CA 2718224

A first thread feature is measured by detecting with an optical sensor 2 light that reaches from a light source 21 located on the opposite side of a pipe axis and runs substantially in parallel to thread grooves A4. A contact probe 31 of a contact sensor 3 is contacted with a thread flank surface A8 to detect the space coordinates of the contact probe 31 at the time of contact, so that a second thread feature is measured. The first and second thread features thus detected are combined with each other by a processor 4, and thread features of the thread provided as a measurement object are thereby calculated.

Selon l'invention, un premier élément de vis est mesuré par détection de lumière qui est sensiblement parallèle à une rainure de vis (A4) parmi des lumières fuyant vers le côté opposé à une source lumineuse (21) par rapport à l'axe de tuyau, à l'aide d'un détecteur optique (2). Un second élément de vis est mesuré par mise en contact par toucher de la sonde de contact (31) d'un détecteur de contact (3) avec la face de flanc (A8) d'une vis et par détection de la coordonnée spatiale de la sonde de contact (31) au moment du contact. Les premier et second éléments de vis ainsi détectés sont synthétisés par des moyens de traitement d'opération (4), et un élément de vis d'une vis d'objet de mesure est actionné.
