Description

Technical Field

[0001] This utility model relates to the field of micro-lubrication technology, specifically to a universal pipeline for oil delivery in 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 universal 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 universal tubing can achieve normal delivery and supply of lubricating oil, general universal tubing does not have a magnetic sleeve angle adjustment structure. This not only makes it inconvenient to adjust the angle of the tubing, but also makes it easy for the internal connecting pipes to fold, which hinders rapid oil delivery. Furthermore, misalignment can cause the oil supply point to deviate significantly, and it is also difficult to control the trajectory of the oil nozzle. As a result, the normal delivery of lubricating oil by the universal tubing is affected, the normal operation of the lubrication system is disrupted, and the overall practicality is poor. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a universal pipeline for oil delivery in a micro-lubrication system. It can effectively solve the problems in the prior art, which does not have a magnetic sleeve angle adjustment structure. This not only makes it inconvenient to adjust the angle of the pipeline, but also makes it easy for the internal connecting pipe to fold due to the general pipeline adjustment structure, which makes it difficult to deliver oil quickly. Furthermore, the oil supply point is prone to deviate significantly due to misalignment, and it is also difficult to control the trajectory of the oil nozzle. As a result, the universal pipeline can not deliver lubricating oil normally, which affects the normal operation of the normal lubrication system and leads to poor overall practicality.

[0005] The technical solution adopted by this utility model is: a universal pipeline for oil delivery in a micro-lubrication system, including a connecting pipe, a disk assembly and a sealing assembly. A connecting frame is sleeved on the outer edge of the connecting pipe, and the connecting frame is snapped into the connecting pipe. A disk assembly is provided at the end of the connecting pipe away from the connecting frame, and a connecting sleeve and a sealing assembly are fixedly installed at the end of the connecting pipe close to the connecting frame. The disk assembly includes an mounting sleeve and a protective sleeve. A first magnetic sleeve is fitted onto the end of the mounting sleeve away from the protective sleeve, and a second magnetic sleeve is fitted onto the end of the first magnetic sleeve away from the mounting sleeve.

[0006] Preferably, the first magnetic sleeve has a "frustum" cross-section, the first magnetic sleeve and the second magnetic sleeve have the same shape, the first magnetic sleeve and the second magnetic sleeve are movably connected, and a limiting plate is sleeved on the end of the second magnetic sleeve away from the first magnetic sleeve, and the limiting plate is in contact with the connecting tube.

[0007] The above technical solution provides a rotating contact surface for the two magnetic sleeves through the inclined side of the frustum-shaped structure. The movable connection allows the two to rotate along the contact surface, which can drive the connecting pipe to change the oil outlet direction to adapt to different lubrication points. Furthermore, the two magnetic sleeves are attracted by magnetic force, and after rotating to the target angle, they can maintain their position through magnetic attraction without the need for additional locking components, thus improving their practicality.

[0008] Preferably, the connecting tube passes through the first magnetic sleeve and the second magnetic sleeve and extends to its other end, and an oil outlet is fixedly installed at the end of the connecting tube away from the connecting frame.

[0009] Through the above technical solution, the design of the connecting pipe ensures that the internal channel will not be blocked when the magnetic sleeve is passed through. Even if the magnetic sleeve rotates and changes direction, the oil passage inside the pipe will not be excessively blocked due to bending. Furthermore, the through-through design of the connecting pipe ensures that the magnetic sleeve always rotates around the axis of the pipe body, making it easier to control the offset trajectory of the oil nozzle during rotation and preventing the oil supply point from deviating significantly due to magnetic sleeve misalignment.

[0010] Preferably, the sealing assembly includes a sealing sleeve and a sealing ring, the diameters of the sealing sleeve and the sealing ring being the same as the diameter of the connecting pipe, and the sealing ring being made of rubber.

[0011] The above technical solution uses a rubber sealing ring with an inner diameter slightly smaller than the outer diameter of the connecting pipe. After assembly, it undergoes elastic deformation, tightly fitting the outer wall of the connecting pipe and the inner wall of the sealing sleeve, filling the gap and preventing leakage. Furthermore, the rubber material has good elasticity and can adapt to pressure changes under high-pressure oil impact, maintaining the sealing effect.

[0012] Preferably, a second connecting sleeve is fitted around the outer edge of the sealing sleeve, and a limiting end sleeve is fixedly installed at one end of the second connecting sleeve near the first connecting sleeve, and the limiting end sleeve is in contact with the connecting tube.

[0013] The above technical solution, through the reinforcement of the sealing sleeve by the connecting sleeve two and the fitting of the limiting end sleeve to the connecting pipe, forms a double protection of reinforcement and limiting, preventing the sealing component from shifting due to pipeline rotation or vibration, and can extend the service life of the seal.

[0014] Preferably, a slot is provided along the inner edge of the connecting frame, and a clip is fixedly installed on the connecting frame through the slot. An installation block is fixedly installed on the other end of the clip away from the connecting frame. Two identical connecting frames are provided, and a positioning bolt is provided between the two connecting frames.

[0015] Through the above technical solution, by cooperating with the connecting frame and the clip, different sections of the connecting pipe can be fixed by the two connecting frames respectively. The positioning bolt can be adjusted by loosening and tightening, and the clip is embedded in the slot to fix the connecting frame. The mounting block can fix the entire pipeline to the equipment by bolts to prevent the pipeline from shifting as a whole due to equipment vibration.

[0016] Preferably, a limiting groove is provided at the inner edge of the connecting frame, and a limiting sleeve and an anti-slip sleeve are fixedly installed at the inner edge of the connecting frame, wherein the limiting sleeve and the anti-slip sleeve are in contact with the connecting pipe.

[0017] By using the above technical solution, the connecting pipe is fitted with the limiting sleeve and anti-slip sleeve of the connecting frame, and the axial sliding of the connecting pipe in the connecting frame can be prevented by friction, so as to avoid misalignment between the oil outlet and the lubrication point, thereby affecting the normal use of the overall universal pipeline.

[0018] Compared with the prior art, this utility model provides a universal pipeline for oil delivery in a micro-lubrication system, which has the following beneficial effects: 1. The universal pipeline for oil delivery in this micro-lubrication system, through the design of the connecting pipe, can keep the internal channel from being blocked when passing through the magnetic sleeve. Even if the magnetic sleeve rotates and changes direction, the oil passage inside the pipe will not be excessively blocked due to bending. In addition, the through design of the connecting pipe ensures that the magnetic sleeve always revolves around the axis of the pipe body when rotating, making it easy to control the offset trajectory of the oil nozzle during rotation, and preventing the oil supply point from being significantly deviated due to the misalignment of the magnetic sleeve. 2. The universal piping used in this micro-lubrication system for oil delivery uses a connecting frame and clamps to fix different sections of the connecting pipe separately. The positioning bolts can be adjusted by loosening or tightening, and the clamps are embedded in the slots to fix the connecting frames. The mounting block can be bolted to fix the entire pipeline to the equipment to prevent the pipeline from shifting due to equipment vibration. The inner diameter of the rubber sealing ring is slightly smaller than the outer diameter of the connecting pipe. After assembly, it undergoes elastic deformation, tightly fitting the outer wall of the connecting pipe and the inner wall of the sealing sleeve, filling the gap and preventing leakage. Furthermore, the rubber material has good elasticity and can adapt to pressure changes under high-pressure oil impact, preventing leakage. 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 a universal pipeline for oil delivery in a micro-lubrication system, including a connecting pipe 1, a disk assembly 7 and a sealing assembly 10. A connecting frame 2 is sleeved on the outer edge of the connecting pipe 1, and the connecting frame 2 is snapped into the connecting pipe 1. The disk assembly 7 is provided at the end of the connecting pipe 1 away from the connecting frame 2, and a connecting sleeve 9 and a sealing assembly 10 are fixedly installed at the end of the connecting pipe 1 close to the connecting frame 2. The disk assembly 7 includes an installation sleeve 701 and a protective sleeve 702. A first magnetic sleeve 703 is sleeved on the end of the installation sleeve 701 away from the protective sleeve 702, and a second magnetic sleeve 704 is sleeved on the end of the first magnetic sleeve 703 away from the installation sleeve 701.

[0023] Specifically, the first magnetic sleeve 703 has a "frustum" shaped cross section. The first magnetic sleeve 703 and the second magnetic sleeve 704 have the same shape. The first magnetic sleeve 703 and the second magnetic sleeve 704 are movably connected. The end of the second magnetic sleeve 704 away from the first magnetic sleeve 703 is fitted with a limiting disk 705. The limiting disk 705 fits against the connecting pipe 1. The advantage is that the inclined side of the frustum structure provides a rotating contact surface for the two magnetic sleeves. The movable connection allows the two to rotate along the contact surface, which can drive the connecting pipe 1 to change the oil outlet direction to adapt to different lubrication points. In addition, the two magnetic sleeves are attracted by magnetic force. After rotating to the target angle, they can maintain their position by magnetic attraction without the need for additional locking parts, which improves their practicality.

[0024] Specifically, the connecting pipe 1 passes through the first magnetic sleeve 703 and the second magnetic sleeve 704 and extends to its other end. The end of the connecting pipe 1 away from the connecting frame 2 is fixedly equipped with an oil outlet 8. The advantage is that, through the design of the connecting pipe 1, the internal channel can be kept from being blocked when passing through the magnetic sleeve. Even if the magnetic sleeve rotates and changes direction, the oil passage inside the pipe will not be blocked due to excessive bending. Furthermore, the through design of the connecting pipe 1 ensures that the magnetic sleeve always revolves around the axis of the pipe body when rotating, so that the offset trajectory of the oil outlet 8 during the rotation is controllable and the oil supply point will not be greatly deviated due to the misalignment of the magnetic sleeve.

[0025] Specifically, the sealing assembly 10 includes a sealing sleeve 1001 and a sealing ring 1004. The diameters of both the sealing sleeve 1001 and the sealing ring 1004 are the same as the diameter of the connecting pipe 1. The sealing ring 1004 is made of rubber. Its advantage is that, since the inner diameter of the rubber sealing ring 1004 is slightly smaller than the outer diameter of the connecting pipe 1, it undergoes elastic deformation after assembly, tightly fitting the outer wall of the connecting pipe 1 and the inner wall of the sealing sleeve 1001, filling the gap and preventing leakage. Furthermore, the rubber material has good elasticity and can adapt to changes in pressure under high-pressure oil impact, maintaining the sealing effect.

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

[0027] Specifically, a connecting sleeve 1002 is fitted around the outer edge of the sealing sleeve 1001. A limiting end sleeve 1003 is fixedly installed at one end of the connecting sleeve 1002 near the connecting sleeve 19. The limiting end sleeve 1003 fits into the connecting pipe 1. The advantage is that the sealing sleeve 1001 is reinforced by the connecting sleeve 1002, and the limiting end sleeve 1003 fits into the connecting pipe 1, forming a double protection of reinforcement and limitation, preventing the sealing assembly 10 from shifting due to pipeline rotation or vibration, and extending the service life of the seal.

[0028] Specifically, a slot 11 is provided at the inner edge of the connecting frame 2. A clip 12 is fixedly installed on the connecting frame 2 through the slot 11. An installation block 13 is fixedly installed on the other end of the clip 12 away from the connecting frame 2. There are two identical connecting frames 2. A positioning bolt 6 is provided between the two connecting frames 2. The advantage is that, through the cooperation of the connecting frame 2 and the clip 12, different sections of the connecting pipe 1 can be fixed by the two connecting frames 2 respectively. The positioning bolt 6 can be adjusted by loosening or tightening. The clip 12 is embedded in the slot 11 to fix the connecting frame 2. The installation block 13 can be used to fix the entire pipeline to the equipment with bolts to prevent the pipeline from shifting as a whole due to equipment vibration.

[0029] Specifically, a limiting groove 3 is provided at the inner edge of the connecting frame 2, and a limiting sleeve 4 and an anti-slip sleeve 5 are fixedly installed at the inner edge of the connecting frame 2. The limiting sleeve 4 and the anti-slip sleeve 5 are in contact with the connecting pipe 1. The advantage is that by using the limiting sleeve 4 and the anti-slip sleeve 5 of the connecting frame 2 to fit the connecting pipe 1, the connecting pipe 1 can be prevented from sliding axially in the connecting frame 2 by friction, thus avoiding misalignment between the oil outlet 8 and the lubrication point, which would affect the normal use of the overall universal pipeline.

[0030] Working Principle: During use, the inclined side of the frustum-shaped structure provides a rotating contact surface for the two magnetic sleeves. The movable connection allows both to rotate along the contact surface, which can drive the connecting pipe 1 to change the oil outlet direction to adapt to different lubrication points. Furthermore, the two magnetic sleeves are magnetically attracted, and after rotating to the target angle, they can maintain their position through magnetic attraction, eliminating the need for additional locking components and improving practicality. The design of the connecting pipe 1 ensures that the internal channel does not become blocked when passing through the magnetic sleeves. Even if the magnetic sleeves rotate and change direction, the oil passage inside the pipe will not become excessively blocked due to bending. The through-hole design of the connecting pipe 1 ensures that the magnetic sleeves always rotate around the pipe body axis, making the offset trajectory of the oil outlet 8 controllable during rotation and preventing significant deviation of the oil supply point due to magnetic sleeve misalignment. The inner diameter of the rubber sealing ring 1004 is slightly smaller than the outer diameter of the connecting pipe 1. After assembly, it undergoes elastic deformation, tightly fitting the outer wall of the connecting pipe 1 and the inner wall of the sealing sleeve 1001, filling the gap and preventing leakage. Furthermore, the rubber material has good elasticity and can adapt to pressure changes under high-pressure oil impact, maintaining the sealing effect. The sealing sleeve 1001 is reinforced by the connecting sleeve 2 1002, and the limiting end sleeve 1003 fits against the connecting pipe 1, forming a double protection of reinforcement and limitation, preventing the sealing component 10 from shifting due to pipeline rotation or vibration, and extending the service life of the seal. Through the cooperation of the connecting frame 2 and the clamp 12, different sections of the connecting pipe 1 can be fixed by the two connecting frames 2 respectively. The positioning bolt 6 can be adjusted by loosening and loosening, and the clamp 12 is embedded in the clamp groove 11 to fix the connecting frame 2. The mounting block 13 can fix the entire pipeline to the equipment by bolts, avoiding the pipeline from shifting as a whole due to equipment vibration. The limiting sleeve 4 and anti-slip sleeve 5 of the connecting frame 2 fit against the connecting pipe 1, and the friction can prevent the connecting pipe 1 from sliding axially in the connecting frame 2, preventing the oil outlet 8 from being misaligned with the lubrication point, thus affecting the normal use of the entire universal pipeline.

[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.
