Abstract

A mandrel installation device for a flexible marine propeller, including a workbench, a quick auxiliary centering and positioning device, a lifting device, a rotation locking device, a mandrel, a linear track and a control system, and the workbench is arranged on the ground and supported by four pillars , the upper part of the workbench is equipped with a fast auxiliary centering and positioning device, the propeller is placed on the upper part of the rapid auxiliary centering and positioning device, the mandrel is placed at the center hole of the propeller, the linear track is arranged at the bottom of the workbench and welded as a whole with the pillar of the workbench, and the upper part of the linear guide rail is The lifting device is arranged, and the rotating locking device is arranged on the upper part of the lifting device to install the nut and the taper fast. The invention solves the technical problem of difficult centering adjustment in the installation process of the large propeller mandrel, enables the propeller to accurately adjust the position, realizes the mandrel installation of propellers with different aperture sizes, and overcomes the safety and reliability problems of manual installation of large tonnage propellers .

Description

technical field [0001] The invention relates to the technical field of machinery manufacturing equipment, in particular to a mandrel shaft installation device for a flexible marine propeller. Background technique [0002] With the development of high-tech, global trade increases, the demand for large ships increases, and the size of marine propellers is getting larger and larger, which puts forward more requirements for its processing. CNC machining of propeller hubs and blade roots is carried out on special machine tools for propeller processing. Before, the mandrel needs to be installed in the center hole of the propeller, and the propeller is hoisted by the crane and installed on the machine table. [0003] At present, the installation of large-scale marine propeller mandrel mainly adopts the method of mechanical assistance and manual installation. One is horizontal installation. Using driving, the hoisting mandrel is placed horizontally on the support device, and the pro...
