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.
Screwer test bench comprising a coupling connected to a braking unit and designed for coupling with the head of a screwer, and a sensor unit detecting mechanical magnitudes transmitted between the coupling and the braking unit and the braking unit comprising a friction brake with braking surfaces which upon operation of he brake are thrust upon command one against the other in a braking direction, the brake has a movable thrust member of said braking surfaces in said braking direction which is constrained against rotation around the brake axis by means of an inextensible wall with configuration deformable in said braking direction.
