Abstract
A kind of composite method for drilling of the present invention belongs to technique for aircraft composite manufacturing field.The technical scheme is that need to first manufacture one drives aperture size identical drilling instrument with required, the drilling instrument is made up of cutter head and knife bar.Cutter head is divided into cutting tip and fixed part, and knife bar is divided into position portion, fixed part and retained part, is positioned by knife bar position portion during drilling, and cutter head cutting tip is cut, and finally opens and makes the high hole of accurate positioning, aperture precision.The advantages of invention is drilling precision height, and perforate accurate positioning, method for drilling is simple and easy, and production efficiency is high, practical, can be promoted extensively.
Description
Technical field
A kind of composite method for drilling of the present invention belongs to technique for aircraft composite manufacturing field.
Background technology
Sandwich structure composite material is divided into two kinds of method for drilling at present, together by zero when one kind is Numerical control cutting External Shape
Perforate is made on part, and another kind need to match somebody with somebody for perforate on part in assembling with other positions runs system jointly.The hole that system of running jointly need to be matched somebody with somebody shows
There are two kinds of method for drilling, the first is the trim line for first drawing hole, is then cut with sweep-saw by line, because being cut into behaviour
Make personnel's manual operations, to be directed at the hole trim line that draws the moment in cutting is cut, due to a width of 12mm of curve saw blade,
The inadequate streamline of circular hole of system is opened, needs to repair processing to the cutting end face progress excessive mistake of streamline after cutting.Second of scene coordinates drilling
Method is that first drawing needs perforate trim line, the less drill bit of diameter is then clamped on electric drill or air drill, around the hole profile drawn
Line bores a circle aperture using interior blanking method, is finally pared off Kong Yukong excess portion misclassifications with file.Scene is needed to coordinate drilling at present
The existing two kinds of method for drilling of part, high is required to operating personnel's operational capacity, is easily damaged whole part during drilling, this two kinds
Method drilling aperture precision is relatively low, and hole centralized positioning precision is low, drilling tedious process.
The content of the invention
The purpose of the present invention：Energy is operated to operating personnel instant invention overcomes existing sandwich structure composite material hand-made hole
Power requires higher, is easily damaged whole part during drilling, and drilling tedious process, drilling aperture precision is relatively low, hole centralized positioning essence
The shortcomings that low is spent, has invented a kind of new sandwich structure composite material hand-made hole method.
Technical scheme：A kind of composite method for drilling, this method implementation steps are as follows：
(1) manufacture is with that need to drive aperture size identical drilling instrument.Drilling instrument is made up of cutter head and knife bar.Cutter head point
For cutting tip and fixed part.Wherein cutting tip is hollow cylinder, and cylindrical member at one end does not have bottom surface, and the end bottom is
Laciniation, the cylinder other end are connected with one end of fixed part.Knife bar is divided into position portion, fixed part and clamping part
Point, knife bar is multidiameter structure, has annular projection in the middle part of knife bar, and the circular protrusion is the fixed part of knife bar, knife bar one end
It is position portion between annular projection.The knife bar other end is retained part between annular projection.By screwdriver head fixing part
Divide and be coaxially connected with knife bar fixed part, and ensure knife bar position portion beyond cutter head cutting end face.
(2) according to drawing requirement, drilling position is determined.According to the manufacture of drilling position and knife bar position portion in drilling instrument
Aperture identical guide hole.
(3) knife bar position portion in drilling instrument is put into guide hole made in step 2.
(4) with the retained part of knife bar in air drill or electric drill connection drilling instrument, the rotation drilling of drilling tool insert is driven.
It is an advantage of the invention that：Simplify the drilling flow of sandwich structure composite material, at the same very it is high can sandwich answer
The drilling precision of condensation material, the inventive method drilling precision is high, and perforate accurate positioning, method for drilling is simple and easy, production efficiency
Height, it is practical.
Brief description of the drawings
Fig. 1 is drilling instrument front view
Fig. 2 is drilling instrument left view
Wherein, 1- cutter heads cutting tip, 2- screwdriver head fixing parts point, 3- knife bars position portion, 4- knife bars fixed part, 5- knives
Bar retained part.
Embodiment
The present invention will be described in detail below in conjunction with the accompanying drawings.
A kind of sandwich structure composite material method for drilling, this method implementation steps are as follows：
(1) manufacture is with that need to drive aperture size identical drilling instrument.Fig. 1 is the front view of drilling instrument, Fig. 2 is drilling
The left view of instrument, drilling instrument are made up of cutter head and knife bar.Cutter head is divided into cutting tip and fixed part.Wherein cutting tip
For hollow cylinder, cylindrical member at one end does not have bottom surface, and the end bottom is laciniation, the cylinder other end and fixed part
One end be connected.Knife bar is divided into position portion, fixed part and retained part, and knife bar is multidiameter structure, is had in the middle part of knife bar
Annular projection, the circular protrusion are the fixed part of knife bar, and knife bar one end is position portion between annular projection.Knife bar is another
One end is retained part between annular projection.Screwdriver head fixing part point is coaxially connected with knife bar fixed part, and ensures knife
Bar position portion is beyond cutter head cutting end face.
(2) according to drawing requirement, drilling position is determined.According to the manufacture of drilling position and knife bar position portion in drilling instrument
Aperture identical guide hole.
(3) knife bar position portion in drilling instrument is put into guide hole made in step 2.
(4) with the retained part of knife bar in air drill or electric drill connection drilling instrument, the rotation drilling of drilling tool insert is driven.
