Abstract
The clamping apparatus for clamping work-pieces, is provided with optical detectors for sensing and/or controlling a movable member at the ends of a stroke. The working positions of the movable member are sensed by optical detectors removably supported and positionably housed in a front open casing fitted in the body of the apparatus. In the event the clamping apparatus being operated by a rotary actuator, use is made of an optical detector of rotary type to provide a set of control signals.
Claims7
Clamping apparatus for clamping a work-piece, of the type comprising:
- a box-shaped support head;
- a clamping member pivotally mounted on the support head to rotate between a first and a second position of a working stroke, to release respectively to lock said work-piece;
- an actuator having an axially movable pushing member operatively connected to the clamping member by a toggle-lever mechanism;
- and
- optical detection means for detecting at least a working position of the clamping member along said working stroke;
- wherein said optical detection means comprises:
- a front open casing longitudinally extending to clamping apparatus;
- at least one optical detector removably fitted into said front open casing, said optical detector having spaced apart light emitting and light receiving elements protruding from the casing;
- and
- means on said optical detector and casing for selectively positioning the optical detector into the casing of said optical detection means.
Clamping apparatus according to claim 7, wherein said rotary actuator is consisting in at least one electric motor.
