Abstract
An output rod (20) of an electric clamping device includes: a tubular power transmission member (25) screw-connected to a decelerator (6); and an output rod main body (24) disposed radially inward of an inner peripheral surface of a cylindrical hole of the power transmission member (25) with a clearance between the output rod main body (24) and the inner peripheral surface. The output rod (20) further includes: a rotation preventing mechanism (26); a lock-side driving mechanism (27, 42), a release-side driving mechanism (28), and an output rod guide mechanism (29).
Claims8
An electric clamping device comprising:
- an output rod inserted in a housing so as to be movable in an axial direction toward a lock side and a release side;
- a motor attached to the housing;
- and
- a decelerator provided beside the output rod, the decelerator configured to transmit rotational motion of the motor to the output rod, wherein
- the output rod comprises:
- a tubular power transmission member screw-connected to the decelerator;
- an output rod main body disposed radially inward of an inner peripheral surface of a cylindrical hole of the power transmission member with a clearance between the output rod main body and the inner peripheral surface;
- a rotation preventing mechanism configured to prevent relative rotation between the output rod main body and the power transmission member;
- a lock-side driving mechanism configured to move the output rod main body toward the lock side via the power transmission member;
- a release-side driving mechanism configured to move the output rod main body toward the release side via the power transmission member;
- and
- an output rod guide mechanism configured to guide movement of the output rod main body while preventing co-rotation with the decelerator.
