Embodiment Construction

[0023] see Figure 1 to Figure 5 , a flexible compression mechanism, including a plurality of flexible compression units, the flexible compression unit includes a housing 1, a rubber wheel 3, a spring 6, and a connecting mechanism; the housing 1 is an internal hollow structure, and one end is provided with a single-ear insert 7. The other end is provided with a double-ear notch 8, and the double-ear notch 8 is provided with a limiting arc-shaped groove 10 matched with the single-ear insert 7. The rubber wheel 3 is installed on the lower part of the housing 1 through a connecting mechanism. A spring 6 is arranged above the wheel 3. Under the action of the spring 6, the rubber wheel 3 can be pressed and separated from the surface of the part to be pressed. The flexible pressing mechanism is composed of a plurality of pressing units according to the length of the part to be pressed. The previous one The one-ear insert 7 of the pressing unit is connected with the double-ear notch ...

Abstract

The invention discloses a flexible pressing mechanism and a pressing method thereof. The flexible pressing mechanism is composed of multiple flexible pressing units, the flexible pressing units comprise housings, rubber wheels, springs and connecting mechanisms, the flexible pressing unis are mutually connected through pins and can be rotated around the pins, locking is conducted after the included angle between the adjacent flexible pressing units is adjusted according to the shape of skin, and pulling rings are arranged at the two ends of the flexible pressing mechanisms and fixed to a framework through fastening pliers which are fixed to a fixture frame. According to the mechanism, the pressing adapting to skins of different shape curvatures is achieved through different angle combination of the flexible pressing units.

Description

technical field [0001] The application relates to the assembly and manufacturing technology of aircraft components, in particular to a flexible pressing mechanism and a pressing method thereof. Background technique [0002] During the assembly process of aircraft panel components, in addition to the installation of the skin parts with curved surface shape, it is necessary to set up the inner positioning clamp, and also need to be pressed to prevent the drill or riveting during the hole making and connection process. The vibration and impact of the gun cause the position of the skin parts to deviate, which affects the installation accuracy of the wall panel components. Generally, when pressing, the shape matching the outer surface of the skin is used to compress the clamping plate. The shape of the multi-station and multi-section forms a complete skin shape to achieve the purpose of overall pressing of the skin parts. The clamping plate is tracked by the laser. This kind of ...
