Abstract
The present invention relates to a linear actuator. A slide table of the linear actuator includes a table main body and an end plate connected to another end of the table main body. On a base portion of the table main body, four workpiece retaining holes are formed, and fitting seats are disposed respectively about the workpiece retaining holes on radial outer sides thereof. The fitting seats are formed at the same time that the table main body is formed by press molding.
Claims10
A linear actuator in which, by introduction of a pressure fluid from fluid inlet and outlet ports, a slide table is made to move reciprocally along an axial direction of a cylinder main body, comprising:
- the cylinder main body, which communicates with the inlet and outlet ports and having a cylinder chamber into which the pressure fluid is introduced;
- the slide table having a base portion disposed substantially parallel to the cylinder main body and a mounting portion that projects with respect to the base portion for mounting an object to be transported thereon, the slide table moving reciprocally along the axial direction of the cylinder main body;
- and
- a cylinder mechanism having a piston that is arranged for sliding movement along the cylinder chamber, wherein the slide table is made to move reciprocally upon displacement of the piston,
- wherein the slide table includes a positioning hole therein into which a positioning member that is installed in the object to be transported is respectively inserted, the positioning hole having a projection projecting radially inward from an inner circumferential surface of the positioning hole to prevent the positioning member from dropping out.
