Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machine tool air source processing device. Background Technology

[0002] In industrial production, some equipment uses compressed air as power to operate; these are called pneumatic systems, such as carbon molecular sieve nitrogen generation systems. Before providing power to a pneumatic system, the passing gas needs to be processed using an air source treatment device to ensure that the power source meets the system's requirements. CNC machine tools require an external air source during operation. Because the air source requirements of different parts of the machine tool vary, an air source treatment device for CNC machine tools has been invented to meet these needs and ensure stable machine tool operation.

[0003] In related technologies, air source processing devices consist of three parts: an air filter, a pressure reducing valve, and an oil mist lubricator. The air filter removes various impurities such as solid particles, moisture, and oil from the air; the pressure reducing valve stabilizes the air pressure; and the oil mist lubricates the moving parts of the machine. However, when the air source is unexpectedly disconnected, the entire device immediately shuts off air supply, making pneumatic components prone to damage. Furthermore, its air path is usually relatively simple, making it unsuitable for various types of machinery and lacking versatility. Therefore, this utility model proposes an air source processing device for CNC machine tools to solve the above problems. Utility Model Content

The output terminal of branch three is sequentially fixedly connected to a branch pressure regulator, an airway switch, and a branch fast response mechanism.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1 to 3 This utility model provides a technical solution: a CNC machine tool air source treatment device, including: a pipeline 1 and a buffer tank 13. The pipeline 1 is the main connecting part of the device. External gas passes through the various parts of the device in sequence through the pipeline 1, thereby entering each branch to supply air to the machine. The pipeline 1 is connected in sequence to an air filter 2, a drain filter 4, an oil removal filter 6, an energy storage device 7, a buffer tank 13 and a dryer 8, and then connected to branch 18, branch 29 and branch 3 20. The output end of branch 18, branch 29 and branch 3 20 are all fixedly connected to an air pipe switch 21. Branch 18, branch 29 and branch 3 20 supply air to different machines through the combination of different components.

[0020] The output end of branch 18 is sequentially and fixedly connected to branch pressure regulator 15 and air pipe switch 21, which can realize branch pressure regulation and control switch functions, making it suitable for applications such as machine tool spindle air seal, taper hole cleaning, and grating ruler air seal. Branch 2 19 realizes branch control switch function through air pipe switch 21, making it suitable for applications such as machine tool spindle tool cutting. The output end of branch 3 20 is sequentially and fixedly connected to branch pressure regulator 15, air pipe switch 21, and branch quick response 16. Branch pressure detector 17 is fixedly connected inside branch quick response 16, which can realize branch pressure regulation, control switch, quick response, and pressure detection functions, and can be used for applications such as loosening and locking of the A-axis and C-axis of the five-axis head of the machine tool.

[0021] Air filter 2 has a filter screen 3 fixedly connected to its inner wall. When gas passes through, it can filter impurities and particulate matter in the air. Drain filter 4 has an adsorbent 5 fixedly connected to its inner wall. Since the adsorbent 5 has water absorption properties, it can filter moisture in the air when gas passes through. Oil filter 6 is filled with oil removal resin. The horizontal height of the pipe 1 at the inlet of oil filter 6 is lower than the horizontal height of the pipe 1 at the outlet, so that gas can pass through the oil removal resin and thus filter oil and gas in the air.

[0022] The fixing plate 14 is cross-shaped and fixedly connected to the inner wall of the pipe 1 connected to the input end of the buffer tank 13, so that it does not affect the air flow rate. A spring 11 is fixedly connected to the midpoint of the fixing plate 14. The spring 11 can control the movement range of the cover plate 12. The other end of the spring 11 is fixedly connected to one end of the cover plate 12. Four guide rods 10 are fixedly connected to the inner wall of one end of the buffer tank 13. The guide rods 10 can guide the cover plate 12 to prevent it from deviating. The other end of the guide rod 10 passes through the cover plate 12 and is fixedly connected to a limiting plate. The limiting plate prevents the cover plate 12 from detaching from the guide rods 10. The cover plate 12 is slidably connected to the guide rods 10. When the gas enters the buffer tank 13 from the pipe 1, the cover plate 12 will exert a pulling force on the spring 11 to extend it. The area of ​​the cover plate 12 is larger than the cross-sectional area of ​​the pipe 1. The edge of the cover plate 12 does not contact the arc-shaped inner wall of the buffer tank 13 to prevent the gas from being unable to enter the buffer tank 13.

[0023] The inner wall of the dryer 8 is fixedly connected to an electric heating wire 9. By energizing the electric heating wire 9, the air can be further dried. Once the air is clean and dry, a stable pneumatic pressure can be obtained through the energy storage device 7.

[0024] In actual use, the entire device is powered on, and then gas is supplied to pipeline 1 through an external gas source. The gas passes through air filter 2, drain filter 4, oil removal filter 6, energy storage device 7, buffer tank 13 and dryer 8 before entering branch 18, branch 29 and branch 30. During this process, due to the high gas pressure, the cover plate 12 moves along the guide rod 10, and both ends of the buffer tank 13 are open. When the gas supply is suddenly interrupted, the gas pressure drops sharply, causing the spring 11 to pull the cover plate 12 back along the guide rod 10, closing one end of the buffer tank 13 while the other end continues to supply gas. Branch 18, branch 29 and branch 30 in the device are classic and commonly used branches. Through multiple functions such as pressure regulation, control switch, fast response and pressure detection, variant configurations can be achieved, thereby adapting to various machines and functions. The device has high overall applicability.

[0025] 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.
