[0014] Flexibility: The program can be edited, and the processing technology can be adjusted conveniently and quickly, which is suitable for the production needs of multiple varieties and small batches.

[0015] Application areas:

[0016] Due to its high efficiency and high precision, CNC lathes are widely used in precision parts processing in aviation, automobile, mold, electronics, medical and other industries.

[0017] With the advancement of intelligent manufacturing and Industry 4.0, the intelligence, networking and automation levels of CNC lathes will be further improved to better serve the development of modern manufacturing.

[0018] The application number is CN202220725115.7, which includes a base, an oil tank is arranged above the base, an oil spray device is arranged above the oil tank, and an adjustment component is arranged between the oil tank and the oil spray device.

However, the use steps of the equipment for oil spraying are relatively complicated and the use is not simple enough.

[0019] Therefore, in view of this, the existing deficiencies are studied and improved, and a CNC lathe oil injection mechanism is proposed. Utility Model Content

The diameter of the auxiliary oil pipe is smaller than that of the main oil pipe, so as to facilitate the distinction between the main spraying area and the remaining areas.

[0028] Furthermore, the number of the main oil pipes and the auxiliary oil pipes is equal to the number of the oil injection ports, so that the area over which the lubricating oil is sprayed can cover the surface of the oil injection tank.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] 1. The utility model pushes the electric actuator body toward one end after being energized, and the electric actuator body drives the active push plate to squeeze the outer side of the plastic oil tank, and the plastic oil tank is deformed after being squeezed, and at the same time, the abutment plate abuts against the outer side of the plastic oil tank, and the telescopic cylinder reduces the impact on the abutment plate, thereby simplifying the steps of exporting the oily liquid;

At the same time, the guide oil pipe composed of the auxiliary oil pipe and the main oil pipe guides the lubricating oil out. This ensures the efficient operation of the lubrication system, improves the operating performance of mechanical equipment and the convenience of maintenance, and plays an important role. It is particularly suitable for industrial applications with high lubrication requirements and complex systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Automatic control: Since the electric actuator body 301 is used to control the entire spraying process, this design realizes the automation of the spraying operation, reduces the need for manual operation, and improves the convenience and efficiency of operation.

[0043] Precise spraying: The active push plate 302 and the abutment plate 304 are used in combination with the telescopic cylinder 303, so that the plastic oil tank 5 can be squeezed evenly and stably, thereby ensuring that the lubricating oil liquid can be sprayed out evenly and continuously. This is very suitable for application scenarios that require precise control of the spraying amount and spraying speed.

[0044] Structural stability: The telescopic cylinder 303 in the design provides the necessary support to ensure that the shape and position of the plastic oil tank 5 remain stable during the extrusion process, which helps to avoid uneven spraying caused by deformation or displacement of the container.

[0045] Strong adaptability: This structure can be applied to plastic oil tanks 5 of different volumes and shapes, and can easily adapt to different operating requirements by adjusting the configuration of the electric actuator body 301, the active push plate 302 and the telescopic cylinder 303.

[0046] Easy maintenance and operation: The simple design and high degree of automation make daily maintenance and operation simpler and more direct. Users can adjust the spraying parameters through simple settings, reducing the possibility of wrong operation caused by complex settings. This design of spraying structure 3 is designed to provide an efficient, stable and easy-to-control liquid spraying solution, suitable for use in various industrial applications that require precise control of lubricant or other liquid distribution.

[0047] like Figure 1-Figure 5 As shown, a CNC lathe oil injection mechanism, the auxiliary structure 9 includes a main oil pipe 901, an auxiliary oil pipe 902 and a pressure oil cover 903, the bottom end of the oil guide cylinder 8 is provided with a pressure oil cover 903, the top end of the oil guide cylinder 8 is provided with a main oil pipe 901, the outer side of the main oil pipe 901 is provided with an auxiliary oil pipe 902, the diameter of the auxiliary oil pipe 902 is smaller than the diameter of the main oil pipe 901, the pressure oil cover 903 is impacted by the lubricating oil and moves upward, the oil guide cylinder 8 guides the lubricating oil into the main oil pipe 901 and the auxiliary oil pipe 902, and then the main oil pipe 901 and the auxiliary oil pipe 902 guide the lubricating oil from the oil injection port 6, which brings the following significant effects:

[0048] Dividing and controlling the flow direction of lubricating oil: The lubricating oil can be effectively diverted and directed to different parts through the design of the main oil pipe 901 and the auxiliary oil pipe 902. The larger diameter of the main oil pipe 901 allows more lubricating oil to pass through, while the smaller diameter auxiliary oil pipe 902 is used for finer or small flow oil delivery. This design increases the flexibility of the system and the accuracy of lubricating oil distribution.

[0049] Improve pressure utilization efficiency: The pressure oil cover 903 is designed to move upward under the impact of the lubricating oil. This movement can help relieve the internal pressure, ensure the stability of the lubricating oil during its rise in the oil guide tube 8, and help push the lubricating oil to flow upward into the main oil pipe 901 and the auxiliary oil pipe 902.

[0050] Enhance the sealing and safety of the system: The mobility of the pressure oil cover 903 not only helps the flow of lubricating oil, but also has a certain sealing effect, reduces the leakage of lubricating oil, and ensures the cleanliness and safety of the oil transportation process.

[0051] Optimizing lubrication effect: The reasonable configuration of the main oil pipe 901 and the auxiliary oil pipe 902 allows the lubricating oil to be more evenly and effectively distributed to various parts of the machine that need lubrication, thereby improving the stability of the machine operation and extending the service life of the machine parts.

[0052] Improve the convenience of maintenance: The main oil pipe 901 and the auxiliary oil pipe 902 in the design are easy to observe and replace, making the daily maintenance and inspection of the system more convenient and quick. The design of this auxiliary structure 9 plays an important role in ensuring the efficient operation of the lubrication system and improving the operating performance and maintenance convenience of mechanical equipment. It is particularly suitable for industrial applications with high lubrication requirements and complex systems.

[0053] Working principle: When using the CNC lathe oil injection mechanism, first install the oil injection box 1 inside the CNC machine tool, while the groove 2 is connected to the external device, and the inside of the plastic oil tank 5 is filled with lubricating oil, while the oil injection port 6 is aligned with the position that needs to be lubricated.
