Abstract
Description
Beschreibung Die Erfindung betrifft eine Kupplung insbesondere für Mehrfachschrauber. Die Kupplung besteht aus zwei konisch ineinandergreifende Mitnehmer, von denen einer axial in einer Hülse verschiebbar ist.Description The invention relates to a coupling in particular for Multiple screwdrivers. The coupling consists of two conically interlocking drivers, one of which is axially displaceable in a sleeve.
Bekannt sind Ausführungen von Kupplungen für Mehrfachschrauber bei denen der Steckschlüsseleinsatz fest mit der ;Dchrauberspindel verbunden ist, sodaß der Steckschlüssel unter der Kraft des Anzugsmoments der Schraube nur mit großem Kraftaufwand abzuziehen ist. Bei Mehrfach-Schrauber summiert sich dieser Effekt, sodaß in der taxis erhebliche Schwierigkeiten beim Abheben (Rückzug) bestehen und einen raschen Verscllleiß der Werkzeuge mit sich bringt.Versions of couplings for multiple screwdrivers are known which the socket wrench insert is firmly connected to the screwdriver spindle, so that the socket wrench under the force of the tightening torque of the screw only with large Effort is to be deducted. With multiple screwdrivers this effect adds up, so that there are considerable difficulties in taking off (retreating) in taxis and implies rapid wear and tear of the tools.
Es gibt Lösungen die durch Umkehr der Drehrichtung des Schraubers ein Lösen der Verspannung herbeiführen sollen, doch ist dies mit einem erheblichen Aufwand verbunden.There are solutions by reversing the direction of rotation of the screwdriver to bring about a release of the tension, but this is with a considerable amount Effort involved.
ie relativ einfache Lösung bietet die vorliegende Erfindung, wie in der Abbildung beispielsweise dargestellt, die darin besteht, daß die Schrauberspindel (1) mit einem Mitnehmer (2) verbunden tst'der über eine konische @laue (2') in eine konische Nute (3') des Mitnehmers (3) eingreift.The present invention offers the relatively simple solution, as shown in FIG the illustration, for example, which consists in the fact that the screwdriver spindle (1) connected to a driver (2) into a engages conical groove (3 ') of the driver (3).
!)ic Kupplung verbindet mit ihrem Mitnehmer (, einen Steckschlüsseleinsatz (4). Der Mitnehmer (3) ist in der Hülse (6) axial verschiebbar. Durch Zuführen der Schrauberspindel (1) in Pfeilrichtung A wird die Kupplung samt Steckschüsseleinsatz (4) auf die Schraube (5) aufgesetzt und nach Ingangsetzen der Schrauberspindel (1) in das Schlüsselprofil der Schraube (5) eingeführt.!) ic coupling connects with its driver (, a socket wrench insert (4). The driver (3) is axially displaceable in the sleeve (6). By feeding the The screwdriver spindle (1) in the direction of arrow A is the coupling together with the socket insert (4) placed on the screw (5) and after starting the screwdriver spindle (1) inserted into the key profile of the screw (5).
Durch den Aufsetzdruck wird das Spiel zwischen konischer Klaue (2') und oicher Nut (3') aufgehoben, es besteht dadurch eine starre Verbindung zwischen Mitnehmer (3) und Mitnehmer (2) und s<mit auch zwischen Schrauberspindel (1) und Steckschlüsseleinsatz (4).The contact pressure increases the clearance between the conical claw (2 ') and oicher groove (3 ') canceled, there is a rigid connection between Driver (3) and driver (2) and s <with also between screwdriver spindle (1) and socket wrench insert (4).
Nach Erreichen des eingestellten Drehmoments wird der Schraubermotor abgestellt. Das Enddrehmoment bleibt infolge Selbsthemmung zwischen Schrauberspindel (1) und Schraube (5) bestehen. Während des Rückzugs der Schrauberspindel (1) in Richtung B zieht sich der Mitnehmer (2) axial aus dem Mitnehmer (3) aufgrund der konischen Klaue (2') und der konischen Nut (3') um einen geringen Betrag der genügt, die Verspannung zwischen Schrauberspindel (1) und festgezogener Schraube (5) zu lösen. Das Ausfahren des Steckschlüsseleinsatzes (4) aus dem Schlüsselprofi] der Schraube (5) erfolgt somit ohne Kraftaufwand und daher auch verschleißfrei. Bei dem steigenden Einsatz von Mehrfachschraubern in moderne Montagestraßen,gewinnt diese relativ einfache Erfindung an Bedeutung infolge ihrer niedrigen Herstellunge- und Einbaukosten. Auch ist die Kupplung ohne weiteres bereits in Betrieb eingesetzte Mehrfachschrauber einzubauen.After the set torque has been reached, the screwdriver motor will switched off. The final torque remains due to self-locking between the screwdriver spindle (1) and screw (5) exist. During the retraction of the screwdriver spindle (1) in Direction B pulls the driver (2) axially out of the driver (3) due to the conical claw (2 ') and the conical groove (3') by a small amount that is sufficient the tension between the screwdriver spindle (1) and the tightened screw (5) to solve. The extension of the socket wrench insert (4) from the key profile Screw (5) is therefore done without any effort and therefore also wear-free. at the increasing use of multiple screwdrivers in modern assembly lines wins this relatively simple invention in importance due to its low production- and installation costs. The clutch is also already in operation without further ado Multiple screwdrivers to be installed.
