Claims

[Scope of utility model registration request]

An object can be held under pressure by moving a pair of opposing clamping plates toward and away from each other, and a lead screw shaft is attached to one of the clamping plates that can be slid on the bed. At the same time, a cylinder tube that can be rotated concentrically with the tube is provided at a predetermined position on the bed, and a cylinder tube that can rotate integrally with the tube and that can slightly slide in the axial direction is installed inside the cylinder tube. A threaded cylindrical body that is allowed to move and is screwed into the lead screw shaft is provided, and is slidable in the axial direction by fluid pressure at the inner part thereof, and by the sliding movement, the above-mentioned A holding part is formed by airtightly sealing a piston that can project a lead screw shaft together with a threaded cylinder, and the above-mentioned bed is fixed at a desired position on the base frame, and is fixed in one direction by a biasing member. A push rod is built into the casing so that its tip protrudes, and is moved against the elastic force of the biasing member by fluid pressure via the diaphragm. The fixing part is inserted into a relatively large through hole drilled in the frame, the tip of the push rod can be engaged with the bed, and the base frame is clamped and fixed at a desired position by the bed and casing. Features a clamping device.
