Description

Technical Field

[0001] This utility model relates to the field of lubrication equipment technology for machining, and more specifically, to an ultrasonic atomizing nozzle for micro-lubrication equipment. Background Technology

[0002] In machining processes, lubrication plays a crucial role in improving machining accuracy, extending tool life, and ensuring the quality of machined surfaces. Traditional lubrication methods that rely heavily on cutting fluid are not only costly but also pose significant risks to the environment and the health of operators. Therefore, micro-volume lubrication technology has emerged, which achieves highly efficient lubrication by mixing a very small amount of lubricating oil with compressed gas and then spraying it onto the machining area.

[0003] Traditional micro-lubrication equipment nozzles have many problems in terms of atomization effect and energy consumption. Common nozzle structures are difficult to fully atomize lubricating oil into micron-sized droplets, resulting in poor lubrication effect. At the same time, in order to achieve a certain spray distance and coverage, a large amount of compressed gas is often required, which increases energy costs.

[0004] To avoid the aforementioned problems, ultrasonic atomizing nozzles are currently commonly used for atomization. Ultrasonic atomizing nozzles offer advantages such as good atomization effect and relatively low energy consumption. For example, the invention patent with authorization announcement number CN101773894B discloses a phased-array ultrasonic atomizing nozzle, comprising: a front cover, a rear cover, and a phased-array high-frequency ultrasonic transducer array. The phased-array high-frequency ultrasonic transducer array includes a support member, several array elements, and a phased-array excitation device for driving the array elements. The support member has several holes, with one array element in each hole. All array elements are distributed in a grouped, equally spaced ring array. The support member, inlaid with the array elements, forms a sandwich structure with the front and rear covers. The tip of the amplitude transformer is the liquid atomization surface, and the liquid to be atomized reaches its surface through the central channel. By adopting the above-mentioned phased-array ultrasonic transducer array scheme, the size of the piezoelectric element of a single array element is reduced, providing a higher ultrasonic atomization frequency. Based on the same amplitude transformer structure, the amplitude of the atomization surface can meet the atomization requirements of liquids with higher viscosity, while simultaneously improving the fine atomization of the droplets.

[0005] While this technical solution offers advantages such as improved droplet atomization, most current ultrasonic atomizing nozzles still have some shortcomings in use. Because ultrasonic atomizing nozzles have gas-liquid inlet holes, these holes lack components capable of simultaneously filtering both gas and liquid, failing to filter impurities from lubricating oil and gas, easily leading to impurities entering the nozzle and causing blockage. Some ultrasonic atomizing nozzles also perform filtration at the gas and liquid supply ends; this type of filtration requires at least two filter elements, resulting in high consumable costs and cumbersome subsequent disassembly and cleaning. Therefore, we propose an ultrasonic atomizing nozzle for micro-lubrication devices. Utility Model Content

[0006] The purpose of this invention is to provide an ultrasonic atomizing nozzle for a micro-lubrication device, so as to solve the defects mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An ultrasonic atomizing nozzle for a micro-lubrication device includes an ultrasonic atomizing nozzle body and a gas-liquid inlet support disposed on the ultrasonic atomizing nozzle body. Both ends of the gas-liquid inlet support are provided with threaded holes for connecting to external pipes. A filter assembly is detachably installed inside the gas-liquid inlet support. The filter assembly is inserted along the threaded holes. The filter assembly includes two symmetrical end rings. A filter screen is fixedly installed on the inner wall of the two end rings that are close to each other. Multiple fixed rods arranged in a ring shape at equal intervals are fixedly installed between the sides of the two end rings that are close to each other. A conductive mesh is fixedly installed between two adjacent fixed rods. The conductive mesh has a mesh structure.

[0009] Preferably, the end of the conductive mesh is simultaneously fixedly installed on the end ring, and the number of fixing rods is 4 to 8.

[0010] Preferably, a plurality of inner support ribs arranged in a ring at equal intervals are fixedly installed on the inner wall of the end ring, and the ends of the inner support ribs are fixedly installed on the ends of the fixing rod.

[0011] This design ensures a more secure fixing rod and facilitates the subsequent use of tools such as tweezers to clamp the inner support rib, allowing the filter assembly to be removed from the gas-liquid inlet support.

[0012] Preferably, the height of the inner support rib is between 0.3cm and 0.6cm, and the size of the end ring is adapted to the size of the gas-liquid inlet support.

[0013] Preferably, an annular groove is provided on the outer end face of the end ring, and a sealing ring is embedded in the annular groove.

[0014] Preferably, the interior of the ultrasonic atomizing nozzle body is provided with an inner delivery chamber, an inner conical chamber and a tapering chamber from back to front, and the inner delivery chamber, the inner conical chamber and the tapering chamber are interconnected with each other.

[0015] Preferably, the inner conical chamber is frustum-shaped, and the flared side of the inner conical chamber is connected to the inner delivery chamber;

[0016] Preferably, the inner diameter of the tapering chamber decreases sequentially from back to front, and the outlet diameter of the tapering chamber is between 0.5 mm and 2 mm.

[0017] The above two settings can guide the concentrated injection of the oil-gas mixture, increase the injection speed and distance, and reduce the dispersion of oil mist.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model provides a detachable filter assembly inside the gas-liquid inlet support. The filter screen on the end ring filters impurities in the lubricating oil and gas, while the guide net ensures smooth passage of gas and liquid. This effectively intercepts impurities in the gas and liquid, preventing impurities from entering the nozzle and causing blockage, thereby improving the nozzle's service life and stability.

[0020] 2. This utility model sets up multiple fixed rods and conductive meshes arranged in a ring at equal intervals, and installs inner support ribs on the inner wall of the end rings, which ensures the structural strength of the filter assembly and makes it easy to use tweezers or other tools to hold the inner support ribs and remove the filter assembly. This achieves convenient and quick disassembly and cleaning operations, thereby reducing maintenance difficulty and consumable costs.

[0021] 3. This utility model designs the interior of the ultrasonic atomizing nozzle body as an inner delivery chamber, an inner conical chamber, and a gradually narrowing chamber that are connected in sequence. The inner conical chamber is truncated cone-shaped, and the inner diameter of the gradually narrowing chamber gradually decreases. This achieves effective guidance of the oil-gas mixture, enabling concentrated spraying of the oil-gas mixture, increasing the spraying speed and distance, reducing oil mist dispersion, and improving the micro-lubrication effect.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-5 This utility model provides a technical solution: an ultrasonic atomizing nozzle for a micro-lubrication device, including an ultrasonic atomizing nozzle body 1 and a gas-liquid inlet support 10 disposed on the ultrasonic atomizing nozzle body 1. Both ends of the gas-liquid inlet support 10 are provided with threaded holes 11 for connecting to external pipes, so that the ultrasonic atomizing nozzle body 1 can be easily connected to external pipes to achieve stable gas-liquid inlet.

[0032] In this embodiment, a filter assembly 2 is detachably installed inside the gas-liquid inlet support 10. The filter assembly 2 is inserted along the threaded hole 11. The filter assembly 2 includes two symmetrical end rings 20 on the left and right. A filter screen 201 is fixedly installed on the inner wall of the end rings that are close to each other. The filter screen 201 can effectively filter impurities in the gas and liquid, thereby purifying the gas and liquid entering the nozzle, preventing impurities from clogging the internal structure of the nozzle, and ensuring the stable operation of the equipment.

[0033] Specifically, multiple fixed rods 22 arranged in a ring at equal intervals are fixedly installed between the sides of the two end rings 20 that are close to each other. A conductive mesh 23 is fixedly installed between each pair of adjacent fixed rods 22. The conductive mesh 23 has a mesh structure, and the ends of the conductive mesh 23 are fixedly installed on the end rings 20. The number of fixed rods 22 is 4 to 8. This ensures that the filter assembly 2 has good filtration performance while ensuring that gas and liquid can pass smoothly through the mesh structure of the conductive mesh 23. This achieves a balance between filtration and conduction functions, and achieves the effect of impurity filtration without affecting the gas and liquid transport efficiency.

[0034] like Figure 3As shown, multiple inner support ribs 202 arranged in a ring at equal intervals are fixedly installed on the inner wall of the end ring 20. The ends of the inner support ribs 202 are fixedly installed on the ends of the fixing rod 22, making the connection of the fixing rod 22 more secure. At the same time, the inner support ribs 202 are easy to grip with tools such as tweezers, which makes it convenient and quick to remove the filter assembly 2 from the gas-liquid inlet support 10, thereby facilitating the cleaning and maintenance of the filter assembly 2 and extending its service life.

[0035] Furthermore, the height of the inner support rib 202 is between 0.3cm and 0.6cm, and the size of the end ring 20 is adapted to the size of the gas-liquid inlet support 10, so that the inner support rib 202 can provide sufficient support strength and ensure that the filter assembly 2 is tightly installed with the gas-liquid inlet support 10, thereby achieving the effect of ensuring the stable operation and sealing performance of the filter assembly 2.

[0036] like Figure 4 As shown, an annular groove 203 is provided on the outer end face of the end ring 20, and a sealing ring 21 is embedded in the annular groove 203. After the corresponding gas-liquid pipe is screwed into the threaded hole 11, the end of the corresponding gas-liquid pipe is exactly against the sealing ring 21, which improves the sealing effect and prevents leakage.

[0037] like Figure 5 As shown, the ultrasonic atomizing nozzle body 1 has an inner delivery chamber 12, an inner conical chamber 13, and a tapered chamber 14 arranged sequentially from back to front inside. The inner delivery chamber 12, the inner conical chamber 13, and the tapered chamber 14 are interconnected, so that the gas-liquid mixture undergoes a process of stable delivery, initial convergence, and accelerated injection in sequence inside. This achieves the orderly guidance and acceleration of the gas-liquid mixture, realizes the purpose of concentrated injection of the gas-liquid mixture, improves the injection speed and distance, reduces oil mist dispersion, and enhances the micro-lubrication effect.

[0038] like Figure 5 As shown, the inner conical chamber 13 is truncated cone-shaped. The flared side of the inner conical chamber 13 is connected to the inner conveying chamber 12. The inner diameter of the tapered chamber 14 decreases from back to front. The outlet diameter of the tapered chamber 14 is between 0.5mm and 2mm, which allows the gas-liquid mixture to gradually converge and accelerate during the flow process, thereby further improving the spraying effect and increasing the lubrication efficiency.

[0039] When using the ultrasonic atomizing nozzle of the micro-lubrication device of this utility model, first connect the external gas-liquid pipeline to the gas-liquid inlet support 10 through the threaded hole 11, and then place the end of the pipeline against the sealing ring 21 in the annular groove 203 on the outer end face of the end ring 20 to ensure a seal.

[0040] Next, the gas-liquid mixture enters through the threaded hole 11 and passes through the filter screen 201 and the conductive screen 23 of the filter assembly 2. Impurities are intercepted, and the pure gas and liquid continue to move forward.

[0041] Subsequently, the gas-liquid mixture enters the ultrasonic atomizing nozzle body 1, is first stably transported in the inner delivery chamber 12, then flows into the frustum-shaped inner cone chamber 13 for initial convergence, and finally enters the gradually decreasing inner diameter chamber 14 for acceleration.

[0042] If maintenance is required after a period of use, first disassemble the gas delivery pipe or liquid delivery pipe. Use tweezers to hold the inner support rib 202 on the inner wall of the end ring 20 and remove the filter assembly 2 from the gas-liquid inlet support 10 for cleaning or replacement to ensure the equipment continues to operate efficiently.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
