Abstract
A linear positioning apparatus has a positioning actuator assembly including a cylinder and movable piston to be used for moving a workpiece or a moveable worktable along a rectilinear path or thrust axis. The apparatus includes at least one stop member adjustably mounted on a support such as a plate or hub. To stop the worktable at a selected stop point, each stop member can be positioned to engage an object, for convenience referred to herein as a bumper, that is connected to the moveable worktable to halt movement when the correct position has been reached. The apparatus includes means such as an actuator operatively associated to provide relative aligning movement between the stop member and bumper for placing the bumper and a selected one of the stop members in alignment with each other. The support for the stop member, e.g., a plate or hub, includes a bore or passage that extends entirely through it for each stop member so that each stop member can project out through both sides of the support. Consequently, the stop member can be fully retracted or extended its full length with respect to the support.
