Title:
インパクト回転工具、トルク算出方法及びプログラム
Document Type and Number:
Japanese Patent JP7403067
Kind Code:
B2
Abstract:
An object of the present disclosure is to accurately calculate a tightening torque when a fastener component is tightened. An impact rotary tool (1) includes a drive source, an impact force generator, an output shaft, a torque measuring unit, and a torque calculator (141). The impact force generator is configured to generate impact force in pulse form from power of the drive source. The output shaft is configured to transmit the impact force to a tip tool. The torque measuring unit (11) is configured to measure a torque applied to the output shaft. The torque calculator (141) is configured to, when a torque waveform of the torque measured by the torque measuring unit during one impact includes a plurality of peak values, calculates the tightening torque in accordance with a largest peak value of one or more second or subsequent peak values.
