Description

Die Erfindung betrifft eine Hand-Werkzeugmaschine, insbesondere Dübelfräse, mit mindestens einem innerhalb eines Arbeitsbereichs vor eine Frontanschlagfläche der Hand-Werkzeugmaschine verstellbaren oder vorstehenden Zerspanungswerkzeug zum Bohren und/oder Fräsen einer Ausnehmung in eine Werkstück-Frontseite, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a hand-held machine tool, in particular dowel milling machine, with at least one cutting tool which is adjustable or projecting within a working area in front of a front stop surface of the hand-held machine tool for drilling and / or milling a recess in a workpiece front, according to the preamble of claim 1.

Eine derartige Hand-Werkzeugmaschine in Gestalt einer Dübelfräse wird von der Anmelderin gefertigt und ist in DE 10 2005 036 213 B3 beschrieben. Aus der Frontanschlagfläche sind zwei Queranschlag-Stäbe ausschiebbar, die aneinander entgegengesetzten Seiten des Arbeitsbereichs des Zerspanungswerkzeugs angeordnet sind. Das Zerspanungswerkzeug ist ein Fräskopf, der innerhalb des Arbeitsbereiches schwenkbeweglich ist und somit ein Langloch bzw. eine Längsausnehmung fräst. In diese Längsausnehmung kann ein Dübel eingesetzt werden.Such a hand-held machine tool in the form of a dowel cutter is manufactured by the applicant and is in DE 10 2005 036 213 B3 described. From the front abutment surface two transverse stop rods are pushed out, which are arranged on mutually opposite sides of the working area of the cutting tool. The cutting tool is a milling head, which is pivotable within the working area and thus mills a slot or a longitudinal recess. In this longitudinal recess, a dowel can be used.

Die seitherigen Queranschlageinrichtungen sind in Längsbohrungen geführt, was bei Verschmutzung zu einem Verklemmen führen kann. Die Bohrungen, in denen die Rundstift-Queranschlageinrichtungen längsverstellbar sind, können nur verhältnismäßig schwer gereinigt werden.The lateral cross-abutment devices are guided in longitudinal bores, which can lead to jamming in case of contamination. The holes in which the round pin Queranschlageinrichtungen are longitudinally adjustable, can only be cleaned relatively difficult.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine verbesserte Queranschlageinrichtung bei einer Hand-Werkzeugmaschine der eingangs genannten Art bereitzustellen.It is therefore the object of the present invention to provide an improved cross-stop device in a Hand tool machine of the type mentioned above.

Zur Lösung dieser Aufgabe ist eine Hand-Werkzeugmaschine mit den Merkmalen des Anspruchs 1 vorgesehen.To solve this problem, a hand-held power tool with the features of claim 1 is provided.

Die schwenkbewegliche Queranschlageinrichtung neigt weniger zur Verschmutzung als die längsbewegliche Queranschlageinrichtung des Standes der Technik. Vorteilhaft ist ein Schwenkspiel, das ein Reinigen der Queranschlageinrichtung bzw. eines Schwenklagers der Queranschlageinrichtung leicht macht.The pivotal cross-bumper tends less to fouling than the prior art longitudinally-movable cross-bumper. Advantageously, a pivoting play, which makes cleaning the Queranschlageinrichtung or a pivot bearing of Queranschlageinrichtung easy.

Die Queranschlageinrichtung ist beispielsweise in der Art einer Queranschlagklinke ausgestaltet, die aus der Frontanschlagfläche ausschwenken kann. In der Ruhestellung fluchtet die Queranschlageinrichtung mit der Frontanschlagfläche oder ist hinter dieser angeordnet, so dass sie unwirksam ist.The Queranschlageinrichtung is configured for example in the manner of a transverse stop pawl, which can swing out of the front stop surface. In the rest position the Queranschlageinrichtung flush with the front stop surface or is arranged behind this, so that it is ineffective.

Die Hand-Werkzeugmaschine hat mindestens zwei an einander entgegengesetzten Seiten des mindestens einen Zerspanungswerkzeugs beweglich gelagerte Queranschlageinrichtungen. Diese Queranschlageinrichtungen können zur Definition unterschiedlicher oder vorteilhaft gleicher Querabstände relativ zu dem Arbeitsbereich beabstandet sein. Die Queranschlageinrichtungen können an einander entgegengesetzte Querseiten des Werkstücks angelegt werden, so dass bezüglich dieser Werkstück-Querseiten jeweils Ausnehmungen mit denselben oder unterschiedlichen Querabständen fräs- oder bohrbar sind.The hand-held power tool has at least two opposing sides of the at least one cutting tool movably mounted Queranschlageinrichtungen. This Queranschlageinrichtungen may be spaced relative to the work area for defining different or advantageously equal transverse distances. The Queranschlageinrichtungen can be applied to opposite transverse sides of the workpiece, so that with respect to these workpiece transverse sides each recesses with the same or different transverse distances can be milled or drilled.

Die Queranschlageinrichtung weist als Queranschlag zweckmäßigerweise mindestens eine Queranschlagplanfläche auf. Die Planfläche erlaubt ein flächiges Anlegen an das Werkstück, was eine hohe Maßgenauigkeit ermöglicht. Zudem ist die Gefahr verringert, dass die Queranschlagfläche in eine Ausnehmung des Werkstückes gelangt, so dass der Querabstand zwischen der gebohrten oder gefrästen Ausnehmung im Werkstück und der Werkstück-Querseite exakt eingehalten wird.The Queranschlageinrichtung has as a transverse stop expediently at least one transverse stop plan surface. The flat surface allows a flat application to the workpiece, which allows a high dimensional accuracy. In addition, the risk is reduced that the transverse stop surface in a recess of the Workpiece passes, so that the transverse distance between the drilled or milled recess in the workpiece and the workpiece transverse side is maintained exactly.

Zweckmäßigerweise ist die mindestens eine Queranschlageinrichtung in die Anschlagstellung federbelastet. Die Queranschlageinrichtung schwenkt dann selbsttätig in die Anschlagstellung.Conveniently, the at least one transverse stop device is spring-loaded in the stop position. The Queranschlageinrichtung then pivots automatically in the stop position.

Dies ermöglicht, dass die Queranschlageinrichtung leicht austauschbar ist, beispielsweise zur Anpassung an Maßtoleranzen und/oder wenn andere Querabstände gewünscht sind.The at least one transverse stop device is advantageously detachably fastened to the hand-held machine tool. This allows the cross-abutment device to be easily exchanged, for example, to adapt to dimensional tolerances and / or if other transverse distances are desired.

Vorteilhaft hat die Hand-Werkzeugmaschine eine Feststelleinrichtung zum Festlegen der mindestens einen Queranschlageinrichtung in einer Schwenkstellung, beispielsweise der Ruhestellung und/oder der Anschlagstellung. Auch eine Schwenkstellung dazwischen kann vorteilhaft mit der Feststelleinrichtung festgelegt werden.Advantageously, the hand machine tool has a locking device for fixing the at least one transverse stop device in a pivoting position, for example, the rest position and / or the stop position. Also, a pivot position between can be advantageously determined with the locking device.

Die Feststelleinrichtung umfasst beispielsweise eine Schraube oder Klemme, die zwischen einer Freigabestellung, in der die Queranschlageinrichtung schwenken kann, und einer die Queranschlageinrichtung schwenkfest haltenden Haltestellung verstellbar ist. Die Schraube oder Klemme kann an der Queranschlageinrichtung oder auch am Gehäuse, einem Schlitten oder einem sonstigen Bauteil der Hand-Werkzeugmaschine beweglich gelagert oder schraubbar sein.The locking device comprises, for example, a screw or clamp that can be adjusted between a release position in which the cross-abutment device can pivot and a holding position that holds the cross-abutment device so that it can pivot. The screw or clamp can be movably mounted or screwed to the cross-abutment device or on the housing, a carriage or other component of the hand-held machine tool.

Die Queranschlageinrichtung ist zweckmäßigerweise in einer Schwenkaufnahme angeordnet. Die Schwenkaufnahme ist vorzugsweise als eine Art Taschenausnehmung ausgestaltet. Eine Verliersicherung sichert die Queranschlageinrichtung in der Schwenkaufnahme, so dass diese nicht verloren gehen kann. Die Queranschlageinrichtung schwenkt aus der Schwenkaufnahme vor die Frontanschlagfläche der Hand-Werkzeugmaschine vor. In der Ruhestellung ist die Queranschlageinrichtung vorteilhaft vollständig in die Schwenkaufnahme eingeschwenkt.The Queranschlageinrichtung is advantageously arranged in a swivel mount. The pivot receptacle is preferably designed as a kind of pocket recess. A captive secures the Queranschlageinrichtung in the swivel mount so that it can not be lost. The Queranschlageinrichtung pivots from the swivel mount in front of the front stop surface of the hand-held machine tool. In the rest position, the transverse stop device is advantageously completely pivoted into the pivot receptacle.

Die Verliersicherung umfasst beispielsweise eine an der Hand-Werkzeugmaschine beweglich angeordnetes, in Richtung der Queranschlagseinrichtung verstellbares Sicherungsglied, z.B. eine Klinke, Schraube, Klemme oder dergleichen.The captive comprises, for example, an on the hand-machine tool movably arranged, in the direction of the transverse stop means adjustable locking member, e.g. a latch, screw, clamp or the like.

Beispielsweise steht das Sicherungsglied in der ersten und der zweiten Längsstellung vor einander entgegengesetzte Seiten der Queranschlageinrichtung vor. In der zweiten, die Queranschlageinrichtung schwenkfest festlegenden Längsstellung greift das Sicherungsglied beispielsweise in einer ortsfeste Ausnehmung an der Hand-Werkzeugmaschine ein. In der ersten, als Verliersicherungs-Längsstellung ausgestalteten Längsstellung schlägt das Sicherungsglied beispielsweise an einen Anschlag an, so dass ein vollständiges Ausschwenken der Queranschlageinrichtung aus der Schwenkaufnahme verhindert ist.The securing member secures the Queranschlageinrichtung expediently in a first longitudinal position against losing and sets it in a second longitudinal position in a pivotal position fixed pivotally. For example, in the first and second longitudinal positions, the securing member protrudes from opposite sides of the transverse abutment device. In the second, the Queranschlageinrichtung pivotally fixing longitudinal position, the securing member engages, for example, in a stationary recess on the hand-held machine tool. In the first, designed as Verliersicherungs longitudinal position longitudinal position, the securing member strikes, for example, to a stop, so that a complete pivoting of the Queranschlageinrichtung is prevented from the pivot receiving.

Die Queranschlageinrichtung ist zweckmäßigerweise durch ein Schwenkteil oder einen Schwenkkörper gebildet. Das Schwenkteil hat beispielsweise eine armartige oder klinkenartige Gestalt.The Queranschlageinrichtung is advantageously formed by a pivoting part or a swivel body. The pivoting part has, for example, a arm-like or latch-like shape.

Die Schwenkachse der Queranschlageinrichtung verläuft zweckmäßigerweise neben einer Mittelachse des Zerspanungswerkzeugs. Die Mittelachse des Zerspanungswerkzeugs ist zugleich eine Mittelachse des Arbeitsbereiches des Zerspanungswerkzeugs und somit eine Mittelachse der in das Werkstück gebohrten oder gefrästen Ausnehmung. Die Schwenkachse verläuft neben diesen Mittelachsen, so dass sich die Queranschlageinrichtung nicht in bereits gebohrten oder gefrästen Löchern bzw. Ausnehmungen, so dass ein flüssiges Arbeiten mit der erfindungsgemäßen Hand-Werkzeugmaschine möglich ist.The pivot axis of the Queranschlageinrichtung expediently runs next to a central axis of the cutting tool. The central axis of the cutting tool is at the same time a central axis of the working region of the cutting tool and thus a central axis of the bore bored or milled into the workpiece. The pivot axis runs next to these central axes, so that the cross-abutment device is not in already drilled or milled holes or recesses, so that a liquid work with the hand-held machine tool according to the invention is possible.

Vorteilhaft hat die Hand-Werkzeugmaschine mehrere Queranschlageinrichtungen. Die Queranschlageinrichtungen können verschiedene Querabstände zwischen dem Arbeitsbereich des mindestens einen Zerspanungswerkzeugs und der Werkstück-Querseite definieren. Somit könnte man auch von einer Queranschlageinrichtungsanordnung sprechen.Advantageously, the hand-held machine tool has several cross-stop devices. The transverse stop devices may define different transverse distances between the working region of the at least one cutting tool and the workpiece transverse side. Thus, one could also speak of a Queranschlageinrichtungsanordnung.

Weiterhin ist es zweckmäßig, wenn die erfindungsgemäße Hand-Werkzeugmaschine weitere Anschlageinrichtungen hat, z.B. eine Winkelanschlageinrichtung mit mindestens einer Winkelanschlagfläche, die quer zu dem Queranschlag und der Frontanschlagfläche winkelig ist. Somit kann beispielsweise der Abstand der Ausnehmung oder Bohrung im Werkstück sowohl zur Werkstück-Querseite als auch zu einer zu dieser sowie zu der Werkstück-Frontseite winkeligen Werkstückfläche, beispielsweise einer Werkstück-Oberseite oder -Unterseite, exakt eingehalten werden.Furthermore, it is expedient if the hand-held power tool according to the invention has further stop devices, for example an angle stop device with at least one angled stop surface, which is angled transversely to the transverse stop and the front stop face. Thus, for example, the distance of the recess or bore in the workpiece both to the workpiece lateral side and to an angle to this and the workpiece front side workpiece surface, for example a workpiece top or bottom, are maintained exactly.

Vorteilhaft ist Winkelanschlageinrichtung zur Festlegung eines Winkels zwischen der Winkelanschlagfläche und der Frontanschlagfläche schwenkbeweglich gelagert.Winkelanschlageinrichtung is advantageous for fixing an angle between the angle stop surface and the front stop surface pivotally mounted.

Die Hand-Werkzeugmaschine ist beispielsweise eine Dübelfräse. Das Zerspanungswerkzeug kann beispielsweise ein Fräskopf sein, der innerhalb des Arbeitsbereiches schwenkbeweglich ist, um die Ausnehmung als eine Längsausnehmung zu Fräsen. Es versteht sich, dass das mindestens eine Zerspanungswerkzeug auch einen oder mehrere Bohrer umfassen kann. Somit ist die Erfindung auch bei Einspindelbohrmaschinen oder Mehrspindelbohrmaschinen einsetzbar. Auch eine kombinierte Bohr- und Fräsmaschine kann mit der oder den erfindungsgemäßen Queranschlageinrichtungen ausgestattet sein.The hand-held machine tool is, for example, a dowel cutter. For example, the cutting tool may be a milling head that is pivotable within the working area to mill the recess as a longitudinal recess. It is understood that the at least one cutting tool can also comprise one or more drills. Thus, the invention can also be used in single-spindle drilling machines or multi-spindle drilling machines. A combined drilling and milling machine can also be equipped with the cross-abutment device (s) according to the invention.

Eine Dübelfräse 11, die man auch als Dübellochfräse bezeichnen könnte, bildet eine erfindungsgemäße Hand-Werkzeugmaschine 10. Ein Elektromotor 12, der beispielsweise über ein nicht dargestelltes elektrisches Versorgungskabel oder durch ein an Bord der Hand-Werkzeugmaschine 10 befindliches Akkumulatorbauteil mit elektrischer Energie versorgt wird, treibt direkt über ein nicht dargestelltes Getriebe ein Zerspanungswerkzeug 13 an. Das Zerspanungswerkzeug 13 ist ein Fräswerkzeug oder Fräser 14 zum Fräsen von Dübellöchern in ein schematisch und nur teilweise dargestelltes Werkstück 24.A dowel cutter 11, which could also be referred to as a dowel cutter, forms a hand-held power tool 10 according to the invention. An electric motor 12 which is supplied with electrical energy, for example via an electrical supply cable, not shown, or by an accumulator component located on board the hand-held power tool 10, drives a cutting tool 13 directly via an unillustrated gearbox. The cutting tool 13 is a milling tool or cutter 14 for milling dowel holes in a schematically and only partially illustrated workpiece 24th

An einem den Motor 12 enthaltenden Gehäuse 16, vor das der Fräser 14 vorsteht, ist ein Anschlagschlitten 15 mittels schematisch dargestellter Linearführungen 17 linear beweglich angeordnet. Das Gehäuse 16 kann an einem hinteren Bereich 28 sowie an einem seitlich, in der Zeichnung nach oben, vor den Anschlagschlitten 15 vorstehenden Handgriff 18, der zweckmäßigerweise knebelartig ist, ergriffen werden, um das Gehäuse 16 mit dem nach vorn vorstehenden Fräser 14 zu dem Anschlagschlitten 15 hin zu verschieben, wobei der Fräser 14 durch eine Längsgestalt aufweisende Ausnehmung 19 an einer Frontanschlagfläche 20 einer Frontanschlageinrichtung 21 nach vorn austritt und vor eine die Frontanschlagfläche 20 bereitstellende Frontwand 22 vorsteht, was in Figur 1 dargestellt ist.On a housing 12 containing the motor 12, in front of which the cutter 14 protrudes, a stop carriage 15 is arranged to be linearly movable by means of schematically illustrated linear guides 17. The housing 16 may be at a rear portion 28 and at a laterally, in the drawing up, in front of the stop slide 15 projecting handle 18, which is conveniently like a gag, be taken to the housing 16 with the forwardly projecting cutter 14 to the stop carriage 15 to move, the cutter 14 by a longitudinal shape having recess 19 on a front stop surface 20 a Frontanschlageinrichtung 21 leaking forward and in front of a front stop surface 20 providing front wall 22 protrudes, which in FIG. 1 is shown.

Mittels einer Tiefeneinstelleinrichtung 30 kann eine Frästiefe 29, das heißt das Maß, mit dem der Fräser 14 vor die Frontanschlagfläche 20 vorsteht, eingestellt werden. Der die Frästiefe 29 anzeigende Doppelpfeil verdeutlicht zugleich die Verstellbewegung von Anschlagschlitten 15 und Gehäuse 16 relativ zueinander.By means of a Tiefeneinstelleinrichtung 30, a milling depth 29, that is, the degree with which the cutter 14 projects in front of the front stop surface 20, can be adjusted. At the same time, the double arrow indicating the depth of cut 29 clarifies the adjustment movement of stop carriages 15 and housing 16 relative to each other.

Mit dem vor die Frontwand 22 vorstehenden Fräser 14 ist eine Ausnehmung 31 in einer Werkstück-Frontseite 23 eines Werkstücks 24 fräsbar. Die Ausnehmung 31 ist eine Längsausnehmung 32, die beispielsweise zum Einsetzen eines Dübels, eines Beschlagteils oder dergleichen geeignet ist. Die Längsgestalt der Ausnehmung 19 an der Frontanschlagfläche 20 ermöglicht ein Hin- und Herschwenken des Fräsers 14, der innerhalb eines Schwenkbereichs 33 schwenkbeweglich ist. Somit ist es möglich, mit dem Fräser 14 die ebenfalls eine Längsgestalt aufweisende Längsausnehmung 32, sozusagen ein Langloch, zu fräsen.With the front of the front wall 22 projecting cutter 14, a recess 31 in a workpiece front side 23 of a workpiece 24 can be milled. The recess 31 is a longitudinal recess 32, which is suitable for example for inserting a dowel, a fitting or the like. The longitudinal shape of the recess 19 on the front stop surface 20 allows a back and forth pivoting of the cutter 14, which is pivotable within a pivoting range 33. Thus, it is possible with the cutter 14, which also has a longitudinal shape having longitudinal recess 32, so to speak a slot to mill.

Der Schwenkbereich 33 definiert gleichzeitig eine Querlänge 34 eines Arbeitsbereichs 35 des Zerspanungswerkzeugs 13 oder Fräsers 14 bzw. eine entsprechende Querlänge der gefrästen Längsausnehmung 32. Ein Durchmesser des Fräsers 14 bestimmt eine Querbreite 36 des Arbeitsbereichs 35 und somit auch die entsprechende Querbreite der in das Werkstück 24 gefrästen Längsausnehmung 32.The pivoting region 33 simultaneously defines a transverse length 34 of a working region 35 of the cutting tool 13 or milling cutter 14 or a corresponding transverse length of the milled longitudinal recess 32. A diameter of the milling cutter 14 determines a transverse width 36 of the working region 35 and thus also the corresponding transverse width of the workpiece 24 Milled longitudinal recess 32nd

Zur Positionierung der Hand-Werkzeugmaschine 10 relativ zum Werkstück 24 und somit zur örtlichen Festlegung der Längsausnehmung 32 sind weitere Anschläge an dem Anschlagschlitten 15 vorgesehen. So kann der Anschlagschlitten 15 beispielsweise mit einer Bodenfläche 37 auf eine Grundfläche, die beispielsweise das Werkstück 24 oder eine Werkbank oder dergleichen bereitstellt, aufgesetzt werden. Die Bodenfläche 37 bildet einen Basisanschlag 38, der zu der Frontanschlagfläche 20 winkelig, zweckmäßigerweise rechtwinkelig ist.For positioning of the hand-held machine tool 10 relative to the workpiece 24 and thus for the local definition of the longitudinal recess 32 are further stops on the stop carriage 15th intended. Thus, the stop carriage 15, for example, with a bottom surface 37 on a base, which provides, for example, the workpiece 24 or a workbench or the like, are placed. The bottom surface 37 forms a base stop 38, which is angled to the front stop surface 20, suitably rectangular.

Ferner ist an dem Anschlagschlitten 15 eine Winkelanschlageinrichtung 39 mit einer an einer Winkelanlageplatte 41 vorgesehenen Winkelanschlagfläche 40 angeordnet. Die Winkelanlageplatte 41 ist an Schwenklagern 42 schwenkbeweglich bezüglich einer die Bodenfläche 37 bereitstellenden Bodenplatte 43 des Anschlagschlittens 15 gelagert. Die Winkelanlageplatte 41 kann zwischen der in der Zeichnung gezeigten Grundstellung, bei der die Winkelanschlagfläche 40 mit der Frontanschlagfläche 20 fluchtet, und einer in der Zeichnung nach unten geschwenkten, zur Frontanschlagfläche 20 winkeligen Stellung geschwenkt werden. In der am weitesten nach unten geschwenkten Schwenkstellung sind die Winkelanschlagfläche 40 und die Bodenfläche 37 zueinander parallel. Zum Festlegen der jeweiligen Schwenkstellung der Winkelanlageplatte 41 dient eine Schwenkeinstelleinrichtung 44, deren jeweilige Winkelposition festlegbar ist, beispielsweise mit einem Klemmhebel 45. Die vom Gehäuse 16 weggeschwenkte Winkelanlageplatte 41 kann beispielsweise auf eine Werkstück-Oberseite 46 des Werkstücks 24 aufgelegt werden, um einen Abstand zwischen der Werkstück-Oberseite 46 und der Längsausnehmung 32 zu definieren.Furthermore, an angle stop 39 is arranged on the stop carriage 15 with an angle stop plate 41 provided on an angle stop surface 40. The angle contact plate 41 is pivotally mounted on pivot bearings 42 with respect to a bottom surface 37 providing the bottom plate 43 of the stop carriage 15. The angle contact plate 41 can be pivoted between the basic position shown in the drawing, in which the angle stop surface 40 is aligned with the front stop surface 20, and a pivoted in the drawing down, the front stop surface 20 angular position. In the pivoting position pivoted furthest downwards, the angle stop surface 40 and the bottom surface 37 are parallel to each other. To set the respective pivot position of the angle contact plate 41 is a pivot adjustment 44 whose respective angular position can be fixed, for example with a clamping lever 45. The pivoted away from the housing 16 angle contact plate 41 can be placed for example on a workpiece top 46 of the workpiece 24 by a distance between the workpiece top 46 and the longitudinal recess 32 to define.

Queranschlageinrichtung 25a, 25b am Anschlagschlitten 15 stellen Queranschläge 26 zum Anlegen an Werkstück-Querseiten 27 bereit, wobei in der Zeichnung nur eine Werkstück-Querseite 27 dargestellt ist. Die beiden Queranschlageinrichtungen 25a, 25b sind an Schwenklagern 47 an dem Anschlagschlitten 15 schwenkbeweglich gelagert, so dass sie zwischen einer in Figur 1 gezeigten Anschlagstellung A, bei der sie vor die Frontanschlagfläche 20 vorstehen, und einer in Figur 2 gezeigten Ruhestellung R schwenkbeweglich sind, bei der sie zumindest mit der Frontanschlagfläche 20 fluchten oder hinter diese zurücktreten. Dann ist das Werkstück 24 seitlich etwa entsprechend dem den Schwenkbereich 33 anzeigenden Doppelpfeil an der Frontanschlagfläche 20 frei verschieblich, das heißt die in die Ruhestellung R geschwenkte Queranschlageinrichtung 25a, 25b wirkt nicht als Queranschlag und ist insofern inaktiv. In der vor die Frontanschlagfläche 20 aufgeschwenkten Anschlagstellung A hingegen definiert die jeweilige Queranschlageinrichtung 25a, 25b einen Querabstand 48 zwischen der Werkstück-Querseite 27 und der in das Werkstück 24 zu fräsenden Ausnehmung 31. Der Queranschlag 26 ist im Querabstand 48 zu dem Arbeitsbereich 35 beabstandet.Queranschlageinrichtung 25a, 25b on stop carriage 15 provide transverse stops 26 for applying to workpiece transverse sides 27 ready, wherein in the drawing, only a workpiece transverse side 27 is shown. The two Queranschlageinrichtungen 25 a, 25 b are pivotally mounted on pivot bearings 47 on the stop carriage 15, so that they between one in FIG. 1 shown stop position A, in which they protrude in front of the front stop surface 20, and a in FIG. 2 shown rest position R are pivotable, in which they are at least flush with the front stop surface 20 or withdraw behind this. Then, the workpiece 24 is laterally displaced about corresponding to the pivoting area 33 indicating double arrow on the front stop surface 20, that is, the pivoted into the rest position R Queranschlageinrichtung 25a, 25b does not act as a transverse stop and is therefore inactive. In contrast, in the stop position A pivoted up in front of the front abutment surface 20, the respective transverse abutment device 25a, 25b defines a transverse distance 48 between the workpiece transverse side 27 and the recess 31 to be milled into the workpiece 24. The transverse abutment 26 is spaced at a transverse distance 48 from the working region 35.

An dem Zerspanungswerkzeug 13 zugewandten Innenseiten von Schwenkteilen 50 der Queranschlageinrichtung 25a, 25b sind Queranschlagplanflächen 51 vorgesehen, die an die jeweilige Werkstück-Querseite 27 anlegbar sind. Wenn die Werkstück-Querseite 27 beispielsweise Riffelungen, Bohrungen oder sonstige Vertiefungen aufweist, wird dies durch die verhältnismäßig großflächigen Queranschlagplanflächen 51 sozusagen kompensiert, da der Queranschlag 26 dann nicht in die jeweilige vertiefung eindringt, so dass der Querabstand 48 auf das exakte, gewünschte Maß festgelegt ist.On the cutting tool 13 facing inner sides of pivoting parts 50 of the Queranschlageinrichtung 25a, 25b Queranschlagplanflächen 51 are provided which can be applied to the respective workpiece transverse side 27. If the workpiece transverse side 27 has, for example, corrugations, bores or other indentations, this is compensated by the relatively large cross-abutment plane surfaces 51, so to speak, since the transverse stop 26 then does not penetrate into the respective recess, so that the transverse spacing 48 is set to the exact, desired dimension is.

Die beiden Schwenkteile 50 haben einen Lagerabschnitt 52 sowie einen zu diesem winkeligen Anschlagarm 53, an dessen dem Zerspanungswerkzeug 13 zugewandter Innenseite die Queranschlagplanfläche 51 vorgesehen ist. Somit haben die Schwenkteile 50 eine klinkenartige Gestalt. Die Anschlagarme 53 sind in Schwenkaufnahmen 54 an der von der Bodenplatte 43 abstehenden Frontwand 22 eines Basisteils 55 des Anschlagschlittens 15 in ihrer Ruhestellung R angeordnet. In der Anschlagstellung A schwenken die Anschlagarme 53 im Wesentlichen vollständig aus den Schwenkaufnahmen 54 aus, wobei jedoch ein Mittelabschnitt 56 zwischen dem Anschlagarm 53 und dem Lagerabschnitt 52 auch in der Anschlagstellung A teilweise zwischen einer dem Fräser 14 näheren und der Seitenwand 57 und einer von dem Zerspanungswerkzeug 13 entfernteren äußeren Seitenwand 58 der Schwenkaufnahme 54 verbleibt. Diese Maßnahme sorgt in Zusammenwirkung mit den nachfolgend beschriebenen Maßnahmen dafür, dass die Schwenkteile 50 unverlierbar am Anschlagschlitten 15 gehalten werden.The two pivoting parts 50 have a bearing section 52 as well as an angled stop arm 53, at the inner side of which the cutting tool 13 faces, the transverse stop plan face 51 is provided. Thus, the pivot parts 50 have a pawl-like shape. The stop arms 53 are in swivel mounts 54 on the protruding from the bottom plate 43 front wall 22 of a base part 55 of the stop carriage 15 arranged in their rest position R. In the stop position A, the stop arms 53 substantially completely pivot out of the pivot receivers 54, but a central portion 56 between the stop arm 53 and the bearing portion 52 partially in the stop position A between a nearer the cutter 14 and the side wall 57 and one of the Cutting tool 13 more distant outer side wall 58 of the pivot receiver 54 remains. This measure, in cooperation with the measures described below, ensures that the pivoting parts 50 are held captive on the stop carriage 15.

Die Schwenklager 47 befinden sich außerhalb der Schwenkaufnahmen 54. An einem von den Schwenkaufnahmen 54 entfernten äußeren Randbereich, etwa einem Eckbereich, durchdringen Schwenkbolzen 60 die Schwenkteile 50 und stehen vor diese vor, so dass Lagervorsprünge 59 an den Queranschlageinrichtungen 25a, 25b gebildet sind. Die Lagervorsprünge 59 sind in Lagerausnehmungen 61 an den innere Seitenwänden 57 schwenkbar aufgenommen.The pivot bearings 47 are located outside the pivot receptacles 54. On one of the pivot receivers 54 remote outer edge region, such as a corner region, pivot pins 60 penetrate the pivot members 50 and projecting in front of them, so that bearing projections 59 are formed on the Queranschlageinrichtungen 25 a, 25 b. The bearing projections 59 are pivotally received in bearing recesses 61 on the inner side walls 57.

Verliersicherungen 62 sichern die Schwenkteile 50 in den Schwenkaufnahmen 54 und begrenzen zudem ein Ausschwenken der Schwenkteile 50 über die Anschlagstellung A (in Figur 1 gezeigt) hinaus. Die Verliersicherungen 62 umfassen ein Sicherungsglied 63, beim Ausführungsbeispiel eine Schraube 64, insbesondere eine Wurmschraube, das eine Bohrung 65 am Lagerabschnitt 52 der Schwenkteile 50 durchdringt.Verliersicherungen 62 secure the pivoting parts 50 in the pivot receivers 54 and also limit pivoting of the pivoting parts 50 on the stop position A (in FIG. 1 shown). The Verliersicherungen 62 include a securing member 63, in the embodiment a screw 64, in particular a worm screw, which penetrates a bore 65 on the bearing portion 52 of the pivoting parts 50.

Das Sicherungsglied 63 sichert das jeweilige Schwenkteil 50 in einer in Figur 1 sichtbaren ersten Längsstellung 66 gegen ein Verlieren. In der Längsstellung 66 stehen der Lagervorsprung 59 und das Sicherungsglied 63 vor einander entgegengesetzte Seiten des Schwenkteils 50 vor, wobei das Sicherungsglied 63 in der Anschlagstellung A gegen einen Schwenkanschlag 68 anschlägt. Der Schwenkanschlag 68 wird beispielsweise durch die Oberseite der äußeren Seitenwand 58 gebildet.The securing member 63 secures the respective pivoting part 50 in an in FIG. 1 visible first longitudinal position 66 against losing. In the longitudinal position 66, the bearing projection 59 and the securing member 63 project from opposite sides of the pivoting part 50, wherein the securing member 63 abuts in the stop position A against a pivot stop 68. The pivot stop 68 is formed, for example, by the top of the outer side wall 58.

In einer zweiten Längsstellung 67 hingegen steht das Sicherungsglied 63 vor dieselbe Seite wie der Lagervorsprung 59 vor. In der in Figur 2 dargestellten Ruhestellung kann das Sicherungsglied 63 dann in eine Schwenkausnehmung 69 an der inneren Seitenwand 57 eindringen, wodurch das Schwenkteil 50 schwenkfest in der Ruhestellung R festgelegt ist. Somit wirkt die Verliersicherung 62 gleichzeitig als Feststelleinrichtung 70 zum schwenkfesten Festlegen der Schwenkteile 50 in einer Schwenkstellung, hier der Ruhestellung R. Es versteht sich, dass zum schwenkfesten Festlegen der Queranschlageinrichtungen 25a, 25b in einer anderen Schwenkstellung, z.B. der Anschlagstellung A, auch eine beim Ausführungsbeispiel nicht dargestellte weitere Schwenkausnehmung an der inneren Seitenwand 57 vorgesehen sein kann.In contrast, in a second longitudinal position 67, the securing member 63 projects in front of the same side as the bearing projection 59. In the in FIG. 2 shown rest position, the securing member 63 can then penetrate into a pivot recess 69 on the inner side wall 57, whereby the pivot member 50 is pivotally fixed in the rest position R. Thus, the captive 62 simultaneously acts as a locking device 70 for pivotally fixing the pivot parts 50 in a pivotal position, here the rest position R. It is understood that for pivotally fixing the Queranschlageinrichtungen 25 a, 25 b in another pivotal position, eg the stop position A, and a Embodiment not shown further pivot recess may be provided on the inner side wall 57.

Die beiden Schwenkteile 50 werden durch Federn 71 in die Anschlagstellung A belastet. An den in der Zeichnung nicht sichtbaren Stirnseiten der Lagerabschnitte 52 sind zweckmäßigerweise Vorsprünge vorgesehen, die in die Federn 71 eingreifen, so dass diese quer zu ihrer Spannrichtung geführt sind.The two pivoting parts 50 are loaded by springs 71 in the stop position A. At the non-visible in the drawing end faces of the bearing portions 52 projections are advantageously provided which engage in the springs 71 so that they are guided transversely to its clamping direction.

Ein Auswechseln der Schwenkteile 50 gestaltet sich ausgesprochen einfach. Der Bediener schraubt die Sicherungsglieder 63 aus den Bohrungen 65 heraus, so dass die Schwenkteile 50 aus den Schwenkaufnahmen 54 ausgeschwenkt und von der Hand-Werkzeugmaschine 10 entfernt werden können. An den entfernten Schwenkteilen 50 können auf einfache Weise Maßkorrekturen vorgenommen werden, beispielsweise durch Abschleifen der Queranschlagplanflächen 51. Ferner können die Schwenkteile 50 an sich gegen beispielsweise schmalere oder breitere Schwenkteile ausgetauscht werden, wenn den Querabstand 48 nicht einem gewünschten Maß entspricht.Replacing the pivoting parts 50 is very simple. The operator unscrews the securing members 63 out of the bores 65, so that the pivoting parts 50 can be swung out of the pivoting receivers 54 and removed from the hand-held power tool 10. Dimensional corrections can be made in a simple manner to the removed pivoting parts 50, for example by grinding the transverse stopper facing surfaces 51. Furthermore, the pivoting parts 50 can themselves be used against, for example, narrower or wider pivoting parts be replaced when the transverse distance 48 does not correspond to a desired level.

Untere, der Bodenfläche 37 nähere Abschnitte der Schwenkaufnahmen 54 haben eine verhältnismäßig große Weite, so dass zwischen den Schwenkteilen 50 und den entsprechenden Seiten- und Bodenwandungen der Schwenkaufnahme 54 ein großer Abstand vorhanden ist. Somit ist die Neigung der Schwenkteile 50 durch eindringenden Schmutz zu verklemmen verhältnismäßig gering. Zudem wird eventuell in die Schwenkaufnahmen 54 gelangter Schmutz beim Ausschwenken der Schwenkteile 50 in die Anschlagstellung A quasi selbsttätig aus den Schwenkaufnahmen 54 herausgefördert. Sollten diese dennoch einmal verschmutzt sein, können die Schwenkteile 50 leicht demontiert und die Schwenkaufnahmen 54 gereinigt werden.Lower, the bottom surface 37 closer portions of the pivot receivers 54 have a relatively large width, so that between the pivot members 50 and the corresponding side and bottom walls of the pivot receiver 54 a large distance is present. Thus, the tendency of the pivoting parts 50 to be clamped by penetrating dirt is relatively low. In addition, any dirt that may have entered the pivot receptacles 54 when the pivoting parts 50 are pivoted into the stop position A is virtually automatically conveyed out of the pivot receptacles 54. Should these nevertheless be dirty once, the pivoting parts 50 can be easily dismantled and the pivoting receptacles 54 cleaned.

Die Handhabung der Hand-Werkzeugmaschine 10 wird auch dadurch vereinfacht, dass eine Schwenkachse 72 der beiden Queranschlageinrichtungen 25a, 25b neben einer Mittelachse 73 des Zerspanungswerkzeugs 13 verläuft. Die Schwenkteile 50 verfangen sich dadurch nicht in bereits gefrästen, beispielsweise seitlich neben der Längsausnehmung 32 befindlichen Längsausnehmungen, wenn die Frontanschlagfläche 20 an die Werkstück-Frontseite 23 angelegt wird.The handling of the hand-held machine tool 10 is also simplified in that a pivot axis 72 of the two transverse stop devices 25a, 25b extends alongside a central axis 73 of the cutting tool 13. As a result, the pivoting parts 50 are not caught in already milled longitudinal recesses, for example located laterally next to the longitudinal recess 32, when the front abutment surface 20 is applied to the workpiece front side 23.

An einer dem Werkstück 24 zugewandten Vorderseite des Anschlagarms 53 sind zwei zueinander winkelige Schrägflächen 74, 75 angeordnet, die ein Einschwenken des Schwenkteils 50 in Richtung der Ruhestellung R begünstigen. Zwischen den beiden Schrägflächen 74, 75 ist der Anschlagarm 53 vorzugsweise gerundet. Wenn die klinkenartigen Schwenkteile 50 in die Anschlagstellung A geschwenkt sind, steht sozusagen eine dreieckförmige Front-Kontur der Queranschlageinrichtungen 25a, 25b vor die Frontanschlagfläche 20 vor.At a front side of the stop arm 53 facing the workpiece 24, two mutually angled inclined surfaces 74, 75 are arranged, which favor a pivoting of the pivoting part 50 in the direction of the rest position R. Between the two inclined surfaces 74, 75 of the stop arm 53 is preferably rounded. When the pawl-like pivoting parts 50 are pivoted into the stop position A, a triangular front contour of the transverse stop devices 25a, 25b projects in front of the front stop surface 20, as it were.
