Description
Die Erfindung geht aus von einer Handwerkzeugmaschinenhaltevorrichtung nach dem Oberbegriff des Anspruchs 1, der auch aus der
Es sind Bohr- und Meißelhammerhaltevorrichtungen bekannt, die ein Hammerrohr und Sperrkörper aufweisen, die in montiertem Zustand das Hammerrohr mit einem Werkzeugfutter verbinden.Drill and chisel hammers are known which comprise a hammer tube and locking bodies which, when assembled, connect the hammer tube to a tool chuck.
Die
Die Erfindung geht aus von einer Handwerkzeugmaschinenhaltevorrichtung, insbesondere einer Bohr- und/oder Meißelhammerhaltevorrichtung, mit einem Hammerrohr und wenigstens einem Sperrkörper, der in einem montierten Zustand das Hammerrohr mit zumindest einem weiteren Haltebauteil verbindet. Der wenigstens eine Sperrkörper weist wenigstens eine um wenigstens eine Belastungskippachse gekrümmte Sperrfläche und im montierten Zustand betrachtet in radialer Richtung des Hammerrohrs eine größere Erstreckung auf, als in axialer Richtung des Hammerrohrs. Dabei soll unter einem "Hammerrohr" insbesondere ein langgestrecktes, hohles Bauteil, insbesondere eine Hohlwelle, verstanden werden, in dem ein Schläger eines Schlagwerks, ein Kolben, insbesondere ein Topfkolben, und/oder ein mit einem Schläger zusammenwirkender Schlagbolzen in Längserstreckung des Hammerrohrs geführt ist.The invention relates to a portable power tool holding device, in particular a drilling and / or chisel hammer holding device, with a hammer tube and at least one locking body which connects the hammer tube with at least one further holding member in an assembled state. The at least one blocking body has at least one locking surface curved around at least one load-tilting axis and, viewed in the mounted state, has a greater extent in the radial direction of the hammer tube than in the axial direction of the hammer tube. In this case, a "hammer tube" is to be understood in particular as an elongated, hollow component, in particular a hollow shaft, in which a racket of a percussion mechanism, a piston, in particular a pot piston, and / or a striker cooperating with a striker in the longitudinal extent of the hammer tube is performed.
Die Belastungskippachse ist eine Achse, um die der Sperrkörper bei einer Belastung des Hammerrohrs und/oder des mit dem Hammerrohr zu verbindenden Haltebauteils in axialer Richtung und/oder in Umfangsrichtung des Hammerrohrs verkippt wird, wobei das zumindest eine weitere Bauteil eine mit der gekrümmten Sperrfläche in zumindest einem Betriebszustand korrespondierende, gekrümmte Haltefläche aufweist. Durch eine entsprechende Ausgestaltung können vorteilhaft große tragende Flächen, kleine Flächenpressungen, geringer Verschleiß und eine lange Lebensdauer erzielt werden.The load tilting axis is an axis about which the locking body is tilted in the axial direction and / or in the circumferential direction of the hammer tube when the hammer tube and / or the holding member to be connected to the hammer tube is loaded, the at least one further component having a curved blocking surface in FIG Having at least one operating state corresponding curved support surface.

Die Sperrfläche kann dabei verschiedene, dem Fachmann als sinnvoll erscheinende Krümmungen aufweisen und auch durch verschiedene, dem Fachmann als sinnvoll erscheinende Verfahren hergestellt sein, wie mittels spanenden Umformverfahren, z.B. Fräsverfahren. Besonders vorteilhaft ist die Sperrfläche jedoch zumindest teilweise von einer bombierten, d.h. durch einen plastischen Verformungsvorgang hergestellten Fläche gebildet, wie insbesondere durch einen Walzvorgang, wodurch die Lebensdauer weiter gesteigert werden kann. Die Sperrfläche des Sperrkörpers kann grundsätzlich zumindest teilweise und vorzugsweise vollständig konvex ausgebildet sein.The blocking surface may in this case have various curvatures that appear appropriate to the person skilled in the art and may also be produced by various processes that appear appropriate to the person skilled in the art, such as by means of cutting forming processes, e.g. Milling process. However, the blocking surface is particularly advantageous at least partially by a domed, i. formed by a plastic deformation process surface, in particular by a rolling process, whereby the life can be further increased. The blocking surface of the blocking body may in principle be at least partially and preferably completely convex.

Weist die Handwerkzeugmaschinenhaltevorrichtung jedoch einen Werkzeughalter mit wenigstens einer in zumindest einem Betriebszustand mit dem Sperrkörper korrespondierenden Haltefläche auf, kann eine besonders Platz sparende Konstruktion, insbesondere ohne zusätzlichen Halteflansch, erreicht werden. Unter einem "Werkzeughalter" soll in diesem Zusammenhang insbesondere ein Bauteil verstanden werden, das einen Aufnahmebereich für ein Einsatzwerkzeug, wie insbesondere für einen Bohrer und/oder Meißel, aufweist.By means of one or more corresponding blocking bodies, various components of the hand-held power tool holding device that appear appropriate to the person skilled in the art can be connected to the hammer tube. However, if the handheld power tool holding device has a tool holder with at least one holding surface corresponding to the blocking body in at least one operating state, a particularly space-saving design, in particular without an additional holding flange, can be achieved. A "tool holder" is to be understood in this context, in particular a component having a receiving area for an insert tool, in particular for a drill and / or chisel.

Der Sperrkörper kann grundsätzlich verschiedene, dem Fachmann als sinnvoll erscheinende Formen aufweisen, wobei dann entsprechend angepasste Gegenflächen vorgesehen sein sollten.The blocking body may in principle have different shapes that appear appropriate to the person skilled in the art, in which case correspondingly adapted opposing surfaces should then be provided.
