ABSTRACT

A cylinder type hydraulic clamp having a clamping mechanism is adapted to be
actuated by means of a hydraulic cylinder, and has a piston rod projected
through the cylinder body of the hydraulic cylinder and is equipped at its
leading end portion with the clamping means. The clamping means is arranged
concentrically with the piston rod and is adapted to be resiliently urged by
means of a contraction spring toward its contracted position to be pushed by
means of an expansion slant cam toward its expanded position. At the time of
the clamping actuation, when the clamping means is hydraulically actuated
toward the cylinder body through the piston and the piston rod, the clamping
means is first expanded diametrically by means of the expansion slant cam
against the resilient force of the contraction spring and then a member to be
clamped is fixedly pressed between the cylinder body and the clamping means
expanded as mentioned above.
