Abstract

Die Erfindung betrifft ein Vorsatzgerät für Handbohrmaschinen und Winkelschleifer im Form eines Schleiffingers. Hierbei ist die in einem U-Bügel mit ausfahrbarem Federstößel gelagerte, am Umfang schwach dachförmige Umlenkrolle mit wenigstens einer mittigen Ringnut versehen, welche das Abgleiten des umlaufenden Schleifbandes verhindert.The invention relates to an attachment for hand drills and angle grinders in the form of a grinding finger. In this case, the weakly roof-shaped deflection roller, which is mounted in a U-bracket with an extensible spring tappet and is circumferentially weak, is provided with at least one central annular groove, which prevents the rotating abrasive belt from sliding off.

Description

Die Erfindung bezieht sich auf ein Vorsatzgerät für Hand­bohrmaschinen und Winkelschleifer in Form eines Schleif­fingers.The invention relates to an attachment for hand drills and angle grinders in the form of a grinding finger.

Nach dem DE-GM 85 34 371 sind solche Vorsatzgeräte be­kannt, bestehend aus einer Antriebsrolle und einer Um­lenkrolle, um welche ein endloses Schleifband geführt ist, mit zwischenliegendem Spannfinger. Hierbei ist u.a. die Seitenführung des Schleifbandes mit Umlenkführung sowie deren Einstellung und Spannung unsicher.According to DE-GM 85 34 371, such attachments are known, consisting of a drive roller and a deflection roller, around which an endless grinding belt is guided, with an intermediate clamping finger. Among other things, the side guide of the sanding belt with deflection guide as well as its adjustment and tension are unsafe.

Zur Vermeidung u.a. auch dieser Nachteile kennzeichnet sich das Vorsatzgerät nach dem Oberbegriff des Anspruchs 1 gemäß der Erfindung dadurch, daß die in einem U-Bügel mit aus­fahrbarem Federstößel gelagerte, am Umfang schwach dach­förmige Umlenkrolle mit wenigstens einer mittigen Ring­nut versehen ist, welche das Abgleiten des umlaufenden Schleifbandes verhindert.To avoid these disadvantages, among other things, the attachment according to the preamble of claim 1 according to the invention is characterized in that the weakly roof-shaped deflection roller, which is mounted in a U-bracket with an extensible spring plunger, is provided with at least one central annular groove which prevents the sliding of the circumferential sanding belt prevented.

Im einzelnen kann hierbei der Federstößel als Vierkant mit gewölbten Seitenflächen in einer entsprechenden Führungs­ausnehmung im Spannfinger laufen, welche beidseits eine Langlochführung mit einerseitigem, teilweise versenkt ge­führtem Schraubkopf und andererseitiger teilweise versenkt geführter und am Schraubbolzen festgelegter Schraubmutter versehen ist, wobei der Schraubbolzen in einem Quergewinde des Federstößels läuft und diesen damit beim Verdrehen zur Einstellung der U-Bügellagerung mit Umlenkrolle auf das umlaufende Schleifband seitlich verstellbar ist.Specifically, the spring plunger can run as a square with curved side surfaces in a corresponding guide recess in the clamping finger, which is provided on both sides with an elongated hole guide with a screw head on one side, partially countersunk, and on the other hand a partially countersunk screw nut fixed on the screw bolt, the screw bolt being in a transverse thread of the Spring plunger runs and can thus be adjusted laterally when rotating to adjust the U-bracket bearing with deflection roller on the rotating sanding belt.

Weitere Einzelheiten sind sodann anhand der Zeichnung an einem bevorzugten Ausführungsbeispiel eines Vorsatzgerätes gemäß der Erfindung dargestellt und nachfolgend beschrieben und zwar zeigen:

  • Figur 1 die perspektivische Ansicht eines Vorsatzge­rätes gemäß der Erfindung,
  • Figur 2 den Schnitt nach Linie II - II der Figur 1 und
  • Figur 3 die Ansicht der Umlenkrolle.
Further details are then shown with reference to the drawing of a preferred embodiment of an attachment according to the invention and described below, showing:
  • FIG. 1 shows the perspective view of a front attachment according to the invention,
  • Figure 2 shows the section along line II - II of Figure 1 and
  • Figure 3 shows the view of the guide roller.

Wie aus der Zeichnung ersichtlich wird, besteht das Vor­satzgerät für Handbohrmaschinen 1 und Winkelschleifer in Form eines Schleiffingers aus einer Antriebsrolle 2 und einer Umlenkrolle 3, um welche (3) ein endloses Schleif­band 4 geführt ist, mit zwischenliegendem Spannfinger 5. Die Umlenkrolle 3 ist in einem U-Bügel 6 mit ausfahrbarem Federstößel 7 gelagert, am Umfang schwach dachförmig und hier mit einer mittigen Ringnut 8 versehen, welche das Ab­gleiten des umlaufenden Schleifbandes 4 verhindert.As can be seen from the drawing, the attachment for hand drills 1 and angle grinders in the form of a sanding finger consists of a drive roller 2 and a deflection roller 3, around which (3) an endless sanding belt 4 is guided, with an intermediate clamping finger 5. The deflection roller 3 is in a U-bracket 6 with extendable spring plunger 7 mounted, slightly roof-shaped on the circumference and here provided with a central annular groove 8, which prevents the rotating abrasive belt 4 from sliding off.

Der Federstößel 7 läuft als Vierkant mit gewölbten Seiten­flächen in einer entsprechenden Führungsausnehmung 9 im Spannfinger 5, welche beidseits eine Langlochführung 10 mit einerseitig geführtem Schraubkopf 11 und anderseitig geführter und am Schraubbolzen 12 festgelegter Schraubmut­ter 13 aufweist. Hierbei läuft der Schraubbolzen 12 in ei­nem Quergewinde 14 des Federstößels 7 und macht diesen (7) damit beim Verdrehen zur Einstellung der U-Bügellagerung 6 mit Umlenkrolle 3 auf das umlaufende Schleifband 4 seit­lich verstellbar.The spring plunger 7 runs as a square with curved side surfaces in a corresponding guide recess 9 in the clamping finger 5, which has an elongated hole guide 10 on both sides with a screw head 11 guided on one side and a screw nut 13 guided on the other side and fixed on the screw bolt 12. Here, the screw bolt 12 runs in a transverse thread 14 of the spring plunger 7 and thus makes this (7) laterally adjustable when rotating to adjust the U-bracket bearing 6 with deflection roller 3 on the rotating grinding belt 4.

Im übrigen ist am Spannfinger 5 mindestens einerseits ein Metallstreifen 15 mit Gummi- oder Kunststoffunterlage 16 zur Auflageführung des Schleifbandes 4 fest aufgebracht. Die Antriebsrolle 2 ist als auf das Endgewinde der Antriebs­welle 17 der Handbohrmaschine 1 oder des Winkelschleifers aufschraubbare Gummi- oder Kunststoffrolle ausgebildet.In addition, a metal strip 15 with a rubber or plastic base 16 for supporting the abrasive belt 4 is firmly attached to the tension finger 5 at least on the one hand. The drive roller 2 is designed as a rubber or plastic roller that can be screwed onto the end thread of the drive shaft 17 of the hand drill 1 or of the angle grinder.

Das Anschlußstück mit Aufnahme für die Antriebsrolle 2 im U-förmigen Handschutz 18 ist als Spannflansch 19 zur Be­festigung am Bohrmaschinen- oder Winkelschleiferhals 20 ausgebildet und trägt seitlich einen Grillknopf 21.The connector with receptacle for the drive roller 2 in the U-shaped hand guard 18 is designed as a clamping flange 19 for attachment to the drill or angle grinder neck 20 and carries a grill button 21 on the side.
