Abstract

The invention discloses a threaded hole structure capable of accurately measuring the threaded connection state in real time, including a threaded hole structure, a strain measurement module, a transmission module and a single-chip microcomputer module; circle diameter, so that the thread major diameter of the threaded hole structure is greater than the thread major diameter of the corresponding standard threaded hole, so that a part of the threaded space is left inside the threaded hole structure, and the inner wall of the reserved threaded space is tightened Affixed to the strain sensor; the present invention can track and measure the stress and strain data of the threaded connection through the strain sensor closely attached to the inner wall of the threaded hole, so as to achieve the purpose of real-time monitoring of the thread fastening state and the goal of assisting the optimal arrangement of the screw space.

Description

technical field [0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to a threaded hole structure capable of real-time and precise measurement of the threaded connection state, which is applicable to real-time and autonomous monitoring of the threaded connection state, while judging the reliability of the threaded connection and assisting in decision-making Optimal spatial arrangement of threaded connections. Background technique [0002] Threaded connection is a very common connection method, and a large number of threaded connections are used in many large-scale equipment such as aircraft, aircraft, ships, etc. The current technical means are difficult to detect the connection status of the threaded connection in real time and autonomously, mainly relying on the manual inspection of the reliability of the threaded connection when the instrument is down. However, real-time and autonomous acquisition of thread stress and s...
