DISPOSITIF DE CONTRÔLE DE FORCE LORS DE LA FIXATION D'UN COLLIER DE SERRAGE

摘要

The invention relates to a tool for fixing a fastening club, which tool has a pair of levers pivotable about parallel axes (8), which at the ends thereof bear tongs jaws (9) that can be moved toward each other and act on the clamp. To monitor the forces occurring during the locking of fastener and clamping band of the fastening clamp, use is made of a device that has a housing (11) fixed with respect to the tool and a pair of force transmission limbs (15). Each force transmission limb (15) is attached elastically to the housing (11) at one end, and the other end bears a contact surface (17) for a force sensor (18) fitted to the housing and, between the ends of the force transmission limb, has a hole (20), in which the shaft (8) of the relevant to lever is supported. A force/time or force/travel curve obtained from the sensor signals is used as a measure of the quality of the locking between fastener and clamping band.
