[0041] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] The utility model provides an auxiliary assembly device, such as Figure 1-3 As shown, the auxiliary assembly device is used to assemble the adapter 100 to the target structure. The auxiliary assembly device includes a positioning structure 1, which includes a detachably connected limiting plate 11 and a positioning plate 12; the limiting plate 11 can limit the relative position of the positioning structure 1 and the adapter 100; the positioning plate 12 is provided with a plurality of positioning holes 121, and the plurality of positioning holes 121 are used to locate the drilling positions of the adapter 100 and the target structure.

[0044] like Figure 1-3 As shown, when the adapter 100 is to be assembled to the target structure, the adapter 100 is first preliminarily positioned on the target structure, and then the relative positions of the positioning structure 1 and the adapter 100 are limited by the limiting plate 11, so that the relative positions of the positioning structure 1, the adapter 100 and the target structure are relatively fixed. Then, holes are directly drilled through the adapter 100 and the target structure through the positioning holes 121 on the positioning plate 12 to form a plurality of rivet connection holes. Alternatively, the positioning holes 121 on the positioning plate 12 are marked to locate the hole positions, and then the positioning plate 12 is detached and holes are drilled on the adapter 100 to penetrate the adapter 100 and the target structure to form a plurality of rivet connection holes. Then, the rivets are inserted into the rivet connection holes, and the adapter 100 is riveted to the target structure through the rivets. This realizes the assembly of the adapter 100 and the target structure.

[0045] Therefore, the auxiliary assembly device can quickly and efficiently determine the opening position of the rivet connection hole, and can quickly and efficiently drill holes in the adapter 100 and the target structure to form the rivet connection hole, saving time and effort; secondly, the position of the formed rivet connection hole is high in accuracy.

[0046] Specifically, in this embodiment, the target structure is an aircraft radome. By adopting the above-mentioned auxiliary assembly device, the opening position of the rivet connection hole can be quickly and efficiently determined, and the adapter 100 and the aircraft radome can be quickly and efficiently drilled to form the rivet connection hole, saving time and labor; secondly, the position accuracy of the formed rivet connection hole is high, which can effectively improve the connection reliability of the adapter 100 and the aircraft radome.

[0047] Specifically, after the adapter 100 and the aircraft radome are assembled, the antenna is installed in the first mounting hole 1101 of the adapter 100. This allows the antenna to be installed on the aircraft radome, which can effectively improve the reliability of connecting the antenna to the aircraft radome. Specifically, the antenna is threadedly connected to the adapter 100 by screws. The specific structure of the aircraft radome belongs to the prior art and will not be described in detail here.

[0048] Among them, Figure 1-4 As shown, the limit plate 11 includes a limit plate body 111 connected to each other, and two first plug-in limit parts 112 connected to the two ends of the limit plate body 111, and the outer peripheral wall of at least one first plug-in limit part 112 is provided with a second plug-in limit part 113; the positioning plate 12 is detachably connected to the limit plate body 111; the adapter 100 includes a mounting part 110 and a adapter part 120 connected to the outer periphery of the mounting part 110, the mounting part 110 is provided with a first mounting hole 1101 connected to the interior of the target structure, and the inner peripheral wall of the first mounting hole 1101 is provided with a third plug-in limit part 1102; when the two first plug-in limit parts 112 are both plugged into the first mounting hole 1101, the second plug-in limit part 113 and the third plug-in limit part 1102 are plugged and matched, and the limit plate body 111 and the positioning plate 12 are both overlapped on the adapter part 120 and are both in contact with the upper end surface of the adapter part 120. Such arrangement enables the limiting plate 11 to limit the relative position of the positioning structure 1 and the adapter 100 .

[0049] Specifically, the positioning plate 12 and the limiting plate body 111 are detachably connected by means of threaded connection. In other embodiments, the positioning plate 12 and the limiting plate body 111 can be detachably connected by means of snap connection or plug connection.

[0050] Specifically, the first plug-in limiting portion 112 is arc-shaped and matches the shape of the first mounting hole 1101. One of the second plug-in limiting portion 113 and the third plug-in limiting portion 1102 is a plug block, and the other is a slot, and the plug block is plugged into the slot, so as to limit the relative position of the limiting plate 11 and the adapter 100 along the circumferential direction, and prevent the limiting plate 11 from rotating relative to the adapter 100.

[0051] Furthermore, in this embodiment, if Figure 3 and Figure 4 As shown, the first mounting hole 1101 is a stepped cylindrical hole.

[0052] Furthermore, in this embodiment, if Figure 3 and Figure 4 As shown, the inner wall of the first mounting hole 1101 is provided with an insert block, one of the first plug-in limiter 112 is provided with a second plug-in limiter 113, the second plug-in limiter 113 is a slot recessed on the outer periphery of the first plug-in limiter 112, and the insert block is plugged into the slot. Further, when the antenna is assembled in the first mounting hole 1101, the insert block is used to prevent the antenna from being plugged in reverse. As an alternative, the inner wall of the first mounting hole 1101 is provided with a slot, the second plug-in limiter 113 is an insert block recessed on the outer periphery of the first plug-in limiter 112, and the insert block is plugged into the slot.

[0053] Specifically, the target structure is provided with a third mounting hole for plugging with the mounting portion 110 , and the third mounting hole is communicated with the interior of the target structure.

[0054] Among them, the plate formed by the limiting plate body 111 and the positioning plate 12 is the first plate, the adapter part 120 is the second plate, and the target structure includes a third plate for connecting with the adapter part 120; the first plate, the second plate and the third plate are all curved plates; or, the first plate, the second plate and the third plate are all flat plates.

[0055] It can be understood that the third mounting hole is arranged on the third plate of the target structure.

[0056] Specifically, in this embodiment, Figure 1-5 As shown, the first plate, the second plate and the third plate are all curved plates. The adapter 120 of the adapter 100 and the third plate of the target structure are drilled through the adapter 120 and the target structure to form rivet connection holes. This enables the adapter 100 and the aircraft radome to be assembled and formed quickly, efficiently and accurately, and the antenna to be assembled to the aircraft radome. It can be understood that when the first plate, the second plate and the third plate are all flat plates, the second plate and the third plate can also be assembled and formed quickly, efficiently and accurately.

[0057] Among them, Figure 1 and Figure 6-8 As shown, the auxiliary assembly device also includes a support structure 2 and a locking structure 3. The support structure 2 can pass through the positioning structure 1 and the adapter 100 and be distributed inside the target structure. The locking structure 3 can lock the distribution position of the support structure 2 inside the target structure so that the support structure 2 can support the rivet at any drilling position. This arrangement can support the rivet riveting adapter 120 and the target structure, and can assemble the adapter 100 and the target structure into shape.

[0058] Specifically, Figure 1-8As shown, a second mounting hole 13 is formed between the positioning plate 12 and the limiting plate 11; the mounting portion 110 of the adapter 100 is provided with a first mounting hole 1101 connected to the interior of the target structure, and the first mounting hole 1101 is also connected to the second mounting hole 13; the support structure 2 can be distributed inside the target structure through the second mounting hole 13 and the first mounting hole 1101. When the adapter portion 120 of the adapter 100 is to be riveted to the third plate of the target structure by rivets, the support structure 2 is firstly set inside the target structure through the second mounting hole 13 and the first mounting hole 1101; the adapter portion 120 and the target structure are riveted by the support structure 2.

[0059] Alternatively, if Figure 1-3 As shown, there are two positioning plates 12, which are symmetrically distributed on both sides of the limiting plate 11 and are connected to the limiting plate 11. A second mounting hole 13 is formed between each positioning plate 12 and the limiting plate 11. This arrangement enables the positions of multiple rivet connection holes on the adapter 120 to be directly located, thereby further improving the efficiency of assembling the adapter 100 with the target structure; secondly, the two second mounting holes 13 also facilitate the setting of the support structure 2 inside the target structure.

[0060] Among them, Figure 1-5 , Figure 7 and Figure 8 As shown, the locking structure 3 includes a connecting column 31 and a locking member 32. The connecting column 31 is fixedly arranged on the limiting plate 11 and can pass through the first mounting hole 1101 and extend into the target structure; the connecting column 31 is provided with an axial limiting surface, the supporting structure 2 can be rotatably sleeved on the connecting column 31 and abut against the axial limiting surface of the connecting column 31, and the locking member 32 is threadedly connected to the connecting column 31 and can abut against the supporting structure 2 along the axial direction of the connecting column 31. Such a setting can realize that the supporting structure 2 is set in the target structure, and the supporting structure 2 can be rotatably adjusted so that the supporting structure 2 can be distributed directly below any rivet connection hole and support the rivet in the corresponding rivet connection hole; after the setting position of the supporting structure 2 is adjusted, the locking member 32 is used to lock the supporting structure 2 to the connecting column 31. It can be understood that the supporting structure 2 rotates around the central axis of the connecting column 31. This arrangement enables the locking structure 3 to lock the distribution position of the supporting structure 2 inside the target structure, and enables the supporting structure 2 to support the rivet at any drilling position; secondly, it effectively avoids the problem in the prior art that the top iron cannot be used in the aircraft radar cover, so that the adapter 100 and the target structure can be riveted by traditional riveting, effectively reducing the riveting cost and effectively ensuring the riveting yield.

[0061] Specifically, in this embodiment, the locking member 32 is a locking nut.

[0062] Specifically, the locking structure 3 further includes an adjusting gasket, which can be sleeved on the connecting column 31, and the adjusting gasket is used to adjust the distribution position of the supporting structure 2 in the target structure along the axial direction of the connecting column 31. By increasing or decreasing the number of adjusting gaskets to adjust the distribution position of the adjusting gaskets, the distribution position of the supporting structure 2 can be adjusted along the axial direction of the connecting column 31, so that the distance between the supporting structure 2 and the rivet connecting hole can be adjusted, leaving a deformation gap for the rivet.

[0063] It is understandable that, along the axial direction of the connecting column 31, the adjusting gasket can be distributed between the axial limiting surface and the supporting structure 2, or between the supporting structure 2 and the locking member 32, so as to achieve the ability to adjust the distribution position of the supporting structure 2 along the axial direction of the connecting column 31.

[0064] Alternatively, if Figure 1 , Figure 7 and Figure 8 As shown, a handle 33 is fixedly provided at one end of the connecting column 31 extending out of the limiting plate body 111. The handle 33 facilitates the carrying of the integral structure formed by the connecting column 31 and the limiting plate body 111.

[0065] Among them, Figure 1 and Figure 6-8 As shown, the support structure 2 includes a connecting portion 21 and a supporting portion 22 connected to each other, and the locking structure 3 can lock the distribution position of the connecting portion 21 inside the target structure, and the supporting portion 22 can support the rivet at any drilling position. It can be understood that when the distribution position of the connecting portion 21 is adjusted along the axial direction of the connecting column 31, the supporting portion 22 is driven to move synchronously to adjust the distance between the supporting portion 22 and the rivet connection hole. By rotating the connecting portion 21 around the central axis of the connecting column 31, the supporting portion 22 is driven to rotate synchronously to adjust the support portion 22 to be distributed directly below the rivet connection hole.

[0066] Specifically, an escape space is formed between the connecting portion 21 and the supporting portion 22 , and the escape space is used to escape the mounting portion 110 .

[0067] Furthermore, if Figure 1 and Figure 4-8 As shown, the mounting portion 110 includes a first sub-mounting portion 1103 and a second sub-mounting portion 1104 connected to each other, and the first sub-mounting portion 1103 is also connected to the adapter portion 120; the first mounting hole 1101 passes through the first sub-mounting portion 1103 and the second sub-mounting portion 1104. A reinforcing rib 1105 is also provided between the first sub-mounting portion 1103 and the second sub-mounting portion 1104, and the support portion 22 is also provided with an avoidance hole 221 connected to the avoidance space, and the reinforcing rib 1105 can partially pass through the avoidance hole 221.

[0068] Such arrangement can effectively adjust the distance between the support portion 22 and the rivet connection hole, and can effectively adjust the support portion 22 to be distributed directly below the rivet connection hole.

[0069] Preferably, the number of the supporting parts 22 is multiple, such as Figure 1 and Figure 6-8 As shown, a plurality of support portions 22 are spaced apart along the circumference of the connecting portion 21. The number of adjustments of the support structure 2 can be reduced, thereby further improving the efficiency of assembling the adapter 100 and the target structure. In this embodiment, the exemplary number of support portions 22 is two, and the two support portions 22 are spaced apart and distributed at both ends of the length direction of the connecting portion 21.

[0070] The utility model also provides an auxiliary assembly method, which is implemented in the above-mentioned auxiliary assembly device. By adopting the auxiliary assembly method, the efficiency of assembling the adapter 100 and the target structure can be effectively improved; secondly, it can effectively avoid the problem of being unable to use the top iron in the aircraft radome in the prior art, so that the adapter 100 and the target structure can be riveted by traditional riveting, which effectively reduces the riveting cost and the difficulty of the riveting construction personnel, and ensures the riveting yield. Fig. 9 As shown, the auxiliary assembly method includes:

[0071] S100, fix the relative positions of the target structure, the adapter 100 and the positioning structure 1.

[0072] Specifically, step S100 includes:

[0073] S110, inserting the mounting portion 110 into the target structure, so that the adapter portion 120 overlaps the target structure and fits with the upper end surface of the target structure.

[0074] Specifically, step S110 includes: inserting the mounting portion 110 of the adapter 100 into the third mounting hole of the third plate of the target structure, so that the adapter portion 120 of the adapter 100 overlaps the third plate and fits with the upper end surface of the third plate, so as to achieve the relative position of the fixed adapter 100 and the target structure.

[0075] S120, insert the two first plug-in limiting parts 112 into the mounting part 110, so that the limiting plate body 111 and the positioning plate 12 are both overlapped on the adapter part 120 and are both in contact with the upper end surface of the adapter part 120, so as to achieve the relative position of the fixed positioning structure 1 and the adapter 100.

[0076] Thus, the relative positions of the target structure, the adapter 100 and the positioning structure 1 are fixed. The positioning method is simple and easy to operate.

[0077] S200 , drilling holes through the adapter 100 and the target structure according to the positioning holes 121 to form a plurality of rivet connection holes.

[0078] It can be understood that the arrangement positions of the multiple rivet connection holes correspond one-to-one to the arrangement positions of the multiple positioning holes 121 .

[0079] Specifically, when the diameter of the rivet connection hole is less than or equal to the diameter of the positioning hole 121, step S200 includes: passing the drill bit through the positioning hole 121 to drill through the adapter 100 and the target structure to form a rivet connection hole. This allows multiple rivet connection holes to be drilled. The positioning hole 121 can guide the drill bit to move along the depth direction of the positioning hole 121, thereby further improving the accuracy of the rivet connection hole obtained by drilling.

[0080] Specifically, when the aperture of the rivet connection hole is less than or equal to the aperture of the positioning hole 121, or the aperture of the rivet connection hole is larger than the aperture of the positioning hole 121, step S200 includes:

[0081] S210 , marking the location of the rivet connection hole through the positioning hole 121 toward the adapter 120 .

[0082] S220 , detach the positioning plate 12 from the limiting plate body 111 .

[0083] S230 , drilling holes through the adapter 120 and the target structure according to the marked positions to form rivet connection holes.

[0084] It is also possible to drill a plurality of rivet connection holes.

[0085] S300, inserting a rivet into the rivet connection hole. It is understandable that the specification of the rivet matches the aperture of the rivet connection hole.

[0086] Before step S400 , the method further includes: passing the support structure 2 through the second mounting hole 13 and the first mounting hole 1101 and distributing it in the target structure; and connecting the support structure 2 to the limiting plate body 111 .

[0087] S400, adjusting the distribution position of the support structure 2 so that the distance between the support structure 2 and the rivet connection hole is a set deformation allowance gap, and the rivet is supported on the support structure 2.

[0088] Specifically, step S400 includes:

[0089] S410, moving the support structure 2 along the depth direction of the rivet connection hole so that the distance between the support structure 2 and the rivet connection hole is a set deformation allowance gap.

[0090] Specifically, by replacing adjustment gaskets of different numbers and thicknesses, the support structure 2 is moved to a desired position along the depth direction of the rivet connection hole, so that the distance between the support structure 2 and the rivet connection hole is a set deformation allowance gap.

[0091] The deformation allowance gap is set to match the specifications of the rivets. The value of the set deformation allowance gap corresponding to each specification of rivets is different. The set deformation allowance gap is an empirical value obtained from a large number of previous tests.

[0092] It can be understood that the depth direction of the rivet connection hole is parallel to the axial direction of the connection column 31 .

[0093] S420 , rotating the support structure 2 so that the support structure 2 is distributed directly below the rivet connection hole, and the rivets in the rivet connection hole are supported on the support structure 2 .

[0094] Specifically, the support structure 2 is rotated with the central axis of the connecting column 31 as the rotation center line, so that the support portion 22 of the support structure 2 is distributed directly below the rivet connection hole, and the rivet in the rivet connection hole is supported on the support portion 22.

[0095] S500 , riveting and fixing the adapter 100 and the target structure by rivets.

[0096] After step S500, the method further includes:

[0097] S600: Determine whether there is a rivet connection hole without a rivet.

[0098] If there are rivet connection holes without rivets, rivets are inserted into the rivet connection holes without rivets, and steps S400 to S500 are performed until all rivet connection holes are provided with rivets, at which point the adapter 100 is assembled with the target structure.

[0099] Preferably, when performing step S500, the adapter 100 and the target structure are riveted and fixed by rivets one by one from the center of the adapter 100 to the outer periphery of the adapter 100. Such a configuration can reduce the risk that the adapter 120 deforms during the riveting process, resulting in the remaining rivet connection holes being unable to be riveted to the adapter 120 and the target structure.

[0100] Preferably, when executing step S500, for a plurality of rivet connection holes distributed on the same circumference, two rivet connection holes distributed on the same straight line sequentially pass through the rivet riveting adapter 120 and the target structure, wherein the straight line is a straight line passing through the center of the circumference. Such an arrangement can further reduce the risk that the remaining rivet connection holes cannot be provided with the rivet riveting adapter 120 and the target structure due to deformation of the adapter 120 during the riveting process.

[0101] Therefore, by adopting the above-mentioned auxiliary assembly method to assemble the adapter 100 and the target structure, the efficiency of assembling the adapter 100 and the target structure can be effectively improved; secondly, it can effectively avoid the problem in the prior art that the top iron cannot be used in the aircraft radar cover, so that the adapter 100 and the target structure can be riveted by traditional riveting, which effectively reduces the riveting cost and the working difficulty of the riveting construction personnel, thereby ensuring the riveting yield.
