Description

Technical Field

[0001] This utility model relates to the field of laser shock peening equipment technology, and in particular to a laser head for laser shock peening of the shielded part of an integral bladed disk. Background Technology

[0002] Laser shock peening is a high-tech method that uses plasma shock waves generated by a powerful laser beam to improve the fatigue resistance, wear resistance, and corrosion resistance of metallic materials. Compared with existing surface strengthening methods such as cold extrusion and shot peening, it has received widespread attention and research since its inception due to its outstanding advantages, including non-contact operation, absence of a heat-affected zone, high controllability, and significant strengthening effect.

[0003] The integral bladed disk (IBD) integrates the blades and disk into a single component, replacing the traditional connection structure of blade tenons and disk tenons with locking plates. This improves the engine's aerodynamic efficiency, thrust-to-weight ratio, and reliability. Traditional strengthening techniques for individual blades include shot peening. However, shot peening is difficult to implement on irregularly shaped parts, easily causes deformation of thin-walled components, and can affect surface roughness and dimensions. Laser shock peening can overcome the shortcomings of shot peening, and is particularly suitable for integral bladed disks with complex structures. However, existing laser heads used for laser shock peening of shielded areas of integral bladed disks suffer from insufficient stability when stationary due to their considerable length.

[0004] How to improve the stability of the laser head for laser shock enhancement without affecting its movement, so that it can be used in a variety of scenarios and reduce the probability of damage, has become a technical problem that needs to be solved.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
