Description

Technical Field

[0001] The utility model relates to the technical field of cooling spraying devices, in particular to a cooling liquid spraying device for a numerically controlled machine tool. Background Art

[0002] The coolant spraying device of CNC machine tools is mainly composed of a control panel, a cutting device, a driving device and a cooling device.

[0003] In the prior art, when a cutting device is used to split metal, high temperature and residue are usually generated. High temperature will cause thermal expansion of the material, thereby changing the size and shape of the machine equipment, and causing a loss of precision. Residues accumulate on the surface of the equipment for a long time, affecting its use, so it is necessary to cool down and clean it in time. However, the traditional cooling device uses a spray nozzle to cool the machine. However, due to the large water pressure, the spray nozzle position will be offset, causing the coolant to not be effectively sprayed onto the machine, resulting in a poor cooling effect. In addition, the equipment needs to be cleaned during cooling, and manual cleaning is inefficient and inconvenient.

[0004] Therefore, it is necessary to provide a new cooling liquid spraying device for numerically controlled machine tools to solve the above problems. Utility Model Content
