Abstract
The clamp comprises a clamp unit having a pair of clamping plates and clamping plate drive unit. A fixing unit fixes the clamping unit to an arbitrary position on a base frame. The clamping unit has a sub base to which one clamping plate and drive unit for driving the other plate are fixed. The drive unit has a leadscrew fixed at its one end to the other plate, and an outer cylindrical member rotatably provided on the sub base and holding the other end of the leadscrew. An inner cylindrical member and a piston are provided in the bore of the outer member. The inner member is threadably fitted over the other end of the leadscrew, and is rotated integrally with the outer one so as to move the leadscrew. The outer member is connected to a pressurised fluid supply for supplying fluid to the bore of the outer member to move the piston. This movement causes the inner member to move outwardly in the longitudinal direction in the bore of the outer member, and the leadscrew, together with the other plate, moves to approach one plate.
