Abstract
Description
Die Erfindung bezeichnet eine kombinierte Handwerkzeugmaschine wie einen Kombihammer mit einem Modiwahldrehschalter, insbesondere zur Schaltung eines Drehgetriebes und eines Schlagwerks.The Invention refers to a combined hand tool such as a Combination hammer with a mode dial rotary switch, in particular for switching a rotary gear and a striking mechanism.
Üblicherweise weisen kombinierte Handwerkzeugmaschinen mehrere, wahlfrei in einen Kraftfluss vom antreibenden Motor zum angetriebenen Werkzeug integrierbare, Transformationsmodule auf, bspw. ein mehrstufiges Schaltgetriebe, ein Schlagwerk oder eine Gehäusearretierung. Bei zumindest zwei Transformationsmodulen ist zur Erzeugung zumindest dreier verschiedener Kombinationsmodi über einen gemeinsamen Modiwahldrehschalter eine Aufteilung dessen Drehbewegung in zwei unabhängige Teilbewegungen notwendig, die zur Steuerung je eines Transformationsmoduls dienen.Usually combined hand tool machines have several, optionally in a power flow integrable from the driving motor to the powered tool, Transformation modules on, for example, a multi-stage manual transmission, a striking mechanism or a housing lock. In at least two transformation modules is at least for generating Three different combination modes via a common mode dial rotary switch a division of its rotational movement in two independent part movements necessary, which serve to control each of a transformation module.

Die Aufgabe der Erfindung besteht in der Realisierung eines staubunempfindlicheren Modiwahldrehschalters einer kombinierten Handwerkzeugmaschine für zumindest drei Modi.The The object of the invention is to realize a dust-insensitive Modiwahldrehschalters a combined hand tool for at least three modes.
Die Aufgabe wird im Wesentlichen durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The The object is essentially achieved by the features of claim 1 solved. Advantageous developments emerge from the subclaims.
So weist eine kombinierte Handwerkzeugmaschine mehrere, zumindest teilweise in einen Kraftfluss vom antreibenden Motor zum angetriebenen Werkzeug integrierbare, Transformationsmodule auf, die zumindest teilweise über einen gemeinsamen, von aussen händisch um eine Schaltachse drehschwenkbaren Modiwahldrehschalter zuschaltbar sind, welcher formschlüssig steuernd mit einem translatorisch verschiebbaren Schaltblock eines ersten Transformationsmoduls verbunden ist, wobei dem Modiwahldrehschalter eine zur Schaltachse parallel angeordnete, zumindest in einem Schaltwinkelbereich drehschwenkbare Schaltnockenwelle eines zweiten Transformationsmoduls zugeordnet ist, welche mit dem Modiwahldrehschalter formschlüssig steuerbar verbunden ist.So has a combined hand tool several, at least partially in a power flow from the driving motor to the driven tool integrable, transformation modules that at least partially via a common, from the outside by hand switchable to a switching axis swiveling mode dial rotary switch are, which form fit Controlling with a translationally displaceable switching block first transformation module is connected to the mode dial rotary switch one to the shift axis arranged in parallel, at least in a switching angle range pivotable camshaft of a second transformation module is assigned, which can be positively controlled with the mode selector rotary switch connected is.
Indem dem Modiwahldrehschalter eine zur Schaltachse parallel angeordnete Schaltnockenwelle drehschwenkbar zugeordnet ist, ist diese selbst bei hoher Staubbelastung problemlos über die Gesamtlebensdauer der Handwerkzeugmaschine reibarm gelagert. Zudem lassen sich in einfacher Weise mit dem Modiwahldrehschalter wahlfrei zumindest drei Modi schalten.By doing the Modiwahldrehschalter a parallel to the switching axis arranged Switching camshaft is associated drehschwenkbar, this is itself with high dust load over the entire service life of the Hand tool machine mounted friction. In addition, it can be easier Mode with the mode selector dial optionally at least three modes turn.
Vorteilhaft ist die Schaltnockenwelle über eine ineinander greifende Zahnpaarung formschlüssig mit dem Modiwahldrehschalter verbunden, wodurch ein hohes Schaltdrehmoment übertragbar ist.Advantageous is the switching camshaft over a interlocking tooth pairing form-fitting with the mode selector rotary switch connected, whereby a high switching torque is transferable.
Vorteilhaft ist die Schaltnockenwelle senkrecht zur Werkzeugachse angeordnet, wodurch durch Verdrehung einer Schaltnocke eine erste Versetzung längs der Werkzeugachse bewirkt wird.Advantageous the switching camshaft is arranged perpendicular to the tool axis, whereby by rotation of a switching cam, a first displacement along the Tool axis is effected.
Vorteilhaft greift ein exzentrisch gelagerter Stift des Modiwahldrehschalters formschlüssig in einen senkrecht zur Schaltachse verlaufenden Mitnahmeschlitz eines Schaltbleches des Schaltblocks ein, wodurch die Drehschwenkbewegung des Schaltblocks eine zweite Versetzung längs der Werkzeugachse bewirkt.Advantageous engages an eccentrically mounted pin of the mode selector knob form-fitting in a direction perpendicular to the indexing axis driving slot a switching plate of the switching block, whereby the rotary pivoting movement the switching block causes a second displacement along the tool axis.
Vorteilhaft ist das erste Transformationsmodul als, weiter vorteilhaft zweistufiges, Schaltdrehgetriebe ausgeführt, welches durch den Schaltblock, der weiter vorteilhaft als Zahnradblock ausgebildet ist, umschaltbar ist, wodurch die Modi insbesondere mit einem ersten Gang oder einen zweiten Gang kombinierbar sind.Advantageous is the first transformation module as, more advantageously two-stage, Turnout gearbox designed, which by the switching block, which further advantageous than gear block is formed, is switchable, whereby the modes in particular with a first gear or a second gear can be combined.
Vorteilhaft ist das zweite Transformationsmodul als durch die Schaltnocke zuschaltbares Schlagwerk, weiter vorteilhaft als Ratschenschlagwerk mit zwei axial längs der Werkzeugachse ineinander eingreifbaren Rastscheiben ausgeführt, wodurch mit der Schaltnocke über eine von dieser gesteuert versetzbare Arbeitsspindel direkt eine Beabstandung der beiden Rastscheiben und somit eine Deaktivierung des Schlagwerks bewirkt wird.Advantageous is the second transformation module as switchable by the switching cam Schlagwerk, further advantageous as a ratchet impactor with two axial along the Tool axis interlocking locking discs running, which with the switch cam over a controlled by this displaceable work spindle directly a spacing the two locking discs and thus a deactivation of the percussion is effected.
Die Erfindung wird bezüglich eines vorteilhaften Ausführungsbeispiels näher erläutert mit:The invention is with respect to an advantage adhesion embodiment explained in more detail with:
