Title (EN) BELT-FINISHING UNIT AND PRESSING DEVICE THEREFOR
(FR) UNITÉ DE FINISSAGE DE BANDE ET DISPOSITIF DE PRESSION ASSOCIÉ
(DE) BANDFINISHEINHEIT UND ANDRÜCKEINRICHTUNG DAFÜR
Abstract:
(EN) A belt-finishing unit (100) for a belt-finishing machine comprises a base element (120) having devices for mounting the base element on a frame part of a belt-finishing machine, a pressure arm (130A), which is supported in a movable manner in the region of a supporting portion (132) and has, away from the supporting portion, a mounting portion (138) for fastening an exchangeable pressing device (150) on the pressure arm, and an exchangeable pressing device (150), fastened to the mounting portion, for pressing finishing belt (190) against a circumferential face (114) of a substantially cylindrical workpiece portion (116) during belt finishing machining, wherein the pressing device comprises a carrier device (160) and at least one flexible pressing belt (170) which is substantially non-elastic in the belt direction and is supported on two spaced-apart bearings of the carrier device such that the finishing belt is able to be pressed flat against the circumferential face over an engagement angle by means of the pressing belt during finishing machining. Furthermore, components of a monitoring system (200) for monitoring operating states of the belt-finishing unit are provided. The pressing device (150) has at least one tool-side component (210) of the monitoring system, said component (210) being exchangeable with the pressing device.
(FR) La présente invention concerne une unité de finissage de bande (100) pour une machine de finissage de bande, comprenant un élément de base (120) doté de dispositifs de montage de l'élément de base à une partie de châssis d'une machine de finissage de bande, un bras de pression (130A), lequel est monté mobile dans la zone d'une section d'appui (132) sur l'élément de base (120) et lequel comporte, à une distance de la section d'appui, une section de montage (138), pour monter un dispositif de pression (150) interchangeable sur le bras de pression, et un dispositif de pression (150) interchangeable, monté sur la section de montage, pour presser la bande de finissage (190) contre une surface circonférentielle (114) d'une section de pièce à usiner (116) sensiblement cylindrique lors de l'usinage de finition de la bande, le dispositif de pression comprenant un dispositif de support (160) et au moins une bande de pressage (170) élastique en flexion, laquelle est sensiblement inélastique dans la direction de la bande et laquelle est montée sur deux paliers espacés l'un de l'autre du dispositif de support de sorte que la bande de finissage, lors de l'usinage de finition, peut être pressée, au moyen de la bande de pressage, sous un angle de pression, de manière plane, contre la surface circonférentielle. En outre, la présente invention concerne des composants d'un système de surveillance (200), destinés à surveiller les états de fonctionnement de l'unité de finissage de bande. Le dispositif de pression (150) comporte au moins un composant côté outil (210) du système de surveillance, interchangeable avec le dispositif de pression.
(DE) Eine Bandfinisheinheit (100) für eine Bandfinishmaschine umfasst ein Basiselement (120) mit Einrichtungen zur Montage des Basiselements an einem Gestellteil einer Bandfinishmaschine, einen Druckarm (130A), der im Bereich eines Lagerabschnitts (132) an dem Basiselement (120) beweglich gelagert ist und entfernt von dem Lagerabschnitt einen Montageabschnitt (138) zum Befestigen einer auswechselbaren Andrückeinrichtung (150) an dem Druckarm aufweist, und eine an dem Montageabschnitt befestigte auswechselbare Andrückeinrichtung (150) zum Andrücken von Finishband (190) an eine Umfangsfläche (114) eines im Wesentlichen zylindrischen Werkstückabschnitts (116) bei einer Bandfinishbearbeitung, wobei die Andrückeinrichtung eine Trägereinrichtung (160) und mindestens ein biegeelastisches Andrückband (170) umfasst, das in Bandrichtung im Wesentlichen inelastisch ist und an zwei mit Abstand zueinander angeordneten Lagern der Trägereinrichtung derart gelagert ist, dass das Finishband bei einer Finishbearbeitung mittels des Andrückbandes über einen Eingriffswinkel flächig an die Umfangsfläche andrückbar ist. Weiterhin sind Komponenten eines Überwachungssystems (200) zur Überwachung von Betriebszuständen der Bandfinisheinheit vorgesehen. Die Andrückeinrichtung (150) weist mindestens eine mit der Andrückeinrichtung auswechselbare werkzeugseitige Komponente (210) des Überwachungssystems aufweist.
