Tightening tool equipped with a tightening quality control device

Abstract

Tightening tool comprising a body (11), containing control circuits and an electronic processing unit having at one end a handle (12) for gripping by an operator performing the tightening, and at the other end an arm (13). Such arm at its free end comprises a seat (16) into which a plurality of inserts can alternatively be inserted, suitable for engaging the tool with a corresponding type and/or size of a mechanical member on which the tool is intended to act to perform a tightening operation. Sensor means are provided on said arm suitable for detecting tightening conditions exerted on said mechanical member. Such sensor means comprise at least one inertial measurement unit (IMU) connected to such electronic processing unit, capable of detecting tool rotations about the three cartesian axes (x, y and z) and direct accelerations along such axes.
