Abstract

The invention discloses six-degree-of-freedom positioning gesture adjusting equipment used for the automatic assembling of a large barrel-shaped thin-wall construction member in the technical field of assembling butt joint. The six-degree-of-freedom positioning gesture adjusting equipment comprises a base, six PSS (pair-sphere pair-sphere pair) branch chains and a dynamic adjusting platform with a construction member bracket, wherein the six PSS branch chains are arranged on the base; the dynamic adjusting platform is connected with one end of each PSS branch chain; a thin-wall construction member of which the gesture is to be adjusted is fixedly connected with the construction member bracket. According to the six-degree-of-freedom positioning gesture adjusting equipment, the arbitrary adjustment of the spatial position of the large barrel-shaped thin-wall construction member to be installed and bolt butt joint along the axial direction of the large barrel-shaped thin-wall construction member are realized so as to realize the precise butt joint assembling of the large barrel-shaped thin-wall construction member.

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 positioning and posture adjustment equipment for automatic assembly of large cylindrical thin-walled components. Background technique [0002] At present, the docking of large parts in domestic aircraft assembly mainly relies on tooling and process compensation to ensure the coordination between large parts. In particular, the two parts are placed on the bracket or trailer platform respectively. There is usually a circle of holes and connecting pins on the docking ring surface. Push one part slowly close to the other part, observe and adjust the connecting holes and pins, and then insert after alignment. This method makes the matching accuracy of the hole pins on the butt joint surface low, easy to generate stress, and has a great influence on the fatigue strength. Aiming at this problem, a posture-adjusting assembly equipment sui...
