Abstract

L'INVENTION CONCERNE L'INDUSTRIE DES APPAREILS DE MESURE. DEUX PINCEAUX LUMINEUX 3, 4, PRODUITS PAR EXEMPLE PAR DES SOURCES LASER 1, 2, DE COULEURS DIFFERENTES, SONT DEVIES PAR DEUX MIROIRS OSCILLANTS 5, 6 ET DIRIGES SUR UNE SURFACE DE PROFIL 12. ON PROJETTE LEURS IMAGES 13, 14 AU MOYEN D'UN OBJECTIF 15, SUR DEUX RESEAUX 17, 18, FORMES D'ELEMENTS PHOTOSENSIBLES. CONNAISSANT LA POSITION ANGULAIRE DE CHAQUE MIROIR OSCILLANT 5, 6, ET LA VALEUR DE L'ECART SEPARANT LES POINTS D'INCIDENCE 13, 14, ON PEUT DETERMINER LA DISTANCE DE CHAQUE POINT DE LA COURBE DE PROFIL 12 PAR RAPPORT AU DISPOSITIF DE MESURE, ET DONC AVOIR LE TRACE EXACT DE CETTE COURBE DE PROFIL. PAR ROTATION DE L'APPAREIL AUTOUR D'UN AXE 19, ON PEUT EXPLORER DES SERIES DE COURBES DE PROFIL SUCCESSIVES, TELLES QUE 12, 12. APPLICATION AUX MESURES DE DISTANCE ET AUX RELEVES DE PROFILS DE PIECES A USINER, NOTAMMENT POUR COMMANDER AUTOMATIQUEMENT UN MANIPULATEUR D'ATELIER.THE INVENTION CONCERNS THE INDUSTRY OF MEASURING EQUIPMENT. TWO LIGHT BRUSHES 3, 4, PRODUCED FOR EXAMPLE BY LASER SOURCES 1, 2, OF DIFFERENT COLORS, ARE DRIVEN BY TWO OSCILLATING MIRRORS 5, 6 AND DIRECTED ON A SURFACE OF PROFILE 12. THEIR IMAGES 13, 14 ARE PROJECTED BY MEANS OF D 'AN OBJECTIVE 15, ON TWO NETWORKS 17, 18, FORMS OF PHOTOSENSITIVE ELEMENTS. KNOWING THE ANGULAR POSITION OF EACH OSCILLATING MIRROR 5, 6, AND THE VALUE OF THE DIFFERENCE BETWEEN THE POINTS OF IMPACT 13, 14, WE CAN DETERMINE THE DISTANCE OF EACH POINT OF THE CURVE OF PROFILE 12 FROM THE MEASURING DEVICE, AND THEREFORE HAVE THE EXACT TRACE OF THIS PROFILE CURVE. BY ROTATION OF THE UNIT AROUND AN AXIS 19, ONE CAN EXPLORE SERIES OF SUCCESSIVE PROFILE CURVES, SUCH AS 12, 12. APPLICATION TO DISTANCE MEASUREMENTS AND SURVEY OF WORKPIECES PROFILES, IN PARTICULAR TO AUTOMATICALLY ORDER A WORKSHOP MANIPULATOR.
