The finger pins are disposed movably in the longitudinal direction along guide holes of the body and connected to the movable fingers.

Abstract: A clamping device includes a body, a clamp arm and a drive mechanism that includes a displacement body displaced linearly, wherein the clamp arm is rotated based on the displacement of the displacement body. The displacement body includes a guide surface for guiding the rotation of the clamp arm, and also for controlling the rotation of the clamp arm while the clamp arm is in a clamping state. The clamping device further includes a push mechanism disposed at a position facing a lever arm and elastically pushing the displacement body toward the lever arm.

Abstract: A fluid pressure cylinder is provided with a cylinder tube having a sliding hole internally; a piston unit disposed along the sliding hole so as to be capable of moving back and forth, and a piston rod projected in the axial direction from the piston unit. The piston unit can shorten the axial dimension of a piston body by mounting a wear ring to an outer circumferential section of a ring-shaped magnet attached to an outer circumferential section of the piston body.

Abstract: A workpiece holding device includes a plurality of holding claws configured to hold a workpiece, and holding cylinders as claw opening/closing members configured to displace the holding claws in a direction closer to or away from a first workpiece. The holding cylinders are provided for the holding claws, respectively. Therefore, the plurality of holding claws can be opened/closed individually. The holding cylinders are held on a support disk as a holding member in a movable manner. That is, by moving the holding cylinders to arbitrary positions on the support disk, the holding cylinders are positioned fixedly.

Abstract: A workpiece gripping device includes a gripping member and a holding member. The gripping member includes a pair of extension parts that protrude from a base part and face each other with a space therebetween where the plate-shaped part of the workpiece can be inserted, and is deformable so that at least parts of the extension parts approach each other or are separated from each other. The holding member includes a slit for holding the gripping member slidably along a direction in the extension parts protrude, can make the extension parts approach each other by housing at least parts of the extension parts in the slit, and can make the extension parts be separated from each other by projecting at least parts of the extension parts from the slit.

Abstract: A clamp device is provided with a detection section which detects the pivotal position of a clamp arm. The detection section has: a cam section which is provided on a pivot shaft, includes a predetermined cam surface, and is formed so that the radial distance from the center of the pivot shaft to the cam surface varies circumferentially; and a proximity sensor which detects the position of the cam surface which varies as the pivot shaft pivots.

Abstract: A clamp device is equipped with a clamp body, a piston rod, a link mechanism, a detection mechanism for detecting a state of rotary motion of a clamp arm, and a determination unit for determining whether a state of clamping exists. The detection mechanism includes a first proximity sensor, and a knuckle joint having a first sloped surface. The determination unit, on the basis of a comparison of an output signal from the first proximity sensor to a clamp threshold value, determines whether a state of clamping exists, and on the basis of a comparison to a clamping force generation threshold value, determines whether a state of generation of clamping force exists.

Abstract: The present invention relates to a clamp device. The clamp device is provided with a driving force transmission mechanism, which transmits driving force from a drive unit to clamp arms. The driving force transmission mechanism converts the rectilinear movement of a piston rod of the drive unit into: a first operation, in which the clamp arms rotate while moving in directions toward or away from each other; and a second operation, in which the clamp arms move in parallel in directions toward or away from each other with gripping surfaces in a mutually parallel state.

Abstract: A clamp apparatus includes a support body that projects in a sideways direction of a body, together with a clamp arm, which is disposed rotatably in facing relation to the support body. On the support body, a support member, which extends in a horizontal direction, is disposed detachably with respect to a coupling hole of the body, whereas a connecting body, which interconnects a pair of arm members, is disposed detachably on an end of the clamp arm. A clamp release mechanism, which releases a clamped state when the clamp arm is locked, is disposed in the body, and is configured to press a joint of a driving force transmission mechanism that is accommodated in the body toward the side of a drive unit.
