Drilling device for aircraft panel skin

Abstract

The invention relates to a drilling device for aircraft panel skin and belongs to the technical field of structural design. The device comprises a guide rail base body, a drill bushing base body and apositioning mechanism, wherein a guide rail and a hole forming groove are formed on the guide rail base body, the guide rail is arranged on an upper surface of the guide rail base body and arranged along the center line of the guide rail base body, the hole forming groove penetrates through the guide rail and a bottom face of the guide rail base body, axial directions of the two are consistent, and a bottom face of the guide rail base body is matched with the aircraft panel skin, the drill bushing base body is provided with a drill bushing and a drill bushing hole, the drill bushing is installed in the guide rail and can slide along the guide rail, the drill bushing hole penetrates through the axis of the drill bushing and is communicated with the hole forming groove, and a positioning mechanism is used for fixing the drill bushing base body to the guide rail base body. The device is advantaged in that 1, an application range is wide; 2, a repeated utilization rate is high; 3, interchangeability is good; 4, flexibility is high; and 5, drilling precision is improved, manufacturing cost of large special equipment can be saved, and development cost of newly-researched products is effectively reduced.

Description

technical field [0001] The invention relates to a hole-making device for an aircraft siding-like skin, and belongs to the technical field of structural design. Background technique [0002] Due to the high fatigue strength and long service life of the newly developed aircraft products, a large number of new connection standards such as high-lock bolts are used for the upper and lower wall panels of the aircraft wing, the upper and lower wall panels of the horizontal stabilizer, and the left and right side wall panels of the vertical tail. Parts, which are characterized by large radius of curvature, approximate plane, a large number of connecting parts on the skin surface, regular arrangement, high precision of center distance between holes, high requirements of hole diameter precision and roughness, for thick-walled plate stacking When making holes, the verticality of the holes is required to be high. [0003] There are two traditional methods for locating and making holes ...

AI Technical Summary

Problems solved by technology

But its disadvantage is that the number of guide bushing holes on the drilling template is small, and the distance between the guide bushing holes is limited, the drilling efficiency is not high, and the usable range is small

[0004] For high-precision hole-making of wall panels and skins, large-scale special-purpose machine tools and robots are also used at home and abroad to make precise holes, but the investment cost of special equipment is high.
