The invention discloses an
optical fiber jumper wire stroking type
cutting device in a free suspension state, and the device comprises a blocking
assembly, a wire stroking
assembly, a cable guiding
assembly, a cable collecting assembly, and a
cutting assembly, and all the assemblies are disposed on a main installation plate in a layered manner. The cable guide assembly is provided with a guide rail, so that the cable slides under the action of gravity and is guided into the blocking assembly, and first point positioning of the head end of the cable is achieved. A flexible clamping jaw of the cable straightening assembly clamps the cable in a force-limiting half-clamping mode, so that the cable slowly slides relative to the clamping jaw under the action of
self weight and tensioning of the cable collecting assembly, and vertical straightening and
posture correction of the cable are achieved. The cable collecting assembly clamps a cable through a driving wheel and an elastic loading driven wheel to form stable tensioning, and supports intermittent inching and positioning maintaining. The
cutting assembly is matched with a
tungsten steel movable blade and a
tungsten steel fixed blade and slides and cuts in a sliding cutter groove in the direction perpendicular to the axis of the cable, and precise cutting of the cable in the tensioning state is achieved. According to the invention, the problem that the
pose of the freely
suspended cable is uncertain is solved through a cooperative mode of gravity introduction, blocking positioning, flexible straightening, tensioning keeping and sliding shearing, the cutting precision is improved, and automatic production expansion is supported.
