Abstract

The invention relates to the technical field of aircraft assembly, in particular to a portable positioning pin removal device and a using method thereof. The portable positioning pin removal device comprises an outer case, an inner shaft, a base, clamping jaws and force application rods, wherein the inner shaft is in threaded transmission with the outer case; the inner shaft is provided with inner shaft lugs; the force application rods are connected to the inner shaft lugs; the base can realize rotary motion along the outer case; the bottom end surface of the inner shaft is provided with at least one guide groove evenly distributed along the axis; the number of the clamping jaws is the same as the number of the guide grooves; the clamping jaws are provided with clamping jaw bosses; the clamping jaw bosses and the guide grooves form moving pairs; the inner surface of the base is provided with base radial teeth; the lower ends of the clamping jaws are provided with clamping jaw teeth; the base radial teeth are in screw transmission with the clamping jaw teeth; and the front ends of the clamping jaws are provided with arc-shaped wedges. Through the portable positioning pin removal device and the using method thereof, the problems of low efficiency and unstable assembly and positioning of components can be effectively solved. In addition, the labor intensity can be reduced, and the service lives of tools and positioning pins are prolonged.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to a portable positioning pin removal device and a using method thereof. Background technique [0002] In aircraft assembly technology, positioning pins are widely used. Usually, the positioning pin and the positioned part are connected by transition fit. Aircraft structural assembly involves a wide variety of components and a large quantity. During the structural assembly process, positioning tooling and multiple positioning pins are usually used to complete the positioning assembly of components. [0003] In the assembly process of the existing structure, workers first place the parts to be positioned on the positioning tool and adjust their posture so that the position of the parts meets the assembly positioning requirements. Then, the worker inserts the positioning pin into the positioning hole of the given part and the tooling for positioning. After the parts are a...
