Description

DieErfindung betrifft ein Untergestell für eine Handbandschleifmaschine gemäß Oberbegriff von Anspruch 1.The invention relates to a base frame for a hand-held belt grinder according to the preamble of claim 1.

Es ist bekannt, Handbandschleifmaschinen zur stationären Verwendung mit einer Grundplatte zu verbinden und diese am Arbeitstisch festzuklemmen. Das Untergestell bei bekannten Handbandschleifmaschinen kann auch aus einem Winkelgestell bestehen, an dem die Handbandschleifmaschine befestigbar ist und das mit seinen beiden winkelförmig zueinander stehenden Auflageflächen auf einen Arbeitstisch auflegbar ist.It is known to connect hand-held belt grinders for stationary use to a base plate and to clamp them on the work table. The base frame in known hand-held belt grinders can also consist of an angular frame to which the hand-held belt grinder can be fastened and which can be placed on a work table with its two angular support surfaces.

In der ersten Stellung dieses Untergestells verläuft das Schleifband in waagrechter Richtung, in der zweiten Stellung verläuft die Schleifrichtung senkrecht zum Arbeitstisch. In dieser Stellung muß also senkrecht zum Werkstück geschliffen werden, womit nur eine verhältnismäßig geringe Schleifbreite erzielbar ist und somit das Schleifbild beeinträchtigt wird.In the first position of this underframe, the sanding belt runs in a horizontal direction, in the second position the sanding direction runs perpendicular to the work table. In this position, grinding must therefore be carried out perpendicular to the workpiece, with which only a relatively small grinding width can be achieved and the grinding pattern is thus impaired.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Untergestells der eingangs genannten Art, das bei möglichst vielseitiger Verwendung einen einwandfreien Schliff ermöglicht und wirtschaftlich herstellbar ist. Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil von Anspruch 1 angegebenen Merkmale gelöst.The object of the present invention is therefore to create a base frame of the type mentioned at the outset which, with the most versatile possible use, enables a perfect cut and can be produced economically. This object is achieved by the features specified in the characterizing part of claim 1.

Durch die Verwendung einer Grundplatte und einer damit verbindbaren Winkelplatte,jeweils aus Kunststoff-Spritzguß,ergibt sich eine besonders billige Fertigung des Untergestells. Bei der Anklemmung der mit dem Untergestell verbundenen Handbandschleifmaschine an der Grundplatte verläuft das Schleifband waagrecht, so daß die Werkstücke von oben geschliffen werden können.The use of a base plate and an angle plate that can be connected to it, each made of plastic injection molding, results in a particularly cheap manufacture of the underframe. When the hand belt sanding machine connected to the base frame is clamped to the base plate, the sanding belt runs horizontally so that the workpieces can be sanded from above.

Wird das Untergestell jetzt mit der Winkelplatte am Arbeitstisch angeklemmt, so verläuft das Schleifband mit seiner Laufrichtung senkrecht, jedoch mit seiner Laufrichtung parallel zum Arbeitstisch. Dabei sind wieder zwei Anklemmstellungen möglich, in denen zum einen das-Schleifband gegen den Arbeitstisch und zum andern vom Arbeitstisch weggerichtet ist. Im einen Fall lassen sich also plattenförmige Werkstücke von großer Abmessung sicher auf dem Arbeitstisch auflegen und schleifen. Im andern Fall ist ein bequemes Schleifen, von beliebigen Werkstücken außerhalb des Arbeitstisches möglich. Zur Auflage dieser Werkstücke kann vorteilhafterweise der mit der Handbandschleifmaschine verbundene Auflagetisch verwendet werden.If the base frame is now clamped to the work table with the angle plate, the sanding belt runs vertically with its running direction, but with its running direction parallel to the work table. Again, two clamping positions are possible, in which the sanding belt is directed towards the work table and on the other hand away from the work table. In one case, plate-shaped workpieces of large dimensions can be safely placed on the work table and ground. In the other case, it is easy to grind any work piece outside the work table. The support table connected to the hand-held belt grinding machine can advantageously be used to support these workpieces.

Im folgenden ist ein Ausführungsbeispiel der Erfindung unter Bezugnahme auf die Zeichnungen näher beschrieben.An exemplary embodiment of the invention is described in more detail below with reference to the drawings.

Es zeigen:

  • Fig. 1 Untergestell von der Seite, Klemmung mit Grundplatte.
  • Fig. 2 Schnitt nach Linie II - II in Fig. 1.
  • Fig. 3 Untergestell von hinten, Klemmung mit Winkelplatte, Schleifband gegen Arbeitstisch gerichtet.
  • Fig. 4 Untergestell von vorne, Klemmung mit Winkelplatte, Schleifband von Arbeitstisch weggerichtet.
Show it:
  • Fig. 1 base from the side, clamping with base plate.
  • 2 section along line II - II in Fig. 1st
  • Fig. 3 base from behind, clamping with angled plate, sanding belt directed against the work table.
  • Fig. 4 base from the front, clamping with angled plate, sanding belt directed away from the work table.

In Fig. 1 und 2 ist eine Handbandschleifmaschine 1 mit nach oben gerichtetem, waagrecht laufendem Schleifband 2 an einem Untergestell 3 mittels einer Befestigungsschraube 4 abnehmbar befestigt. Das Untergestell 3 besteht aus einer Grundplatte 5, an deren Schmalseite 6 eine Winkelplatte 7 mittels Schrauben 8 abnehmbar befestigt ist.1 and 2, a hand-held belt grinder 1 with an upward, horizontally running grinding belt 2 is removably attached to a base frame 3 by means of a fastening screw 4. The base frame 3 consists of a base plate 5, on the narrow side 6 of which an angle plate 7 is removably fastened by means of screws 8.

Sowohl Grundplatte 5 als auch Winkelplatte 7 weisen Durchgangsbohrungen 9 auf, in die die Haltebügel 10 von Klemmpratzen 11 eingreifen, mit denen das Untergestell 3 an einem Arbeitstisch 12 anklemmbar ist.Both base plate 5 and angle plate 7 have through bores 9 into which the holding brackets 10 of clamping claws 11 engage, with which the base frame 3 can be clamped onto a work table 12.

Damit die Befestigungsschrauben 4 beim Anklemmen der Grundplatte 5 am Arbeitstisch 12 nicht stören, sind ihre Köpfe 13 in Einsenkungen 14 der Grundplatte 5 ,. versenkt angeordnet.So that the fastening screws 4 do not interfere when the base plate 5 is clamped on the work table 12, their heads 13 are in depressions 14 in the base plate 5. arranged sunk.

In den Fig. 1 und 2 ist die Handbandschleifmaschine in bekannter Weise mittels der Grundplatte 5 so am Arbeitstisch 12 festgeklemmt, daß das Schleifband 2 waagrecht und parallel zum Arbeitstisch verläuft und ein Werkstück 15 von oben auf das Schleifband 2 auflegbar ist.1 and 2, the hand belt grinding machine is clamped in a known manner on the work table 12 by means of the base plate 5 in such a way that the grinding belt 2 runs horizontally and parallel to the work table and a workpiece 15 can be placed on the grinding belt 2 from above.

Bei Fig. 3 wird die Winkelplatte 7 am Arbeitstisch 12 so festgeklemmt, daß das Schleifband 2 senkrecht und mit zum Arbeitstisch paralleler Laufrichtung verläuft und dabei gegen den Arbeitstisch gerichtet ist. Somit ist es möglich, unter Verwendung einer Zwischenlage 16 beliebig große plattenförmige Werkstücke 15 auf dem Arbeitstisch aufzulegen und an ihrer Schmalfläche 17 einwandfrei zu schleifen.In Fig. 3, the angle plate 7 is clamped on the work table 12 so that the sanding belt 2 is perpendicular and with the running direction parallel to the work table and is directed against the work table. It is thus possible to place plate-shaped workpieces 15 of any size on the work table using an intermediate layer 16 and to grind them perfectly on their narrow surface 17.

Der Antriebsriemen und der nicht dargestellte Staubsack sind dabei nach oben gerichtet und behindern somit das Anklemmen der Handbandschleifnaschine nicht.The drive belt and the dust bag, not shown, are directed upwards and thus do not hinder the clamping of the hand-held belt grinder.

In einer weiteren Stellung, die in Fig. 4 dargestellt ist, erfolgt das Anklemmen wieder mittels der Winkelplatte 7. Die Grundplatte 5 ist jedoch in dieser Stellung so mit der Winkelplatte 7 verschraubt, daß die Handbandschleifmaschine 1 und damit das Schleifband 2 vom Arbeitstisch 12 weggerichtet sind, wobei Antriebsriemen und Staubsack nach unten zeigen. In diese Stellung läßt sich zusammen mit dem mit der Handbandschleifmaschine 1 verbundenen Auflagetisch 18 eine einwandfreie Führung und damit ein sauberes Schleifen von Werkstücken 15 erzielen.In a further position, which is shown in FIG. 4, the clamping is again carried out by means of the angle plate 7. However, the base plate 5 is screwed to the angle plate 7 in this position in such a way that the hand belt grinding machine 1 and thus the grinding belt 2 are directed away from the work table 12 with the drive belt and dust bag facing down. In this position, together with the support table 18 connected to the hand-held belt grinding machine 1, perfect guidance and thus a clean grinding of workpieces 15 can be achieved.
