Automatic grouping method and system for ship pipe fitting family manufacturing

Abstract

The invention provides an automatic grouping method and system for ship pipe fitting family manufacturing, and the method comprises the steps: determining to-be-grouped pipe sections according to a production plan, a production takt and a raw material inventory condition; the pipe section is disassembled into a large assembly, a middle assembly and a small assembly according to the geometrical characteristics and the machining method of the pipe section; taking the assemblage as a unit, and classifying the assemblage into groups according to the specification of the pipe and the machining process of the assemblage; and outputting an assembly processing list and a pipe section assembly three-dimensional model of each pipe production line. The method has the beneficial effects that the pipesection machining grouping technology is optimized, the pipe grouping rate is increased, the production batch is enlarged, the pipe section manufacturing production efficiency is improved, the timeliness and integrity of tray distribution are ensured according to the production plan of trays and the raw material inventory situation, and the problems that an existing pipe fitting family grouping technology is low in grouping rate, low in automatic welding application rate and high in production cost, and the integrity and timeliness of the pipe section tray are not high are solved.

Description

Technical field

[0001] The present invention relates to the field of design and manufacturing techniques of ship tube, and more particularly to automatic grouping methods and systems for shipbuilding finishes manufacturing. Background technique

[0002] At present, the international competitiveness of large-scale ship assembly plants in China has increased, and the number of ships, the number of ships increases. There is a large gap between the output of the marine pipe section. There is a large gap between the capacity and actual needs of the pipe section processing workshop. Currently, it is mainly relying primarily on increasing personal input and extended Manufacturing hours make up for vacancies. The field of pipe section is urgent to improve the processing efficiency of pipe sections to meet the production needs.

[0003] Many domestic tube processing workshops have been applied in group technologies, but the minimum unit of group is a tube section, and the pipe family is i...
