Abstract

The invention relates to an ultrafast laser machining device for blade punching based on a cold machining mode. The ultrafast laser machining device comprises an ultrafast laser system, a light beam shaping part, a laser machining head and a blade clamp and control system. The ultrafast laser system can be a picosecond laser system or a femtosecond laser system. The light beam shaping part comprises a plurality of lens and optical elements. The laser machining head comprises a reflecting device located on the upper portion and a focusing lens located on the lower portion. The blade clamp and control system is used for adjusting the position and posture of a blade accurately.

Description

technical field [0001] The invention relates to the technical field of ultrafast laser processing systems such as picoseconds and femtoseconds, and in particular to an ultrafast laser processing device for punching holes in blades based on cold processing. Background technique [0002] With the rapid development of science and technology, improving the efficiency and thrust-to-weight ratio of aircraft engines is achieved by increasing the temperature of the combustion chamber, because the temperature of the combustion chamber will reach above 1800°C when the engine is working, and this temperature value is the same as that of high temperature resistant single The melting points of turbine blades made of supercrystalline superalloy materials are similar, which shortens the service life of the blades and reduces the performance of the engine, making the blades in an environment with potential safety hazards when they are working. At present, the advanced air film hole cooling ...
