Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a CNC negative pressure drainage base. Background Technology

[0002] In modern manufacturing, especially in precision machining fields such as CNC machining, product sealing and effective management of cutting fluids have always been critical issues. As product precision requirements continue to increase, the control of environmental stability during the machining process becomes increasingly stringent.

[0003] In traditional machining bases, when faced with poor product sealing during processing, if air leakage occurs at the product edge, a large amount of cutting fluid will be absorbed into the negative pressure device under negative pressure. This not only wastes the cutting fluid but also damages the equipment. Utility Model Content

[0009] Preferably, the inner wall of the second guide hole has an isosceles trapezoidal cross-section, and the cross-section of the plug is also an isosceles trapezoidal, so that the plug can be adapted to seal the second guide hole.

[0013] Figure 1 This is a schematic diagram of the negative pressure valve of a CNC negative pressure drainage base proposed in this utility model when it is closed.

[0014] Figure 2 This is a schematic diagram of the negative pressure valve of a CNC negative pressure drainage base proposed in this utility model when it is open. Detailed Implementation

[0015] refer to Figure 1-2 This utility model proposes a CNC negative pressure drainage base, including: a base body 1, which serves as the basic load-bearing component of the entire drainage base, and has a cavity 2 inside, which plays a key role in collecting cutting fluid.

[0016] A first flow guiding assembly is provided on the base 1, which includes multiple first guide holes 3. These first guide holes 3 are arranged in an array with equal spacing on the base 1, and the bottom of each of the multiple first guide holes 3 is connected to the interior of the cavity 2. During product processing, cutting fluid can flow into the cavity 2 through these evenly distributed first guide holes 3, achieving initial collection of cutting fluid. The design of the equal-spacing array ensures that the cutting fluid can flow evenly across the entire surface of the base 1, avoiding problems caused by local accumulation.

[0017] A drainage groove 9 is provided at the bottom of the base 1, and the bottom of the cavity 2 is connected to the drainage groove 9 through a second flow guiding assembly. The second flow guiding assembly includes a second guide hole 6, which is coaxially arranged with the cavity 2. This coaxial arrangement ensures that the cutting fluid, after accumulating in the cavity 2, can flow to the second guide hole 6 along the shortest path. A plug 8 is movably installed between the second guide hole 6 and the drainage groove 9. A groove 7 is also provided at the bottom of the base 1. The drainage groove 9 is horizontally arranged, and the groove 7 is located on the inner wall of the drainage groove 9, and is coaxially arranged with the second guide hole 6. The plug 8 is movably installed on the groove 7. The inner wall cross-section of the second guide hole 6 is designed as an isosceles trapezoid, and the cross-section of the plug 8 is also an isosceles trapezoid. This shape design allows the plug 8 to achieve a tight fit when sealing the second guide hole 6, effectively preventing the cutting fluid from leaking when it is not needed. Meanwhile, the height of the plug 8 is greater than the height of the drainage groove 9. This design ensures that the plug 8 can stably seal the second guide hole 6 under normal processing conditions, preventing the plug 8 from detaching from the groove 7.

[0018] A pressure assembly is also provided on the base 1, which is connected to the inner top of the cavity 2. The pressure assembly includes a pipe 4 and a negative pressure valve 5. The pipe 4 is securely installed on the base 1, and its end is connected to the inner top of the cavity 2. The negative pressure valve 5 is installed on the pipe 4. When the operator opens the negative pressure valve 5, the pipe 4 connects the cavity 2 to an external negative pressure source, creating a negative pressure environment inside the cavity 2. At this time, under the action of negative pressure, the plug 8 is adsorbed at the second guide hole 6, thereby sealing the second guide hole 6 and ensuring that the negative pressure inside the cavity 2 is stable during the machining process. The cutting fluid will not flow into the drainage groove 9 through the second guide hole 6. When the product processing is completed, the operator closes the negative pressure valve 5, the negative pressure in the cavity 2 disappears, and the plug 8 falls from the second guide hole 6 into the tank 7 under its own gravity. At this time, the second guide hole 6 is connected to the drainage tank 9, and the cutting fluid accumulated in the cavity 2 can flow into the drainage tank 9 through the second guide hole 6, and then be discharged to the machine water pump for recycling. The pipe 4 is connected to the inner top of the cavity 2, which can prevent the cutting fluid from being absorbed into the negative pressure device under the action of negative pressure.

[0019] This technical solution demonstrates significant practical application benefits. By improving the design of the CNC negative pressure drainage base, the problem of cutting fluid waste is effectively and precisely solved, substantially reducing production costs. Simultaneously, this solution improves resource utilization efficiency in the production process, reduces damage to equipment caused by cutting fluid leakage, extends equipment lifespan, and lowers maintenance costs. Furthermore, reducing cutting fluid waste and leakage improves the production environment and reduces environmental pollution risks, resulting in excellent economic and environmental benefits.
