[0002] Structural parts on an aircraft bear various functions, such as mutual connection, force bearing, relative movement, etc., and some positions of some structural parts also need to have the functions of electric conduction, grounding, communication, information exchange, etc. In the related art, an aluminum alloy structural part needs to reserve an electric bonding area in the part design requirement. These areas do not require anodizing, cannot be painted, and only need to be chemically converted, i.e., the electric conduction of these areas needs to be reserved to realize the above functions. To reserve these areas from anodizing and painting, the areas need to be shielded. In the related art, the shielding work in the early stage is very tedious. The shielding adhesive film needs to be cut into a shape consistent with the shape of the part (i.e., the structural part), and the shielding adhesive film in the shielding area needs to be broken. After the adhesive film is attached to the part and compacted, the excess adhesive film is torn off to leave only the adhesive film at the electric bonding position. The whole process takes a lot of time and is prone to misalignment when the adhesive film is attached. The adhesive film at the electric bonding position may also be torn off when the adhesive film is torn off. In addition, a large amount of unrelated adhesive film is wasted.

[0036] Figure 1 A structural schematic view of the shielding tool 100 provided in the embodiments of the present application is shown in FIG. 1. Figure 2 A structural schematic view of the shielding tool 100 provided in the embodiments of the present application is shown in FIG. 1. Figure 3 A structural schematic view of the shielding tool 100 provided in the embodiments of the present application is shown in FIG. 1. Figure 4 A structural schematic view of the shielding tool 100 provided in the embodiments of the present application is shown in FIG. 1. Figure 5 A structural schematic view of the shielding tool 100 provided in the embodiments of the present application is shown in FIG. 1. Figures 1-5As shown, the shielding tool 100 can include a shielding plate and a film 11. The shielding plate has shielding holes 102 formed by the shape of the shielding plate itself; a second shielding plate 103; and mounting grooves 104; the film 11 is detachably arranged in the shielding holes 102 of the second shielding plate 103; wherein, when in the first working condition, the shielding plate and the structural part 200 are matched through the mounting grooves 104; when in the second working condition, the shielding plate and the structural part 200 are separated from each other, and the film 11 is attached to the structural part 200.

[0037] It is worth noting that the shielding tool 100 is matched with the structural part 200 through the mounting grooves 104 (i.e. the first working condition, as shown in Figure 1 ), realizing the quick mounting and dismounting between the shielding tool 100 and the structural part 200, while the film 11 can be produced by printing, with various specifications and strong adaptability, and only needs to be selected and attached to the structural part 200 (after the film 11 is attached to the structural part 200, the shielding plate and the structural part 200 are separated from each other) in use, without manual cutting or adjustment, greatly improving the work efficiency.

[0038] In this embodiment, the number of the shielding holes 102 of the second shielding plate 103 and the film 11 is multiple, and when in the first working condition, several films 11 are arranged in part of the shielding holes 102 of the second shielding plate 103. It can be understood that the part can be all of the shielding holes 102 of the second shielding plate 103, or 1, 2 or more of the shielding holes 102 of the second shielding plate 103.

[0039] It is worth noting that this structure allows the operator to selectively install the film 11 in the specific shielding hole 102 of the second shielding plate 103 according to the actual shielding requirement, without covering all of them every time, thereby improving the adaptability of the tool. For complex structural parts 200, differential shielding for different areas can be realized, flexibly coping with the process requirements of local area shielding and partial area exposure. At the same time, the film 11 can be selectively installed according to actual needs, which can avoid unnecessary material waste and further reduce costs.

[0040] Please refer to Figure 1 and Figure 2 again, the shielding plate includes a first shielding plate 101 and a second shielding plate, when in the first working condition, the first shielding plate 101 is erected on the structural part 200 along a first preset direction, and the second shielding plate is laid on the structural part 200 along a second preset direction, wherein the first preset direction and the second preset direction are perpendicular to each other.

[0041] It should be understood that the first preset direction refers to the longitudinal direction as shown in Figure 1 , and the second preset direction refers to the transverse direction as shown in Figure 1 .

[0042] It is worth mentioning that the first shielding plate 101 and the second shielding plate are arranged in a direction perpendicular to each other, which can effectively cover different surfaces of the structural member 200, and is suitable for shielding requirements in multiple angles and directions. At the same time, the two plates are laid perpendicular to each other to avoid multi-layer errors caused by the stacking of shielding plates in the same direction, thereby improving the shielding accuracy.

[0043] As shown in Figure 1 and Figure 3 , the cross section of the shielding hole 102 of the second shielding plate 103 includes a circle, an ellipse or a square.

[0044] Specifically, the circular, elliptical or square cross-sectional design can be flexibly matched according to different requirements of the surface features of the structural member 200 and the shape of the shielding area, thereby ensuring the pertinence and accuracy of the shielding effect. It can be applied to working conditions where the surface of the structural member 200 has various geometric shapes, such as round holes, long holes or rectangular areas, thereby improving the applicability of the shielding tool 100.

[0045] Optionally, the shielding plate is an acrylic shielding plate.

[0046] Specifically, the acrylic shielding plate has the advantages of high transparency and strong visibility. It closely fits the part and can leave a high-visibility electrically connected area to be shielded, thereby facilitating the application of the adhesive film 11 and improving the efficiency of the shielding operation.

[0047] In the embodiment, the shielding hole 102 of the second shielding plate 103 and the mounting groove 104 are located on two opposite surfaces of the shielding plate and are independent of each other.

[0048] It is worth mentioning that the shielding hole 102 of the second shielding plate 103 and the mounting groove 104 are arranged on different surfaces, which clearly defines the functional division of the two, prevents interference caused by overlapping or cross design, and improves the use efficiency of the tool. The shielding hole 102 of the second shielding plate 103 focuses on the function of applying the adhesive film 11, while the mounting groove 104 focuses on the fixing function, thereby avoiding the influence of shielding effect or stability due to mixed functions.

[0049] As shown in Figure 5 , the profile of the mounting groove 104 is similar to the profile of the structural member 200, and when in the first working condition, the mounting groove 104 and the structural member 200 have a profiling gap 105 therebetween.

[0050] It is worth mentioning that the installation groove 104 is similar in profile to the structural member 200, so that the shielding plate can better fit the surface of the structural member 200, avoiding the problem of excessive gap or poor fit caused by profile mismatch. At the same time, the profiling gap 105 can reserve a certain space for the assembly of the shielding plate, making the installation operation more smooth, especially in the scene that needs to be installed and disassembled multiple times, improving the work efficiency.

[0051] Optionally, the profiling gap 105 is 0.5mm.

[0052] Specifically, the profiling gap 105 of 0.5mm can improve the installation operability while ensuring the stability of the installed structure when applied to the structural member 200 in the field of aerospace. Depending on the specific implementation environment, 0.3mm, 0.7mm, etc. can also be used. The present embodiment does not constitute a limitation on the profiling gap 105, but only illustrates the preferred way.

[0053] In the present embodiment, the thickness of the shielding plate is 4mm. It can be understood that depending on the specific implementation environment, a shielding plate with a thickness of 3mm or 5mm can also be selected according to the size of the structural member 200.

[0054] The present application also provides a paint spraying assembly comprising the shielding tool 100100 described above and having all the beneficial effects thereof.

[0055] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application is included in the protection scope of the present application.
