Abstract
The invention relates to a positioning device with an X-beam (,) and two parallel Y-beams (,) in the shape of an H. On each Y-beam a motor driven carriage (,) is provided. Between these carriages an X-beam is coupled. On the X-beam a carriage (,) with a positioning head (,) is provided. The coupling (,) between one end of the X-beam and the carriage (,) on the first Y-beam (,) comprises two leaf springs (,) perpendicular to each other, the intersecting line of said leaf springs forming an imaginary rotation axis (,) of the coupling. The coupling (,) between the other end of the X-beam and the carriage (,) on the other, second Y-beam (,) comprises one leaf spring (,) oriented in the Y-direction and having a relatively great stiffness in the Y-direction and a relative small stiffness in the X-direction. Advantage of these couplings: no play, frictionless, possibility of small angle correction for the positioning head.
