    摘要: A coupling structure for a piston used in a fluid-pressure cylinder. The piston in the fluid-pressure cylinder includes a piston hole that runs through a central part of the piston in an axial direction thereof. One end of a piston rod and a coupling body coupled to the one end are inserted into the piston hole. The coupling body includes: a main part that contacts the one end of the piston rod; and an angled part formed around the main part and inclined at a prescribed angle with respect thereto. When the coupling body is subjected to pressure inside the piston hole, the diameter of the coupling body increases and a pointed edge of the angled part engages with an inner surface of the piston hole such that the coupling body couples the piston and the piston rod.

    摘要: A linear actuator includes a cylinder main body. With respect to the cylinder main body, a slide table is disposed for reciprocal displacement through a guide mechanism, which is disposed on the cylinder main body. A stopper mechanism having a stopper bolt is disposed on one end of the slide table centrally in a widthwise direction perpendicular to the longitudinal direction of the slide table. In addition, when the slide table is displaced along the cylinder main body, an end of the stopper bolt comes into abutment with an end of a cover of the guide mechanism, whereupon the slide table becomes engaged therewith and movement of the slide table is stopped.

    摘要: A linear actuator includes a guide block constituting a guide mechanism. In the guide block, a pair of installation grooves are formed in a lower surface facing toward a cylinder main body. Ball circulation members having therein ball circulation holes are installed respectively in the installation grooves. Additionally, ball circulation passages through which balls circulate are provided. The ball circulation passages are made up from roll-reversing sections disposed on opposite ends of the ball circulation members, the ball circulation holes, second ball guide grooves formed in both side surfaces of the guide block, and first ball guide grooves of the slide table.

    摘要: A linear actuator includes a cylinder main body, which is provided at one end thereof with a lock mechanism capable of restricting displacement of a slide table. The lock mechanism is equipped with a lock plate and a sub-piston. The lock plate is rotatable toward a side of the slide table by an elastic force of a spring, inserted into an insertion groove, and restricts displacement of the slide table. The sub-piston is displaced by a pressure fluid supplied to a supply port, and releases a displacement restricted state of the slide table by the lock plate.

    摘要: A linear actuator includes a guide mechanism and a retainer. On a guide block of the guide mechanism, a pair of ball-circulating grooves is formed on the lower surface that faces a cylinder body. Multiple balls are loaded in the ball-circulating grooves. Paired cover blocks are respectively mounted on the two ends of the guide block. The retainer has the form of paired ball clips, which are formed as arms to engage with the cover blocks when the clips are inserted in the ball-circulating grooves to hold the balls. Paired cover plates are respectively mounted on the end faces of the cover blocks, and arm-shaped cover clips are mounted so as to hold the cover plates. The cover plates, the cover blocks, and the guide block are thereby integrally linked.
