Abstract
The invention discloses a positioning fixture structure for a plane spherical frame. The structure is characterized in that: an inner pallet is used for supporting and positioning a sphere surface; a marking stripe rotates around a sphere center of the spherical frame to realize positioning by marking of all the external radiation strips; and a quick-detachable hub and a flexible compressing belt compress the sphere surface to replace a conventional outer pallet. The structure increases open space in the process of riveting, is convenient to take products off shelves, reduces labor intensity, improves productivity, and can be widely applied to positioning of a structure similar to the plane spherical frame structure.
Description
Technical field
The present invention relates to the frock furniture in the Aircraft Production, particularly a kind of positioning fixture at the riveted joint of external radiation bar formula sphere frame.
Background technology
The sphere frame is the boundary frame of air-tight cabin and nonpressurized interior on the airframe, is one of assembly important in the aircaft configuration, and radiation item formula and two kinds of forms of external radiation bar formula mainly comprise parts such as covering (sphere frame covering), radiation item, stiffening profile in being divided into.When the sphere frame was made in assembling, very difficult to the line location of sphere frame covering and radiation item, the location more complicated of external radiation bar need the radiation item quantity of riveted joint many, and because sphere frame centre of sphere place opening is less, the space that keeper is set was very limited.
The primary structure of the riveted joint anchor clamps of traditional sphere frame external radiation bar is outer card plate location in adopting, the shape clamp supports covering in promptly adopting, the profile clamp compresses covering, profile clamp, two ends block piece or line part are set with location external radiation bar, the multiple tracks clamp is constantly shifted one's position or is only located the radiation item two ends.The clamp that traditional location structure needs is many, operation is many, and workman's complicated operation, space are little.
Therefore, need a kind of more novel structure of development, solve the problems referred to above.
Summary of the invention
The purpose of this invention is to provide a kind of novel sphere and confine position fixture, solve aircraft sphere frame external radiation bar when the riveted joint of location, anchor clamps location structure complexity, problem such as operation is many, the operating space is little.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
Sphere is confined position fixture, by the spherical support body that support frame, center support, end frame annular slab, interior shape clamp are formed, it is characterized in that being provided with flexible holddown belt and radiation item chalker on the anchor clamps center support and between the end frame annular slab.
The invention has the advantages that the interior shape of covering of utilizing existing spherical support clamp body to support the location sphere frame, utilization is radially flexible holddown belt alternative structure complexity of center, bulky profile clamp with centre of sphere place, adopt the radiation item chalker of clock and watch pointer-type to carry out the laying-out for assembling location, simplified clamp structure greatly, very easy to use.
Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

The specific embodiment
Referring to Fig. 1, Fig. 6, formed anchor clamps spherical support body by jig frame 4, anchor clamps center support 3, end frame annular slab 2, interior shape clamp 1, with shape in the covering of interior shape clamp 1 support location sphere frame, with centre of sphere (see figure 3) place is the center, position along radiation item stretches out, the locating hole of sphere frame is set in the suitable position of interior shape clamp, is used for accurately locating the covering position.
Referring to Fig. 1, Fig. 3, Fig. 4, Fig. 6, the radiation item of sphere frame adopts the form of line location to determine rigging position among the embodiment.In anchor clamps center support 3 places, be provided with a rotating shaft fixed cover 17 concentric on shape clamp 1 termination with the sphere frame centre of sphere, establish rotating pin 10 in the cover, be connected with the flexible lineation band on the rotating connector 11 of this bearing pin outer end, this scribe bands fixed cover 17 centers is around the shaft rotated, its outer end and scribe bands stop 9 overlap joints that are fixed on the anchor clamps end frame annular slab 2.During line, at the radiation item of diverse location, only need the rotation scribe bands, on the scribe bands by piece 8 and scribe bands stop 9 fixing after, the locating surface position of drawing each root radiation item, the workman just can position riveted joint according to the position of drawing good radiation item.
Referring to Fig. 1, Fig. 2, Fig. 4, Fig. 5, adopt the flexible holddown belt of band quick-release wheel hub to compress covering among the embodiment.(this axle sleeve is fixed on anchor clamps center support 3 places at the anchor clamps centre of sphere place axle sleeve 13 to be set, on the axle sleeve Connection Block 18 on interior shape clamp 1 termination, this axle sleeve Connection Block should be avoided interfering with rotating shaft fixed cover 17), be socketed with a quick-release annular wheel hub 12 outside the axle sleeve 13, be connected with many flexible holddown belts 5 on the wheel hub outer shroud, this holddown belt and interior shape clamp 1 equidirectional being fixed on the hook 6 of holding frame annular slab 2 outsides.
Referring to Fig. 2, quick-release wheel hub 12 among the embodiment, bore three apertures of system in the suitable position of wheel hub, this hole near the axle aperture, position undersized in the diameter of steel ball, steel ball 14, spring 15 and housing screw 16 are installed in the hole, while open semicircle groove in appropriate location on axle sleeve 13, size is identical with the steel ball radius.When wheel hub was installed, when steel ball 14 moves to notch position vertically, under the effect of spring force, steel ball can be stuck in the notch place, is used to locate the radial position of wheel hub; When the product undercarriage need unload lower hub, steel ball was subjected to axial force extrusion spring 15, and steel ball returns to the position that equals the wheel hub internal diameter, and wheel hub just can in axial direction shift out.
The application's sphere is confined position fixture and is adopted interior shape clamp to support the location covering, scribe bands realizes the line location of whole external radiation bars around the rotation of the sphere frame centre of sphere, quick-release wheel hub and flexible holddown belt compress covering and substitute traditional profile clamp, increased the opening character in the riveted joint process, make things convenient for the product undercarriage, reduce labour intensity, improved productivity ratio, can be widely used in the location of similar aircraft sphere mount structure.
