Automatic docking and attitude adjustment positioning device for large cylindrical components with coordinated movement function

Abstract

An automatic butting and posture-adjusting positioning device used for large cylindrical components and with a coordinated motion function comprises at least two sets of positioning mechanisms which are fixedly connected with the to-be-assembled large cylindrical components through embracing hoops. Each positioning mechanism comprises a chassis, a transversal posture-adjusting platform serving asa y-direction moving pair, a rotating posture-adjusting platform serving as a passive rotating pair around a z-axis, a vertical lifting platform serving as a z-direction moving pair and a bracket usedfor supporting the embracing hoops, wherein the transversal posture-adjusting platform, the rotating posture-adjusting platform, the vertical lifting platform and the bracket are arranged on the chassis; and the rotating posture-adjusting platform is connected with the transversal posture-adjusting platform and a vertical lifting device, and the bracket and the embracing hoops are fixedly connected. The automatic butting and posture-adjusting positioning device has the advantages that the coordinated motion ability is high, the posture-adjusting range is wide, the butting precision is high, the overturn-preventing ability is achieved, and safety performance is high; and six-degree-of-freedom posture adjusting and precise butting and assembling of the large cylindrical components can be achieved.

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 cooperative positioning device with a coordinated movement function for automatic docking and assembly of large cylindrical components. Background technique [0002] In the butt assembly of some large cylindrical components, it is usually necessary to adjust the attitude and positioning of the components with six degrees of freedom to ensure that the positioning pins and positioning holes on the docking plane can be accurately matched. At present, the butt joint assembly of large-scale cylindrical components in China mainly relies on manual adjustment, which has poor precision and low efficiency. At the same time, due to the limitation of the degree of freedom of the positioning device, the fixation of the cylindrical member is mainly in the form of an arc-shaped hoop, which relies on the gravity of the cylindrical member to ensure conta...
