Jacking parallel move swivelling mechanism

Abstract

The invention relates to a jacking translation rotating device used for jacking giant workpieces. A gliding plate body is fixedly mounted on the gliding underframe; a gliding bearing arranged on the gliding plate body is glidingly connected with the gliding plate body; a translation oil cylinder is fixedly arranged on the gliding underframe; a transversely protruded piston rod is glidingly and hermetically connected with the body of the translation oil cylinder; a baffle plate is fixed on the piston rod; the baffle plate divides the inner cavity of the oil cylinder into two independent oil inlet cavities; the fridge of the baffle plate is glidingly and hermetically connected with the inner wall of the translation oil cylinder; a jacking oil cylinder is fixed on the body of the gliding oilcylinder; a mounting bearing is fixed on the outside of the gliding bearing; a rotating support arranged on the mounting bearing is rotationally connected with a rotating support frame; a driven gearis fixed on a servomotor; and two ends of the piston rod are fixedly connected on the rotating support frame. The invention enables the jacking and the translation in a closed-loop controlled state, supports the workpiece with a plurality of points, and realizes sensitive adjustment of six degree of freedom.

Description

technical field [0001] The invention relates to a jacking, translation and turning device for jacking up a huge workpiece. Background technique [0002] The manufacture of modern large-scale ships generally adopts the method of large-scale segmentation and later overall splicing. For this reason, a set of tools for fine-tuning large-scale segmentation devices and precise alignment assembly is required. Many companies produce hydraulic adjustment systems for hydraulic jacking and translation for this need. Although these jacking adjustment systems have solved the jacking problem of heavy loads, since the hull segments are getting larger and larger, multiple points (20 points or more than 30 points) are required to jack up and adjust a super-large segment at the same time, how to make multiple Dots moving in unison became a difficult problem. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide...
