AI Technical Summary

Problems solved by technology

When the error of the actual ply angle of the patch is large, it will have a great influence on the tensile strength of the patch
In the prior art, the patch laying process mainly relies on visual observation and aligns the fiber direction of the patch with the ply orientation coordinate system outside the laying area. It is difficult to measure and guarantee the laying position and angle.
In addition, when the size of the paving area is large and the size of the patch in the first few layers is small, it is particularly prone to the situation that the position and angle of the patch are out of tolerance

Embodiment 1

[0056] Refer below Figure 1-Figure 2 The patch paving positioning structure of a specific embodiment of the present invention is described.

[0057] The patch laying positioning structure of this embodiment includes a light-transmitting body 1 , a horizontal scale line 2 , a preset scale line 3 , an error scale line 5 , a positioning portion 6 and a fixing hole 7 .

[0058] The transparent body 1 is a flexible piece. The horizontal scale line 2 is provided on the transparent body 1 .

[0059] The preset scale line 3 is set on the light-transmitting body 1. There are multiple preset scale lines 3. The multiple preset scale lines 3 intersect with the horizontal scale line 2 at the positioning point 4. The preset scale line 3 and the horizontal scale line 2 The included angle between is a preset included angle, and multiple preset included angles are different from each other. The value of the preset angle is the acute angle between the preset scale line 3 and the horizontal ...

Embodiment 2

[0064] The patch paving positioning structure of a specific embodiment of the present invention is described below.

[0065] The patch paving and positioning structure of this embodiment is substantially the same as that of Embodiment 1, and only the differences between the two are described here, and the same structure as that of Embodiment 1 will not be repeated here.

[0066] The patch paving and positioning structure of this embodiment also includes a plurality of radial scale lines, and the plurality of radial scale lines are all located below the horizontal scale line 2, and the vertices of the multiple radial scale lines are all located on the positioning point 4, and the adjacent two The angle between two radial scale lines is not greater than the error angle.

[0067] A patch paving positioning method, the patch paving positioning method adopts the aforementioned patch paving positioning structure, the patch paving positioning method includes:

[0068] The first step...

Abstract

The invention discloses a patch paving and positioning structure and a patch paving and positioning method. The patch paving and positioning structure comprises a light-transmitting body, a horizontal scale line, a preset scale line, an error scale line and a positioning part. And the horizontal scale marks are arranged on the light-transmitting body. The preset scale marks are arranged on the light-transmitting body, the multiple preset scale marks and the horizontal scale mark intersect at a positioning point, the included angle between each preset scale mark and the horizontal scale mark is a preset included angle, and the multiple preset included angles are different. The two sides of the horizontal scale line and the multiple preset scale lines are each provided with an error scale line, and the error scale lines penetrate through the positioning points. The positioning parts are used for positioning the patch, and when the projection of the peripheral face of the patch on the light-transmitting body is located on one positioning part, the centroid of the patch coincides with the positioning point. When the centroid of the patch coincides with the positioning point, a part of the patch is located on the outer side of the light-transmitting body. The patch paving and positioning structure can improve the paving efficiency and paving quality of the patch.

Description

technical field [0001] The invention relates to the technical field of composite material repair, in particular to a patch laying positioning structure and a patch laying positioning method. Background technique [0002] Composite materials will have defects and damages in the process of manufacture and use, so the development and improvement of composite material repair technology is becoming increasingly important. Composite material adhesive repair is an important composite material repair method, and patching is an important process in adhesive repair. There are requirements for the fiber direction of the patch during the patch laying process. When the error of the actual ply angle of the patch is large, it will have a great influence on the tensile strength of the patch. In the prior art, the patch laying process mainly relies on visual observation and aligning the fiber direction of the patch with the layup orientation coordinate system outside the laying area, and i...
