Abstract: A clamp device has a gripping member which is expandable and contractible and is inserted into an aperture in a workpiece and grips the aperture, a clamp rod including a tapered shaft portion that fits into the gripping member, and a drive means for driving the clamp rod forwards and backwards. Provided is a support mechanism that supports the gripping member by fluid pressure when the gripping member is radially expanded, and a fluid pressure release means that releases the fluid pressure of the support mechanism after radial expansion of the gripping member when the clamp rod is driven by the drive means to perform clamping. The support mechanism has an annular pressure reception member that supports the gripping member, and a supporting fluid chamber that causes fluid pressure in the direction opposite to the clamping direction to be received on the annular pressure reception member.

Abstract: A clamping device 2 is provided with a hydraulic cylinder 7 for biasing a collet member 5 upward via a collet supporting member 6 and driving a pull rod 4 downward. A piston member 30 has a greater pressure receiving area than the collet supporting member 6 in the circular hydraulic chamber 31 of the hydraulic cylinder 7. Therefore, the hydraulic cylinder 7 can drive the pull rod 4 downward while the collet member 5 is biased upward. Meanwhile, the collet 5a of the collet member 5 is resiliently deformed in a diametrically expanding manner to engage in the vertical bore 1b of a workpiece 1 while slightly moving downward, ensuring a secure locking of the workpiece 1 to a workpiece receiving surface 3a.
