Description

Die Erfindung betrifft einen Gehrungsanschlag für Holzbearbeitungsmaschinen mit einem quer zur Vorschubrichtung einer Werkstückaufnahme angeordneten Werkstückanschlag, der um eine zur Werkstückaufnahme lotrechte Achse schwenkbar gelagert und ausgehend von einer Nullstellung in beiden Richtungen schwenkbar ist und der mittels eines abnehmbaren Indexstifts gegenüber der Werkstückaufnahme fixierbar ist, die auf einem Teilkreis um die Schwenkachse des Werkstückanschlags angeordnete, der Nullstellung und anderen bevorzugten Winkelstellungen zugeordnete Indexlöcher aufweist, in die der Indexstift einsteckbar ist.The invention relates to a miter fence for woodworking machines with a workpiece stop arranged transversely to the feed direction of a workpiece holder, which is pivotably mounted about an axis perpendicular to the workpiece holder and can be pivoted in both directions starting from a zero position and which can be fixed relative to the workpiece holder by means of a removable index pin a index circle arranged around the pivot axis of the workpiece stop, the zero position and other preferred angular positions assigned, into which the index pin can be inserted.

Ein Gehrungsanschlag dieser Art ist aus der US-A-1113152 bekannt. Bei dieser bekannten Anordnung ist ein einteiliger Werkstückanschlag vorgesehen, der eine Durchsteckausnehmung für den Indexstift aufweist. Eine Anordnung dieser Art läßt die Herstellung einander gegenüberliegender Gehrungsfugen mit gegenläufigen Neigungen zu. Die bekannte Anordnung gemäß US-A-1 113152 besitzt jedoch keine Möglichkeit zur Justierung des durch den in die zugeordnete Ausnehmung eingreifenden Indexstift gesicherten Werkstückanschlags bezüglich einer Bezugslinie, z.B. bezüglich der Arbeitsebene des Schnittwerkzeugs. Eine hohe Arbeitsgenauigkeit ist hierbei daher nur dann gewährleistet, wenn die Winkellage der Indexlöcher bezüglich der Bezugslinie genau stimmt. Dies ist jedoch auch bei einem hohen Herstellungsaufwand praktisch nicht zu erreichen. Der Grund dafür ist darin zu sehen, daß gewisse Fertigungs- und Montagetoleranzen nicht vermeidbar sind und daß der Einsatzstandort der mit dem Gehrungsanschlag versehenen Maschine von den örtlichen Gegebenheiten her, z.B. der Fundamentbeschaffenheit etc., vom Montagestandort abweicht.A miter stop of this type is known from US-A-1113152. In this known arrangement, a one-piece workpiece stop is provided which has a push-through recess for the index pin. An arrangement of this type allows the production of opposed miter joints with opposite inclinations. However, the known arrangement according to US-A-1 113152 has no possibility of adjusting the workpiece stop secured by the index pin engaging in the associated recess with respect to a reference line, e.g. with respect to the working plane of the cutting tool. A high level of work accuracy is therefore only guaranteed if the angular position of the index holes is correct with respect to the reference line. However, this is practically not achievable even with a high manufacturing cost. The reason for this is that certain manufacturing and assembly tolerances are unavoidable and that the location of the machine provided with the miter fence depends on the local conditions, e.g. the condition of the foundation etc., deviates from the installation site.

Bei der Anordnung gemäß US-A-1 113152 ist der Werkstückanschlag zwar mit einer rückwärtigen Auskragung versehen, die eine Schlitzführung für eine mittels einer Mutter festspannbare Klemmschraube aufweist, die mit einer Durchgangsbohrung zum Durchstecken des Indexstifts versehen ist. Diese Anordnung, die dazu dient, durch Verschieben der Klemmschraube innerhalb der zugeordneten Schlitzführung die Einstellung von Zwischenwinkeln zu ermöglichen, ermöglichte zwar auch eine Justierung der Anschlagkante des Werkstückanschlags bezüglich einer Bezugslinie, z.B. bezüglich der Arbeitsebene des Schnittwerkzeugs. Dies ist jedoch nicht nur in der US-A-1113152 nicht angesprochen, sondern würde auch die Bedienung der bekannten Anordnung sehr erschweren, da die Justierung bei jeder Einstellung eines Zwischenwinkels verloren ginge und daher anschließend neu durchgeführt werden müßte, was einen hohen Zeitaufwand erforderte. Ganz abgesehen davon ist davon auszugehen, daß sich bei der Anordnung gemäß US-A-1 113 152 im Falle einer Justierung der Anschlagkante Abweichungen zwischen der tatsächlichen Stellung der Anschlagkante und dem auf einer zugeordneten Skala angezeigten Wert ergeben könnten.In the arrangement according to US-A-1 113152, the workpiece stop is provided with a rear projection which has a slot guide for a clamping screw which can be tightened by means of a nut and which is provided with a through hole for inserting the index pin. This arrangement, which serves to enable the setting of intermediate angles by displacing the clamping screw within the assigned slot guide, also made it possible to adjust the stop edge of the workpiece stop with respect to a reference line, e.g. with respect to the working plane of the cutting tool. However, this is not only not addressed in US-A-1113152, but would also make operation of the known arrangement very difficult, since the adjustment would be lost with each setting of an intermediate angle and would therefore have to be carried out again afterwards, which took up a lot of time. Quite apart from this, it can be assumed that in the arrangement according to US-A-1 113 152, if the stop edge is adjusted, there could be deviations between the actual position of the stop edge and the value displayed on an assigned scale.

Hiervon ausgehend ist es daher die Aufgabe der vorliegenden Erfindung unter Vermeidung der Nachteile der bekannten Lösung eine Anordnung eingangs erwähnter Art so zu verbessern, daß trotz einer exakten Justierbarkeit der Anschlagkante des Werkstückanschlags bezüglich einer maschinenfesten Bezugslinie eine schnelle Einstellung der Nullstellung und/oder bevorzugter Winkelstellungen mittels des Indexstifts möglich ist.Proceeding from this, it is therefore the object of the present invention, while avoiding the disadvantages of the known solution, to improve an arrangement of the type mentioned in such a way that, despite an exact adjustability of the stop edge of the workpiece stop with respect to a machine-fixed reference line, a quick setting of the zero position and / or preferred angular positions by means of of the index pin is possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Werkstückanschlag eine um die zur Auflagefläche der Werkstückaufnahme lotrechte Achse schwenkbar auf der Werkstückaufnahme gelagerte, eine genaue Passung für den Indexstift aufweisende Indexschiene und eine auf dieser mit Schwenkfreiheitsgrad gegenüber dem Indexstift um eine ebenfalls zur Auflagefläche der Werkstückaufnahme lotrechte Achse schwenkbar gelagerte Anschlagschiene aufweist, deren Schwenkstellung mittels einer Stelleinrichtung gegenüber der Indexschiene einstellbar ist.This object is achieved in that the workpiece stop is mounted on the workpiece holder with an exact fit for the index pin and has an index rail pivotable about the axis perpendicular to the support surface of the workpiece holder and an index rail on this with a degree of freedom of rotation relative to the index pin by a likewise perpendicular to the support surface of the workpiece holder Axis pivotally mounted stop rail, the pivot position of which is adjustable by means of an actuating device relative to the index rail.

Der erfindungsgemäßen Anordnung liegt demnach ein zweiteiliger Werkstückanschlag zugrunde. Die zweiteilige Ausführung des Werkstückanschlags ermöglicht in vorteilhafter Weise bei durch den Indexstift fixierter Indexschiene eine genaue Justierung der gegenüber der Indexschiene schwenkbaren, eine Anschlagkante aufweisenden Anschlagschiene bezüglich einer Bezugslinie, z.B. bezüglich der Vorschubrichtung bzw. der benachbarten Maschinentischseitenkante oder der Arbeitsebene des Schnittwerkzeugs. Bei der Erstanbringung ist eine derartige Justierbarkeit von Vorteil, da sich Herstellungs- und Montagetoleranzen nicht ausschalten lassen und der Aufstellungsort von den lokalen Verhältnissen her in der Regel vom Montagestandort abweicht. Da die Stellung der Indexschiene während der Justierung der Anschlagschiene gegenüber der Werkstückaufnahme in vorteilhafter Weise fixiert bleibt, ist auch sichergestellt, daß sich im Falle einer der Indexschiene zugeordneten, mit einer Winkelteilung versehenen Skala trotz einer möglichen Verschiebung der Winkellage der Anschlagschiene keine Änderung der Lage der der Skala zugeordneten Ablesekante der Indexschiene ergibt, was sich positiv auf die erzielbare Einstellgenauigkeit und Bedienungsfreundlichkeit auswirkt. Hieraus ist erkennbar, daß die Erfindung die ihr gestellte Aufgabe mit einfachen und daher kostengünstigen Mitteln löst.The arrangement according to the invention is therefore based on a two-part workpiece stop. The two-part design of the workpiece stop advantageously enables precise adjustment of the stop rail that can be pivoted relative to the index rail and has a stop edge with respect to a reference line, e.g. with respect to the feed direction or the adjacent side of the machine table or the working plane of the cutting tool. Such an adjustability is advantageous when installing for the first time, since manufacturing and assembly tolerances cannot be eliminated and the installation site generally differs from the assembly site in terms of local conditions. Since the position of the index rail remains fixed in relation to the workpiece holder during the adjustment of the stop rail in an advantageous manner, it is also ensured that in the case of a scale associated with the index rail, provided with an angular division, no change in the position of the stop rail despite a possible shift in the angular position of the stop rail the reading edge of the index rail assigned to the scale results, which has a positive effect on the achievable setting accuracy and user-friendliness. From this it can be seen that the invention solves the task set with simple and therefore inexpensive means.

Eine weitere vorteilhafte Maßnahme kann darin bestehen, daß die Indexschiene und die hierauf gelagerte Stellschiene eine gemeinsame Schwenkachse aufweisen. Diese Maßnahme ergibt eine sehr kompakte Bauweise. Zweckmäßig kann dabei die Indexschiene einen U-förmigen, zur Anschlagschiene hin offenen Querschnitt aufweisen, wobei die Anschlagschiene zwischen die Schenkel der die Indexschiene bildenden U-Schiene eingreifen kann, was eine wackelsichere Aufnahme der Anschlagschiene und damit eine hohe Wiederholungsgenauigkeit ergibt. Zur Bewerkstelligung der gewünschten Justierbarkeit der Anschlagschiene kann diese einfach gegenüber dem spielfrei mit der Indexschiene zusammenwirkenden Indexstift ein entsprechendes Justierungsspiel aufweisen.Another advantageous measure can consist in the fact that the index rail and the adjusting rail mounted thereon have a common pivot axis. This measure results in a very compact design. The index rail can expediently have a U-shaped cross section which is open towards the stop rail, the stop rail being able to engage between the legs of the U rail forming the index rail, which results in a wobble-proof opening taking the stop rail and thus a high repetition accuracy. In order to achieve the desired adjustability of the stop rail, this can simply have an appropriate adjustment play in relation to the index pin interacting with the index rail without play.

In weiterer Fortbildung der übergeordneten Maßnahmen kann zur Justierung der Anschlagschiene eine Stelleinrichtung vorgesehen sein, die mit einer an der Indexschiene und an der Anschlagschiene angreifenden Stellschraube versehen ist, an der die Indexschiene und die Anschlagschiene durch jeweils eine Spannmutter und einen dieser zugeordneten Anschlag fixierbar sind, wobei mindestens einer dieser Anschläge einfach als verstellbare Mutter ausgebildet sein kann. Diese Ausbildung gestattet eine einfache und zuverlässige Justierung der Anschlagschiene sowie eine exakte Festlegung der Anschlagschiene gegenüber der Indexschiene nach erfolgter Fixierung.In a further development of the superordinate measures, an adjusting device can be provided for adjusting the stop rail, which is provided with an adjusting screw engaging on the index rail and on the stop rail, on which the index rail and the stop rail can each be fixed by a clamping nut and an associated stop, wherein at least one of these stops can be designed simply as an adjustable nut. This design allows a simple and reliable adjustment of the stop rail and an exact fixing of the stop rail relative to the index rail after fixation.

Weitere zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der übergeordneten Maßnahmen ergeben sich aus der nachstehenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung in Verbindung mit den restlichen Unteransprüchen.Further expedient refinements and advantageous developments of the superordinate measures result from the following description of an exemplary embodiment with reference to the drawing in conjunction with the remaining subclaims.

In der Zeichnung zeigen:

  • Fig. 1 eine Frontansicht einer mit einem seitlich angebauten, einen Werkstückanschlag aufweisenden Schiebeschlitten versehenen Kreissägentisches,
  • Fig. 2 eine Draufsicht auf den Schiebeschlitten gemäß Fig. 1 und
  • Fig. 3 einen Schnitt entlang der Linie 111/111 in Fig. 2.
The drawing shows:
  • 1 is a front view of a circular saw table provided with a side-mounted sliding carriage having a workpiece stop,
  • Fig. 2 is a plan view of the sliding carriage according to FIGS. 1 and
  • 3 shows a section along the line 111/111 in FIG. 2.

An den in Fig. 1 durch strichpunktierte Linien angedeuteten Kreissägetisch 1 ist eine parallel zur in Vorschubrichtung gesehen linken, zur Sägeblattebenen parallelen Tischkante angeordnete Längsführung 2 angebaut. Hierzu ist die Tischstirnseite mit Anbauplatten 3 versehen, an denen die Längsführung 2 aufnehmende Traglaschen 4 durch Steck- und Klemmverschluß lösbar fixierbar sind. Auf der Längsführung 2 ist ein eine Werkstückaufnahme bildender Schiebeschlitten 5 verschiebbar gelagert. Die Verschiebebewegung ist durch Endanschläge begrenzt, die hier als das die Längsführung 2 bildende Profilrohr durchsetzende Federbolzen 6 ausgebildet sind, die entgegen der Kraft der hieran angreifenden Ausrückfeder zurückgezogen werden können, so daß der Schlitten 5 von der Längsführung 2 abnehmbar ist. Der Schlitten 5 besitzt eine eine Werkstückauflagefläche bildende Tischplatte 7, die mit einem quer zur Vorschubrichtung, d.h. quer zur Längsrichtung der Längsführung 2 angeordneten Werkstückanschlag 8 versehen ist. Der Werkstückanschlag ist zur Durchführung von Gehrungsschnitten um eine zur Auflagefläche der Tischplatte 7 lotrechte Achse a schwenkbar.On the circular saw table 1 indicated by dash-dotted lines in FIG. 1, a longitudinal guide 2 is installed parallel to the left table edge, seen in the feed direction and parallel to the saw blade planes. For this purpose, the table end is provided with mounting plates 3, on which the longitudinal guide 2 receiving support straps 4 can be detachably fixed by means of a plug and clamp lock. A sliding carriage 5, which forms a workpiece holder, is slidably mounted on the longitudinal guide 2. The displacement movement is limited by end stops, which are designed here as the spring bolt 6 passing through the profile tube forming the longitudinal guide 2, which can be withdrawn against the force of the release spring acting thereon, so that the slide 5 can be removed from the longitudinal guide 2. The carriage 5 has a table top 7 which forms a workpiece support surface and which is arranged with a crosswise to the feed direction, i. Workpiece stop 8 arranged transversely to the longitudinal direction of the longitudinal guide 2 is provided. The workpiece stop is pivotable for making miter cuts about an axis a perpendicular to the support surface of the table top 7.

Der Werkstückanschlag 8 ist, wie am besten den Fig. 2 und 3 entnehmbar ist, zweiteilig ausgebildet und besteht aus einer um die Achse a schwenkbar auf der Tischplatte 7 gelagerten Indexschiene 9 und einer auf dieser hier um eine zur Achse a koaxiale Achse schwenkbar gelagerten Anschlagschiene 10. Zur Bildung der Schwenkachsen von Indexschiene 9 und Anschlagschiene 10 ist hierbei einfach ein die Indexschiene 9 und die Anschlagschiene 10 spielfrei durchsetzender und in eine tischplattenseitige Lagerbohrung spielfrei eingreifender Federstift 11 vorgesehen. Die Indexschiene 9 ist, wie am besten aus Fig. 3 erkennbar ist, im Querschnitt U-förmig ausgebildet und so angeordnet, daß ihre parallelen Schenkel 12 die Anschlagschiene 10 über- bzw. untergreifen, was eine ausgezeichnete Wackelfreiheit der Anschlagschiene 10 ergibt. Im dargestellten Ausführungsbeispiel besteht die Anschlagschiene 10 aus einem zwischen die Schenkel 12 der Indexschiene 9 eingreifenden Trägerrohr 13 und einer auf dieses aufgesetzten Verlängerungsleiste 14, die durch Klemmschrauben 15 lösbar hieran festlegbar ist.The workpiece stop 8, as can best be seen in FIGS. 2 and 3, is formed in two parts and consists of an index rail 9 pivotably mounted on the table top 7 about the axis a and a stop rail pivotably mounted on the index rail here about an axis coaxial with the axis a 10. To form the swivel axes of index rail 9 and stop rail 10, a spring pin 11 is simply provided which penetrates the index rail 9 and the stop rail 10 without play and engages in a table-side bearing bore without play. The index rail 9 is, as can be seen best from FIG. 3, U-shaped in cross section and arranged so that its parallel legs 12 overlap or underneath the stop rail 10, which results in excellent wobble freedom of the stop rail 10. In the exemplary embodiment shown, the stop rail 10 consists of a support tube 13 engaging between the legs 12 of the index rail 9 and an extension bar 14 placed thereon, which can be releasably secured thereto by means of clamping screws 15.

Die Schwenkbarkeit des Werkstückanschlags 8 um die Schwenkachse a gestattet die Einstellung jedes gewünschten Gehrungswinkels. Zur Durchführung entsprechender Schnittarbeiten ist der schwenkbare Werkstückanschlag 8 gegenüber der Tischplatte 7 verdrehsicher fixierbar. Hierzu ist, wie den Fig. 1 und 2 entnommen werden kann, eine Spannschraube 16 vorgesehen, die an der Indexschiene 9 angreift und durch eine bogenförmige Längsnut 17 der Tischplatte 7 hindurchgreift. Der Spannschraube 16 ist eine im Bereich der Tischunterseite angeordnete, von Hand betätigbare Spannmutter 18 zugeordnet, mit welcher ein Klemmverschluß erzeugbar ist. Die bogenförmige Nut 17 folgt dem Verlauf eines Kreises um die Achse a mit dem Abstand der Spannschraube 16 von der Achse a entsprechendem Radius. Im dargestellten Ausführungsbeispiel greift die Spannschraube 16 durch die Schenkel 12 der Indexschiene 9 hindurch, so daß diese bei entsprechender Spannkraft an hiervon umfaßten Trägerrohr 13 der Anschlagschiene 10 angepaßt werden. Die Formsteifigkeit der Trägerrohre 13 stellt hierbei sicher, daß die U-förmige Indexschiene unter der Wirkung der Spannkraft nicht verformt wird. Bei gelöster Spannmutter 18 ist jede gewünschte Winkelstellung innerhalb der bogenförmigen Nut 17 einstellbar. Hierzu ist die Tischplatte 7 als Skalenträger für eine eingeformte bzw. aufgeklebte Skala 19 ausgebildet, der eine Einstellkante 20 der Indexschiene zugeordnet ist, wie Fig. 2 zeigt. Zur Bewerkstelligung einer parallaxenfreien Einstellung weist die Einstellkante 20 eine scharfe skalenseitige Kante auf. Im dargestellten Ausführungsbeispiel ist die Indexschiene 9 zur Bildung der Einstellkante 20 einfach im Bereich ihrer Rückseite entsprechend ausgestanzt.The pivotability of the workpiece stop 8 about the pivot axis a allows the setting of any desired miter angle. To carry out corresponding cutting work, the pivotable workpiece stop 8 can be fixed in a rotationally fixed manner relative to the table top 7. For this purpose, as can be seen in FIGS. 1 and 2, a clamping screw 16 is provided which engages the index rail 9 and engages through an arcuate longitudinal groove 17 of the table top 7. The clamping screw 16 is assigned a manually operable clamping nut 18 which is arranged in the region of the underside of the table and by means of which a clamp closure can be produced. The arcuate groove 17 follows the course of a circle around the axis a with the distance of the clamping screw 16 from the axis a corresponding radius. In the illustrated embodiment, the clamping screw 16 extends through the legs 12 of the index rail 9, so that these are adapted to the support rail 13 of the stop rail 10, which is covered by this, with a corresponding clamping force. The rigidity of the support tubes 13 ensures that the U-shaped index rail is not deformed under the action of the clamping force. When the clamping nut 18 is loosened, any desired angular position can be set within the arcuate groove 17. For this purpose, the table top 7 is designed as a scale support for a molded-in or glued-on scale 19, to which an adjustment edge 20 of the index rail is assigned, as shown in FIG. 2. In order to achieve a parallax-free setting, the setting edge 20 has a sharp edge on the scale side. In the exemplary embodiment shown, the index rail 9 is simply punched out in the area of its rear side to form the setting edge 20.

Die Nullstellung des Werkstückanschlags 8, d. h. diejenige Stellung, in der die werkstückseitige Anschlagkante des Werkstückanschlags genau unter einem Winkel von 90 Grad zur Vorschubrichtung des Schlittens 5 bzw. zur Ebene des zugeordneten Sägenblatts bzw. zur sägenplattparallelen Tischkante verläuft, befindet sich im Bereich der Mitte der Skala 19 bzw. der bogenförmigen Nut 17, was eine zweisinnige Auslenkung des Werkstückanschlags, d.h. eine Auslenkung über die Nullstellung sowohl im positiven Sinne als auch im negativen Sinne, ermöglicht. In der genannten Nullstellung ist der Werkstückanschlag mittels eines Indexstifts 21 fixierbar, der lösbar auf der Indexschiene 9 aufnehmbar und in ein zugeordnetes Indexloch 22 der Tischplatte 7 einsteckbar ist. Zur Bewerkstelligung einer einwandfreien Wiederholungsgenauigkeit besteht dabei Spielfreiheit sowohl im Bereich der Indexschiene 9 als auch im Bereich der Tischplatte 7. Im dargestellten Ausführungsbeispiel greift der Indexstift 21, wie am besten aus Fig. 3 erkennbar ist, durch die Schenkel 12 der Indexschiene 9 und durch das von den Schenkeln 12 umfaßte Trägerrohr 13 der Anschlagschiene 10 hindurch. Im Bereich der Schenkel 12 ist hierbei eine genaue Passung vorgesehen. Im Bereich des Trägerrohrs 13 ist dem Indexstift 21 ein bogenförmiger Schlitz 23 zugeordnet, was eine Auslenkung der Anschlagschiene 10 relativ zur Indexschiene 9 ermöglicht. Diese Relativbewegungsmöglichkeit zwischen Indexschiene 9 und Anschlagschiene 10 ist erforderlich, um eine genaue Justierung der werkstückseitigen Anschlagkante in der Nullstellung durchführen zu können. Eine derartige Justierung ist zumindest bei der Neuaufstellung einer Maschine erforderlich, um Ungenauigkeiten, die sich aus den lokalen Verhältnissen des Aufstellungsorts ergeben, auszugleichen.The zero position of the workpiece stop 8, i.e. the position in which the workpiece-side stop edge of the workpiece stop runs exactly at an angle of 90 degrees to the feed direction of the slide 5 or to the plane of the associated saw blade or to the table edge parallel to the saw plate, is in the region of the middle of the Scale 19 or the arcuate groove 17 what a two-sided deflection of the workpiece stop, ie a deflection over the zero position both in the positive sense and in the negative sense. In the aforementioned zero position, the workpiece stop can be fixed by means of an index pin 21, which can be detachably received on the index rail 9 and inserted into an assigned index hole 22 of the table top 7. To achieve a perfect repeat accuracy there is freedom from play both in the area of the index bar 9 and in the area of the table top 7. In the illustrated embodiment, the index pin 21, as can best be seen from FIG. 3, engages through the legs 12 of the index bar 9 and through that Carrier tube 13 of the stop rail 10 encompassed by the legs 12. A precise fit is provided in the region of the legs 12. In the area of the support tube 13, an index-shaped slot 23 is assigned to the index pin 21, which enables a deflection of the stop rail 10 relative to the index rail 9. This possibility of relative movement between the index rail 9 and the stop rail 10 is necessary in order to be able to carry out a precise adjustment of the stop edge on the workpiece in the zero position. Such adjustment is necessary at least when installing a new machine in order to compensate for inaccuracies resulting from the local conditions at the installation site.

Zur Durchführung der Justierung ist eine in Fig. 2 lediglich durch ihre Mittellinie angedeutete Stelleinrichtung 24 vorgesehen, mittels welcher die gegenüber der Indexschiene 9 schwenkbare, hierauf gelagerte Anschlagschiene 10 verstellbar ist. Die Stelleinrichtung 24 besteht hier, wie Fig. 3 zeigt, aus einer an der Anschlagschiene 10, d.h. an deren Trägerrohr 13, und an der Indexschiene 9 angreifenden Spannschraube 25, die sich anschlagschienenseitig mit ihrem Kopf 26 und indexschienenseitig mit einer Stellmutter 27 abstützt. Der durch entsprechende Verdrehung der Stellmutter 27 eingestellte Abstand zwischen Kopf 26 und Stellmutter 27 und damit der zwischen Indexschiene 9 und Anschlagschiene 10 eingestellte Winkel ist durch den Kopf 26 bzw. der Stellmutter 27 zugeordnete Spannmuttern 28 fixierbar, welche die Indexschiene 9 gegen die zugeordnete Stellmutter 27 und das Trägerrohr 13 der Anschlagschiene 10 gegen den zugeordneten Schraubenkopf 26 spannen.To carry out the adjustment, an adjusting device 24, indicated only by its center line, is provided, by means of which the stop rail 10, which is pivotable relative to the index rail 9 and is mounted thereon, can be adjusted. The actuating device 24 here, as shown in FIG. 3, consists of a on the stop rail 10, i.e. on the support tube 13 and on the index rail 9 clamping screw 25 which is supported on the stop rail side with its head 26 and on the index rail side with an adjusting nut 27. The distance between the head 26 and the adjusting nut 27, which is set by a corresponding rotation of the adjusting nut 27, and thus the angle set between the index rail 9 and the stop rail 10, can be fixed by the clamping nuts 28 assigned to the head 26 or the adjusting nut 27, which lock the indexing rail 9 against the assigned adjusting nut 27 and clamp the support tube 13 of the stop rail 10 against the assigned screw head 26.

Im dargestellten Ausführungsbeispiel sind, wie am besten aus Fig. 2 erkennbar ist, zur schnellen Fixierung des Werkstückanschlags in allen wichtigen Winkelstellungen mehrere, auf einem Teilkreis um die Schwenkachse a angeordnete Indexlöcher 22 vorgesehen. Der zur bogenförmigen Nut 17 bzw. zur Skala 19 parallele Teilkreis der Indexlöcher 22 führt in beiden Richtungen über die Nullstellung des Werkstückanschlags hinaus. Die vorgesehenen Indexlöcher 22 können mit gleicher oder ungleicher Teilung angeordnet sein. Im dargestellten Ausführungsbeispiel sind die Indexlöcher mit einer 15 Grad-Teilung angeordnet, wodurch die wichtigen Winkel von 30 Grad und 45 Grad erfaßt werden. In manchen Fällen kann sich auch eine noch feinere Teilung, z. B. eine 5 Grad-Teilung als zweckmäßig erweisen. In diesem Falle können etwa zwei Indexloch-Teilkreise vorgesehen sein, auf denen die Indexlöcher versetzt gegeneinander angeordnet sein können. Die Indexschiene 9 und das Trägerrohr 13 der Anschlagschiene 10 müßten in diesem Fall ebenfalls mit zwei radial gestaffelten Aufnahmen für einen Indexstift 21 versehen sein. Die durch Indexlöcher 22 vorgegebenen Winkelstellungen sind einfach durch Einstecken des Indexstifts 21 festlegbar. Die Spannschraube 16 wird demnach lediglich im Bereich der mit Hilfe der Skala 19 und der Einstellkante 20 einstellbaren Zwischenstellungen benötigt.In the exemplary embodiment shown, as can best be seen from FIG. 2, a plurality of index holes 22 arranged on a pitch circle around the pivot axis a are provided for quickly fixing the workpiece stop in all important angular positions. The partial circle of the index holes 22 parallel to the arcuate groove 17 or to the scale 19 leads in both directions beyond the zero position of the workpiece stop. The index holes 22 provided can be arranged with the same or different pitches. In the illustrated embodiment, the index holes are arranged with a 15 degree division, whereby the important angles of 30 degrees and 45 degrees are detected. In some cases, an even finer division, e.g. B. a 5 degree division can be useful. In this case, approximately two index hole partial circles can be provided, on which the index holes can be arranged offset with respect to one another. In this case, the index rail 9 and the support tube 13 of the stop rail 10 would also have to be provided with two radially staggered receptacles for an index pin 21. The angular positions specified by index holes 22 can be determined simply by inserting the index pin 21. The clamping screw 16 is therefore only required in the range of the intermediate positions which can be set with the aid of the scale 19 and the setting edge 20.

Die Indexlöcher 22 sind im dargestellten Ausführungsbeispiel als einfache Paßbohrungen ausgebildet, denen ein zylindrischer Abschnitt des Indexstifts 21 zugeordnet ist. Es wäre auch denkbar, die Indexlöcher 22 als Konuslöcher auszubilden, denen konische Abschnitte des Indexstifts 21 zugeordnet sind. In einem deratigen Fall wäre sichergestellt, daß der Indexstift 21 stets satt und spielfrei am lochseitigen Sitz zur Anlage kommt. Zur Bewerkstelligung einer einfachen Betätigung des Indexstifts 21 ist dieser mit einem im Bereich seines oberen Endes angeordneten knopfartigen Griff 29 versehen. Im Bereich seines unteren Endes kann eine Einführphase 30 vorgesehen sein, welche das Einführen des Indexstifts 21 in die zugeordneten werkstückanschlagseitigen und tischplattenseitigen Aufnahmen erleichtert.In the exemplary embodiment shown, the index holes 22 are designed as simple fitting bores, to which a cylindrical section of the index pin 21 is assigned. It would also be conceivable to design the index holes 22 as conical holes, to which conical sections of the index pin 21 are assigned. In such a case it would be ensured that the index pin 21 always comes to rest on the hole-side seat in a full and play-free manner. To accomplish a simple actuation of the index pin 21, this is provided with a button-like handle 29 arranged in the region of its upper end. In the area of its lower end, an insertion phase 30 can be provided, which facilitates the insertion of the index pin 21 into the associated receptacles on the workpiece stop and on the table top.
