Abstract
A fluid pressure cylinder includes a displacement block, which is displaceable on another end side of a body. A second connector of a piston rod that constitutes a cylinder unit is screw-engaged via a second cylinder hole with the displacement block. On the other hand, an end of a suction rod to which a negative pressure fluid is supplied is inserted through a cover member. In addition, by inserting a tool into a tool groove, which is formed on an end of the second connector and rotating the tool in a predetermined direction, the displacement block can be moved with respect to the piston rod in directions to approach and separate away from the body. Stated otherwise, a relative position of the displacement block with respect to the body can be adjusted.
Claims6
A fluid pressure cylinder comprising:
- a body including a cylinder chamber in interior thereof to which a driving fluid is supplied;
- a cylinder unit including a piston disposed in the body and which is displaceable in the cylinder chamber, and a piston rod connected to the piston;
- a supply rod disposed displaceably and substantially in parallel with the piston rod in the body, and including a flow path to which a workpiece retaining fluid is supplied to interior thereof, with a retaining member being installed on a distal end of the supply rod, the retaining member being configured to retain a workpiece and to communicate with the flow path;
- a displacement block connected respectively to ends of the supply rod and the piston rod, and which is displaced under a displacement action of the piston;
- and
- a position adjustment mechanism that is configured to adjust a relative position of the displacement block with respect to the body,
- wherein the position adjustment mechanism is disposed on the end of the piston rod.
