Description
Die Erfindung betrifft eine tragbare Bohrmaschine für allgemeine Verwendung bei leichteren Arbeiten auf Montage. Die Neuerung ist aus dem Gedanken entstanden, auf Montage in allen erdenklichen Lagen eine leichte, im Werkzeugkoffer wenig Raum beanspruchende Maschine zur Hand zu haben., die, wenn elektrischer Anschluß vorhanden ist, sofort als elektrische HandbohrmaschineThe invention relates to a portable drill for general use in easier work on assembly. The innovation arose from the thought on Installation in all conceivable positions is easy and takes up little space in the tool case Machine to hand. Which, if electrical connection is available is immediately available as an electric hand drill
ίο betriebsbereit ist, und die andererseits, sofern an der Arbeitsstelle keine elektrische; Kraft zur Verfügung steht, als Handbohr* maschine mit Kurbelantrieb Verwendung findet. Bemerkt wird noch, daß es bei Bohrmaschinen an sich bekannt ist, den Antrieb von Hand oder maschinell zu bewirken.ίο is operational, and the other, if no electrical at the workplace; Force is available, as a hand drill * machine with crank drive is used. It should also be noted that it is the case with drilling machines is known per se to effect the drive by hand or by machine.
Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment is shown in the drawing of the invention shown.
Abb. ι stellt die Maschine im Längsschnitt, Abb. 2 in Ansicht und Abb. 3 in einem Querschnitt dar.Fig. Ι shows the machine in longitudinal section, Fig. 2 in a view and Fig. 3 in a cross section represent.
Die Maschine ist hauptsächlich aus zwei j Teilen zusammengesetzt. Der obere Teil des Motorgehäuses enthält einen Einphasen-Kollektormotor mit Serienschaltung zum wahlweisen Anschluß an Gleich- und Wechselstrom mit abhebbaren Bürsten, die durch eine von außen zu bedienenide Vorrichtung (in der Zeichnung nicht enthalten) abgehoben werden. Der untere Teil, das Getriebegehäuse, enthält die Hauptbohrspindel 1 mit Morsekonus und Drucklager. Sie ist getrennt vonThe machine is mainly composed of two parts. The upper part of the Motor housing contains a single-phase collector motor with series connection for optional Connection to direct and alternating current with liftable brushes, which are operated by a device to be operated from the outside (not included in the drawing). The lower part, the gear case, contains the main drilling spindle 1 with Morse taper and thrust bearing. She is separate from

der Motorwelle gelagert und erhält ihren Antrieb durch Stirnradübersetzung 3 im Verhältnis ι: 3 von der Vorgelegewelle 2, welche zur Aufnahme von Werkzeugen ebenfalls mit Morsekonus und Drucklager ausgerüstet ist. Das Vorgelege erhält seinen Antrieb durch Stirnradübersetzung 4 von der MotorweUe. Wie die Abb. 1 und 3 zeigen, wirken auf Hauptbohrspindel 1 und Vorgelegewelle 2 je ein Kegelrädergetriebe f>, 6 mit Übersetzung ι: 2. Die Querspindeln 7, 8 dieser Getriebe nehmen mit ihrem äußeren Vierkant die Handantriebskurbel auf. Die Querspindeln 7,8 mit ihren Kegelrädern können durch achsiale Verschiebung ihrer Lagerung 9, ίο beliebig außer Eingriff mit den Bohrspindeln gebracht werden. Die Lagerungen werden durch Rasten ii, 12 in ihren Stellungen gesichert. Bei Handbetrieb werden die Bürsten vom Kollektor abgehoben, der leer mitlaufende Motoranker wirkt als Schwungrad.mounted on the motor shaft and is driven by a spur gear ratio 3 ι: 3 of the countershaft 2, which is also used to accommodate tools Morse cone and thrust bearing is equipped. The transmission receives its drive through Spur gear ratio 4 from the MotorweUe. As Figs. 1 and 3 show, act on Main drilling spindle 1 and countershaft 2 each have a bevel gearbox f>, 6 with translation ι: 2. The transverse spindles 7, 8 of this gear take with their outer square the hand drive crank. The transverse spindles 7,8 with their bevel gears can by axial displacement of their storage 9, ίο arbitrarily out of engagement with the drilling spindles to be brought. The bearings are in their positions by notches ii, 12 secured. In manual mode, the brushes are lifted from the collector, the idle motor armature acts as a Flywheel.
