Title:
CLAMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/083625
Kind Code:
A1
Abstract:
A pair of lock members (22, 22) protruding further upward than a housing (1) and inserted into a hole in a workpiece are arranged so as to be capable of being pressed against both sides of the inner peripheral surface of the hole. The wedge surfaces (33) of a clamp rod (32) are engaged from above with the lock members (22). A drive means (D) drives the clamp rod (32) downward for clamping and drives the clamp rod (32) upward for unclamping. Recesses (50, 50) are formed in the outer peripheral surface of the clamp rod (32) at positions below the wedge surfaces (33, 33). The lock members (22, 22) are received in the recesses (50, 50) so that the lower portions of the inner peripheries of the lock members (22, 22) in an unclamp position can come into contact with each other.
