CLAMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2004/012902
Kind Code:
A1
Abstract:
A circular ring-like plug portion (21) is upwardly projected from a clamp pallet (2) and a circular ring-like shuttle member (23) is supported by the plug portion (21) so as to be movable up and down. A tapered inner peripheral face (12) engaging with a tapered outer peripheral face (28) of the shuttle member (28) is provided on the work pallet (3). A transmission member (29) is inserted in the upper part of a cylindrical hole (21a) of the plug portion (21), and a rod (31) is inserted in the lower part of the cylindrical hole (21a). When the rod (31) is driven downward for clamping, an output portion (36) of the rod (31) causes the work pallet (3) to move downward through an engagement ball (34) and forms a transmission gap (G) between a pressing portion (31a) at the upper end of the rod (31) and a pressure-receiving portion (29b) of the transmission member (29). When the rod (31) is driven upward for unclamping, the pressing portion (31a) presses the work pallet (3) upward through the transmission member (29).
