Description

Die Erfindung betrifft eine Sägevorrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sawing device according to the preamble of the claim 1.

Sägevorrichtungen der in Rede stehenden Art weisen einen Sägetisch auf, der in der Regel stabil ausgestaltet ist und das Grundgestell der Sägevorrichtung bildet (DE 40 10 456 C2). Der Sägetisch weist üblicherweise eine Werkstückauflagefläche auf, auf der das zu bearbeitende Werkstück aufliegt.Sawing devices of the type in question have a saw table, which in the rule is designed to be stable and forms the base frame of the sawing device (DE 40 10 456 C2). The saw table usually has a workpiece support surface on which the workpiece to be machined rests.

Den meisten bekannten Ausführungsvarianten einer Sägevorrichtung ist gemeinsam, daß ein zu bearbeitendes Werkstück an einem Anschlag, der über eine Befestigungsvorrichtung mit dem Sägetisch verbunden ist, in Anlage kommt. Je nach Ausgestaltung der Sägevorrichtung sind auch mehrere Anschläge vorgesehen, die dann die Ausrichtung des Werkstücks gemeinsam gewährleisten.Most known variants of a sawing device are common, that a workpiece to be machined on a stop, via a fastening device connected to the saw table, comes into contact. ever after design of the sawing device, several stops are provided, which then ensure the alignment of the workpiece together.

Die Maßgenauigkeit des Anschlags selbst sowie die Lage des Anschlags bestimmen wesentlich die Sägegenauigkeit. Aus diesem Grund wird dort, wo es auf Genauigkeit ankommt, eine Möglichkeit zur Feinpositionierung des Anschlags vorgesehen, um die entstehenden Ungenauigkeiten ausgleichen zu können.The dimensional accuracy of the stop itself and the position of the stop significantly determine the sawing accuracy. That's why it gets where it is accuracy is important, a possibility for fine positioning of the stop provided to compensate for the resulting inaccuracies can.

Für eine derartige Feinpositionierung des Anschlags ist bei der Sägevorrichtung, von der die Erfindung ausgeht, der Anschlag verschiebbar gestaltet, so daß er im gelösten Zustand ggf. mit Hilfe einer Meßskala ausgerichtet werden kann (US 2,372,699 A). Nach dem Ausrichten wird der Anschlag dann durch Anziehen von Schraubverbindungen, die durch Langlöcher hindurchgreifen, auf dem Sägetisch fixiert.For such a fine positioning of the stop is in the sawing device, from the invention proceeds, designed the stop displaceable, so that he in dissolved state can be aligned if necessary by means of a measuring scale (US 2,372,699 A). After alignment, the stop is then tightened screw connections passing through slots on the saw table fixed.

Je nach Werkstück und je nach Sägeauftrag sind ggf. unterschiedliche Anschläge erforderlich. Die Anschläge können dabei in ihren Abmessungen, ihrer Form oder in ihrer konstruktiven Ausgestaltung voneinander abweichen. Um wenigstens den Aufwand für den Austausch der Anschläge gering zu halten, weist eine weitere bekannte Sägevorrichtung austauschbare Anschläge auf, die mit Befestigungsklammern auf die eigentlichen Anschläge, die am Sägetisch fixiert sind, aufsteckbar sind (DE 90 03 773 U 1).Depending on the workpiece and the sawing job, different stops may be necessary required. The attacks can be in their dimensions, their shape or differ in their structural design. At least the effort for the replacement of the attacks to keep low, has a other known sawing device exchangeable stops on, which with mounting brackets on the actual stops, which are fixed on the saw table, can be plugged (DE 90 03 773 U 1).

Im Ergebnis besteht ein Widerspruch zwischen der Flexibilität des Anschlags und dessen Genauigkeit. Mit der Austauschbarkeit der Anschläge ist die Feinpositionierung des Anschlags bei jedem Wechsel mit beträchtlichem Aufwand verbunden oder entfällt eben ganz.As a result, there is a contradiction between the flexibility of the attack and its accuracy. With the interchangeability of the stops is the fine positioning of attack with every change associated with considerable effort or completely eliminated.

Bei einer weiteren Sägevorrichtung, die speziell für die Durchführung von Gehrungsschnitten vorgesehen ist, ist der Anschlag am Sägetisch nur in einer festgelegten Position montierbar (US 5,816,129 A). Der Anschlag weist gegenüber einem Anschlaggrundkörper verschiebbare und schwenkbare Anschlagschienen auf.In another sawing device, especially for the implementation of miter cuts is provided, the stop on the saw table is only in a fixed Position mountable (US 5,816,129 A). The stop faces one Stop body slidable and swiveling stop rails on.

Der Erfindung liegt das Problem zugrunde, die bekannte Sägevorrichtung derart auszugestalten und weiterzubilden, daß die Austauschbarkeit der Anschläge bei konstanter Fertigungsgenauigkeit ohne erheblichen Arbeitsaufwand gegeben ist.The invention is based on the problem, the known sawing device such to design and develop that the interchangeability of the attacks in Constant manufacturing accuracy is given without considerable effort.

Die vorliegende Problemstellung wird durch eine Sägevorrichtung mit den Merkmalen des Oberbegriffs von Anspruch 1 durch die Merkmale des kennzeichnenden Teils von Anspruch 1 gelöst.The present problem is solved by a sawing device with the Features of the preamble of claim 1 by the features of the characterizing Part of claim 1 solved.

Wesentlich ist, daß eine einstellbare Justiervorrichtung zur Feinpositionierung des Anschlags am Sägetisch vorgesehen ist, die ihre Einstellung bei der Demontage und der Montage des Anschlags beibehält. Eine derartig ausgestaltete Justiervorrichtung hat den Vorteil, daß bei der Demontage und anschließenden Montage, oder aber beim Wechsel des Anschlags keine erneute Feinpositionierung erforderlich ist. Durch die Anordnung der Justiervorrichtung am Anschlag selbst wird erreicht, daß die zum jeweiligen Anschlag gehörige Einstellung der Justiervorrichtung bei der Demontage des Anschlags "mitgenommen" wird.It is essential that an adjustable adjusting device for fine positioning the stop is provided on the saw table, their setting during disassembly and the mounting of the stop retains. Such an adjusting device configured has the advantage that during disassembly and subsequent Mounting, or when changing the stop no re-fine positioning is required. By the arrangement of the adjusting device on the stop Even it is achieved that the belonging to the respective stop setting the Adjustment device when removing the stop "taken" is.

In besonders bevorzugter Ausgestaltung ist die Justiervorrichtung getrennt von einer Befestigungsvorrichtung des Anschlags am Anschlag selbst angeordnet. Mit der Trennung zwischen Justiervorrichtung und Befestigungsvorrichtung wird erreicht, daß bei der Befestigung aufzuwendende Kräfte sich nicht auf die Einstillung der Justiervorrichtung auswirken.In a particularly preferred embodiment, the adjusting device is separated from a fastening device of the stop on the stop itself arranged. With the separation between the adjusting device and fastening device is achieved that expended in the attachment forces are not on the Einstillung affect the adjusting device.

Der Anschlag 4 ist durch eine Befestigungsvorrichtung 9 mit dem Sägetisch 1 lösbar verbunden. Die Befestigungsvorrichtung 9 ist im Ausführungsbeispiel nach Fig. 1 als Schraubverbindung realisiert, wobei die Schraubverbindung anschlagseitig ein Langloch aufweist. Dieses Langloch weist gerade soviel Spiel auf, daß eine Feinpositionierung des Anschlags 4 möglich ist.The stop 4 is connected by a fastening device 9 with the saw table. 1 releasably connected. The fastening device 9 is in the embodiment 1 realized as a screw, wherein the screw connection stop side has a slot. This slot has just enough game on that a fine positioning of the stopper 4 is possible.

Zur Durchführung der Feinpositionierung ist eine Justiervorrichtung 10 vorgesehen, die getrennt von der Befestigungsvorrichtung 9 ausgestaltet ist. Der besondere Vorteil dieser getrennten Ausgestaltung von Befestigungsvorrichtung 9 und Justiervorrichtung 10 besteht darin, daß das kraftaufwendige Betätigen der Befestigungsvorrichtung 9 die Einstellung der Justiervorrichtung 10 nicht beeinflußt. In bevorzugter Ausgestaltung ist die Justiervorrichtung 10 am Anschlag 4 angeordnet. Es kann aber auch vorgesehen werden, daß die Justiervorrichtung 10 am Sägetisch 1 vorgesehen ist, dann allerdings muß in Kauf genommen werden, daß nur eine einzige Einstellung der Justiervorrichtung 10 für alle eingewechselten Anschläge 4 möglich ist.To carry out the fine positioning, an adjusting device 10 is provided, which is configured separately from the fastening device 9. The special Advantage of this separate embodiment of fastening device 9 and Adjusting device 10 is that the powerful operation of the fastening device 9, the adjustment of the adjusting device 10 is not affected.

But it can also be provided that the adjusting device 10 on Saw table 1 is provided, then, however, must be accepted that only a single adjustment of the adjusting device 10 for all substitutes Stops 4 is possible.

In besonders bevorzugter Ausgestaltung der Lehre der Erfindung weist die Justiervorrichtung 10 mindestens eine Einstellschraube 11 auf, die in eine im Anschlag 4 angeordnete Gewindebohrung eingeschraubt ist. Fig. 2 zeigt, wie das in der Zeichnung rechte Ende der Einstellschraube 11 in Anlage an dem Sägetisch 1 kommt, so daß bei montiertem Anschlag 4 die Feinpositionierung des Anschlags 4 in der Ebene der Werkstückauflagefläche 2 möglich ist.In a particularly preferred embodiment of the teaching of the invention, the adjusting device 10 at least one adjusting screw 11, which in a stop 4 arranged threaded hole is screwed. Fig. 2 shows how the in the drawing right end of the adjusting screw 11 in contact with the saw table. 1 comes so that when mounted stop 4, the fine positioning of the stop 4 in the plane of the workpiece support surface 2 is possible.

Je nach Befestigungsvorrichtung 9 kann es vorgesehen sein, daß der Einstellschraube 11 eine tragende Funktion zukommt, daß also Kräfte über die Einstellschraube 11 übertragen werden oder daß die Einstellschraube 11 lediglich derart in Anlage an dem Sägetisch 1 kommt, daß sie bei befestigtem Anschlag 4 im wesentlichen frei von Kräften ist.Depending on the fastening device 9, it may be provided that the adjusting screw 11 has a supporting function, so that forces on the adjusting screw 11 are transmitted or that the adjusting screw 11 only in such a way comes in contact with the saw table 1 that they are at fixed stop 4 substantially is free from forces.

Fig. 3 zeigt den Anschlag 4 der erfindungsgemäßen Sägevorrichtung in perspektivischer Ansicht. Für die Justiervorrichtung 10 sind hier zwei Einstellschrauben 11 vorgesehen, die jeweils an einer Endseite des Anschlags 4 angeordnet sind (in Fig. 3 sind lediglich die Gewindebohrungen zu erkennen). Mit dieser beidseitigen Anordnung der Einstellschrauben 11 ist eine optimale Feinpositionierung über die gesamte Länge des Anschlags 4 gegeben. In einfacher Ausgestaltung kann es aber auch vorgesehen sein, daß nur eine Einstellschraube 11 vorgesehen ist, die vorzugsweise an einem der beiden Endseiten des Anschlags 4 angeordnet ist.Fig. 3 shows the stop 4 of the sawing device according to the invention in perspective View. For the adjustment device 10 here are two screws 11 are provided, which are each arranged on one end side of the stopper 4 (in Fig. 3, only the threaded holes can be seen). With this two-sided Arrangement of the adjusting screws 11 is an optimal fine positioning given over the entire length of the attack 4. In a simple embodiment but it can also be provided that only one adjusting screw 11 is provided is, which is preferably arranged on one of the two end sides of the stopper 4 is.

Weiter ist es in besonders bevorzugter Ausgestaltung vorgesehen, daß die Einstellschraube 11 selbsthemmend ausgestaltet ist, oder daß die Einstellschraube 11 mit einer entsprechenden Kontermutter versehen ist. Insbesondere vor dem Hintergrund, daß die Einstellung der Justiervorrichtung 10 bei der Demontage und anschließenden Montage des Anschlags 4 beibehalten werden soll, ist dies besonders vorteilhaft.Further, it is provided in a particularly preferred embodiment, that the adjusting screw 11 is designed to be self-locking, or that the adjusting screw 11 provided with a corresponding lock nut. Especially against the background, that the adjustment of the adjusting device 10 during disassembly and subsequent installation of the stop 4 is to be maintained, this is special advantageous.

Wie bereits erläutert wurde, ist im Ausführungsbeispiel nach Fig. 1 eine Feinpositionierung des Anschlags 4 im wesentlichen in der Ebene der Werkstückauflagefläche 2 des Sägetischs 1 durchführbar. Es ist aber auch denkbar, daß je nach Ausgestaltung der Justiervorrichtung 10 und entsprechender Anordnung der Einstellschraube 11 eine Feinpositionierung in anderen Vorzugsrichtungen realisierbar ist.As already explained, in the embodiment of FIG. 1 is a fine positioning the stop 4 substantially in the plane of the workpiece support surface 2 of the saw table 1 feasible.
