[0041] The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] An assembly tool for a fairing connection member, as Figures 1 to 7As shown in the figure, it includes an assembly platform 1, and a positioning boss 2 is provided on the upper end surface of the assembly platform. Several pressing plates 3 and several support frames 4 are installed on the upper end of the positioning boss. A positioning working surface 5 for the fairing body is provided around the outside of the positioning boss, and a mating working surface 6 for the fairing is provided on the outer wall of the positioning boss. As an example, the above-mentioned positioning boss is circular, and each of the pressing plates is uniformly arranged along the outer circumferential direction of the positioning boss. The above-mentioned support frame is detachably installed on the assembly platform through a connecting piece, which is convenient for assembly, storage and transportation after disassembly. A flanging punching drill sleeve 7 is installed on the part of the pressing plate that extends above the positioning working surface of the fairing body, and an inner support locator 8 is installed at the top of the support frame.

[0043] A support plate positioning working surface 9 for defining the height of the support is provided at the lower end of the inner support locator, a support side plate positioning working surface 10 for defining the angle of the support is provided on the side wall of the inner support locator, and a support punching drill sleeve 11 is installed at the cantilever end of the inner support locator; Support platforms 12 are symmetrically provided at the outer edge of the assembly platform, and hinge support locators 14 are detachably installed on the support platforms through horizontally arranged hinge support positioning pins 13. While ensuring the installation accuracy of the hinge support, the installation and disassembly efficiency can be improved, saving time and effort and being easy to operate.

[0044] The hinge support locator is integrally in a "U" shape structure, including a base 15 and side seats 16 on both sides of the base. Support platform positioning working surfaces 17 that cooperate with the support platform are provided on the inner surfaces of the two side seats, and cavities 18 are vertically opened on the side seats. In an alternative embodiment, sliding grooves are provided on both side walls of the support platform, and sliding rail structures 19 that cooperate with the sliding grooves are provided on the inner walls of the side seats of the hinge support locator. When installing the hinge support locator, just align the sliding rail structure with the sliding groove, push the hinge support locator to the fixed position, and insert the hinge support positioning pin, then the installation of the hinge support is quickly completed. When disassembling, first pull out the hinge support positioning pin, and then the hinge support locator can be directly slid outwards. The installation and disassembly are very convenient and efficient.

[0045] A hollow 20 is provided in the middle of the above-mentioned assembly platform, and the bottom of the assembly platform is supported by several legs 21, so that the bottom surface of the assembly platform is suspended. Workers can enter the inside of the fairing through the hollow to operate, and then complete the installation of the inner supports of the two large-size fairing half covers.

[0046] The above-mentioned pressing plate is positioned with the assembly platform through a positioning pin 22 and locked by a screw 23. As an example, each pressing plate is positioned with the assembly platform through two positioning pins, and positioning holes that cooperate with the positioning pins are provided on the assembly platform. The fixing accuracy of the pressing plate is high. The pressing plate can effectively fix the flanging position of the fairing body, and the flanging punching drill sleeve on the pressing plate can be used to drill holes in the flanging position, ensuring the hole position accuracy.

[0047] In an optional embodiment, the side seat and the assembly platform are also fixed through an auxiliary connecting member. Specifically, an auxiliary connecting member is provided on the base body, and the base body is directly fixed to the assembly platform through the auxiliary connecting member. Or, a connecting ear 24 is provided on the outer side of the side seat, and an auxiliary connecting member 25 is provided on the connecting ear. Under specific working conditions, the hinge support positioner can be fixed to the assembly platform by using the auxiliary connecting member, further improving the reliability of the installation and fixation of the hinge support positioner.

[0048] For example, when the size of the fairing product is large, the assembly platform can be made into a combined structure assembled by two split parts 26 of the assembly platform, such as Figure 5 As shown, a support body 27 is provided at the docking position of the split parts of the assembly platform. When the two split parts of the assembly platform are spliced, the support bodies of the two form the above-mentioned support platform together. By using the hinge support positioner fixed to the support platform, the two split parts of the assembly platform are fixed. By dividing the assembly platform into two parts, the problems of large size and heavy weight of the assembly platform equipped for the large fairing are solved. At the same time, by using the hinge support positioner to connect and fix the two split parts of the assembly platform, no additional connecting structures and components are required for the fixation between the two split parts of the assembly platform, which not only simplifies the structure but also reduces the assembly operation process. The design is ingenious and the assembly and use operations are simple.

[0049] It should be noted that since the hinge support is fixed on the side wall of the fairing body (half fairing), as Figure 6 shown, the fairing body (half fairing) straddles the two split parts of the assembly platform, and then the fairing is fixed by means of a pressing plate and an inner support on the inner support positioner, ensuring the stability of the fairing, and the stress condition of the split parts of the assembly platform is good, and there will be no problem of uneven stress.

[0050] A method for assembling a fairing connecting member using the above tooling includes the following steps:

[0051] S1. Vertically place a half fairing body 28 on the assembly platform so that the inner surface of the fairing body is matched with the working surface for matching the fairing body on the positioning boss. At the same time, make the lower end surface of the flanging at the bottom end of the fairing body be matched with the positioning working surface of the fairing body on the assembly platform;

[0052] S2. Position the pressing plate and the positioning boss through a positioning pin and lock the pressing plate with screws, so as to fix the flanging of the fairing body by means of the pressing plate, and drill holes in the fairing flanging by using the flanging drilling die on the pressing plate;

[0053] S3. Place the inner support 29 directly below the cantilever end of the inner support positioner and move it from bottom to top until the bottom plate 30 of the inner support abuts against the positioning working surface of the support bottom plate of the inner support positioner. At the same time, make the side plate 31 of the inner support be matched with the positioning working surface of the support side plate of the inner support positioner;

[0054] S4. Fix the inner support to the fairing body (by adhesive bonding or screw connection), and then drill holes in the inner support by means of the holes drilled in the support on the inner support locator;

[0055] S5. Place the other half of the fairing body on the assembly platform. After aligning and fastening the two halves of the fairing body, the operator enters from the hollow part at the bottom of the assembly platform, and repeats the operations in steps S1 - S4 to complete the flanging and hole drilling of the other half of the fairing body, the installation of the inner support, and the hole drilling of the inner support;

[0056] S6. Insert the rotating handle parts of the two hinge supports 32 on the same side into the cavities on both sides of the hinge support locator respectively, and then insert the hinge support locating pin along one side of the hinge support locator to fix the hinge support locator and the two hinge supports (the rotating handles) simultaneously;

[0057] S7. Fix the hinge support to the fairing body,

[0058] S8. Repeat steps S6 - S7 to complete the installation of the hinge support on the other side.

[0059] The above - mentioned hinge support is fixed to the fairing body by adhesive bonding or, alternatively, the hinge support is fixed to the fairing body by screw connection. Those skilled in the art can choose according to their needs.

[0060] The structure design of the present invention is reasonable. The fairing body can be firmly fixed on the assembly platform and effectively positioned. The pressure plate and the inner support locator are both positioned by locating pins and locked by screws, with high installation accuracy, ensuring the installation accuracy of the inner support and the hinge support and the hole - drilling accuracy. Using this assembly tooling, the assembly of the inner support and the hinge support can be efficiently completed, and high - precision machining of the hole positions of the structural components can be carried out. The operation is simple and the work efficiency is high.

[0061] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
