Abstract

The invention discloses a blisk single-face/double-face laser shock peening light path system, and belongs to the field of blisk laser shock peening. Four light paths are composed by a light table, a numerical control sliding table, numerical control rotary tables, reflectors, focus lenses, dodging lenses, swing arms, energy meters, a protective plate, a protective cover, a light guide tube and the like. Any one of the four light paths can be manually/automatically selected to work, and the second light path and the fourth light path can be selected to work simultaneously. The first light path and the third light path are focusing light paths, and when laser beams with the diameters being less than 27 mm are input, output laser spots are uniform-light-intensity round light spots with the diameters being 2 mm-5 mm; the second light path and the fourth light path are dodging light paths, and when the laser beams with the diameters being less than 27 mm are input, uniform-light-intensity square light spots with the side lengths being 2 mm-5 mm are output. The blisk single-face/double-face laser shock peening light path system is simple in structure; when the blisk single-face/double-face laser shock peening light path system is used, production efficiency is improved, and uniformity and stability of laser shock peening quality are guaranteed.

Description

technical field [0001] The invention belongs to the field of laser shock strengthening processing of integral blisks, and in particular relates to an optical path system for single / double-sided laser shock strengthening of integral blisks applied in aeroengines. Background technique [0002] The blade is the main component of energy conversion in the aero-engine, and it is also one of the most core and key parts, known as the "heart of the heart". In the mid-1980s, in order to reduce the number of parts in the aero-engine, reduce the overall weight and improve the aerodynamic efficiency, thrust-to-weight ratio and reliability of the engine, advanced technologies such as ultra-wide chord, curved-swept blade and narrow flow channel were adopted in the engine design. The overall blisk structure of the aerodynamic layout design. Engine blades often break due to high-frequency fatigue, which directly affects the safety and life of the engine. When encountering the above situati...
