Description

TECHNICAL FIELD

[0001] The utility model relates to aircraft assembly technical field especially, relates to a universal suction cup device for aircraft assembly. BACKGROUND

[0002] Universal suction cup devices are very useful tools in aircraft assembly, especially when handling large, heavy, or precision parts. These devices are commonly used to lift and move various types of components, such as fuselage sections, wings, or other parts that require precise alignment. They provide stable and flexible operating capabilities, allowing workers to complete assembly tasks more safely and efficiently.

[0003] In the Chinese patent with the authorization announcement number CN221138613U, a universal suction cup device for aircraft assembly is disclosed, which includes a ball socket, a suction cup assembly, and a anti-dropping assembly. The top end of the ball socket is recessed in the middle to form a spherical recess, and the bottom end of the suction cup assembly is sealed and embedded in the spherical recess, and rotates with the spherical recess. A cavity is provided in the middle of the ball socket, and the top end of the cavity is communicated with the spherical recess. An air extraction port is provided on one side of the middle of the ball socket, which is horizontally arranged and communicated with the cavity. An air extraction hole is provided on the suction cup assembly, which is vertically arranged. The device also includes a positioning block for positioning the aircraft skin, which is vertically connected to the top center of the suction cup assembly. A ring-shaped recess is provided at the bottom end of the suction cup assembly. When the center line of the suction cup assembly coincides with the center line of the ball socket, the bottom end of the air extraction hole is communicated with the cavity through the ring-shaped recess. The utility model has a simple structure, can stably and quickly adsorb the aircraft skin, and has a positioning function.

[0004] However, when this universal suction cup device is idle or working, dust or small particles may enter the interior of the universal suction cup through the air extraction hole and accumulate between the ball head and the magnetic ring, thereby reducing the magnetic attraction force and causing the attraction force between the ball head and the magnetic ring to decrease, resulting in falling off during the working process and having certain safety hazards, so it is urgent to improve.
