Abstract

A large thin-wall cylindrical component automatic abut-joint assembling flexible positioning device comprises a chassis, at least two pairs of vertical supporting mechanisms arranged on the chassis movably, a movable platform located on the vertical supporting mechanisms and a flexible bracket; each vertical supporting mechanism and the chassis are connected through a two-dimensional sliding railto achieve plane independent motion, the vertical supporting mechanisms and the movable platform are connected in a ball socket manner so as to achieve six-freedom-degree gesture adjusting of the movable platform and the flexible bracket. The device has the beneficial effects of being high in smoothness, high in moving capacity, high in operation precision, high in automation degree, large in motion range and the like; weighing and mass center measuring functions are achieved, precision abut-joint assembling of large thin-wall components is achieved, the large component abut-joint difficulty and potential safety hazards are greatly reduced, abut-joint efficiency and abut-joint precision are improved, abut-joint components are effectively protected, and the assembling quality needs are met.

Description

technical field [0001] The invention relates to a technology in the field of assembly and docking, in particular to a six-degree-of-freedom flexible positioning device for automatic docking and assembly of large thin-walled cylindrical components. Background technique [0002] At present, most of the assembly and docking of domestic large-scale thin-walled parts still rely on visual inspection and hand cranking. Usually, the two components are respectively placed on the bracket or the trailer platform, and there is a circle of corresponding hole pin matching structures on the butt ring surface of the two components. Push one part slowly close to the other part, observe and manually adjust the posture of the corresponding hole pin, and insert it after alignment. This method leads to low matching accuracy of the butt face pins, large assembly stress, affects fatigue strength, and low efficiency. Moreover, in actual work, the flexibility of the assembly equipment is poor, and...
