[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] Reference Figure 1 , two elevators are installed on the horizontal stabilizer A of the ground effect wing ship. The horizontal stabilizer A and each elevator ( Figure 1 The one shown in the figure is the right elevator B) which is designed with 5 hinge points a, b, c, f, e. The hinge points use shaft and hole to connect the horizontal stabilizer and the elevator together.

[0021] Initially, conventional marking positioning and prefabricated hole assembly methods were used to position the hinge support parts. Because the horizontal stabilizer and elevator are composite molded parts, there are many ribs inside the parts, and the inner surface is not accurate. After marking positioning, surface holes are installed at the hinge support points of the horizontal stabilizer and elevator. After the hinge support parts are installed, the theoretical axes of the five hinge supports are not on the same straight line, and the elevator cannot rotate freely around the axis of the shaft or is stuck and cannot rotate.

[0022] After analysis, it was found that the five hinge points were positioned and installed separately, resulting in large manufacturing errors at five locations, and the elevator could not rotate freely after installation.

[0023] To this end, the utility model embodiment provides a ground effect wing vehicle horizontal stabilizer and elevator hinge point connection positioning device, referring to Figure 2 , Figure 3 , including two symmetrically arranged positioning mechanisms 1, the two positioning mechanisms 1 are connected by a rotating shaft 2, the positioning mechanism 1 includes a support rod, a fixing clamp 11 and a hinge point positioning piece, a plurality of first support rods 12 arranged in parallel are vertically connected to a second support rod 13 at the upper part, the second support rod 13 is connected and fixed to the first support rod 12 by the fixing clamp 11, and a plurality of hinge point positioning pieces are arranged at the lower part of the second support rod 13.

[0024] Vertical rods 14 are provided at the lower parts of both ends of each of the first support rods 12 for supporting on the horizontal stabilizer forming mold.

[0025] First hinge support positioning members are provided at both ends of the second supporting rod 13, and multiple second hinge support positioning members are provided between the two first hinge support positioning members. The first hinge support positioning member includes a first support rod 15 and a first positioning plate 16. Two first positioning plates 16 are provided in parallel at the lower end of the first support rod 15. The first positioning plate 16 is parallel to the first supporting rod 12. The second hinge support positioning member includes a second support rod 17 and a second positioning plate 18. The lower end of the second support rod 17 is vertically connected to the middle part of a cross bar 19. The second positioning plates 18 are provided at both ends of the cross bar 19. The second positioning plates 18 are parallel to the second supporting rod 13.

[0026] Reference Figure 4 The rotating shaft 2 is rotatably connected between the first positioning plates 16 of the two positioning mechanisms 1 . A sleeve 20 is arranged outside two adjacent first positioning plates 16 of the two positioning mechanisms 1 , and the rotating shaft 2 is inserted into the sleeve 20 .

[0027] The fixing clamp 11 includes a horizontal plate, a vertical plate and an inclined plate. The horizontal plate is vertically connected to the vertical plate, and the inclined plate is connected to one side of the horizontal plate and the vertical plate. Strip holes are provided on the horizontal plate and the vertical plate. The fixing clamp 11 is fixed in the sliding grooves of the first support rod 12 and the second support rod 13 by bolts and nuts.

[0028] The hinge point positioning member and the support rod are both made of aluminum alloy profiles, and the fixing clamp 11 is made of aluminum alloy precision casting, with anodized surface, good rigidity and corrosion resistance.

[0029] The positioning device of the utility model is used before the upper and lower skins of the horizontal stabilizer are molded, and after the base body for installing the hinge support part is positioned and holes are made, the hinge support part is installed at the made hole, which reduces the difficulty of assembly technology and shortens the production cycle.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
