleaning fluid reaches the cleaning nozzle 12 through the pipe connector. The cleaning nozzle 12 then flushes the bearing. After flushing, the valve is closed, and the cleaning nozzle 12 stops spraying cleaning fluid. The connectors and valves mentioned above are all existing technologies, and their specific specifications, models, and installation methods are not specifically limited.

[0033] At least one drying unit 20 is provided for blowing air onto the bearing to dry its surface. The drying unit 20 is located behind the cleaning unit 10 at the end of the bearing conveying process. The drying unit 20 includes a second drain plate 21, a drying nozzle 22, a second splash guard 23, and a second lifting mechanism 24. The second drain plate 21 is horizontally arranged, the second splash guard 23 is located above the second drain plate 21, the drying nozzle 22 is located at the top of the inner cavity of the second splash guard 23, the drying nozzle 22 is connected to an air source, and the second lifting mechanism 24 is used to drive the second splash guard 23 to move up and down.

[0034] The air-drying nozzle 22 is connected to an air source and can blow hot or room temperature air to dry the bearing surface within a specified time. The second drain plate 21 is used to drip off any residual cleaning fluid on the bearing surface. The structure of the second drain plate 21 can be the same as that of the first drain plate 11, and the structure of the second splash guard 23 can be the same as that of the first splash guard 13.

[0035] Please see Figure 1 and Figure 2When two drying units 20 are provided, the two drying units 20 are spaced apart along the bearing conveying direction, and a flipping unit 30 is provided between the two drying units 20, resulting in better drying effect. After the drying units 20 are conveyed, they can be transported to the testing process by the bearing conveying equipment. The testing equipment tests parameters such as bearing clearance, and packaging is carried out after they pass the test.

[0036] The air-drying nozzle 22 is connected to the air source through an air connector, a gas delivery pipe, and a solenoid valve to control the opening and closing of the gas pipeline.

[0037] The flipping unit 30 is used to flip the bearing so that the bottom and top surfaces of the bearing are reversed. A flipping unit 30 should be provided between two cleaning units 10. In addition, when multiple drying units 20 are provided, a flipping unit 30 should also be provided between two drying units 20.

[0038] Multiple transfer units 40 are movably disposed between the corresponding cleaning unit 10 and flipping unit 30, and between the drying unit 20 and cleaning unit 10, respectively, for transferring the bearing along the bearing conveying direction, so that the bearing passes through the working positions of different units in sequence, and the bearing is sequentially cleaned, flipped, finely cleaned, dried, flipped, and dried again.

[0039] The specific shape and structure of the flipping unit 30 and the transfer unit 40 are not limited, and they can be components such as robotic arms that can clamp and move bearings in the prior art.

[0040] It is understandable that multiple units such as the cleaning unit 10, drying unit 20, flipping unit 30, and transfer unit 40 can be automated through PLC program control, and automatic loading and unloading can be achieved through existing material conveying equipment such as conveyor belts. Both the PLC control method and the automated material conveying method of conveyor belts are common control methods and loading and unloading forms in the bearing manufacturing industry, and their specific composition and working principle will not be elaborated further.

[0041] Compared with the prior art, the beneficial effects of the bearing multi-stage cleaning device provided in this application are: The multi-stage bearing cleaning device provided in this application includes a cleaning unit 10, a drying unit 20, a flipping unit 30, and a transfer unit 40. Multiple cleaning units 10 are provided, and a flipping unit 30 is provided between adjacent cleaning units 10. The transfer unit 40 is used to sequentially transport the bearing through the working positions of the multiple units along the conveying direction. During operation, the bearing first arrives at the cleaning unit 10 located at the front end of the conveyor. A first drain plate 11 supports the bearing. A first lifting mechanism 14 drives a first splash guard 13 downwards to abut against the first drain plate 11, and a cleaning nozzle 12 sprays cleaning fluid to rinse the bearing. After cleaning, the bearing is transferred to the flipping unit 30, which flips the bearing up and down. Then, the transfer unit 40 transfers it to the working position of the next cleaning unit 10, repeating the above actions to rinse the other side of the bearing. Finally, the bearing is transferred to the second drain plate 21, a second lifting mechanism 24 drives a second splash guard 23 to descend, and a drying nozzle 22 blows away any remaining cleaning fluid from the bearing surface.

[0042] In this embodiment, the bearing is flipped using a flipping unit 30, and two cleaning units 10 clean the bearing before and after the flipping, respectively. The flipping unit 30 and the two cleaning units 10 work together to help eliminate blind spots in the cleaning process and improve the cleaning effect. After cleaning, the bearing is air-dried using a drying unit 20 to prevent residual cleaning fluid on the bearing surface from affecting subsequent processes.

[0043] It should be noted that the working cycle of the cleaning unit 10, the drying unit 20, and the flipping unit 30 should be consistent in order to achieve synchronous transfer of multiple bearings between the above-mentioned unit stations.

[0044] Specifically, while the cleaning unit 10 is cleaning one bearing, the drying unit 20 is simultaneously drying the other bearing. After the cleaning unit 10 finishes its work, the drying unit 20 also stops blowing air. Multiple transfer units 40 operate synchronously, enabling multiple bearings to be transferred to different workstations at the same time, thereby realizing an automated production line mode for bearing cleaning and drying.

[0045] Please see Figure 1 and Figure 2 The first drain plate 21 and the first drain plate 11 can be circular or other shaped plates. Both the first drain plate 11 and the second drain plate 21 have drain holes penetrating their own thickness. These drain holes can be circular or other shaped holes, and multiple drain holes are evenly distributed. A liquid storage tank is located below the first drain plate 11 and the second drain plate 21. The cleaning fluid leaking through the drain holes falls into the liquid storage tank, which is used to store the cleaning fluid.

[0046] In order to achieve the circulation and transportation of cleaning fluid, the cleaning unit 10 also includes a pumping mechanism, which is a power pump capable of transporting cleaning fluid. The inlet end of the power pump is connected to the storage tank, and the outlet end of the pumping mechanism is connected to the cleaning nozzle 12 through a liquid transportation pipeline, pipe joint and necessary pipeline valves, so that cleaning fluid with appropriate liquid pressure and flow rate can be sprayed out through the cleaning nozzle 12 when needed.

[0047] Understandably, to prevent impurities such as metal shavings from being drawn up by the pumping mechanism, the cleaning fluid should pass through a filtration device or be drawn up by the pumping mechanism again. Existing products capable of filtering impurities from the cleaning fluid can be used as filtration devices, and their specific structural type is not limited.

[0048] To improve the spray cleaning effect on the bearing, multiple cleaning nozzles 12 are arranged at intervals along the circumference of the first splash guard 13. Multiple cleaning nozzles 12 spray cleaning fluid at the same time, which helps to eliminate cleaning dead corners and improve the cleaning effect.

[0049] To accelerate the drying speed of the bearing surface, the drying unit 20 also includes an air supply mechanism, which is a hot air blower. The air outlet of the hot air blower is connected to the drying nozzle 22, and the hot air blower forms the air source. The hot air blower can be a product currently available on the market, and there are no restrictions on the operating temperature of the hot air blower, such as 50-80℃.

[0050] To further improve the bearing drying speed, the drying unit 20 also includes a rotary drive component. The output shaft of the rotary drive component is connected to the second drain plate 21 for driving the second drain plate 21 to rotate around its own vertical axis. The rotary drive component can be a motor, and the output shaft of the motor is connected to the vertical rotation axis of the second drain plate 21 through common transmission structures such as gear transmission and chain transmission. This enables the second drain plate to rotate at high speed around the vertical axis, thus drying the cleaning fluid.

[0051] During drying, the second drain plate 21 can be rotated by a rotary drive, which in turn rotates the bearing above it, using centrifugal force to spin-dry the cleaning fluid. The drying speed of the cleaning fluid is faster due to the hot air blown from the drying nozzle 22 and the centrifugal action of the rotary drive and the second drain plate 21 on the bearing.

[0052] Please see Figure 7 To prevent the bearing from being thrown off by centrifugal force when the second leak plate 21 rotates, a pressure rod 231 is provided at the top of the inner cavity of the second splash guard 23. The pressure rod 231 is vertically arranged, with its upper part rotatably connected to the second splash guard 23 and its lower part used to abut against the bearing to be air-dried. Under the clamping of the upper pressure rod 231 and the lower second leak plate 21, the bearing will not be thrown off by centrifugal force.

[0053] To avoid the pressure rod 231 being too large and affecting the drying effect of the bearing, the lower end of the pressure rod 231 is provided with multiple pressing parts 232 at intervals along its circumference. The pressing parts 232 are used to abut against the outer ring or inner ring of the bearing, and the contact area between the pressing parts 232 and the bearing is small.

[0054] Please see Figures 1 to 7 Each cleaning unit 10 includes multiple first drain plates 11 and multiple first splash guards 13. The upper surface of each first drain plate 11 is used to support a bearing. The first splash guard 13 is located above the corresponding first drain plate 11. The lifting end of the first lifting mechanism 14 is connected to multiple first splash guards 13 simultaneously through connecting rods, connecting plates and other components.

[0055] The first splash guard 13 and the second splash guard 23 can be metal or plastic. When a metal guard is used, a transparent observation window can be provided on the top to allow operators to observe the condition of the bearings inside from the outside.

[0056] Please see Figure 8 The flipping unit 30 includes a pressure plate 31, a two-way cylinder 32, and a rotary motor 33. The two pressure plates 31 are arranged opposite each other, and the two telescopic ends of the two-way cylinder 32 are respectively connected to the two pressure plates 31. The lower pressure plate 31 is used to support the bearing, and the rotary motor 33 is connected to the two-way cylinder 32.

[0057] When the bearing needs to be flipped, the transfer unit 40 transfers the cleaned bearing to the pressure plate 31 located below. The two-way cylinder 32 drives the two pressure plates 31 to move closer together and clamp the bearing. Then, the rotary motor 33 drives the two-way cylinder 32 to rotate around the horizontal axis, achieving a 180-degree flip. After the flip is completed, the two-way cylinder 32 drives the two pressure plates 31 to separate, and the transfer unit 40 transfers the flipped bearing axially to the next station.

[0058] Please see Figures 1 to 5 The transfer unit 40 includes a clamping mechanism 41 and a traversing mechanism 42. The clamping mechanism 41 includes two clamping plates 411 arranged opposite each other, and a telescopic rod 412 for driving the two clamping plates 411 closer together or further apart. The telescopic rod 412 can be a bidirectional telescopic cylinder with two telescopic ends, or two independent electric telescopic components. Both bidirectional telescopic cylinders and electric telescopic components are existing telescopic drive components. A clamping space for accommodating the bearing is formed between the two clamping plates 411. When the two clamping plates 411 are close together, the bearing is clamped; when the two clamping plates 411 are far apart, the bearing is released.

[0059] The traverse mechanism 42 is used to drive the clamping mechanism 41 to move along the bearing conveying direction. The traverse mechanism 42 can be an electric telescopic rod, telescopic cylinder, etc., arranged along the bearing conveying direction. The traverse mechanism 42 is used to drive the clamping mechanism 41 to move between two adjacent workstations.

[0060] The two clamping plates 411 used to hold the bearing are defined as a left clamping plate and a right clamping plate. When each cleaning unit 10 includes two first leakage plates 11, two sets of clamping plates 411 should be provided accordingly, that is, two left clamping plates and two right clamping plates are provided respectively. To simplify the structure, the two left clamping plates can be connected to the same telescopic rod 412 via a crossbar, and the two right clamping plates can be connected to another telescopic rod 412 via a crossbar. That is, the telescopic rod 412 can be moved by driving either the two left clamping plates or the right clamping plates.

[0061] like Figure 3 As shown, a retraction mechanism 43 can also be provided as needed. The retraction mechanism 43 is connected to the clamping mechanism 41, and the lateral movement mechanism 42 drives the retraction mechanism 43 to move along the bearing conveying direction. The retraction mechanism 43 is an electric telescopic rod or a telescopic cylinder, which can drive the clamping mechanism 41 to move in a horizontal direction perpendicular to the bearing conveying direction, so that the clamping plate 411 is removed from the coverage of the first splash shield 13 or the second splash shield 23, and avoids the clamping plate 411 from affecting the descent of the first splash shield 13 or the second splash shield 23.

[0062] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
