The specific structure of the patch placement 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 placement and positioning structure, which includes a light-transmitting body 1, horizontal scale lines 2, preset scale lines 3, error scale lines 5 and a positioning portion 6. The horizontal scale marks 2 are arranged on the light-transmitting body 1. Preset scale mark 3 and establish on printing opacity body 1, preset scale mark 3 and be a plurality of, a plurality of scale mark 3 of presetting intersect in setpoint 4 with horizontal scale mark 2, and the contained angle of presetting between scale mark 3 and the horizontal scale mark 2 is for presetting the contained angle, a plurality of contained angles diverse that preset. Horizontal scale mark 2 and the both sides of a plurality of scale mark 3 of presetting all are equipped with an error scale mark 5, and error scale mark 5 passes setpoint 4, and the contained angle between error scale mark 5 and the preset scale mark 3 and the horizontal scale mark 2 is the error angle. The positioning parts 6 are used for positioning the patch 8, the plurality of positioning parts 6 are arranged at intervals in the radial direction of the light-transmitting body 1, and when the projection of the outer peripheral surface of the patch 8 on the light-transmitting body 1 is positioned on one positioning part 6, the centroid of the patch 8 coincides with the positioning point 4. When the centroid of the patch 8 is coincident with the positioning point 4, a part of the patch 8 is located outside the light-transmitting body 1.

It can be understood that, because horizontal scale mark 2, preset scale mark 3, error scale mark 5 and location portion 6 all set up on printing opacity body 1, printing opacity body 1 has better light transmissivity, can see through printing opacity body 1 accurately and observe the position of setpoint 4 on paving region 9 when making patch paving location structure install in paving region 9 to be favorable to paving the patch and pasting location structure accurately and install on paving region 9. Horizontal scale mark 2 can regard as a plurality of reference scale marks of predetermineeing scale mark 3 to use, simultaneously can align with the coordinate system of paving on the region 9, when placing patch 8 on printing opacity body 1 like this, can confirm the angle of the fibre direction of patch 8 on the coordinate system of paving region 9 fast according to the fibre direction on the patch 8 and the relation of predetermineeing between the scale mark 3, thereby be favorable to operating personnel to spread the layer angle to patch 8 when paving patch 8 and carry out accurate location, can guarantee under the at utmost that patch 8's actual layer angle of spreading is close with patch 8's the layer angle of spreading in advance. When error scale mark 5 set up and can make patch 8 set up on printing opacity body 1, make patch 8 actually spread the layer angle and be located the error range of preset scale mark 3, be located the error range of spreading the layer angle in advance promptly, can accurately judge patch 8 actually spread the layer angle and predetermine the error of spreading between the layer angle, also can be convenient for operating personnel to carry out position adjustment to patch 8, reduce patch 8 when spreading on regional 9 the error between the layer angle is spread in advance of patch 8 actually and patch 8. Because the patch is spread and is pasted the location structure and install on spreading and pasting the region 9, can be through adjusting horizontal scale mark 2 and predetermine the position relation between scale mark 3 and the coordinate system on spreading and pasting the region 9, so that the original point of the coordinate system of setpoint 4 and spreading region 9 is unanimous, location portion 6 can ensure that the centroid of patch 8 is unanimous with setpoint 4 when patch 8 sets up on printing opacity body 1 simultaneously, thereby can be through the position relation of the outer peripheral face of adjustment patch 8 and location portion 6, so that the centroid of patch 8 is unanimous with the original point of spreading and pasting region 9, can ensure through the position of patch 8 on printing opacity body 1 that patch 8 lies in accurate shop and pastes the position on spreading and pasting region 9 promptly. In addition, because patch 8 is located when accurate shop pastes the position, a part of patch 8 is located the outside of printing opacity body 1, make operating personnel be fixed in patch 8 on shop pastes region 9 through patch 8 in the outside of printing opacity body 1, be difficult to appear relative displacement between patch 8 and the shop pastes region 9 this moment, operating personnel can take printing opacity body 1 out again, spread the location structure with reuse patch, and patch 8 that originally is located on printing opacity body 1 then can be fixed in shop after printing opacity body 1 takes out on the region 9, the accurate installation of patch 8 on shop pastes region 9 has been accomplished promptly.

According to patch paving location structure of this embodiment, because can be through horizontal scale mark 2, predetermine scale mark 3 and error scale mark 5 and ensure that the angle of the fibre direction of patch 8 on paving area 9 and the error between the preset angle of paving of patch 8 are in acceptable within range, can be so that the centroid of patch 8 is located the initial point of the coordinate system of paving area 9 through location portion 6, thereby ensure that patch 8 can be accurate to paving area 9 subsidy, printing opacity body 1 can be fixed in and is taken out from between patch 8 and the paving area 9 after on paving area 9 at patch 8 location completion, make printing opacity body 1 can reuse many times.

In some alternative embodiments, the light-transmissive 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 be made of other materials having light-transmitting property, and need not be limited specifically.

In some embodiments, the patch placement positioning structure further includes a plurality of radial graduation lines (not shown), the vertexes of the radial graduation lines are all located on the positioning point 4, and the included angle between two adjacent radial graduation lines is not greater than the error angle.

It should be noted that, the ply angle of the patch 8 usually only selects a part of fixed numerical values in the actual use process, so that a plurality of preset included angles can be set as conventional ply angles, the patch laying and positioning structure can be conveniently observed and used by an operator, and the laying efficiency of the patch 8 is improved. It will be appreciated that in some applications, the angle of the fibre direction of the patch 8 in the coordinate system of the placement area 9 may be an irregular ply angle, and the plurality of radial scale marks of this embodiment may facilitate the operator to locate the placement angle of the patch 8 when the ply angle is set to an irregular value, and the plurality of radial scale marks may be located below the horizontal scale mark 2 to prevent the radial scale marks from interfering with the use of the preset scale marks 3 set to a regular ply angle. The included angle between two adjacent radial scale lines is not larger than the error angle, so that an operator can conveniently determine the error between the actual ply angle and the preset ply angle of the patch 8 when positioning the fiber direction of the patch 8, and the error scale line 5 positioned above the horizontal scale line 2 does not need to be additionally arranged. According to the patch paving and positioning structure of the embodiment, due to the fact that the patch paving and positioning structure is provided with the plurality of radioactive scale lines, the application range of the patch paving and positioning structure in the actual use process can be improved.

In some embodiments, as shown in fig. 1 and 2, the preset included angle has an acute angle between the preset scale line 3 and the horizontal scale line 2, the preset included angle of the preset scale line 3 on the path rotating from the horizontal scale line 2 in the counterclockwise direction is a positive number, and the preset included angle of the preset scale line 3 on the path rotating from the horizontal scale line 2 in the clockwise direction 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 counterclockwise direction. It can be understood that, in the embodiment of the present invention, the reference coordinate system is the coordinate system on the placement area 9, and since the horizontal scale lines 2 are generally aligned with the X-axis of the coordinate system on the placement area 9 in the actual installation process of the light-transmitting body 1, and the other preset scale lines 3 are aligned with the other axes on the coordinate system of the placement area 9 to achieve the coincidence of the original points of the positioning point 4 and the placement area 9, the numerical values of the preset scale lines 3 on the light-transmitting body 1 are defined according to the definition of the placement angle, which can facilitate the operator to install the light-transmitting body 1 on the placement area 9, and quickly read the included angle of the fiber direction of the patch 8 after the patch 8 is installed on the light-transmitting body 1, so as to determine the actual placement angle of the patch 8, which is beneficial for the operator to quickly compare the actual placement angle with the preset placement angle, and the error of the actual ply angle is determined, so that the laying and adjusting efficiency of the patch 8 can be improved, and the laying efficiency of the patch 8 on the laying area 9 is improved.

In some embodiments, as shown in fig. 1 and 2, the predetermined included angle comprises 30 °, 45 °, 60 °, 75 °, 90 °, -75 °, -60 °, -45 °, or-30 °.

It can be understood that, because the conventional angle of spreading of 8 actual shop of patches in-process includes above-mentioned angle, consequently set up the preset scale mark 3 of the above-mentioned contained angle of predetermineeing on printing opacity body 1, can improve the patch and spread the machining efficiency who pastes location structure, can also avoid predetermineeing scale mark 3 too much to improve operating personnel's reading efficiency, and then improve the patch 8 and spread the efficiency of pasting on spreading the regional 9. Of course, in other embodiments of the present invention, the preset included angle can also be determined according to actual requirements, and does not need to be specifically limited.

In some embodiments, as shown in fig. 1 and 2, the positioning portion 6 includes a plurality of positioning lines 61, a plurality of positioning lines 61 are disposed on each of the horizontal scale lines 2 and the preset scale lines 3, and a distance between two adjacent positioning lines 61 is not greater than 1 mm.

It can be understood that, by setting a plurality of positioning lines 61 on the horizontal scale line 2 and the preset scale line 3, the distance between the centroid of the patch 8 and a plurality of different points on the outer peripheral surface of the patch 8 can be measured in advance, and when the patch 8 is installed on the light-transmitting body 1, the distance between the centroid of the patch 8 and the horizontal scale line 2 or the preset scale line 3 is the measurement distance, so that the coincidence of the centroid of the patch 8 and the origin of coordinates of the positioning point 4 and the placement area 9 can be realized, and the reliability of the position of the patch 8 on the light-transmitting body 1 and the placement area 9 can be ensured. It should be noted that, in this embodiment, the cross-sectional shape of the patch 8 may be an axisymmetric shape or an irregular shape, and the patch 8 having different shapes can be accurately mounted by measurement and comparison, so as to improve the application range of the patch placement and positioning structure.

In some specific embodiments, as shown in fig. 1 and 2, the patch 8 is circular in cross-section, and the positioning portion 6 further includes a plurality of circular lines 62 having different radii. It can be understood that, in the actual paving process of the actual patch 8, the patch 8 is usually set to be axisymmetric, and particularly, it is most circular, so the positioning portion 6 further includes a plurality of circular ring lines 62 with different radiuses, which can not only facilitate the rapid installation of the patch 8 on the light-transmitting body 1, but also facilitate the adjustment of the fiber direction of the patch 8 after the patch 8 is installed on the light-transmitting body 1, so that the actual ply angle of the patch 8 is located in the error range of the preset ply angle, and meanwhile, because the patch 8 is circular, the patch 8 can also ensure that the circle center is located on the positioning point 4 in the process of adjusting the fiber direction, thereby the positioning and installation efficiency of the patch 8 is improved.

In some specific embodiments, the distance between two adjacent positioning lines 61 is 1mm, which can facilitate observation and measurement by an operator.

In some embodiments, as shown in fig. 1 and fig. 2, the patch placement positioning structure further includes a fixing hole 7, the fixing hole 7 is disposed on the light-transmitting body 1, and the fixing hole 7 is spaced from the positioning point 4.

It can be understood that, when the centroid of the patch 8 and the positioning point 4 coincide, which can be conveniently realized by the fixing hole 7, a part of the patch 8 is located outside the light-transmitting body 1, and a part of the patch 8 is located outside the light-transmitting body 1 when the patch 8 is located on the fixing hole 7, so that the installation efficiency of the patch 8 and the extraction efficiency of the light-transmitting body 1 are improved, and the use experience of an operator is facilitated. Meanwhile, the fixing hole 7 and the positioning point 4 are arranged at intervals, so that the fixing hole 7 can not influence the installation and positioning effects of the positioning point 4 on the patch 8 and the light-transmitting body 1.

In some embodiments, as shown in fig. 1, the fixing hole 7 has a fan shape, the vertex of the fan shape is located on the positioning point 4, and the fan shape is located below the horizontal scale line 2.

It can be understood that the fixing holes 7 are arranged in a fan shape, so that the size of the fixing holes 7 can be greatly improved on the premise of reducing the influence on the preset scale marks 3, and the fixing effect of the patch 8 on the paving area 9 before the light-transmitting body 1 is drawn out can be improved.

Of course, in other embodiments of the present invention, the fixing holes 7 can also be disposed on the periphery of the light-transmitting body 1, and the specific location of the fixing holes 7 can be determined according to actual requirements, and need not be specifically limited herein.

In some embodiments, as shown in figure 1, the angle between the radius of the sector and the horizontal scale line 2 adjacent thereto is not less than 45 °.

It can be understood that through the above structure setting, can ensure that the preset angle is 45 and-45 predetermine scale mark 3 can not influenced by fixed orifices 7 to improve operating personnel and use experience when using the patch to spread and paste location structure.

In some embodiments, the light transmissive body 1 is a flexible member.

It can be understood that, through the above-mentioned structure setting, can ensure that printing opacity body 1 can install on the region 9 of paving that has great camber to improve the application scope of patch shop and paste location structure, make this patch shop paste location structure also can play accurate reliable location effect to the position of patch 8 in the region 9 of paving that has higher camber. Illustratively, when the attachment region 9 is located at the tail leading edge with a large curvature, the patch 8 needs to be positioned for the light-transmitting body 1 of the flexible member, and the application of the light-transmitting body 1 of the flexible member is not limited to the tail leading edge.

In some embodiments, the error angle is 2-6.

It can be understood that the error angle is set to be 2-6 degrees, so that the adjustment can be conveniently carried out by an operator, and when an error exists between the actual spreading angle and the preset spreading angle of the patch 8, the patch 8 can also have a good spreading effect on the spreading area 9.

In some specific embodiments, the error angle is 3 ° or 5 °. It will be appreciated that in prior art studies it has been shown that errors in the ply angle of the patch 8 greater than 3 ° or 5 ° have a greater effect on the repair of the patch 8 over the patch area 9, and therefore setting the error angle to 3 ° or 5 ° can be adapted to a variety of uses, thereby increasing the versatility of the patch placement location.
