Description

Technical Field

[0001] This utility model relates to the field of micro-lubrication technology, specifically to an oil delivery pipeline for a micro-lubrication system. Background Technology

[0002] Micro-volume lubrication systems are a highly efficient and environmentally friendly lubrication technology that replaces traditional wet lubrication, which uses a large amount of cutting fluid. The core of this technology is to precisely deliver the lubricating medium to the cutting or machining contact point between the tool and the workpiece through an atomized mixture of a very small amount of lubricating oil and compressed air. It achieves the core functions of lubrication, cooling, and friction reduction with only a small amount of oil film, while significantly reducing the consumption of lubricating medium and the emission of environmental pollutants. For the lubrication system, the oil delivery pipeline is the core component, and its design must take into account flexibility, sealing, corrosion resistance, and fluid uniformity.

[0003] In existing technologies, although lubricating oil can be normally transported and supplied through oil pipelines, the fixed structure of general oil pipelines has not been improved. This not only makes it difficult to improve positioning stability, but also makes the positioning structure less versatile, thus hindering its widespread use. Furthermore, the lack of multi-layer pipeline design makes it difficult to separate the air and oil transport, resulting in poor overall practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an oil pipeline for a micro-lubrication system. It can effectively solve the problems in the prior art, which is that the pipeline fixing structure has not been improved, which not only makes it difficult to improve the positioning stability, but also makes the positioning structure less versatile, thus making it difficult to promote and use. Furthermore, the lack of a multi-layer pipeline design makes it difficult to separate the air and oil transportation, resulting in poor overall practicality.

[0005] The technical solution adopted by this utility model is: an oil supply pipeline for a micro-lubrication system, including a connecting sleeve and a nozzle, an inner tube is fixedly installed at the end of the connecting sleeve away from the nozzle, a first limiting seat and a second limiting seat are fixedly installed at the end of the inner tube away from the nozzle, an installation frame is snapped between the first limiting seat and the second limiting seat, an outer tube is sleeved at the end of the inner tube away from the nozzle, and a positioning component is provided at the end of the inner tube away from the nozzle; The positioning component includes an outer casing, a positioning frame, and a magnetic base. The outer casing and the positioning frame are interlocked. The positioning frame has a magnetic groove at the end away from the outer casing, and the magnetic base has a mounting seat fixedly installed at the end away from the positioning frame.

[0006] Preferably, a positioning sleeve, an extension sleeve, and a positioning frame are fixedly installed at the end of the outer sleeve away from the nozzle. A positioning groove, an extension groove one, and an extension groove two are provided along the inner edge of the positioning frame. The positioning sleeve, the extension sleeve, and the positioning frame correspond to the positioning groove, the extension groove one, and the extension groove two.

[0007] The above technical solution forms a multi-layer nested positioning structure by having the outer positioning sleeve, extension sleeve, positioning frame, positioning groove, extension groove one, and extension groove two correspond one-to-one, which enables the oil pipeline to connect with the lubrication pump or machine tool interface and avoids poor oil delivery or leakage caused by installation misalignment.

[0008] Preferably, the diameters of the positioning sleeve, extension sleeve, and positioning frame decrease from the edge to the center, and the diameters of the positioning sleeve, extension sleeve, and positioning frame are the same as those of the positioning sleeve, extension sleeve, and positioning frame.

[0009] The above technical solution, by using positioning sleeves, extension sleeves, and positioning frame diameters that decrease from the edge to the center, not only achieves progressive nesting to improve positioning stability, but also enhances the versatility of positioning components, adapting to external device interfaces of different specifications, facilitating multi-scenario adaptation and stable connection.

[0010] Preferably, a positioning hole is provided through the outer edge of the mounting base, and multiple positioning holes are provided, which are distributed in a ring about the center line of the mounting base.

[0011] Through the above technical solution, multiple annularly distributed positioning holes provide multi-point fixation for the mounting base, improving the stability of the connection between the positioning component and external equipment, and preventing pipeline displacement during the operation of the micro-lubrication system.

[0012] Preferably, both the inner tube and the outer tube are made of nylon tube material. The inner tube passes through the outer tube and extends to the outer edge. A fixing seat one is fixedly installed at the end of the outer tube near the nozzle, and a fixing seat two is fixedly installed at the end of the outer tube away from the nozzle.

[0013] The above technical solution uses nylon tubing for both the inner and outer tubes. Nylon tubing has excellent oil resistance, flexibility, and anti-aging properties, which prevents lubricating oil from corroding the pipes or causing them to age and crack. The inner tube is used for oil flow, while the outer tube is used for air flow, which improves the overall practicality of the device. In addition, the outer tube is prevented from shifting when it is fixed with fixing seat one and fixing seat two.

[0014] Preferably, a protective sleeve one and a protective sleeve two are fixedly installed at the outer edge of the inner tube away from the nozzle, and the two ends of the protective sleeve one and the protective sleeve two are respectively.

[0015] The above technical solution involves wrapping the inner tubes at both ends of the positioning component with protective sleeve one and protective sleeve two, which facilitates protection of the ends and prevents wear or sealing failure at the connection between the positioning component and the pipeline due to vibration or friction, while also enhancing the rigidity of the connection.

[0016] Preferably, a slot is provided along the inner edge of the mounting frame, the slot having the same diameter as the inner tube, two identical mounting frames are provided, and a mounting bolt is threaded between the two mounting frames, the connecting sleeve and the nozzle are threadedly connected, and a retaining sleeve is fixedly installed at the connection between the connecting sleeve and the nozzle.

[0017] Through the above technical solution, the two mounting frames clamp the inner tube with mounting bolts, and the ferrule seals the connection between the sleeve and the nozzle, forming a pipeline that is easy to fix. The nozzle position can be adjusted according to the actual working conditions to prevent oil delivery deviation caused by displacement of the inner tube.

[0018] Compared with the prior art, this utility model provides an oil delivery pipeline for a micro-lubrication system, which has the following beneficial effects: 1. The oil pipeline of this micro-lubrication system forms a multi-layer nested positioning structure through the one-to-one correspondence between the outer positioning sleeve, extension sleeve, positioning frame and positioning groove, extension groove one and extension groove two. This not only achieves progressive nesting to improve positioning stability, but also improves the versatility of positioning components, adapts to different specifications of external device interfaces, and facilitates multi-scenario adaptation and stable connection. 2. The oil pipeline of this micro-lubrication system is made of nylon tubing, with both the inner and outer layers made of nylon. Nylon tubing has excellent oil resistance, flexibility and anti-aging properties, which prevents lubricating oil from corroding the pipeline or causing the pipeline to age and crack. The inner layer is used for oil flow and the outer layer is used for air flow, which improves the practicality of the overall device. In addition, with the fixing of fixing seat one and fixing seat two, the displacement of the outer layer is prevented. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: As Figure 1-7 As shown, the present invention provides an oil supply pipeline for a micro-lubrication system, including a connecting sleeve 1 and a nozzle 2. An inner tube 3 is fixedly installed at the end of the connecting sleeve 1 away from the nozzle 2. A limiting seat 5 and a limiting seat 9 are fixedly installed at the end of the inner tube 3 away from the nozzle 2. An installation frame 6 is snapped between the limiting seat 5 and the limiting seat 9. An outer tube 11 is sleeved at the end of the inner tube 3 away from the nozzle 2. A positioning component 14 is provided at the end of the inner tube 3 away from the nozzle 2. The positioning component 14 includes an outer sleeve 1401, a positioning frame 1404, and a magnetic base 1409. The outer sleeve 1401 and the positioning frame 1404 are engaged. A magnetic groove 1408 is provided at the end of the positioning frame 1404 away from the outer sleeve 1401. A mounting base 1410 is fixedly installed at the end of the magnetic base 1409 away from the positioning frame 1404.

[0023] Specifically, a positioning sleeve 1402, an extension sleeve 1403, and a positioning frame 1404 are fixedly installed at the end of the outer sleeve 1401 away from the nozzle 2. A positioning groove 1405, an extension groove one 1406, and an extension groove two 1407 are provided on the inner edge of the positioning frame 1404. The positioning sleeve 1402, the extension sleeve 1403, and the positioning frame 1404 correspond to the positioning groove 1405, the extension groove one 1406, and the extension groove two 1407. The advantage is that by having the positioning sleeve 1402, the extension sleeve 1403, and the positioning frame 1404 of the outer sleeve 1401 correspond one-to-one with the positioning groove 1405, the extension groove one 1406, and the extension groove two 1407, a multi-layer nested positioning structure is formed, which allows the oil pipeline to connect with the lubrication pump or machine tool interface, avoiding oil supply obstruction or leakage caused by installation misalignment.

[0024] Specifically, the diameters of the positioning sleeve 1402, extension sleeve 1403, and positioning frame 1404 decrease from the edge to the center. The diameters of the positioning sleeve 1402, extension sleeve 1403, and positioning frame 1404 are the same as those of the positioning sleeve 1402, extension sleeve 1403, and positioning frame 1404. The advantage is that by decreasing the diameters of the positioning sleeve 1402, extension sleeve 1403, and positioning frame 1404 from the edge to the center, a progressive nesting is achieved to improve positioning stability, and the versatility of the positioning component 14 is improved, adapting to different specifications of external device interfaces, facilitating multi-scenario adaptation and stable connection.

[0025] Specifically, a positioning hole 1411 is provided through the outer edge of the mounting base 1410. Multiple positioning holes 1411 are provided, and the multiple positioning holes 1411 are distributed in a ring about the center line of the mounting base 1410. The advantage is that the multiple ring-distributed positioning holes 1411 provide multiple points of fixation for the mounting base 1410, improve the stability of the connection between the positioning component 14 and the external equipment, and prevent the pipeline from shifting during the operation of the micro-lubrication system.

[0026] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0027] Specifically, both the inner tube 3 and the outer tube 11 are made of nylon. The inner tube 3 passes through the outer tube 11 and extends to the outer edge. A fixing seat 10 is fixedly installed at the end of the outer tube 11 near the nozzle 2, and a fixing seat 2 12 is fixedly installed at the end of the outer tube 11 away from the nozzle 2. The advantage is that since both the inner tube 3 and the outer tube 11 are made of nylon, which has excellent oil resistance, flexibility and anti-aging properties, it avoids the corrosion of the pipeline by lubricating oil or the aging and cracking of the pipeline. At the same time, the inner tube 3 is used for oil flow and the outer tube 11 is used for air flow, which can improve the practicality of the overall device. In addition, with the fixing of the fixing seat 10 and the fixing seat 2 12, the displacement of the outer tube 11 is prevented.

[0028] Specifically, protective sleeve 13 and protective sleeve 2 15 are fixedly installed on the outer edge of the inner tube 3 away from the nozzle 2. Protective sleeve 13 and protective sleeve 2 15 are respectively positioned at both ends of the positioning component 14. The advantage is that by wrapping the inner tube 3 at both ends of the positioning component 14 with protective sleeve 13 and protective sleeve 2 15, it is easy to protect the ends and avoid wear or sealing failure at the connection between the positioning component 14 and the pipeline due to vibration or friction, while also enhancing the rigidity of the connection.

[0029] Specifically, a slot 8 is provided on the inner edge of the mounting frame 6. The slot 8 has the same diameter as the inner tube 3. There are two identical mounting frames 6. The two mounting frames 6 are connected by a threaded mounting bolt 7. The connecting sleeve 1 and the nozzle 2 are threaded together. A retaining sleeve 4 is fixedly installed at the connection between the connecting sleeve 1 and the nozzle 2. The advantage is that the two mounting frames 6 clamp the inner tube 3 by the mounting bolt 7, and the retaining sleeve 4 seals the connecting sleeve 1 and the nozzle 2, forming a pipeline that is easy to fix. The position of the nozzle 2 can be adjusted according to the actual working conditions to prevent oil delivery deviation caused by the displacement of the inner tube 3.

[0030] Working Principle: During use, the positioning sleeve 1402, extension sleeve 1403, and positioning frame 1404 of the outer sleeve 1401 correspond one-to-one with the positioning groove 1405, extension groove one 1406, and extension groove two 1407, forming a multi-layer nested positioning structure. This allows the oil pipeline to connect with the lubrication pump or machine tool interface, preventing oil supply obstruction or leakage due to installation misalignment. The diameter of the positioning sleeve 1402, extension sleeve 1403, and positioning frame 1404 decreases from the edge to the center, achieving progressive nesting to improve positioning stability and enhance the versatility of the positioning component 14. It adapts to different specifications of external equipment interfaces, facilitating multi-scenario adaptation and stable connection. Multiple annularly distributed positioning holes 1411 provide multi-point fixation for the mounting base 1410, improving the stability of the connection between the positioning component 14 and external equipment, and preventing pipeline displacement during the operation of the micro-lubrication system. All the inner tubes 11 are made of nylon tubing. Nylon tubing has excellent oil resistance, flexibility and anti-aging properties, which prevents lubricating oil from corroding the pipeline or causing the pipeline to age and crack. The inner tube 3 is used for oil flow, and the outer tube 11 is used for air flow, which can improve the practicality of the overall device. In addition, with the fixing of fixing seat 10 and fixing seat 2 12, the outer tube 11 is prevented from shifting. The inner tubes 3 at both ends of the positioning component 14 are wrapped by protective sleeve 13 and protective sleeve 2 15, which facilitates the protection of the ends and prevents wear or sealing failure at the connection between the positioning component 14 and the pipeline due to vibration or friction. At the same time, it enhances the rigidity of the connection. The two mounting frames 6 clamp the inner tubes 3 with mounting bolts 7. The clamping sleeve 4 seals the connecting sleeve 1 and the nozzle 2 to form a pipeline for easy fixing. The position of the nozzle 2 can be adjusted according to the actual working conditions to prevent oil delivery deviation caused by the displacement of the inner tube 3.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
