[0001] The invention relates to the technical field of lubrication of numerically controlled machine tools, in particular to an oil separator block for numerically controlled machine tools. Background Art

[0002] During the operation of CNC machine tools, lubrication between the various moving parts is crucial. Good lubrication can reduce friction, minimize wear, improve the machining accuracy and stability of the machine tool, and extend the service life of the machine tool. However, existing CNC machine tool lubrication systems have many problems. Traditional lubrication methods often adopt a unified oil supply mode, which makes it difficult to accurately supply oil according to the actual needs of different components. This may result in some components being oversupplied with oil, resulting in waste of lubricating oil and oil splashing, polluting the working environment; while some components may not be undersupplied with oil, resulting in poor lubrication effect, accelerated component wear, and affecting the normal operation and machining quality of the machine tool. At the same time, existing lubrication systems lack an effective monitoring mechanism, making it impossible to timely understand the oil supply status of each lubrication point, making it difficult to effectively maintain and adjust the lubrication system. Therefore, it is of great practical significance to develop an oil distributor for CNC machine tools that can achieve precise oil supply and real-time monitoring of the oil supply status.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 - Figure 6The present invention provides a technical solution: an oil separator for a CNC machine tool, comprising an oil separator 1 and an adjusting block 2, an oil inlet 3 being provided on the side of the oil separator 1, a plurality of oil outlets being provided on the top surface of the oil separator 1, a through hole 7 being provided inside the adjusting block 2, a cavity 16 being provided inside the adjusting block 2, the through hole 7 passing through the cavity 16, an adjusting member being installed inside the cavity 16, the adjusting member being used to adjust the flow of lubricating oil, a flow sensor being installed inside the through hole 7 above the cavity 16, the oil outlet being aligned with the bottom end of the through hole 7, a fixing member being provided between the oil separator 1 and the adjusting block 2, the fixing member being The oil separation block 1 and the regulating block 2 are fixed together. During operation, the lubricating oil flows into the oil separation block 1 from the oil inlet 3, and then flows out through the through hole 7 aligned with the bottom end of the oil outlet to supply oil to each lubrication point. The regulating member is installed in the cavity 16, and the flow of lubricating oil can be adjusted according to actual needs; the flow sensor monitors the flow of lubricating oil flowing through the through hole 7 in real time to ensure that the oil supply is stable and meets the requirements, and adjusts the regulating member to change the oil output. The fixing member firmly connects the oil separation block 1 and the regulating block 2 to ensure the stability of the entire oil separation block structure during operation and avoid the influence of vibration and other factors on the oil separation effect.

[0024] As an embodiment of the present invention, the regulating member further includes a pair of meshing gears 15, which are rotatably mounted within a cavity 16 via a connecting shaft. The regulating member also includes a motor 10 mounted on the side of the regulating block 2. The output end of the motor 10 is in transmission connection with one of the gears 15. When the motor 10 is started, the output end drives the gear 15 to rotate. The meshing of the gears 15 causes the other gear 15 to rotate accordingly. When the two gears 15 mesh, they squeeze the lubricating oil within the tooth grooves, pushing it toward the through-hole 7, thereby delivering the lubricating oil. The rotation of the gears 15 changes the flow resistance and speed of the lubricating oil within the cavity 16, thereby precisely regulating the flow of lubricating oil through the through-hole 7. For example, when the motor 10 speeds up, the gear 15 speeds up, increasing the flow of lubricating oil. Conversely, when the motor 10 speeds down, the gear 15 speeds down, reducing the flow of lubricating oil. This allows for the different oil supply requirements of different lubrication points to be met.

[0025] As an embodiment of the present invention, further, the two sides of the cross section of the cavity 16 are semicircular, the middle part of the cross section of the cavity 16 is rectangular, a pair of gears 15 are located in the semicircular cavity, and the sides of the gears 15 are in contact with the semicircular cavity, the diameter of the through hole 7 is equal to the length of the rectangular cavity, and the meshing part of the pair of gears 15 is located in the rectangular cavity. The specially designed cavity 16 structure provides a stable rotation space for the gears 15. The two sides of the semicircle are in contact with the sides of the gears 15, which can effectively guide the lubricating oil to flow evenly when the gears rotate and avoid turbulence. The rectangular part is used to accommodate the gear meshing part, so that the lubricating oil can pass smoothly during the rotation and meshing process of the gears, and provides a stable channel for flow regulation. The diameter of the through hole 7 is equal to the length of the rectangular cavity, which ensures that the lubricating oil can flow smoothly from the cavity 16 into the through hole 7, ensuring the accuracy and stability of the flow regulation.

[0026] As an embodiment of the present invention, a protective cover 5 is further installed on the outside of the adjustment block 2. The bottom surface of the protective cover 5 is provided with a heat dissipation groove. The motor 10 is located inside the protective cover 5. The protective cover 5 is mainly used to protect the internal motor 10 and prevent external dust, debris, etc. from entering to avoid affecting the normal operation of the motor. The heat dissipation groove provided on the bottom surface plays a heat dissipation role. The motor generates heat during operation. The heat is dissipated into the surrounding environment through the heat dissipation groove, maintaining the appropriate operating temperature of the motor, ensuring stable motor performance, avoiding motor failure due to overheating, and thus ensuring that the entire adjustment component can continue to work normally.

[0027] As an embodiment of the present invention, further, the number of oil outlets and through holes 7 is equal, and the number of oil outlets and through holes 7 is equal, which can achieve one-to-one precise oil supply. Each through hole 7 corresponds to an oil outlet, ensuring that the lubricating oil after adjustment and monitoring is accurately delivered to the corresponding lubrication point, avoiding oil supply chaos, improving the accuracy and reliability of oil separation, and ensuring that each lubrication point can obtain an appropriate amount of lubricating oil.

[0028] As an embodiment of the present invention, further, the top surface of the oil separator block 1 is provided with four groups of threaded holes 9, the bottom surface of the regulating block 2 is provided with four groups of openings 11, the top surface of the regulating block 2 is provided with four groups of countersunk holes 12, the countersunk holes 12 and the openings 11 are connected, the fixing member is a bolt 6, the bolt 6 passes through the countersunk holes 12 and the openings 11 and is threadedly engaged with the threaded holes 9, the screw head of the bolt 6 is located in the countersunk hole 12, during installation, the bolt 6 passes through the countersunk holes 12 on the top surface of the regulating block 2 and the openings 11 on the bottom surface in turn, and is threadedly engaged with the threaded holes 9 on the top surface of the oil separator block 1. This connection method allows the oil separator block 1 and the regulating block 2 to be tightly fixed together, ensuring that there will be no relative displacement between the two during the operation of the CNC machine tool, and maintaining the stability of the overall structure of the oil separator block. The design of the countersunk hole 12 allows the screw head of the bolt 6 to sink into it, preventing the screw head from protruding and affecting the normal operation of other components, while also enhancing the aesthetics and safety of the connection.

[0029] As an embodiment of the present invention, a positioning ring 13 is further installed at the top of the oil outlet. The positioning ring 13 slides in the through hole 7. A sealing ring 14 is installed on the outside of the positioning ring 13. The positioning ring 13 slides in the through hole 7 to accurately position the oil outlet and the through hole 7, ensuring that the lubricating oil can flow smoothly from the through hole 7 into the oil outlet, avoiding misalignment that causes oil leakage or uneven oil supply. The sealing ring 14 on the outside of the positioning ring 13 further enhances the sealing effect, prevents lubricating oil from leaking at the connection, ensures that the lubricating oil can be fully delivered to the corresponding lubrication points, and improves the sealing performance and oil supply efficiency of the oil distributor.

[0030] As an embodiment of the present invention, further, a first threaded pipe joint 4 is installed on the end face of the oil inlet 3, and a second threaded pipe joint 8 is installed on the top of the through hole 7. The first threaded pipe joint 4 is convenient for connecting the oil inlet 3 of the oil separator block to the external oil supply pipeline, and the threaded connection ensures a tight connection to prevent lubricating oil leakage. The second threaded pipe joint 8 is used to connect the subsequent lubricating oil delivery pipeline, so that the lubricating oil after adjustment and monitoring by the oil separator block can be smoothly delivered to various lubrication points. The use of threaded pipe joints is not only convenient for installation and disassembly, but also allows for replacement of pipes of different specifications according to actual needs, thereby improving the adaptability of the oil separator block to the entire lubrication system.
