Wing spar aligning tooling and aligning method

Abstract

The invention discloses an alignment tool and alignment method for spar automatic hole formation in the technical field of aircraft manufacturing assembly. The tool comprises a vertical rib positioning block and a slide positioning block; the vertical rib positioning block is provided with a locking clamp port clamped on a vertical rib of a spar; the slide positioning block is slidingly connectedwith the vertical rib positioning block, and the sliding direction is consistent with the width direction of the vertical rib; a bias reference hole is formed in one end of the slide positioning block, and exceeds the end surface of the spar; and the axis of the bias reference hole is perpendicular to the inner surface of an edge bar of the spar. The alignment tool converts a control surface of the vertical rib to a visible position of hole forming equipment through a reference change mode; and through the extension characteristic of the vertical rib along with the spar, the automatic hole forming equipment can easily position the position of the bias reference hole through a visual alignment function to judge the difference between the position of the vertical rib and a theoretical position, so that a local coordinate system is corrected, the hole forming precision is finally improved, and the spar automatic hole forming operation is achieved.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing and assembly, in particular to an alignment tool and an alignment method for automatic hole-making of a wing spar. Background technique [0002] At present, automatic hole-making equipment is widely used in the wing box assembly process in the industry to improve production efficiency and product quality. For a long time, it has been impossible to realize automatic hole making on the edge of the spar. The reason is that the spar is generally long, about 20 meters, and it will be partially extended after shot peening. The extension is several millimeters, and the extension of each section is different. . If the hole-making equipment cannot accurately measure the extension of the spar, it will cause a deviation in the hole-making benchmark, which may cause a large deviation in the hole-making position and cause the spar to be scrapped. Therefore, at the present stage, the hole makin...
