Technical Field
The application belongs to the field of measurement in aircraft assembly production, and relates to an aircraft assembly part pose detection measuring connector capable of being quickly positioned and connected.
Background
In the assembly production process of an airplane, the attitude of a large part needs to be detected in real time when the large part is in butt joint, the attitude is not adjusted continuously until the large part meets the theoretical attitude, a measuring joint is used as a reference support for fixing a laser tracker reflection target on the outer surface of the airplane part and is an indispensable important part of a measuring process, the existing measuring joint is a single-lug type joint with a curved surface mounting plate, the measuring joint needs to be positioned and installed through a special positioner in the assembly stage of the part, a special mounting hole is drilled in the surface of the airplane part and used for fixing the measuring joint, the measuring joint is in a T-shaped structure and needs to be subjected to line control processing after precision casting, and the measuring joint is different in curvature in different areas of the outer surface of the airplane part, the measuring joint is different in different areas, the universality is poor.
Disclosure of Invention
In order to solve the problems, the invention aims to provide an aircraft assembly part pose detection measuring joint which can be reliably connected with a product and can reliably fix a laser tracker reflection target, is strong in universality and small in occupied space, and can be quickly disassembled.
In order to achieve the above purpose, the following technical scheme is adopted to realize the purpose:
the utility model provides an aircraft assembly part position appearance detects measuring connector, including the step axle, lock nut, magnetic block, the step axle is a tertiary step axle of making with magnetic material, lotus petal form alleviates the recess is opened to step axle top, alleviate the recess bottom and open a perpendicular blind hole chamber, blind hole intracavity is equipped with a magnetic block, the magnetic block after the installation does not bulge and alleviates the recess bottom, alleviate the recess side and make the spherical cambered surface, spherical cambered surface and laser tracker reflection target excircle phase-match, the magnetic block in the blind hole intracavity passes through magnetic attraction, adsorb the reflection target reliably on the spherical cambered surface. The middle part of the step shaft is matched with the mounting hole of the fastener on the outer surface of the airplane component and used for fixing the measuring joint on the outer surface of the airplane component by the mounting hole of the fastener of the airplane. The tail part of the step shaft is provided with a taper, the step shaft is matched with a locking nut for use, the locking nut is made of a magnetic material, a through hole with the taper is formed in the step shaft, the locking nut and the step shaft are integrally fixed on the outer surface of an airplane part through magnetic attraction, and the length of the taper fit can be automatically adjusted according to the thickness change of an airplane interlayer.
The beneficial effect of this application lies in: 1) the step shaft can be made into different specifications according to the existing holes on the aircraft skin, so that the universality of the measuring joint is enhanced; 2) the locking nut is made of a magnetic material, so that a time-consuming thread screwing process in the installation process of the measuring connector is omitted; 3) the measuring joint has the advantages of simple integral mechanism, low manufacturing cost and short processing period.
The present application will be described in further detail with reference to the accompanying drawings of embodiments
