Electromechanical assembly tool with torque motor

Abstract

An electromechanical assembly tool (10) including a housing (12), a torque motor (16), a planetary roller screw (18) and a linearly movable pincer head wedge (30), wherein the torque motor (16) includes a stator (38) and a rotor (40), wherein the stator (38) is mounted in the housing (12) and the rotor (40) is clamped and fixed on the rotatable but axially fixed spindle (32) of the planetary roller screw (18). The planetary roller screw (18) includes a spindle (32), a nut (34) and plural planetary rollers (36), wherein the nut (34) held in the housing (12) in an axially moveable but non-rotatable manner and axially connected to the pincer head wedge (30) such that the rotary movement of the motor rotor (40) is converted into a linear movement of the nut (34) and of the pincer head wedge (30). The rotor (40) of the torque motor (16) is directly mounted on the rotatable spindle (32) of the planetary roller screw (18).
