  • a further protective device for example a magnetic switch, can be installed for additional protection against a possible adjustment of the device 1 during use of the edge milling machine 3, in order to ensure an additional or even more reliable determination of the height of the milling spindle 2.
  • a protective device could be activated as soon as the milling spindle 2 is set in rotation.

Abstract

L'invention concerne un dispositif (1) pour le réglage d'une broche de fraisage (2) rotative d'une machine à chanfreiner (3) le long d'un axe longitudinal (x) de la broche de fraisage (2). Le dispositif comprend les caractéristiques suivantes : un élément de réglage (6) agissant, pour le réglage de la broche de fraisage (2) en direction de l'axe longitudinal (x), sur celle-ci, un élément d'actionnement (5) relié à l'élément de réglage (6), de telle sorte qu'une rotation de l'élément d'actionnement (5) entraîne un déplacement de l'élément de réglage (6) en direction de l'axe longitudinal (x), un boîtier (4), par rapport auquel l'élément d'actionnement (5) est monté en rotation et auquel l'élément de réglage (6) est relié de manière solidaire en rotation au moins directement, un dispositif de blocage (9), au moyen duquel l'élément d'actionnement (5) est fixé sur le boîtier (4) de manière immobile en direction de l'axe longitudinal (x), un dispositif de fixation (12), au moyen duquel la possibilité de rotation de l'élément d'actionnement (5) peut être au moins restreinte.
