Abstract
The invention relates to a thread structure component measuring device which is widely applied to bolt set tightness degree measurement, bolt set structure combined part pressing force measurement and nut or thread structure part move stroke indirect measurement. According to the structure of the thread structure component measuring device, a thread structure is arranged on the upper portion of a body, a fixing groove is formed in the body, a sliding resistor is arranged in the fixing groove, and a sliding resistor leading-out wire is led out of the body. The top end of a telescopic rod stretches out of the body, the bottom end of the telescopic rod is connected with one end of the spring, and the other end of the spring is fixed to the bottom of the body. One end of a resistor sliding piece is in sliding connection with the sliding resistor, the other end of the resistor sliding piece is fixedly connected with the telescopic rod, and a leading-out wire of the resistor sliding piece is led out of the body. According to the thread structure component measuring device, due to the fact that the changes of resistance values can be recorded by measuring the leading-out wire of the sliding resistor and the leading-out wire of the resistor sliding piece, the move stroke of a nut structure part or a structural component with threads is known indirectly, measurement is accurate, operation is convenient, and the application range is wide.
