Description
Die Erfindung betrifft eine Weiterentwicklung einer Vorrichtung zum Halten des Spaltkeiles einer Kreissäge gemäß dem Patent gio 835. Das Hauptpatent betrifft eine Einrichtung, die es gestattet, bei feststehendem Tisch den Spaltkeil in jeder beliebigen Lage zu fixieren.The invention relates to a further development of a device for Holding the riving knife of a circular saw according to patent gio 835. The main patent relates to a device that allows the riving knife to be used when the table is stationary to be fixed in any position.
Die Erfindung beinhaltet die gleiche Aufgabenstellung und betrifft eine konstruktive Eigenart, die es gestattet, die gleiche Fixierung des Spaltkeiles in jeder Stellung auch bei solchen Kreissägen anwenden zu können, die einen hoch- und tiefverstellbaren und schräg anstellbaren Tisch besitzen.The invention includes and relates to the same objectives a structural peculiarity that allows the same fixing of the riving knife to be able to use it in any position even with such circular saws that have a highly and have a deep-adjustable and inclined table.
Während bei der Ausführungsform gemäß dem Hauptpatent die Klemmplatten, welche den Spaltkeil mittels eines Befestigungswinkels tragen, in der Tischplatte angeordnet sind, sind diese Befestigungsmittel bei der vorliegenden Erfindung in einem Gehäuse angebracht, welches unabhängig vom Tisch angeordnet ist. Während die in dem Hauptpatent geschützte Ausführungsform lediglich für Kreissägen mit feststehendem Tisch angewendet werden kann, ist die Ausführungsform gemäß der vorliegenden Erfindung sowohl für Kreissägen mit feststehendem Tisch als auch für solche mit höhen- und schräg verstellbarem Tisch anwendbar.While in the embodiment according to the main patent, the clamping plates, which carry the riving knife by means of a mounting bracket in the table top are arranged, these fastening means are in the present invention in attached to a housing which is arranged independently of the table. While the Protected in the main patent embodiment only for circular saws with fixed Table can be applied is the embodiment according to the present invention for circular saws with a fixed table as well as for those with height and inclined adjustable table applicable.
In den Zeichnungen ist die Erfindung beispielsweise dargestellt, und zwar zeigt Abb. i eine Klemmvorrichtung, unterhalb des Kreissägentisches angebracht, mit Befestigungswinkel und Spaltkeil, bei welcher der Griff der Klemmvorrichtung im Winkel zum Griff des Befestigungsstückes des Spaltkeiles steht und bei welcher die untere bewegliche Platte mittels zweier schräger Flächen bewegt wird, Abb.2 die Form eines Befestigungsstückes für den Spaltkeil mit den einzelnen Teilen.In the drawings, the invention is shown by way of example, and although Fig. i shows a clamping device attached below the circular saw table, with mounting bracket and riving knife, in which the handle of the clamping device is at an angle to the handle of the fastening piece of the riving knife and at which the lower movable plate is moved by means of two inclined surfaces, Fig.2 the shape of a fastening piece for the riving knife with the individual parts.
Bei Kreissägen mit verstellbarem Tisch sind die beiden Klemmplatten in einem Gehäuse angebracht, in welchem die untere, bewegliche und mit einer oder mehreren schrägen Flächen versehene Platte i mittels einer oder mehrerer entgegengesetzter schräger Flächen 2 durch Handrad und Spindel 3 gegen die obere, im Gehäuse befestigte Platte :I bewegt wird und so den Befestigungswinkel 5 des Spaltkeiles 6 festklemmt.For circular saws with an adjustable table, the two clamping plates are mounted in a housing in which the lower, movable and with an or several inclined surfaces provided plate i by means of one or more opposite inclined surfaces 2 by handwheel and spindle 3 against the upper, fixed in the housing Plate: I is moved and thus clamps the mounting bracket 5 of the riving knife 6.
Im Befestigungswinkel greift der Riegel ? mit seinen Nasen 8 und 9 in die Platte io. Die Beweglichkeit des Riegels ist durch die Schlitze i i der Platte begrenzt. Die Nasen greifen durch die Schlitze der Platte in die Aussparung 12 der Auflegeplatte 13, wobei die verlängerte Nase 9 in die Öffnung 1,. der Auflegeplatte greift, um ein Umkippen der Auflegeplatte zu verhindern. Der Spaltkeil greift mit seinem unteren Schlitz durch die beiden Nasen und wird zwischen der Platte und der Auflegeplatte eingeschoben und mittels des Handrades 15 und eines Bolzens festgezogen, wobei der Bolzen durch den Schlitz 16 des Winkels 5, den Riegel 7, die Platte io und die Auflegeplatte 13 greift. Da die Breite der Nasen 8 und 9 des Riegels 7 der Breite des Schlitzes des Spaltkeiles genau angepaßt ist, kann sich der Spaltkeil nach Einstellung und Festziehen auch bei plötzlichem Stoß nicht mehr verstellen. Ausbuchtungen 17 am unteren Teile des Spaltkeiles verhindern ein Herausschleudern eines von der Kreissäge etwa erfaßten Spaltkeiles.Does the bolt engage in the mounting bracket? with its noses 8 and 9 in the plate io. The mobility of the bolt is through the slots i i of the plate limited. The lugs engage through the slots in the plate in the recess 12 of the Support plate 13, the elongated nose 9 in the opening 1 ,. the support plate engages to prevent the support plate from tipping over. The riving knife engages with its lower slot through the two lugs and is between the plate and the Support plate pushed in and tightened by means of handwheel 15 and a bolt, the bolt through the slot 16 of the angle 5, the bolt 7, the plate io and the support plate 13 engages. Since the width of the lugs 8 and 9 of the bolt 7 of the Width of the slot of the riving knife is precisely matched, the riving knife can Do not adjust after setting and tightening, even if there is a sudden impact. Bulges 17 on the lower part of the riving knife prevent it from being thrown out a riving knife detected by the circular saw.
