Abstract
(EN)
Non-contact apparatus for positioning a surface working, testing or inspection device (1) relative to a surface to be worked, tested or inspected (2) at a desired position and orientation relative thereto (3b) including a baseplate (4) locatable at a distance away from the surface (2), means (5) for mounting the surface working, testing or inspection device on the baseplate (4), three or more range finder units (6a, 6b, 6c) removably mounted in spaced array (6d) on the baseplate (4), each of which three or more range finder units (6a, 6b, 6c) includes a source (7) for impinging a beam (8) of ultraviolet, visible light or infrared radiation on the surface (12), a detector (9) for imaging the impinging radiation (12) and for calculating a distance measurement (10a) from a datum location on the respective source (11a).
(FR)
L'invention se rapporte à un appareil de positionnement sans contact d'un dispositif d'examen, de vérification et de travail de surfaces, par rapport à une surface (2) à travailler, à vérifier ou à examiner, en un emplacement souhaité et selon une orientation souhaitée (3b). Ledit appareil comporte une plaque de base (4) susceptible d'être placée à une certaine distance de la surface (2), un organe (5) de montage du dispositif d'examen, de vérification et de travail de surfaces sur la plaque de base (4), au moins trois unités télémétriques (6a, 6b, 6c) montées de manière amovible en un ensemble espacé (6d) sur la plaque de base (4). Chacune de ces unités télémétriques (6a, 6b, 6c) comporte une source (7) conçue pour diriger un faisceau d'ultraviolet, de lumière visible ou de rayonnement infrarouge sur la surface (12), un détecteur (9) conçu pour produire une image du rayonnement incident (12) et pour calculer une mesure de distance (10a) à partir d'un emplacement de référence sur la source respective (11a).
