Abstract: An automatic measuring station for measuring the dimensions of workpieces comprising a conveyor for loading and unloading workpieces; a slide supporting, through parallel leaf springs having the ends clamped to the slide, positioning and reference elements adapted to contact the workpieces for displacing and positioning them into the measurement positions; stationary positioning and reference elements adapted to cooperate with the workpieces for positioning them, together with the positioning and reference elements supported by the slide and displaceable with respect to the slide; and measuring heads provided with measuring elements adapted to cooperate with the surface of the workpieces for measuring their maximum dimension in which the measuring heads are fixed to the positioning and reference elements supported by the slide through the leaf springs.
