Description

Technical Field

[0001] This invention relates to, but is not limited to, the field of adhesive assembly, and particularly to a positioning device and method for a honeycomb sandwich adhesive insert and a frame. Background Technology

[0002] The "panel + honeycomb sandwich" structure is currently widely used in various aircraft, such as Figure 1 As shown, in this type of structure, there is an adhesive component with an integral metal frame sealing the edge 1-1.

[0003] like Figure 2 As shown, in this type of structure, cylindrical metal parts with a central threaded hole are usually embedded in the honeycomb interlayer, collectively referred to as inserts. The central threaded hole of insert 2-1 is usually used to install airborne equipment, fix cables, etc.

[0004] like Figure 3 As shown, due to the size limitations of the airborne equipment and the requirements of the installation position, in some cases, the central threaded hole 3-1 of the insert is located within the adhesive bonding area of ​​the sealing frame. In this case, it is necessary to open a hole 3-2 at the position of the central threaded hole of the insert on the sealing frame and the honeycomb cover plate so as to expose the threaded hole of the insert.

[0005] like Figure 4 As shown, the sealing frame 4-1 is formed using a rubber bladder press and sheet metal forming mold 4-2. After forming, the sealing frame exhibits springback. To avoid the sealing frame being smaller than theoretically intended, a certain margin is reserved for the inner boundary 4-4 and outer boundary 4-3 of the sealing frame before delivery to the adhesive assembly workshop. However, this margin cannot be precisely controlled. Therefore, the sealing frame itself lacks a positioning reference. The insert mounting hole 3-2, which corresponds to the threaded hole of the insert, is also adjusted to be made before adhesive assembly.

[0006] like Figure 5 As shown, the other side panel of the adhesive component is flat and faces upwards because it is mounted on the aircraft. It is referred to as the upper panel below. There are through holes corresponding to the mounting positions of the inserts. Since it is flat, it is processed by CNC milling. Its shape and hole position accuracy can reach the accuracy level of general CNC machining. like Figure 6 As shown in the figure, since one or more airborne equipment 6-1 and 6-2 need to be installed across the symmetrical adhesive joint, in order to ensure the coordination of the assembly of each equipment and that the shape of the assembled parts meets the subsequent assembly requirements, it is necessary to ensure that the relative position of the mounting screw holes of each equipment and the relative position deviation between the screw holes and the shape of the adhesive joint meet the requirements.

[0007] like Figure 7 As shown, before the implementation of this device and method, the mounting holes 7-2 on the sealing frame 4-1 were drilled according to the mounting holes 7-1 of the honeycomb cover plate insert, which has the following disadvantages: 1. There is no positioning reference between the honeycomb cover and the sealing frame. Positioning is done manually by visual inspection, which results in unstable positioning accuracy and may lead to positioning deviation of the sealing frame, failing to meet the subsequent assembly coordination requirements. 2. Lack of drill jig during drilling results in poor roundness of the hole edge and defects such as burrs on the hole edge. Summary of the Invention

[0008] This invention provides a positioning device and method for honeycomb sandwich adhesive bonding inserts and frames, to solve the problem of unstable hole position accuracy caused by the method of "drilling holes in the sealing frame insert based on the opening of the honeycomb cover plate insert".

[0018] Secondly, this application provides a method for positioning a honeycomb sandwich adhesive insert and a frame, comprising: Step 1: Place the sealing frame 4-1 into the inner cavity of the drill mold body 10-1, and check whether the beveled surfaces around the sealing frame can be simultaneously attached to the beveled surfaces of the inner cavity of the drill mold assembly. If they are not attached, use pressure-sensitive tape 16-1 to attach it to the beveled surfaces of the inner cavity of the drill mold assembly. Step 2: Place the inner cavity pressing block 10-2 into the inner cavity of the sealing frame 4-1. Check whether the four beveled surfaces of the inner cavity pressing block 10-2 can simultaneously adhere to the beveled surfaces of the sealing frame. If they cannot adhere simultaneously, apply pressure-sensitive adhesive tape 17-1 layer by layer to the four beveled surfaces of the outer side of the inner cavity pressing block 10-2 until the inner cavity pressing block can simultaneously adhere to the four sides of the inner cavity of the sealing frame. Then, use bow-shaped clamps to clamp the inner cavity pressing block 10-2 to the sealing frame 4-1 and the drill mold body 10-1. Step 3: Use a heavy object to press the remaining flat surfaces of the sealing frame 4-1 against the drill mold body 10-1 to make them fit together. Then press the ear clamping block 10-3 against the sealing frame positioning ear, and make the outer side of the ear clamping block 10-3 coincide with the corresponding shape on the drill mold body. Clamp the ear clamping block 10-3, the sealing frame 4-1, and the drill mold body 10-1.

[0019] In summary, this patent relates to a positioning device and method for the inlay and frame of a honeycomb sandwich adhesive assembly, used in the field of adhesive assembly. Its purpose is to achieve precise positioning of multi-faceted pre-embedded inlays in honeycomb sandwich adhesive assemblies, and to ensure assembly coordination by including frame-like parts with allowance in the adhesive panel. This positioning device and method have the following advantages: The size of the inner cavity of the drill jig assembly can be adjusted by attaching pressure-sensitive adhesive tape to ensure that the sealing frame fits the inner cavity of the mold and ensures positioning accuracy. This solves the problem of no hole making and assembly positioning reference caused by the rebound of the sealing frame. The positioning components can be manufactured by improving the existing adhesive clamps, which saves space, is economical, and requires minimal changes to the original structure, without affecting the original function. By using the positioning holes on the positioning lugs, the assembly positioning accuracy of the sealing frame relative to the top panel is further improved, avoiding the amplification of the sealing frame positioning error due to minor deviations in the small hole spacing of the inserts. This ensures that the shape of the sealing frame meets the subsequent assembly requirements. The above panel was implemented using a bridging bit block. Figure 5 The positioning reference is used to position the sealing frame 4-1 and all the inserts of the part, thus satisfying the requirements for positioning of the inserts and positioning of the part's shape.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0042] This patent provides a positioning device for honeycomb sandwich adhesive inserts and frames, applicable to the precise positioning of the relative positions between inserts and the absolute positions between inserts and integral sealing frame parts with allowance delivery and no positioning reference. Ultimately, it achieves precise positioning of the relative and absolute positions of the inserts, meeting the accuracy requirements of subsequent parts assembly and airborne equipment assembly.

[0043] like Figure 8 As shown, in order to improve the assembly and positioning accuracy of the sealing frame, two process positioning lugs 8-1 are set on the oblique side of the sealing frame, and process positioning holes 8-1-A are opened on the positioning lugs.

[0044] Example 1 like Figure 9-a and Figure 9-b As shown, this application provides a positioning device for a honeycomb sandwich adhesive insert and a frame, including a drill jig assembly and a positioning assembly, wherein: Both the drill jig assembly 10 and the positioning assembly 11 include a left part and a right part, and the left part and the right part are symmetrical; The drill jig assembly 10 includes a drill jig body 10-1, an inner cavity clamping block 10-2, an ear clamping block 10-3, and a drilling bushing 10-4, which are used to position the sealing frame and drill the mounting holes for the inserts thereon. The positioning assembly 11 includes a positioning plate assembly 11-1, a positioning pressure plate assembly 11-2, a bridging positioning block assembly 11-3, a positioning pin 11-4, and a positioning screw 11-5, which are used to position the sealing frame and inserts and apply adhesive curing pressure to the adhesive assembly.

[0045] It should be noted that the following text only describes the structure and method of the left part; the right part has a symmetrical structure and the same method.

[0046] Specifically, such as Figure 10 As shown, both the left and right parts of the drill jig assembly 10 include a drill jig body 10-1, an inner cavity clamping block 10-2, an ear clamping block 10-3, and a drilling bushing 10-4. The inner cavity of the drill jig body 10-1 mates with the outer surface of the sealing frame 4-1, meaning the theoretical shape of the inner cavity of the drill jig body is consistent with the inner cavity of the sheet metal forming mold 4-2, thus ensuring that the sealing frame 4-1 can be placed inside the inner cavity of the drill jig body 10-1. The drill jig body 10-1 has a through hole corresponding to the insert mounting hole 3-2 on the sealing frame 4-1, and a drilling bushing 10-4 is installed in the through hole. The theoretical center position of the bushing hole coincides with the insert mounting hole 3-2 on the sealing frame.

[0047] Specifically, the drill jig body 10-1 is provided with positioning ears of the same shape as the process positioning ears 8-1 on the sealing frame 4-1, and corresponding through holes are provided on the positioning holes 8-1-A on the ear pieces of the sealing frame 4-1, with a drill bushing 10-4 installed in the through holes.

[0048] Specifically, the inner cavity clamping block 10-2 clamps the sealing frame during drilling, ensuring that the sealing frame and its outer surface fit snugly against the drill jig body. A 0.3mm gap is reserved between the outer shape of the inner cavity clamping block 10-2 and the inner cavity profile of the sealing frame to prevent the inner cavity of the sealing frame 4-1 from being smaller than theoretically designed due to springback, thus preventing the inner cavity clamping block 10-2 from being unable to fit into the inner cavity of the sealing frame. To allow space for the drill bit during drilling, the inner cavity clamping block 10-2 has clearance holes corresponding to the insert mounting holes 3-2 on the sealing frame 4-1, and four relief holes with an internal "+" shape.

[0049] Specifically, the ear clamping block 10-3 is used to clamp the process positioning ear left at the sealing frame, and its outer contour is consistent with the theoretical shape of the sealing frame 4-1; in order to avoid the drill bit during drilling, an opening hole is opened corresponding to the positioning hole 8-1-A on the ear of the sealing frame 4-1.

[0050] Specifically, such as Figure 11 , Figure 12 As shown, both the left and right parts of the positioning assembly include a positioning plate assembly 11-1, a positioning pressure plate assembly 11-2, a bridging positioning block assembly 11-3, a positioning pin 11-4, and a positioning screw 11-5. The positioning plate assembly 11-1 and the positioning pressure plate assembly 11-2 each have screw positioning holes for positioning the inserts and ensuring their relative positions. The bridging positioning block assembly 11-3 is equipped with a positioning bushing, which can simultaneously cooperate with both the positioning plate assembly 11-1 and the positioning pressure plate assembly 11-2 via the positioning pin 11-4 to ensure their relative positions. Furthermore, this ensures the relative positions of the inserts positioned by the positioning plate assembly 11-1 and the positioning pressure plate assembly 11-2, and controls the relationship between the sealing frame 4-1 and the upper panel. Figure 5 The deviation between the actual relative position and the theoretical relative position is used to improve assembly positioning accuracy.

[0051] Specifically, such as Figure 13 As shown, the positioning plate assembly 11-1 includes a plate base 11-1-A, a positioning bushing 11-1-B, and a positioning screw 11-1-C; as Figure 12 As shown in the sectional view AA, the template base 11-1-A has a positioning hole. The positioning hole is used to install a bushing. The bushing hole can be used to position the bridging positioning block assembly 11-3 and the ear positioning hole 8-1-A of the sealing frame 4-1. Specifically, such as Figure 14As shown, the positioning pressure plate assembly 11-2 includes a small positioning pressure plate 11-2-A, a bushing 11-2-B, a positioning screw 11-2-C, and a large positioning pressure plate 11-2-D. The small positioning pressure plate has a boss 11-2-Aa with a through hole. The bushing 11-2-B is installed inside the hole to improve the wear resistance of the positioning hole during use. The small positioning pressure plate 11-2-A and the large positioning pressure plate 11-2-D are riveted together to form a whole. The small and large positioning pressure plates are parallel to the mating surfaces of the product. The step difference δ between the two planes is set according to the thickness of the sealing frame in the diagram. After the pressure plates are riveted together to form a whole, corresponding positioning holes are set according to the theoretical positions of the inserts to ensure the relative positions of the inserts. Specifically, such as Figure 15 As shown, the bridging positioning block assembly 11-3 includes a positioning block base 11-3-A and a positioning bushing 11-3-B; as Figure 12 As shown in sectional views AA and BB, the first bushing 11-3-Ba and the second bushing 11-3-Bb can be engaged with the positioning bushing on the positioning plate assembly 11-1 and the positioning bushing 11-2-B on the positioning pressure plate assembly 11-2 respectively via the positioning pin 11-4.

[0052] Example 2 This application provides a method for positioning a honeycomb sandwich adhesive insert to a frame, which is implemented using the positioning device provided in the above embodiments. The method includes: Step 1: As Figure 16 As shown, place the sealing frame 4-1 into the inner cavity of the drill mold body 10-1. Check whether the beveled surfaces of the sealing frame and the beveled surfaces of the inner cavity of the drill mold assembly can simultaneously abut. If they do not abut, use pressure-sensitive adhesive tape 16-1 to attach it to the beveled surfaces of the inner cavity of the drill mold assembly to eliminate the gap between the beveled surfaces of the sealing frame and the beveled surfaces of the inner cavity of the drill mold assembly. Since each sealing frame has the same structure, size, and molding method, its springback is stable, and gap adjustment only needs to be performed on the first use. Step 2: As Figure 17 As shown, place the inner cavity pressing block 10-2 into the inner cavity of the sealing frame 4-1, and check whether the four bevels of the inner cavity pressing block 10-2 can simultaneously adhere to the bevels of the sealing frame. If they cannot adhere simultaneously, apply pressure-sensitive adhesive tape 17-1 layer by layer to the four bevels of the outer side of the inner cavity pressing block 10-2 until the inner cavity pressing block can simultaneously adhere to the four sides of the inner cavity of the sealing frame. Then, use bow-shaped clamps to clamp the inner cavity pressing block 10-2 to the sealing frame 4-1 and the drill mold body 10-1. Step 3: As Figure 18As shown, a heavy object is used to press the remaining flat surfaces of the sealing frame 4-1 against the drill mold body 10-1, making them fit together. Then, the ear clamping block 10-3 is pressed against the sealing frame positioning ear, and the outer side of the ear clamping block 10-3 is aligned with the corresponding shape on the drill mold body. The ear clamping block 10-3, the sealing frame 4-1, and the drill mold body 10-1 are then clamped together. Next, a drill bit is used to drill the insert mounting hole 3-2 and the ear positioning hole 8-1-A on the sealing frame 4-1 through the drill bushing 10-4 installed on the drill mold body 10-1. Step 4: As Figure 19 As shown, the sealing frame 4-1, the positioning pressure plate assembly 11-2, the honeycomb cover plate 19-1, and the insert 19-2 are assembled and positioned using positioning screws. Step 5: As Figure 20 As shown, screws are used to assemble and position the upper panel 20-1, the insert 20-2, and the positioning plate assembly 11-1, and position them on the adhesive clamp base plate assembly 20-3, so that the lower surface of the positioning plate 11-1 is in contact with the upper surface of the adhesive clamp base plate assembly 20-3. Step 6: As Figure 21 As shown, the perforated honeycomb core 21-1 is assembled into the corresponding position; Step 7: As Figure 22 As shown, Figure 19 The pre-assembled and covered with adhesive film and foam, the sealing frame, honeycomb cover plate and insert are assembled on top of the honeycomb core, so that the insert is installed into the corresponding insert opening in the honeycomb core; Step 8: As Figure 23 As shown, the bridging positioning block assembly 11-3 is assembled onto the positioning plate assembly 11-1, and the positioning pin 11-4 is inserted into the second bushing 11-3-Bb to complete the positioning of the bridging positioning block assembly 11-3 and the positioning plate assembly 11-1; then the positioning pin 11-4 is inserted into the first bushing 11-3-Ba to complete the positioning of the bridging positioning block assembly 11-3 and the positioning pressure plate assembly 11-2. Step 9: As Figure 24 As shown, fine-tune the position of the sealing frame 4-1 as needed, and then insert the positioning pin 24-1 into the positioning hole 8-1-A of the process positioning ear 8-1 to further ensure that the sealing frame 4-1 is aligned with the upper panel. Figure 5 The relative position.
