Abstract

Abstract Translated from French Cet appareil permet de trouver les axes des trous transversaux (t1 et t2) de la broche à l'aide d'un guide de perçage (6) sans qu'il soit nécessaire d'apercevoir les trous ou d'employer des rayons X. A cet effet, le guide de perçage (6) est réglable sur une monture (3) selon deux degrés de liberté, le réglage étant effectué en fonction d'informations de position relatives à l'axe du trou (t1, t2) et relevées par des moyens palpeurs (14) qui peuvent être insérés dans la broche (B). Ces moyens palpeurs sont mécaniques et/ou utilisent un rayonnement non traumatisant tel que la lumière éventuellement pulsée.
