Die Aufgabe der Erfindung besteht in der Realisierung einer möglichst staubdichten Handwerkzeugmaschine mit einer Schlagwerkzeugaufnahme.The object of the invention consists in the realization of a dust-tight as possible hand tool machine with a Schlagwerkzeugaufnahme.
Die Aufgabe wird im Wesentlichen durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.The object is essentially achieved by the features of claim 1. Advantageous developments emerge from the subclaims.
So weist eine Handwerkzeugmaschine, mit welcher zumindest teilweise ein Werkzeug längs einer Schlagachse schlagend antreibbar ist, eine Schlagwerkzeugaufnahme und eine Arbeitsspindel auf, in welcher eine zumindest einseitig offene Aufnahmehülse drehfest sowie axial begrenzt beweglich gelagert ist, in der zumindest ein Verriegelungselement für ein in die Aufnahmehülse einführbares Einsteckende des Werkzeuges radial versetzbar gelagert ist, wobei die Aufnahmehülse an einem Ende durch einen in ihr festgelegten, axial überstehenden Döpper verschlossen ist.Thus, a hand tool, with which at least partially a tool along a striking axis is driven to beat, a striking tool and a work spindle, in which an at least unilaterally open receiving sleeve rotatably and axially limited movably mounted in the at least one locking element for a in the receiving sleeve insertable end of the tool is mounted radially displaceable, wherein the receiving sleeve is closed at one end by a fixed in her, axially projecting striker.
Durch den maschinenseitig die Aufnahmehülse verschliessenden, festgelegten Döpper sind beide zusammen topfförmig geschlossen ausgebildet, wodurch ein Eindringen von Staub in das Maschineninnere verhindert wird.By the machine side, the receiving sleeve closing, fixed anvil are both together cup-shaped closed, whereby penetration of dust into the machine interior is prevented.
Der Döpper ist durch eine elastische Zwischenschicht, bspw. eine Vulkanisation, elastisch in der Aufnahmehülse elastisch festgelegt, wodurch auf das freie Ende des Döppers aufgebrachte Schlagimpulse von der Aufnahmehülse weitgehend entkoppelt sind und somit nahezu völlständig auf das Schlagwerkzeug übertragen werden.The striker is elastically fixed in the receiving sleeve by an elastic intermediate layer, eg. Vulcanization, whereby impact pulses applied to the free end of the striker are largely decoupled from the receiving sleeve and thus almost completely transferred to the impact tool.
Vorteilhaft ist die werkzeugseitige Stirnseite des Döppers ballig ausgebildet, wodurch lagetolerant ein zentraler Kraftstoss auf ein In der Aufnahmehülse aufgenommenes Einsteckende erfolgen kann.Advantageously, the tool-side end face of the anvil is formed crowned, which can tolerate a lag moment tolerant to a recorded in the receiving sleeve insertion end can be done.
Vorteilhaft bildet die Aufnahmehülse maschinenseitig radial aussen, sich axial und radial ersteckende Drehmitnahmeflügel aus, welche in passend zugeordnete Spindelnuten der Arbeitsspindel eingreifen, wodurch die Aufnahmehülse drehfest und axial begrenzt beweglich mit der Arbeitsspindel verbunden ist.Advantageously, the receiving sleeve forms the machine side radially outward, axially and radially ersteckende rotary driving wing, which engage in appropriately associated spindle grooves of the work spindle, whereby the receiving sleeve is rotatably and axially limited movably connected to the work spindle.
Vorteilhaft bildet die Aufnahmehülse radial innen, sich axial und radial ersteckende Drehmitnahmestege aus, in welche passend zugeordnete Drehmitnahmenuten des Einsteckendes eingreifen, wodurch das Einsteckende drehfest mit der Aufnahmehülse verbunden ist.Advantageously, the receiving sleeve radially inside, axially and radially ersteckende Drehmitnahmestege, in which matingly associated rotary driving grooves of the insertion engage, whereby the insertion end is rotatably connected to the receiving sleeve.
Vorteilhaft ist in der Aufnahmehülse zumindest ein Verriegelungselement, weiter vorteilhaft eine Verriegelungskugel, radial versetzbar gelagert, wodurch ein in dieser aufgenommenes Werkzeug axial verriegelbar ist. Wenn das Werkzeug zugeordnete längliche Verriegelungsnuten ausbildet, ist es axial begrenzt beweglich. Entspricht hingegen die Form der Verriegelungsausnehmung der Form des Verriegelungselements, bspw. die einer Kugelkalotte zu einer Verriegelungskugel, ist es axial fixiert.Advantageously, in the receiving sleeve at least one locking element, further advantageously a locking ball, mounted radially displaceable, whereby a recorded in this tool is axially locked. When the tool forms associated elongated locking grooves, it is axially limited movable. If, in contrast, the shape of the locking recess corresponds to the shape of the locking element, for example, that of a spherical cap to a locking ball, it is axially fixed.
Vorteilhaft ist dem Verriegelungselement radial aussen ein versetzbares Arretiermittel zugeordnet, weiter vorteilhaft eine Arretierhülse, wodurch die Verriegelung des Werkzeugs in der Aufnahmehülse arretiert werden kann.Advantageously, the locking element radially outwardly assigned a displaceable locking means, further advantageously a locking sleeve, whereby the locking of the tool can be locked in the receiving sleeve.
Vorteilhaft ist das Arretiermittel über ein Federmittel federnd gegen die Aufnahmehülse vorgespannt, weiter vorteilhaft über eine Spiralfeder, wodurch das Arretiermittel selbstarretierend ausgebildet ist.Advantageously, the locking means is resiliently biased by a spring means against the receiving sleeve, further advantageously via a spiral spring, whereby the locking means is formed self-locking.
Vorteilhaft ist die begrenzt axial bewegliche Aufnahmehülse gegenüber der Arbeitsspindel mit einem Dichtmittel staubdicht abgedichtet, weiter vorteilhaft über eine Membrandichtung, die zumindest einen axialen Faltenwurf aufweist, wodurch eine hinreichend grosse Axialbewegung ermüdungsfrei abgedichtet wird.Advantageously, the limited axially movable receiving sleeve with respect to the work spindle with a sealant sealed dustproof, further advantageous via a diaphragm seal, which has at least one axial fold, whereby a sufficiently large axial movement is sealed fatigue-free.
Vorteilhaft ist die Membrandichtung mit einem Ende an einem Federtopf befestigt, der selbst staubdicht an der Aufnahmehülse fixiert ist, bspw. über einen O-Ring, wodurch die axiale Baulänge der Schlagwerkzeugaufnahme verkürzt ist.Advantageously, the membrane seal is attached at one end to a spring cup, which is itself fixed dust-tight to the receiving sleeve, for example. Via an O-ring, whereby the axial length of the impact tool receptacle is shortened.
