Title (EN) APPARATUS AND METHOD FOR CHECKING DIAMETRAL DIMENSIONS OF AN ORBITALLY ROTATING PIN
(FR) APPAREIL ET PROCÉDÉ DE VÉRIFICATION DES DIMENSIONS DIAMÉTRALES D'UNE BROCHE À ROTATION ORBITALE
Abstract:
(EN) An apparatus for checking the diameter of crankpins (15) of a crankshaft in orbital motion about a geometrical axis in a numerical control machine tool includes a V-shaped reference device (10), a measuring device (6) and a support device (4) fixed to the tool holding slide (2) that movably supports the reference device and the measuring device. A control device (50) for controlling automatic displacements of the apparatus towards and away from a checking condition, includes a programmable electric motor (60) and a transmission mechanism (62). The programmable electric motor is programmed to define a start position in which the automatic displacement of the apparatus away from the checking condition can be stopped, for instance a rest position or an intermediate position between the rest position and the checking condition. The programmable electric motor is also programmed to define a displacement speed and a checking method includes steps for controlling the automatic displacements towards the checking condition.
(FR) L'invention concerne un appareil destiné à vérifier le diamètre de manetons (15) d'un vilebrequin dans un mouvement orbital autour d'un axe géométrique dans une machine-outil à commande numérique, comprenant un dispositif de référence en forme de V (10), un dispositif de mesure (6) et un dispositif de support (4) fixé au coulisseau porte-outil (2), qui soutient de manière mobile le dispositif de référence et le dispositif de mesure. Un dispositif de commande (50), destiné à commander des déplacements automatiques de l'appareil vers et à l'opposé d'un état de vérification, comprend un moteur électrique programmable (60) et un mécanisme de transmission (62). Le moteur électrique programmable est programmé en vue de définir une position de départ dans laquelle le déplacement automatique de l'appareil à l'opposé de l'état de vérification peut être arrêté, par exemple une position de repos ou une position intermédiaire entre la position de repos et l'état de vérification. Le moteur électrique programmable est également programmé en vue de définir une vitesse de déplacement, et un procédé de vérification comprend des étapes destinées à commander les déplacements automatiques vers l'état de vérification.
