Nockenantrieb und angetriebenes Hydraulikwerkzeug.

摘要

A motor driven hydraulic tool including a portable battery is preferably employable for a cable laying operation. To displace a movable die (48) toward and away from a stationary die (58), a piston (36) is driven by pressurized hydraulic oil fed from a hydraulic pump section (3). The hydraulic pump section (3) is operatively connected to a driving mechanism (2) including a motor (15) via a cam link mechanism (22). A plunger of the cam link mechanism (22) includes a ring-shaped fitting portion (26a) which has an eccentric shaft (19) fitted therein to rotate freely. The eccentric shaft (19) is made integral with the output of the driving mechanism (2).
