Abstract: A magnet chuck has a piston assembly including a tube shaped permanent magnet and a core yoke able to move on the interior of a cylinder tube. The permanent magnet is provided on the outer periphery of the core yoke, is magnetized in the radial direction, and a magnetic sensor is attached to the side surface of the cylinder tube.

Abstract: A magnetic chuck has a piston assembly that contains a cylindrical permanent magnet and a core yoke. The piston assembly is movable inside a cylinder tube. The permanent magnet is provided on the outer periphery of the core yoke and is magnetized in the radial direction.

Abstract: An air chuck includes a chuck unit including a pair of fingers that capable of being freely opened and closed, an operation unit that includes an operation mechanism, which opens and closes the pair of fingers, connection mechanisms for attaching the chuck unit to the operation unit such that the chuck unit is freely attachable and detachable to and from the operating unit, and a locking mechanism that locks the pair of fingers such that the pair of fingers are capable of being freely opened and closed when the chuck unit is attached to the operation unit and such that the pair of fingers are not able to be opened or closed when the chuck unit is detached from the operation unit.

Abstract: A chuck apparatus includes a first rotating shaft provided with a first gripping member, a second rotating shaft provided with a second gripping member, and a power transmission mechanism configured to convert reciprocating movement of a piston unit into rotational movement of the first rotating shaft and the second rotating shaft. The first rotating shaft and the second rotating shaft are arranged side by side in a direction of displacement of the piston unit.

Abstract: A magnet chuck includes a piston that is displaced inside a second sliding hole of a cylinder tube. One end surface of the piston abuts against a plate member when the piston reaches one displacement end point, whereas another end surface of the piston abuts against an entry member of a head cover when the piston reaches another displacement end point. At least one, and preferably both, of a first damper on the one end surface, and the second damper on the other end surface are disposed on the plate member.

Abstract: A magnet chuck includes, for example, four permanent magnets of a first permanent magnet through a fourth permanent magnet, serving as an attracting and retaining member for attracting and retaining a workpiece. In the first permanent magnet and the third permanent magnet, the magnetic polarity of a workpiece magnetic attracting surface facing the workpiece is of an N-polarity. On the other hand, in the second permanent magnet and the fourth permanent magnet, the magnetic polarity of a workpiece magnetic attracting surface is of an S-polarity. More specifically, in this case, combinations of the N-pole and the S-pole on the workpiece magnet attracting surface are formed in two pairs, and the N-pole and the S-pole, which are of different polarities, are adjacent to one another.

Abstract: A cylinder body includes a first guide surface made up from first guide grooves and a first bulging portion, wherein a slide table is displaceably supported on the first guide surface via a guide mechanism. Additionally, guide members of a guide block that constitutes the guide mechanism are inserted into and fixed within the first guide grooves. Further, the cylinder body is equipped with a second guide surface, which is formed with substantially the same shape as the first guide surface. In the event that the first guide surface is oriented upwardly and the slide table is installed thereon, the second guide surface acts as a mounting surface, whereas, in the event that the second guide surface is oriented upwardly and the slide table is installed thereon, the first guide surface acts as the mounting surface.

Abstract: A clamp apparatus is equipped with a cylinder mechanism having a piston. A driving force of the cylinder mechanism is transmitted to a clamp arm, which is retained on a housing through a block body and a link pin that make up a driving force transmitting mechanism, the clamp arm being rotated through a predetermined angle. The block body includes a rotatably supported roller. The block body is guided along an axial direction by displacement of the roller, while the roller is rotated along a guide member of the housing.

Abstract: A pair of jaw components 7a and 7b positioned on both sides of a casing 1 are attached to both the tips of a pair of parallel piston rods 6a and 6b which synchronously extend and contract in opposite directions by an action of an air pressure and the tips of a pair of guide rods 13a and 13b which synchronously extend and contract in opposite directions by a rack-and-pinion mechanism. By forming a magnetic scale 18 on a side face of one of the guide rods, 13b, the guide rod 13a is also used as a part of a dimension measuring mechanism. A sensor unit 20 for reading the magnetic scale 18 is attached to the casing 1.
