摘要： System for verifying the proper functioning of industrial screwdrivers placed on a test bench that has a plurality of hydraulic brakes (F), with which the screwdriver is associated, suitably controlled by a hydraulic circuit comprising one pump (P), which withdraws the fluid from a reservoir (T) and provides it to a pressure regulating valve (VP), which in turn provides it to the brakes. Each brake is provided with measuring transducers (TR), connected to an electronic driver board (SP). A computer (U) communicates with such card and comprises a suitable driving program stored thereon, the driving program, once an operator has selected the brake to be used for testing the screwdriver, being able to progressively increase the braking capacity of the brakes by adjusting the pressure, until reaching a complete stop of the electronic screwdriver.

摘要： Method to check the correct functioning of a tightening tool, such as an industrial screwdriver, placed on a test bench. Said bench includes a plurality of hydraulic brakes (F1-Fn), to which the instrument is associated, suitably controlled by a hydraulic circuit. Each brake is equipped with measurement transducers (TR) capable of measuring the torque exerted and the angle of rotation on this brake, connected to an electronic driver card (SP), which also controls the hydraulic circuit. The bench also includes an electronic processing unit (U) which communicates with the card and which includes an adequate driving program memorized on it capable of regulating the braking capacity of the brakes through the hydraulic circuit according to a predetermined braking torque / angle of rotation curve of the brakes. The method comprises the steps of acquiring one or more real tightening curves torque exerted / angle of rotation during one or more tightening performed for example with the tool to be tested, elaborating said real curve to make it compatible with the format of the curves that can be inserted in said test bench, supplying such one or more curves at the input to the test bench and in particular to one or more selected brakes (F1-Fn), performing a tightening with the tool on the selected brake.

摘要： Braking device inserted in a test bench (2) for checking the correct operation of industrial screwdrivers, wherein the braking simulates a tightening operation of such screwdriver, comprising a container body (1) on the top of which a coupling (11) protrudes, suitable for coupling with the head (3) of the screwdriver to be tested, said coupling (11) being connected, by means of a shaft (12), to a braking unit (13), an electronic torque and angle detector (14) of the shaft rotation (12). Such braking unit (13) comprises a plate (14), rotated by the screwdriver, which is braked by suitable friction surfaces (15) 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 (17).
