Problems solved by technology

[0002] At present, tightening machines are generally used to tighten bolts. After the tightening machine has been used for a period of time, in order to ensure the tightening accuracy, it is usually necessary to re-measure and calibrate the tightening torque of the tightening machine. Usually, the traditional torque measurement patch is used, which needs to be connected When the wire is out, it is easy to cause the wire to be entangled during measurement, and the operation can only be performed when the tightening shaft is idling, and the true value of the torque in the working state cannot be measured, and the operation is inconvenient

Abstract

The invention provides an axial rotary type dynamic torque measurement calibrator. The calibrator comprises a conversion sleeve, a main casing, a liquid crystal display (LCD) screen, an indicating lamp, a gaging spindle, a sleeve, a sensor, a circuit and a battery, wherein a measurement meter can be arranged between a tightening shaft and a tightening sleeve, the actual torque value under a working state is detected when a tightening machine tightens a bolt, and the measurement meter does not have an outer lead wire, so no winding phenomenon is generated in the measuring process, and peak value maintenance and dynamic display modes are realized. The axial rotary type dynamic torque measurement calibrator has the advantages of simple structure and high accuracy of measurement calibration, and is convenient in operation.

Description

technical field [0001] The invention relates to the field of dynamic torque measuring and calibrating instruments, in particular to a shaft-type rotary dynamic torque measuring and calibrating instrument with simple structure, convenient operation and high measuring and calibrating precision. Background technique [0002] At present, tightening machines are generally used to tighten bolts. After the tightening machine has been used for a period of time, in order to ensure the tightening accuracy, it is usually necessary to re-measure and calibrate the tightening torque of the tightening machine. Usually, the traditional torque measurement patch is used, which needs to be connected When the wire is drawn out, it is easy to cause the wire to be entangled during measurement, and the operation can only be performed when the tightening shaft is idling, and the true value of the torque in the working state cannot be measured, and the operation is inconvenient.
