Abstract
The invention relates to a thread structure component parameter 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 parameter measuring device, a thread structure is arranged on the upper portion of a body, a moving rod is arranged in the body, a magnet is arranged at the top end of the moving rod and stretches out of the body, the bottom end of the moving rod is connected with one end of a lever, the other end of the lever is connected with the bottom end of a movable pressure lever, the top end of the movable pressure lever is connected with a metal plate, a strain resistor disc is bonded to the metal plate, and the leading-out measuring wire of the strain resistor disc is led out of the body. According to the thread structure component parameter measuring device, a mandril is provided with a magnetic head to directly press the metal surface of a nut structure or a structural component with threads, the lever can press the strain resistor disc to generate curving until the strain resistor disc changes when the surface moves upwards or downwards, and the thread structure component parameter measuring device has the advantage of being high in measuring accuracy. Meanwhile, the measurement sealing performance of the strain resistor disc is good, and the application range is wide.
Description
Technical field
The present invention relates to a kind of measurement mechanism, relate in particular to a kind of helicitic texture component parameter measurement mechanism, be widely used in the indirect measurement of the measurement of bolt group degree of tightness, the measurement of bolt group textural association part snap-in force, nut or helicitic texture part shift motion amount etc.
Background technology
The stroke measuring device research that is applied at present the bolt group structural member of the scene use of electric power charging equipment belongs to blank field at home and abroad, the stroke measurment technology of most bolt group structural member is only applied to the experimental facilities of the travel parameters collection in laboratory, is not applicable to the stroke measuring device of power equipment GB bolt group structural member at present.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of helicitic texture component parameter measurement mechanism is provided, solved the problem of the stroke measuring device that is not applicable to power equipment GB bolt group structural member in prior art.
