Combined positioning drilling tool for airplane structure

Abstract

The invention relates to combined positioning drilling tool for an airplane structure, belongs to the positioning drilling tools which are designed for modifying the airplane structure, and aims to meet positioning drilling requirements of parts. The combined positioning drilling tool comprises three parts, namely a first sample plate, a second sample plate and a dowel pin, wherein the dowel pin is fixedly arranged on the first sample plate and is used for limiting the up-down position, relative to the first sample plate, of the second sample plate; the second sample plate is arranged on the lower surface of the dowel pin, so that the upper surface of the dowel pin clings to the dowel pin, the edge of the dowel pin clings to the surface of the first sample plate, and the left edge and the right edge of the dowel pin are guaranteed to be aligned to the first sample plate; and an included angle between the first sample plate and the second sample plate is 90 degrees. The combined positioning drilling tool can guarantee positioning precision requirements of parts, and can guarantee relative position precision of holes; and moreover, the tool is simple in structure, can be quickly manufactured, reduce preparation time, is simple and convenient in use, and can meet the refitting needs.

Description

technical field [0001] The invention relates to a combined positioning hole-making tool for an aircraft structure, which belongs to a positioning hole-making tool designed for refitting an aircraft structure to meet the positioning and hole-making requirements of parts. Background technique [0002] The aircraft needs to be installed with components due to mission requirements. Before the components are installed, the structure needs to be refitted and the bracket nuts for fixing the components need to be installed in advance. A total of two components need to be installed in the modified part, and each component is mainly fixed on the supporting plate nut pre-installed on the structure by a total of 4 bolts at the upper and lower parts; and the lower part of the component is provided with a bracket for the bracket The screws are fixed on the bracket nuts on the profiles, and the bracket nuts need to be pre-fixed on the newly added structural profiles according to the instal...

[0006] 3) Since the lower bracket of the finished part is fixed on the newly added structural profile, the angle of the plane where the structural profile is located relative to the plane where the bolt holes of the finished part is located must be guaranteed to be 90 degrees. If the angle is too large, after the finished part If the angle is too small, the rear part of the component will be supported by the bracket and the bolts that fix the component cannot be installed.
