Abstract
Eine Handwerkzeugmaschine ist mit einem Schlagwerk ausgestattet, das einen in einem Führungsrohr (2) axial hin und her beweglichen Schläger (1) aufweist, wobei ein eine Kraft auf den Schläger (1) ausübender Federmechanismus (4) vorhanden ist, womit der Schläger (1) in eine Bewegung in Richtung auf ein in der Handwerkzeugmaschine einsteckbares Werkzeug (3) versetzbar ist. Das Schlagwerkzeug erzeugt bei einer relativ kleinen Schlagfrequenz eine sehr hohe Einzelschlagenergie dadurch, dass der Schläger (1) nach jedem Schlag in eine Bewegung gegen die Kraft des Federmechanismus (4) versetzt wird, um diesen zu spannen, und dass der Schläger (1) nach dem Spannen des Federmechanismus (4) schlagartig wieder freigegeben wird, so dass er in Richtung des Werkzeugs (3) fliegt.A portable power tool is equipped with a percussion mechanism having a racket (1) axially reciprocating in a guide tube (2), a spring mechanism (4) exerting a force on the racket (1), whereby the racket (1 ) can be displaced into a movement in the direction of a tool (3) which can be inserted in the handheld power tool. The impact tool generates at a relatively small impact frequency very high single impact energy by the club (1) after each stroke in a movement against the force of the spring mechanism (4) is added to tension this, and that the bat (1) after the tensioning of the spring mechanism (4) is released suddenly, so that it flies in the direction of the tool (3).
Description
Die vorliegende Erfindung betrifft eine Handwerkzeugmaschine – vorzugsweise einen Bohr- und/oder Schlaghammer- mit einem Schlagwerk, das einen in einem Führungsrohr axial hin und her beweglichen Schläger aufweist, wobei ein eine Kraft auf den Schläger ausübender Federmechanismus vorhanden ist, womit der Schläger in eine Bewegung in Richtung auf ein in der Handwerkzeugmaschine einsteckbares Werkzeug versetzbar ist.The The present invention relates to a hand tool - preferably a drill and / or percussion hammer with a striking mechanism, the one in a guide tube axially reciprocally movable racket, wherein a one Power on the racket a performing Spring mechanism is present, bringing the racket in a movement in the direction be displaced to a plug-in tool in the power tool is.
Ein
derartiges repetierende Schlagbewegungen ausführendes Kompressionsschlagwerk
für einen
elektropneumatischen Bohr- und/oder Schlaghammer besteht, wie aus
der
Der Erfindung liegt nun die Aufgabe zugrunde, ein Schlagwerk der eingangs genannten Art anzugeben, das mit möglichst einfachen technischen Mitteln realisierbar ist und mit denen eine große Einzelschlagenergie bei kleiner Schlagfrequenz realisierbar ist.Of the Invention is the object of a striking mechanism of the beginning specify the type mentioned, with the simplest possible technical means is realizable and with which a large single impact energy at small beat frequency is feasible.
Vorteile der ErfindungAdvantages of invention
Die genannte Aufgabe wird mit den Merkmalen des Anspruchs 1 dadurch gelöst, dass Mittel vorhanden sind, welche den Schläger nach jedem Schlag in eine Bewegung gegen die Kraft eines Federmechanismus versetzen, um diesen zu spannen, und dass die Mittel den Schläger nach dem Spannen des Federmechanismus schlagartig wieder freigeben, so dass er, durch den Federmechanismus angetrieben, in Richtung des Werkzeugs fliegt. Dadurch, dass der Schläger nach jedem Schlag aktiv gegen die Kraft des Federmechanismus bewegt wird, erhält der Schläger nach anschließender Freigabe für einen neuen Schlag eine sehr hohe Energie.The said object is characterized by the features of claim 1 solved, that means are present which the bat after each stroke in a Move against the force of a spring mechanism to this to tension, and that means the racket after tensioning the spring mechanism abruptly release it, allowing it, through the spring mechanism driven, flying in the direction of the tool. Because of that bat actively moved against the force of the spring mechanism after each stroke will get that bat after subsequent Released for a new blow a very high energy.
Vorteilhafte Ausführungen der Erfindung gehen aus den Unteransprüchen hervor.advantageous versions The invention will become apparent from the dependent claims.
Ein zweckmäßiger Antrieb für den Schläger stellt eine kraftschlüssige Verbindung mit dem Schläger nach einem ausgeübten Schlag her und bewegt ihn gegen die Kraft des Federmechanismus und löst die kraftschlüssige Verbindung wieder, sobald der Schläger in seine Bewegung gegen die Kraft des Federmechanismus eine bestimmte Position erreicht hat.One appropriate drive for the Racket poses a non-positive Connection with the bat after an exercise Hit it and move it against the force of the spring mechanism and solve the frictional Reconnect once the bat is in its movement against the force of the spring mechanism has reached a certain position.
Ein vorteilhafter Federmechanismus besteht aus einem mit einem kompressionsfähigen Medium gefüllten Druckspeicherraum, der sich auf der dem Werkzeug abgewandten Seite des Schlägers im Führungsrohr befindet. Der Druckspeicherraum kann mit einem Gas, vorzugsweise Luft, oder auch einer Flüssigkeit gefüllt sein. Das kompressionsfähige Medium – Gas oder Flüssigkeit – verbleibt ständig im Druckspeicherraum und es müssen nur gewisse Leckverluste aus dem Druckspeicherraum ausgeglichen werden. Dazu kann eine Pumpe vorgesehen werden, die dem Druckspeicherraum kompressionsfähiges Medium zum Ausgleich von Leckverlusten zuführt. Die Pumpleistung dieser Pumpe kann sehr gering sein, weil eben nur Leckverluste im Druckspeicherraum ausgeglichen werden müssen. Eine solche kleine, wenig Volumen und Gewicht erfordernde Pumpe kann in der Handwerkzeugmaschine integriert werden.One Advantageous spring mechanism consists of a filled with a compressible medium pressure storage space, the on the side facing away from the tool of the racket in guide tube located. The pressure storage space can with a gas, preferably Air, or even a liquid filled be. The compressible Medium - gas or liquid - remains constantly in the pressure storage room and it must only certain leakage from the accumulator space balanced become. For this purpose, a pump may be provided which the pressure storage space compression enabled Supplies medium to compensate for leakage. The pumping power of this Pump can be very low, because just compensated for leakage in the accumulator chamber Need to become. Such a small, little volume and weight requiring pump can be integrated in the power tool.
Ein anderer vorteilhafter Federmechanismus kann aus einer oder mehreren Druckfedern und/oder Zugfedern bestehen, die sich einerseits am Schläger und andererseits an einer in Bewegungsrichtung des Schlägers festen Schulter abstützen.One another advantageous spring mechanism may consist of one or more Compression springs and / or tension springs exist, on the one hand am Rackets and on the other hand fixed to a direction of movement of the racket Support the shoulder.
