The specific structure of the patch application positioning structure of the embodiment of the present invention is described below with reference to fig. 1 to 2.
As shown in fig. 1-2, fig. 1 discloses a patch laying and positioning structure, which comprises a light-transmitting body 1, horizontal graduation marks 2, preset graduation marks 3, error graduation marks 5 and a positioning part 6. The horizontal graduation mark 2 is arranged on the light-transmitting body 1. The preset scale marks 3 are arranged on the light-transmitting body 1, the preset scale marks 3 are multiple, the multiple preset scale marks 3 are intersected with the horizontal scale marks 2 at the positioning points 4, the included angles between the preset scale marks 3 and the horizontal scale marks 2 are preset included angles, and the multiple preset included angles are different. Both sides of the horizontal graduation mark 2 and the plurality of preset graduation marks 3 are respectively provided with an error graduation mark 5, the error graduation mark 5 penetrates through the positioning point 4, and an included angle between the error graduation mark 5 and the preset graduation marks 3 and the horizontal graduation mark 2 is an error angle. The positioning parts 6 are used for positioning the patch 8, the positioning parts 6 are multiple, the positioning parts 6 are arranged at intervals in the radial direction of the transparent body 1, and when the projection of the outer peripheral surface of the patch 8 on the transparent body 1 is positioned on one positioning part 6, the centroid of the patch 8 coincides with the positioning point 4. Wherein a part of the patch 8 is located outside the light transmissive body 1 when the centroid of the patch 8 coincides with the anchor point 4.
It can be appreciated that, because the horizontal scale mark 2, the preset scale mark 3, the error scale mark 5 and the positioning part 6 are all arranged on the transparent body 1, the transparent body 1 has better light transmittance, and the patch paving positioning structure can accurately observe the position of the positioning point 4 on the paving region 9 through the transparent body 1 when being installed on the paving region 9, thereby being beneficial to accurately installing the patch paving positioning structure on the paving region 9. The horizontal scale mark 2 can be used as a reference scale mark of a plurality of preset scale marks 3, and can be aligned with a coordinate system on the paving area 9, so that when the patch 8 is placed on the transparent body 1, the angle of the fiber direction of the patch 8 on the coordinate system of the paving area 9 can be rapidly determined according to the relation between the fiber direction of the patch 8 and the preset scale marks 3, thereby being beneficial to accurately positioning the actual paving angle of the patch 8 when an operator is paving the patch 8, and ensuring that the actual paving angle of the patch 8 is close to the preset paving angle of the patch 8 to the greatest extent. When the patch 8 is arranged on the light-transmitting body 1 through the arrangement of the error scale marks 5, the actual pavement angle of the patch 8 is positioned in the error range of the preset scale marks 3, namely in the error range of the preset pavement angle, so that the error between the actual pavement angle of the patch 8 and the preset pavement angle can be accurately judged, and the position of the patch 8 can be conveniently adjusted by an operator, so that the error between the actual pavement angle of the patch 8 and the preset pavement angle of the patch 8 when the patch 8 is on the paving area 9 is reduced to the maximum extent. Because the patch laying positioning structure is installed on the laying area 9, the position relationship between the horizontal scale mark 2 and the coordinate system on the preset scale mark 3 and the coordinate system on the laying area 9 can be adjusted to enable the origin of the coordinate system of the positioning point 4 and the coordinate system of the laying area 9 to be consistent, and meanwhile, the positioning part 6 can ensure that the centroid of the patch 8 is consistent with the positioning point 4 when the patch 8 is arranged on the transparent body 1, so that the centroid of the patch 8 is consistent with the origin of the laying area 9 by adjusting the position relationship between the peripheral surface of the patch 8 and the positioning part 6, and the patch 8 can be ensured to be positioned on the accurate laying position on the laying area 9 by the position of the patch 8 on the transparent body 1. In addition, because when the patch 8 is located at the accurate paving position, a part of the patch 8 is located at the outer side of the transparent body 1, so that an operator can fix the patch 8 on the paving region 9 through the patch 8 at the outer side of the transparent body 1, at this time, relative displacement is difficult to occur between the patch 8 and the paving region 9, the operator can withdraw the transparent body 1 again so as to reuse the patch paving positioning structure, and the patch 8 originally located on the transparent body 1 can be fixed on the paving region 9 after the transparent body 1 is withdrawn, namely, accurate installation of the patch 8 on the paving region 9 is completed.
According to the patch laying positioning structure of the embodiment, since the angle of the fiber direction of the patch 8 on the laying area 9 and the error between the preset ply angle of the patch 8 can be ensured to be within the acceptable range by the horizontal graduation mark 2, the preset graduation mark 3 and the error graduation mark 5, the centroid of the patch 8 can be positioned on the origin of the coordinate system of the laying area 9 by the positioning part 6, so that the patch 8 can accurately patch the laying area 9, and the light-transmitting body 1 can be drawn out from between the patch 8 and the laying area 9 after the patch 8 is positioned and fixed on the laying area 9, so that the light-transmitting body 1 can be reused for a plurality of times. Therefore, the patch paving positioning structure of the embodiment can play a role in quickly and reliably measuring and positioning the angle and the position of the patch 8, is simple and convenient to operate, has a good turnover utilization rate, can effectively improve the gluing repair effect of the patch 8 on the paving area 9, and improves the paving efficiency and the paving accuracy of the patch 8.
In some alternative embodiments, the light-transmitting body 1 is made of a transparent or translucent plastic material. Of course, in other embodiments of the present invention, the light-transmitting body 1 can also be made of other light-transmitting materials, without being limited thereto.
In some embodiments, the patch placement positioning structure further includes a plurality of radial graduation lines (not shown), wherein the vertices of the plurality of radial graduation lines are located on the positioning point 4, and an included angle between two adjacent radial graduation lines is not greater than an error angle.
It should be noted that, the ply angle of the patch 8 will only select a part of fixed values in the actual use process, so that a plurality of preset included angles can be set to conventional ply angles, which is convenient for operators to observe and use the patch paving positioning structure, and improves the paving efficiency of the patch 8. It will be appreciated that in some situations of use, there is a possibility of choosing an irregular ply angle in the fibre direction of the patch 8 on the coordinate system of the ply area 9, and the plurality of radial graduation lines of this embodiment can facilitate the operator to locate the ply angle of the patch 8 when the ply angle is set to an irregular value, and the plurality of radial graduation lines are all located below the horizontal graduation line 2 to prevent the radial graduation lines from interfering with the use of the preset graduation line 3 set to the regular ply angle. The angle between two adjacent radial graduation marks is not larger than the error angle, so that an operator can conveniently determine the error between the actual laying angle and the preset laying angle of the patch 8 when positioning the fiber direction of the patch 8, and the error graduation mark 5 positioned above the horizontal graduation mark 2 is not required to be additionally arranged. According to the patch laying and positioning structure, due to the fact that the patch laying and positioning structure is provided with the plurality of radiation scale marks, the application range of the patch laying and positioning structure in the actual use process can be improved.
In some embodiments, as shown in fig. 1 and 2, the value of the preset included angle is an acute angle between the preset tick mark 3 and the horizontal tick mark 2, the preset included angle of the preset tick mark 3 located on the path rotating in the counterclockwise direction from the horizontal tick mark 2 is a positive number, and the preset included angle of the preset tick mark 3 located on the path rotating in the clockwise direction from the horizontal tick mark 2 is a negative number.
In the composite material, the included angle between the longitudinal or warp fibers in the ply and the X axis of the reference coordinate system is the ply angle, and the ply angle is measured from the X axis of the reference coordinate system and is positive in the anticlockwise direction. It can be understood that, in the embodiment of the present invention, the reference coordinate system is the coordinate system on the laying area 9, because the horizontal graduation line 2 is generally aligned with the X axis of the coordinate system on the laying area 9 during the actual installation process of the transparent body 1, and other preset graduation lines 3 are aligned with other axes on the coordinate system of the laying area 9 to achieve the superposition of the locating point 4 and the origin of the coordinate system of the laying area 9, the numerical value of the preset graduation line 3 on the transparent body 1 is defined according to the definition of the laying angle, so that it is convenient for an operator to install the transparent body 1 on the laying area 9, and quickly read the included angle of the fiber direction of the patch 8 after installing the patch 8 on the transparent body 1, thereby determining the actual laying angle of the patch 8, being beneficial for the operator to quickly compare the actual laying angle with the preset laying angle, and determining the error of the actual laying angle, and improving the laying and adjusting efficiency of the patch 8, thereby improving the laying efficiency of the patch 8 on the laying area 9.
In some embodiments, as shown in fig. 1 and 2, the preset included angle comprises 30 °, 45 °, 60 °, 75 °, 90 °, 75 °, 60 °, 45 °, or 30 °.
It can be appreciated that, since the conventional laying angle in the actual laying process of the patch 8 includes the angle, the preset scale line 3 of the preset included angle is set on the transparent body 1, so that the processing efficiency of the patch laying positioning structure can be improved, the excessive preset scale line 3 can be avoided, the reading efficiency of operators is improved, and the laying efficiency of the patch 8 on the laying area 9 is improved. Of course, in other embodiments of the present invention, the preset included angle can also be determined according to actual requirements, without specific limitation.
In some embodiments, as shown in fig. 1 and 2, the positioning portion 6 includes a plurality of positioning lines 61, and a plurality of positioning lines 61 are disposed on each of the horizontal graduation line 2 and the preset graduation line 3, and a distance between two adjacent positioning lines 61 is not greater than 1mm.
It can be understood that by arranging a plurality of positioning lines 61 on the horizontal graduation line 2 and the preset graduation line 3, the distances between a plurality of different points on the outer circumferential surface of the patch 8 and the centroid of the patch 8 can be measured in advance, and when the patch 8 is mounted on the transparent body 1, the distances between the plurality of different points on the outer circumferential surface of the patch 8 on the horizontal graduation line 2 or the preset graduation line 3 are the measured distances, so that the coincidence of the centroid of the patch 8 with the origin of the coordinates of the positioning point 4 and the paving region 9 can be realized, and the reliability of the positions of the patch 8 on the transparent body 1 and the paving region 9 can be ensured. In this embodiment, the cross-sectional shape of the patch 8 may be an axisymmetric shape or an irregular shape, and accurate installation of patches 8 with different shapes may be ensured by a measurement and comparison method, so as to improve the application range of the patch laying and positioning structure.
In some specific embodiments, as shown in fig. 1 and 2, patch 8 is circular in cross-section, and positioning portion 6 further includes a plurality of circular lines 62 having different radii. It will be appreciated that in the actual laying process of the actual patch 8, the patch 8 is generally configured to be axisymmetric, especially in a plurality of circles, so that the positioning portion 6 further includes a plurality of circular lines 62 with different radii, which not only facilitates quick installation of the patch 8 on the transparent body 1, but also facilitates adjustment of the fiber direction of the patch 8 after the patch 8 is installed on the transparent body 1, so that the actual laying angle of the patch 8 is located within the error range of the preset laying angle, and meanwhile, because the patch 8 is circular, the circle center of the patch 8 can be ensured to be located on the positioning point 4 in the process of adjusting the fiber direction, thereby improving the positioning and installation efficiency of the patch 8.
In some specific embodiments, the spacing between two adjacent positioning lines 61 is 1mm, which can facilitate the observation and measurement by the operator.
In some embodiments, as shown in fig. 1 and 2, the patch laying positioning structure further comprises a fixing hole 7, wherein the fixing hole 7 is arranged on the light-transmitting body 1, and the fixing hole 7 is arranged at a distance from the positioning point 4.
It can be appreciated that when the centroid of the patch 8 and the positioning point 4 are overlapped, the setting of the fixing hole 7 can conveniently realize that a part of the patch 8 is positioned on the outer side of the transparent body 1, and a part of the patch 8 is positioned on the fixing hole 7, namely, a part of the patch 8 is positioned on the outer side of the transparent body 1, so that the installation efficiency of the patch 8 and the extraction efficiency of the transparent body 1 are improved, and the use experience of operators is improved. Meanwhile, the fixing holes 7 and the locating points 4 are arranged at intervals, so that the fixing holes 7 can not influence the installation and locating effects of the locating points 4 on the patch 8 and the light-transmitting body 1.
In some embodiments, as shown in fig. 1, the fixing hole 7 is a sector, the vertex of the sector is located on the positioning point 4, and the sector is located below the horizontal graduation mark 2.
It will be appreciated that the fixing hole 7 is configured in a fan shape, so that the size of the fixing hole 7 can be greatly increased on the premise of reducing the influence on the preset scale mark 3, and the fixing effect of the patch 8 on the paving region 9 before the light-transmitting body 1 is drawn out can be improved.
Of course, in other embodiments of the present invention, the fixing hole 7 may be disposed on the periphery of the light-transmitting body 1, and the specific disposition position of the fixing hole 7 may be determined according to the actual requirement, which is not limited herein.
In some embodiments, as shown in fig. 1, the angle between the radius of the sector and the horizontal graduation line 2 adjacent thereto is not less than 45 °.
It can be appreciated that through the above-mentioned structure setting, can ensure that preset scale mark 3 that preset angle is 45 and-45 can not be influenced by fixed orifices 7 to use experience when improving operating personnel and using the patch to lay and paste location structure.
In some embodiments, the light-transmissive body 1 is a flexible member.
It can be appreciated that the above-mentioned structure arrangement can ensure that the light-transmitting body 1 can be mounted on the paving region 9 with a large curvature, so as to improve the application range of the patch paving positioning structure, and enable the patch paving positioning structure to have an accurate and reliable positioning effect on the position of the patch 8 in the paving region 9 with a high curvature. For example, when the laying area 9 is located at the front edge of the tail with a large curvature, that is, the patch 8 needs to be positioned for the light-transmitting body 1 of the flexible member, the application of the light-transmitting body 1 of the flexible member is not limited to the front edge of the tail.
In some embodiments, the error angle is 2 ° -6 °.
It will be appreciated that the error angle is set to 2 ° -6 ° not only facilitates the adjustment by the operator, but also enables the patch 8 to have a better laydown effect on the laydown area 9 when there is an error between the actual laydown angle and the preset laydown angle of the patch 8.
In some specific embodiments, the error angle is 3 ° or 5 °. It will be appreciated that in the prior art studies it has been shown that an error in the lay-up angle of the patch 8 of greater than 3 ° or 5 ° has a greater effect on the repair of the patch 8 on the lay-up area 9, and therefore setting the error angle to 3 ° or 5 ° can be adapted to a variety of use situations, thereby improving the versatility of the patch lay-up positioning structure.
