[0002] In the assembly process of a certain type of passenger aircraft, components such as boundary beams, floor longitudinal beams, and floor transverse beams need to be positioned and assembled. Because the boundary beams have relatively poor rigidity, their position can easily change during assembly due to riveting vibrations and other factors. Therefore, positioning devices are needed to fix the boundary beams during assembly to ensure that their assembly position meets requirements.

[0015] Please see Figures 1-3An aircraft boundary beam locator includes a locator 1, a web plate locator 2, a hook-shaped clamping device 3, and an angle iron 4. The locator 1 consists of a positioning plate 1-1 and a bushing 1-2. The bushing 1-2 is installed in three Ф12H7 holes in the positioning plate 1-1 for measuring the position of the boundary beam locator when installed using a laser tracker. The positioning plate 1-1 has engraved lines on its contact surface with the product and a raised section for positioning the boundary beam in the flight direction. The web plate locator 2 consists of an outer retaining member 2-1, a body 2-2, a first screw 2-3, a cylindrical pin 2-4, and a precision bolt 2-5. The outer retaining member 2-1 has a slot in the middle, and the body 2-2 is installed in the slot using the first screw 2-3. The first screw 2-3 has a handle to facilitate movement of the body 2-2 within the slot of the outer retaining member 2-1. The side of the body 2-2 is used for positioning the boundary beam. The web plate is positioned by a web plate locator 2, which is mounted on the locator by a precision bolt 2-5. A cylindrical pin 2-4 is inserted into the locator 1, the outer edge stop 2-1, and the body 2-2 to determine the position of the body 2-2. The hook clamp 3 consists of a handle nut 3-1, a hook 3-2, a polyurethane pad (white) 3-3, and a second screw 3-4. The handle nut 3-1 and the hook 3-2 are connected by threads. The polyurethane pad (white) 3-3 is mounted on the hook 3-3 by the second screw 3-4. The hook clamp 3 is installed in the three holes of the locator 1 to clamp the product. The angle iron 4 is used to connect the locator to the tooling. When the product needs to be removed from the shelf, the cylindrical pin 2-4 is pulled out, and the first screw 2-3 is pushed to guide the body 2-2 backward along the groove of the outer edge stop 2-1, ensuring that the boundary beam locator and the product have a sufficient safe distance.
