But no matter what kind of control method, the flowing water will inevitably produce ripples, which will produce different reflectivity and refractive index for light, and the processing effect will still be greatly affected

Embodiment Construction

[0030] figure 1 The structure shown is a laser shock peening device for the falcon part of an aircraft blade that is relatively complete and suitable for automatic laser strengthening. It should be known that, for example, the falcon part 5 of the blade 2 often needs to be sprayed with absorbing paint, such as black paint, and then painted on it. Laser strengthening is performed, while the painting itself can be done separately.

[0031] Similarly, for example, the tooling 14 can also be made separately and assembled on the falcon portion 5 of the blade 2. Therefore, in the embodiments of the present invention, if a strong automatic completion rate is not considered, more Realization can assist configuration, but does not constitute a necessary technical feature.

[0032] In the most basic implementation, it is a new constraint configuration compared to the traditional constraint form. As a basic laser shock peening device for the falcon part of an aircraft blade, it should a...

Abstract

The invention discloses a laser shock peening device of an airplane blade tenon. The laser shock peening device comprises a workpiece clamp, a tool, a first mechanical arm and a laser device. The workpiece clamp is used for clamping of a to-be-strengthened airplane blade. The tool is transparent, a cooperation portion of the tool is matched with the airplane blade tenon, and after absorption paintis sprayed to the to-be-strengthened airplane blade tenon, the tool is mounted on the airplane blade tenon. The first mechanical arm is used for driving the workpiece clamp. A laser head of the laserdevice is used for laser shock peening of the airplane blade tenon. Based on the laser shock peening device, the strengthening effect can be guaranteed easily.

Description

technical field [0001] The invention relates to a laser shock strengthening device for the falcon portion of an aircraft blade. Background technique [0002] Aircraft blades are particularly important functional components in the aviation field. Due to the relatively high operating temperature and relatively high working pressure of the aircraft engine, the falcon part of the blade, which is the connection between the blade and the impeller shaft, is prone to fatigue and cracks will eventually lead to blade failure. As a new surface treatment technology, laser shock strengthening has significant effects in improving the fatigue life of materials, suppressing crack initiation, and improving wear resistance. It is difficult for the laser to process narrow curved surface positions when processing by the method, so there are certain difficulties. [0003] Chinese patent document CN103468925A discloses a laser shock strengthening method and device for blade tenon and groove bott...
