Problems solved by technology

However, this technology lacks rotating joints, and the deviation of the attitude adjustment of the front and rear brackets may cause distortion and deformation of thin-walled parts; the attitude adjustment has too high requirements for the initial positioning of the parts to be assembled; the visual and manual attitude adjustment accuracy is poor and the efficiency is low, which cannot meet the requirements of modern production

Abstract

The invention discloses a co-location device for automatically butting and assembling large-sized thin-wall barrel-shaped members and belongs to the field of assembling butting technologies. The co-location device comprises at least two sets of location mechanisms fixedly connected with the large-sized thin-wall barrel-shaped members to be assembled respectively, wherein each location mechanism comprises a slide chassis, a transverse posture adjustment platform, a vertical posture adjustment platform and a rotary posture adjustment platform. The device has the advantages of high operation precision, high automation level, large bearing capacity, high response speed and wide motion range, and can be used for accurately butting and assembling the large-sized thin-wall barrel-shaped members.

Description

technical field [0001] The invention relates to a device in the technical field of assembly and docking, in particular to a six-degree-of-freedom cooperative positioning device for automatic docking and assembly of large thin-walled cylindrical components. Background technique [0002] At present, the assembly and docking of large thin-walled parts in China mainly relies on visual inspection and hand cranking to ensure the adjustment and coordination of parts. 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. Aiming at this problem, a six-d...
