Abstract

A coordination location device for automatic butt joint assembly of large thin-wall cylindrical members comprises at least two groups of location mechanisms arranged on ground rails in a sliding mode and a member to be aligned with the location mechanisms. Each location mechanism comprises a rail car under-frame and a swinging platform mechanism, a transverse drive mechanism, a pitching platform mechanism and a member rotation mechanism which are arranged on the rail car under-frame successively. The swinging platform mechanisms, the transverse drive mechanisms, the pitching platform mechanism and the member rotation mechanisms of the location mechanisms are all in structures of drive moving pairs. At least one of the two member rotation mechanisms is a driving rotation pair, the others are driven rotation pairs, and at least one of the two rail car under-frames is a driving moving pair. By means of the device, arbitrary adjustment of to-be-assembled large thin-wall cylindrical member space postures is achieved, and accordingly, the accurate butt joint assembly of large thin-wall members is achieved.

Description

technical field [0001] The invention relates to equipment in the technical field of large component assembly, in particular to a coordinated butt joint process equipment for assembly of large thin-walled cylindrical components, which is composed of two sets of three or four sets of positioning mechanisms and has six degrees of freedom Posture adjustment and positioning function. Background technique [0002] At present, the assembly and docking of large thin-walled components in China mainly relies on process equipment and process compensation to ensure coordination between components. 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 accu...
