Low Costs Manufacturing Technology for Wing Installation and Exchange of a Certain Type of Aircraft
An analysis was conducted on the difficulty in installing the connecting pins between the wings and fuselage of a certain type of batch production aircraft,as well as the hole pitch exceeding the tolerance after the pin holes co hinged,and the damaged wings could not be installed interchangeably.By using the commonly used tooling design and tolerance alloca-tion technology in aircraft manufacturing,two sets of integrated tooling for reaming and inspection were designed,which had the function of individual reaming.We designed inspection tools for the insertion of the fuselage and wings,as well as the function of hole spacing inspection,which avoided the problem of excessive hole spacing caused by common hinges.By planning the process of reaming operations and designing specialized cutting tools,the idea of requiring multiple sets of fix-tures and gauges to ensure coordinated hole spacing was improved.The installation and exchange of wings for a certain type of aircraft were achieved.After batch trial production verification,this design method effectively solved the problem of in-stallation and exchange of wings and fuselage for a certain type of aircraft,improved production efficiency,and reduced pro-duction costs.At the same time,it also provided a reference for other production methods with similar structures.
