Description
Die Erfindung betrifft eine Vorrichtung zum Ausrichten und Feststellen eines Spaltkeils an dem Tisch einer Kreissäge, um Unglücksfälle zu verhüten.The invention relates to a device for aligning and locking a riving knife on the table of a circular saw to prevent accidents.
Schutzvorrichtungen an Kreissägen sind schon bekannt, doch sind diese in Form von Spaltkeilen ausnahmslos nur von unten, unter dem Kreissägentisch zu verstellen, was sehr umständlich und unbequem ist. Auch ist die genaue Einstellung in Richtung der Säge oft nur schwer möglich. Durch ungenaues Einrichten des Spaltkeils ist es möglich, daß die Kreissäge den Spaltkeil erfaßt und herausschleudert.Protective devices on circular saws are already known, but these are in the form of riving knife only from below, under the circular saw table adjust, which is very cumbersome and inconvenient. Also is the exact setting in the direction of the saw is often difficult to do. Due to inaccurate setting up of the riving knife it is possible that the circular saw catches the riving knife and throws it out.
Nach der Erfindung ist nun in der Platte des Kreissägetisches eine Ausnehmung vorgesehen, in welcher eine Klemmvorrichtung, bestehend aus zwei Klemmplatten, eingebaut ist, zwischen denen ein Befestigungswinkel des Spaltkeils verschiebbar und drehbar mittels einer von oben anziehbaren Schraube einspannbar ist. Dadurch ist es möglich, die richtige Einstellung undAusrichtung des Spaltkeils zur Kreissäge von oben aus auf einfache Weise vorzunehmen, da der zwischen den Klemmplatten eingespannte Schenkel des Befestigungswinkels in der Ebene des Tisches nach zwei Richtungen verschiebbar und drehbar ist.According to the invention, one is now in the plate of the circular saw table Recess provided in which a clamping device consisting of two clamping plates, is installed, between which a mounting bracket of the riving knife can be displaced and is rotatably clamped by means of a screw that can be tightened from above. Through this it is possible to have the correct setting and alignment of the riving knife to the circular saw to be carried out from above in a simple manner, since the clamped between the clamping plates Legs of the mounting bracket can be moved in two directions in the plane of the table and is rotatable.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Abb. i die Schutzvorrichtung mit gehobener Haube, Abb. 2 in betriebsfertigem Zustand, Abb. 3 eine Tischansicht von oben. Abb. 4 einen vertikalen Schnitt.An exemplary embodiment of the invention is shown in the drawing. Fig. I shows the protective device with the hood raised, Fig. 2 ready for use State, Fig. 3 a table view from above. Fig. 4 is a vertical section.
Die Schutzvorrichtung besteht aus einem nach oben verstärkten Spaltkeil i, welcher dem Durchmesser des Kreissägeblattes angepaßt ist und dieses überdeckt bzw. bei größeren Ausführungsformen eine das Sägeblatt umgebende Haube trägt. Der Spaltkeil ist unterhalb der Tischplatte nach allen Richtungen verstellbar angeordnet. Er ist in seinem unteren Teil mit einem Winkelhalter :2 schwenkbar und in jeder Lage fixierbar verbunden, wobei der horizontale Schenkel des Winkelhalters 2 in einer Ausnehmung des Kreissägetisches zwischen zwei Klemmplatten 3 und q. fixierbar ist:. Die beiden Klemmplatten können von. der Oberseite des Tisches mittels einer Schraube 5 angezogen werden und halten damit über den Winkelhalter :2 den Spaltkeil in jeder beliebigen Stellung fest. Der Spaltkeil besitzt an seinem in den Tisch einstehenden Teil einen Schlitz g, in welchen ein mit Handgriff 6 anziehbarer Bolzen 7 liegt. Beidseitig .des Spaltkeils sind Platten 8 angeordnet. Der Schraubbolzen 7, welcher sein Gegengewinde in einer Mutter io findet, die mit dem Winkelhalter :2 verbunden sein kann, fixiert beim Anziehen den Spaltkeil i zwischen den beiden Platten 8 gegen den Winkelhalter 2, so daß er fest gegen den Tisch in der gewünschten Stellung steht. Infolge -der Schlitzführung g kann dabei die Höheneinstellung und der Schwenkwinkel in der Sägeblattebene beliebig variiert werden. Eine Verstellung des Spaltkeils gegen die Sägeblattebene bzw. eine parallele Justierung erfolgt durch die Einspannung des horizontalen Schenkels des Winkelhalters 2 zwischen den Klemmplatten 3 und ¢ mittels der Schraube 5.The protective device consists of a riving knife reinforced at the top i, which is adapted to the diameter of the circular saw blade and covers it or in larger embodiments carries a hood surrounding the saw blade. Of the Riving knife is arranged below the table top so that it can be adjusted in all directions. It is in its lower part with an angle bracket: 2 swiveling and in each Position fixably connected, the horizontal leg of the angle bracket 2 in a recess of the circular saw table between two clamping plates 3 and q. fixable is:. The two clamping plates can from. the top of the table by means of a Screw 5 must be tightened and thus hold the riving knife via the angle bracket: 2 in any position. The riving knife has his in the table standing part a slot g, in which a tightenable with handle 6 bolt 7 lies. Plates 8 are arranged on both sides of the riving knife. The bolt 7, which finds its mating thread in a nut io that goes with the angle bracket : 2 can be connected, fixes the riving knife i between the two when tightened Plates 8 against the angle bracket 2 so that it is firmly against the table in the desired Position. As a result of the slot guide g the height adjustment and the swivel angle in the saw blade plane can be varied as required. An adjustment of the riving knife against the plane of the saw blade or a parallel adjustment is carried out the clamping of the horizontal leg of the angle bracket 2 between the clamping plates 3 and ¢ using the screw 5.
