[0021] Wherein the same reference numerals in the drawings all refer to the same parts.

[0022] like Figs. 1-2 As shown, this utility model provides a cooling device for a CNC grinding machine used for tool processing, including a device body 1, which includes:

[0023] The grinding box 2 includes a grinding assembly 201, a clamping assembly 202, and a spraying assembly. The spraying assembly includes a pressurizing assembly 203 and nozzles 204. The nozzles 204 are installed at both ends of the grinding assembly 201, and the clamping assembly 202 is installed on the bottom side of the grinding assembly 201. The grinding box 2 contains the grinding assembly 201, the clamping assembly 202, and the spraying assembly. The spraying assembly includes a pressurizing assembly 203 and nozzles 204. The nozzles 204 are installed at both ends of the grinding assembly 201 and are used to spray coolant during grinding. The clamping assembly 202 is installed on the bottom side of the grinding assembly 201 and is used to fix the cutting tool.

[0024] Water tank 3 is installed at the bottom of grinding box 2. Water tank 3 contains coolant and includes a plate heat exchanger 302 and a water pump 303. The water pump 303 is installed at the bottom of the plate heat exchanger 302, and connecting pipes 304 are installed at both ends of the water pump 303. A collection hopper 301 is installed at the top of the plate heat exchanger 302. Water tank 3 is installed at the bottom of grinding box 2 and is used to store coolant. The plate heat exchanger 302, located inside water tank 3, is used to cool the circulating coolant. The water pump 303, installed at the bottom of the plate heat exchanger 302 and connected to connecting pipes 304 at both ends, is used to draw coolant.

[0025] Screen 4 is installed at the connection between the grinding box 2 and the water tank 3 to filter impurities in the coolant, so that the coolant can be recycled and reused.

[0026] Furthermore, a concentrated hopper 301 is installed at the bottom of the mesh 4. The concentrated hopper 301 is funnel-shaped, and its bottom end is connected to the plate heat exchanger 302 to concentrate the filtered coolant into the plate heat exchanger 302.

[0027] Furthermore, the connecting pipe 304 penetrates the outer shell of the grinding box 2 and connects to the nozzle 204, and the water pump 303 is connected to the nozzle 204 through the connecting pipe 304.

[0028] Furthermore, a temperature sensor is installed inside the water tank 3 to monitor the temperature of the coolant in real time and ensure the cooling effect.

[0029] Furthermore, there are two clamping components 202, which are respectively installed on the left and right sides of the top of the mesh 4, and the left and right clamping components 202 are arranged in a symmetrical structure.

[0030] The specific steps are as follows: During grinding, the pressurization component 203 is activated, spraying coolant through nozzles 204 onto the grinding area to cool the tool and workpiece. Used coolant flows into a strainer 4, filtering out impurities. The filtered coolant then enters the water tank 3 and is cooled by the plate heat exchanger 302. The cooled coolant is then pumped by the water pump 303 and transported back to the nozzles 204 via connecting pipes 304, achieving recycling. A temperature sensor monitors the coolant temperature in real time, and the control system adjusts the operating status of the plate heat exchanger 302 and the water pump 303 to ensure effective cooling.

[0031] This invention relates to a cooling device for a CNC grinding machine used in tool processing. By spraying coolant through nozzle 204, the high temperature during the grinding process is effectively reduced, preventing damage to the tool and workpiece due to overheating and thus extending their service life. Secondly, the mesh screen 4 effectively filters impurities from the coolant, ensuring the cleanliness of the recovered coolant and improving its recycling rate. Combined with the use of a plate heat exchanger 302 and a water pump 303, the coolant can be rapidly cooled before use, ensuring it remains at a low temperature throughout the entire processing, further enhancing the cooling effect.
