Description

Technical Field

[0001] This invention relates to the field of oiling equipment technology, and specifically to a centrifugal oiling device and its oiling method. Background Technology

[0002] In today's product assembly industry, oiling is a crucial process. Its purpose is to apply an appropriate amount of oil to the workpiece surface to achieve functions such as lubrication, rust prevention, and friction reduction, thereby ensuring product performance and lifespan. Currently, the widely used oiling method in the industry utilizes a solenoid valve in conjunction with an oil spray gun. However, this traditional oiling method has many problems that urgently need to be addressed.

[0003] From the perspective of oil volume control, oil residue always remains at the nozzle of the spray gun. This phenomenon makes it difficult to maintain a consistent oil volume each time spraying, resulting in significant fluctuations. Due to the lack of a precise oil volume control mechanism, it is easy to overspray. Excessive oil not only increases production costs but also contaminates the product and the workbench. Excess oil on the product surface may affect subsequent assembly processes and even lead to a decline in product quality; while oil stains on the workbench are difficult to clean, affecting the cleanliness of the working environment and potentially causing corrosion and other damage to surrounding equipment.

[0004] Regarding the uniformity of oil spraying, the oil sprayed from the spray gun tends to accumulate and cannot achieve uniform distribution. This results in uneven oil application on the workpiece surface, with some areas having too much oil and others too little. This uneven oil spraying effect cannot meet the requirements for precise control of the amount of oil applied, nor can it guarantee the uniformity of the coating on the product surface, thus affecting the overall performance and quality stability of the product.

During oiling, the oil-slinging shaft descends to allow the metering oil groove to enter the workpiece to be oiled, and then the oil-slinging shaft rotates at high speed to evenly throw the oil in the metering oil groove onto the oiling area.

[0009] In some embodiments, an oil receiving container is retractably installed below the oil slinger, the oil receiving container being used to collect oil overflowing from the metered oil tank.

[0010] In some embodiments, the metering oil groove is a cone shape with a larger upper port diameter and a smaller lower port diameter; an oil-collecting tray is provided at one end of the oil-slinging shaft near the limiting member, the upper end of the oil-collecting tray has a conical wall, and the metering oil groove is formed inside the conical wall.

[0011] In some embodiments, a refueling valve is installed on one side of the fuel injector, and the fuel storage container, the refueling valve, and the fuel injector are connected in sequence via an oil pipe.

[0013] In some embodiments, a first pulley is mounted on the upper end of the outer rod, a drive motor is mounted on the first support, and the first pulley is driven to a second pulley on the drive motor via a belt; a first cylinder for driving the lifting platform to move up and down and a second cylinder for driving the oil receiving container to extend and retract are mounted on the first support, and first guide rails for guiding the lifting platform are symmetrically mounted on the first support; a support platform is provided on the first support, a first bearing for supporting the outer rod is installed in the support platform, and a second bearing for supporting the inner rod is installed in the lifting platform.

[0014] In some embodiments, the fuel injector is retractably mounted on a second support of the machine base; a sliding seat is slidably mounted on the second support via a second guide rail, and the fuel injector is inclinedly arranged on the sliding seat; a third cylinder for driving the sliding seat to extend and retract is mounted on the second support.

[0015] In some embodiments, the limiting member adopts a clamping structure, including at least two grippers that can move toward the center, a limiting plate is installed on the inner side of the grippers, and the limiting plate is provided with an arc-shaped groove adapted to the outer wall of the workpiece to be oiled.

[0016] In some embodiments, the oil storage container is an oil storage tank, and the upper end of the oil storage tank is equipped with an oil filling funnel and an oil tank pressure gauge.

[0017] Based on the same inventive concept, the present invention also provides an oiling method for an oiling device, implemented using the aforementioned centrifugal oiling device, comprising the following steps:

[0018] Step S01, Install the workpiece to be coated with oil; Use manual or robotic arm methods to place the workpiece to be coated with oil onto the limiting component, which limits and clamps the workpiece to be coated with oil.

[0019] Step S02, quantitative oil addition; first, the oil receiving container extends to the underside of the oil slinger, then the oil spray gun extends toward the oil slinger, and the oil in the oil storage container is added to the quantitative oil groove of the oil slinger through the oil spray gun. The oil overflowing from the quantitative oil groove falls into the oil receiving container; after the oiling is completed, the oil receiving container and the oil spray gun retract.

[0020] Step S03, oil-slinging operation; the oil-slinging shaft descends to allow the metering oil tank to enter the workpiece to be oiled, and then the oil-slinging shaft rotates at high speed to evenly sling the oil in the metering oil tank onto the oiling area.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the beneficial effects that at least one technical solution adopted in the embodiments of this specification can achieve include at least:

[0023] 1) By setting a metering oil tank on the oil-slinging shaft, precise control of the amount of oil added each time is achieved. The metering oil tank ensures that the amount of oil added each time is the same. At the same time, the oil gun adds oil into the metering oil tank, and the excess oil overflowing is collected by the oil receiving container, which further ensures that the actual amount of oil used for oiling is accurate and avoids problems such as increased costs and product and workbench contamination caused by excessive oil. By using the oil-slinging method, the oil in the metering oil tank can be completely discharged during high-speed rotation, without any oil residue. This makes the actual amount of oil applied to the workpiece in each oiling process precisely controllable, meeting the requirements for precise control of oil application, helping to improve product quality stability, and reducing the adverse effects of inaccurate oil amount on subsequent assembly processes and product performance.

[0024] 2) The oil is applied by a splashing method. When the splashing shaft rotates at high speed, the oil in the metering oil tank is evenly splashed onto the oiling area, avoiding the problem of oil accumulation that occurs when using a traditional spray gun. This ensures that the oil is evenly distributed on the workpiece surface, guaranteeing the uniformity of the coating and thus improving the overall performance and quality stability of the product. Because the oil is evenly splashed onto the oiling area of ​​the workpiece, there is no oil accumulation, reducing oil dripping and accumulation on the worktable. This helps maintain a clean working environment, reduces the difficulty of cleaning oil stains, and avoids potential corrosion damage to surrounding equipment.

[0025] 3) The oil slinger shaft can be raised and lowered freely relative to the limiting parts, which greatly enhances the flexibility and adaptability of the device. It can easily adapt to products of different heights and oiling positions of different locations. By adjusting the height of the oil slinger shaft, the quantitative oil tank can be accurately placed into the oiling position to achieve precise oiling, meet diverse production needs, and improve the versatility and efficiency of the equipment.

[0026] 4) The overall structure of the device is scientifically and rationally designed. The limiting component adopts a clamping structure, which can firmly limit and clamp workpieces of different shapes to be coated by means of the grippers and the arc-shaped grooves on the limiting plate, ensuring the stability of the workpieces during the coating process. The oil spray gun is connected to the oil storage container and the filling valve through the oil pipe, and can be driven to extend and retract on the second support by the third cylinder, which facilitates the precise addition of oil to the metering oil tank. The oil slinger shaft achieves stable rotation and lifting through the cooperation of the outer rod, inner rod, drive rod, transmission components, drive motor, pulley and other components. The division of labor of each component is clear and they work together, making the coating process efficient and reliable. Attached Figure Description

In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0045] Additionally, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that practice can be carried out without these specific details.

[0046] Combination Figures 1-12 As shown, this invention provides a centrifugal oiling device, including a machine base 1 and a limiting member 2, an oil storage container 3, and an oil spray gun 4 mounted on the machine base 1. The limiting member 2 is used to mount the workpiece to be oiled and to limit and clamp it. The oil storage container 3 is used to store oil and is connected to the oil spray gun 4. An oil-slinging shaft 5 is rotatably mounted above the limiting member 2, and the oil-slinging shaft 5 can be raised and lowered relative to the limiting member 2. A metering oil tank 501 is provided on the oil-slinging shaft 5, and the oil spray gun 4 is located on one side of the metering oil tank 501. The oil spray gun 4 is used to add oil into the metering oil tank 501. During oiling, the oil-slinging shaft 5 descends to allow the metering oil tank 501 to enter the interior of the workpiece to be oiled. Then, the oil-slinging shaft 5 rotates at high speed to evenly throw the oil in the metering oil tank 501 onto the oiling area. An oil receiving container 6 is retractably mounted below the oil-slinging shaft 5. The oil receiving container 6 can be an oil receiving box or an oil receiving tray, and is used to collect the oil overflowing from the metering oil tank 501.

[0047] This structure, by incorporating a metering oil groove on the oil slinger shaft, achieves precise control over the amount of oil added each time. Compared to traditional spray guns where residual oil in the nozzle causes fluctuations in spray volume, the metering oil groove ensures a consistent amount of oil added each time, fundamentally solving the oil volume control problem. Simultaneously, the spray gun adds oil to the metering oil groove, and any excess oil is collected by the oil receiving container, further ensuring the accuracy of the actual amount of oil used for coating, avoiding increased costs and product / workbench contamination caused by excessive oil.

[0048] By utilizing a spray-on method, the oil in the metered oil tank is completely discharged during high-speed rotation, leaving no oil residue. This ensures precise control over the amount of oil actually applied to the workpiece during each oiling process, meeting the requirements for precise oil application control. This helps improve product quality stability and reduces the adverse effects of inaccurate oil application on subsequent assembly processes and product performance. The spray-on method evenly distributes the oil in the metered oil tank to the oiling area as the spray shaft rotates at high speed. This avoids the problem of oil accumulation that occurs with traditional spray guns, ensuring uniform oil distribution on the workpiece surface. It overcomes the drawbacks of traditional methods, where some areas have too much oil and others too little, guaranteeing uniform surface coating and thus improving overall product performance and quality stability. Because the oil is evenly sprayed to the oiling area, there is no oil accumulation, reducing dripping and buildup on the worktable, helping to maintain a clean working environment, reducing the difficulty of oil cleaning, and preventing potential corrosion damage to surrounding equipment.

[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the metering oil tank 501 is a cone shape with a larger upper diameter and a smaller lower diameter. This cone shape facilitates the addition of oil from the spray gun 4 into the metering oil tank 501, and also helps to completely eject the oil from the metering oil tank 501 when the oil slinger 5 rotates at high speed. An oil-collecting tray 502 is provided at one end of the oil slinger 5 near the limiting member 2. The upper end of the oil-collecting tray 502 has a conical wall 503, and the metering oil tank 501 is formed inside the conical wall 503.

[0050] In some embodiments, such as Figure 1 As shown, a filler valve 7 is installed on one side of the fuel injector 4. The fuel storage container 3, the filler valve 7, and the fuel injector 4 are connected in sequence via fuel lines (the dotted lines in the diagram represent fuel lines). This structure uses the filler valve 7 to control the opening and closing of the fuel injector 4, facilitating the control of the amount of fuel added.

[0051] In some embodiments, such as Figures 4 to 9As shown, the limiting component 2, the oil slinger shaft 5, and the oil receiving container 6 are all mounted on the first support 101 of the machine base 1. An outer rod 81 is rotatably mounted on the first support 101, and an inner rod 82 is slidably fitted inside the outer rod 81. The oil slinger shaft 5 is connected to the inner rod 82 and is detachably mounted on the lower end of the inner rod 82. If a threaded connection is used, it is convenient to replace the oil slinger shaft 5 according to different products, thus allowing for different metering oil tanks 501 to adapt to the workpiece. A drive rod 83 is connected to the lower end of the outer rod 81, and a transmission component 84 is fitted on the inner rod 82. The outer rod 81, inner rod 82, drive rod 83, transmission component 84, and oil slinger shaft 5 are all arranged coaxially. The inner wall of the drive rod 83 is provided with multiple guide grooves 831 at equal intervals in a ring. The transmission component 84 is placed inside the drive rod 83 and is provided with multiple drive teeth 841 that are adapted to the guide grooves 831. When the drive rod 83 rotates, the drive rod 83 can rotate in conjunction with the transmission component 84 and the inner rod 82 under the cooperation of the guide grooves 831 and the drive teeth 841. When the inner rod 82 and the transmission component 84 move up and down, the drive teeth 841 can slide up and down along the guide grooves 831 without affecting the lifting and lowering function of the oil slinger 5. This structure, through the cooperation of the guide grooves 831 and the drive teeth 841, ensures the lifting and rotation functions of the oil slinger 5, and the operation is stable and reliable. A lifting platform 91 is ellipsably installed on the first support 101. The lifting platform 91 is connected to the inner rod 82 and is used to drive the inner rod 82 and the oil slinger 5 to move up and down.

[0052] In some embodiments, such as Figures 4 to 9 As shown, a first pulley 85 is installed at the upper end of the outer rod 81, and a drive motor 86 is installed on the first support 101. The first pulley 85 is driven by a belt and connected to a second pulley 87 on the drive motor 86. A first cylinder 92 for driving the lifting platform 91 to move up and down and a second cylinder 61 for driving the oil receiving container 6 to extend and retract are installed on the first support 101. A first guide rail 93 for guiding the lifting platform 91 is symmetrically installed on the first support 101. A support platform 102 is provided on the first support 101. The outer rod 81 passes through the support platform 102. The drive rod 83 is located on the lower side of the support platform 102. A first bearing 88 for supporting the outer rod 81 is installed in the support platform 102 to facilitate the rotation of the outer rod 81 relative to the support platform 102. The inner rod 82 passes through the lifting platform 91. The oil slinger 5 is located on the lower side of the lifting platform 91. A second bearing 94 for supporting the inner rod 82 is installed in the lifting platform 91 to facilitate the rotation of the inner rod 82.

[0053] During oiling, the first cylinder 92 drives the lifting platform 91 to descend along the first guide rail 93. The lifting platform 91 drives the inner rod 82, the transmission component 84, and the oil-throwing shaft 5 to descend synchronously. At this time, the drive gear 841 slides downward along the guide groove 831, so that the metering oil tank 501 enters the interior of the workpiece to be oiled. Then the drive motor 86 works, driving the outer rod 81 to rotate through the cooperation of two pulleys. The outer rod 81 drives the drive rod 83 to rotate. With the cooperation of the drive gear 841 and the guide groove 831, the drive rod 83 drives the transmission component 84 and the inner rod 82 to rotate. The inner rod 82 drives the oil-throwing shaft 5 to rotate at high speed, evenly throwing the oil in the metering oil tank 501 onto the oiling area.

[0054] This structure allows the oil slinger shaft to move freely up and down relative to the limiting component, greatly enhancing the flexibility and adaptability of the device. It can easily accommodate products of different heights and oiling locations. Whether for small precision parts or large workpieces, adjusting the height of the oil slinger shaft ensures the precise oil level of the metering oil tank enters the oiling position, achieving accurate oiling, meeting diverse production needs, and improving the equipment's versatility and efficiency.

[0055] In some embodiments, such as Figure 1 and Figure 10 As shown, the oil spray gun 4 is retractably mounted on the second support 103 of the machine base 1. The retractable oil spray gun 4 moves towards the oil slinger shaft during refueling and retracts after refueling to prevent interference with the oil slinger shaft's operation. A sliding seat 42 is slidably mounted on the second support 103 via a second guide rail 41, and the oil spray gun 4 is inclinedly arranged on the sliding seat 42. A third cylinder 43 is mounted on the second support 103 to drive the sliding seat 42 to extend and retract. During refueling, the third cylinder 43 drives the sliding seat 42 to move towards the oil slinger shaft, which in turn drives the oil spray gun 4 to move towards the oil slinger shaft. Then, the refueling valve 7 opens, and the oil spray gun 4 adds oil into the metering oil tank 501.

[0056] In some embodiments, such as Figure 1 and Figure 11 As shown, the workpiece to be coated with oil is generally a cylindrical structure such as a pump body or bottle. In this embodiment, the limiting member 2 adopts a clamping structure. The limiting member 2 includes at least two grippers 21 that can move towards the center. A limiting plate 22 is installed on the inner side of the grippers 21. The limiting plate 22 is provided with an arc-shaped groove 221 that fits the outer wall of the workpiece to be coated with oil. During clamping, the two grippers 21 move towards the center and the workpiece to be coated with oil is limited by the arc-shaped groove 221.

[0057] In some embodiments, such as Figure 1 and Figure 12 As shown, the oil storage container 3 is an oil tank, and an oil filling funnel 31 and an oil tank pressure gauge 32 are installed at the upper end of the oil tank. In this embodiment, the oil storage container 3 is prior art, and will not be described in detail here.

[0058] This device features a scientifically and rationally designed overall structure. The limiting component employs a clamping structure, which, through the grippers and the arc-shaped grooves on the limiting plate, can firmly limit and clamp workpieces of different shapes to be coated, ensuring the stability of the workpieces during the coating process. The oil spray gun is connected to the oil storage container and the filling valve via an oil pipe, and can be extended and retracted on the second support by a third cylinder, facilitating precise addition of oil to the metering oil tank. The oil slinger shaft, through the cooperation of the outer rod, inner rod, drive rod, transmission components, drive motor, pulleys, and other components, achieves stable rotation and lifting. The clear division of labor and coordinated work of each component make the coating process efficient and reliable.

[0059] Based on the same inventive concept, the present invention also provides an oiling method for an oiling device, implemented using the aforementioned centrifugal oiling device, comprising the following steps:

[0060] Step S01: Install the workpiece to be coated with oil; place the workpiece to be coated with oil onto the limiting member 2 by means of manual labor or a robotic arm. The limiting member 2 limits and clamps the workpiece to be coated with oil.

[0061] Step S02, quantitative oil addition; first, the oil receiving container 6 extends to the lower side of the oil slinger 5, then the oil spray gun 4 extends towards the oil slinger 5, and the oil in the oil storage container 3 is added to the quantitative oil tank 501 of the oil slinger 5 through the oil spray gun 4. The oil overflowing from the quantitative oil tank 501 falls into the oil receiving container 6; after the oil addition is completed, the oil receiving container 6 and the oil spray gun 4 retract.

[0062] Step S03, oil-slinging operation; the oil-slinging shaft 5 descends to allow the metering oil tank 501 to enter the workpiece to be oiled, and then the oil-slinging shaft 5 rotates at high speed to evenly sling the oil in the metering oil tank 501 onto the oiling area.
