Problems solved by technology

With the development of modern processing technology and equipment, the lugs present a trend of large size, high precision, and composite type, which causes great inconvenience to positioning and clamping
[0003] There are multiple sets of lug joints on large structural parts. In order to achieve its safe and fast fixation, the traditional clamping method adopts a fixed type, which has poor versatility, takes up a large space, is not flexible in use, and cannot achieve multi-degree-of-freedom adjustment. Therefore, a design A versatile and flexible lug joint locking mechanism is an inevitable trend

Description

technical field [0001] The invention belongs to the technical field of lug joint locking devices, and in particular relates to a multi-degree-of-freedom adjustable lug joint locking mechanism. Background technique [0002] Joints are commonly used connection structures on aircraft. During the assembly process of the aircraft, the fork lug joint is used to realize the connection between the structural parts, and the lugs on the reinforcement frame are connected and fixed with the lugs on the corresponding structural part girder with bolts. With the development of modern processing technology and equipment, the lugs present a trend of large size, high precision, and compound type, which cause great inconvenience to positioning and clamping. [0003] There are multiple sets of lug joints on large structural parts. In order to achieve its safe and fast fixation, the traditional clamping method adopts a fixed type, which has poor versatility, takes up a large space, is not flexi...
