Description
Vorrichtung zum Bohren und Gewindeschneiden Die Erfindung betrifft eine Vorrichtung für elektrische und andere Handbohrmaschinen zum Ermitteln der Bohrrichtung beim Bohren und Gewindeschneiden.Device for drilling and tapping The invention relates to a device for electric and other hand drills to determine the Drilling direction when drilling and thread cutting.
Die bisher bekannten Vorrichtungen, bestehend aus einer an der Handbohrmaschine festmontierten Wasserwaage oder Libelle, dienen nur zu Bohrungen an Flächen, die waagerecht bzw. senkrecht liegen. Bei schweren und großen Werkstücken läßt sich die Bohrfläche oft nicht ausrichten, wobei die festmontierte Wasserwaage zwecklos ist.The previously known devices, consisting of one on the hand drill Permanently mounted spirit level or spirit level, are only used for drilling on surfaces that lie horizontally or vertically. With heavy and large workpieces Often times do not align the drilling surface, whereby the fixed spirit level is useless is.
Diesem Übelstand abzuhelfen, bezweckt die Erfindung, die ein genaues Einstellen der .Bohrrichtung in jeder Lage ermöglicht.To remedy this disadvantage, the aim of the invention, which is an accurate Adjustment of the drilling direction in every position.
Die neue Vorrichtung besteht aus einer bekannten Dosenlibelle, die mittels eines selbsthemmenden Schneckentriebes nach den erforderlichen Richtungen verdrehbar ist, und einem offenen Lagerring, der die Vorrichtung am Lagerhals der Bohrmaschine festhält und dessen Unterseite bei abgenommener Vorrichtung als Ausrichtfläche dient.The new device consists of a well-known circular level, the by means of a self-locking worm drive in the required directions is rotatable, and an open bearing ring that the device on the bearing neck of the Holds the drill and its underside as an alignment surface when the device is removed serves.
Auf der Zeichnung ist die Vorrichtung in verschiedenen Richtungen beispielsweise dargestellt, und zwar nach Abb. i zum Vertikalbohren, Abb. 2 zum Horizontalbohren, Abb. 3 zum Schräg-zur-Fläche-Bohren. Abb. q. veranschaulicht die Handbohrmaschine mit aufgeschobener Vorrichtung.In the drawing the device is in different directions For example shown, namely according to Fig. i for vertical drilling, Fig. 2 for Horizontal drilling, Fig. 3 for inclined-to-surface drilling. Fig.q. illustrates the Hand drill with attached device.
Soll beispielsweise eine Bohrung vertikal ausgeführt werden, so wird die Vorrichtung nach Abb. i angewendet, indem man den Lagerring a auf die zu bohrende Fläche mit der einen Hand andrückt .und mit der anderen die Dosenlibelle d mittels der Griffe b und c so lange waagerecht einstellt, bis sich die Wasserblase f in der Ringmarke e zentriert. Hernach wird die Vorrichtung nach Abb. q., über .den Lagerhals h der Bohrmaschine geschoben, und zwar in derselben Richtung wie bei der Einstellung.If, for example, a hole is to be drilled vertically, the device according to Fig. I is used by pressing the bearing ring a onto the surface to be drilled with one hand and keeping the circular level d horizontally with the other using the handles b and c adjusts until the water bubble f is centered in the ring mark e. Afterwards, the device is pushed over the bearing neck h of the drill as shown in Fig. Q., In the same direction as during the setting.
Beim Horizontalbohren nach Abb. 2 ist der Vorgang derselbe, jedoch verdreht sich die Dosenlibelle d etwa go° um die Achse g.When drilling horizontally as shown in Fig. 2, the process is the same, however the circular level d rotates about go ° about the axis g.
Handelt es sich um Bohrungen, die schräg zur bohrenden Fläche kommen, nach Abb. 3, so bedient man- sich eines Keiles i, der dem betreffenden Winkel entspricht. Der Keil kann auch verstellbar und mit Gradeinteilung versehen sein.If the holes are drilled at an angle to the surface to be drilled, According to Fig. 3, a wedge i is used which corresponds to the angle in question. The wedge can also be adjustable and graduated.
Die Einstellung der Dosenlibelle. kann auch mittels eines Kugelgelenkes o. dgl. erfolgen, ebenso kann statt eines zylindrischen. Lagerringes die Übertragung des Bohrwinkels durch ein Prisma o. dgl. geschehen.The setting of the circular level. can also be done by means of a ball joint o. The like. Can also be used instead of a cylindrical. Bearing ring the transmission of the drilling angle through a prism or the like. Done.
