Abstract

The invention discloses a nail pulling device. The nail pulling device comprises a nail pulling cylinder (1) and a nail pulling rod (2); the nail pulling cylinder (1) is arranged outside the nail pulling rod (2) in a sleeving mode in the radial direction, one end of the nail pulling cylinder (1) is used for abutting against a structure fastened by nails, and the other end of the nail pulling cylinder (1) is provided with a baffle; and one end of the nail pulling rod (2) is provided with a clamping groove for clamping a nail head, and the other end of the nail pulling rod (2) penetrates out ofthe baffle. According to the nail pulling device, the problems that a plurality of connected parts with unopened structure spaces, closed angles and the like exist and fasteners are difficult to dismantle due to interference installation are solved through matching operation of the nail pulling cylinder (1) and the nail pulling rod (2); and moreover, the nail pulling device improves the removal efficiency of the fasteners, avoids possible damage of the connected parts due to the removal of the fasteners, and can greatly reduce the maintenance and repair cost.

Description

technical field [0001] The invention relates to the technical field of aircraft maintenance, in particular to a nail removing device and a using method thereof. Background technique [0002] At present, after the aircraft has been in service for a period of time, it is necessary to carry out corresponding repairs and maintenance, remove some severely worn or corroded fasteners, and replace them with new fasteners. The traditional replacement method: [0003] a. First, use a caliper tool to cut off the nut, and then use a hammer and a pin-like slender metal to knock the fastener from one side of the nut to remove it; [0004] b. First, use a caliper tool to cut off the nut, and then drill part of the material of the core rod of the fastener from the head of the fastener to deform it, and then use a hammer and a pin to fit the fastener from the Tap one side of the nut to remove it. [0005] Since not all aircraft structures have spacious spaces, and most fasteners are instal...
