特徴とするねじ締め装置。A screw tightening drive electric screwdriver, its control unit,
It consists of a bit shaft driven by an electric screwdriver, a nut fixed to the bit shaft, and a switch mounted on a plate that moves relative to the bit shaft. The motor is stopped when the height reaches a certain level, but the load current applied to the motor is constantly monitored, and a normal screw tightening completion signal is issued only when the load current reaches a certain value immediately after the motor stops. Characteristic screw tightening device.
