Abstract

The invention relates to a portable oscillating grinding machine driven by means of an electric motor, in the oscillating plate of which machine suction-extraction passages for any grinding dust arising are arranged. Through-openings provided in the abrasive carrier (abrasive paper, abrasive-coated cloth), which can be clamped securely at both its ends to the base plate, correspond to said suction-extraction passages. In the case of an oscillating grinding machine of this type, it is the object of the invention to perfect the suction-extraction system such that dust suction-extraction in the end-face region of the oscillating plate is also ensured, while maintaining the possibility of grinding over edges. In order to achieve this object, the invention provides for the oscillating plate (3) to be provided, in the region of both its end faces (6, 7), with in each case at least one suction-extraction passage (9, 9') which opens out towards the end face, in which passage a through-hole (12), made in the end regions of the abrasive carrier (10) which run around the end faces of the oscillating plate, can be made to coincide. <IMAGE>

Mittels Elektromotor angetriebener HandschwingschleiferOrbital sander driven by an electric motor

Die Erfindung bezieht sich auf einen mittels eines Elektromotors angetriebenen Handschwingschleifer, in dessen Schwingplatte Absaugkanäle für den anfallenden Schleifstaub angebracht sind, mit denen im an seinen beiden Enden an der Grundplatte festklemmbaren Schleifmittelträger (Schleifpapier, Schleif leinwand) vorgesehene Durchbrechungen korrespondieren.The invention relates to a means of an electric motor powered hand orbital sander, with suction channels for the resulting sanding dust in the vibrating plate those provided in the abrasive carrier (sandpaper, sanding canvas) that can be clamped to the base plate at both ends Corresponding breakthroughs.

Es ist Aufgabe der Erfindung, bei einem derartigen Schwingschleifer das Absaugsystem dahingehend zu vervollkommnen, daß auch eine Staubabsaugung im stirnseitigen Bereich der Schwingplatte bei Erhalt der Möglichkeit des Schleifens über Kante gewährleistet ist.It is the object of the invention in such an orbital sander to perfect the suction system so that also a Dust extraction is guaranteed in the front area of the vibrating plate while maintaining the possibility of grinding over the edge.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Schwing platte im Bereich ihrer beiden Stirnseiten jeweils wenigstens einen zur Stirnseite hin ausmündenden Absaugkanal enthält, mit dem eine in den um die Stirnseiten der Schwingplatte herumgeführten EndbereTchen des Schleifmittelträgers angebrachte Durchbrechung zur Deckung bringbar ist.This object is achieved according to the invention in that the swing plate in the area of its two end faces each contains at least one suction channel opening out towards the end face, with the one opening made in the end areas of the abrasive carrier that are led around the end faces of the vibrating plate can be brought to cover.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Appropriate refinements of the invention are set out in the subclaims specified.

Es sind Schleifmittelträger bekannt, die mit der Schwingplatte durch Klettenverbindung vereinigbar sind. Im Falle der Verwendung derartiger Schleifmittelträger, die etwa bündig mit den Stirnseiten der Schwingplatte abschließen, ist ein Schleifen über "Kante", wie es beispielsweise zum Ausschleifen von Hohlkehlen erforderlich ist, nicht möglich. Außerdem ist ein solches Klettsystem verhältnismäßig teuer.Abrasive carriers are known which can be combined with the vibrating plate by means of Velcro connections. In the case of use such abrasive carriers that are approximately flush with the end faces To finish off the vibrating plate, sanding over an "edge", for example, is used to grind out fillets is required, not possible. In addition, such a Velcro system is relatively expensive.

Wie die Figur 1 erkennen läßt, weist die in bekannter Weise in der Grundplatte ί des Handschwingschleifers2 gelagerte Schwingplatt sowohl im Bereich ihrer beiden Längsseiten 4,5 als auch im Berei ihrer beiden Stirnseiten 6,7 im Abstand voneinander angeordnete Absaugkanäle 8,9 auf, welche sich in die Schwingplatte durchdrin gende Kanäle 8' und 9' fortsetzen. Die Absaugkanäle 8 verlaufen beim Ausführungsbeispiel angenähert quer zu den beiden Läng&ante der Schwingplatte von außen nach innen, desgleichen erstrecken si die Absaugkanäle 9 in den beiden Stirnseiten der Schwingplatte etwa in senkrechter Hauptrichtung zu" diesen von außen nach inneAs can be seen from FIG. 1, the oscillating plate mounted in a known manner in the base plate ί of the manual orbital sander2 both in the area of their two long sides 4,5 and in the area of their two end sides 6,7 arranged at a distance from one another Suction channels 8.9, which continue in the vibrating plate penetrating channels 8 'and 9'. The suction channels 8 run in the exemplary embodiment approximately transversely to the two longitudinal & ante of the vibrating plate from the outside to the inside, likewise the suction channels 9 extend in the two end faces of the vibrating plate approximately in the main perpendicular direction to "these from the outside inwards

Der Schleifmittelträger 10, beispielsweise in Form eines Schleif papiers oder einer Schleif leinwand, ist mit Durchbrechungen 11,1 versehen, die beim Ausführungsbeispiel kreisrund ausgebildet sin Diese Durchbrechungen kommen bei auf die Schwingplatte aufgelegtem Schleifmittelträger zur Deckung mit den korrespondierenden Kanälen 81 und 91 der Schwingplatte.The abrasive backing 10, for example in the form of an abrasive paper or abrasive linen, is provided with openings 11.1, the circular in the embodiment formed sin These perforations are used in the vibrating plate hook abrasive backing to cover with the corresponding channels 8 1 and 9 1 of the Vibrating plate.
