Vertical overturning laser peening forming device for integral aircraft wing panel and processing method

Abstract

The invention discloses a vertical overturning laser peening forming device for an integral aircraft wing panel. The device comprises an overturning base, an overturning worktable, a telescoping hydraulic cylinder, a slide rail controller, a movable slide rail, a seven-degree-of-freedom laser peening unit, a laser peening unit system host, a total system host, an image processing host, a three-degree-of-freedom optical in-situ measurer and panel clamping units. The invention further discloses a processing method. For the method, area-separated laser peening forming and forming precision optimization are performed firstly under assistance of an online in-situ measurement technology through geometric shape analysis and equal-strength area division of the panel, then integral laser peening forming and area repair of the panel are performed, and finally, forming dimensions are detected. Compared with the prior art, forming of integral aircraft wing panels with various dimensions and complex curved surfaces can be realized, the laser peening forming device has the characteristics of high dimension adaptability, large forming curvature, controllable forming precision, high workpiece surface quality and the like, and long service life and high-precision forming of the panel are realized truly.

Description

technical field [0001] The invention relates to the technical field of aerospace manufacturing, in particular to a laser shot peening forming device and a processing method for the integral wall plate of a vertical flap wing. Background technique [0002] The integral panel forming of the wing is a key point in modern aircraft manufacturing technology, which marks the manufacturing level of a country's aerospace technology. In today's world, only the Boeing Company of the United States and the Airbus Company of the European Union have mastered the special forming technology of the supercritical wing integral panel, and have successfully applied it to advanced civil aircraft such as B787 and A380. [0003] At present, the special forming technology mainly includes mechanical bending, aging forming and mechanical shot peening. [0004] Due to the long service life of important bearing capacity parts of civil aircraft, mechanical press bending is generally not used as the main...
