Abstract
Ein Handschleifmaschine (10) mit Staubabsaugung, mit einem am Gehäuse (12) drehend oder schwingend antreibbar angeordneten Schleifteller (26), ist dadurch einfach und kostengünstig herstellbar und betreibbar, dass zum Antrieb des Schleiftellers (26) sowie zur Erzeugung des Absaugluftstromes allein der Luftstrom eines insbesondere handelsüblichen Staubsaugers (42) dient.A hand-held grinding machine (10) with dust extraction, with a grinding plate (26) which can be driven to rotate or swing on the housing (12), is simple and inexpensive to produce and operate in such a way that only the air flow is used to drive the grinding plate (26) and to generate the suction air flow of a particularly commercially available vacuum cleaner (42).
Description
Stand der TechnikState of the art
Die vorliegende Erfindung geht aus von einer Handschleifmaschine nach dem Oberbegriff des Anspruchs 1.The present invention starts out from a hand grinder according to the preamble of the claim 1.
Zum Schleifen von Werkstücken sind Handwerkzeugmaschinen mit Elektro- oder Druckluftantrieb bekannt. Das Drehmoment der Luftdruck- bzw. Elektromotoren wird auf die Schleifplatte oder Schleifteller übertragen und ermöglicht eine entsprechende Spanabtragung.For grinding workpieces Hand machine tools with electric or compressed air drive are known. The torque of the air pressure or electric motors is on the grinding plate or transfer grinding disc and enables a corresponding chip removal.
Die dabei entstehenden Späne bzw. der Schleifstaub wird entweder mittels Eigenabsaugung durch einen gemeinsam mit dem Motor drehenden Absaugventilator in einen mit der Handwerkzeugmaschine gekuppelten Staubbehälter geblasen oder mittels Fremdabsaugung durch einen geeigneten Staubsauger abtransportiert. Dabei sind die für die Fremdabsaugung verwendeten Staubsauger in den meisten Fällen für das Absaugen von Schleifstaub allein überdimensioniert. So stehen etwa 1400 Watt Aufnahmeleistung des Staubsaugers etwa 300 Watt Aufnahmeleistung der Handschleifmaschine gegenüber. Damit wird die Leistung des Staubsaugers nur unzureichend genutzt.The resulting chips or the grinding dust is either extracted by a self-extractor together with the motor rotating suction fan in one the handheld power tool coupled blown or by means of External suction removed using a suitable vacuum cleaner. The are for the external suction used in most cases for suction oversized by grinding dust alone. So there is about 1400 watts of power consumption of the vacuum cleaner 300 watt power consumption of the hand grinder compared. In order to the performance of the vacuum cleaner is used insufficiently.
Es sind Staubsaugerzubehörgeräte bekannt, die mit dem Absaugluftstrom über einen Antriebsventilator betätigte rotierende Bürsten enthalten und insbesondere für die Bearbeitung von textilen Fußbodenbelägen vorgesehen sind. Derartige Bürsten sind verhältnismäßig leistungsschwach und nicht als Schleifhandwerkzeug verwendbar.Vacuum cleaner accessories are known which with the exhaust air flow over actuated a drive fan rotating brushes included and especially for the processing of textile floor coverings are. Such brushes are relatively underperforming and cannot be used as a hand sanding tool.
Vorteile der ErfindungAdvantages of invention
Die vorliegende Erfindung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass eine kleine, leichte und kostengünstige Handwerkzeugmaschine geschaffen wurde, die allein durch Anschließen eines Staubsaugerabsaugschlauches an eine vorgesehene Kupplung bestimmungsgemäß betreibbar ist und bei der zugleich anfallender Schleifstaub mit hohem Wirkungsgrad absaugbar ist. Dadurch entfällt die Notwendigkeit, einen Elektromotor und eine Stromversorgung für die Handwerkzeugmaschine zur Verfügung zu stellen. Außerdem entfällt das sonst übliche laute Geräusch von Elektrohandwerkzeugmaschinen – bedingt durch die übliche Verwendung hochdrehender Elektromotoren.The present invention with the Features of claim 1 has the advantage that a small, light and inexpensive Handheld machine tool was created solely by connecting a vacuum cleaner suction hose can be operated as intended on a coupling provided and at at the same time, dust from grinding can be extracted with high efficiency is. This eliminates the need for an electric motor and a power supply for the hand machine tool to disposal to deliver. Moreover deleted the usual loud noise of electrical hand machine tools - due to the usual use of high-speed Electric motors.
Dadurch, dass im Inneren des Gehäuses ein drehbar gelagertes Turbolüfterrad angeordnet ist, das vom Saugluftstrom durchströmbar ist und mit dem Schleifteller koppelbar ist, ist eine einfach aufgebaute, leichte, geräuscharme und kostengünstige Handschleifmaschine mit Staubabsaugung geschaffen.The fact that a rotatable inside the housing mounted turbo fan wheel is arranged, which can be flowed through by the suction air flow and with the grinding plate can be coupled, is a simply constructed, lightweight, low-noise and inexpensive hand grinder created with dust extraction.
Dadurch, dass zwischen dem Turbolüftenad und dem Schleifteller ein Getriebe angeordnet ist, insbesondere ein Planetengetriebe, kann eine verhältnismäßig hohe Drehzahl des Turbolüfterrades bequem in eine, für Schleifmaschinen übliche geringere Drehzahl umgewandelt werden.The fact that between the turbo vent and a gear, in particular a Planetary gears can be a relatively high Speed of the turbo fan wheel convenient in one, for Grinders usual lower speed can be converted.
Dadurch, dass nicht verschließbare Öffnungen zum Einlass nachströmender Luft im Gehäuse der Handschleifmaschine vorgesehen sind, ist ein Abdrosseln bzw. Überlastung des Staubsaugers beim Schleifen ausgeschlossen.The fact that openings are not closable inflowing to the inlet Air in the housing of the Hand grinder are provided, throttling or overloading of the vacuum cleaner when grinding.
Dadurch, dass der Turbolüfter mit vertikaler Achse über ein Getriebe und von diesem weiter zum Schleifteller geführt ist, ist eine einfache und platzsparende, flache Bauweise der Handschleifmaschine möglich.The fact that the turbo fan with vertical axis over a gear and from there to the sanding plate, a simple and space-saving, flat design of the hand grinder is possible.
Dadurch, dass der Schleifteller exzentrisch angetrieben ist und mit einem Bremsring bis unter eine zulässige Höchstdrehzahl abbbremsbar ist, ist eine vorteilhaft handhabbare Exzenterschleifmaschine geschaffen.Because the sanding disc is eccentrically driven is and can be braked to below a permissible maximum speed with a brake ring, is an advantageously manageable eccentric grinding machine.
Zeichnung Nachstehend ist die Erfindung anhand eines Ausführungsbeispiels mit zugehöriger Zeichnung näher erläutert.Drawing The invention is based on of an embodiment with associated drawing explained in more detail.
