A high-precision automatic assembly and docking system for ship sections with multi-degree-of-freedom adjustment

Abstract

The invention discloses a multi-degree-of-freedom-adjustable high-precision automatic assembly and docking system for ship sections, which relates to the technical field of shipbuilding and automatic assembly, and includes a trolley module, a ground track module, a sensor measurement module and a ship section module; the trolley module Installed in the track chute of the ground track module; the sensor measurement module is arranged on the periphery of the ship section module; the moving ship section in the ship section module is installed on the trolley module. By arranging multiple four-degree-of-freedom trolleys for coordinated movement and combining measurement equipment for data fusion, the present invention can efficiently and flexibly adjust the position and attitude of the ship section to be closed. The system is a closed-loop system with real-time feedback of measurement data, high precision of motion adjustment, high degree of automation, and no need for manual verification and verification, which improves the work efficiency and quality of ship assembly. The overall device layout is simplified, and the operational safety of the mechanism is improved.

Description

technical field [0001] The invention relates to the field of shipbuilding and automatic assembly, in particular to a multi-degree-of-freedom adjustable high-precision automatic assembly and docking system for ship sections. Background technique [0002] The introduction of China's maritime power strategy has further promoted the development of the shipbuilding industry. With the development of shipbuilding technology, for large or even extra-large ships, the current mainstream construction adopts the segmented general shipbuilding method, that is, the hull is first constructed in segments, and then the ship segments are assembled by welding. The level of butt joint accuracy of the ship sections determines the quality of the hull welding, thus affecting the overall manufacturing level of the ship. [0003] The traditional method of closing the hull sections is to hang the section with a crane and keep it in the air, use a number of elastic screws or oil tops to adjust and po...

Problems solved by technology

[0007] In view of the above-mentioned defects in the prior art, the technical problems to be solved by the present invention are: 1. Based on the coordinated movement of multiple four-degree-of-freedom trolley modules, combined with peripheral sensory measurement data, the position and position of the section to be closed can be flexibly adjusted. Attitude, to ensure the accurate docking of the ship section; 2. A sensing and measuring device is installed on the periphery of the ship section module to monitor the position and attitude of the ship section in real time, and evaluate the quality of the docking surface. Greatly improved efficiency and safety
