Abstract
A protection device (D) for the driving mechanism of a mobile element (O) against the cuttings of a machine tool includes a driving section (P1) and a machining zone (P2) separated by a protection wall. The protection wall is constituted by a plate (100) having a free translational motion on a disk (200) rotating freely with respect to the wall. A first displacement window (210) in the disk (200), and a second displacement window (310) in the wall are provided wherein both displacement windows (210 and 310) are arranged with respect to each other in such a way that the translational displacement of the plate (100) and the rotation of the disk (200) occlude the opening of both displacement windows (210 and 310).
Claims7
A protection device for protecting driving elements of a mobile element from cuttings produced by a machine tool having a driving section and a machining zone with a protection wall separating the driving section from the machining section, a protection device comprising a cabin, a first displacement window in the disk and a second displacement window in the cabin, a plate interdependent from a cross-through portion of the mobile element slidably mounted on the disk for free translational motion relative to the disk, both displacement windows being arranged with respect to each other so that displacement of the mobile element in said second window in a plane perpendicular to a rotation axis of the disk simultaneously causes sliding of said plate on the disk and the rotation of the disk so that said translational displacement of the plate and the rotation of the disk occlude an opening defined by both displacement windows.
