Abstract
The invention discloses a method for measuring thickness of a paint layer of a composite material part. The method comprises the following steps of: (1) downwardly and vertically machining a V-shaped measuring hole on a dry film paint layer of a composite material carrier, wherein a circular hole at the bottom of the measuring hole is positioned on the composite material carrier; and (2) measuring a distance S between the edge of the circular hole at the bottom of the measuring hole and the edge of a circular hole on the top, and calculating the thickness D of the dry film paint layer with the following formula: D=S*F, wherein F in the formula is a coefficient value which can be tg alpha*20 and alpha is the chamfer of a drill bit. Compared with the prior art, the method accurately measures the thickness of the dry film paint layer on the composite material carrier, and the measurement method is simple and reliable.
Description
Technical field
The present invention is a kind of method of measuring thickness of paint layer of composite material part, belongs to field of measuring technique.
Background technology
At present, the dry film paint layer thickness on the metallic carrier can be measured with the method (Foucault stream) of nondestructive test, but the dry film paint layer thickness on the inapplicable mensuration composite material carrier of the method.
Dry film paint layer thickness measurement on the composite material carrier, the method that can only adopt metal testing plate to contrast is promptly put a metal testing plate on the composite material carrier side, and the metal testing plate thickness of paint layer is composite material carrier dry film paint layer thickness.Its problem is: metal testing plate dry film paint layer thickness can accurately not reflect composite material carrier dry film paint layer thickness.
The present invention designs a kind of method of measuring thickness of paint layer of composite material part that provides at above-mentioned problems of the prior art just, its objective is the dry film paint layer thickness on the accurate mensuration composite material carrier.Solving the dry film paint layer thickness directly to measure on the composite material carrier, thereby guarantee the accuracy of measurement data.
The objective of the invention is to realize by following technical measures:
Technical solution of the present invention is that a kind of V-type section that utilizes is measured dry film paint layer thickness on the composite material carrier.The step of this method is:
(1) on the dry film paint layer on the composite material carrier, process the measured hole of a V-type downward vertically, the bottom circular aperture of measured hole is located on the composite material carrier;
(2) between the edge of the edge of measuring the measured hole bottom circular aperture and top circular hole apart from S, with the thickness D of following formula calculating dry film paint layer:
D＝S×F
In the formula: F is a coefficient value, and the value of F should be tg α * 20, and α is the drill bit corner cut

Embodiment
Below with reference to drawings and Examples technical solution of the present invention is further described:
Shown in accompanying drawing 1～2, this kind measured the method for thickness of paint layer of composite material part, and it is characterized in that: the step of this method is:
(1) on the dry film paint layer on the composite material carrier 21, process the measured hole 3 of a V-type downward vertically, the bottom circular aperture 4 of measured hole 3 is located on the composite material carrier 2;
(2) between the edge of the edge of measuring measured hole 3 bottom circular aperture 4 and top circular hole 5 apart from S, with the thickness D of following formula calculating dry film paint layer (1):
D＝S×F
In the formula: F is a coefficient value, and the value of F should be tg α * 20, and α is the drill bit corner cut
That use in in-process measurement hole 3 is Paint Bohrer, and PAINT BORER is a covering device, and it comprises: the optical laying assembly constitutes; A micro drill; The illuminator of a measured zone; 5 kinds of carbon steel drill bit No.1, No.2, No.3, No.4 and No.5; The 9V charging accumulator.The selection of drill bit is that system of selection is according to the thickness of dry film paint layer 1:
During dry film paint layer 1 theoretic throat 2～200 μ m, use drill bit No.2,5.7 ° of corner cuts, coefficient value F is 2;
During dry film paint layer 1 theoretic throat 3～300 μ m, use drill bit No.5,8.5 ° of corner cuts, coefficient value F is 3;
During dry film paint layer 1 theoretic throat 5～500 μ m, use drill bit No.4,14 ° of corner cuts, coefficient value F is 5;
During dry film paint layer 1 theoretic throat 10～1000 μ m, use drill bit No.3,26.6 ° of corner cuts, coefficient value F is 10;
During dry film paint layer 1 theoretic throat 20～2000 μ m, use drill bit No.1,45 ° of corner cuts, coefficient value F is 20.
During practical operation, slip micro drill, location drilling point.Pressing the button, is that micro drill is rotated, until getting into composite material carrier 2, the slip microscope place measured hole 3 above, open illuminating lamp, see through the microscopic examination scale, determine 2 concentric circless, i.e. scale value between the edge of bottom circular aperture 4 and the top circular hole 5.Twice measurement point averaged, and guarantees result's reliability.
Compared with prior art, the inventive method has been measured the dry film paint layer thickness on the composite material carrier exactly. And measuring method is simple and reliable.
