Description

TECHNICAL FIELD

[0001] The present application relates to the field of deep groove ball bearing processing, more particularly, it relates to a deep groove ball bearing oiling and drying device and a using method thereof. BACKGROUND

[0002] As a widely used basic part in the field of mechanical transmission, the rust-proof treatment of the outer side wall of the deep groove ball bearing directly affects the storage life and use performance of the bearing. At present, the oiling (anti-rust oil) method is generally used in the industry to treat the outer side wall of the bearing.

[0003] However, the existing oiling equipment has many deficiencies: first, most of the equipment only uses a single circumferential limiting structure (such as a simple circular ring) or a radial clamping structure, lacks a collaborative design of "precise positioning + stable fixation", and when only relying on circumferential limiting, the bearing is prone to radial displacement and shaking during high-speed rotation, oiling or drying, resulting in inconsistent spacing between the outer side wall and the nozzle, and problems such as local oil film being too thick, too thin or missing; when only relying on radial clamping, if there is no precise positioning in advance, the bearing center is easy to deviate, which not only affects the uniformity of oiling, but also may cause the bearing surface to be pressed due to the concentration of clamping force; secondly, some equipment does not configure oil heating and stirring functions, when using high-viscosity anti-rust oil or operating in a low-temperature environment, the oil flowability is poor, and the additives in the anti-rust oil are easy to precipitate and stratify, affecting the oiling effect and rust-proof performance; finally, the position of the oiling assembly is fixed and cannot be adjusted in height according to the bearing specifications, which has poor adaptability and is difficult to meet the batch efficient processing needs of deep groove ball bearings of different sizes.

[0004] Therefore, in order to solve the above technical problems, the present application provides a deep groove ball bearing oiling and drying device and a using method thereof. SUMMARY

[0005] In view of the deficiencies of the prior art, the purpose of the present application is to provide a deep groove ball bearing oiling and drying device and a using method thereof.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a deep groove ball bearing oiling and drying device for oiling the outer side wall of the deep groove ball bearing, comprising: A recovery bucket, a motor A is installed at the center of the inner bottom wall of the recovery bucket through a support column, an output end of the motor A is installed with a placing table, and a limiting ring is fixedly connected to the top of the placing table, the deep groove ball bearing is placed on the placing table by the mechanical arm, and is circumferentially limited by the limiting ring, and the rotation of the deep groove ball bearing is realized by adjusting the rotating speed of the motor A, and the oiling and drying operation is realized. A fixing component is installed inside a limiting ring. The limiting ring has through slots A on both sides. The fixing component includes two clamping plates arranged opposite each other, and a pushing component for driving the two clamping plates to move in opposite directions and extend out of the through slots A to clamp the deep groove ball bearing. The oil spraying assembly, located directly above the recycling tank, includes an oil storage tank. The top of the oil storage tank is connected to an oil delivery hose via an oil pump. Multiple electric spray nozzles are arranged in a circular array at the bottom of the oil storage tank. Heating and stirring components are installed inside the oil storage tank. The lifting assembly, installed on the side of the recycling bin, drives the oil storage tank to move vertically up and down. When the oil storage tank moves upward, it leaves clearance for the robotic arm to place the deep groove ball bearing onto the placement platform. After the bearing is placed, the oil storage tank moves downward to return to the oil spraying station. Preferably, the pushing component includes a connecting plate fixed in the middle of the limiting ring, and an electro-hydraulic rod is installed on both sides of the connecting plate. The output ends of the two electro-hydraulic rods are respectively connected to the two clamping plates, and the movement of the clamping plates is driven by the extension and retraction of the electro-hydraulic rods.

[0007] Preferably, the oil storage tank includes a tank body and a detachably connected top cover, the oil pump is installed on the top of the top cover, and the electric nozzles are evenly distributed at the bottom of the tank body and communicate with the inside of the tank body.

[0008] Preferably, the heating component includes a heating tube fixedly installed on the bottom wall of the tank, and the heating tube is electrically connected to an external temperature controller.

[0009] Preferably, the stirring component includes an internal gear ring fixed to the inner side wall of the top cover. A motor B is installed at the center of the top of the top cover. The output end of the motor B passes through the top cover and is connected to the rotating plate. A pinion is rotatably connected to the bottom of the rotating plate through a connecting bearing. The pinion meshes with the internal gear ring. A stirring paddle is fixedly connected to the bottom of the pinion. When the motor B drives the rotating plate to rotate, the pinion drives the stirring paddle to move synchronously as it rolls and meshes with the internal gear ring. This causes the stirring paddle to revolve around the axis of the heating tube and rotate around its own axis.

[0010] Preferably, the lifting assembly includes a support platform fixed to the side of the recycling bin. The top of the support platform is fixedly connected to a housing with an opening facing the recycling bin. A lead screw driven by a motor C is rotatably installed inside the housing. A rod sleeve is threadedly connected to the outer wall of the lead screw. Guide rails A are fixedly connected to both sides of the inside of the housing. A slider A is slidably connected to each guide rail A. Both sides of the rod sleeve are connected to the slider A through connecting rods A. The surface of the rod sleeve is connected to the oil storage tank through connecting rods B.

[0011] Preferably, the motor A is covered with a protective shell, and the output end of the motor A is detachably connected to the placement platform via a quick-release assembly.

[0012] Preferably, the quick-release assembly includes a top block fixedly installed at the output end of motor A. The bottom end of the placement platform is fixedly connected to a lower open slot seat that can be fitted onto the top block. Guide rails B are fixedly connected to both sides of the lower open slot seat. A slider B is slidably connected to the guide rails B. The surface of the slider B is fixedly connected to a movable plate via a connecting rod C. There are two movable plates located on the front and rear sides of the lower open slot seat. The front ends of the lower open slot seat are provided with through slots B. The front and rear ends of the top block are provided with grooves that fit the through slots B. When the lower open slot seat is fitted onto the top block, the through slots B and the grooves are aligned. The opposite side of each movable plate is fixedly connected with a locking block that can pass through the through slots B and be inserted into the grooves. The front and rear ends of the lower open slot seat are fixedly connected to the two sides of the through slots B. The movable plate is provided with a through hole for the screw to pass through. The outer side wall of the screw is threaded with a locking nut for locking the movable plate.

[0013] Preferably, anti-slip pads are installed on the contact surfaces of the two clamping plates and the deep groove ball bearing. The anti-slip pads have anti-slip textures on their surfaces and are made of oil-resistant rubber.

[0014] The method for using the above-mentioned oil spraying and drying equipment for deep groove ball bearings includes the following steps: Step 1: Confirm that the outer protective shell of motor A is installed properly, the quick-release assembly is securely fixed with the lock nut, and the placement platform and the limit ring are compatible with the specifications of the deep groove ball bearing to be processed; check that the guide rail A, slider A and lead screw of the lifting assembly are not stuck, and that the electric nozzle is unobstructed. Step 2: Start the oil pump. The oil pump generates pumping power to deliver the rust-preventive oil through the oil hose to the oil storage tank until a sufficient amount of rust-preventive oil is injected and temporarily stored. According to the viscosity of the rust-preventive oil or the ambient temperature, start the heating element of the heating component and set the appropriate temperature through the external temperature controller. At the same time, start the motor B of the stirring component to drive the stirring paddle to perform a combined revolution and rotation motion to heat and stir the oil, ensuring good oil flow and uniform dispersion of additives. Step 3: Start the motor C of the lifting assembly to rotate in the forward direction, which will drive the rod sleeve and oil storage tank to move upward along the guide rail A, leaving clearance space; Step 4: The robotic arm picks up the deep groove ball bearing to be oiled and precisely places it on the placement platform inside the recycling bin. The circumferential positioning of the deep groove ball bearing is achieved by the limiting ring. Step 5: Activate the electro-hydraulic rod of the fixing component. The electro-hydraulic rod extends and drives the two clamping plates to move in opposite directions. They extend out from the through grooves A on both sides of the limiting ring and radially clamp the bearing through the oil-resistant rubber anti-slip pad with anti-slip texture on the surface, realizing "circumferential limiting + radial fixing" to ensure that the center of the deep groove ball bearing does not shift. Step 6: Start the motor C of the lifting assembly to rotate in the opposite direction, driving the oil storage tank to move downward. Adjust the downward height of the oil storage tank flexibly according to the size of the deep groove ball bearing, and stop after the electric nozzle and the outer wall of the deep groove ball bearing are properly matched. Step 7: Turn on the multiple electric nozzles at the bottom of the oil storage tank to spray oil onto the outer wall of the deep groove ball bearing; at the same time, start motor A to drive the placement platform to rotate the deep groove ball bearing at a constant speed, ensuring that the outer wall of the deep groove ball bearing is in full and uniform contact with the oil, and complete the oil spraying operation. Step 8: After the oiling is completed, adjust the speed of motor A and use centrifugal force to spin dry the deep groove ball bearing. Excess oil will fall into the recycling bin for recycling and reuse. Step 9: After the spin-drying is completed, turn off motor A, start the electric hydraulic rod of the fixing component to retract, drive the two clamping plates to move towards each other and retract into the limit ring, release the radial fixation of the deep groove ball bearing, start the motor C of the lifting component to rotate forward, drive the oil storage tank to move upward to leave clearance space, the robotic arm extends into the equipment to grab the deep groove ball bearing that has been sprayed with oil and spun dry, and transfer it to the next process to complete a single operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a limiting ring on a placement platform to precisely position the bearing circumferentially. Then, a fixing component inside the limiting ring drives two opposing clamping plates to move back and forth through a pushing component, so that they extend out of the through grooves A on both sides of the limiting ring and clamp the bearing radially. Through the coordinated design of "circumferential limiting + radial fixing", this invention effectively solves the problems of easy displacement due to single limiting and easy center offset or damage to the bearing in the prior art. 2. The present invention uses a heating component inside the oil storage tank to heat the oil to improve its fluidity, and at the same time uses a stirring component to stir the oil to prevent additives from settling and separating, thus solving the problem of poor oil spraying effect in high viscosity oil or low temperature environment in the prior art. 3. The present invention flexibly adjusts the downward height of the oil storage tank through the lifting component, adapting to deep groove ball bearings of different sizes, thus improving the poor adaptability of existing equipment and solving the problem of fixed position of the oil spraying component in the background technology; 4. This invention can increase the friction between the clamping plate and the bearing surface through the anti-slip texture, effectively preventing the bearing from sliding relative to each other due to centrifugal force during the oil spraying or spin drying process driven by motor A. This further ensures the synergistic stability effect of "circumferential limiting + radial fixing", ensuring that the distance between the outer wall of the bearing and the electric nozzle is always consistent, and improving the uniformity of oiling. 5. The present invention connects the output end of motor A to the placement table in a detachable manner through a quick-release assembly, which facilitates the quick disassembly and replacement of the appropriate placement table and limiting ring according to the different specifications of the deep groove ball bearings to be processed. This greatly improves the equipment's adaptability to multiple bearing models and meets the processing needs of deep groove ball bearings of different sizes in batch processing.

[0018] Example 1 like Figures 1-3 As shown, the present invention provides an oil spraying and drying device for deep groove ball bearings, used for applying oil to the outer wall of the deep groove ball bearing, comprising: The recycling bin 1 has a motor A3 installed at the center of its inner bottom wall via a support column 2. The output end of the motor A3 is equipped with a placement platform 4, and a limiting ring 5 is fixedly connected to the top of the placement platform 4. The deep groove ball bearing is placed on the placement platform 4 by a robotic arm and is circumferentially limited by the limiting ring 5. By adjusting the speed of the motor A3, the rotation, oiling, and spin-drying operations of the deep groove ball bearing can be achieved. The fixing component 6 is installed inside the limiting ring 5. The limiting ring 5 has through grooves A501 on both sides. The fixing component 6 includes two clamping plates 601 arranged opposite to each other, and a pushing component 602 for driving the two clamping plates 601 to move in opposite directions and extend out of the through grooves A501 to clamp the deep groove ball bearing. The oil spraying assembly 7 is located directly above the recycling tank 1 and includes an oil storage tank 701. The top of the oil storage tank 701 is connected to the oil delivery hose 703 via an oil pump 702. The bottom of the oil storage tank 701 has multiple electric nozzles 704 arranged in a circumferential array. The oil storage tank 701 is equipped with a heating component 705 and a stirring component 706. The lifting assembly 8 is installed on the side of the recycling bin 1 and is used to drive the oil storage tank 701 to move up and down in the vertical direction. When the oil storage tank 701 moves upward, it leaves clearance space for the robotic arm to place the deep groove ball bearing on the placement table 4. After the bearing is placed, the oil storage tank 701 moves downward to reset to the oil spraying processing station.

[0019] In use, firstly, the oil pump 702 acts on the oil hose 703 to add sufficient rust-preventive oil to the oil storage tank 701 for temporary storage. Then, the lifting assembly 8 drives the oil storage tank 701 to move vertically upward, leaving clearance so that the robotic arm can accurately place the deep groove ball bearing on the placement platform 4 above the support column 2 at the center of the bottom wall of the recycling bin 1. First, the bearing is precisely circumferentially positioned by the limiting ring 5 on the placement platform 4. Then, the fixing assembly 6 inside the limiting ring 5 pushes the bearing to achieve the same position. 602 drives two opposing clamping plates 601 to move back to back, causing them to extend from the through grooves A501 on both sides of the limiting ring 5 and radially clamp the bearing (when the pushing component 602 drives the clamping plates 601 to move towards each other, the fixing of the bearing is released). Through the coordinated design of "circumferential limiting + radial fixing", the problems of easy displacement due to single limiting and easy center offset or bearing damage due to single clamping in existing equipment are effectively solved, ensuring that the distance between the outer wall of the deep groove ball bearing and the electric nozzle 704 is consistent; bearing fixing. After completion, depending on the viscosity of the rust-preventive oil or the ambient temperature, the heating component 705 inside the oil storage tank 701 is activated to heat the oil and improve its fluidity. At the same time, the stirring component 706 stirs the oil to prevent additives from settling and separating, solving the problem of poor oiling effect in high-viscosity oil or low-temperature environments. Next, the oil storage tank 701 is lowered to the processing station by the lifting component 8. At this time, the lowering height of the oil storage tank 701 can be flexibly adjusted by the lifting component 8 to adapt to deep groove ball bearings of different sizes, improving the poor adaptability of existing equipment. Afterwards, multiple electric nozzles 704 arranged in a circumferential array at the bottom of the oil storage tank 701 spray oil onto the outer wall of the bearing. At the same time, the motor A3 (equipped with a reducer) drives the placement platform 4 to rotate the bearing to achieve all-round uniform oiling. After the oiling is completed, the speed of the motor A3 is adjusted, and the bearing is spun dry by centrifugal force. Excess oil falls into the recycling bin 1 for easy recycling and reuse. Finally, the batch, efficient and uniform oiling treatment of deep groove ball bearings of different sizes is achieved.

[0020] The following is the specific structure of the pushing component 602: The pushing component 602 includes a connecting plate 6021 fixed in the middle of the limiting ring 5, and electric hydraulic rods 6022 are installed on both sides of the connecting plate 6021. The output ends of the two electric hydraulic rods 6022 are respectively connected to the two clamping plates 601, and the clamping plates 601 are moved by the extension and retraction of the electric hydraulic rods 6022.

[0021] The pushing component 602 is fixedly installed in the middle of the limiting ring 5 via the connecting plate 6021, forming a stable installation base. The electro-hydraulic rods 6022 installed on both sides of the connecting plate 6021 serve as power sources, and their output ends are fixedly connected to two oppositely arranged clamping plates 601. After the deep groove ball bearing completes precise circumferential positioning via the limiting ring 5, the electro-hydraulic rods 6022 start and extend, driving the two clamping plates 601 to move in opposite directions, so that they extend out of the through grooves A501 on both sides of the limiting ring 5, and radially support the bearing. The system performs a smooth clamping action, which, in conjunction with the circumferential limiting ring 5, achieves a synergistic effect of "circumferential limiting + radial fixing". The driving force of the electro-hydraulic rod 6022 is stable and controllable, which can avoid bearing surface damage caused by concentrated clamping force, while ensuring that the bearing center does not shift and that the distance between it and the electric nozzle 704 is consistent. After the oil spraying and drying operation is completed, the electro-hydraulic rod 6022 retracts, driving the two clamping plates 601 to move towards each other and retract into the limiting ring 5, releasing the radial fixing of the bearing so that the robotic arm can smoothly pick up and put down the bearing.

[0022] Furthermore, anti-slip pads 6011 are installed on the contact surfaces of the two clamping plates 601 and the deep groove ball bearing. The surface of the anti-slip pads 6011 is provided with anti-slip textures, and the anti-slip pads 6011 are made of oil-resistant rubber. On the one hand, the anti-slip textures increase the friction between the clamping plates 601 and the bearing surface, effectively preventing the bearing from sliding relative to the bearing due to centrifugal force during the oil spraying or spin-drying process driven by motor A3. This further ensures the synergistic stability of "circumferential limiting + radial fixing", ensuring that the distance between the outer wall of the bearing and the electric spray head 704 is always consistent, and improving the uniformity of oiling. On the other hand, the oil-resistant rubber material has good oil resistance and anti-aging properties, which can resist the corrosion of rust-preventive oil, avoid material deterioration and failure after long-term use, and extend the service life of the anti-slip pads 6011. At the same time, the flexibility of the rubber material can form a buffer, avoiding surface pressure and scratches caused by hard contact between the clamping plates 601 and the bearing, protecting the appearance and precision of the bearing.

[0023] Example 2 like Figures 6-8As shown in the figure, this embodiment provides the specific structure of the oil storage tank 701, heating component 705, and stirring component 706 in Embodiment 1: The oil storage tank 701 includes a tank body 7011 and a detachably connected top cover 7012. The oil pump 702 is installed on the top of the top cover 7012. The electric nozzles 704 are evenly distributed at the bottom of the tank body 7011 and communicate with the interior of the tank body 7011. The heating component 705 includes a heating pipe 7051 fixedly installed on the inner bottom wall of the tank body 7011. The heating pipe 7051 is electrically connected to an external temperature controller. The stirring component 706 includes an internal gear ring 7061 fixed on the inner side wall of the top cover 7012 and the top of the top cover 7012... A motor B7062 is installed in the center. The output end of the motor B7062 passes through the top cover 7012 and is connected to the rotating plate 7063. The bottom end of the rotating plate 7063 is rotatably connected to a pinion 7065 through a connecting bearing 7064. The pinion 7065 meshes with an internal gear ring 7061. The bottom end of the pinion 7065 is fixedly connected to a stirring paddle 7066. When the motor B7062 drives the rotating plate 7063 to rotate, the pinion 7065 drives the stirring paddle 7066 to move synchronously as it rolls and meshes with the internal gear ring 7061. This causes the stirring paddle 7066 to revolve around the axis of the heating tube 7051 and rotate around its own axis.

[0024] The oil storage tank 701, through the combination structure of the tank body 7011 and the detachable top cover 7012, not only realizes the function of temporarily storing rust-preventive oil, but also facilitates the later maintenance and repair of internal components. After the oil pump 702 is started, it generates pumping power to deliver the rust-preventive oil into the tank body 7011 through the oil delivery hose 703 until a sufficient amount of rust-preventive oil is injected and temporarily stored. According to the viscosity of the rust-preventive oil or the ambient temperature requirements, the heating tube 7051 fixedly installed on the bottom wall of the tank body 7011 can be activated. The heating tube 7051 is electrically connected to an external temperature controller, which can accurately control the heating temperature of the oil, effectively improving the fluidity of high-viscosity oil or solving the problem of oil solidification in low-temperature environments. At the same time, the motor B7062 at the top center of the top of the top cover 7012 is started, and its output end drives the rotating plate 7063 to rotate. The bottom end of the rotating plate 7063 is connected to the bearing 70 The pinion 7065, which is rotatably connected to the top cover 7012, meshes with the internal gear ring 7061 on the inner side wall. While revolving with the rotating plate 7063, it also rotates on its own axis. This, in turn, drives the stirring paddle 7066, which is fixed at the bottom of the pinion 7065, to revolve around the axis of the heating tube 7051 and rotate on its own axis. This achieves all-round stirring of the oil in the tank 7011, preventing the additives in the rust-preventive oil from settling and separating, and ensuring the uniformity of the oil composition. The precise temperature control of the heating tube 7051 and the combined motion of the stirring paddle 7066 work together to keep the oil in good fluidity and uniformity. Finally, through the electric nozzles 704, which are evenly distributed at the bottom of the tank 7011 and connected to the interior, a stable and uniform oil is sprayed onto the outer wall of the bearing, ensuring the oil spraying effect and the rust prevention performance of the deep groove ball bearing.

[0025] Example 3 like Figures 1-2 As shown in the figure, this embodiment provides the specific structure of the lifting assembly 8 in embodiment 1: the lifting assembly 8 includes a support platform 801 fixed to the side of the recycling bin 1, the top of the support platform 801 is fixedly connected to a housing 802 with an opening facing the side of the recycling bin 1, a lead screw 804 driven by a motor C803 is rotatably installed inside the housing 802, a rod sleeve 805 is threadedly connected to the outer wall of the lead screw 804, guide rails A806 are fixedly connected to both sides of the inside of the housing 802, sliders A807 are slidably connected to both guide rails A806, both sides of the rod sleeve 805 are connected to the sliders A807 through connecting rods A808, and the surface of the rod sleeve 805 is connected to the oil storage tank 701 through connecting rods B809.

[0026] When the bearing needs to be picked up or put down, motor C803 starts and drives the lead screw 804, which is rotatably mounted inside the housing 802, to rotate in the forward direction (motor C803 is a bidirectional motor and can be controlled to rotate in either direction). Since the lead screw 804 is threadedly connected to the sleeve 805, and the sleeve 805 is fixedly connected to the sliders A807 slidably connected to the guide rails A806 on both sides inside the housing 802 via connecting rods A808 on both sides, the cooperation between the guide rails A806 and the sliders A807 restricts the sleeve 805 from rotating synchronously with the lead screw 804. This converts the rotational motion of the lead screw 804 into the vertical linear motion of the sleeve 805 along the axis of the lead screw 804. 05 is fixedly connected to the oil storage tank 701 via the connecting rod B809 on the surface, thereby driving the oil storage tank 701 to move upward synchronously, leaving enough clearance for the robotic arm to operate; after the bearing is placed or removed, the motor C803 rotates in the reverse direction, driving the lead screw 804 to rotate in the reverse direction, driving the sleeve 805 and the oil storage tank 701 to move downward and reset to the oil spraying processing position. Through the forward and reverse rotation of the motor C803 and the precise transmission of the lead screw 804, the lifting height of the oil storage tank 701 can be flexibly adjusted to adapt to the oil spraying requirements of deep groove ball bearings of different sizes, effectively solving the problem of fixed position and poor adaptability of the existing equipment oil spraying component 7.

[0027] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5As shown, this embodiment also includes a protective shell around the motor A3. Furthermore, the output end of the motor A3 is detachably connected to the placement platform 4 via a quick-release assembly 9. This protective shell effectively prevents splashed oil, oil mist, and any impurities that may be generated during the oil spraying and drying process from entering the motor, thus avoiding short circuits, corrosion, or wear of internal transmission components and ensuring the operational stability and lifespan of the motor A3. The detachable connection between the output end of the motor A3 and the placement platform 4 via the quick-release assembly 9 facilitates quick disassembly and replacement of the appropriate placement platform 4 and limiting ring 5 according to the different specifications of the deep groove ball bearings to be processed. This significantly improves the equipment's adaptability to various bearing models, meeting the processing needs of deep groove ball bearings of different sizes in batch processing. Furthermore, if the placement platform 4 or the limiting ring 5 experiences wear or malfunction, the motor A3 can be quickly separated from the placement platform 4 without complex disassembly tools, shortening maintenance and repair time, reducing operational difficulty, and ultimately improving the overall operating efficiency and ease of use of the equipment.

[0028] The following is the specific structure of the quick-release assembly 9: The quick-release assembly 9 includes a top block 901 fixedly installed at the output end of motor A3. A lower opening slot seat 902, which can be fitted onto the top block 901, is fixedly connected to the bottom end of the placement platform 4. Guide rails B903 are fixedly connected to both sides of the lower opening slot seat 902. A slider B904 is slidably connected to the guide rails B903. The surface of the slider B904 is fixedly connected to a moving plate 906 via a connecting rod C905. There are two moving plates 906 located on the front and rear sides of the lower opening slot seat 902. Through slots B9021 are opened at both ends of the front end of the lower opening slot seat 902. The top block 901... Both ends of the lower opening slot 902 have grooves 9011 that are adapted to the through slot B9021. When the lower opening slot seat 902 is fitted onto the top block 901, the through slot B9021 and the groove 9011 are aligned. The opposite side of the moving plate 906 is fixedly connected with a locking block 907 that can pass through the through slot B9021 and be inserted into the groove 9011. Both ends of the lower opening slot seat 902 are fixedly connected with screws 908 on both sides of the through slot B9021. The moving plate 906 has a through hole 9061 for the screws 908 to pass through. The outer side wall of the screws 908 is threaded with a locking nut for locking the moving plate 906.

[0029] During assembly, first align the lower opening slot seat 902 at the bottom of the placement platform 4 with the top block 901 at the output end of motor A3, and insert the lower opening slot seat 902 into the top block 901. After it is fully inserted, the through slots B9021 at both ends of the front end of the lower opening slot seat 902 are precisely aligned with the grooves 9011 at both ends of the front and rear ends of the top block 901. Then, push the two movable plates 906 located on the front and rear sides of the lower opening slot seat 902, causing the slider B904 to slide towards each other along the guide rail B903. This allows the locking blocks 907 on the opposite side of the movable plates 906 to pass through the through slots B9021 and insert into the grooves 9011 to achieve initial fixation. At this time, the movable plates 906 are in close contact with the surface of the lower opening slot seat 902. The through hole 9061 on the movable plate 906 passes through the screw 908. Finally, the locking nut is installed on the screw 908 and tightened to secure the position of the movable plate 906, completing the assembly of the quick-release component 9. When disassembling, first loosen and remove the locking nut on the screw 908, then pull the two movable plates 906 to drive the slider B904 to slide back and forth along the guide rail B903, so that the locking block 907 can be pulled out from the groove 9011 and the through groove B9021, releasing the fixation between the top block 901 and the lower opening slot seat 902. Finally, pull the lower opening slot seat 902 off the top block 901 to separate the placement platform 4 from the output end of the motor A3, making disassembly and assembly convenient.

[0030] This invention also provides a method for using the above-mentioned oil spraying and drying equipment for deep groove ball bearings: Step 1: Confirm that the outer protective shell of motor A3 is installed properly, quick-release assembly 9 is securely fixed with locking nuts, and the placement platform 4 and the limiting ring 5 are compatible with the specifications of the deep groove ball bearing to be processed; check that the guide rail A806, slider A807 and lead screw 804 of lifting assembly 8 are not stuck, and that the electric nozzle 704 is unobstructed. Step 2: Start the oil pump 702. The oil pump 702 generates pumping power to deliver the rust-preventive oil through the oil hose 703 to the tank 7011 of the oil storage tank 701 until a sufficient amount of rust-preventive oil is injected and temporarily stored. According to the viscosity of the rust-preventive oil or the ambient temperature, start the heating tube 7051 of the heating component 705 and set a suitable temperature through the external temperature controller. At the same time, start the motor B7062 of the stirring component 706 to drive the stirring paddle 7066 to perform a combined revolution and rotation motion to heat and stir the oil, ensuring good oil flow and uniform dispersion of additives. Step 3: Start the motor C803 of the lifting assembly 8 to rotate forward, driving the rod sleeve 805 and the oil storage tank 701 to move upward along the guide rail A806, leaving clearance space; Step 4: The robotic arm picks up the deep groove ball bearing to be oiled and precisely places it on the placement platform 4 inside the recycling bin 1. The deep groove ball bearing is precisely positioned circumferentially by the limiting ring 5. Step 5: Activate the electric hydraulic rod 6022 of the fixing component 6. The electric hydraulic rod 6022 extends and drives the two clamping plates 601 to move in opposite directions. They extend out from the through grooves A501 on both sides of the limiting ring 5 and radially clamp the bearing through the oil-resistant rubber anti-slip pads 6011 with anti-slip texture on the surface, realizing "circumferential limiting + radial fixing" to ensure that the center of the deep groove ball bearing does not shift. Step 6: Start the motor C803 of the lifting assembly 8 to rotate in the opposite direction, driving the oil storage tank 701 to move downward. Adjust the downward height of the oil storage tank 701 flexibly according to the size of the deep groove ball bearing, and stop after the electric nozzle 704 and the outer wall of the deep groove ball bearing are properly matched. Step 7: Turn on the multiple electric nozzles 704 at the bottom of the oil storage tank 701 to spray oil onto the outer wall of the deep groove ball bearing; at the same time, start the motor A3 to drive the placement platform 4 to rotate the deep groove ball bearing at a uniform speed, ensuring that the outer wall of the deep groove ball bearing is in full and uniform contact with the oil, and complete the oil spraying operation. Step 8: After the oiling is completed, adjust the speed of motor A3 and use centrifugal force to spin dry the deep groove ball bearing. Excess oil will fall into the recycling bin 1 for recycling and reuse. Step 9: After the spin-drying is completed, turn off motor A3, start the electric hydraulic rod 6022 of the fixing component 6 to retract, drive the two clamping plates 601 to move towards each other and retract into the limit ring 5, release the radial fixation of the deep groove ball bearing, start the motor C803 of the lifting component 8 to rotate forward, drive the oil storage tank 701 to move upward to leave clearance space, and the robotic arm extends into the equipment to grab the deep groove ball bearing that has been sprayed with oil and spun dry, and transfer it to the next process to complete a single operation.

[0031] The oil spraying and drying device and its method for using deep groove ball bearings of the present invention have the following advantages: The bearing is precisely positioned circumferentially by the limiting ring 5 on the placement platform 4, and then the fixing component 6 inside the limiting ring 5 drives the two opposing clamping plates 601 to move back and forth by the pushing component 602, so that they extend out from the through grooves A501 on both sides of the limiting ring 5 and clamp the bearing radially, forming a synergistic effect of "circumferential limiting + radial fixing". The heating element 705 inside the oil storage tank 701 is activated to heat the oil to improve its fluidity, while the stirring element 706 stirs the oil to prevent additives from settling and separating. The lowering height of the oil storage tank 701 can be flexibly adjusted by the lifting component 8 to accommodate deep groove ball bearings of different sizes, thus improving the poor adaptability of the existing equipment. The anti-slip texture increases the friction between the clamping plate 601 and the bearing surface, effectively preventing the bearing from sliding relative to the bearing due to centrifugal force during the oil spraying or spin drying process driven by motor A3. This further ensures the synergistic stability of "circumferential limiting + radial fixing", ensuring that the distance between the outer wall of the bearing and the electric nozzle 704 is always consistent, and improving the uniformity of oil application. The output end of motor A3 is detachably connected to the placement table 4 via quick-release assembly 9, which facilitates the quick disassembly and replacement of the appropriate placement table 4 and limiting ring 5 according to the different specifications of the deep groove ball bearings to be processed. This greatly improves the equipment's adaptability to multiple bearing models and meets the processing needs of deep groove ball bearings of different sizes in batch processing.
