Abstract
Official abstract text for this publication.
A chuck apparatus includes a first rotating shaft provided with a first gripping member, a second rotating shaft provided with a second gripping member, and a power transmission mechanism configured to convert reciprocating movement of a piston unit into rotational movement of the first rotating shaft and the second rotating shaft. The first rotating shaft and the second rotating shaft are arranged side by side in a direction of displacement of the piston unit.
First claim
Opening claim text (preview).
What is claimed is: 1 . A chuck apparatus comprising: a body in which a cylinder hole is formed; a piston unit disposed in the cylinder hole, the piston unit being configured to move reciprocally under an action of a working fluid; a first rotating shaft and a second rotating shaft which are rotatably supported on the body, the first rotating shaft and the second rotating shaft being provided with gripping members configured to grip a workpiece; and a power transmission mechanism configured to convert reciprocating movement of the piston unit into rotational movement of the first rotating shaft and the second rotating shaft; wherein the first rotating shaft and the second rotating shaft are arranged side by side in a direction of displacement of the piston unit. 2 . The chuck apparatus according to claim 1 , wherein the power transmission mechanism comprises: a rack disposed on the piston unit; a first pinion disposed on the first rotating shaft, the first pinion being configured to be placed in meshing engagement with the rack; and a second pinion disposed on the second rotating shaft, the second pinion being configured to be placed in meshing engagement with the first pinion in a state of not being meshed with the rack. 3 . The chuck apparatus according to claim 2 , wherein the first pinion is formed to be longer than the second pinion. 4 . The chuck apparatus according to claim 1 , wherein: the piston unit comprises a pair of piston units disposed along an axial direction of the first rotating shaft; and the power transmission mechanism comprises: a first rack disposed on one of the piston units; a second rack disposed on another of the piston units; a first pinion disposed on the first rotating shaft, the first pinion being configured to be placed in meshing engagement with the first rack; and a second pinion disposed on the second rotating shaft, the second pinion being configured to be placed in meshing engagement with the second rack. 5 . The chuck apparatus according to claim 4 , wherein the first pinion and the second pinion are mutually meshed with each other. 6 . The chuck apparatus according to claim 4 , wherein the first pinion and the second pinion are not mutually meshed with each other.
