Abstract
A screwer test bench includes a coupling designed for coupling with the head of a screwer. The coupling is connected to a braking unit through a sensor unit for detection of mechanical magnitudes transmitted between the coupling and the braking unit. The braking unit includes a cap connected to the coupling and a movable member thrust on command in the brake operation direction. The movable member is constrained against rotation around the brake axis by an inextensible wall with a configuration deformable in the braking direction. Advantageously the wall is in the form of a bellows into which is fed pressurized fluid to bring about its elongation and operate the brake.
