Integrated manufacturing method and system for frame structure of aircraft hangar door or aircraft maintenance dock

Abstract

The invention provides an integrated manufacturing method and system for a frame structure of an aircraft hangar door or an aircraft maintenance dock. The integrated manufacturing method comprises the steps that profiles are placed on a production line; angle steel or channel steel or H-shaped steel is cut through the full-automatic cutting production line, and the profiles are automatically measured and cut off through the full-automatic cutting production line according to set lengths; special-shaped holes or round holes or threaded holes are machined in set positions of the angle steel or the channel steel or the H-shaped steel through a drilling production line; the machined angle steel or the machined channel steel or the machined H-shaped steel is subjected to surface treatment, packaged and conveyed to a mounting field; and on the mounting field, the angle steel or the channel steel or the H-shaped steel is spliced and connected through bolts, and thus the frame structure of the aircraft hangar door or the aircraft maintenance dock is formed. According to the integrated manufacturing method and system, the automatic production line is used for machining the profiles, so that the machining accuracy is improved, labor is saved, and the machining efficiency is improved; and welding is replaced by bolted assembling, so that field assembling is facilitated, and the assembling efficiency and the assembling accuracy are greatly improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing hangar doors or aircraft maintenance docks, in particular to an integrated manufacturing method and system for hangar doors or aircraft maintenance dock frame structures. Background technique [0002] Both the hangar door and the aircraft maintenance dock are combined by a variety of section steels, and the section steels are connected by welding. If the welding is completed directly in the factory area, the finished product of the entire hangar door or aircraft maintenance dock is too large to be transported. The existing technology is to transport the semi-finished products of section steel to the site, and then perform welding on site, so as to connect the section steel to form a complete hangar door or aircraft maintenance dock. Due to the large size of the hangar door or the aircraft maintenance dock, there are many connection nodes, and there are many positions that need to be welded. ...

AI Technical Summary

Problems solved by technology

Due to the large size of the hangar door or the aircraft maintenance dock, there are many connection nodes, and there are many positions that need to be welded. The welding workload is large, and the distribution of nodes is irregular. Manual welding is required, and automation cannot be realized. The work efficiency is low, and the accuracy of manual operation cannot be controlled. , leading to poor welding effect and low product quality
