Description
Technical field
The present invention relates to a kind of method for drilling of aircraft connector, and in particular to a kind of system of covering and skeleton connection structure
Hole method.
Background technique
Structural member in aircraft assembling process connects the position precision and surface quality pair of connecting hole based on being mechanically connected
The service life of aircraft and safety have important influence.There are a large amount of covering and skeleton connection structure in aircraft assembly,
In the case where not providing drill jig, covering and skeleton connection structure generally use scribing line by hand and drill, method particularly includes: it is assembling
The erect-position snap-gauge of skeleton part is set in type frame, and skeleton part is positioned according to snap-gauge position, connected；It is fixed on assembly jig
After the covering of position, the drilling of covering and skeleton is drawn lines and carried out on covering according to snap-gauge position.There are following for the method for drilling
Problem: skeleton part is invisible when 1, drawing lines, and covering and skeleton relative position are uncertain, if skeleton part has position during installation
Offset is set, then can generate hole location deviation, cause part rejection；2, it needs to increase a large amount of snap-gauges in type frame, not only increases type
Frame manufacturing cost, while reducing the opening character of type frame, poor operability；3, operator needs repeatedly opening and closing card in setting-out
Plate, working efficiency is low, large labor intensity.
In the prior art to improve scribing line precision, hole location is determined on skin part by the way of projection.Such as publication number
For CN103286767A, publication date is on 09 11st, 2013, in entitled " a kind of layout for drilling method of skin part "
State's invention granted patent, technical solution are as follows: a kind of layout for drilling method of skin part, comprising the following steps: 1) press size
By the border line of skin part and the central point in each hole along datum plane direction projection on datum plane；2) by subpoint with
1: 1 ratio is plotted on the steel plate with a thickness of 3-5mm；3) light hole is drilled out on the subpoint in each hole；In projection border line
Position drill out the light hole of equidistant arrangement；4) skin part is located on molding die, then steel plate is placed on skin part
Top；5) it is irradiated with parallel rays in the top of steel plate, it is whole to make to project the optical spot centre that the light hole on border line is formed
It falls in the outer rim of skin part；6) center of luminous point is marked on skin part with bow pen, i.e. completion dashing work.
The scribble method improves the precision and efficiency of skin part hole location scribing line, improves the production efficiency of skin part, realizes covering zero
The interchangeability of part.
Auxiliary member of the above-mentioned patent using steel plate as scribing line, needs to bore on the subpoint of skin part molding die
Hole, then projected to skin part with the saturating light of light hole to mark optical spot centre.The patent of invention has the disadvantage that head
First, there may be offsets in molding and bonding process for skeleton, after forming final scribing line hole location on skin part, covering with
Skeleton can not carry out hole location adjustment according to the physical location of skeleton when being linked and packed, this may cause skin part can not be applicable in and
It scraps；It, then can be by secondly, skin part can generate certain deviation when projecting on the steel plate, and steel plate light transmission again after piercing
Generate deviation again in the problem of borehole accuracy, the scribing line precision that the accumulation of deviation will lead to finally on skin part is not high；
Finally, steel plate can not be utilized repeatedly, when the process for also improving scribing line cost, while drilling on the steel plate also extends scribing line
Between, reduce the efficiency of hole location scribing line.
Summary of the invention
For solve covering and skeleton in the prior art be linked and packed drilling when, method for drilling there are hole location deviation, it is at high cost,
The problems such as cumbersome, the present invention provides the method for drilling of a kind of covering and skeleton connection structure, this method can realize hole location
With the accurate adjustment of frame position, the part rejection as caused by hole location deviation is avoided, it is not only at low cost, also improve closing
The drilling efficiency in area.
The purpose of the present invention is what is be achieved through the following technical solutions:
1, the method for drilling of a kind of covering and skeleton connection structure, which comprises the steps of:
1) it glass cloth sample making: according to the true form and size of covering, is made and covering size and shape using glass cloth
Identical glass cloth template；

6) covering, the positioning of glass cloth template: glass cloth template being removed, positions covering on assembly jig, then by glass cloth specimen
Plate is covered on covering and positions；
7) hole location adjustment setting-out: the theoretical hole location on glass cloth template is drawn lines mark on covering, and according to hole location adjustment amount,
Practical hole location adjusted is identified on covering；
8) drilling is completed.
Further, the identification method of theory hole location described in step 2 specifically: obtain and cover by CATIA V5 software
These hole location data are input to three-dimensional laser optical projection system by the three-dimensional coordinate of hole location in the theoretical shape of the digitlization of skin and covering
On, theoretical hole bitmap is projected on glass cloth template with laser-projector.
Further, the first bore dia in step 2 is less than theoretical bore dia, and first hole is only used for drawing lines on covering.
Further, the glass cloth is EW-100 glass cloth.
The technical program has the beneficial effect that:
1, template is made using glass cloth in the present invention, using the translucency of glass cloth and non-ductility, reflects skeleton part
Physical location, hole location adjustment amount is determined according to the relationship of skeleton part physical location and theoretical hole location, realizes hole location with skeleton
The accurate adjustment of position avoids the part rejection as caused by hole location deviation in skeleton and skin part assembling process, improves
Drilling efficiency.
2, glass cloth template of the present invention is low in cost and is used multiple times, and does not need to replace under normal use,
Compared to drilling on the steel plate, drilling is easier on glass cloth, more saves the time, and glass cloth can be pasted with skin-surface completely
It closes, deviation or deviation are smaller caused by will not generating due to borehole accuracy and shadow projection.
