Abstract

The invention discloses a laser shock peening system and method for preventing deformation of a blisk of an aero-engine. The system comprises a laser transmitter mechanism; a manipulator; the blade disc clamp comprises a disc body clamp and a blade clamping clamp, and a disc body of the blade disc is fixed to the tail end of the mechanical arm through the disc body clamp; the blade clamping fixture is fixed on a blade of the blade disc, and the blade clamping fixture and the disc body are clamped and fixed; a laser shock peening opening for allowing laser emitted by the laser emitter mechanism to penetrate through is formed in the position, corresponding to the laser shock peening area on the blade, of the blade clamping fixture, and the laser shock peening area comprises a blade back root, a blade basin root, a blade back front edge, a blade basin front edge, a blade back edge and a blade basin rear edge. In the laser shock peening process, the blade is clamped through the blade clamping fixture, so that certain support is provided for the blade, the force arm of the blade is reduced, the purpose of controlling deformation is achieved, and the quality of the blade is guaranteed.

Description

technical field [0001] The invention relates to the technical field of aero-engine integral blisk blade strengthening treatment, and more particularly to a laser shock strengthening system and method for preventing deformation of an aero-engine integral blisk. Background technique [0002] Laser shock strengthening (Laser Shocking Peening, LSP for short) technology, also known as laser shot peening technology. When a laser with high power density (GW / cm order) and short pulse (10-30ns order) acts on the energy absorbing coating coated on the metal surface through the transparent confinement layer, the coating absorbs the laser energy and rapidly vaporizes And almost simultaneously formed a large number of dense high temperature (>10K), high pressure (>1GPa) plasma. The plasma continues to absorb laser energy and rapidly heat up and expand, and then explode to form a high-intensity shock wave that acts on the metal surface. When the peak pressure of the shock wave exc...
