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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a noise-reducing multi-axis CNC machine tool, including a noise-reducing plate 1. A top plate 2 supports the top of the noise-reducing plate 1. Multiple heat-absorbing plates 17 made of high-efficiency heat-absorbing material are fixedly connected to the bottom of the solid top plate 2. Two elastic pressure-reducing pads 16 are stably fixedly connected to the bottom sides of the multiple heat-absorbing plates 17, reducing the pressure between the machine and the ground. A solid and stable base plate 15 is fixedly connected to the top of the pressure-reducing pads 16. A limiting plate 14 is fixedly connected to the top of the base plate 15. Two guide rail compartments 13 are fixedly connected to the bottom of the limiting plate 14, effectively preventing displacement of the guide rail compartments 13. Multiple well-made dampers 11 are fixedly connected to each damper 11. A strong spring 12 is fitted on the outside of each damper 11. A stable limiting plate 29 is fixedly connected to the top of each damper 11 to prevent the damper from shaking or displacing. The limiting plate 29 has a precision threaded connection to the support column 9. The top of the sturdy support column 9 is stably and firmly connected to the limiting plate 8. The top of the limiting plate 8 is fixedly connected to the pressure relief plate 7. The top of the pressure relief plate 7 is fixedly connected to the pressure relief plate 6. The pressure relief plate 7 effectively and evenly distributes the pressure transmitted from the pressure relief plate 6. The top of the pressure relief plate 6 is tightly attached to the solid pressure plate 5. A cooling component for heat dissipation is fixedly connected to the opposite side of the heat absorption plate 17.

[0033] Reference Figures 2 to 4The core component of the cooling system is the water-cooled pipe 18, meticulously crafted from high-quality thermally conductive material. Its right side is precisely and firmly fixedly connected to the adjacent side of multiple heat-absorbing plates 17, ensuring a seamless connection and efficient heat transfer from the heat-absorbing plates 17 to the water-cooled pipe 18. Both the upper and lower ends of the water-cooled pipe 18 are securely connected to water-cooling interfaces 19, which are exquisitely designed and have excellent sealing properties, preventing coolant leakage during circulation. Multiple water-cooled plates 20 are neatly and firmly fixedly connected to the sides of the multiple water-cooled pipes 18 that are furthest from each other. The water-cooled plates 20 are made of metal materials with excellent thermal conductivity and heat dissipation capabilities, and their surfaces are specially treated to increase the heat dissipation area. Noise-reducing plates 21 are tightly fixedly connected to the sides of the water-cooled plates 20 that are furthest from each other. Noise-reducing plates 21 utilize advanced sound absorption and insulation technology to effectively reduce noise transmission during equipment operation. The top plate 2 is firmly fixed to the noise reduction plate 3 22 on the opposite sides. The material and structure of the noise reduction plate 3 22 are optimized to effectively block noise of specific frequencies.

[0034] Multiple fans 24 are evenly and securely fixed inside the top plate 2. These fans 24 are high-performance cooling fans with stable speed and low noise, capable of generating a strong and stable airflow inside the equipment to accelerate heat dissipation. A dust cover 23 is securely fixed to the top of the top plate 2. The dust cover 23 is made of fine filter material, effectively preventing dust and other impurities from entering the equipment, protecting the cleanliness and normal operation of internal components. A cooling chamber 25 is securely fixed to the rear side of the noise reduction plate 3 22. The cooling chamber 25 has a reasonable internal space layout and good heat insulation performance. A refrigeration box 26 is tightly fixed to the right side of the cooling chamber 25. The refrigeration box 26 uses advanced refrigeration technology and efficient refrigeration components to quickly reduce the temperature of the coolant. A water-cooled box 27 is securely fixed to the front side of the refrigeration box 26. The water-cooled box 27 provides a stable storage and circulation space for the coolant. Its internal coolant circulation system is scientifically designed to ensure smooth flow of coolant throughout the entire cooling assembly, achieving efficient heat dissipation and cooling function.

[0035] Reference Figures 1 to 3The water-cooled box 27, with its robust and precise structural design, is seamlessly connected to the right side of the noise-reducing plate 1 on its left side. The connection point is specially treated to ensure a strong and airtight connection, effectively preventing coolant leakage. The refrigeration box 26, thanks to its advanced manufacturing process and precise assembly technology, is firmly and reliably connected to the rear right side of the noise-reducing plate 1 on its front left side. This tight connection lays a solid foundation for the stable operation of the entire cooling system. The top of the pressure plate 5 is fixedly connected to the fixing plate 4 using a high-strength welding process. The fixing plate 4 is made of high-quality metal material and has excellent load-bearing capacity and stability. The rear sides of the two fixing plates 4 are precisely positioned and firmly connected to the operating bed 3. As the core operating area of ​​the entire processing equipment, the bottom left and right sides of the operating bed 3 are firmly fixed to the top of the two pressure plates 5, providing a solid support platform for the operation process.

[0036] The top of the water-cooled plate 20 is securely connected to the bottom of the top plate 2 using specialized connecting components. The connection points are evenly distributed and have high strength, ensuring efficient heat transfer. Similarly, the top of the noise-reducing plate 21 is reliably connected to the bottom of the top plate 2, effectively reducing noise interference during equipment operation. A high-performance, low-noise motor 28 is carefully installed on the front of the water-cooled box 27, providing strong power for the coolant circulation in the water-cooling system. The top of the water-cooling interface 19 is precisely connected to the bottom of the top plate 2 through meticulous machining and installation, ensuring smooth flow of coolant during circulation. The spring 12, with its excellent elasticity and durable material, is precisely connected to the bottom of the inner wall of the limiting plate 29 at its top, and firmly connected to the top inner wall of the limiting plate 14 at its bottom, effectively buffering vibration and impact during equipment operation. The guide rail compartment 13 has a precise internal structure and is slidably connected to the telescopic rod 10. The telescopic rod 10 has a smooth surface and is made of hard material. The top ends of the two telescopic rods 10 are firmly fixed to the bottom sides of the limiting plate 8, which provides a strong guarantee for the stable operation and precise operation of the equipment.

[0037] Working principle: When machining with a CNC machine tool, the noise generated by the operating bed 3 is absorbed by the surrounding noise reduction plates 1, 21, and 22. The vibration generated when the operating bed 3 rotates at high speed is borne by the pressure plate 5, which releases the pressure to the pressure relief plate 6. The pressure relief plate 6 evenly distributes the pressure on the pressure relief plate 7. The pressure is then transmitted to the support column 9 through the limiting plate 8. The support column 9 is connected to the limiting plate 29, which evenly distributes the pressure to the damper 11 to release the vibration generated during machine operation. The pressure release by the damper 11 allows the operating bed 3 to run smoothly.

[0038] When the operating bed 3 is in operation, the heat generated starts the motor 28. The heat is dissipated by the fan 24 inside the top plate 2 and flows through the water cooling box 27 to the water cooling pipe 18 fixed inside the water cooling plate 20. The water flowing through the water cooling pipe 18 absorbs heat and releases cold air. After one cycle, it flows to the cooling chamber 25 for cooling. After cooling, it flows to the refrigeration box 26 for refrigeration and finally flows back to the water cooling box 27 to wait for the next cycle. The cooling effect is achieved through the water inside the water cooling pipe 18 and the heat absorption plate 17 fixed on the surface of the water cooling pipe 18.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
