Abstract

The utility model relates to airplane manufacture technology and provides a novel location mechanism for an airplane stringer and particularly for location of the airplane stringer. The location mechanism for the airplane stringer is characterized by comprising a stringer tightly-pressing device and a stringer location plate. The stringer location plate is provided with a set of stringer location groove openings. The stringer tightly-pressing device is fixed on the stringer location plate. A stringer tightly-pressing point on the stringer tightly-pressing device coincides with a stringer location groove opening point on the stringer location plate. The location mechanism for the airplane stringer has the advantages that structure is light in weight and exquisite, the weight is no more than 1 kilogram, use is flexible, better generality is possessed, the number of special location tightly-pressing devices used by a traditional plate assembly clamp device is reduced, and a solution is provided for places where space is small and the special location tightly-pressing devices can not be arranged.

Description

The detent mechanism of the long purlin of a kind of aircraft

Technical field

The application relates to the aircraft manufacturing technology, and the location that is in particular the long purlin of aircraft provides a kind of new long purlin detent mechanism.

Background technology

Aircraft target ship mainly is made up of covering and long purlin, and aircraft target ship is made in the assembling process, is one of key factor that influences the aircraft target ship assembly quality with the accurate location of growing purlin and covering.Long purlin, location all needs special-purpose positioning fixture usually, but owing to the variation of aircraft configuration, and some adjacent long purlins different in size causes; Problem is that conventional positioning fixture location can't be used in short long purlin, and for location, short long purlin, existing wallboard assembling jig need design various switching locator and locate long purlin on framework; Its drawback is more: design, the manufacturing cycle is long; Use inconvenience, do not have versatility, can only be used for the long purlin location and installation of certain.

Summary of the invention

The application's purpose is to provide the detent mechanism of the long purlin of a kind of aircraft.

The localization method of the long purlin of the aircraft that the application adopts; Be based on relative position relation between known long purlin to be positioned and two the oriented long purlins, propose a long purlin detent mechanism; Be provided with a plurality of long purlins anchor point in the detent mechanism of long purlin; This length purlin anchor point has solidified two relative position relations of having located long purlin and long purlin to be positioned; Two oriented long purlins are fixed on the corresponding anchor point of long purlin detent mechanism, longer purlin to be positioned are fixed on the location of realizing long purlin to be positioned on the corresponding anchor point of long purlin detent mechanism.

The long purlin of above-mentioned aircraft detent mechanism; It is characterized in that containing long purlin compactor and long purlin location-plate; Described long purlin location-plate is provided with a group leader purlin locating notch; Long purlin compactor is fixed on the location-plate of long purlin, the long purlin on the compactor of long purlin compress a little with length purlin location-plate on the locating slot stomion coincidence of long purlin consistent.

During use, will grow the purlin detent mechanism and be fixed on the oriented long purlin, locate the position of long purlin to be positioned again by long purlin detent mechanism.

The application's advantage is that the structure light weight is small and exquisite; Weight is no more than 1Kg; Can use flexibly, and have good versatility, reduce the special-purpose set packer of One's name is legion in traditional wallboard assembling jig; Particularly narrow and small to the space, the place that special-purpose set packer can't be set provides the way that solves.

Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

Description of drawings

Fig. 1 is the aircraft target ship structural representation.

Fig. 2 uses sketch map for long purlin detent mechanism.

Fig. 3 is the long purlin of an aircraft detent mechanism structural representation.

Fig. 4 is the compactor structural representation.

Numbering explanation among the figure: 1 covering; 2 have located long purlin; 3 long purlins to be positioned; 4 long purlin detent mechanisms; 5 locating notches; 6 long purlins compress a little; 7 long purlin compactors; 8 long purlin location-plates;

The specific embodiment

Referring to accompanying drawing, the aircraft target ship among Fig. 1 is made up of covering 1 and the long purlin that is riveted on its inboard, and there is fixing position relation three adjacent long purlins, and wherein have good positioning in two long purlins, and the 3rd long purlin needs the location.See Fig. 2; The application is solidified the distance and position between adjacent three long purlins through long purlin detent mechanism 4; Be crimped on the locating notch 5 of long purlin detent mechanism 4 locating long purlin 2; Long purlin through long purlin compactor 7 compresses a little 6 and will locate long purlin 2 and compress, and longer purlin 3 to be positioned is fixed on the location of realization long purlin to be positioned on the corresponding anchor point of long purlin detent mechanism 4.

See Fig. 3 and Fig. 4; The application's long purlin detent mechanism 4 is by containing long purlin compactor 7 and long purlin location-plate 8; On long purlin location-plate 8, be provided with a group leader purlin locating notch 5, by the distance and position that long purlin locating notch 5 solidifies between the adjacent long purlin, long purlin compactor 7 is common normal structures; Long purlin compactor 7 preferably is fixed in the middle of one group of parallel long purlin location-plate 8, the long purlin on the compactor of long purlin compress a little 6 with long purlin location-plate 8 on 5 coincidences of long purlin locating notch consistent.

Claims
