Abstract

Dispositif de mesure numérique des dimensions de pièces, comprenant deux palpeurs portés par deux bras parallèles déplaçables en sens inverse dont l'un est relié à une échelle explorée par un organe de lecture. L'autre bras 13 est relié à une plaque à traits 17 ayant sensiblement la même longueur que l'échelle 16 reliée au bras 12 et un organe de lecture fixe 18 explore l'échelle 16 et la plaque à traits 17. Application: notamment à la mesure des dimensions intérieures ou extérieures de pièces sur des machines-outils.Device for digital measurement of the dimensions of parts, comprising two probes carried by two parallel arms which can be moved in the opposite direction, one of which is connected to a scale explored by a reading member. The other arm 13 is connected to a line plate 17 having substantially the same length as the scale 16 connected to the arm 12 and a fixed reading member 18 explores the scale 16 and the line plate 17. Application: in particular to measuring the internal or external dimensions of parts on machine tools.
