Description

Technical Field

[0001] The present application relates to the technical field of component cooling, and in particular to a component cooling structure for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are automated machine tools equipped with a program control system. CNC machine tools have solved the problems of complex, precise, small batch, and multi-variety parts processing. They are flexible and efficient automated machine tools, representing the development direction of modern machine tool control technology and a typical mechatronics product. During the operation of CNC machine tools, their components (such as spindles, guide rails, etc.) often generate a lot of heat due to high-speed operation and friction. In order to ensure the accuracy of the machine tool and extend its service life, these components must be effectively cooled. At present, the commonly used cooling structure mainly relies on external coolant circulation or built-in air cooling system. However, the existing coolant circulation system has a complex structure and requires additional pumps and pipelines, which increases the manufacturing cost and maintenance difficulty. Although the air cooling system has a simple structure, the cooling effect is limited in high temperature or high humidity environments, and it is easily affected by dust and cutting fluid, resulting in a decrease in heat dissipation performance.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses a cooling structure for a CNC machine tool component. Figure 1-Figure 2, including a water tank 1, cooling water tanks 2 are symmetrically installed on both sides of the top of the water tank 1, and bellows 3 are installed on the outer walls of the ends of the two cooling water tanks 2 that are away from each other. A fan 10 is installed inside the bellows 3, and a protective cover 4 is connected to the outer wall of the bellows 3 by screws. Air cooling can be performed by the operation of the fans 10 on both sides to accelerate the circulation of air. A top box 5 is fixedly installed at the center of the top of the cooling water tank 2, and a water pipe 6 is installed on the outer wall of the top box 5. One end of the water pipe 6 is connected to an external cooling water pump, and one end of the water pipe 6 extends into the top box 5 and is fixed with a spray pipe 8. A plurality of nozzles 9 are equidistantly arranged at the bottom of the spray pipe 8. Cooling water can be sprayed through the nozzles 9. Water cooling can be performed while air cooling, which greatly improves the cooling effect;

[0020] A cooling chamber 11 is provided inside the two cooling water tanks 2. A spray groove 7 adapted to the spray pipe 8 is provided at the top of the inner wall of the cooling chamber 11. A baffle 12 is connected to the top of the outer wall of the cooling chamber 11 by screws. The setting of the baffle 12 can prevent water from splashing over a large area and facilitate cooling of the components.

[0021] like Figure 3 As shown, a processing table 15 is installed on the top of the water tank 1. The two ends of the top of the processing table 15 are integrally structured with fixed limiting edges 16 to prevent the components from slipping. Guide slopes 17 are provided on both sides of the processing table 15. The waste chips generated by the processing can be discharged to both sides through the guide slopes 17. Drain ports 13 are provided at both ends of the inside of the water tank 1. The drain ports 13 extend to the inside of the cooling water tank 2. An outlet pipe 14 is fixed to the outer wall of one side of the water tank 1 to discharge the sewage generated after cleaning and cooling.

[0022] The implementation principle of a cooling structure for a CNC machine tool component in an embodiment of the present application is as follows: when in use, the CNC machine tool component is placed on a processing table 15 for processing, and at the same time, the fan 10 inside the bellows 3 can be started for air cooling to accelerate the dissipation rate of the external heat of the component. At the same time, the external cooling water pump can be connected through the water pipe 6, and the cooling water is pumped into the spray pipe 8 and sprayed downward through the nozzle 9. At this time, the baffle 12 is used to limit the water flow to prevent the water flow from splashing on a large scale during the falling process. Then the component can be placed in the cooling water tank 2 and flushed with cooling water to wash away impurities such as iron filings on its outer wall. At the same time, the cooling efficiency is greatly improved by the water cooling and air cooling method. The sewage generated by the cooling flows to the internal storage of the water tank 1 through the drain port 13, and can be discharged to the outside through the outlet pipe 14 for subsequent circulation treatment.
