Based on this, drone wings need to undergo static load testing after assembly. Currently, different tooling is used for drone assembly positioning and static load testing. Both of these require special design, resulting in a large number of parts and poor tooling versatility. Utility Model Content

[0004] The purpose of this utility model is to provide a static load tooling and tooling assembly for wing assembly, which can be used for both assembly positioning and static load testing, and has strong versatility.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] One aspect provides a static load tooling for wing assembly, which includes:

[0007] The mounting bracket includes a mounting body, a first fixing block is provided in the middle of the mounting body, and a second fixing block is provided at the first end of the mounting body. The first fixing block and the second fixing block are located on the same side of the mounting body. Both the first fixing block and the second fixing block are provided with first fixing holes to fix the front and rear spars of the wing. The top surface of the mounting body is provided with multiple positioning grooves for fixing the assembly mold of the wing.

[0008] A fixed base plate is provided, and the seat body is detachably mounted on the fixed base plate so that there is a gap between the first fixing block and the second fixing block and the fixed base plate.

[0009] In some embodiments, the top surface height of the second fixing block is lower than the top surface height of the first fixing block.

[0010] In some embodiments, the base body is further provided with a third fixing block and a fourth fixing block. The third fixing block is collinear with the first fixing block and is located on opposite sides of the base body. The fourth fixing block is collinear with the second fixing block and is located on opposite sides of the base body. Both the third fixing block and the fourth fixing block are detachably connected to the fixing base plate.

[0011] In some embodiments, the wing assembly static load fixture further includes a first pad corresponding to the third fixing block and a second pad corresponding to the fourth fixing block. The first pad and the second pad are detachably disposed on the fixing base plate. The third fixing block is detachably connected to the first pad, and the fourth fixing block is detachably connected to the second pad.

[0012] In some embodiments, the wing assembly static load fixture further includes a first fixing member, and the third fixing block and the first pad block have corresponding second fixing holes; the first fixing member passes through the second fixing hole and is connected to the fixing base plate;

[0013] And / or, the wing assembly static load fixture further includes a second fixing member, and the fourth fixing block and the second pad block have corresponding third fixing holes; the second fixing member passes through the third fixing hole and is connected to the fixing base plate.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 3 As shown, this utility model provides a static load fixture for wing assembly, which can be used for the assembly and positioning of UAVs and the static load test of wings. Of course, it can also be used for other aircraft with wings. The static load fixture for wing assembly includes a mounting base 1 and a fixed base plate 2. The mounting base 1 includes a base body 11. A first fixing block 12 is provided in the middle of the base body 11, and a second fixing block 13 is provided at the first end of the base body 11. The first fixing block 12 and the second fixing block 13 are located on the same side of the base body 11. The first fixing block 12 and the second fixing block 13 are both provided with first fixing holes 14 to fix the front and rear beams of the wing. The top surface of the base body 11 is provided with multiple positioning grooves 15 for fixing the assembly mold of the wing. The base body 11 is detachably mounted on the fixed base plate 2 so that there is a gap between the first fixing block 12 and the second fixing block 13 and the fixed base plate 2.

[0034] The mounting base 1 is fixed by the base plate 2, and then the front and rear beams of the wing are fixed by the first fixing holes 14 on the first fixing block 12 and the second fixing block 13, thus fixing the wing to the mounting body 11. This creates a gap between the first fixing block 12 and the second fixing block 13 and the base plate 2, allowing for static load testing of the wing and avoiding interference. In addition, the positioning groove 15 on the top surface of the mounting body 11 can be used to fix the mold for assembly, thereby achieving assembly fixation. Thus, a single tooling can achieve both static load testing and assembly positioning, improving the versatility of the tooling.

[0035] It should be noted that the number of positioning grooves 15 is not specifically limited, and their positions can vary depending on the mold.

[0036] like Figures 1 to 3As shown, in some embodiments, in order to better adapt to the wing orientation, the top surface height of the second fixing block 13 is lower than the top surface height of the first fixing block 12, thereby making it easier to adapt to the height of the rear beam and the front beam.

[0037] To improve the connection strength during static load testing, in some embodiments, a third fixing block 16 and a fourth fixing block 17 are provided on the base body 11. The third fixing block 16 is collinear with the first fixing block 12 and located on opposite sides of the base body 11. The fourth fixing block 17 is collinear with the second fixing block 13 and located on opposite sides of the base body 11. Both the third fixing block 16 and the fourth fixing block 17 are detachably connected to the fixed base plate 2. This increases the number of connection points on the base body 11 and enhances the connection strength. Furthermore, the connection between the third fixing block 16 and the fourth fixing block 17 and the base body 11 can also provide an anti-overturning moment, greatly enhancing the anti-overturning capability and ensuring the stability of the static load test.

[0038] like Figure 2 As shown, specifically, in order to better fix the third fixing block 16 and the fourth fixing block 17, the wing assembly static load fixture also includes a first pad 3 corresponding to the third fixing block 16 and a second pad 4 corresponding to the fourth fixing block 17. So that during fixing, the first pad 3 can be placed between the third fixing block 16 and the fixing base plate 2, and the second pad 4 can be placed between the fourth fixing block 17 and the fixing base plate 2. The first pad 3 and the fixing base plate 2 are detachably connected, and the third fixing block 16 and the first pad 3 are detachably connected; the second pad 4 and the fixing base plate 2 are also detachably connected, and the fourth pad 4 and the second pad 4 are detachably connected, thereby achieving stable fixing.

[0039] More specifically, the static load tooling for wing assembly also includes a first fixing member, and the third fixing block 16 and the first pad 3 have corresponding second fixing holes 18; the first fixing member passes through the second fixing hole 18 and is connected to the fixing base plate 2. For example, the fixing base plate 2 is provided with corresponding screw holes, the second fixing hole 18 can be a through hole, and the first fixing member can be, but is not limited to, an M8 bolt, so that the first fixing member and the first pad 3 pass through the second fixing hole 18 through the M8 bolt and are screwed onto the fixing base plate 2.

[0040] Similarly, the static load fixture for wing assembly also includes a second fixing component. The fourth fixing block 17 and the second pad block 4 have corresponding third fixing holes 19. The second fixing component passes through the third fixing hole 19 and is connected to the fixing base plate 2. For example, the second fixing component also uses an M8 bolt, the third fixing hole 19 can be a through hole, and the fixing base plate 2 is provided with screw holes corresponding to the third fixing hole 19 for screw connection and fixing. The specific details will not be elaborated further.

[0041] The third fixing block 16 is collinear with the first fixing block 12, and the fourth fixing block 17 is collinear with the second fixing block 13. When performing assembly positioning, the first pad 3 and the second pad 4 can also be removed. The second fixing hole 18 on the third fixing block 16 and the third fixing hole 19 on the fourth fixing block 17 are used to connect and position with the assembly mold, thereby ensuring the accurate positioning of the assembly mold.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments, in order to fix the card holder 1 to the fixed base plate 2, a plurality of fourth fixing holes 110 are provided on the top surface of the seat body 11 from the first end of the seat body 11 to the second end of the seat body 11. The wing assembly static load tooling also includes a third fixing member, which passes through the fourth fixing holes 110 and is fixed to the fixed base plate 2. The fixing principle is the same as that of the first and second fixing members. The third fixing member can also be selected with an M8 bolt. The fourth fixing hole 110 can be a through hole. The fixed base plate 2 is provided with screw holes corresponding to the fourth fixing holes 110, so that the third fixing member is screwed onto the fixed base plate 2 for fixation.

[0043] It is understandable that the aforementioned fourth fixing hole 110 can also be provided in the positioning groove 15, thereby facilitating the distribution of the fourth positioning holes. It should be noted here that the fourth positioning hole without a third fixing member is not limited to its use for auxiliary positioning during assembly.

[0044] In some embodiments, to improve structural strength, the fixing base plate 2 and the card holder 1 may be, but are not limited to, made of 45 steel. The base body 11, the first fixing block 12, the second fixing block 13, the third fixing block 16, and the fourth fixing block 17 may be integrally formed for ease of molding. The fixing base plate 2 may be, but is not limited to, a 3cm thick plate to ensure connection strength.

[0045] like Figure 2 As shown, in some embodiments, the wing assembly static load fixture also includes a fixing cylinder 111, which is fixed to the second end of the base body 11. That is, the fixing cylinder 111 and the second fixing block 13 are arranged on opposite sides of the first fixing block 12, and the fixing cylinder 111 and the first fixing block 12 are located on the same side of the base body 11. Thus, during the static load test, the fixing cylinder 111 can be inserted into the anti-torsion seat of the wing to prevent overall torsion.

[0046] This application also provides a tooling assembly, which includes two sets of the above-mentioned wing assembly static load tooling, wherein the mounting brackets 1 in the two sets of wing assembly static load tooling are mirror images of each other, thereby adapting to the left and right wings respectively.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
