Abstract

The subject of the invention is a portable orbital sander driven by an electric motor and with sanding dust which can be drawn into the fan space by a fan via openings in the abrasive carrier and in the baseplate as well as via apertures in a housing part which are connected to the openings in the baseplate by orbital air-guiding ducts, which sanding dust can be blown out again through a duct which adjoins the fan space and opens into a connecting piece for a dust-collecting container. In order to be able to produce an orbital sander of this type in a simpler and more cost-effective manner, in view of its device for drawing off the sanding dust, it is proposed according to the invention that the fan space (1), the suction apertures (21) in the housing and the connecting piece (19) for the dust container be the constituent parts of a two-shelled complete housing for the orbital sander (Fig. 1). <IMAGE>

■---■' ' ; Elektromotorisch angetriebener Handschwingschleifer ■ --- ■ ''; Orbital sander driven by an electric motor

Gegenstand der Erfindung ist ein elektromotorisch angetriebener HandschwJngschleifer mit durch einen Ventilator über Ausnehmungen im Schleifmittelträger und in der Bodenplatte sowie über Öffnungen in einem Gehäuseteil, welche mit den Ausnehmungen in der Bodenplatte durch schwingbewegliche Luftleitkanäle verbunden sind, in den Ventilatorraum einsaugbarem Schleifstaub, der durch einen sich an den Ventilatorraum anschließenden, in einen Anschlußstutzen für ein Staubauffangbehältnis mündenden Kanal wieder ausblasbar ist.The subject of the invention is an electric motor-driven manual swing grinder with recesses provided by a fan in the abrasive carrier and in the base plate as well as via openings in a housing part, which are connected to the recesses in the base plate by air ducts that can oscillate, in the Sanding dust that can be sucked in through the fan chamber adjoining the fan room into a connecting piece can be blown out again for a dust collector opening duct is.

Bei bekannten Handschwingschleifern dieser Art ist der Saug- bzw. Ventilatorraum in einem separaten, vom Motorteil getrennten Druckgußgehäuse untergebracht. Eine derartige Konzeption.. verursacht sowohl hinsichtlich der Anzahl der benötigten Bauteile als auch im Hinblick auf die Teilebearbeitung und Montage einen verhältnismäßig erheblichen Aufwand.In known hand orbital sander of this type, the suction or fan room in a separate, separate from the motor part Die-cast housing housed. Such a concept .. causes both in terms of the number of components required as well as a relatively considerable effort in terms of parts processing and assembly.

Es ist Aufgabe der Erfindung, einen elektromotorisch angetriebenen Handschwingschleifer zu schaffen, der im Rahmen seiner Einrichtung zum Absaugen des Schleifstaubs vergleichsweise einfacher und kostengünstiger wird.It is the object of the invention to provide an electric motor driven Orbital sander to create, which is comparatively easier in the context of its device for suctioning off the sanding dust and becomes cheaper.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß der Ventilatorraum, die Ansaugöffnungen im Gehäuse sowie uer Anschlußstutzen f^ündiasi Staubauf fäing b'elh äii tlnil si ' Bestandteile eines zweischalig ausgebildeten Gesamtgehäuses für den Schwingschleifer sind.According to the invention, this object is achieved in that the fan chamber, the suction openings in the housing and the outer connecting pieces for dust collecting are part of a two-shell overall housing for the orbital sander.

Wie die Figuren 1 und 2 erkennen lassen, wird der .spiralförmige Ventilatorraum 1 seitlich durch gekrümmte Wandungen 2 und 2\ nach oben durch die Wandungen 4,4' und nach unten durch die Wandüngen 5,5' des aus zwei Schalen 6,6' bestehenden Schwingschleifergehäuses 7 abgegrenzt. Die Trennlinie der beiden Gehäuseschalen ist in Fig. 2 mit 8 bezeichnet.As can be seen in FIGS. 1 and 2, the .spiral-shaped fan space 1 is laterally formed by curved walls 2 and 2 \ upwards through the walls 4,4 'and downwards through the walls 5,5' of the two shells 6,6 ' existing orbital sander housing 7 delimited. The dividing line between the two housing shells is denoted by 8 in FIG. 2.

Im Ventilatorraum befindet sich der Ventilator 9, der auf der Antriebswelle 10 für die Bodenplatte 11 angebracht ist. Die in einem nicht dargestellten oberen und in einem unteren Kugellager 12 drehbar gelagerte Antriebswelle 10 wird durch den Antriebsmotor in Drehung versetzt. ; Die während des Betriebs des Schwingschleifers eine Schwingbewegung ausführende, im Kugellager 13 gelagerte Bodenplatte 11 ist mittels Gummielemente 14 oder dergl. Bauteile beweglich in an der Oberseite der Bodenplatte 11 sowie in an der Unterseite des Schwingschleifergehäuses vorgesehenen Aufnahmen 15 und 15' abgestützt. ν 'The fan 9, which is attached to the drive shaft 10 for the base plate 11, is located in the fan compartment. The drive shaft 10, which is rotatably supported in an upper ball bearing 12, not shown, is set in rotation by the drive motor. ; The base plate 11, which executes an oscillating movement during operation of the orbital sander and is mounted in the ball bearing 13, is movably supported by means of rubber elements 14 or similar components in receptacles 15 and 15 'provided on the top of the base plate 11 and on the underside of the orbital sander housing. ν '

An den Ventilatorraum 1 schließt sich etwa tangential ein Ausblaskanal 16 an, der durch die Wandungen 17 und 17'der beiden Gehäuseteile gebildet ist und in einen Anschlußstutzen 19 für ein Staubauffangbehältnis ,20 mündet.A blow-out duct closes approximately tangentially on the fan chamber 1 16, which is formed by the walls 17 and 17 'of the two housing parts and in a connection piece 19 for a dust container, 20 opens.

ES 83/27 E S 83/27

Die den Ventilatorraum 1 nach unten begrenzenden Wandungen 5 und b1 der beiden Gehäuseschalen weisen Ansaugöffnungen 21 und 21' auf und bilden zusammen mit den Abschlußwänden 23,24 Luftströmungskanäle 25,26, in welche elastisch nachgiebig ausgebildete Stutzen 27,28 münden, welche die Schwingbewegung der Bodenplatte 11 mitmachen und die Strömungsverbindung zu den Ausnehmungen 29 in der Bodenplatte über Kanäle 30 herstellen (vergl."hierzu Fig. 3). Mit den Ausnehmungen 29 in der Bodenplatte 11 wirken wiederum die etwa deckungsgleich dazu liegenden Ausnehmungen 31 im Schleifmittelträger 32 zusammen. The walls 5 and b 1 of the two housing shells that delimit the fan chamber 1 downwardly have suction openings 21 and 21 'and, together with the end walls 23, 24, form air flow channels 25, 26 into which elastically flexible nozzles 27, 28 open, which cause the oscillating movement of the base plate 11 and establish the flow connection to the recesses 29 in the base plate via channels 30 (see FIG. 3).

Während des Betriebs des Schwingschleifers wird demgemäß der anfallende Schleifstaub durch die Ausnehmungen 31 im Schleifmittelträger und die mit diesen korrespondierenden Ausnehmungen 29 in der Bodenplatte 11 in das Innere der Stutzen 27 und eingesaugt und gelangt über diese in den Ventilatorraum 1. Durch die Wirkung des Ventilators 9 wird der Schleifstaub über den Ausblaskanal 16 und den Anschlußstutzen 19 in das Sitaubauffangbehältnis 20 geblasen.During the operation of the orbital sander is accordingly the Accruing grinding dust through the recesses 31 in the abrasive carrier and the recesses corresponding to these 29 in the base plate 11 into the interior of the nozzle 27 and sucked in and passes through this into the fan chamber 1. Through the action of the fan 9 is the grinding dust via the exhaust duct 16 and the connecting piece 19 in the Sitaubauffangbehältnis 20 blown.

Durch die erfindungsgemäße Maßnahme sind somit sämtliche an der Schwingbewegung der Bodenplatte nicht betätigbaren Bauteile in einem Kunststoffgehäuse untergebracht bzw. in das Gehäuse integriert. By the measure according to the invention, all of the Oscillating movement of the base plate housed non-actuatable components in a plastic housing or integrated into the housing.
