Abstract
Braking device inserted in a test bench () for checking the correct operation of industrial screwdrivers, wherein the braking simulates a tightening operation of such screwdriver, comprising a container body () on the top of which a coupling () protrudes, suitable for coupling with the head () of the screwdriver to be tested, said coupling () being connected, by means of a shaft (), to a braking unit (), an electronic torque and angle detector () of the shaft rotation (). Such braking unit () comprises a plate (), rotated by the screwdriver, which is braked by suitable friction surfaces () moved towards the plate by the movement of an actuator; the movement of such actuator is performed by means of at least one electronically controlled piezoelectric element ().
