Abstract
Die erfindungsgemäße Werkzeughalterung 3 für eine Handwerkzeugmaschine 1 hat einen stationären Teil 15, 23 und einen drehbaren Teil 17, 19, 20. Der stationäre Teil ist drehfest mit der Handwerkzeugmaschine 1 gekoppelt oder koppelbar. Der drehbare Teil 17, 19, 20 ist mittels einer in dem stationären Teil 15, 23 drehbar gelagerten Kupplung 16 drehfest mit einer Abtriebswelle 9 der Handwerkzeugmaschine 1 gekoppelt oder koppelbar. Ein elektrischer Generator 21 hat ein oder mehrere um die Arbeitsachse 4 angeordnete Permanentmagnete 22 und ein oder mehrere um die Arbeitsachse 4 angeordnete Spulen 24. Die Permanentmagnete 22 sind mit dem stationären Teil 15, 23 und die Spulen 24 mit dem drehbaren Teil 17, 19, 20 verbunden. Ein oder mehreren Lichtquellen 26 in dem drehbaren Teil sind elektrisch, galvanisch mit den Spulen 24 verbunden.The tool holder 3 according to the invention for a hand tool 1 has a stationary part 15, 23 and a rotatable part 17, 19, 20. The stationary part is rotatably coupled to the power tool 1 or coupled. The rotatable member 17, 19, 20 is rotatably coupled by means of a rotatably mounted in the stationary part 15, 23 clutch 16 with an output shaft 9 of the power tool 1 or coupled. An electric generator 21 has one or more permanent magnets 22 arranged around the working axis 4 and one or more coils 24 arranged around the working axis 4. The permanent magnets 22 are connected to the stationary part 15, 23 and the coils 24 to the rotatable part 17, 19, 20 connected. One or more light sources 26 in the rotatable member are electrically connected to the coils 24.
Description
GEBIET DER ERFINDUNGFIELD OF THE INVENTION
Die vorliegende Erfindung betrifft eine Werkzeugmaschine, insbesondere eine handgehaltene Werkzeugmaschine, für drehende Werkzeuge, wie Elektroschrauber, Bohrmaschinen, etc..The present invention relates to a machine tool, in particular a hand-held machine tool, for rotating tools, such as electric screwdrivers, drills, etc ..
OFFENBARUNG DER ERFINDUNGDISCLOSURE OF THE INVENTION
Die erfindungsgemäße Werkzeughalterung für eine Handwerkzeugmaschine hat einen stationären Teil, und einen drehbaren Teil. Der stationäre Teil ist drehfest mit der Handwerkzeugmaschine dauerhaft gekoppelt oder, z.B. mittels einer Befestigungseinrichtung lösbar koppelbar. Der drehbare Teil ist mittels einer in dem stationären Teil drehbar gelagerten Kupplung drehfest mit einer Abtriebswelle der Handwerkzeugmaschine gekoppelt oder koppelbar. Ein elektrischer Generator hat ein oder mehrere um die Arbeitsachse angeordnete Permanentmagnete und ein oder mehrere um die Arbeitsachse angeordnete Spulen. Die Permanentmagnete sind mit dem stationären Teil, und die Spulen mit dem drehbaren Teil verbunden. Die Spulen können sich relativ zu den Permanentmagneten drehen. Ein oder mehreren Lichtquellen in dem drehbaren Teil sind elektrisch, galvanisch mit den Spulen verbunden. Der Generator erzeugt die elektrische Energie für die Beleuchtung. Eine Umverdrahtung innerhalb der Handwerkzeugmaschine kann entfallen.The tool holder according to the invention for a hand tool has a stationary part, and a rotatable part. The stationary part is non-rotatably permanently coupled to the hand tool or, e.g. releasably coupled by means of a fastening device. The rotatable part is non-rotatably coupled or couplable by means of a rotatably mounted in the stationary part coupling with an output shaft of the power tool. An electric generator has one or more permanent magnets arranged around the working axis and one or more coils arranged around the working axis. The permanent magnets are connected to the stationary part, and the coils to the rotatable part. The coils can rotate relative to the permanent magnets. One or more light sources in the rotatable member are electrically connected to the coils. The generator generates the electrical energy for the lighting. A rewiring within the hand tool can be omitted.
