Description

Technical Field

[0001] This utility model relates to the field of lubricating oil application technology, and more specifically to a lubricating oil application device. Background Technology

[0002] The air guide plate of a typical split-type internal unit is driven by a motor and a TB linkage device. The TB linkage component is assembled from a connecting rod and upper and lower swing rods. During the assembly process, silicone grease needs to be evenly applied to the mushroom head surfaces at both ends of the connecting rod to achieve effective lubrication.

[0003] The connecting rod assembly is automated, and the workflow is as follows: connecting rod positioning, oiling the mushroom head of the upper swing arm, assembling the upper swing arm, oiling the mushroom head of the lower swing arm, assembling the lower swing arm, and completing assembly and packaging. Currently, the initial oiling of the mushroom heads of the upper and lower swing arms is done using methods such as... Figure 1 The straight-through oiling mechanism shown injects silicone grease from the top of the mushroom head and forces it onto the surface using pressure. However, in actual use, due to the viscosity of silicone grease, the straight-through mechanism cannot evenly coat the mushroom head surface; only the top of the mushroom head has silicone grease. This results in the connecting rod contact surface lacking silicone grease after assembly, leading to lubrication failure and jamming after prolonged rotation. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a lubricating oil application device that can evenly apply lubricating oil to the surface of an object and has the advantages of simple structure and easy operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lubricating oil application device is provided, comprising:

[0007] A housing, wherein the housing has a cavity for storing oil;

[0008] This casing is primarily used for storing oil.

[0009] The applicator includes a groove and an oiling hole formed on the inner sidewall of the groove. The groove is used to fit an object to be coated with oil, and the oiling hole is connected to the cavity.

[0010] Because the applicator nozzle has a groove, the object to be coated can be inserted into the groove. The oiling holes on the inner wall of the groove connect to a cavity, allowing oil from the cavity to be guided and applied to the sidewalls of the groove, thus coating the side of the object. In practical applications, the oil in the cavity can be forced out through the oiling holes under pressure.

[0011] In some embodiments, the housing is a cylindrical housing, and the cavity is configured as a flow channel that extends along the length of the cylindrical housing.

[0012] Manufacturing the casing as a cylindrical casing allows for smooth oil output and improves oil output efficiency.

[0013] In some embodiments, one end of the cylindrical housing is recessed inward to form the groove.

[0014] A groove is formed at the bottom of the cylindrical shell, making the whole structure more compact and facilitating the connection between the oiling holes on the groove and the flow channels of the cylindrical shell.

[0015] In some embodiments, the opening diameter of the groove is at least 0.5 to 1 cm smaller than the cross-sectional diameter of the cylindrical shell.

[0016] The opening diameter of the groove is kept at least 0.5 to 1 cm smaller than the cross-sectional diameter of the cylindrical shell, so that there is space between the groove and the shell for the oil to flow, allowing the oil in the cylindrical shell to flow smoothly to the side wall of the groove.

[0017] In some embodiments, a piston rod is fitted within the flow channel, and the piston rod is movable back and forth along the groove, either towards or away from it.

[0018] A piston rod is used to push the oil within the flow channel, allowing the oil to be extruded quickly. The piston rod is embedded within the flow channel, further propelling the oil under high pressure.

[0019] In some embodiments, the cross-sectional area of ​​the flow channel is larger than the bottom surface area of ​​the groove, and the piston rod is engaged and slides within the flow channel.

[0020] Since the cross-sectional area of ​​the flow channel is larger than the bottom area of ​​the groove, and the piston rod slides within the flow channel, the end of the piston rod can stop on the bottom surface of the groove. The piston rod will not be inserted directly into the side wall of the groove, thus avoiding affecting the flow of oil from the oiling holes on the side wall of the groove.

[0021] In some embodiments, the piston rod has a plurality of guide grooves at one end facing the groove, the guide grooves extending to the bottom surface of the piston rod end.

[0022] Furthermore, each guide groove points in a straight line to the oiling hole on the inner wall of the groove.

[0023] Since the guide groove points to the bottom of the groove and connects to the oiling hole, it can guide the oil to flow out of the oiling hole first, thus improving the oil output efficiency.

[0024] In some embodiments, a plurality of oiling holes are provided, which are evenly distributed on the inner sidewall of the groove.

[0025] Multiple oiling holes can evenly coat the sidewalls of the object with oil. Preferably, four oiling holes are provided, which are evenly distributed on the inner sidewalls of the groove.

[0026] In some embodiments, the object is the mushroom head of a connecting rod. In practical applications, it can also be other objects. Furthermore, the oil is preferably silicone grease.

[0027] The beneficial effects of this utility model of a lubricating oil application device are as follows:

[0028] This utility model discloses a lubricating oil application device. An oil nozzle is provided on the housing containing the oil. This nozzle has a groove with oiling holes on the inner wall of the groove. When the nozzle applies lubricating oil or other oil to an object, the object is inserted into the groove, and the oiling holes on the side wall of the groove spray oil onto the object. This allows the oil to be applied specifically to the side of the object, preventing highly viscous oil from being unevenly applied and effectively improving the accuracy of the application. Furthermore, the structure is simple, easy to operate, and suitable for large-scale production applications. Attached Figure Description

[0038] Example 1

[0039] For the lubricating oil application device disclosed in this embodiment, please refer to [link / reference needed]. Figures 2-4 ,include:

[0040] A housing 1, wherein a cavity 2 is provided inside the housing 1 for storing oil;

[0041] The casing 1 is mainly used for storing oil.

[0042] The applicator 3 includes a groove 4 and an oiling hole 5 formed on the inner side wall of the groove 4. The groove 4 is used to fit an object to be oiled, and the oiling hole 5 is connected to the cavity 2.

[0043] Because the applicator nozzle 3 has a groove 4, the object to be applicated can be inserted into the groove 4. The oiling hole 5, located on the inner wall of the groove 4, connects to the cavity 2, thus guiding the oil from the cavity 2 and applying it to the side wall of the groove 4, thereby applicating the side of the object. In practical applications, the oil in the cavity 2 can be squeezed out into the oiling hole 5 by applying pressure.

[0044] The applicator nozzle 3 includes a groove 4 and an oiling hole 5 formed on the inner wall of the groove 4. The groove 4 is used to accommodate the object to be coated with oil, while the oiling hole 5 connects to the cavity 2 of the housing 1.

[0045] Because the applicator nozzle 3 has a groove 4, the object to be applicated can be inserted into the groove 4. The oiling hole 5, located on the inner wall of the groove 4, connects to the cavity 2, thus guiding the oil within the cavity 2 and applying it to the side of the object.

[0046] In practical applications, the oil inside cavity 2 can be forced into the coating hole 5 by applying pressure. This means that the flow rate of the oil can be adjusted by controlling the pressure, achieving precise coating.

[0047] An oil return device can be installed in the groove 4. The oil return device includes a vacuum generator, a pressure regulator, and an air flow regulating device to quickly remove residual oil pressure in the oiling channel after oiling, preventing oil from continuing to overflow when the oiling nozzle is retracted after oiling, which would affect the oiling quality of the product.

[0048] It also allows for the setting of switches to control the automatic oil dispenser and the oil nozzle-driven cylinder. These switches enable precise control of the oil supply pressure and delivery time, thereby achieving high-precision control of the oil application amount.

[0049] Therefore, this efficient, uniform, and precise oil application system is suitable for various applications requiring precise lubrication.

[0050] Example 2

[0051] Please see Figures 2-4 To ensure that the oil can be efficiently transferred to the oiling hole 5, based on Example 1, the housing 1 is disclosed as a cylindrical housing 1, the cavity 2 is constructed as a flow channel, and the flow channel extends along the length direction of the cylindrical housing 1.

[0052] Manufacturing the shell 1 as a cylindrical shell 1 can smoothly output the oil and improve the oil output efficiency.

[0053] The shell 1 is designed as a cylindrical structure, which facilitates the smooth flow of oil along the length of the shell 1. The cavity 2 of the cylindrical shell 1 is constructed as a flow channel, which extends along the length of the cylindrical shell 1. This design ensures that the oil flows within the shell 1 with reduced resistance, thereby improving the oil output efficiency.

[0054] The flow channel needs to take into account the dynamic characteristics of oil flow to ensure that the oil can flow efficiently from one end to the other. The shape and size of the flow channel need to be optimized according to the physical properties of the oil (such as viscosity, density, etc.) and the required flow rate.

[0055] The flow channel design of the cylindrical shell 1 can be optimized through computer simulation and experimental testing to ensure the uniformity and continuity of oil flow, further reduce flow resistance, and improve oil output efficiency.

[0056] Example 3

[0057] Please see Figures 2-4 To make the entire oiling device more compact and easier to stably fit objects, based on Embodiment 2, one end of the cylindrical shell 1 is recessed inward to form the groove 4.

[0058] A groove 4 is formed at the bottom of the cylindrical shell 1, making the whole structure more compact and facilitating the connection between the oiling hole 5 on the groove 4 and the flow channel of the cylindrical shell 1.

[0059] A recessed area is provided at one end of the cylindrical shell 1 to form a groove 4. This groove 4 is used to fit the object to be lubricated, and its size and shape need to be taken into account to ensure that the object can be smoothly inserted and fixed in the groove 4.

[0060] By forming a groove 4 at the bottom of the cylindrical shell 1, the entire structure becomes more compact. This design reduces the need for additional components, simplifies the overall structure, and also lowers manufacturing costs.

[0061] Oiling holes 5 are made on the inner wall of the groove 4. These oiling holes 5 need to be connected to the flow channels inside the cylindrical shell 1. The oiling holes 5 should ensure that the oil can flow smoothly from the flow channels to the oiling holes 5 and be evenly applied to the side of the object.

[0062] The oiling hole 5 can be connected by directly opening a hole in the flow channel wall of the cylindrical shell 1, or by setting up a pipe, channel or other structure to connect the flow channel to the oiling hole 5. These connection structures need to be well sealed to prevent oil leakage.

[0063] To control the output pressure and flow rate of the oil, a pressure regulating valve or flow control valve can be installed in the flow channel, which can precisely control the output of the oil through the oiling hole 5.

[0064] Example 4

[0065] Please refer to 2-4. In order to improve the effect of oil transfer to the oiling hole 5, based on Example 3, it is disclosed that the opening diameter of the groove 4 is at least 0.5-1 cm smaller than the cross-sectional diameter of the cylindrical shell 1.

[0066] The opening diameter of the groove 4 is kept at least 0.5~1cm smaller than the cross-sectional diameter of the cylindrical shell 1, so that there is space between the groove 4 and the shell 1 for the oil to flow, so that the oil in the cylindrical shell 1 can flow smoothly to the side wall of the groove 4.

[0067] Determine the cross-sectional diameter of the cylindrical shell 1, and then design the opening diameter of the groove 4 to be at least 0.5~1cm smaller than the cross-sectional diameter of the shell 1. This design ensures that there is sufficient space between the shell 1 and the groove 4 for oil flow.

[0068] By maintaining the difference between the opening diameter of the groove 4 and the cross-sectional diameter of the shell 1, an annular space can be formed, which allows the oil to flow from the flow channel of the shell 1 to the side wall of the groove 4, thereby achieving smooth flow of the oil.

[0069] The location and size of the oiling holes 5 are designed to ensure that the oil flows evenly from the flow channel to the sidewalls of the groove 4. The design of the oiling holes 5 should take into account the flow characteristics and pressure of the oil to achieve the best coating effect.

[0070] Example 5

[0071] Please see Figures 2-4 To ensure that the oil can be efficiently transferred to the oiling hole 5, based on Example 4, a piston rod 6 is embedded in the flow channel, and the piston rod 6 can move back and forth along the groove 4.

[0072] The piston rod 6 is used to push the oil in the flow channel, so that the oil can be extruded quickly. The piston rod 6 is embedded in the flow channel, which can further push the oil out under high pressure.

[0073] In the lubricating oil applicator, the piston rod 6 is fitted within the flow channel, causing it to move back and forth along the channel, thereby pushing the oil within the channel. The movement of the piston rod 6 can be achieved manually or through automated mechanical devices to control the flow and extrusion of the oil.

[0074] The piston rod 6 can move back and forth in a direction away from or towards the groove 4. This movement can be achieved by an electric or pneumatic system, wherein the electric system may include a motor and a corresponding transmission device, while the pneumatic system may include a cylinder and a control valve.

[0075] As the piston rod 6 moves along the flow channel, it pushes the oil in the flow channel toward the oiling hole 5, thereby achieving rapid extrusion of the oil. This mechanism is similar to the piston movement in a hydraulic system, which can effectively control the pressure and flow rate of the oil.

[0076] The movement of piston rod 6 can be used in conjunction with a pressure control valve to precisely control the pressure of the oil. This control is crucial for ensuring that the oil is evenly applied to the object, improving both the efficiency and quality of the application.

[0077] Example 6

[0078] Please see Figures 2-4 To ensure that the oil can be efficiently transferred to the oiling hole 5, based on Example 5, the cross-sectional area of ​​the flow channel is disclosed to be larger than the bottom surface area of ​​the groove 4, and the piston rod 6 is embedded in the flow channel and slides.

[0079] Since the cross-sectional area of ​​the flow channel is larger than the bottom area of ​​the groove 4, and the piston rod 6 slides within the flow channel, the end of the piston rod 6 can stop on the bottom surface of the groove 4. The piston rod 6 will not be inserted directly into the side wall of the groove 4, thus avoiding affecting the flow of oil from the oiling hole 5 on the side wall of the groove 4.

[0080] The cross-sectional area of ​​the flow channel is larger than the bottom area of ​​the groove 4. This ensures that when the piston rod 6 moves, there is enough oil in the flow channel to push the piston rod 6, while avoiding the piston rod 6 from directly contacting the side wall of the groove 4 due to insufficient oil.

[0081] The piston rod 6 is embedded in the flow channel and can slide. When the piston rod 6 moves to the bottom surface of the groove 4, since the cross-sectional area of ​​the flow channel is larger than the bottom surface area of ​​the groove 4, the end of the piston rod 6 can be safely stopped on the bottom surface of the groove 4 without exceeding the boundary of the groove 4, thereby preventing the piston rod 6 from being inserted directly into the side wall of the groove 4.

[0082] The large cross-sectional area of ​​the flow channel allows the oil to flow evenly under the push of the piston rod 6, while ensuring that the oil can flow smoothly out of the oiling hole 5 on the side wall of the groove 4 without being obstructed by the movement of the piston rod 6.

[0083] Example 7

[0084] Please see Figures 2-4 To ensure efficient oil transfer to the oiling hole 5, based on embodiment 6, a plurality of guide grooves 7 are provided at one end of the piston rod 6 facing the groove 4, and the guide grooves 7 extend to the bottom surface of the end of the piston rod 6.

[0085] Furthermore, each guide groove 7 points in a straight line to the oiling hole 5 on the inner wall of the groove 4.

[0086] Since the guide groove 7 points to the bottom of the groove 4 and connects to the oiling hole 5, it can guide the oil to flow out of the oiling hole 5 first, thereby improving the oil output efficiency.

[0087] Several guide grooves 7 are formed at one end of the piston rod 6 facing the groove 4. These guide grooves 7 are designed to extend to the bottom surface of the end of the piston rod 6, and each guide groove 7 points in a straight line to the oiling hole 5 on the inner wall of the groove 4.

[0088] The guide groove 7 is designed with precise orientation to ensure that the oil can flow directly from the guide groove 7 to the oiling hole 5. This directional design can reduce the resistance to oil flow and improve the efficiency of oil flowing out of the oiling hole 5.

[0089] Since the guide groove 7 points directly to the oiling hole 5, the oil can flow out from these holes first, which can reduce the residence time of the oil in the groove 4 and improve the oil output efficiency.

[0090] Example 8

[0091] Please see Figures 2-4 The working principle of the oiling hole 5 is explained. Based on embodiment 1, it is disclosed that a plurality of oiling holes 5 are provided, and the plurality of oiling holes 5 are evenly distributed on the inner sidewall of the groove 4.

[0092] Multiple oiling holes 5 can evenly apply oil to the sidewalls of the object. Preferably, four oiling holes 5 are provided, and the four oiling holes 5 are evenly distributed on the inner sidewalls of the groove 4.

[0093] For example, a four-sided oil injection method is used, with the injection angle indicating the direction of the oil injection, to apply silicone grease to the assembly surface of the mushroom head 8. This is mainly because applying silicone grease to the assembly surface before assembly ensures that the surfaces of the connecting rod 9 and the upper and lower swing arms that move relative to each other have sufficient silicone grease for lubrication, while non-assembly surfaces are not coated with silicone grease. Ultimately, this ensures that the assembly surface of the mushroom head 8 is fully and effectively coated with silicone grease, thereby improving product production efficiency and product quality, and reducing the labor intensity of employees. The coating device in this embodiment prevents lubrication failure caused by incomplete or uneven application of silicone grease to the TB connecting rod 9 component during rotation.

[0094] Specifically, by providing oiling holes 5 on the sidewall of the groove 4, which serves as an oiling tray, the moving contact surface (side of the mushroom head 8) around the rotating shaft can be evenly coated. This ensures that the surfaces of the connecting rod 9 and the upper and lower rocker arms moving relative to each other have sufficient silicone grease for lubrication, while preventing silicone grease from being applied to non-assembly surfaces. Ultimately, this ensures that the assembly surface of the mushroom head 8-shaped rotating shaft is fully and effectively coated with silicone grease, improving product production efficiency and quality, and reducing the labor intensity of employees. It effectively ensures that lubricating oil and silicone grease are evenly applied to the moving parts, thus facilitating operation.

[0095] In practical applications, the external shape of the housing 1 and the size of the groove 4 can be adjusted to meet the oiling needs of different connecting rod 9 mechanisms and different mushroom head 8 mounting mechanisms; the number of oiling holes 5 in the groove 4 can be adjusted. When the size of the mushroom head 8 is large and the existing oiling holes do not meet the requirements of uniform coating, the number of oiling holes can be increased to meet the actual use needs.
