Technical Field

[0001] This application relates to the field of bearing ring processing equipment, and in particular to a bearing ring surface cleaning device. Background Technology

[0002] During the processing of bearing rings, a lot of steel chips, dust and other impurities will adhere to their surface. In order to ensure the cleanliness of the bearing rings, it is necessary to remove the impurities on the surface. Therefore, during the processing, a high-pressure nozzle is needed to spray cleaning fluid onto the surface of the bearing rings.

[0003] Utility Model Utility No. CN219965757U discloses a bearing ring cleaning machine. In this patent, to completely clean the surface of the bearing rings, a nozzle rotates circumferentially along the bearing ring, spraying cleaning fluid onto the entire surface, thereby removing impurities. In existing technologies, bearing ring cleaning relies solely on the impact force of the spray nozzle, resulting in low cleaning efficiency for the bearing ring surface. Utility Model Content

[0004] To address the issue that relying solely on the impact force of the nozzle for cleaning bearing races results in low cleaning efficiency of impurities on the bearing race surface, this application provides a bearing race surface cleaning device.

[0005] The bearing ring surface cleaning device provided in this application adopts the following technical solution:

[0006] A bearing race surface cleaning device includes a first rotating seat, a rotation fixing drive assembly, and a cleaning nozzle mounted on a worktable. The first rotating seat is rotatably mounted on the worktable, and the bearing race can be placed on the first rotating seat. The rotation fixing drive assembly can fix the bearing race on the first rotating seat and drive the bearing race to rotate. The cleaning nozzle is connected to a cleaning fluid supply system and can spray cleaning fluid onto the bearing race on the first rotating seat.

[0007] By adopting the above technical solution, when cleaning the bearing race, the bearing race is first placed on the first rotating seat, and then the rotating and fixing drive assembly presses and fixes the bearing race on the first rotating seat, and drives the bearing race to rotate. The cleaning nozzle sprays cleaning fluid onto the surface of the bearing race, so that the impurities on the surface of the bearing race are removed under the impact force of the cleaning fluid spray and the centrifugal force of the bearing race's rotation. Compared with the cleaning method that relies solely on the impact force of the cleaning fluid, this solution can speed up the cleaning of impurities on the surface of the bearing race and improve the cleaning efficiency.

[0008] Preferably, the rotary fixed drive assembly includes a linear drive mechanism, a rotary power component, and a pressure block. The linear drive mechanism is disposed on the worktable, the rotary power component is disposed on the linear drive mechanism, and the pressure block is disposed on the rotary power component. The linear drive mechanism can drive the pressure block to press down on the bearing ring to fix the bearing ring to the first rotating seat, and the rotary power component can drive the bearing ring to rotate.

[0009] By adopting the above technical solution, the linear drive mechanism can drive the pressure block to press down on the bearing ring, thereby fixing the bearing ring on the first rotating seat and ensuring the stability of the bearing ring during the cleaning process; the rotating power component can drive the bearing ring to rotate, so that the cleaning fluid is evenly sprayed on the surface of the bearing ring, improving the cleaning efficiency and cleaning effect.

[0010] Preferably, the rotating power component includes a first rotary motor and a first drive rod. The first drive rod is coaxially fixed on the output shaft of the first rotary motor, and the pressure block is slidably sleeved on the first drive rod and connected to the first drive rod through an elastic element.

[0011] By adopting the above technical solution, the pressure block is slidably sleeved on the first drive rod and connected by an elastic element, so that the pressure block has a certain buffering effect when fixing the bearing ring, avoiding damage to the bearing ring or equipment due to hard contact, while ensuring that the bearing ring is stable and does not shift during the cleaning process, thereby improving cleaning efficiency and cleaning quality.

[0012] Preferably, the elastic element includes a first telescopic spring, one end of which is connected to the first drive rod and the other end is connected to the pressure block, so as to press and fix the pressure block and the bearing ring together.

[0013] By adopting the above technical solution, the first telescopic spring can provide elastic force, so that the pressure block and the bearing ring maintain a stable pressing state, thereby improving the fixing effect of the bearing ring during the cleaning process.

[0014] Preferably, the cleaning fluid supply system includes a cleaning fluid storage tank and a delivery pump. The inlet end of the delivery pump is connected to the cleaning fluid storage tank, and the outlet end of the delivery pump is connected to the cleaning nozzle, so as to deliver the cleaning fluid in the cleaning fluid storage tank to the cleaning nozzle.

[0015] By adopting the above technical solution, the cooperation between the cleaning fluid storage tank and the delivery pump can achieve a stable supply of cleaning fluid, ensuring that the cleaning nozzle can continuously spray cleaning fluid onto the surface of the bearing ring, thereby improving cleaning efficiency.

[0016] Preferably, the cleaning fluid storage tank is equipped with a partition that separates the cleaning fluid storage tank into a first chamber and a second chamber. A collection cylinder is provided below the first rotating seat to collect the cleaning fluid after cleaning. The collection cylinder is connected to the second chamber through a pipe so that the cleaning fluid can flow back to the second chamber. The inlet end of the delivery pump is connected to the first chamber. The cleaning fluid storage tank is equipped with an electromagnetic adsorption component, through which the cleaning fluid in the second chamber can flow into the first chamber. The electromagnetic adsorption component can filter ferromagnetic impurities in the cleaning fluid.

[0017] By adopting the above technical solution, the cleaning fluid storage tank is divided into a first chamber and a second chamber by a partition, achieving classified storage of the cleaning fluid. A collection cylinder is used to collect the cleaning fluid after cleaning and returns it to the second chamber through a pipeline, forming a recycling system and reducing resource waste. An electromagnetic adsorption component is installed on the cleaning fluid storage tank, which can filter ferromagnetic impurities in the cleaning fluid in the second chamber, ensuring the cleanliness of the cleaning fluid and thus improving the cleaning effect on the bearing rings.

[0018] Preferably, a filter is connected in series on the pipeline between the delivery pump and the cleaning nozzle, and the filter is capable of filtering impurities in the cleaning fluid.

[0019] By adopting the above technical solution, the cleaning fluid is filtered through the filter on the pipeline during the process of being transported from the cleaning fluid storage tank to the cleaning nozzle. This effectively removes impurities from the cleaning fluid, preventing impurities from clogging the cleaning nozzle or re-contaminating the bearing ring surface, thereby improving the cleaning effect and the reliability of the equipment.

[0020] Preferably, it further includes a drying assembly; the drying assembly includes a second rotating seat, a linear rotation drive, and a nozzle; the second rotating seat is used to place the bearing ring; the linear rotation drive can press the bearing ring onto the second rotating seat and drive the bearing ring to rotate; the tail end of the nozzle is connected to a gas delivery system; the outlet of the nozzle faces the bearing ring so as to spray gas onto the bearing ring.

[0021] By adopting the above technical solution, the second rotating seat provides a stable placement platform for the bearing rings. The linear rotation drive can not only press and fix the bearing rings, but also drive the bearing rings to rotate, so that the gas sprayed from the air nozzle can act evenly on the surface of the bearing rings, thereby achieving the effect of rapid air drying.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When cleaning the bearing rings, first place the bearing rings on the first rotating seat, then rotate and fix the bearing rings on the first rotating seat, and drive the bearing rings to rotate. The cleaning nozzle sprays cleaning fluid onto the surface of the bearing rings, so that the impurities on the surface of the bearing rings are removed under the impact force of the cleaning fluid spray and the centrifugal force of the bearing rings rotating, thereby accelerating the cleaning speed of the impurities on the surface of the bearing rings and improving the cleaning efficiency.

[0024] 2. The collection cylinder is used to collect the cleaning fluid after cleaning and return the cleaning fluid to the second chamber through the pipeline. The cleaning fluid in the second chamber is filtered by the electromagnetic filter to adsorb ferromagnetic impurities and then flows into the first chamber. It is then pumped by the pump through the filter and flows into the cleaning nozzle, forming a recycling of the cleaning fluid and reducing resource waste.

[0025] 3. After cleaning, the bearing rings are placed on the second rotating seat. The linear rotation drive drives the bearing rings to rotate on the second rotating seat, so that the gas sprayed from the air nozzle can act evenly on the surface of the bearing rings, achieving rapid air drying of the bearing rings.

[0035] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0036] This application provides a bearing ring surface cleaning device.

[0037] Reference Figure 1 , Figure 2 A bearing ring surface cleaning device includes a first rotating seat 111, a rotation fixed drive assembly 112, a cleaning nozzle 113, and a drying assembly 12, all mounted on a workbench 2. The first rotating seat 111 is rotatably mounted on the workbench 2. The first rotating seat 111 includes a support platform 1111 and a rotating shaft. The rotating shaft is fixedly connected to the support platform 1111. The rotating shaft is rotatably connected to the workbench 2 in the vertical direction via a bearing. The support platform 1111 is a hollow disc shape, allowing the cleaning fluid to flow downward through the support platform 1111. A sliding guide frame 116 is fixedly installed on the workbench 2. A rotary fixed drive assembly 112 is installed on the sliding guide frame 116. The rotary fixed drive assembly 112 fixes the bearing ring 3 on the support table 1111 and drives the bearing ring 3 to rotate. A cleaning nozzle 113 is installed on the rotary fixed drive assembly 112. The tail end of the cleaning nozzle 113 is connected to the cleaning fluid supply system 10 through a pipe. The outlet end of the cleaning nozzle 113 faces the bearing ring 3.

[0038] When cleaning the bearing ring 3, the bearing ring 3 is first placed on the support platform 1111 of the first rotating seat 111. Then, the rotating and fixing drive assembly 112 presses the bearing ring 3 tightly onto the first rotating seat 111 and drives the bearing ring 3 to rotate. The cleaning nozzle 113 sprays cleaning fluid onto the surface of the bearing ring 3, so that the impurities on the surface of the bearing ring 3 are removed under the impact force of the cleaning fluid spray and the centrifugal force of the bearing ring 3's rotation. This can accelerate the cleaning speed of the impurities on the surface of the bearing ring 3 and improve the cleaning efficiency.

[0039] Reference Figure 1 The worktable 2 is provided with a collection cylinder 115 below the first rotating seat 111. The collection cylinder 115 is located below the first rotating seat 111 to collect the cleaning fluid passing through the support platform 1111. The bottom of the collection cylinder 115 is connected to the cleaning fluid supply system 10 through a return oil pipe. In this embodiment, the cleaning fluid is kerosene. When the cleaning fluid cleans the bearing ring 3, the cleaned cleaning fluid can flow into the collection cylinder 115 for collection. The cleaning fluid in the collection cylinder 115 flows back to the cleaning fluid supply system 10 along the return oil pipe, realizing the recycling of the cleaning fluid, reducing cleaning costs and reducing resource waste.

[0040] Reference Figure 1 , Figure 2 The rotary fixed drive assembly 112 includes a linear drive mechanism 1121, a rotary power component 1122, and a pressure block 1123. The linear drive mechanism 1121 includes a Z-axis cleaning linear cylinder 1124 and a cleaning frame 1125. The cylinder body of the Z-axis cleaning linear cylinder 1124 is fixedly connected to the sliding guide frame 116. The cleaning frame 1125 is slidably connected to the sliding guide frame 116 through a linear rail-slider mechanism. The piston rod of the Z-axis cleaning linear cylinder 1124 is fixedly connected to the cleaning frame 1125 and is used to drive the cleaning frame 1125 to slide along the Z-axis.

[0041] Reference Figure 2 , Figure 3The rotating power component 1122 includes a first rotating motor 1126 and a first drive rod 1171. In this embodiment, the first rotating motor 1126 is a servo motor. The housing of the first rotating motor 1126 is fixedly connected to the cleaning frame 1125. The output shaft of the first rotating motor 1126 is set downward and passes through the cleaning frame 1125. The first drive rod 1171 is coaxially fixedly connected to the output shaft of the first rotating motor 1126 through a coupling. The first drive rod 1171 is located above the first rotating seat 111. The pressure block 1123 is slidably sleeved on the first drive rod 1171. The top of the first drive rod 1171 protrudes outward to form a retaining ring 1172. An elastic element is provided on the first drive rod 1171. In this embodiment, the elastic element is a first telescopic spring 1173 sleeved on the first drive rod. One end of the first telescopic spring 1173 abuts against the retaining ring 1172, and the other end abuts against the pressure block 1123. The first telescopic spring 1173 provides elastic force, ensuring a stable compression between the pressure block 1123 and the bearing ring 3, thereby improving the fixing effect of the bearing ring 3 during the cleaning process.

[0042] Reference Figure 1 , Figure 3 The sidewall of the pressure block 1123 protrudes outward to form four extensions. The bottom of the extensions is an inclined surface. When the pressure block 1123 presses down on the bearing ring 3, it relies on the inclined surface at the bottom of the four extensions to contact the bearing ring 3 and thus press the bearing ring 3.

[0043] Reference Figure 3 , Figure 4 The bottom of the first drive rod 1171 protrudes outward to form a limiting ring 1174. The first telescopic spring 1173 presses the pressure block 1123 against the limiting ring 1174, and the limiting ring 1174 can prevent the pressure block 1123 from disengaging from the first drive rod 1171. A limiting key 1175 is fixedly provided on the first drive rod 1171 along its own circumferential direction. The pressure block 1123 is provided with a keyway 1176 that penetrates the upper and lower side walls. The limiting member passes through the keyway 1176 to realize that the pressure block 1123 slides along the axial direction of the first drive rod 1171, and the first drive rod 1171 drives the pressure block 1123 to rotate circumferentially.

[0044] Reference Figure 1 , Figure 2A transparent cover 118 is provided between the workbench 2 and the cleaning rack 1125. The transparent cover 118 is fixedly mounted on the cleaning rack 1125. In this embodiment, the transparent cover 118 is a glass cover. The transparent cover 118 covers the bearing ring 3 and the first drive rod 1171, which can prevent the cleaning fluid from splashing everywhere, thereby keeping the workbench 2 clean. There are three cleaning nozzles 113, all of which are fixedly mounted on the cleaning rack 1125. The tail of the cleaning nozzle 113 is connected to the cleaning fluid supply system 10 through a flexible pipe. The outlet of the nozzle passes through the cleaning rack 1125 and is directed toward the bearing ring 3 to spray cleaning fluid onto the bearing ring 3.

[0045] When cleaning the bearing ring 3, the bearing ring 3 is placed on the support platform 1111 on the first rotating seat 111. Then, the cleaning frame 1125 is driven to move down by the Z-axis cleaning linear cylinder 1124, so that the pressure block 1123 presses the bearing ring 3 firmly on the first rotating seat 111. Then, the cleaning nozzle 113 sprays cleaning fluid onto the bearing ring 3. Then, the first rotating motor 1126 drives the first drive rod 1171 to rotate. The first drive rod 1171 drives the pressure block 1123 to rotate. The pressure block 1123 drives the bearing ring 3 to rotate on the first rotating seat 111, so that the cleaning fluid can spray and clean the bearing ring 3 from all directions, thereby improving the cleanliness of the cleaning. The first telescopic spring 1173 between the pressure block 1123 and the first drive rod 1171 is designed to provide a stable clamping force when pressing the bearing ring 3, ensuring that the bearing ring 3 will not slip or shift when the rotating power component 1122 drives the pressure block 1123 to rotate, thereby improving the stability of the bearing ring 3 during the cleaning process.

[0046] Reference Figure 5 , Figure 6The cleaning fluid supply system 10 includes a cleaning fluid storage tank 101 and a transfer pump 102. The cleaning fluid storage tank 101 is divided into a first chamber 1011 and a second chamber 1012 by a partition 103. The height of the cleaning fluid storage tank 101 is lower than the height of the collection cylinder 115, so that the cleaning fluid can flow back smoothly to the cleaning fluid storage tank 101 after cleaning. In this embodiment, the transfer pump 102 is an oil pump. The inlet end of the transfer pump 102 is connected to the first chamber 1011 through a pipe, and the bottom of the collection cylinder 115 is connected to the second chamber 1012 through a pipe, so that the cleaning fluid flows back to the second chamber 1012. An overflow port 1013 is provided on the top of the partition 103, allowing the cleaning fluid in the second chamber 1012 to flow into the first chamber 1011 through the overflow port 1013. The cleaning fluid storage tank 101 is equipped with an electromagnetic adsorption element 104 at the overflow port 1013. In this embodiment, the electromagnetic adsorption element 104 is an electromagnetic adsorption element 104. When the cleaning fluid in the second chamber 1012 flows into the first chamber 1011 through the overflow port 1013, it passes through the electromagnetic adsorption element 104. The electromagnetic adsorption element 104 adsorbs ferromagnetic impurities in the flowing cleaning fluid, thus filtering the cleaning fluid and improving its cleanliness. When the cleaning fluid flows back to the second chamber 1012, debris settles in the second chamber 1012, completing the sedimentation of the debris.

[0047] Reference Figure 5 , Figure 6 A filter 105 is connected in series on the pipeline between the outlet of the transfer pump 102 and the cleaning nozzle 113. There are two filters 105 connected in series at the outlet of the transfer pump 102 via a pipeline. Each filter 105 contains a filter element to filter impurities in the cleaning fluid. The outlet of the downstream filter 105 is connected to the three cleaning nozzles 113 via a pipeline to supply cleaning fluid to the cleaning nozzles 113. An electromagnetic filter 106 is connected in series on the pipeline between the upstream filter 105 and the transfer pump 102. The electromagnetic filter 106 adsorbs and filters impurities in the cleaning fluid, further improving the cleanliness of the cleaning fluid.

[0048] Reference Figure 1 , Figure 7The air-drying assembly 12 includes a second rotating seat 121, a linear rotation drive 122, and an air nozzle 123. The second rotating seat 121 has the same structure as the first rotating seat 111. The second rotating seat 121 is rotatably mounted on the worktable 2, and the bearing ring 3 is placed on the support platform 1111 of the second rotating seat 121. The linear rotation drive 122 includes a Z-axis air-drying linear cylinder 1221, an air-drying frame 1222, and a second servo motor 1223. The cylinder body of the Z-axis air-drying linear cylinder 1221 is fixedly mounted on the sliding guide frame 116, and the air-drying frame 1222 is slidably mounted on the sliding guide frame 116 through a linear rail-slider structure. The piston rod of the Z-axis air-drying linear cylinder 1221 is fixedly connected to the air-drying frame 1222. The housing of the second servo motor 1223 is fixedly mounted on the drying rack 1222, and the output shaft of the second servo motor 1223 is set downward and passes through the drying rack 1222. One end of the output shaft of the second servo motor 1223 passing through the drying rack 1222 is connected to the second drive rod 1224 via a coupling. A clamping block 1225 is slidably sleeved on the second drive rod 1224. The top of the second drive rod 1224 protrudes outward to form a spring ring. A second telescopic spring 1226 is sleeved on the second drive rod 1224. One end of the second telescopic spring 1226 abuts against the spring switch, and the other end abuts against the clamping block 1225. The bottom of the second drive rod 1224 protrudes outward to form a limiting part. The second telescopic spring 1226 squeezes the clamping block 1225 and abuts against the limiting part to prevent the clamping block 1225 from disengaging from the second drive rod 1224.

[0049] Reference Figure 1 , Figure 7 The second drive rod 1224 is also connected to the clamping block 1225 using a limit key-keyway method, allowing the second drive rod 1224 and the clamping block 1225 to slide axially and drive the clamping block 1225 to rotate. The bottom of the clamping block 1225 is concave, making the clamping block 1225 stepped. When the clamping block 1225 presses against the bearing ring 3, the narrower part of the bottom of the clamping block 1123 inserts into the bearing ring 3, while the wider part presses against the bearing ring 3, thus pressing the bearing ring 3 against the second rotating seat.

[0050] Reference Figure 1 , Figure 7The tail end of the air nozzle 123 is connected to a gas delivery system via a flexible pipe. The gas delivery system includes, but is not limited to, a fan or a high-pressure gas cylinder. The outlet of the air nozzle 123 passes through the drying rack 1222. A bamboo-joint tube 124 is provided at the end of the air nozzle 123 that passes through the drying rack 1222, allowing ventilation and promoting uniform drying. A receiving cylinder 125 is provided below the second rotating seat 121 on the mounting bracket. The bottom of the receiving cylinder 125 is connected to the second cavity 1012 via a pipe. The height of the receiving cylinder 125 is higher than the height of the cleaning fluid storage tank 101, allowing the cleaning fluid falling from the bearing ring 3 to flow into the second cavity 1012.

[0051] Reference Figure 8 A protective cover 126 is fixedly installed on the drying rack 1222. The protective cover 126 is divided into inner and outer layers. The inner layer is a hollow steel cover and the outer layer is a glass cover. When the clamping block 1225 presses the bearing ring 3 onto the second rotating seat 121, the protective cover 126 covers the space above the bearing ring 3. On the one hand, it can prevent the cleaning fluid from splashing. On the other hand, because the drying speed is too high, the high rigidity of the inner steel cover can effectively prevent the bearing ring 3 from falling off and flying out, thus improving safety.

[0052] The implementation principle of a bearing ring surface cleaning device according to an embodiment of this application is as follows: When cleaning the bearing ring 3, the bearing ring 3 is first placed on the support platform 1111 of the first rotating seat 111. Then, the rotation and fixing drive assembly 112 presses and fixes the bearing ring 3 on the first rotating seat 111 and drives the bearing ring 3 to rotate. The cleaning nozzle 113 sprays cleaning fluid onto the surface of the bearing ring 3, so that the impurities on the surface of the bearing ring 3 are removed under the impact force of the cleaning fluid spray and the centrifugal force of the bearing ring 3's rotation. This can accelerate the cleaning speed of the impurities on the surface of the bearing ring 3 and improve the cleaning efficiency.

[0053] The cleaning fluid collected in the collection cylinder 115 after cleaning is returned to the second chamber 1012 through the pipeline. The cleaning fluid in the second chamber 1012 flows into the first chamber 1011 through the electromagnetic adsorption component 104 of the overflow port 1013. The delivery pump 102 delivers the cleaning fluid in the first chamber 1011 to the cleaning nozzle 113 through the pipeline, thereby realizing the recycling of the cleaning fluid.

[0054] The cleaned bearing ring 3 is placed on the support platform of the second rotating seat 121. The Z-axis drying linear cylinder 1221 drives the clamping block 1225 to press and fix the bearing ring 3 on the second rotating seat 121. The second servo motor 1223 drives the bearing ring 3 to rotate. The gas delivery system blows gas to the bearing ring 3 through the air nozzle 123 to dry the bearing ring 3.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
