Description

Die Erfindung betrifft eine mit einem Bürstenring arbeitende Vorrichtung zum Verhindern des Eindringens von Spänen o. dgl. in die Spindelführung bei Bohrmaschinen mit Lünettführung, insbesondere Zylinderbohrmaschinen. The invention relates to a device for preventing using a brush ring the penetration of chips or the like into the spindle guide in drilling machines with steady rest guides, in particular cylinder drilling machines.

Es ist bereits bekannt, das Eindringen von Staub u. dgl. in Lagerstellen o. dgl. durch umlaufende Abstreifer oder Bürstenringe zu verhindern.It is already known to prevent dust and the like from penetrating into bearings or the like to prevent rotating scrapers or brush rings.

Es ist ferner bekannt, Staub- und Späneabstreifvorrichtungen an Bohrspindeln vorzusehen. It is also known to provide dust and chip scraping devices on drilling spindles.

Mit den bekannten Einrichtungen ist es jedoch nicht möglich, auf die Dauer ein wirksames Abdichten der Bohrspindel, insbesondere an Zylinderbohrmaschinen, durchzuführen. Entweder streifen sie die an der öligen Bohrspindel anhaftenden Staub- und Späneteile nicht restlos ab, oder die stopfbüchsenartig ausgebildeten Abdichtungsmittel führen zu einer vorzeitigen Abnützung der Bohrspindel. With the known devices, however, it is not possible to achieve an effective in the long term Sealing the drilling spindle, in particular on cylinder drilling machines. Either they brush the dust and chips adhering to the oily drill spindle not completely removed, or lead the sealant, which is designed like a stuffing box to premature wear of the drilling spindle.

Man erreicht dagegen ein restloses Abstreifen aller Späneteile o. dgl. unter größtmöglichster Schonung der Bohrspindel, wenn erfindungsgemäß ein Bürstenring die Bohrspindel mit nach innen gerichtetem Bürstenbesatz umgibt und gegenüber der Spindel in Umlauf gesetzt wird.On the other hand, a complete stripping of all chips or the like is achieved under the greatest possible extent Protection of the drilling spindle when, according to the invention, a brush ring is used for the drilling spindle surrounds with inwardly directed brush trim and is set in circulation opposite the spindle.

Dieser Bürstenring kann vom Antrieb der Bohrspindel angetrieben werden. Es kann aber auch ein besonderer Elektromotor für seinen Antrieb vorgesehen sein.This brush ring can be driven by the drive of the drilling spindle. It can but also a special electric motor can be provided for its drive.

Besonders einfach gestaltet sich der Antrieb für den Bürstenring, wenn der ihn umgebende Führungsring als Riemen- oder Friktionsscheibe ausgebildet ist. Der Erfindungsgegenstand ist in einem Ausführungsbeispiel dargestellt.The drive for the brush ring is particularly simple when the one surrounding it Guide ring is designed as a belt or friction disc. The subject matter of the invention is in one embodiment shown.

Die Trommel 3 ist an ihrem äußeren Umfang zur Aufnahme eines Riemens 6 oder eines anderen Übertragungsmittels eingerichtet und wird von dem Motor 7 angetrieben, sobald der Bohrvorgang beendet ist.the rows are attached to it. The brush ring 2 is fastened in the drum 3 and the ring 4. Both parts are rotatably mounted in the stationary housing 5.
The drum 3 is arranged on its outer circumference to receive a belt 6 or other transmission means and is driven by the motor 7 as soon as the drilling process is completed.

Zweckmäßig erfolgt durch eine elektrische Steuerung beim Ausschalten des Bohrspindelantriebes zwangsläufig ein Einschalten des Motors 7. Hat die Bohrspindel 1 eine Drehrichtung im Sinne des Pfeiles B gehabt, so ist eine umgekehrte Drehrichtung des Bürsten-The Bohrspindelantriebes is advantageously effected by an electrical control when turning necessarily a switch on the motor 7. If the drill spindle 1 had a direction of rotation in the direction of arrow B, so a reverse rotation direction of the brush

Dadurch werden die einzelnen schräg liegenden Borsten entsprechend ihrer Lage beansprucht und weitest gehend geschont.: ring 2 required - (marked by arrow A ). As a result, the individual inclined bristles are stressed according to their position and largely protected.

Die an der Bohrspindel 1 anhaftenden Späne werden beim senkrechten Rückgang der stillstehenden Bohrspindel abgebürstet und können durch die Öffnung 8 abfallen. Ein Eindringen in das Bohrspindellager 9 ist ausgeschlossen. The chips adhering to the drilling spindle 1 become the stationary ones during the vertical decline Drill spindle brushed off and can fall off through the opening 8. A Penetration into the drilling spindle bearing 9 is excluded.

Beim Bohren dreht sich die Bohrspindel und die Ringbürste steht still. Nach beendetem Bohren wird die Bohrspindelumdrehung ausgeschaltet und nur der Bürstenring 2 läuft in der Richtung des Pfeiles A. An sich könnte der Bürstenring dauernd umlaufen, da er jedoch -eine zur Bohrspindel entgegengesetzte Drehrichtung hat, würde infolge der somit eintretenden Erhöhung der Bürstengeschwindigkeit eine vorzeitige Abnützung eintreten. Dies soll durch die zeitweise Stillsetzung des Bürstenringes vermieden werden.When drilling, the drill spindle rotates and the ring brush stands still. After drilling is complete, the rotation of the drill spindle is switched off and only the brush ring 2 runs in the direction of arrow A. In itself, the brush ring could rotate continuously, but since it rotates in the opposite direction to the drill spindle, the increase in brush speed would result in premature wear enter. This should be avoided by temporarily stopping the brush ring.
