Embodiment Construction

[0025] Refer to the instructions attached figure 2 , An aircraft spoiler embedded nut removal tool, which includes a plate-shaped base 5 and a pair of removal members with outhanging rods 8 arranged at the front end of the base perpendicular to the surface of the base, wherein two The pitch a of the outriggers is 0.52 to 0.56 inches, the length h of the outriggers is 0.36 to 0.40 inches, and the diameter d is 0.094 inches.

[0026] Preferably, the distance between the two outriggers is 0.55 inches, and the length of the outriggers is 0.38 inches.

[0027] In order to meet the requirements of use and make the structure of the base as compact as possible, the base is selected from materials with a yield strength greater than 60Ksi and a tensile strength greater than 70Ksi, and the outstretching rod is selected from high-speed steel. Of course, the base is mainly held by hand. The feeling of holding is very important and the size should not be too small. Therefore, the material of th...

Abstract

The invention discloses a detaching tool for embedded nuts of a plane spoiler and a detaching method applying the same. The detaching tool comprises a plate-shaped base and a pair of removing members with external extending rods, wherein the removing members are arranged at the front end of the base and perpendicular to a base plate surface, the gap of the two external extending rods is 0.52-0.56 inches, and the length of the external extending rod is 0.36-0.40 inches and the diameter thereof is 0.094 inches. According to the detaching tool and the detaching method of the invention, the removing efficiency of the embedded nuts can be improved without damaging the spoiler.

Description

Technical field [0001] The invention relates to a disassembly tool and a disassembly method for an embedded nut of an aircraft spoiler. Background technique [0002] Embedded nuts are widely used in aircraft spoilers. Take the B737 series aircraft as an example. There are 10 spoilers on the left and right wings, and each spoiler has about 40 to 50 embedded nuts. See the instructions attached figure 1 The spoiler is a composite honeycomb sandwich structure. The embedded nut 3 passes through the skin 1 and is glued into the honeycomb 2 by resin. If the spoiler needs to be repaired, the embedded nut in the corresponding area needs to be removed. [0003] Due to the firmness of the resin and the fragility of the honeycomb sandwich structure, removing the embedded nut is very time-consuming and laborious, and it is extremely easy to cause deformation of the spoiler and damage to the separation layer. There are currently two common practices: [0004] One is to use circlip pliers to remo...
