Patent number: 6718831Abstract: 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.Type: GrantFiled: September 20, 2002Date of Patent: April 13, 2004Assignee: BLM S.a.s. di L.

Patent number: 5886246Abstract: A test method for a screwer performs the steps of connecting the screwer to a rotatable attachment element, screwing down the screwer, measuring the attachment element speed, power-supplying an electric motor to bring it to a speed close to the measured speed, connecting the shaft of the electric motor to the attachment element, and causing the motor to follow a braking ramp while the torque transmitted from the screwer to the driving shaft is measured. A device in accordance with this method includes a rotatable attachment element to which the screwer to be tested is applied, and an electric motor connected to the attachment element through a releasable coupling connecting the motor to the attachment element on achievement of a motor speed close to that of the attachment element. The motor is controlled for following a braking ramp based on a predetermined law, while a transducer measures the transmitted torque between the attachment element and braking element.Type: GrantFiled: July 14, 1997Date of Patent: March 23, 1999Assignee: BLM S.a.s. di L.
