Abstract
A pair of gripping sections performs opening and closing operations along a base member through displacement of a piston by means of a pressure fluid supplied to a chuck body. A pair of fingers, which constitute the gripping sections, is openable and closable in directions perpendicular to opening/closing directions of the gripping sections, by means of a driving force supplied from a driving section. The gripping sections are positioned with respect to a workpiece by actuating the pair of fingers to perform the opening/closing operation. Thereafter, by supplying the pressure fluid, the workpiece is gripped at a desired gripping position by means of the gripping sections.
Claims9
A chuck apparatus for gripping a workpiece by means of an openable/closable gripping mechanism, said chuck apparatus comprising:
- a body having a pair of ports for supplying a pressure fluid, said body including a piston installed internally therein, which is displaceable in an axial direction under action of said pressure fluid supplied through said ports;
- a driving section connected to said body and which is driven and rotated by an electric signal;
- and
- a gripping mechanism having a pair of first gripping sections and a pair of second gripping sections, said pair of first gripping sections being connected to said piston and being openable and closable under a displacement action of said piston, and said pair of second gripping sections being openable and closable under a driving action of said driving section so as to be opened and closed in directions perpendicular to opening and closing directions of said first gripping sections.
A chuck apparatus for gripping a workpiece by means of an openable/closable gripping mechanism, said chuck apparatus comprising:
- a body;
- a first driving section connected to said body and which is driven and rotated by an electric signal;
- and
- a gripping mechanism having a pair of first gripping sections and a pair of second gripping sections, said pair of first gripping sections being openable and closable by a driving force provided by said first driving section, and said pair of second gripping sections being openable and closable under a driving action of a second driving section distinct from said first driving section so as to be opened and closed in directions perpendicular to opening and closing directions of said first gripping sections.
