Abstract

The invention provides a flexible clamp device for machining airplane composite material stringer and a method thereof. The flexible clamp device comprises a movable chuck assembly and a locating block assembly. The movable chuck assembly comprises a base, a fixed chuck and a movable chuck, the fixed chuck is fixedly connected with the base. The movable chuck is arranged on the base in a sliding mode and can move towards or away from the fixed chuck. The locating block assembly is arranged between the fixed chuck and the movable chuck and comprises a fixed locating block and a movable locating block. The fixedly locating block is connected to the fixed chuck, and a clearance is reserved between the fixed locating block and the top surface of the base. The movable locating block is connected to the movable chuck, and a clearance is reserved between the movable locating block and the top surface of the base. When the movable chuck moves towards the fixed chuck, the movable chuck drives the movable locating block to move towards the fixed locating block, so that a stringer is clamped between the movable locating block and the fixed locating block.

Description

technical field [0001] The invention relates to a flexible fixture device and a method for processing aircraft composite material stringers. The flexible fixture device can be installed on the numerical control processing equipment, and is used for the milling and cutting processing of the aircraft composite material long truss structure. Background technique [0002] As a typical structural part on the aircraft, the stringer is an important part of the aircraft wing panel, fuselage panel and empennage panel. The characteristics of this kind of parts are: it is mainly made of carbon fiber composite materials, and its edges need to be trimmed; it has a remarkable slender structure, with a length of up to 20,000mm and a width of only about 100mm; each aircraft contains long trusses. The quantity is very large, about 150 or so. These stringer structures are similar in form but vary in size. [0003] At present, the domestic aircraft composite material long truss is mainly pr...
