Abstract
A device that makes it possible to make the movements of moving platforms safer and relates more particularly to a linear actuator that can be used in a hexapod positioner supporting a load is provided. The actuator is actuated by electric control and comprises at least one hydraulic damper positioned on the actuator such that the forces generated by damping in the event of extreme breakdown are experienced only by the load and are distributed such as to limit force and acceleration peaks.
Claims12
A linear actuator actuated by electric control and that can be used in a hexapod positioner, said hexapod positioner comprising six linear actuators actuated by electric control and wherein each actuator has a leg of fixed length, an upper end of which is attached to a moving platform supporting a load and the other, lower end of which is moving along a guide rail, each of said six linear actuators comprises at least one hydraulic damper with calibrated orifices that is positioned on the guide rail and proximate a carriage on which the lower end of the leg rests, the calibration and the position of said at least one hydraulic damper being defined as a function of said load such that the forces generated by damping in the event of extreme breakdown are experienced only by said load and are distributed such as to limit force and acceleration peaks.
