Description

Die Erfindung betrifft ein insbesondere für Schleif-und Polierarbeiten einsetzbares Vorsatzteil bei Werkmaschinen, mit einer Antriebsscheibe, die auf einer Seite eine Klettschicht und auf der anderen Seite eine auf einen starren Lauf umrüstbare biegsame Welle aufweist, und einer Arbeitsscheibe, die werkstückseitig mit einer Bearbeitungsscheibe und antriebsseitig mit einem mit der Klettschicht der Antriebsscheibe unter Bildung eines Klettverschlusses verbindbaren Gewebe versehen ist.The invention relates to a front part that can be used in particular for grinding and polishing work in machine tools, with a drive pulley that has a Velcro layer on one side and a flexible shaft that can be converted to a rigid barrel on the other side, and a working disk that has a machining disk on the workpiece side and on the drive side is provided with a fabric that can be connected to the Velcro layer of the drive pulley to form a Velcro fastener.

Vorsatzteile mit Antriebsscheiben, die durch Werkmaschinen, z.B. Bohrmaschinen, in schnell umlaufende Bewegung versetzt werden und die werkstückseitig eine Arbeitsscheibe tragen, sind bekannt.Front parts with drive pulleys, which are Drills are set in fast rotating motion and carry a work disc on the workpiece side are known.

Es ist weiterhin bekannt, die Verbindung zwischen Antriebsscheibe und Arbeitsscheibe durch einen Klettverschluß herzustellen, so daß z.B. bei Abnutzung oder Wechsel der Arbeitsscheibe ein Austausch schnell erfolgen kann.It is also known to make the connection between the drive pulley and the working pulley by means of a Velcro fastener, so that e.g. if the working disc is worn or changed, it can be replaced quickly.

Je nachdem welche Arbeiten durchgeführt werden, wird man die Achse der Vorsatzteile durch Einsatz einer biegsamen Welle flexibel halten oder nicht. Besonders für Schleifarbeiten sind Vorsatzteile derart gestaltet, daß sie neben der flexiblen Welle auf der Unterseite der Antriebsscheiben eine Schaumstoffschicht besitzen, wodurch die Schleifleistung verbessert wird. Nachteilig eignen sich diese Vorsatzteile nicht für Arbeiten, die mit starrer Welle und hoher Umdrehungszahl ausgeführt werden, während mit Vorsatzteilen ohne Schaumstoffschicht bei Schleif- und Polierarbeiten keine optimalen Ergebnisse erzielbar sind. Depending on the work to be carried out, the axis of the front parts is made using a flexible shaft keep flexible or not. Especially for grinding work, attachment parts are designed in such a way that they have a foam layer on the underside of the drive disks in addition to the flexible shaft, which improves the grinding performance. Disadvantageously, these attachments are not suitable for work that is carried out with a rigid shaft and a high number of revolutions, while optimal results cannot be achieved with attachments without a foam layer during grinding and polishing work.

Der Erfindung liegt die Aufgabe zugrunde, ein Vorsatzteil, der obengenannten Art so zu gestalten, daß es für sämtliche Schleif- und Polierarbeiten einsetzbar ist und auf schnelle und einfache Weise auf das jeweilige Einsatzgebiet umrüstbar ist.The invention has for its object to design a front part of the type mentioned above so that it can be used for all grinding and polishing work and can be quickly and easily converted to the respective area of application.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei dem Vorsatzteil die Arbeitsscheibe zweiteilig aufgebaut ist und aus einer gewebehinterlegten Bearbeitungsscheibe und einer Schaumstoffscheibe, deren Scheibenflächen jeweils mit einer Klett- und einer Gewebeschicht versehen sind, besteht.This object is achieved in that the working disc is constructed in two parts in the front part and consists of a fabric-backed processing disc and a foam disc, the disc surfaces of which are each provided with a Velcro and a fabric layer.

Bei dem erfindungsgemäßen Vorsatzteil wird einessichere und leicht lösbare Verbindung zwischen Antriebsscheibe, Schaumstoffschicht und Bearbeitungsscheibe jeweils durch Klettverschluß hergestellt. Das Vorsatzteil läßt sich für Arbeiten, die eine Schaumstoffzwischenschicht nicht erfordern, durch einfaches Entfernen dieser Schicht umrüsten, wodurch die bekannte Form des Vorsatzteils mit Antriebsscheibe und verbundener Arbeitsscheibe hergestellt wird.In the attachment part according to the invention, a secure and easily detachable connection between the drive disk, foam layer and processing disk is in each case made by means of a Velcro fastener. The attachment can be used for work that does not require an intermediate foam layer easy to remove this layer convert, whereby the known shape of the front part with drive pulley and connected work disc is produced.

Den unterschiedlichen Einsatzgebieten entsprechend gestaltet man die Arbeitsscheibe einmal als Poliertuch oder Poliervlies. Für Schleifarbeiten.sind Arbeitsscheiben vorgesehen, bei denen die Schleifkörner kunstharzgebunden sind. Mit diesen Schleifscheiben lassen sich wesentlich längere Standzeiten erzielen als mit Scheiben nach dem Stand der Technik, bei denen die Schleifkörnung auf einen mit der Unterlage verklebten Papierträger aufgebracht ist.Depending on the different areas of application, the worktop is designed as a polishing cloth or polishing fleece. For grinding work, working wheels are provided in which the abrasive grains are bonded with synthetic resin. With these grinding wheels, considerably longer service lives can be achieved than with prior art wheels, in which the abrasive grain is applied to a paper carrier glued to the base.

Zur Verlängerung der Standzeit des Vorsatzteiles ist weiterhin vorgesehen, die Klettschicht an der Antriebsscheibe einstückig anzuformen. Hierdurch wird vermieden, daß sich wie bei einer Antriebsscheibe nach dem Stand der Technik der Verbindungskleber zwischen Klettschicht und Antriebsscheibe durch Erwärmen bei hoher Belastung lösen kann.To extend the service life of the front part, it is also provided that the Velcro layer is integrally formed on the drive pulley. This prevents the connection adhesive between the hook-and-loop layer and the drive disk from becoming detached, as in the case of a drive disk according to the prior art, by heating under high loads.

Bei dem Vorsatzteil ist eine Welle vorgesehen, bei der zumindestens ein Teilstück biegsam ist und die einen Anschlag am antriebsseitigen Ende des biegsamen Teilstückes besitzt, mit einem Aufnahmeteil der Antriebsscheibe derart verbindbar, daß ihr biegsames Teilstück außerhalb des Aufnahmeteils liegt. Zur Umrüstung auf einen starren Lauf kann das biegsame Teilstück der Welle durch eine aufgesteckte Hülse, die zwischen Aufnahmeteil und Anschlag verklemmbar ist, festgesetzt werden.In the front part, a shaft is provided in which at least one section is flexible and which has a stop at the drive end of the flexible section, can be connected to a receiving part of the drive pulley in such a way that its flexible section lies outside the receiving part. For converting to a rigid barrel the flexible part of the shaft can be fixed by an attached sleeve that can be clamped between the receiving part and the stop.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

Es zeigen:

  • Figur 1 eine Ansicht des erfindungsgemäßen Vorsatzteils,
  • Figur 2 eine auseinandergezogene Darstellung des Vorsatzteils der Figur 1.
Show it:
  • FIG. 1 shows a view of the front part according to the invention,
  • FIG. 2 is an exploded view of the front part of FIG. 1.

Das in Figur 1 gezeigte Vorsatzteil weist eine Antriebsscheibe 1 mit einer Welle 2 und eine mit der Antriebsscheibe 1 haftend verbundene Arbeitsscheibe 3 auf.The front part shown in FIG. 1 has a drive disk 1 with a shaft 2 and a working disk 3 which is adhesively connected to the drive disk 1.

Auf der Unterseite der Antriebsscheibe 1 ist einstückig eine Klettschicht 4 angeformt, deren Elemente hakenförmig, pilzkopfartig oder auch T-förmig ausgebildet sein können. Mit der Klettschicht 4 ist die Arbeitsscheibe 3 über eine Gewebeschicht 5, die zum Beispiel aus Velours bestehen kann, unter Bildung eines Klettverschlusses ver-. bunden. Das in den Figuren gezeigte Ausführungsbeispiel des Vorsatzteils ist für Schleifarbeiten geeignet. Dazu ist die Arbeitsscheibe 3 zweiteilig aufgebaut und weist eine Bearbeitungsscheibe 6 und eine Schaumstoffscheibe 7 auf. Die Verbindung zwischen Bearbeitungsscheibe 6 und Schaumstoffscheibe 7 erfolgt wiederum durch einen Klettverschluß. Die Bearbeitungsscheibe 6 ist dazu mit einer Gewebeschicht 8 hinterlegt, während auf die Schaumstoffscheibe 7, die aus Hochdruck-PU-Schaum oder vergleichbaren Materialien besteht, auf der zur Bearbeitungsscheibe gerichteten Scheibenfläche eine Klettschicht 15 aufgebracht ist. Die Schichten 5 und 15 auf den Scheibenflächen der Schaumstoffscheibe können aufgeklebt sein, da bei den zum Planschleifen oder Polieren erforderlichen, relativ niedrigen Drehzahlen die Festigkeit des Klebers durch Erhitzung nicht beeinträchtigt wird. Im Gegensatz dazu ist bei der Bearbeitungsscheibe 6, die aus einem Kunstharzbett besteht, in das Schleifkörner eingesetzt sind, die Gewebeschicht 8 ohne Kleber mit dem Kunstharzbett verbunden.A Velcro layer 4 is integrally formed on the underside of the drive pulley 1, the elements of which can be hook-shaped, mushroom-shaped or T-shaped. With the Velcro layer 4, the working disc 3 is bonded to a Velcro fastener via a fabric layer 5, which can be made of velor, for example. bound. The embodiment of the front part shown in the figures is suitable for grinding work. For this purpose, the working disk 3 is constructed in two parts and has a processing disk 6 and a foam disk 7. The connection between the processing disc 6 and the foam disc 7 is again made by a Velcro closure. The processing disk 6 is to ewebeschicht with a G deposited 8, while, on the side facing the machining wheel disc face a Velcro layer 15 is applied to the foam disc 7, which consists of high pressure PU-foam or similar materials. The layers 5 and 15 on the disc surfaces of the foam pad may be glued, as lanschleifen or on the P polishing required, relatively low speeds, the strength of the adhesive by heating is not impaired. In contrast to this, in the processing disc 6, which consists of a synthetic resin bed into which abrasive grains are inserted, the fabric layer 8 is connected to the synthetic resin bed without adhesive.

Antriebsseitig weist die Antriebsscheibe 1 ein Aufnahmeteil 9 auf, in das die Welle 2 mit einem ein Schraubgewinde 10 aufweisenden Ende eingeschraubt ist. Zwischen Schraubgewinde 10 und einem Anschlag 11, dessen Querschnittsfläche zur Erleichterung der Montage der Welle 2 als Sechskant ausgebildet ist, besitzt die Welle 2 ein biegsames Teilstück 12. Der Anschlag 11 geht zur Antriebsseite in einen Schaftteil 13 über, das zum Beispiel in ein Bohrmaschinenfutter einsetzbar ist.On the drive side, the drive pulley 1 has a receiving part 9, into which the shaft 2 is screwed with an end having a screw thread 10. Between screw thread 10 and a stop 11, the cross-sectional area of which is designed to facilitate the assembly of the shaft 2 as a hexagon, the shaft 2 has a flexible section 12. The stop 11 merges into a shaft part 13 on the drive side, which can be used, for example, in a drill chuck is.

Bei eingeschraubter Welle 2 liegt das biegsame Teilstück 12 außerhalb des Aufnahmeteils 9. Das biegsame Teilstück 12 kann für einen starren Lauf der Welle durch eine Zylinderhülse 14 festgesetzt werden, die das biegsame Teilstück 12 übergreift und zwischen Aufnahmeteil 9 und Anschlag 11 festgeklemmt ist. Die Lage der Zylinderhülse 14 ist in Figur 1 gestrichelt angedeutet. Bei Bedarf kann die Zylinderhülse 14 durch Abschrauben der Welle 2 entfernt werden.When the shaft 2 is screwed in, the flexible section 12 lies outside the receiving part 9. The flexible section 12 can be fixed for a rigid running of the shaft by means of a cylinder sleeve 14 which holds the flexible section 12 overlaps and is clamped between the receiving part 9 and the stop 11. The position of the cylinder sleeve 14 is indicated by dashed lines in Figure 1. If necessary, the cylinder sleeve 14 can be removed by unscrewing the shaft 2.

Das Vorsatzteil ermöglicht in der in Figur 1 gezeigten Ausbildung mit biegsamer Welle und Schaumstoffzwischenschicht exaktes Schleifen auf ebenen Flächen. Für Feinschleifarbeiten kann die Bearbeitungsscheibe 6 des Vorsatzteils bei Entfernung der Schaumstoffscheibe 7 direkt vor die Arbeitsscheibe 1 gesetzt werden, wobei die beiden Scheiben durch Klettverschluß aneinander haften. Aufgrund der biegsamen Welle ist ein präzises Schleifen möglich. Die Bearbeitungsscheibe 6 kann auch aus einem Poliertuch oder Poliervlies bestehen, so daß mit dem Vorsatzteil sämtliche Polierarbeiten durchführbar sind.In the embodiment shown in FIG. 1 with a flexible shaft and foam intermediate layer, the front part enables exact grinding on flat surfaces. For fine grinding work, the processing disc 6 of the front part can be placed directly in front of the working disc 1 when the foam disc 7 is removed, the two discs adhering to one another by means of a Velcro fastener. Due to the flexible shaft, precise grinding is possible. The processing disc 6 can also consist of a polishing cloth or polishing fleece, so that all the polishing work can be carried out with the front part.

Durch Arretierung der Welle 2 über die Zylinderhülse 14 können ferner Schleifarbeiten durchgeführt werden, die einen Gleichlauf der Antriebsscheibe erfordern. Die Verbindung über den Klettverschluß zwischen Antriebsscheibe und Bearbeitungsscheibe ist so stabil, daß auch gewebehinterlegte Schleifscheiben als Bearbeitungsscheiben eingesetzt werden können. Antriebsscheibe mit Schleifscheibe sind dann in Werkmaschinen, z.B. Winkelschleifer mit passendem Anschlußgewinde, einsetzbar. Ersichtlicherweise ist das erfindungsgemäße Vorsatzteil für vielfältige Schleif- und Polierarbeiten geeignet und stellt daher eine ideale Lösung der anstehenden Probleme dar.By locking the shaft 2 over the cylinder sleeve 14 grinding work can be carried out that require the drive pulley to run in sync. The connection via the Velcro fastener between the drive wheel and the processing wheel is so stable that even tissue-backed grinding wheels can be used as processing wheels. Drive disks with grinding disks can then be used in machine tools, eg angle grinders with suitable connecting threads. Obviously, the front part according to the invention is suitable for a variety of grinding and polishing work and therefore represents an ideal solution to the problems at hand.
