Description
Es sind Bohrlehren allgemein bekannt, bei denen die Werkstücke in besonderen Kästen aufgenommen und die Bohrer in geeigneten Hülsen geführt werden. Ihnen gegenüber besteht die Erfindung darin, daß die Führung des Werkzeuges durch in dem Aufnahmekasten verschiebbare, gegeneinander auswechselbare und entsprechend den zu bohrenden Buchstaben und Zahlen gelochte, gehärtete Stahlplatten bewirkt wird.There are drilling jigs well known in which the workpieces in special boxes and the drill bits are guided in suitable sleeves. Against you the invention is that the guide of the tool through in the receiving box Slidable, interchangeable and hardened, perforated according to the letters and numbers to be drilled Steel plates is effected.
Eine beispielsweise Ausführung der Bohrlehre ist in der Zeichnung schematisch dargestellt. Es zeigen:An example embodiment of the drilling jig is shown schematically in the drawing. Show it:
Fig, ι eine Vorderansicht der Bohrlehre, Fig. 2 eine Seitenansicht dazu, Fig. 3 eine Aufsicht auf die fertig eingestellte Lehre undFig, ι a front view of the drilling jig, FIG. 2 shows a side view of this, FIG. 3 shows a plan view of the fully set Teaching and
Fig. 4 eine Aufsicht auf zwei der einschiebbaren Platten, wie diese mit vorgeschriebenen Abmessungen aussehen müssen.Fig. 4 is a plan view of two of the retractable plates, such as these with prescribed Dimensions must look like.
In einen aus Winkeleisen> α bestehenden Rahmen wird die zu lochende Platte b in der beispielsweisen Ausführung als Erkennungsschild für Kraftwagen eingelegt. Über diese Platte b werden die aus Stahl bestehenden, mit in den amtlichen Abmessungsvorschriften ausgeführten Buchstaben- oder Zahlenzeichen versehenen Bbhrlehrenplatten- c bis zu dem Anschlage d in der gewünschten Reihenfolge eingeschoben. Die Breiten der Platten c sind gleich groß und ergeben aneinandergesohoben genau den gesetzlich vorgeschriebenen Abstand von 20 mm von der hinteren, äußersten Kante des ersten Zeichens bis zur vordersten, äußersten Kante des zweiten Zeichens usw. Nach Einbringung der gesamten, gleichzeitig erforderlichen Bohrlehrenplatten c für die gewünschte Beschriftung wird mittels der unter Spannung der Schraubenfedern f stehenden Flügelmutterbolzen g die vordere Festklemmschiene h fest angezogen und daJnn. die hintere, mit Scharnieren i am Rahmen α befestigte Festklemmschiene k mittels der beiden Exzenterhebel ι angezogen.In a frame consisting of angle iron> α , the plate b to be perforated is inserted in the exemplary embodiment as an identification plate for motor vehicles. The Bbhrlehrenplatten- c , which are made of steel and are provided with letters or numbers in the official dimensional regulations, are inserted over this plate b up to the stop d in the desired sequence. The widths of the plates c are the same size and, when stacked together, exactly result in the legally prescribed distance of 20 mm from the rear, outermost edge of the first character to the foremost, outermost edge of the second character, etc. desired inscription is tightened by means of the wing nut bolts g, which are under tension from the helical springs f , the front clamping rail h and then. the rear clamping rail k attached to the frame α with hinges i tightened by means of the two eccentric levers ι.
Bei dieser Anordnung der gesamten Bohrlehrenplatten c für die Beschriftung muß selbst der Unbeholfenste zwangläufig die in der Mitte der Zeichen anzubringenden Löcher m schnellstens genau fertigstellen können.With this arrangement of the entire drilling jig plates c for the lettering, even the most clumsy must inevitably be able to finish the holes m to be made in the center of the characters as quickly as possible.
