Abstract
Description
Technical Field
[0001] This invention relates to the field of workpiece surface treatment technology, and in particular to an oiling method and an oiling apparatus. Background Technology
[0002] Currently, the components involved in miniature reducers are mostly small, precision parts with similar processing techniques, small demand for each type, and all parts require uniform anti-rust and oiling treatment after processing. If multiple dedicated production lines are used to process and oil different parts separately, it can easily lead to problems such as low equipment utilization, high production costs, and large floor space requirements, resulting in poor overall production efficiency and economy. Therefore, it is not suitable for a multi-variety, small-batch production model.
[0003] Based on the aforementioned production needs, a flexible mixed-line production method is more reasonable. However, in a unified oiling process, different specifications and structures of parts have different requirements in terms of oiling position, oiling amount, oiling range, and oiling precision. Traditional oiling fixtures and methods cannot simultaneously meet the needs of rapid switching and precise oiling of multiple parts, which can easily lead to problems such as uneven oiling, missed coating, overcoating, or poor compatibility, thereby affecting the assembly performance and service life of miniature reducer parts.
[0004] Therefore, how to design an oiling device with a reasonable structure, strong versatility, convenient switching and high oiling precision to meet the needs of multi-variety, small-batch, and flexible mixed-line production of micro reducers has become a technical problem that urgently needs to be solved in this field.

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0054] In the flexible mixed-line production of micro reducers with multiple varieties and small batches, there are significant differences in the oiling position, oiling amount, oiling range and oiling precision of different specifications of parts. Traditional oiling fixtures are difficult to switch quickly and adapt accurately, resulting in uneven oiling, missed coating or over-coating. Among them, the deviation of the oiling position directly affects the uniformity of the lubricating film on the surface of the parts. Furthermore, the inaccurate control of the oiling amount causes local oil film to be too thick or insufficient, which leads to abnormal fluctuations in frictional resistance during assembly, and thus has an adverse effect on the operational stability and long-term reliability of the micro reducer.
[0055] If the above problems are not effectively resolved, the compatibility defects of the oiling process will continue to restrict the continuity of flexible mixed-line production. In particular, the instability of the lubrication state of the parts surface caused by uneven oiling will directly lead to abnormal vibration and noise in the micro reducer in the early stage of operation. Furthermore, the lack of effective oil film protection in the uncoated areas will accelerate the accumulation of micro damage, and the oil residue in the overcoated areas will cause impurities to be adsorbed, thereby significantly reducing the fitting accuracy and motion coordination of the parts. Ultimately, this will reduce the overall assembly qualification rate and shorten the service life. The increased frequency of production interruptions will further weaken the overall efficiency of the equipment.
[0056] In this regard, combined with Figures 1 to 3 as well as Figure 6 This embodiment proposes an oiling method, including the following steps:
[0057] S1. Lubricating oil is loaded into the oil storage mechanism 701. The oil storage mechanism 701 is connected to the oil outlet block 40 through the adjusting base 30 via the conduit. The adjusting base 30 and the oil outlet block 40 are attracted by the magnetic element 80. The oil outlet 400 is provided with an applicator head 50 at the oil outlet nozzle 403. The adjusting base 30 is installed on the adjusting mechanism. Under the action of gravity, the lubricating oil is transported from the oil storage mechanism 701 through the conduit and the adjusting base 30 to the oil outlet nozzle 403 of the oil outlet block 40, so that the applicator head 50 outside the oil outlet nozzle 403 is filled with lubricating oil.
[0058] S2. Move the first specification part to be oiled to the oil outlet 403 of a set of adjusting bases 30 so that the part to be oiled comes into contact with the coating head 50. The lubricating oil in the coating head 50 is evenly transferred to the surface of the first specification part to complete the oiling operation of the first specification part.
[0059] S3. When switching to oiling the second or other different specification parts, select an oil outlet block 40 that matches the structure of the part to be oiled according to the external dimensions of the part to be oiled, remove the oil outlet block 40 in step S2 and replace the oil outlet block 40; adjust the adjustment mechanism according to the oiling position and oiling angle of the part to be oiled, so that the adjustment base 30 moves in at least one direction of horizontal direction, vertical direction and angle deflection, thereby adjusting the position of the oil outlet block 40 and the applicator head 50, so that the posture of the oil outlet block 40 and the applicator head 50 matches the structure of the part to be oiled, so that the part to be oiled contacts the applicator head 50, and the lubricating oil in the applicator head 50 is evenly transferred to the surface of the second or other different specification parts, thus completing the oiling operation of the second or other different specification parts.
[0060] S4. Repeat step S3 to continuously apply oil to parts of different specifications.
[0061] For ease of understanding, the following explains some key terms in this embodiment:
[0062] The oil storage mechanism 701 is designed to store the lubricating oil to be coated. This mechanism typically includes a container holding the lubricating oil and a conduit to deliver the lubricating oil to the oiling system.
[0063] The adjusting base 30 is a core component of the oiling system. It is mounted on the adjusting mechanism and supports the oil outlet block 40. The base has internal flow channels to guide the lubricating oil from the conduit to the oil outlet block 40.
[0064] The oil dispensing block 40 is a component directly connected to the applicator head 50, and it has an oil dispensing nozzle 403 inside. The oil dispensing block 40 is detachably connected to the adjustment base 30 via a magnetic element 80, which facilitates quick replacement.
[0065] Magnetic element 80 is used to achieve rapid adsorption and separation between the regulating base 30 and the oil outlet block 40. This element is typically made of permanent magnets, providing a stable adsorption force. Figure 14 and Figure 15 The magnetic element 80 is a ring element, that is, the magnetic element 80 has a second connecting channel 801, and the conduit connecting the oil storage mechanism 701 and the oil outlet block 40 passes through the second connecting channel 801.
[0066] The applicator head 50 is located at the oil outlet 403 of the oil outlet block 40 and is the component that directly contacts the part to be oiled. The applicator head 50 is designed to absorb and evenly release lubricating oil to achieve coating on the surface of the part.
[0067] The adjustment mechanism is a device used to drive the adjustment base 30 to adjust its position and orientation. This mechanism enables the adjustment base 30 to be tilted horizontally, vertically, or at an angle to accommodate the oiling requirements of parts of different sizes.
[0068] The conduit is a channel connecting the oil storage mechanism 701, the adjusting base 30, and the oil outlet block 40, and is used to transport lubricating oil.
[0069] The oil outlet 403 is an opening on the oil outlet block 40 through which lubricating oil flows out and wets the applicator head 50.
[0070] This embodiment provides an oiling method, which is characterized by the following aspects:
[0071] First, in step S1, lubricating oil is loaded into the oil storage mechanism 701. The oil storage mechanism 701 is connected to the adjusting base 30 via a conduit, and the adjusting base 30 is in turn connected to the oil outlet block 40. The adjusting base 30 and the oil outlet block 40 are connected by magnetic element 80. An applicator head 50 is provided at the oil outlet nozzle 403 of the oil outlet block 40. The adjusting base 30 is mounted on the adjusting mechanism. Under the action of gravity, the lubricating oil can be transported from the oil storage mechanism 701 through the conduit and the adjusting base 30 to the oil outlet nozzle 403 of the oil outlet block 40, thereby filling the applicator head 50 outside the oil outlet nozzle 403 with lubricating oil. For example, the oil storage mechanism 701 can be a simple oil tank, which transports the lubricating oil to the adjusting base 30 by gravity or pumping. The adjusting base 30 and the oil outlet block 40 can also be magnetically attached for easy disassembly. The applicator head 50 is fixed to the outside of the oil outlet nozzle 403.
[0072] Secondly, in step S2, the first specification part to be oiled is moved between the oil outlets 403 of a set of adjusting bases 30. The part to be oiled comes into contact with the coating head 50, and the lubricating oil in the coating head 50 is evenly transferred to the surface of the first specification part, completing the oiling operation of the first specification part.
[0073] Further, in step S3, when it is necessary to switch to oiling a second or other different specification part, an oil outlet block 40 matching the structure of the part to be oiled needs to be selected according to the external dimensions of the part. The original oil outlet block 40 is removed and replaced with a new one. Simultaneously, according to the oiling position and angle of the part to be oiled, the adjustment mechanism is operated, causing the adjustment base 30 to move in at least one direction: horizontal, vertical, or angular deflection. Thus, the positions of the oil outlet block 40 and the applicator head 50 are adjusted to match the structure of the part to be oiled. Subsequently, the part to be oiled contacts the applicator head 50, and the lubricating oil in the applicator head 50 is evenly transferred to the surface of the second or other different specification part, completing the oiling operation for the second or other different specification part. For example, the oil outlet block 40 can be pre-prepared in various shapes and sizes to meet the oiling needs of different parts. The adjustment mechanism can use a manual adjustment screw or a simple gear transmission mechanism to realize the movement and rotation of the adjustment base 30.
[0074] Finally, in step S4, step S3 is repeated to sequentially apply oil to parts of different specifications. This means that, through the aforementioned switchable and adjustable mechanism, this oiling method can adapt to the production needs of multiple varieties and small batches, enabling rapid switching and continuous oiling operations for parts of different specifications.
[0075] The following example will provide a more detailed explanation of the above technical solution:
[0076] Imagine a miniature gear reducer manufacturing workshop where various gears of different specifications require rust-proofing and oiling. These gears vary in size and the locations of the surfaces requiring oiling.
[0077] First, before the oiling operation begins, the operator fills the oil reservoir 701 with rust-preventive lubricating oil. This reservoir 701 is connected to the adjusting base 30 via a conduit. Under gravity, the lubricating oil flows through the conduit into the adjusting base 30 and then into the oil outlet block 40, which is adsorbed and connected to the adjusting base 30. An applicator head 50 is located at the oil outlet nozzle 403 of the oil outlet block 40. The lubricating oil continuously wets the applicator head 50, keeping it moist.
[0078] When the first batch of gears of the first specification needs to be oiled, the gears are conveyed to the oiling station. An oiling area is formed between the oil outlets 403 of a set of adjusting bases 30. The part of the first specification gear to be oiled is moved to contact the coating head 50. Due to the gear's own weight or a slight external pressure, the gear exerts a force on the coating head 50. When the coating head 50 is under pressure, the lubricating oil stored inside is evenly squeezed and transferred to the surface of the first specification gear, thereby completing the oiling operation for this batch of gears.
[0079] Subsequently, the production line needs to switch to the second batch of gears of the second specification for oiling. The diameter and oiling location of these second-specification gears differ significantly from those of the first-specification gears. At this point, the operator first selects an oiling block 40 from a variety of prepared oiling blocks 40 that matches the structure of the second-specification gear, based on the gear's dimensions and oiling requirements. Since the adjusting base 30 and the oiling block 40 are magnetically connected, the operator can easily remove the old oiling block 40 and quickly replace it with a new one. Next, to ensure the applicator head 50 accurately contacts the oiling area of the second-specification gear, the operator adjusts the adjusting base 30 using the adjusting mechanism. For example, the adjusting mechanism can drive the adjusting base 30 to move horizontally to accommodate gears of different diameters; or it can drive the adjusting base 30 to deflect at an angle to accommodate oiling on inclined surfaces. Through these adjustments, the overall posture of the oiling block 40 and the applicator head 50 is precisely matched to the structure of the second-specification gear. Then, the second-specification gear is moved to contact the adjusted applicator head 50 and pressure is applied, and the lubricant is once again evenly transferred to the gear surface, completing the oiling operation of the second-specification gear.
[0080] This method can be repeated, meaning step S3 is repeated to sequentially apply oil to the third, fourth, or other gears of different specifications. In this way, the oiling method can flexibly meet the production needs of diverse products in small batches, enabling rapid switching between different parts specifications and efficient oiling.
[0081] It should be noted that the applicator head 50 in the above example is one of a sponge, wool felt, or oil-absorbing cotton. In this embodiment, the applicator head 50 is a key component that directly contacts the part to be oiled and is responsible for transferring the lubricating oil from the oil outlet 403 to the surface of the part. The choice of its material directly affects the absorption, storage, and release performance of the lubricating oil, as well as its adaptability to the surface shape of the part. Among them, a sponge is a material with an open or closed porous structure, which can quickly absorb and store a large amount of liquid through capillary action. Its elasticity allows it to release the stored liquid when compressed and return to its original shape after the pressure is released, thereby achieving effective transfer of lubricating oil. The porosity and density of the sponge can be adjusted according to the required oil absorption and release characteristics. Wool felt is a non-woven fabric made of wool fibers interwoven and compressed by mechanical or chemical methods. Its unique fiber structure gives it excellent oil absorption and oil retention properties, can evenly distribute lubricating oil, and has a certain degree of wear resistance, making it suitable for occasions requiring stable and uniform oiling. Oil-absorbing cotton is a material specially designed for efficient absorption of oily substances, usually made of hydrophobic and oleophilic fibers such as polypropylene. It possesses an extremely high oil absorption rate and excellent oil retention capacity, enabling precise control of the lubricant supply to avoid over-applying oil while maintaining the cleanliness of the applicator head 50. This embodiment limits the material of the applicator head 50 to one of the following: sponge, wool felt, or absorbent cotton. This allows the applicator head 50 to efficiently absorb and fully saturate the lubricant in step S1. These materials, with their unique porous structure or interwoven fiber characteristics, can form abundant oil storage spaces, ensuring that the lubricant can be effectively trapped and retained. In steps S2 and S3, when the part to be oiled comes into contact with the applicator head 50 and pressure is applied, the elasticity or fiber structure of the applicator head 50 deforms under pressure, causing the internally stored lubricant to be uniformly transferred to the surface of the part in a controlled manner. This material characteristic ensures a stable supply and uniform application of lubricant, avoiding problems such as uneven oil distribution or low oiling efficiency caused by poor material of the applicator head 50. At the same time, these materials also have a certain degree of wear resistance and resilience, which can adapt to repeated contact and pressure application of parts of different specifications, ensuring the continuity and consistency of the oiling operation.
[0082] Based on the above examples, the oiling method of this embodiment demonstrates a significant technical contribution in solving the aforementioned technical problems.
[0083] Traditional oiling methods often rely on fixed-size oiling fixtures or single oiling equipment, which are difficult to adapt to the oiling needs of parts of different specifications. This results in low equipment utilization and poor switching efficiency in multi-variety, small-batch production modes, and problems such as uneven oiling and missed coating are prone to occur.
[0084] This embodiment effectively solves the aforementioned problems by introducing a quickly replaceable oil outlet block 40 and a flexibly adjustable adjustment mechanism. Specifically, the application of the magnetic element 80 makes the replacement process of the oil outlet block 40 extremely convenient, significantly shortening the changeover time compared to the traditional bolt fixing method. Furthermore, the adjustment mechanism allows for precise adjustment of the adjustment base 30 in multiple directions, including horizontal, vertical, and angular deflection, ensuring that the posture of the applicator head 50 always matches the structure of the part to be oiled. This flexibility allows the method to be compatible with parts of various specifications and structures, avoiding the cumbersome and costly process of designing dedicated oiling fixtures for each part.
[0085] Therefore, this oiling method enables rapid switching and precise oiling of parts with different specifications, significantly improving the flexibility of the production line and overall production efficiency. Its strong versatility, convenient switching, and high oiling precision allow it to effectively adapt to the needs of multi-variety, small-batch, and flexible mixed-line production of micro reducers, providing a rationally structured and efficient oiling solution for the field.
[0086] Combination Figures 3 to 5 In this embodiment, it is further proposed that in steps S2 to S4, excess oil on the applicator head 50 is transported to the oil collection mechanism 702 through the oil outlet hole 304 opened on the adjusting base 30 via a conduit to achieve oil recovery.
[0087] Excess oil spillage on the applicator head 50 refers to lubricating oil that fails to be completely transferred to the surface of the part during the oiling process and remains on or near the surface of the applicator head 50. This spillage can be caused by various factors such as excessive oil application, irregular part surfaces, and uneven contact pressure between the applicator head 50 and the part. The oil spillage outlet 304 on the adjusting base 30 is a channel specifically designed to collect and drain the spillage. This outlet 304 can be a simple circular or rectangular hole, a channel with a certain angle of inclination, or an annular collection groove that matches the shape of the bottom of the applicator head 50 to ensure smooth flow of the spillage. The conduit is a flexible or rigid pipe used to transport the spillage collected from the outlet 304 to the oil spillage collection mechanism 702. The oil spillage collection mechanism 702 is a device for receiving, storing, and / or treating spillage. It can be a simple open container, such as a plastic bucket or metal box, or a closed oil tank with a level sensor, filter, or pumping device for preliminary filtration or further treatment of the recovered spilled oil. Achieving spilled oil recovery refers to collecting excess lubricating oil generated during the oiling process through the aforementioned structure and process, thereby conserving resources, reducing waste, and protecting the environment.
[0088] This embodiment further proposes that in the above-mentioned oiling method, the solid oil residue collected by the adjusting base 30 is discharged through the solid oil residue discharge hole 305 opened at the bottom of the adjusting base 30.
[0089] The solid oil sludge collected by the regulating base 30 refers to solid or semi-solid deposits formed inside or near the regulating base 30 during the process of lubricating oil being transported from the oil storage mechanism 701 to the oil outlet block 40, due to factors such as lubricating oil degradation, contact with air, or impurities introduced through contact with parts. These solid oil sludge deposits are typically denser than the lubricating oil itself and will gradually settle under gravity. The internal structure of the regulating base 30 can be designed with specific flow channels or settling areas to promote the aggregation and collection of these solid oil sludge deposits. For example, the internal channels of the regulating base 30 can be designed with slight depressions or slopes to guide the solid oil sludge to converge in specific areas; or, the material surface of the regulating base 30 can be specially treated to reduce the adhesion of solid oil sludge, making it easier for it to move to the collection area under the action of fluid. The solid oil sludge discharge hole 305 at the bottom of the regulating base 30 refers to one or more openings provided at the lower part or lowest point of the regulating base 30 for discharging solid oil sludge. The solid oil residue discharge hole 305 can be circular, elliptical, rectangular, or slit-shaped, and its size should be sufficient to allow solid oil residue to pass through smoothly without easily clogging. For example, the solid oil residue discharge hole 305 can be a simple straight hole or a channel with a conical or flared design to facilitate the discharge of solid oil residue. Discharge refers to the process of removing the collected solid oil residue from the adjusting base 30 through the solid oil residue discharge hole 305. This discharge can be passive discharge relying on gravity, i.e., the solid oil residue flows out of the solid oil residue discharge hole 305 under its own gravity; or it can be auxiliary active discharge, such as using mechanical means such as periodic vibration or slight pressure pulses to force the solid oil residue to be discharged from the solid oil residue discharge hole 305.
[0090] This embodiment incorporates a solid oil residue discharge hole 305 at the bottom of the adjusting base 30. This allows solid oil residue generated during the oiling process to settle and accumulate at the bottom of the adjusting base 30 under gravity, and then be effectively discharged through the discharge hole 305. This parallels the main path of lubricating oil being transported via a conduit through the adjusting base 30 to the oil outlet 403 of the oil outlet block 40, ensuring the applicator head 50 is fully saturated with lubricating oil, thus forming an independent solid oil residue management loop. As the lubricating oil flows within the adjusting base 30, any solid impurities or degradation products carried within it gradually settle due to density differences. The bottom design of the adjusting base 30, combined with the solid oil residue discharge hole 305, ensures that this settled solid oil residue is guided to the discharge hole 305 and discharged from the system. This design ensures that the lubricating oil maintains a high level of cleanliness before reaching the applicator head 50, avoiding negative impacts of solid oil residue on oiling quality and device operation. In this way, the oiling method of this embodiment achieves efficient oiling while effectively solving the pollution and clogging problems caused by the accumulation of solid oil residue, thereby improving the reliability and maintenance convenience of the entire oiling system.
[0091] This embodiment further proposes that the solid oil residue discharge hole 305 discharges the solid oil residue to the solid oil residue collection mechanism 703.
[0092] The solid oil residue discharge port 305 is a channel at the bottom of the adjusting base 30 for discharging solid oil residue. The discharged solid oil residue is guided to the solid oil residue collection mechanism 703 for centralized collection and management. The solid oil residue collection mechanism 703 can be a separate container, such as an oil collection tank, a collection box with a filter screen, or a pipe interface connected to a centralized treatment system. Its function is to prevent solid oil residue from scattering randomly, maintain a clean working environment, and facilitate subsequent unified treatment or recycling.
[0093] This embodiment further proposes the above-mentioned oiling method for housing / end-cap type parts of harmonic reducers. Because these parts have complex cavities, multi-step holes, and numerous mounting surfaces, uniform rust prevention and no dead corners are required for the inner cavity and threaded holes. Therefore, it combines... Figure 9 and Figure 10 The applicator head 50 includes a ball-joint adjustable spray bar 501, a main nozzle 502 connected to the outlet of the ball-joint adjustable spray bar 501 and extending a preset distance along the length of the oil outlet block 40, and multiple auxiliary nozzles 503 connected to the main nozzle 502. The main nozzle 502 provides overall oil supply, and together with the multiple auxiliary nozzles 503, it enables simultaneous oiling of large external surfaces and deep internal holes. Meanwhile, the angle of the ball-joint adjustable spray bar 501 is omnidirectionally adjustable, allowing it to reach into deep cavities, stepped holes, and threaded holes of parts, ensuring thorough coating in hard-to-reach areas.
[0094] For the wave generator cam component of the harmonic reducer, its characteristics include an eccentric / elliptical profile (not a perfect circle), a high-precision journal, and a journal that is a precision mating surface requiring only localized, precise lubrication. Therefore, combined with... Figure 11 The applicator head 50 includes a set of semi-annular retaining arms 504 symmetrically arranged along the central axis of the oil outlet block 40 and nozzles 505 disposed on the semi-annular retaining arms 504. The nozzles 505 disposed on the semi-annular retaining arms 504 can only apply the journal.
[0095] For the rigid wheel component of the harmonic reducer, the rigid wheel is a rigid ring-shaped part with teeth on both the inner and outer sides. The inner hole, outer teeth, inner teeth, and end face of the rigid wheel all need to be coated simultaneously. Therefore, combined with... Figure 12 The applicator head 50 is a fan-shaped nozzle 506; the fan-shaped nozzle 506 has a large coverage area, ensuring full coverage and no missed areas.
[0096] For the flex wheel component of the harmonic reducer, the flex wheel has a cup-shaped inner cavity; therefore, in combination with... Figure 13 The applicator head 50 is a cup-shaped nozzle 507; the cup-shaped nozzle 507 ensures a consistent oil film thickness, preventing areas from having too much oil or too little oil.
[0097] This embodiment further proposes that in the above-mentioned oiling method, the adjustment mechanism drives the adjustment base 30 to move linearly in the horizontal direction, and the adjustment range covers the oiling positions of at least three different specifications of parts.
[0098] The adjustment mechanism is an actuator used to change the spatial position and orientation of the adjustment base 30. It drives the adjustment base 30 to move linearly in the horizontal direction, meaning the adjustment base 30 can perform linear displacement on a horizontal plane. This linear movement can be achieved in various ways; for example, it can use a ball screw and linear guide structure, with a stepper motor or servo motor driving the ball screw 601 to rotate, thereby moving the adjustment base 30 connected to the slider along the guide direction. The adjustment range refers to the maximum distance the adjustment mechanism can move the adjustment base 30 in the horizontal direction. Covering the oiling positions of at least three different sizes of parts means that the linear movement capability of the adjustment mechanism is sufficient to allow the applicator head 50 to accurately align with the oiling areas of at least three different sizes or shapes of parts. This ensures that, without changing the hardware of the adjustment mechanism, it can quickly adapt to various production needs through simple operation.
[0099] In this embodiment, the adjusting mechanism drives the adjusting base 30 to move linearly in the horizontal direction, enabling the adjusting base 30 and the oiling block 40 and applicator head 50 connected to it to quickly and accurately reach the preset oiling position. By pre-setting the oiling positions for different parts, the adjusting mechanism can automatically or semi-automatically adjust the applicator head 50 to a horizontal position that matches the oiling area of the part, based on the current specifications of the part to be oiled. This adjustment capability ensures that the applicator head 50 can cover the oiling positions of at least three different parts, thereby avoiding frequent manual adjustments or tooling changes and significantly improving the efficiency and accuracy when switching between different parts.
[0100] This embodiment further proposes the above-mentioned oiling method, wherein the adjustment mechanism drives the adjustment base 30 to rotate, so that the tilt angle of the adjustment base 30 is continuously adjustable within the range of 0°-90°.
[0101] The adjustment mechanism drives the adjustment base 30 to rotate, meaning that the adjustment base 30 rotates around its own axis or a specific rotation axis mechanically, thereby changing its spatial posture. This drive can be achieved through a stepper motor or servo motor in conjunction with a gear transmission mechanism, converting the motor's rotational motion into precise angular rotation of the adjustment base 30. The tilt angle is continuously adjustable within the range of 0°-90°, meaning that the angle between the adjustment base 30 and a reference plane (e.g., a horizontal plane) can be set and maintained at any value between 0 and 90 degrees, rather than being limited to a few discrete angles. This can be achieved by an encoder working in conjunction with the drive mechanism to provide real-time feedback on the actual angle of the adjustment base 30, and by a controller performing closed-loop control to ensure the continuity and accuracy of the angle.
[0102] This embodiment uses an adjustment mechanism to drive the adjustment base 30 to rotate, allowing its tilt angle to be continuously adjusted within the range of 0°-90°. This greatly enhances the adaptability of the oiling device to parts of different specifications and shapes. In the above oiling method, the adjustment mechanism already has the ability to adjust the horizontal direction, vertical direction, and angular deflection of the adjustment base 30. Building upon this, by providing the adjustment base 30 with a continuously adjustable tilt angle, the applicator head 50 can match the surface of the part to be oiled with a more precise and accurate posture. For example, for parts with steep slopes or complex curved surfaces, traditional discrete angle adjustments may not achieve optimal contact, leading to uneven oiling. This solution, with its continuously adjustable range of 0°-90°, ensures that the applicator head 50 always maintains the most ideal contact angle with the part surface, thereby guaranteeing uniform oil transfer. This precise posture adjustment capability, combined with the original position adjustment capability, forms a more complete and flexible oiling system, effectively solving the oiling quality problem caused by insufficient angle matching and significantly improving the accuracy and efficiency of oiling operations.
[0103] This embodiment also proposes an oiling device to solve the technical problems of poor versatility and low switching efficiency of oiling devices in the production of various types and small batches of micro reducers.
[0104] Combination Figures 1 to 8 The device includes a base 10 with an adjustment mechanism comprising a height adjustment mechanism 20 and a position / attitude adjustment mechanism 60. The height adjustment mechanism 20 includes a connecting bolt 202 and a pad 201. The connecting bolt 202 is connected to the bottom of the base 10, and the pad 201 is connected to the connecting bolt 202. The bottom of the pad 201 has a magnetic attraction part 203, which can magnetically attract pads 201 of other heights to change the overall height of the device. Simultaneously, the position / attitude adjustment mechanism 60 includes a ball screw 601 and an angle adjustment rod 602. The ball screw 601 is positioned along the length of the base 10, and the angle adjustment rod 602 is positioned on both sides of the ball screw 601. A set of adjustment bases 30 are positioned on both sides of the base 10. Each adjustment base 30 includes a first body 301, which is configured to cooperate with the ball screw 601 and the angle adjustment rod 602. The oil dispensing block 40 is detachably connected to the adjusting base 30 via a magnetic element 80. The oil dispensing block 40 includes a second body 401 and an oil dispensing nozzle 403. The applicator head 50 is covered outside the oil dispensing nozzle 403. The oil storage mechanism 701 is connected to the oil dispensing nozzle 403 via a conduit that passes sequentially through the first body 301, the magnetic element 80, and the second body 401.
[0105] The core innovation of this embodiment lies in the rapid adsorption and separation of the adjustment base 30 and the oil outlet block 40 through the magnetic element 80, which facilitates the replacement of the matching oil outlet block 40 according to the shape and size of the part to be oiled; at the same time, the height adjustment mechanism 20 and the position and posture adjustment mechanism 60 are configured to drive the adjustment base 30 to move in at least one of the horizontal direction, vertical direction and angle deflection, thereby precisely adjusting the position and posture of the oil outlet block 40 and the application head 50.
[0106] Specifically, when switching to parts of different specifications, the position and angle of the base 30 are adjusted to ensure precise contact between the applicator head 50 and the area to be coated, avoiding uneven coating or missed areas. This design effectively overcomes the compatibility issues caused by differences in part structure in traditional coating methods, significantly improving the adaptability and ease of operation of the device.
[0107] Through the above technical solution, the oiling device can efficiently implement the aforementioned oiling method. During operation, lubricating oil is transported from the oil storage mechanism 701 to the oil outlet 403 through a conduit under the action of gravity, ensuring that the coating head 50 is fully wetted. Once the part to be coated is moved to the coating head 50 and pressure is applied, the lubricating oil is evenly transferred to the surface of the part. Due to the rapid replacement characteristics of the oil outlet block 40 and the multi-directional adjustment capability of the adjustment mechanism, the production line can continuously process parts of different specifications without the need for special fixtures, significantly reducing production costs and floor space. Overall, this embodiment achieves flexibility and high precision in the oiling process through structural innovation, providing a practical solution for multi-variety, small-batch production modes.
[0108] In this embodiment, the first body 301 has a first accommodating cavity 302 for mounting the magnetic element 80 and a second accommodating cavity 303 for collecting excess oil from the applicator head 50. Furthermore, a first adjustment channel 306 for mounting the ball screw 601 and a second adjustment channel 307 for mounting the angle adjustment rod 602 are provided along the length of the first body 301. The end of the ball screw 601 may be equipped with a manual adjustment element 603, such as a knob.
[0109] It should be noted that the shape of the second accommodating cavity 303 can match the shape of the bottom of the applicator head 50.
[0110] It is understood that the second main body 401 has a first connecting channel 402 along its length direction, and the conduit connecting the oil storage mechanism 701 and the oil outlet block 40 passes through the first accommodating cavity 302, the second connecting channel 801 and the first connecting channel 402 in sequence.
[0111] This embodiment further proposes that the oiling device also includes an oil overflow collection mechanism 702; an oil overflow outlet 304 is provided on the first main body 301, and the oil overflow outlet 304 and the oil overflow collection mechanism 702 are connected by a conduit.
[0112] During operation of the oiling device, lubricating oil is transported from the oil storage mechanism 701 through a conduit to the oil outlet 403 of the oil outlet block 40, fully wetting the application head 50. When the part to be oiled comes into contact with the application head 50 and pressure is applied, the lubricating oil is evenly transferred to the surface of the part. During this process, due to factors such as the application head 50 being squeezed or the shape of the part, excess lubricating oil may overflow from the application head 50. In this embodiment, an overflow outlet hole 304 is provided on the first body 301 of the adjusting base 30, providing a direct collection inlet for this overflowing lubricating oil. The overflowing lubricating oil is guided to the overflow outlet hole 304 under gravity or through other auxiliary means. Subsequently, this overflowing oil is safely transported from the overflow outlet hole 304 to the overflow collection mechanism 702 through a conduit. The overflow collection mechanism 702 is responsible for receiving and storing this recovered lubricating oil. This design allows the overflowing lubricating oil to be collected in a timely and effective manner, avoiding disorderly dispersion of lubricating oil and environmental pollution. By integrating the oil spill collection function into the adjustment base 30 and closely matching it with the overall oiling device structure, the continuity and effectiveness of oil spill recovery are ensured during the oiling and adjustment of parts of different specifications, thereby improving the cleanliness and efficiency of the entire oiling operation.
[0113] This embodiment further proposes that the oiling device also includes a solid oil residue collection mechanism 703; a solid oil residue discharge hole 305 is opened at the bottom of the first main body 301, and the solid oil residue discharge hole 305 and the solid oil residue collection mechanism 703 are connected by a conduit.
[0114] This embodiment establishes a solid oil residue discharge and collection system by creating a solid oil residue discharge hole 305 at the bottom of the first main body 301 of the adjusting base 30, and connecting this hole 305 to the solid oil residue collection mechanism 703 via a conduit. During operation of the oiling device, lubricating oil flows inside the adjusting base 30. Solid impurities or oil residue caused by oil aging that may be carried within the oil gradually settle and accumulate at the bottom of the first main body 301 due to gravity. When the solid oil residue accumulates to a certain extent, it can be discharged through the solid oil residue discharge hole 305. The conduit guides this discharged solid oil residue directly to the solid oil residue collection mechanism 703, preventing oil residue from scattering in the working environment and preventing it from re-entering the lubricating oil circulation system. This design ensures the cleanliness of the lubricating oil, maintains the quality of the oiling operation, and simplifies the maintenance and cleaning of the device. In this way, the device can continuously and stably provide clean lubricating oil, effectively solving the potential problems caused by the accumulation of solid oil residue.
[0115] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
