HYDRAULIC BRAKING DEVICE TO BE PLACED ON TEST BENCHES FOR INDUSTRIAL SCREWDRIVERS AND RELEVANT TEST BENCH

摘要

Hydraulic braking device for testing industrial screwdrivers, said braking device being arranged on a braking simulation bench, said braking device being controlled by an actuator and by a hydraulic control circuit which supplies pressure to the device on the basis of the indications of an electronic elaboration unit (U) of said bench. Such a braking device is provided with coupling means (A) for said screwdriver to be subjected to test and measurement transducers (TR) controlled by said processing unit, suitable for measuring the torque exerted by the screwdriver and the rotation angle, and such a device comprises a memory which can be read and/or written by the bench electronic elaboration unit.
