Description
Die Erfindung betrifft ein Spannfutter zum Einspannen vom. Werkzet#gen mit kegelzgeem Schaft, insbesiondiere für Handbiohrmwsichinen, mit im, feiner auf dem Futterkörper verschraubbamen, Überwurfmutter quer zur Werkzeugachse versichieebbiaren, unter Federdruck stehenden Sicherungsgliedern zum Sichern des Werkzeuges gegen Herausfallen und einer lauf der überwurfmutter axial verschiebbaren, die Stellung der Sicherungsglieder beistimmenden Hülste.The invention relates to a chuck for clamping from. Tools with tapered shaft, especially for handheld earmuffs, with im, finer on the chuck body can be screwed, the union nut can be locked transversely to the tool axis, spring-loaded locking elements to secure the tool against falling out and a barrel of the union nut axially displaceable, the position of the locking members matching sleeves.
Es sind SLdherungsvorrichtungen ,gegen Hierausfallen, des Werkzeugeis laus dem Bohrfutter bekannt, die iaws radial zur Biohrbuchse verschiebebiaren Biolzien beistehen, die an ,einer kegelig en Schwfer des Werkzeeugeinsaezes rangreifen und durch eine mit ,einer Kegelfl,äiche versehene, ,axial versichiebbarne Hüllst, in die Sicheruggislage gebracht ,oder aus, ihr freigegeben werden.There are devices to prevent the tools from falling out Known from the drill chuck, the iaws can be shifted radially to the bio-socket stand by who attack and by an axially displaceable envelope provided with a conical surface, in the security situation brought or released from her.
Die Erfindung betrifft nun eine Verhessierung dien bekannten Spannfutter in der Weise, edaß die Sicherungsgbeder Baus, (an beeiden Enden mit einem Kegel Biolzien bestehen, die durch Federn nach ;außen gedrückt werden, woeblei der ;äußere Kegel beeis in Sicherungslage stehender Schiebe,-hülse, in leinte ringförmige Au:s.nehmung der Schiebiehülse eeemastet ist.The invention now relates to a connection with the known chuck in such a way that the safety catches of the building (at both ends with a cone Biologicals exist which are pressed outward by feathers, whereof the; outer Cone with a sliding sleeve or sleeve in the safety position, in a linen ring-shaped recess: see recess the sliding sleeve is masted.
Eine siollche Ausbildung das Spiann:fuitters gewährt insbesondere beeil Heandbohrnl!aschineneine ;größere Sicherung gegen unbeabsichtigtes. Lösen, die durch die besiondere Ausführung der Beoilzen und der mit ihnen zwsammeenwirkenden Teile ,erreicht wird.A special training that Spiann: fuitters grants in particular beeil Heandbohrnl! aschineneine; greater protection against unintentional. To solve, those through the special execution of the Beoilzen and the interactions with them Parts, is achieved.
In der Zeichnung ist der Gegenstand der E.rfindu4g bee2spieilsweisie edargestellt. Es zeigt Abb. i einen Axiallschhitt und Abb. 2 zwei Qwersichmmtte edel Einspiannkopfes bei eingesetztem und gesichertem Werkzeug, und zwar eklen Quuerstt in Höhe -einer Biolzienachse und -einen Q:wensdhnitt in Höhe eines Sitiftes.In the drawing, the subject of E.rfindu4g bee2spieilsweisie e shown. Fig. 1 shows an axial section and Fig. 2 shows two cross sections noble Einspiannkopfes with inserted and secured tool, namely e few Quuerstt at the level of a biological axis and a Q: turning point at the level of a point.
Zur Aufnahme iemes. Werkzeuges i, das ,einen kegeligen Sidhaft z aufweist, dient ein Einspann.-kopf, der laus einer nach unten in, einem Koipf,4 endigenden Büchse 3 besteht, ideren Kopf 4 mit Außieng ewxnde versieben ist, und aus seiner auf diesem Gewinde ,sitzenden überwurfmutter 5. Die Büchse 3 ist zurr Aufnahme dies Werkzeugschaftes 2 mit ieinem Hohlkegel versehen, dessen Kegelwinkel dein des Werkzeugstchafbes z entspricht.For recording iemes. Tool i, which has a conical sidhaft z, serves a clamping head, the laus one down in, a Koipf, 4 ending Bush 3 consists, ideren head 4 is sieved with outside, and from his on this thread, seated union nut 5. The sleeve 3 is to accommodate this Tool shank 2 is provided with a hollow cone, the cone angle of which is that of the tool shank z corresponds to.
In der Überwurfmutter 5 sind ein io-der mehrere Bolzen 6 radial vierschiebbar .,gelagert. Sie stehen unter Wirkung von Fiedern 7, die sie nach außen in ,ausgerückte Stellung zu verschieben suchen, und werden: durch. eine auf der überwurfmutter 5 axial verscMebbare Hülste 8 vor einen Bund ioed. dgl. des Werkzeugschaftes 2 gedrückt, so daiß sie das Werkzeug i verriegeln.In the union nut 5, one or more bolts 6 can be pushed four radially .,stored. They are under the action of feathers 7, which they disengaged outwards Seek position to move, and be: by. one on the union nut 5 axially vercMebbaren sleeve 8 in front of a collar ioed. Like. The tool shaft 2 is pressed, so that they lock the tool i.
Die ldem Werkzeugschaft 2 zugekehrten Enden der Biolzen 6 sänd kegelig ,ausgebildet. Der Bund od. digl. des Werkzeugschaftes z weist eine kegelige Anschlagfläche 9 nüt gleichem Kegelwinkel :auf.The ends of the pins 6 facing the tool shank 2 are conical ,educated. The federal government or digl. the tool shank z has a conical stop surface 9 with the same cone angle: on.
Die lauf der Überwurfmutter 5 ,axial verschiebbare Hülste 8 wird durch Stifte io, z. B. in Form von Schrauben, ;geführt, die in der Überwurfm!wtter 5 sitzen und in Längsschlitze i i der Hülse 8 eingreifen, öderen Versedhiebeweg durch die Längsschlitze i i begrenzt wird.The course of the union nut 5, axially displaceable sleeve 8 is through Pins io, e.g. B. in the form of screws; guided, which sit in the union nut 5 and engage in longitudinal slots i i of the sleeve 8, or the versedhiebeweg through the Longitudinal slots i i is limited.
Der -Klopf 12 .der Bolzen 6 isst kegelig gestadibet, und die Hülse 8 ist im Innfern mit Rasten versehen, die im dargestellten Beispiel .durch eine umlaufende Rille 13 gebüdet werden. Dias die Bolzen 6 steuernde untere Ende der Hülse B ist hohlkegelförmig ausgebildet.The knock 12, the bolt 6 is tapered, and the sleeve 8 is provided with notches in the interior, which in the example shown .by a circumferential groove 13 are gebüdet. Dias the bolts 6 controlling the lower end of the Sleeve B is designed in the shape of a hollow cone.
Wenn edier kEgeliige Teil des Werkzeugschaftes i in die Büchsie 3 dies Einsp,annkopfes leingesteckt isst, wird die zuvor apgehobene Hülste, 8 nach unten geschoben. Ihr hohlkegeligex Teil drückt die Bolzen 6 nach innen ;gegen den Werkzeugschaft z, WO -bni.die Federn 7 zusammengedrückt werden. Die Überwurfmutter 5 wird dann noch mittels ,der Hülste 8 geschraubt, bis. das innere Ende edier Bolzen 6 fest an, der Ansc!hla,-$,äche 9 anliegt.When the conical part of the tool shaft i is inserted into the bush 3 If this Einsp, annkopfes is inserted, the previously raised sleeve, 8 after pushed down. Your hohlkegeligex part presses the bolts 6 inwards; against the Tool shank z, WO -bni.die springs 7 are compressed. The union nut 5 is then still by means of the sleeve 8 screwed until. the inner end of each bolt 6 firmly, the connection terminal - $, surface 9 is in contact.
Um das Werkzeug i ;abzunehmen, braucht man leeglvch :die überwurfmutter 5 durch eine kurze Drehbiewegung ian der Hülse 8 zu lösen, so daß sich .die Anschlagverbindung lockert. Dann wird die Hülse 8 nach soeben geschoben, wodurch die Bolzen 6 durch ihre Federn mach :außen ;gedrückt werden. Damit wird auch der Werkzeugschaft z frei und :das Werkzeug i kann Alus der Büchse 3 des Einspannkopfes in der üblichen Weisse herausgenommen werden.To remove the tool i; you need leeglvch: the union nut 5 to be solved by a short twisting movement ian the sleeve 8, so that .the stop connection loosens. Then the sleeve 8 is just pushed, whereby the bolts 6 through their feathers make: outside; to be pressed. The tool shank z is thus also free and: the tool i can Alus the sleeve 3 of the clamping head in the usual white be taken out.
Holzbeohrmaschinen werden oft für Rechts- und Liniksdreheung gebaut. Auch bei solchen Ausführumqgsformten wirkt die Sichlerung gemäß der Erfintdung.Wood drilling machines are often built for clockwise and linear rotation. In the case of such embodiments, too, the protection works according to the invention.
