Description

Technical Field

[0001] This invention relates to the field of industrial robot technology, and in particular to an integrated industrial robot for automatic feeding and pressing of cylinder head positioning rings. Background Technology

[0002] The cylinder head is a core component of an internal combustion engine, and its assembly precision directly determines the engine's sealing performance, operational stability, and service life. In the cylinder head machining and assembly process, the locating ring is a crucial positioning and assembly component, primarily used to achieve precise alignment and limiting between the cylinder head and the engine block, preventing assembly misalignment and other problems. Before assembly, the locating ring's surface is highly susceptible to the accumulation of impurities such as iron filings, dust, and oil during machining, transportation, and storage. Furthermore, the lack of lubrication between the locating ring and the locating hole makes direct pressing highly prone to causing wear and assembly clearance deviations. Therefore, thoroughly cleaning and evenly applying oil to the locating ring surface before pressing, along with cleaning the cylinder head locating holes, is a necessary step to ensure cylinder head assembly quality and improve product yield. Currently, the industry commonly uses specialized equipment to complete the locating ring loading, cleaning, oiling, and pressing operations, widely applied in the mass production of internal combustion engine cylinder heads.

[0003] Existing traditional positioning ring assembly equipment suffers from numerous shortcomings in practical use, making it difficult to meet the demands of high-precision, automated mass production. Firstly, traditional equipment often employs a split-structure operation, with independent processes for feeding, cleaning positioning holes, cleaning and oiling positioning rings, and pressing. This prevents the formation of an integrated, automated workflow, resulting in cumbersome process connections, significant manual intervention, and low production efficiency. Secondly, traditional cleaning and clamping structures are limited in their cleaning range, only able to clean and oil a single fixed area, leaving numerous cleaning dead zones. This prevents comprehensive cleaning of the positioning ring, leading to poor cleaning and oiling results that directly impact subsequent pressing accuracy. Finally, traditional positioning ring oiling methods often involve manual immersion or sprinkling of oil, resulting in uneven oil adhesion and excessive oil dripping and accumulation. This not only wastes oil and contaminates the equipment and workpiece surfaces but also affects the assembly stability of the positioning rings, reducing the uniformity of product assembly quality. Therefore, this invention proposes an integrated industrial robot for automatic feeding and pressing of cylinder head positioning rings to address the problems existing in the prior art. Summary of the Invention

Simultaneously, the cleaning modules at both ends of the frame clean the cylinder head positioning holes. Finally, the robotic arm aligns and delivers the positioning rings, which are then precisely pressed into place by the pressing assembly.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention achieves automated continuous operation by setting up an integrated structure of a screw feeder, robotic arm, frame, flipping frame, clamping assembly, cleaning and lubrication assembly, cleaning module, and pressing assembly. The screw feeder is responsible for orderly conveying the positioning ring. The frame on the front side of the robotic arm is equipped with a flipping frame and clamping assembly, which can stably clamp the positioning ring and switch the working position to accurately feed the positioning ring into the cleaning and lubrication assembly for comprehensive cleaning and lubrication. At the same time, the cleaning modules at both ends of the frame can simultaneously clean the positioning holes of the cylinder head. Finally, the robotic arm completes the positioning ring alignment and conveying, and the pressing assembly completes the precise pressing. The entire set of equipment integrates multiple processes such as feeding, hole cleaning, positioning ring cleaning and lubrication, and pressing, realizing fully automated operation without manual step-by-step operation, greatly simplifying the production process, and effectively improving the production efficiency and operation continuity of cylinder head positioning ring pressing.

[0018] 2. This invention adopts a switchable clamping component structure, which can realize all-round cleaning and oiling of the positioning ring without dead angles, resulting in a more complete treatment effect. During operation, the positioning ring is first clamped and fixed by two sets of clamping blocks arranged opposite each other. The positioning ring is lifted by flipping the frame, which drives the positioning ring to extend into the cleaning and oiling component to complete the cleaning and oiling operation on one side. After the operation is completed, the two sets of clamping blocks drive the positioning ring to descend and release the positioning ring. The other two sets of clamping blocks take over clamping the positioning ring and extend downward. The positioning ring is lifted again by flipping the frame, so that the uncleaned area of ​​the positioning ring enters the cleaning and oiling component for comprehensive cleaning and oiling of the remaining area of ​​the positioning ring. By using the alternating clamping of the two sets of clamping blocks in the inner cylinder and the flipping frame to change positions, the dead angles of traditional cleaning operations are completely eliminated, ensuring that the entire area of ​​the positioning ring can be cleaned and oiled evenly, thus ensuring the accuracy of subsequent press-fitting and assembly from the source.

[0019] 3. This invention adopts a rotary-fitting precision oiling and cleaning structure, replacing the traditional manual oil immersion method. The operation is cleaner and more energy-efficient. After the positioning ring is delivered into the cleaning and oiling component, the inner cylinder of the clamping component can drive the positioning ring to rotate at a uniform speed. In conjunction with the first telescopic head driving the first cleaning head to fit against the outer side of the positioning ring, all-round cleaning of impurities on the circumference of the positioning ring is achieved. After cleaning, the two sets of air rods drive the jacket to close inward, so that the oil-absorbing cotton on the inner side of the jacket fits tightly against the surface of the positioning ring. The oil can supplies oil to the oil-absorbing cotton through the oil outlet. With the rotation of the positioning ring, the oil-absorbing cotton completes the uniform oiling operation. This fitting micro-oiling method can precisely control the amount of oil applied, and only a uniform oil film is attached to the working surface of the positioning ring. There will be no dripping or oil accumulation problems as in the traditional oil immersion method. It effectively avoids dirt on the workpiece and equipment, saves oil resources, and ensures uniform and stable lubrication effect of the positioning ring, thus improving the product assembly quality.

[0028] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0029] Example 1

[0030] according to Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, this embodiment proposes an integrated industrial robot for automatic feeding and pressing of cylinder head positioning rings. It includes a front-end 1 and a back-end 2. The front-end 1 is equipped with a screw feeder 3. Guide rails 4 are provided on the rear sides of both the front-end 1 and the back-end 2, and a robotic arm 5 moves along the guide rails 4. The back-end 2 is used to place the cylinder head 42 and is equipped with a pressing assembly. The screw feeder 3 is used to transport the positioning rings. A frame 6 is provided on the front side of the robotic arm 5. A flipping frame 7 is provided below and rises and rotates on the inner side of the frame 6. A clamping assembly is provided inside the flipping frame 7. A cleaning and lubrication assembly is provided above the inner side of the frame 6. Cleaning modules are provided at both ends of the frame 6. The clamping assembly is used to clamp the transported positioning rings and switch the cleaning position to send them into the cleaning and lubrication assembly for comprehensive cleaning and lubrication. The cleaning module is used to clean the positioning holes 43 of the cylinder head 42. The robotic arm 5 is used to send the cleaned and lubricated positioning rings into the cleaned positioning holes 43. The pressing assembly performs pressing processing on the positioning rings. The equipment operates in two sections: front-end 1 and back-end 2. Front-end 1 is responsible for the automatic feeding of positioning rings, while back-end 2 is responsible for the positioning and pressing of cylinder heads 42. During operation, the screw feeder 3 continuously and systematically conveys the positioning rings, and the guide rail 4 provides the reciprocating trajectory for the robotic arm 5. The robotic arm 5, equipped with the front frame 6, moves and aligns as a whole. The frame 6 uses a liftable and rotatable flip frame 7 in conjunction with the clamping component to grab the positioning rings and flexibly switch working positions, delivering the positioning rings to the cleaning and lubrication component for full-area cleaning and automatic lubrication. Simultaneously, the cleaning modules at both ends of the frame 6 clean impurities from the positioning holes 43 of the cylinder heads 42 placed in back-end 2, achieving bidirectional cleaning of the positioning rings and positioning holes 43. Finally, the robotic arm 5 precisely places the cleaned positioning rings into the clean positioning holes 43, and, in conjunction with the pressing component in back-end 2, completes the pressing assembly. The entire structure works in tandem to achieve fully automated continuous operation of feeding, cleaning, lubrication, alignment, and pressing, without the need for manual intervention, significantly improving assembly efficiency and continuity.

[0031] The robotic arm 5 has a turntable 8 on its front side, and the frame 6 is rotatably connected to the outside of the turntable 8. A gear 9 is located below the turntable 8, and both ends of the top of the frame 6 are rotatably equipped with first gears 10 that are compatible with the gear 9. Through the gear meshing transmission structure of the turntable 8, gear 9, and first gears 10, the frame 6 is provided with a precise rotation adjustment function. During operation, the gear 9 remains fixed. After the robotic arm 5 controls the turntable 8 to align, the first gear 10 inside the frame 6 meshes and rotates along the circumference of the gear 9, driving the frame 6 to rotate stably as a whole. The horizontal angle of the frame 6 can be flexibly adjusted according to operational needs to adapt to different cleaning, clamping, and alignment conditions, ensuring that the clamping components and cleaning modules mounted on the frame 6 can accurately correspond to the working positions of the positioning ring and the positioning hole 43 of the cylinder head 42, improving the alignment accuracy and adaptability of the equipment.

[0032] The cleaning and refueling assembly includes a connecting frame 11 and processing modules located at both ends inside the connecting frame 11. Each processing module includes an air spring 12, a jacket 13, a first telescopic head 14, and an oil reservoir 16. Two sets of air springs 12 and jackets 13 are provided, with each set of jackets 13 positioned at the output end of one set of air springs 12. A support block is provided on the connecting frame 11 between the two sets of jackets 13. The first telescopic head 14 is located below the support block, and its output end is connected to a first cleaning head 15. Oil-absorbing cotton 17 is provided on the inner side of each jacket 13. The output end of the oil reservoir 16 is connected to the jacket 13 via a conduit, and the inner side of the jacket 13 has an oil outlet hole adapted to the oil-absorbing cotton 17. The cleaning and refueling assembly integrates all components using the connecting frame 11, employing an integrated cleaning and refueling operation mode, replacing traditional manual oil immersion operations. After the positioning ring is inserted into the working area inside the connecting frame 11, the first telescopic head 14 extends downward, driving the first cleaning head 15 to adhere to the outer wall of the positioning ring. Combined with the rotation of the positioning ring, this thoroughly cleans the iron filings, dust, and other impurities from the surface of the positioning ring. After cleaning, the two sets of air rods 12 synchronously drive the jacket 13 to close inward, causing the oil-absorbing cotton 17 inside the jacket 13 to adhere to the surface of the positioning ring. Simultaneously, the oil can 16 delivers a measured amount of oil to the oil-absorbing cotton 17 through the conduit and oil outlet. Combined with the rotation of the positioning ring, the absorbent properties of the oil-absorbing cotton 17 achieve micro-volume, uniform oil application, allowing for precise control of the oil application. This ensures a uniform oil film is formed only on the surface of the positioning ring, completely eliminating the dripping and oil accumulation problems associated with traditional immersion oiling methods. This results in cleaner and more energy-efficient operation while ensuring uniform and stable lubrication of the positioning ring.

[0033] The inner sides of the flipping frame 7 are equipped with first track rods 18 at both ends. Two sets of clamping assemblies are provided, and each set is movably installed on the first track rods 18 at both ends via moving blocks 19. A motor 20 is located below one end of the lifting section of the frame 6, and the output end of the motor 20 is connected to the flipping frame 7. The motor 20 provides the flipping power to the flipping frame 7, driving the frame 7 to flip and reposition stably. This, combined with the lifting action of the frame 6, allows for the adjustment of the positioning ring's height. The two sets of clamping assemblies can slide back and forth along the first track rods 18 via the moving blocks 19, enabling flexible adjustment of the spacing and working position. Through the flipping and lifting of the flipping frame 7, combined with the sliding and repositioning of the two sets of clamping assemblies, the position of the positioning ring can be switched, providing a structural basis for all-round, thorough cleaning and oiling of the positioning ring, as well as for loading and unloading materials, ensuring full-area processing of the positioning ring.

[0034] The clamping assembly includes an outer cylinder 21 and an inner cylinder 22. The outer cylinder 21 is connected to the moving block 19. The inner cylinder 22 is rotatably disposed inside the outer cylinder 21. Both the upper and lower ends of the inner cylinder 22 are provided with edges, and the inner side of the edges is provided with meshing teeth 23. The moving block 19 is rotatably provided with a second gear 24 that matches the meshing teeth 23. Both the upper and lower ends of the inner cylinder 22 are rotatably provided with gear rings 25. The inner side of the inner cylinder 22 is provided with four sets of mounting blocks, and each set of mounting blocks is rotatably provided with a screw rod 26 on its inner side. A sliding rod 27 is fixedly provided. A lifting block 29 is movably provided on the outer side of the screw rod 26 and the sliding rod 27, and the screw rod 26 and the lifting block 29 are threadedly matched. A third gear 28 is rotatably provided above the two sets of mounting blocks and below the other two sets of mounting blocks. The third gear 28 is used to connect with the screw rod 26. The upper third gear 28 is matched with the upper gear ring 25, and the lower third gear 28 is matched with the lower gear ring 25. The clamping assembly adopts a rotatable and adjustable composite transmission structure. During operation, the second gear 24 meshes with the meshing gear 23, which can drive the inner cylinder 22 to rotate as a whole inside the outer cylinder 21, causing the clamped positioning ring to rotate at a uniform speed. With the help of the cleaning and oiling assembly, the positioning ring is cleaned and oiled in all directions around its circumference. Simultaneously, the gear ring 25 drives the third gear 28 to rotate, which in turn drives the screw rod 26 to rotate. Relying on the threaded fit between the screw rod 26 and the lifting block 29, and with the limiting and guiding effect of the slide rod 27, the lifting block 29 is driven to smoothly rise and fall, precisely adjusting the clamping working height. The four sets of mounting blocks are equipped with transmission components in separate areas, ensuring that each pair of clamping functions operates independently and alternately, with precise structural linkage, providing reliable transmission support for the positioning ring to be cleanly repositioned without dead angles and for stable clamping. During equipment operation, two sets of clamping blocks 31, positioned opposite each other, first clamp the fixed positioning ring. The rotating frame 7 then flips and lifts the positioning ring, causing it to extend into the cleaning and lubrication assembly to complete the cleaning and lubrication operation on one side. After the operation is completed, the two sets of clamping blocks 31 lower the positioning ring and release it. Then, two other sets of clamping blocks 31 take over clamping the positioning ring and extend it downwards. The rotating frame 7 then flips and lifts the positioning ring again, allowing the uncleaned area of ​​the positioning ring to enter the cleaning and lubrication assembly for comprehensive cleaning and lubrication of the remaining area of ​​the positioning ring. By using the alternating clamping of the two sets of clamping blocks 31 inside the inner cylinder and the repositioning of the rotating frame 7, the dead corners of traditional cleaning operations are completely eliminated, ensuring that the entire area of ​​the positioning ring can be uniformly and thoroughly cleaned and lubricated, thus guaranteeing the accuracy of subsequent press-fitting and assembly from the source.

[0035] The inner side of the lifting block 29 is equipped with a pneumatic head 30, and the output end of the pneumatic head 30 is connected to a clamping block 31. Two sets of clamping blocks 31 at opposite positions are adapted to clamp the positioning ring. The equipment adopts an alternating clamping operation mode of two sets of clamping blocks 31 to achieve all-round cleaning and oiling of the positioning ring. During operation, after the lifting block 29 is adjusted to the appropriate height, the pneumatic head 30 provides power to drive the clamping blocks 31 to extend and close, and the positioning ring is clamped and fixed by the cooperation of the two sets of clamping blocks 31. After the first clamping is completed, the flipping frame 7 flips and lifts the positioning ring to complete the cleaning and oiling; then the clamping block 31 releases the positioning ring and lowers, and another set of clamping blocks 31 takes over to clamp the positioning ring and adjusts its posture, and lifts the alignment cleaning and oiling component again to perform secondary cleaning and oiling of the untreated areas of the positioning ring. By alternating clamping, cleaning dead corners are completely avoided, making the overall cleaning and oiling effect of the positioning ring more uniform and perfect.

[0036] The cleaning module includes a side arm 32 and a lifting rod 33. The side arm 32 is connected to the frame 6. The lifting rod 33 is located below the side arm 32. The output end of the lifting rod 33 is connected to a telescopic plate 34, and an air pump 35 is located below the telescopic plate 34. A bottom head 36 is located below the output end of the telescopic plate 34, and a nozzle 37 and a second telescopic head 38 are located below the bottom head 36. The output end of the air pump 35 is connected to the nozzle 37 through a conduit. A second cleaning head 39 is rotatably connected to the output end of the second telescopic head 38. The cleaning module is used for specialized cleaning of the positioning hole 43 of the cylinder head 42. During operation, the side arm 32 provides fixed support, and the lifting rod 33 drives the telescopic plate 34 to rise and fall as a whole for alignment, so that the bottom cleaning structure is aligned with the positioning hole 43. The air pump 35 generates a high-pressure airflow, which is delivered to the nozzle 37 through a conduit and ejected to blow away dust and iron filings inside the positioning hole 43. Simultaneously, the second telescopic head 38 drives the second cleaning head 39 to extend into the positioning hole 43 and rotate to deeply wipe away residual impurities on the hole wall. The bottom head 36 serves a structural integration and protective function. Through this dual cleaning method of high-pressure blowing and mechanical wiping, impurities inside the positioning hole 43 are thoroughly cleaned, preventing residual impurities from affecting the subsequent positioning ring pressing accuracy and ensuring assembly fit precision.

[0037] Example 2

[0038] according to Figure 1 , 2As shown in Figures 3, 4, 5, 6, and 7, this embodiment proposes an integrated industrial robot for automatic feeding and pressing of cylinder head positioning rings. It includes a front-end 1 and a back-end 2. The front-end 1 is equipped with a screw feeder 3. Guide rails 4 are provided on the rear sides of both the front-end 1 and the back-end 2, and a robotic arm 5 moves along the guide rails 4. The back-end 2 is used to place the cylinder head 42 and is equipped with a pressing assembly. The screw feeder 3 is used to transport the positioning rings. A frame 6 is provided on the front side of the robotic arm 5. A flipping frame 7 is provided below and rises and rotates on the inner side of the frame 6. A clamping assembly is provided inside the flipping frame 7. A cleaning and lubrication assembly is provided above the inner side of the frame 6. Cleaning modules are provided at both ends of the frame 6. The clamping assembly is used to clamp the transported positioning rings and switch the cleaning position to send them into the cleaning and lubrication assembly for comprehensive cleaning and lubrication. The cleaning module is used to clean the positioning holes 43 of the cylinder head 42. The robotic arm 5 is used to send the cleaned and lubricated positioning rings into the cleaned positioning holes 43. The pressing assembly performs pressing processing on the positioning rings. The equipment operates in two sections: front-end 1 and back-end 2. Front-end 1 is responsible for the automatic feeding of positioning rings, while back-end 2 is responsible for the positioning and pressing of cylinder heads 42. During operation, the screw feeder 3 continuously and systematically conveys the positioning rings, and the guide rail 4 provides the reciprocating trajectory for the robotic arm 5. The robotic arm 5, equipped with the front frame 6, moves and aligns as a whole. The frame 6 uses a liftable and rotatable flip frame 7 in conjunction with the clamping component to grab the positioning rings and flexibly switch working positions, delivering the positioning rings to the cleaning and lubrication component for full-area cleaning and automatic lubrication. Simultaneously, the cleaning modules at both ends of the frame 6 clean impurities from the positioning holes 43 of the cylinder heads 42 placed in back-end 2, achieving bidirectional cleaning of the positioning rings and positioning holes 43. Finally, the robotic arm 5 precisely places the cleaned positioning rings into the clean positioning holes 43, and, in conjunction with the pressing component in back-end 2, completes the pressing assembly. The entire structure works in tandem to achieve fully automated continuous operation of feeding, cleaning, lubrication, alignment, and pressing, without the need for manual intervention, significantly improving assembly efficiency and continuity.

[0039] The backstage 2 is equipped with a platform 40, and a support head 41 is located on top of the platform 40. The cylinder head 42 is placed above the support head 41. The backstage 2 achieves flat support of the working plane through the platform 40, and the support head 41 on top of the platform 40 provides fixed-point support and limitation for the cylinder head 42, which can stably support the cylinder head 42 and limit the displacement and shaking of the cylinder head 42 during operation. During the cleaning of the positioning hole 43 and the pressing of the positioning ring, the cylinder head 42 is always kept in a fixed posture and in a precise position, avoiding problems such as incomplete cleaning and misalignment due to workpiece displacement, thus providing a stable tooling foundation for subsequent precise assembly operations.

[0040] The backstage 2 has second track rods 44 on both sides, and a platform 45 is movably mounted on the second track rods 44. The pressing assembly is mounted on the platform 45 and includes a pressing frame 46 and a pressure cylinder 47. The pressure cylinder 47 is located above the pressing frame 46, and a pressure plate 48 is provided at the output end of the pressure cylinder 47. The pressure plate 48 is used to press the positioning ring. The pressing assembly can be horizontally adjusted along the second track rods 44 via the platform 45, flexibly adapting to the positioning hole 43 positions of cylinder heads 42 of different specifications, thus improving its adaptability. The pressure frame 46 provides a fixed support for the overall pressing structure. During operation, after the positioning ring is accurately inserted into the positioning hole 43, the pressure cylinder 47 is activated, driving the pressure plate 48 to move downward smoothly, applying uniform and stable pressure to the positioning ring, and accurately pressing the positioning ring into the positioning hole 43, completing the fastening assembly of the positioning ring and the cylinder head 42. The pressing force is uniform and controllable, effectively avoiding problems such as pressing too loosely, too tightly, or offset.

[0041] Both ends of the pressure plate 48 are equipped with guide plates, and both ends of the pressure frame 46 are equipped with guide rods 49. The pressure plate 48 is slidably connected to the guide rods 49. When the pressure plate 48 is pressed down, the sliding cooperation between the guide plates and the guide rods 49 at both ends achieves limiting guidance, restricting the horizontal offset of the pressure plate 48, and ensuring that the pressure plate 48 always moves vertically and smoothly up and down. This effectively prevents tilting or offset during the pressing process of the pressure plate 48, ensuring uniform pressure during pressing, further improving the coaxiality and assembly accuracy of the positioning ring pressing, ensuring the consistency and stability of each pressing operation, and improving the overall assembly quality of the product.

[0042] This integrated industrial robot for automatic feeding and pressing of cylinder head positioning rings achieves automated continuous operation through an integrated structure consisting of a screw feeder 3, a robotic arm 5, a frame 6, a flipping frame 7, a clamping assembly, a cleaning and lubrication assembly, a cleaning module, and a pressing assembly. The screw feeder 3 is responsible for the orderly conveying of the positioning rings. The frame 6 on the front side of the robotic arm 5 carries the flipping frame 7 and the clamping assembly, which can stably hold the positioning rings and switch the working position to accurately feed the positioning rings into the cleaning and lubrication assembly for comprehensive cleaning and lubrication. At the same time, the cleaning modules at both ends of the frame 6 can simultaneously clean the positioning holes 43 of the cylinder head 42. Finally, the robotic arm 5 completes the alignment and conveying of the positioning rings, and the pressing assembly completes the precise pressing. The entire set of equipment integrates multiple processes such as feeding, hole cleaning, positioning ring cleaning and lubrication, and pressing, achieving fully automated operation without the need for manual step-by-step operation, greatly simplifying the production process and effectively improving the production efficiency and operational continuity of cylinder head positioning ring pressing. This invention employs a switchable clamping assembly structure, enabling comprehensive cleaning and oiling of the positioning ring without any blind spots. The processing effect is more complete. During operation, two sets of clamping blocks 31, positioned opposite each other, first clamp the fixed positioning ring. The rotating frame 7 then flips and lifts the positioning ring, allowing it to extend into the cleaning and oiling assembly to complete cleaning and oiling on one side. After completion, the two sets of clamping blocks 31 lower and release the positioning ring, allowing two other sets of clamping blocks 31 to take over clamping and extending downwards. The rotating frame 7 then flips and lifts the positioning ring again, allowing the uncleaned areas to enter the cleaning and oiling assembly for comprehensive cleaning and oiling of the remaining areas. By alternating clamping with two sets of clamping blocks 31 inside the inner cylinder and rotating the frame 7, the dead spots of traditional cleaning operations are completely eliminated, ensuring that the entire positioning ring receives uniform and thorough cleaning and oiling, thus guaranteeing the accuracy of subsequent press-fitting and assembly from the source. This invention employs a rotary-fitting precision oiling and cleaning structure, replacing the traditional manual oil immersion method. This results in cleaner and more energy-efficient operation. After the positioning ring is delivered into the cleaning and oiling assembly, the inner cylinder 22 of the clamping assembly drives the positioning ring to rotate at a constant speed. This, combined with the first telescopic head 14 driving the first cleaning head 15 to fit against the outer side of the positioning ring, achieves all-round cleaning of impurities on the circumference of the positioning ring. After cleaning, the two sets of air rods 12 drive the jacket 13 to close inward, so that the oil-absorbing cotton 17 on the inner side of the jacket 13 tightly fits against the surface of the positioning ring. The oil can 16 supplies a quantitative amount of oil to the oil-absorbing cotton 17 through the oil outlet. With the rotation of the positioning ring, the oil-absorbing cotton 17 completes the uniform oiling operation. This fitting micro-oiling method can precisely control the amount of oil applied, ensuring that only a uniform oil film adheres to the working surface of the positioning ring. It avoids the dripping and oil accumulation problems of the traditional oil immersion method, effectively preventing dirt from the workpiece and equipment, saving oil resources, ensuring uniform and stable lubrication of the positioning ring, and improving the product assembly quality.
