Threaded fastener connection qualification detection method, device, equipment and medium

The embodiment of the invention provides a threaded fastener connection qualification detection method and device, equipment and a medium. The threaded fastener connection qualification detection method comprises the following steps: acquiring operation time sequence characteristic data when an electric wrench tightens a threaded fastener on a main body structural member; judging whether the operation time sequence characteristic data is matched with qualified time sequence characteristic data of a corresponding type or not; and under the condition that the operation characteristic data is matched with the qualified time sequence characteristic data, it is judged that installation of the threaded fastener on the main body structural part is qualified. The fastening result of the threaded fastener is a gradually accumulated result in the tightening operation process, and the operation time sequence characteristic data can reflect whether the thread in the threaded fastener has defects or not, whether the threa
