Title:
CLAMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/008210
Kind Code:
A1
Abstract:
A clamp device (C) has a cylindrical clamp body (1), a grip member (3) capable of being inserted into an insertion hole (11a) at the tip portion of the cylindrical clamp body (1), expanding outwards, and gripping the inner circumference surface of a hole (H) of a workpiece (W), a clamp rod (4) which, engaged with said grip member (3), extends in the vertical direction, and a forwards/backwards driving mechanism (5) capable of driving the clamp rod (4) forwards and backwards. Said clamp device is also provided with a seating surface (14) on which a workpiece formed at the tip of the cylindrical clamp body (1) sits, a case member (2) supporting the cylindrical clamp body (1) so as to allow movement forwards and backwards, a raising/lowering driving mechanism (7) capable of raising and lowering in a direction parallel with the shaft center of the clamp rod (4) the cylindrical clamp body (1) relative to the case member (2), and a lock mechanism (9) having a cylindrical member (91) into which the cylindrical clamp body (1) can be slidably inserted and which is supported by the case member (2), and capable of locking the outer circumferential surface of the cylindrical clamp body (1) by elastically deforming the cylindrical member (91) towards the side with the reduced diameter.
