Abstract
The utility model discloses a kind of adjustable paving frock for the U-shaped multiple material part production of aviation, the outside wall surface in type frame support works type face, regulation pulling/pushing device multiple spot between the outside wall surface and type frame of working surface to set connection.The utility model has the advantages that：1st, it is difficult to the characteristic accurately estimated with reference to the unstability and profile that multiple material forming parts have, the frock fixed compared to common working surface, type face can be adjusted for adjustable paving frock, can be adjusted according to the actual deformation of part, can effectively avoid the frock that working surface is fixed because estimate it is inaccurate and caused by scrap；2nd, the frock that common working surface is fixed is after a certain period of use time, working surface can have certain deformation, cause the part of production unqualified, need periodically to carry out profile measurement and adjustment to frock, adjustable paving frock is due to its controllability, for existing deformation, it can carry out drawing top regulation, ensure that working surface is qualified.
Description
Technical field
A kind of aviation composite production frock is the utility model is related to, it is particularly a kind of to be used for the U-shaped multiple material part of aviation
The adjustable paving frock of production.
Background technology
It is product cross section that aerospace flight vehicle, which has a kind of the characteristics of conventional U-shaped multiple material class formation part, such part,
U-shaped, part curvature is larger, and resilience or closing in are also easy to produce after having shaped, therefore, the paving frock corresponding to such part
(including multiple material class frock and thin-sheet metal class frock), need to provide certain resilience surplus or allowance for shrinkage in design,
Ensure that after part forming accurate theoretical profile can be reached.
Because multiple material class part forming mode is complex (being mostly prepreg high temperature process, make resin solidification), therefore zero
The resilience surplus or allowance for shrinkage of the frock of part (especially larger-size part) are difficult to accurately provide, and can only be estimated with experience
Margin value is counted, then the overproof phenomenon of the final part shaped occurs.The frock fixed for type face, once overproof, frock
It can only scrap and newly put, reevaluate surplus and be processed, seriously add cost and the process-cycle of product.
Utility model content
Purpose of utility model：In view of the above-mentioned problems, the purpose of this utility model, which is to provide one kind, is used for the U-shaped multiple material zero of aviation
The adjustable paving frock of part production, solves the problems, such as that the resilience surplus of frock or allowance for shrinkage are difficult to accurately estimate, and reduces
The scrappage of multiple material class part forming.
Technical scheme：A kind of adjustable paving frock for the U-shaped multiple material part production of aviation, including type frame, work type
Face, regulation pulling/pushing device, the type frame support the outside wall surface of the working surface, and the regulation pulling/pushing device is in the working surface
Multiple spot sets connection between outside wall surface and the type frame.
Further, the regulation pulling/pushing device includes base, location-plate, telescopic lever, bolt, described telescopic lever one end
Fixed with the location-plate by the bolt connection, the telescopic lever other end with the type frame, the base with it is described
The outside wall surface of working surface is fixed.By adjusting telescopic lever, make the outside wall surface bearing stress of base and working surface, to work
Make type face and produce the regulation of drawing top, its margin value is changed.
Further, the outside wall surface bearing of the base and the working surface is glued with carbon cloth and resin coats, right
Bearing is protected, and prevents stress point pressure from causing to damage to working surface greatly very much.
Further, the regulation pulling/pushing device also includes L-type location-plate, and the L-type location-plate is arranged on the flexible drawing
On one end that bar is fixed with the type frame, engage with the type frame surface.
Further, the type frame is the frame structure that welded steel forms.
Further, the lamination that the working surface is molded for the prepreg paving of the less carbon fiber class of thermal expansion factor
Plate, or be molded by invar steel.
Beneficial effect：Compared with prior art, the utility model has the advantages that：1st, have not with reference to multiple material forming parts
Stability and profile are difficult to the characteristic accurately estimated, the frock fixed compared to common working surface, can adjust paving frock energy
It is enough that type face is adjusted, it can be adjusted according to the actual deformation of part, the frock that can effectively avoid working surface from fixing
Because estimate it is inaccurate and caused by scrap；2nd, the frock that common working surface is fixed after a certain period of use time, working surface meeting
In the presence of certain deformation, cause the part of production unqualified, it is necessary to periodically carry out profile measurement and adjustment to frock, can adjust paving
Frock is pasted due to its controllability, for existing deformation, can carry out drawing top regulation, ensure that working surface is qualified.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
A kind of adjustable paving frock for the U-shaped multiple material part production of aviation, as shown in accompanying drawing 1-4,8, including type frame
1st, working surface 2, regulation pulling/pushing device 3.As shown in Figure 5, type frame 1 is to be welded with steel according to the profile of processing part
Frame structure, as shown in Figure 6, working surface 2 are molded using the prepreg paving of the less carbon fiber class of thermal expansion factor
Laminate, or made of invar steel is molded.The outside wall surface in the support works type face 2 of type frame 1, regulation pulling/pushing device 3 are working
It is provided with multiple between the outside wall surface and type frame 1 in type face 2, is attached.
As shown in Figure 7, adjusting pulling/pushing device 3 includes base 31, location-plate 32, telescopic lever 33, bolt 34, L-type positioning
Plate 35, the one end of telescopic lever 33 are connected with location-plate 32 by bolt 34, and the other end of telescopic lever 33 is fixed with type frame 1, and L-type is fixed
