Description

Die Erfindung betrifft eine Finishvorrichtung, umfassend einen Andrückarm und ein Andrückwerkzeug zum Andrücken eines Finishwerkzeugs gegen ein Werkstück, gemäß EP 1 447 170 A1 und US 4,993,191 A .The invention relates to a finishing device, comprising a pressing arm and a pressing tool for pressing a finishing tool against a workpiece, according to EP 1 447 170 A1 and US 4,993,191 A ,

Finishvorrichtungen sind beispielsweise aus der EP 2 212 058 B1 und aus der DE 20 2013 005 504 U1 bekannt. Sie dienen dazu, ein Finishwerkzeug (beispielsweise ein Finishband) gegen eine finishend zu bearbeitende Werkstückoberfläche zu drücken. Dabei rotiert das Werkstück und wird gleichzeitig parallel zu der Rotationsachse oszillierend hin- und herbewegt. Hierdurch entsteht eine für das Finishverfahren charakteristische Kreuzschliffstruktur.Finish devices are for example from the EP 2 212 058 B1 and from the DE 20 2013 005 504 U1 known. They serve to press a finishing tool (for example, a finishing belt) against a finish to be machined workpiece surface. In this case, the workpiece rotates and is simultaneously oscillated back and forth parallel to the axis of rotation. This results in a characteristic of the finishing process cross-cut structure.

Bei den aus der EP 2 212 058 B1 und aus der DE 20 2013 005 504 U1 bekannten Finishvorrichtungen ist das Andrückwerkzeug mittels einer einfachen Verschraubung mit dem Andrückarm verbunden. Aus der DE 20 2014 000 094 U1 ist eine weitere Finishvorrichtung bekannt.In the from the EP 2 212 058 B1 and from the DE 20 2013 005 504 U1 Known finishing devices, the pressure tool is connected by means of a simple screw with the Andrückarm. From the DE 20 2014 000 094 U1 Another finishing device is known.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Montage eines Andrückwerkzeugs zu vereinfachen.The present invention has for its object to simplify the installation of a pressure tool.

Diese Aufgabe wird bei einer Finishvorrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved in a finishing device with the features of the preamble of claim 1 according to the invention by the characterizing features of claim 1.

Erfindungsgemäß ist ein Grundträger vorgesehen, dessen Lage und/oder Position relativ zu dem Andrückarm mittels einer Einstelleinrichtung einstellbar ist. Wenn der Grundträger eine gewünschte Lage und/oder Position relativ zu dem Andrückarm einnimmt, kann der Grundträger mittels der ersten Verbindungseinrichtung an dem Andrückarm fixiert werden. Die zweite Verbindungseinrichtung dient dazu, den Grundträger mit dem Andrückwerkzeug zu verbinden. Das Andrückwerkzeug muss dann nicht mehr relativ zu dem Andrückarm ausgerichtet werden, sondern lediglich mit dem Grundträger verbunden werden. Dies ermöglicht einen einfachen und schnellen Austausch eines Andrückwerkzeugs, welches verschleißbedingt oder zur Vorbereitung eines neuen Werkstückloses montiert werden soll.According to the invention, a base support is provided whose position and / or position can be adjusted relative to the pressing arm by means of an adjusting device. If the basic carrier assumes a desired position and / or position relative to the pressing arm, the basic carrier can be fixed to the pressing arm by means of the first connecting device. The second connection device serves to connect the base support with the pressure tool. The pressing tool then no longer has to be aligned relative to the pressure arm, but merely connected to the base support. This allows a simple and quick replacement of a pressing tool, which is due to wear or to be mounted to prepare a new workpiece lot.

Darüber hinaus ermöglicht es die zweite Verbindungseinrichtung, Andrückwerkzeuge in Form von Einrichtwerkzeugen mit dem Grundträger zu verbinden. Solche Einrichtwerkzeuge können gegebenenfalls stabiler ausgebildet sein als Andrückwerkzeuge, welche als Arbeitswerkzeug verwendet werden, um beispeilsweise ein Finishband gegen eine finishend zu bearbeitende Werkstückoberfläche zu drücken.In addition, the second connecting device makes it possible to connect pressing tools in the form of set-up tools to the basic carrier. Such setting tools may optionally be made more stable than pressing tools, which are used as a working tool, for example, to press a finishing belt against a finish to be machined workpiece surface.

Bevorzugt ist es, wenn das Andrückwerkzeug ein Andrückband und einen Andrückbandhalter umfasst. Der Andrückbandhalter weist einen Verbindungsabschnitt zur Verbindung mit einem Verbindungsabschnitt des Grundträgers auf. Diese Verbindungsabschnitte bilden die zweite Verbindungseinrichtung.It is preferred if the pressing tool comprises a pressing belt and a Andrückbandhalter. The Andrückbandhalter has a connecting portion for connection to a connecting portion of the base support. These connection sections form the second connection device.

Bei dem Andrückband handelt es sich insbesondere um ein biegbares Band, welches zur Finishbearbeitung von Werkstückoberflächen mit unterschiedlichen Durchmessern verwendbar ist. Dabei umschlingen das Andrückband und das Finishband die finishend zu bearbeitende Werkstückoberfläche über einen Umschlingungswinkel hinweg, welcher beispielsweise größer als 10° oder 20° beträgt.In particular, the pressure belt is a bendable belt which can be used for finish machining workpiece surfaces with different diameters. In this case, the pressure belt and the finishing belt wrap around the finish to be machined workpiece surface over a wrap angle, which, for example, is greater than 10 ° or 20 °.

Ferner ist es bevorzugt, wenn die Finishvorrichtung ein Andrückwerkzeug mit einem starr ausgebildeten Andrückabschnitt aufweist. Ein solches Andrückwerkzeug ist mechanisch robust und kann beispielsweise als Einrichtwerkzeug im Zuge der Vorbereitung der Fertigung eines Werkstückloses verwendet werden, aber alternativ oder zusätzlich hierzu auch als Arbeitswerkzeug. Sowohl ein Andrückwerkzeug in Form eines Arbeitswerkzeugs als auch ein Andrückwerkzeug in Form eines Einrichtwerkzeugs sind vorzugsweise wiederholbar lösbar mit dem Grundträger verbunden, sodass beliebige Andrückwerkzeuge einfach und schnell von dem Grundträger gelöst und mit diesem verbunden werden können.Furthermore, it is preferred if the finishing device has a pressing tool with a rigidly formed pressing portion. Such a pressing tool is mechanically robust and can be used, for example, as a setting tool in the course of preparing for the production of a workpiece lot, but alternatively or additionally as a working tool. Both a pressing tool in the form of a working tool and a pressing tool in the form of a setting tool are preferably releasably connected releasably connected to the base support, so that any pressing tools can be easily and quickly released from the base support and connected to this.

Für den Fall, dass ein Andrückwerkzeug mit einem starr ausgebildeten Andrückabschnitt verwendet wird, ist es bevorzugt, dass der Andrückabschnitt schalen- oder prismenförmig ausgebildet ist. Ein solcher Andrückabschnitt ermöglicht eine groß- oder mehrflächige Anlage des Andrückabschnitts an Oberflächen eines Einrichtwerkstücks oder eines zu bearbeitenden Werkstücks. Diese Anlage vereinfacht die Ausrichtung des Grundträgers relativ zu dem Andrückarm mittels der Einstelleinrichtung.In the event that a pressing tool is used with a rigidly formed pressing portion, it is preferred that the pressing portion is formed like a shell or prism. Such a pressing portion allows a large or multi-surface contact of the Andrückabschnitts on surfaces Einrichtwerkstücks or one to machining workpiece. This system simplifies the alignment of the base carrier relative to the pressing arm by means of the adjusting device.

Bei einer besonders bevorzugten Ausführungsform ist vorgesehen, dass die erste Verbindungseinrichtung eine neigungseinstellbare Verschraubung umfasst, welche die Einstelleinrichtung bildet. Eine solche Verschraubung umfasst vorzugsweise Kugelscheiben und Kegelpfannen, welche relativ zueinander in ihrer Neigung eingestellt werden können, sodass eine Achse einer Schraube, welche die Kugelscheibe und Kegelpfanne durchsetzt, ebenfalls in ihrer Neigung einstellbar ist, um eine Neigung des Grundträgers relativ zu dem Andrückarm zu definieren. Eine einfache Möglichkeit zur Beeinflussung der Position des Grundträgers an dem Andrückarm besteht darin, den Grundträger oder den Andrückarm mit Langlöchern zu versehen, sodass die Position der Schraube und somit die Relativposition des Grundträgers relativ zu dem Andrückarm einstellbar ist.In a particularly preferred embodiment it is provided that the first connecting device comprises a tilt-adjustable screw which forms the adjusting device. Such a screw connection preferably comprises spherical discs and conical cups, which can be adjusted in their inclination relative to each other, so that an axis of a screw, which passes through the spherical disc and conical socket, is also adjustable in its inclination to define a slope of the base support relative to the Andrückarm , A simple way of influencing the position of the base carrier on the pressing arm is to provide the base carrier or the pressing arm with slots, so that the position of the screw and thus the relative position of the base support is adjustable relative to the pressing arm.

Bei einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der Grundträger einen insbesondere U-förmigen Halterahmen zur Befestigung an dem Andrückarm aufweist. Ein solcher Halterahmen ermöglicht eine einfache und toleranzgenaue Lagerung eines Andrückwerkzeugs an dem Grundträger.In a preferred embodiment of the invention it is provided that the base support has a particular U-shaped support frame for attachment to the Andrückarm. Such a support frame allows a simple and accurate tolerance storage of a pressure tool on the base support.

Der Grundträger kann einteilig ausgebildet sein. Der Grundträger kann auch mehrteilig ausgebildet sein und beispielsweise einen insbesondere U-förmigen Innenrahmen aufweisen, welcher an dem Halterahmen gehalten ist und welcher zum Halten des Andrückwerkzeugs dient. Es ist möglich, dass der Innenrahmen derart an dem Halterahmen gelagert ist, dass sich der Innenrahmen entlang oder um bestimmte Bewegungsachsen herum bewegen kann, um eine bewegliche Lagerung des Andrückwerkzeugs relativ zu dem Grundträger zu schaffen.The base support may be integrally formed. The base support may also be designed in several parts and, for example, have a particular U-shaped inner frame, which is held on the holding frame and which serves to hold the pressing tool. It is possible for the inner frame to be mounted on the holding frame in such a way that the inner frame can move along or around certain axes of movement in order to provide a movable mounting of the pressing tool relative to the basic carrier.

Bevorzugt ist es, wenn der Grundträger und das Andrückwerkzeug Anlageflächen aufweisen, welche die Relativposition des Andrückwerkzeugs an dem Grundträger definieren. Auf diese Weise überträgt sich eine an dem Grundträger relativ zu dem Andrückarm vorgenommene Einstellung der Lage und/oder Position des Grundträgers auf das Andrückwerkzeug.It is preferred if the base support and the pressure tool have contact surfaces which define the relative position of the pressure tool on the base support. In this way, an adjustment of the position and / or position of the base carrier made on the base carrier relative to the pressing arm is transmitted to the pressing tool.

Die zweite Verbindungseinrichtung kann im einfachsten (nicht erfindungsgemäßen) Fall durch eine Verschraubung gebildet sein.The second connection device can be formed by a screw connection in the simplest case (not according to the invention).

Erfindungsgemäß ist die zweite Verbindungseinrichtung werkzeuglos betätigbar und ist als Rastverbindung ausgebildet. Dies ermöglicht es, eine Schnellwechsel-Schnittstelle zwischen dem Andrückwerkzeug und dem Grundträger zu schaffen.According to the invention, the second connection device can be actuated without tools and is designed as a latching connection. This makes it possible to provide a quick-change interface between the pressing tool and the base support.

Erfindungsgemäß umfasst die zweite Verbindungseinrichtung ein Rastelement, welches in einer Ruhestellung eine Verriegelungsstellung zur Verriegelung des Andrückwerkzeugs an dem Grundträger einnimmt und welches insbesondere handbetätigbar in eine Freigabestellung überführbar ist, in welcher das Andrückwerkzeug von dem Grundträger lösbar ist. Dies ermöglicht eine besonders schnelle Befestigung eines Andrückwerkzeugs an dem Grundträger und ein besonders schnelles Lösen des Andrückwerkzeugs von dem Grundträger. Dies ist insbesondere dann vorteilhaft, wenn der Grundträger bereits mittels der Einstelleinrichtung relativ zu dem Andrückarm ausgerichtet ist.According to the invention, the second connecting device comprises a latching element, which occupies a locking position for locking the pressing tool on the base carrier in a rest position and which in particular can be moved manually into a release position, in which the pressing tool is detachable from the base carrier. This allows a particularly fast attachment of a pressure tool to the base support and a particularly rapid release of the pressure tool from the base support. This is particularly advantageous if the base support is already aligned by means of the adjustment relative to the Andrückarm.

Die vorstehend beschriebenen zweiten Verbindungseinrichtungen sind auch vorteilhaft für Finishvorrichtungen, welche keine Einstelleinrichtung zur Einstellung der Position und/oder Lage des Grundträgers relativ zu dem Andrückarm aufweisen und bei denen lediglich eine erste Verbindungseinrichtung zur Verbindung des Grundträgers mit dem Andrückarm vorgesehen ist.The second connecting means described above are also advantageous for finishing devices, which have no adjustment for adjusting the position and / or position of the base support relative to the Andrückarm and in which only a first connection means for connecting the base support is provided with the Andrückarm.

Die eingangs genannte Aufgabe wird auch durch ein Verfahren zur Einrichtung einer vorstehend beschriebenen Finishvorrichtung gelöst, bei welchem ein als Einrichtwerkzeug ausgebildetes Andrückwerkzeug mit dem Grundträger verbunden wird, das Andrückwerkzeug an ein Einrichtwerkstück oder an ein finishend zu bearbeitendes Werkstück angelegt wird, um den Grundträger auszurichten und die Lage und/oder Position des Grundträgers zu bestimmen, bei welchem ferner der Grundträger an dem Andrückarm befestigt wird, das Einrichtwerkzeug entfernt und ein als Bearbeitungswerkzeug ausgebildetes Andrückwerkzeug mit dem Grundträger verbunden wird.The object mentioned at the outset is also achieved by a method for setting up a finishing device described above in which a pressing tool designed as a setting tool is connected to the base support, the pressing tool is applied to a set-up piece or to a workpiece to be finish-finished in order to align the base support and determine the position and / or position of the base support, wherein further, the base support is attached to the Andrückarm, removes the Einrichtwerkzeug and designed as a machining tool Pressing tool is connected to the base support.

Hinsichtlich der Vorteile und Ausgestaltungen des vorstehend genannten Verfahrens wird auf Vorteile und Ausgestaltungen der vorstehend beschriebenen Finishvorrichtung Bezug genommen.With regard to the advantages and refinements of the aforementioned method, reference is made to advantages and refinements of the above-described finishing device.

Der Andrückbandhalter 80 ist hinsichtlich seiner mit dem Grundträger 44 zusammenwirkenden Flächen identisch zu dem Andrückwerkzeug 62 in Form des Einrichtwerkzeugs. Dementsprechend kann der Andrückbandhalter 80 mittels der zweiten Verbindungseinrichtung 60 mit dem Grundträger 44 verbunden werden. Dabei nimmt das Andrückwerkzeug 78 bereits eine vorbestimmte Lage und Position relativ zu dem Andrückarm 18, 20 ein. Daher kann nach Positionierung des Andrückwerkzeugs 78 an einer finishend zu bearbeitenden Oberfläche 84 des Werkstücks 34 (durch Schließen der zangenartigen Andrückarme 18, 20) unmittelbar mit der Bearbeitung der Oberfläche 84 begonnen werden, ohne dass weitere Einstellvorgänge erforderlich sind.The pressing tool 78 has a Andrückbandhalter 80 for holding a Andrückbands 82. The Andrückbandhalter 80 is identical in terms of its co-operating with the base support 44 surfaces to the pressure tool 62 in the form of the Einrichtwerkzeugs. Accordingly, the Andrückbandhalter 80 can be connected by means of the second connecting means 60 with the base support 44. In this case, the pressing tool 78 already assumes a predetermined position and position relative to the pressing arm 18, 20 a. Therefore, after positioning the pressing tool 78 on a surface finish 84 of the workpiece 34 (by closing the pincer-like pressing arms 18, 20), machining of the surface 84 can begin immediately without requiring further adjustment operations.

Während der finishenden Bearbeitung des Werkstücks 34 rotiert dieses um eine Werkstückachse 32. Hierfür ist ein an sich bekannter und daher nicht dargestellter Rotationsantrieb vorgesehen. Dieser Rotationsbewegung wird eine Oszillationsbewegung überlagert, nämlich eine Bewegung in einander entgegengesetzten Richtungen parallel zu der Werkstückachse 32. Hierfür ist ein an sich bekannter und daher ebenfalls nicht dargestellter Oszillationsantrieb vorgesehen.During the finish machining of the workpiece 34, this rotates about a workpiece axis 32. For this purpose, a per se known and therefore not shown rotary drive is provided. This rotational movement is superimposed on an oscillatory movement, namely a movement in opposite directions parallel to the workpiece axis 32. For this purpose, a per se known and therefore also not shown oscillating drive is provided.
