Abstract: A clamping device for fixing a die on the setting surface of a lateral injection molding machine comprises a clamp main body, plural clamping hydraulic cylinders installed in the output portion at the front end portion of the clamp main body, and a guide mechanism for guiding the clamp main body movably only in the longitudinal direction without separate from the setting surface, in which the clamp main body can be freely changed over in position with respect to the setting surface in the released state, so that it may not be dislocated from the setting surface. The lower base portion of the clamp main body can be divided as a base member to be fixed on the setting surface.

Abstract: A clamping device for clamping a work piece to be machined by a machine tool on a base surface of a table of the machine tool or a work pallet for fixing a work piece, comprises at least a clamp main body, a reaction support provided at the rear portion of the clamp main body, an input member disposed in front of the reaction support on the clamp main body with a gap therebetween, an output member arranged in front of the input member and having an output portion for clamping the work piece at the front end, a guide mechanism for slidably guiding the output member in a longitudinal direction directed back and forth, a driving mechanism for driving the input member toward the clamp main body, and a wedge type converting mechanism for converting a driving force supplied to the input member from the driving mechanism into a clamping force for driving the output member.

Abstract: A clamp device drive apparatus for driving a clamp device engaged with a T-shaped groove slidably between a clamping position and an unclamping position, comprises a push-pull chain connected to a clamp device, a vertical housing for containing the chain, guide members for turning a running course of the chain, a sprocket engaged with the chain, and a cylinder drive type motor for driving the sprocket to rotate, and the motor is constituted to drive the sprocket with a double acting fluid cylinder or a pair of single acting fluid cylinder, through ball screw mechanism for converting driving force into driving torque.
