Mechanical cutting device for aircraft skin

Abstract

The invention provides a mechanical cutting device for an aircraft skin, and relates to the field of repairing of the aircraft skin. The mechanical cutting device for the aircraft skin comprises a scale handle, a power device and a cutting tool. The mechanical cutting device for the aircraft skin is characterized in that the device is positioned on a fixed skin during use; the scale handle slides to indicate the radius of the skin needing to be cut; an operating handle is downwards pressed, and then the power device downwards moves; a bevel tooth sleeve and a bevel gear are separated; a power wire is connected to switch on a power supply; the cutting tool is driven by the power device to cut the skin; the skin cutting intensity is determined by controlling the downward pressing force of the operating handle; after the skin is cut, the power supply is switched off; the pressure on the operating handle is released while the rotating speed is turned into low speed; the power device is rebound through an elastic device; and the bevel gear and the bevel tooth sleeve are engaged to lock the rotating of a driving shaft. With the adoption of the device, aircraft crews can quickly cut the skin without influencing the skin material performances.

Description

technical field [0001] The invention relates to the field of aircraft skin maintenance, in particular to mechanical cutting during aircraft skin maintenance, and is suitable for circular cutting of skins with various diameters. Background technique [0002] For a long time, skin cutting in the process of aircraft damage repair has been mainly done manually, with low precision and difficult marking. After marking the line by hand, the machine maintenance tool is used to manually cut along the shape of the cutting line, which is inconvenient to operate and affects the accuracy and progress of the repair. When the workload of maintenance tasks is heavy for maintenance personnel, it is very easy to cause the situation that the tasks cannot be completed. [0003] Some organizations invented the use of laser cutting devices to cut the skin. However, although laser cutting is convenient and fast, it will cause large internal stress after cutting the skin, reduce the life of the ma...
