Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aircraft manufacturing, in particular to a full-automatic closing system and method of self-locking nuts for aircraft. BACKGROUND

[0002] The principle of preventing self-loosening of the self-locking nut during use is to close the end of the self-locking nut cylinder, deform the thread hole at the closed position of the nut, and generate interference fit when the nut is screwed into the closed position of the nut, thereby playing the role of anti-loosening and anti-vibration.

[0003] As a kind of anti-loosening nut, the self-locking nut is widely used in the field of aviation, but in the related manufacturing industry, the production technology and equipment of nut closing are relatively backward. At present, the closing is mostly carried out by punch combined with closing die. The closing die is installed on the punch, and the worker manually holds the hexagonal nut cylinder end to the lower die of the closing die for positioning and supporting. After the punch drives the upper die to stamp the hexagonal nut cylinder end, the worker holds the hexagonal nut away from the punch.

[0004] This process has great safety hazards, which is extremely detrimental to the personal safety of workers on site, and the process can only close the self-locking nuts one by one, which is extremely low in efficiency. At present, some improvements are made on this process to solve the safety hazards on site, but the problem of manual intervention cannot be completely solved, and the production efficiency cannot be maximized.
