Abstract
A clamp device includes a support mechanism that supports a grip member when expanding the diameter thereof, a clamping hydraulic cylinder that can drive the grip member and a clamp rod axially forwards and backwards (up and down), and a main body member to which the grip member, the clamp rod, the support mechanism, and the clamping hydraulic cylinder are mounted, with the grip member, the clamp rod, and the support mechanism being positioned at one end portion of the body member, and with the common axis of the grip member and the clamp rod being offset from the axis of the clamping hydraulic cylinder in a direction orthogonal to the clamp rod.
Claims16
A clamp device having an annular grip member capable of expanding and contracting in a radial direction, of being inserted into a hole in a workpiece and of gripping an inner circumferential surface of the hole, and a clamp rod including a tapered shaft portion fitted into and engaged with the grip member, comprising:
- a support mechanism for supporting the grip member when a diameter of the grip member is expanded;
- a clamping fluid pressure cylinder capable of driving the grip member and the clamp rod forwards and backwards in the axial direction;
- and
- a main body member to which the grip member, the clamp rod, the support mechanism, and the clamping fluid pressure cylinder are installed;
- wherein the grip member, the clamp rod, and the support mechanism are positioned at one end portion of the main body member, with an axis of the grip member and the clamp rod being offset from an axis of the clamping fluid pressure cylinder in a direction orthogonal to the clamp rod.
