Abstract

The invention provides an inner hole laser quenching head and a quenching method. After the laser beam passes through the collimating lens, the laser beam passes through the first full reflection lens and the full reflection focusing lens to form an annular laser beam, and then enters the inner hole parts that need to be quenched. , through the second full reflection lens in the inner hole part, the ring laser beam is irradiated on the inner wall of the inner hole part, so as to achieve the purpose of simultaneous laser quenching on the inner wall circumference of the inner hole part. The moving device 7 of the inner hole is consistent with the movement of the external laser quenching head.

Description

technical field [0001] The invention relates to the field of laser quenching, in particular to an inner hole laser quenching head and a quenching method thereof. Background technique [0002] Laser quenching technology uses a high-energy laser heat source to instantly heat the surface of the material above the phase transition temperature point. As the material cools below the phase transition temperature point, the austenite structure transforms into a martensite structure, thereby hardening the material surface. a method of [0003] The use of laser quenching technology has a short process cycle, small workpiece deformation, clean working environment, and no further machining is required after treatment. It is especially suitable for surface treatment of parts with high precision requirements. It is a green and environmentally friendly quenching process. [0004] At present, due to the limitation of the size of the laser head, it is impossible to achieve laser quenching o...
