Abstract
A high-precision linear actuator is described that includes a first straight-guide mechanism that guides movements of an actuator element and a working device relative to an actuator housing. A pressing mechanism that, in a pressing-contact condition, presses the actuator frame and the actuator housing with a predetermined force against one another. A second straight-guide mechanism that guides movements of the actuator housing relative to the actuator frame between the pressing-contact condition and released-contact conditions in which the pressing mechanism presses the actuator frame and the actuator housing towards one another. The high-precision linear actuator provides a safety mechanism automatically reinstates negative consequences of unforeseen collisions in the working environment. In addition the high-precision linear actuator allows for a compact and light-weight design of the actuator element and the working device, which improves operational speed and effectivity of the linear actuator.
