Turn to a point, termination locating piece is reduced to a point, first analyzes the movement locus in x/y plane, using CATIA softwares into
Row kinematics simulation analysis, tracks the track (being reduced to a little) of the locator end locating piece in simulation process, while records its end
The position coordinates that endpoint reaches, some point (x, y) is represented with following polar equation in x/y plane：
Wherein ρ ∈ (0,350) (unit：Mm), θ ∈ (- 35 °, 35 °).Point on x/y plane rotates and shape for 360 ° further around y-axis
Into path be exactly the working space of flexible retainer of connecting, such as Fig. 7, after having gathered data, draws series connection flexible retainer work
Make the 3-D graphic in space, consider 2 width of of U-shaped rotating mechanism itself, it can be seen that the working space for flexible retainer of connecting
Similar to the entity space of an annulus row.
Series connection flexible retainer is connected on frock frame by boxlike connection mode, is fastened by bolts.Boxlike connects
Joint form do not have too big deformation compared to traditional welding structure, and can be in the side such as friction coefficient, steel pipe thickness
Face is improved, and can reach good effect.The connector of boxlike connection is from the aspects of designing, manufacturing and installing and using, much
Better than welding structure.This design is so that series connection flexible retainer dismounting is very convenient, it is only necessary to unscrews bolt, then series connection is flexible
Locator is freely slidable on crossbeam.It is required that there is one layer of varnish to shield on frock cruciform bracing surface so that series connection
Flexible retainer is slided more smooth.
Operator uses optics gaze point manual adjustment termination locating piece, by connecting the detection unit of laser tracker,
Accurately positioned with the help of supporting measuring system, measuring system can real-time display locator termination locating piece position
Appearance, each joint adjust the alignment system for building frock qualification in place.Locating piece is adjusted to after theoretical position, successively locks institute
There is movable joint, realization is accurately positioned.When Product Assembly completes out frame, all locking devices only need to be loosened, locator is remote
From product, product can go out frame.The operating procedure of whole frock simplifies, and operation is convenient, substantially increases aircraft manufacturing
Efficiency.
The utility model overall structure uses modularized design, it, which forms submodule, has replaceability, and difference series connection is soft
Submodule between property locator also has interchangeability.Its novelty simple in structure, is assembled suitable for different model aircraft components,
Different submodules can be configured according to positioning requirements and assembly technology feature, can quick regulation, improve work efficiency, improve work
Assembly precision is filled, openr operating space is provided for frock.Also, the manufacturing cycle is short, cost is low, flexible strong.
The technology contents and technical characterstic of specific embodiment of the utility model are had revealed that above, it being understood, however, that
Under the creative ideas of the utility model, those skilled in the art can clearly not show herein to various features disclosed above and
The combination of the feature gone out makes various changes and improves, but belongs to the scope of protection of the utility model.
