Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a universal nozzle and a riveting jig for a machine tool cooling system. Background Art

[0002] CNC machine tools are prone to generate high temperatures when performing cutting work for a long time, which reduces their service life and affects the processing accuracy. Therefore, it is often necessary to install cooling devices on CNC machine tools. The coolant acts on the workpiece and the tool to reduce the heat generated during processing, thereby extending the service life of the tool.

[0003] At present, cooling devices generally use plastic universal curved tubes and metal nozzles. When used in some machine tool processing equipment that requires ultra-high pressure flushing and cooling, the plastic universal curved tubes are easily deformed under the impact of the internal high-pressure medium, affecting their service life; and the metal nozzles cannot adjust the angle, limiting their application range.
