Abstract

The invention discloses a dismounting device for an airplane wire harness pipe joint. The device comprising an upper clamp, an upper clamping plug, a middle spiral hoop, a lower clamp and a lower clamping plug; the upper clamp is a big-end-up cylinder and is provided with a big-end-up stepped through hole, the side face of the upper clamp is provided with a notch, and the two side faces of the notch are provided with horizontal grooves; the shape of the upper clamping plug corresponds to that of the notch, and protruding edges are arranged on two side surfaces; the middle spiral hoop is formed by spirally dividing a notched circular tube into an upper hoop and a lower hoop; the lower clamp is a big-end-down cylinder and is provided with a through hole with the upper portion and the lower circle coaxial, the notch is formed in the side face of the lower clamp, and horizontal grooves are formed in the two side faces of the notch; the shape of the lower clamping plug corresponds to the notch, and protruding edges are arranged at the positions, corresponding to the horizontal grooves, of the two side faces of the lower clamping plug; and the square column of the upper clamp is inserted into the square hole of the lower clamp. The blank is filled, the operation is simple and convenient, the maintenance cost and risk are low, the disassembly can be quickly and safely completed, and the operation safety and efficiency are guaranteed.

Description

technical field [0001] The invention relates to a dismantling tool for an aircraft part, in particular to a dismantling device for an aircraft wire harness pipe joint. Background technique [0002] Aircraft wire harness tubes are widely used in the bearing and protection of aircraft wire harnesses, especially the wire harness tubes of the landing gear system in harsh working environments, the metal mesh of the wire harness tubes will be damaged, and sometimes the wire harness tubes The internal wiring harness also needs repair. Wire harness fittings consist of metal bushings, metal snap rings, plastic conduit and metal mesh. The wire harness connector is installed at the end of the wire harness tube, the metal mesh of the wire tube is closed through the metal bushing, and the integrated metal snap ring is firmly fixed on the wire tube connector, and the end of the plastic wire tube is connected to the wire tube connector. Inside and the whole is wrapped in the inside of th...
