Fly-cutting tool of honeycomb plate for inner decoration of airplane

Abstract

A fly-cutting tool of a honeycomb plate for inner decoration of an airplane comprises the honeycomb plate, a lower end driving rod, an upper end driving rod, two upper cutting sheets, two lower cutting sheets, cutting sheet driving devices, and a limiting device arranged on the honeycomb plate, wherein the upper cutting sheets and the lower cutting sheets which are in a folding and storing state, and the lower end driving rod are vertically inserted into through holes in the honeycomb plate, and the upper end driving rod, relative to the honeycomb plate, is kept in a vertical state through the limiting device after inserting into the corresponding through hole; a pneumatic drill connecting rod is fixed to a pneumatic drill clamp in order to obtain rotating power; the lower cutting sheets and the upper cutting sheets are driven through the cutting sheet driving devices to fold and can be unfolded to form a parallelogram together, thus forming a cutting body which is vertical to the driving rods; a pneumatic drill can supply power to drive the corresponding driving rod to rotate to cut and break a honeycomb structure so as to form a cylindrical cavity, and as a result, the fly-cutting purpose can be achieved. The fly-cutting tool is convenient and simple to operate; cutting parts are regular; therefore, the processing quality can be improved, and the labor intensity can be reduced.

Description

technical field [0001] The invention relates to the technical field of cutting tooling, in particular to a fly-cutting tooling for aircraft interior trim honeycomb panels. Background technique [0002] When repairing or replacing the interior honeycomb panel of the Hawker 4000 aircraft, it is necessary to select a position on the original honeycomb panel in advance to destroy and remove the honeycomb core structure to form a cylindrical cavity and inject resin to form an anchor bolt and then drill out the fastening After the parts are connected, the process of cutting the honeycomb core structure is called "fly cutting". [0003] At present, workers do not have effective tooling equipment to complete this work. The more common method is to drill a small hole on the upper surface of the honeycomb structure and then insert the L-shaped thin steel rod and fix it to the pneumatic drill bit holder. Powered by a pneumatic drill to complete the destructive removal of the honeycomb...

Problems solved by technology

[0004] This process is easy to implement, but because the L-shaped steel thin rod has no positioning support point, the concentricity of the installation hole is poor, which eventually leads to irregular cavity area after fly cutting, difficult to control the construction quality and easy to cause damage to the surface of the upper and lower wall panels

The above reasons lead to higher requirements for workers' experience and skill levels in the process of implementing the work according to the current method, which ultimately makes the work cycle longer and the work cost increase
