Abstract

The invention relates to an adjustable sanding block (3) for sanding a profiled workpiece (10). Said block comprises a group of lamellae (6), arranged in a row next to one another, perpendicular to the sanding direction and forming a profiled sanding surface. The lamellae are mounted in a housing (2) so that they can be displaced in relation to one another perpendicular to the sanding direction and can be clamped in a fixed manner in their respective displaced position by means of a clamping device. The aim of the invention is to provide a sanding block (3), whose contour can be rapidly adapted to the profile shape that is to be sanded and which can be fixed in the exact profile shape that is desired. To achieve this, the group of lamellae (6) can be pushed from an initial position that is restricted by a stop into the housing (2) against a spring resistance and the clamping device subjects the lamellae (6) to a clamping force on their front face, relative to the sanding direction.

Description

Einstellbares SchleifkissenAdjustable sanding pad
Technisches GebietTechnical field
[0001] Die Erfindung bezieht sich auf ein einstellbares Schleifkissen zum Bearbeiten eines profilierten Werkstückes, mit einem eine profilierte Schleifflache bestimmenden Paket aus quer zur Schleifrichtung nebeneinandergereihten, hochkant zur Schleifflache angeordneten Lamellen, die in einem Gehäuse gegeneinander quer zur Schleifrichtung verschiebbar gelagert und mit Hilfe einer Klemmeinrichtung in der jeweiligen Verschiebelage festklemmbar sind.The invention relates to an adjustable sanding pad for machining a profiled workpiece, with a package defining a profiled grinding surface from side by side, arranged side by side, upright to the grinding surface arranged slats, which are mounted in a housing against each other transversely to the grinding direction and with the help of a Clamping device can be clamped in the respective displacement position.
Stand der TechnikState of the art
[0002] Beim manuellen Schleifen wird ein Schleifmittel, insbesondere Schleifpapier, von Hand aus über ein profiliertes Werkstück geführt. Dabei kommen auch entsprechend profilierte Schleifklötze aus Holz oder Kork zum Einsatz, die das Schleifmittel zwischen sich und dem Werkstück aufnehmen. Das Schleifmittel wird entweder von Hand am Schleifklotz gehalten, am Schleifklotz angeklebt oder mit Klammern daran befestigt. Die Herstellung der Schleifklötze ist jedoch sehr zeit- und kostenaufwendig, da für jede mögliche Profilform ein eigener Schleifklotz gefertigt werden muß.In manual grinding, an abrasive, in particular sandpaper, is guided by hand over a profiled workpiece. Correspondingly profiled sanding blocks made of wood or cork are used to hold the abrasive between themselves and the workpiece. The abrasive is either held by hand on the sanding block, glued to the sanding block or fastened to it with clips. However, the production of the sanding blocks is very time-consuming and costly since a separate sanding block has to be made for each possible profile shape.
[0003] Um dies zu vermeiden, ist es bereits bekannt (US 1 570 177 A, DE 38 08 138 A1), Schleifklötze mit gegeneinander verschiebbaren Lamellen vorzusehen, welche Lamellen sich einer profilierten Oberfläche durch Andrücken anpassen und anschließend in dieser angepaßten Stellung durch ein gegenseitiges Spannen fixieren lassen. Durch das gegenseitige Aneinanderpressen der Lamellen entsteht jedoch beim Spannen ein Fehler in der Profilform des Schleifkissens, sodaß die Profilform des Schleifkissens nicht mehr mit der Profilform des Werkstückes überinstimmt.To avoid this, it is already known (US 1 570 177 A, DE 38 08 138 A1) to provide grinding blocks with mutually displaceable lamellae, which lamellae adapt to a profiled surface by pressing and then in this adjusted position by a allow mutual tensioning to be fixed. Due to the mutual pressing of the lamellas, an error occurs in the profile shape of the sanding pad during tensioning, so that the profile shape of the sanding pad no longer corresponds to the profile shape of the workpiece.
[0004] Weiters kommen elektrisch oder pneumatisch betriebene Linearschleifer zum Einsatz, die mit Schleifschuhen vorgegebener Profilform bestückbar sind.Furthermore, electrically or pneumatically operated linear grinders are used, which can be fitted with grinding shoes of a predetermined profile shape.
Darstellung der ErfindungPresentation of the invention
[0005] Der Erfindung liegt die Aufgabe zugrunde, ein Schleifkissen zu schaffen, dessen Kontur sich einerseits rasch auf die zu bearbeitende Profilform einstellen und das sich anderseits exakt in der gewünschten Profilform fixieren läßt, wobei das Schleifkissen genauso zum manuellen wie zum maschinellen schleifen geeignet sein soll. Zudem soll eine schnelle und sichere Befestigungsmöglichkeit für das Schleifmittel am Schleifkissen geschaffen werden.The invention has for its object to provide a sanding pad whose contour on the one hand quickly adjust to the profile shape to be machined and on the other hand can be fixed exactly in the desired profile shape, the sanding pad being suitable for manual as well as for mechanical grinding should. In addition, a quick and safe way of fastening the abrasive to the abrasive pad is to be created.
[0006] Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lamellen des Paketes aus einer anschlagbegrenzten Ausgangsstellung gegen Federkraft in das Gehäuse einschiebbar sind und daß die Klemmeinrichtung die Lamellen in Schleifrichtung stirnseitig mit einer Klemmkraft beaufschlagt. Durch die erfindungsgemäßen Maßnahmen kann die Profilform des Schleifkissens nicht nur rasch und genau an die Profilform des zu fertigenden Werkstückes angepaßt werden, sondern läßt sich das Schleifkissen auch exakt in der gewünschten Profilform fixieren.This object is achieved in that the lamellae of the package can be inserted from a stop-limited starting position against spring force into the housing and that the clamping device acts on the end of the lamellae in the grinding direction with a clamping force. With the measures according to the invention, the profile shape of the grinding pad can not only be adapted quickly and precisely to the profile shape of the workpiece to be manufactured, but the grinding pad can also be fixed exactly in the desired profile shape.
[0007] Um besonders einfache und wirksame konstruktive Verhältnisse zu schaffen, ist das Lamellenpaket auf der der Schleiffläche gegenüberliegenden Seite an einer elastischen Gehäuseeinlage abgestützt und/oder besteht die Klemmeinrichtung aus einer in Schleifrichtung verstellbaren Spannplatte, die in einer Stirnseite des Gehäuses gelagert ist und mit der gegenüberliegenden Stirnseite des Gehäuses als Gegenlager zusammenwirkt. Mit der auf die Stirnseite des Lamellenpaketes wirkenden Spannplatte wird die Lage der einzelnen Lamellen zueinander in der gewünschten Position fixiert. Das Gehäuse weist vorzugsweise Klettverschlüsse zur Befestigung eines die Schleifflache überdek- kenden Schleifmittels auf. Ein zwischen Werkstück und Schleifkissen plaziertes Schleifmittel aus Papier, Leinen od. dgl., schmiegt sich an das Schleifkissen und an das Werkstück, worauf es von Hand aus oder maschinell über das Werkstück bewegt wird.In order to create particularly simple and effective structural relationships, the disk set is supported on the side opposite the grinding surface on an elastic housing insert and / or the clamping device consists of an adjustable clamping plate in the grinding direction, which is mounted in an end face of the housing and with the opposite end of the housing cooperates as a counter bearing. The position of the individual slats relative to one another is fixed in the desired position with the clamping plate acting on the end face of the plate pack. The housing preferably has Velcro fasteners for fastening a covering of the grinding surface. abrasive. An abrasive made of paper, linen or the like placed between the workpiece and the sanding pad nestles against the sanding pad and the workpiece, after which it is moved over the workpiece by hand or by machine.

[0009] Fig. 1 zeigt ein auf ein profiliertes Werkstück 10 angedrücktes Schleifkissen 3 mit an die Profilform des Werkstückes 10 angepaßten Lamellen 6. Das in einem Gehäuse 2, aus den einzelnen, in ungeklemmtem Zustand gegeneinander verschiebbaren Lamellen 6, bestehende Paket, ist in der gewünschten Lage mit einer in einer Mutter 7 geführten Spannschraube 8 klemmbar. Die Mutter 7 wirkt auf eine in Schleifrichtung verstellbare Spannplatte 14, die in einer Stirnseite des Gehäuses 2 gelagert ist, mit der gegenüberliegenden Stirnseite des Gehäuses 2 als Gegenlager zusammenwirkt und die Lamellen 6 zwischen den Anlageflächen 12 und 13 (Fig. 2) klemmt. Ein Schleifmittel 9 ist mittels Klettverschlüssen 5 beidseitig am Gehäuse 2 befestigt.Fig. 1 shows a pressed on a profiled workpiece 10 grinding pad 3 with adapted to the profile shape of the workpiece 10 slats 6. The in a housing 2, from the individual, in the unclamped state mutually displaceable slats 6, existing package is in the desired position with a clamping screw 8 guided in a nut 7. The nut 7 acts on a clamping plate 14 which is adjustable in the grinding direction and which is mounted in one end face of the housing 2, cooperates with the opposite end face of the housing 2 as a counter bearing and clamps the lamellae 6 between the contact surfaces 12 and 13 (FIG. 2). An abrasive 9 is fastened to the housing 2 on both sides by means of Velcro fasteners 5.
[0010] Gemäß Fig. 2 weisen die Lamellen 6 ein Langloch 11 auf, dessen oberes Ende bei nicht geklemmten Lamellen 6 durch ein elastische Material 1 gegen einen Anschlagbolzen 4 gedrückt wird.2, the slats 6 have an elongated hole 11, the upper end of which is pressed by an elastic material 1 against a stop pin 4 when the slats 6 are not clamped.
[0011] Die Einstellung des Schleifkissens 3 erfolgt bei gelöster Spannschraube 8, wobei die zwischen den Anlageflächen 12 und 13 geführten Lamellen 6 von der im Gehäuse 2 eingeschlossenen elastischen Gehäuseeinlage 1 zunächst an den Anschlagbolzen 4 gedrückt und die Lamellen 6 somit in einer Ebene ausge- richtet werden. Denn wird das Schleifkissen 3, vorerst ohne das Schleifmittel 9, auf das Werkstück 10 aufgesetzt und soweit gegen den Widerstand der elastischen Gehäuseeinlage 1 angedrückt, bis es das Werkstückprofil angenommen hat. Nun wird die Spannschraube 8 festgezogen und somit die exakte Profilform fixiert. Anschließend legt man den Schleifkörper 9 über das nunmehr profilierte Lamellenpaket, setzt dieses wieder auf das Werkstück 10 auf und befestigt das Schleifmittel 9 mittels der Klettverschlüsse 5 am Gehäuse 2.[0011] The grinding pad 3 is set when the clamping screw 8 is loosened, the lamellae 6 guided between the contact surfaces 12 and 13 first being pressed against the stop bolt 4 by the elastic housing insert 1 enclosed in the housing 2, and the lamellae 6 thus extended in one plane. be judged. Because the grinding pad 3, initially without the abrasive 9, is placed on the workpiece 10 and pressed against the resistance of the elastic housing insert 1 until it has accepted the workpiece profile. Now the clamping screw 8 is tightened and thus the exact profile shape is fixed. Subsequently, the grinding body 9 is placed over the now profiled disk pack, placed on the workpiece 10 again and the abrasive 9 is fastened to the housing 2 by means of the Velcro fasteners 5.
[0012] Durch ein Andrücken und Hin- und Herbewegen des Schleifkissens 3 in Längsrichtung des profilierten Werkstücks 10 kann das Werkstück 10 manuell oder maschinell geschliffen werden. By pressing and moving the sanding pad 3 in the longitudinal direction of the profiled workpiece 10, the workpiece 10 can be ground manually or by machine.
