Description

Technical Field

[0001] This utility model relates to the field of CNC-assisted machining technology, and in particular to an automatic oiling machine for CNC machining. Background Technology

[0002] In CNC machining, especially during tapping, ensuring proper lubrication of the machining area is crucial. Lubricating oil reduces friction and wear during tapping, improves machining accuracy and surface quality, and extends tool life. However, currently, lubricating oil supply in tapping is still primarily manual, typically involving manually squeezing and spraying oil from a bottle onto the machining area. This method is not only cumbersome and inefficient but also requires continuous oil injection throughout the machining process. This wastes time and labor costs and can lead to uneven or excessive lubrication due to improper operation, thus affecting machining quality. Utility Model Content

[0003] Therefore, it is necessary to provide a more efficient, convenient and precise lubrication system to address the problem of poor efficiency in manual lubrication. This system would enable continuous and stable lubrication during tapping, reduce manual intervention, improve production efficiency, and ensure machining quality. This would be achieved through an automatic lubrication machine for CNC machining.

[0004] An automatic oiling machine for CNC machining includes:

[0005] The main body can be installed on a machine tool. The main body has an airflow channel and an oil storage chamber inside. One end of the airflow channel is connected to the air outlet of the machine tool, and the other end is connected to the top of the oil storage chamber.

[0006] A piston is slidably disposed within the oil reservoir along the length of the main body, and the cross-sectional area of ​​the piston is equal to the cross-sectional area of ​​the oil reservoir; and

[0007] An oil outlet is provided on the main body and is connected to the bottom end of the oil storage chamber; after the airflow channel inputs gas to the top of the oil storage chamber, it will push the piston to move to the bottom of the oil storage chamber and cause the lubricating oil in the oil storage chamber to be sprayed out through the oil outlet.

[0008] The aforementioned automatic lubricating machine for CNC machining automatically inputs gas into the airflow channel through the machine tool. Driven by the gas, the piston slides from the top to the bottom of the oil reservoir, squeezing the stored lubricating oil downwards. Finally, the lubricating oil is sprayed through the nozzle to the machining position on the product. Furthermore, the main body is mounted on the machine tool's tool holder. The operator can control the movement of the nozzle to align with the desired oil spraying position via a program, achieving automated alignment and oil spraying. This automatic lubricating machine is more efficient, convenient, and precise, facilitating continuous and stable lubrication during tapping processes, reducing manual intervention, improving production efficiency, and ensuring machining quality.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Please see Figures 1 to 3 In one embodiment, an automatic oiling machine 100 for CNC machining includes: a main body 1, a piston 2, and an oil outlet 3. The main body 1 can be mounted on a machine tool holder. The main body 1 has an airflow channel 11 and an oil storage chamber 12 inside. One end of the airflow channel 11 communicates with the air outlet of the machine tool, and the other end communicates with the top end of the oil storage chamber 12. The piston 2 is slidably disposed in the oil storage chamber 12 along the length direction of the main body 1, and the piston 2 is interference-fitted with the cavity wall of the oil storage chamber 12. The oil outlet 3 is disposed on the main body 1, and the oil outlet 3 communicates with the bottom end of the oil storage chamber 12.

[0028] The automatic lubricating machine 100 automatically inputs gas into the airflow channel 11 via the machine tool. Driven by the gas, the piston 2 slides from the top to the bottom of the oil storage chamber 12, squeezing the lubricating oil stored in the chamber downwards. Finally, the lubricating oil is sprayed out through the oil nozzle 3 to the processing position of the product. Furthermore, the main body 1 is mounted on the tool holder of the machine tool. The machine tool can control the movement of the oil nozzle 3 to align with the required oil spraying position via a program, enabling automated alignment and oil spraying operations. This automatic lubricating machine 100 is more efficient, convenient, and precise, facilitating continuous and stable lubrication during tapping processes, reducing manual intervention, improving production efficiency, and ensuring processing quality.

[0029] The main body 1 includes a cylindrical first mounting body 13 and a second mounting body 14 disposed on one end of the first mounting body 13. The second mounting body 14 is provided with a locking hole 141. The first mounting body 13 is inserted into the tool holder of the machine tool, and then the main body 1 is locked to the machine tool by bolts passing through the locking hole 141.

[0030] In one embodiment, a step is formed in the middle of the first mounting body 13, and the diameter of the end of the first mounting body 13 that connects to the second mounting body 14 is larger than the diameter of the other end. This structural arrangement of the first mounting body 13 facilitates quick insertion and fixation into the tool holder of the machine tool.

[0031] In one embodiment of the second mounting body 14, the second mounting body 14 is square, and locking holes 141 are provided at each of the four corners of the second mounting body 14. Of course, the second mounting body 14 can also be circular, with multiple locking holes 141, which are evenly spaced along the circumference of the second mounting body 14.

[0032] Please see Figure 2In another embodiment, the first mounting body 13 and the second mounting body 14 are connected vertically to form an oil storage cavity 12, and the bottom end of the second mounting body 14 is connected to the oil outlet 3.

[0033] Furthermore, the second mounting body 14 has an air inlet 15 on its outer side and a first channel 111 inside. The first mounting body 13 has a second channel 112 inside. The first channel 111 communicates with the air inlet 15, and the two ends of the second channel 112 communicate with the top of the first channel 111 and the top of the oil storage chamber 12, respectively. The extending directions of the first channel 111 and the second channel 112 can be perpendicular.

[0034] To ensure that no oil leakage occurs when the piston 2 pushes to inject oil, the automatic oil injector 100 of this utility model also includes a sealing ring. The piston 2 has a groove on its outer periphery, and the sealing ring is fitted into the groove. The sealing ring extends beyond the outer periphery of the piston 2, forming an interference fit between the sealing ring and the cavity wall of the oil storage chamber 12.

[0035] Please see Figure 2 and Figure 3 Furthermore, to ensure that the oil outlet 3 does not leak, the automatic oiler 100 also includes a sealing cover 4 and a leak-proof valve 5. The sealing cover 4 is located at the bottom of the second mounting body 14 and seals the bottom of the oil storage chamber 12. The inlet of the oil outlet 3 passes through the sealing cover 4 and extends into the oil storage chamber 12, and the leak-proof valve 5 is located at the inlet of the oil outlet 3.

[0036] When piston 2 pushes lubricating oil to the bottom of oil reservoir 12, the air pressure inside oil reservoir 12 is greater than the external air pressure, causing the anti-leak valve 5 to open, and the lubricating oil can be sprayed out by the oil outlet 3; when the gas input stops and piston 2 does not exert thrust, the air pressure inside oil reservoir 12 is equal to the external air pressure, and the anti-leak valve 5 will automatically close, so that the lubricating oil in oil reservoir 12 cannot flow out from the oil outlet 3.

[0037] In another embodiment, the automatic oil injector 100 further includes a pressure regulating valve 6, located at the air inlet 15, and used to regulate the gas pressure entering the oil storage chamber 12. When the pressure regulating valve 6 is activated at a high flow rate, the gas flow rate entering the oil storage chamber 12 is larger, and the amount of oil sprayed from the oil outlet 3 will also be larger; when the pressure regulating valve 6 is activated at a low flow rate, the gas flow rate entering the oil storage chamber 12 is smaller, and the amount of oil sprayed from the oil outlet 3 will also be smaller. This allows for precise adjustment of the oil injection volume according to demand.

[0038] Leak-proof valve 5 and pressure regulating valve 6 can be conventional pneumatic valves.

[0039] In addition, the outer side of the main body is provided with an oil inlet that communicates with the oil storage chamber 12 and can be opened or closed. The oil inlet can be located at the bottom of the second mounting body 14. When the lubricating oil in the oil storage chamber 12 is used up, lubricating oil can be replenished into the oil storage chamber 12 through the oil inlet, and the piston 2 will return to the initial position.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications, substitutions, and improvements without departing from the concept of this utility model, and these should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the claims.
