[0003] When installing the shell of an aerospace aircraft, positioning fixtures are required. The problem with the above-mentioned technology is that, in the existing technology, the shell is generally fixed with bolts when it is positioned. The fixing process is relatively complicated and the angle of the shell cannot be adjusted, thus reducing the fixing efficiency. Utility Model Content

The positioning spring is sleeved on the surface of the positioning rod and can be mounted on the mounting plate through the positioning rod. The mounting plate is fixed by the cooperation between the positioning rod and the positioning ring.

[0008] To improve the fixation of the housing, preferably, the fixing mechanism includes a lead screw, a threaded block, and a fixing plate. The surface of the lead screw is movably mounted in the middle of the mounting frame, and the right side of the lead screw is movably connected to the right side of the inner cavity of the mounting frame via a rotating shaft. The bottom of the threaded block is movably mounted in the bottom of the inner cavity of the mounting frame, and the surface of the lead screw is movably mounted in the middle of the threaded block. The bottom of the fixing plate is fixedly mounted in the top of the threaded block, and the bottom of the fixing plate is movably mounted in the top of the mounting frame. A slider is installed in the bottom of the fixing plate. By rotating the lead screw, the lead screw drives the threaded block to move through the threaded connection, and the threaded block drives the fixing plate to move, thus fixing the housing.

The slider can be installed on the fixed plate and the slide rod to limit the position of the fixed plate.

[0011] To improve the fixation of the shell, preferably, the inner wall of the fixing plate is equipped with an anti-slip plate, which is made of rubber. The anti-slip plate can be installed on the fixing plate, and the shell can be fixed by moving the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, by setting up a base, support frame, mounting frame, adjustment mechanism, positioning mechanism, fixing mechanism, and sliding rod, first installs the housing on the fixed plate. Rotating the lead screw causes the fixed plate to move via a threaded connection, which in turn moves the anti-slip plate, fixing the housing in place. Then, pulling the positioning rod moves the mounting plate, which in turn moves the mounting frame. Finally, the positioning rod is installed in the inner cavity of the positioning port, thus fixing the mounting plate. This solves the problem in existing technologies where the housing is typically fixed with bolts during positioning, which is a complex process and makes it impossible to adjust the angle of the housing, thus reducing fixing efficiency.
