Description

Die Erfindung betrifft ein Gerät zur Oberflächenbehandlung, insbesondere zum Reinigen, Polieren und Abschleifen, bestehend aus einem Gehäuse, gegebenenfalls mit daran angeordneter Handhabe, einem vom Gehäuse zumindest teilweise umschlossenen, durch ein Schwunggewicht unwuchtig laufenden elektrischen Motor, dessen dem Schwunggewicht zugekehres Ende über einen Werkzeugträger fest mit einem Werkzeug verbunden ist, und wobei die aus Motor und Werkzeugträger bestehende Einheit an dem dem Schwunggewicht gegenüberliegenden Motorende durch eine im Gehäuse bzw. an der Handhabe angeordnete schwenkbare Halterung pendelartig und im Bereich des Schwunggewichtes durch eine zwischen Werkzeugträger und Gehäuse angeordnete, aus Schwingbolzen od. dgl. bestehende Schwinglagerung schwingbar am Gehäuse gehalten ist und damit eine im wesentlichen kreisförmig pendelnde Schwingbewegung auf einen zu behandelnden Gegenstand überträgt.The invention relates to a device for surface treatment, in particular for cleaning, polishing and grinding, consisting of a housing, optionally with a handle arranged thereon, an electric motor at least partially enclosed by the housing and running unbalanced by a flywheel, the end of which is towards the flywheel weight via a tool holder is firmly connected to a tool, and the unit consisting of motor and tool carrier is pendulum-like at the end of the motor opposite the flywheel weight by means of a pivotable holder arranged in the housing or on the handle, and in the area of the flywheel weight by a pivot pin arranged between tool carrier and housing or the like. Existing oscillating bearing is held on the housing so as to be oscillatable and thus transmits an essentially circular oscillating oscillating movement to an object to be treated.

Bei einem bekannten Gerät der genannten Art (EP - A1 - 0 012 129) ist das Werkzeug und der dieses aufnehmende Werkzeugträger über eine feste Verbindung mit dem durch ein Schwunggewicht unwuchtig laufenden Motor unelastisch verbunden, wobei diese Einheit im Gehäuse schwingbar so gelagert ist, daß damit eine kreisförmig pendelnde Schwingbewegung auf einen zu behandelnden Gegenstand übertragbar ist. Nachdem dabei die Motorwelle nicht unmittelbar auf den Werkzeugträger einwirkt und Exzenter od. dgl. zur Schwingungsübertragung nicht benötigt werden, ist eine erheblich geringere Antriebsleistung erforderlich.In a known device of the type mentioned (EP-A 1 - 0 012 129), the tool and the tool holder receiving it are connected inelastic via a fixed connection to the motor which runs unbalanced due to a flywheel weight, this unit being mounted so that it can vibrate in the housing, that a circular oscillating oscillating movement can be transferred to an object to be treated. Since the motor shaft does not act directly on the tool carrier and eccentrics or the like are not required for the transmission of vibrations, a considerably lower drive power is required.

Das wesentlich geringere Gewicht des Gerätes veranlaßt aber andererseits in nachteiliger Weise die das Gerät bedienende Person oftmals zu einem übermäßig hohen Arbeitsdruck, in der Meinung, damit das Behandlungsergebnis verbessern zu können. Wenngleich dadurch eine Überlastung des Motors mangels einer mechanischen Verbindung zwischen der Motorwelle und dem Werkzeugträger nicht möglich ist, können doch länger andauernde stärkere Andruckbelastungen zu einem vorzeitigen Verschleiß der Motorlagerung führen, da die Schwingungen dann über diese an das Gehäuse abgeleitet werden.On the other hand, the much lower weight of the device disadvantageously causes the person operating the device to an excessively high working pressure, in the opinion that this can improve the treatment result. Although this does not result in an overload of the motor due to the lack of a mechanical connection between the motor shaft and the tool holder, longer, longer pressure loads can lead to premature wear of the motor mounting, since the vibrations are then diverted to the housing.

Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil bei einem Gerät der eingangs erwähnten Art zu beseitigen.The invention has for its object to eliminate this disadvantage in a device of the type mentioned.

Erfindungsgemäß wird dies dadurch erreicht, daß Motor und Werkzeugträger durch eine zusätzliche, gegenüber der elastischen Schwinglagerung steifer wirkende elastische Halterung miteinander verbunden sind. Damit wird innerhalb des bestehenden Schwingsystems ein weiteres Schwingsystem gebildet, welches den Antriebsmotor ab einer vorher bestimmbaren Andruckbelastung ermöglicht, in der selben Weise - nämlich in einer kreisförmig pendelnden Schwingbewegung - weiterzuschwingen. Bis zum Inkrafttreten dieser, durch die Auswahl der Elastizität der zusätzlichen elastischen Halterung bestimmbaren Wirkung, ist die Wirkungsweise des Gerätes mit oder ohne der zusätzlichen elastischen Halterung dieselbe.According to the invention, this is achieved in that the motor and tool carrier are connected to one another by an additional elastic holder which acts more rigidly with respect to the elastic oscillating bearing. A further oscillation system is thus formed within the existing oscillation system, which enables the drive motor to continue oscillating in the same way - namely in a circular oscillating oscillation movement - from a previously determinable pressure load. Until this effect, which can be determined by the selection of the elasticity of the additional elastic holder, comes into effect, the mode of operation of the device with or without the additional elastic holder is the same.

In Weiterbildung der Erfindung kann dabei vorgesehen sein, daß die zusätzliche elastische Halterung aus einem Schwingelement, vorzugsweise aus mehreren an sich bekannten Schwingbolzen besteht, da durch solche die gewünschte elastische Wirkung einfacher zu erreichen ist. Nachdem diese Schwingbolzen üblicherweise eingeformte Muttern oder Gewindestifte aufweisen, ist auch eine Verbindung zwischen Motor und Werkzeugträger leichter durchführbar.In a further development of the invention it can be provided that the additional elastic holder consists of an oscillating element, preferably of a plurality of oscillating bolts known per se, since the desired elastic effect can be achieved more easily by such. Since these rocking bolts usually have molded nuts or grub screws, a connection between the motor and the tool holder is also easier to implement.

Besondere Vorteile können gemäß einer anderen Weiterbildung der Erfindung dadurch erzielt werden, wenn die Schwingbolzen der zusätzlichen elastischenHalterung und jene für die Schwinglagerung gleich ausgebildet und in der zur Motorlängsachse senkrechten Ebene gleichmäßig verteilt angeordnet sind, wobei die Schwingbolzen für die zusätzliche elastische Halterung einen höheren Härtegrad aufweisen und/oder in größerer Zahl angeordnet sind. Dies bringt nicht nur eine Senkung der hohen Werkzeugkosten, sondern auch eine wesentliche Vereinfachung der Konstruktion des Gerätes mit sich.According to another development of the invention, particular advantages can be achieved if the oscillating bolts of the additional elastic holder and those for the oscillating bearing are of identical design and are evenly distributed in the plane perpendicular to the longitudinal axis of the motor, the oscillating bolts having a higher degree of hardness for the additional elastic holder and / or are arranged in larger numbers. This not only reduces the high tool costs, but also significantly simplifies the design of the device.

Gemäß einer bevorzugten Ausführungsform der Erfindung werden erfindungsgemäße Vorteile auch dadurch erreicht, wenn der Motor über einen diesen umschließenden, am Ende als Gelenkkugel ausgebildeten Bügel und einer am antriebsseitigen Motorende angeordneten Zentrierscheibe mit den Schwingbolzen der zusätzlichen elastischen Halterung verbunden ist, wobei die vzw. Gelenkkugel in einer im Gehäuseende bzw. in der Handhabe angeordneten, diese zumindest über die Hälfte umschließende, einstückig gefertigte Lagerschale gelagert ist, deren offene Seite mehrere bis über die Schalenmitte reichende Radialschlitze aufweist. Damit werden Eigenschwingungen vennieden, welche für die Wirkungsweise des erfindungsgemäßen Gerätes besonders nachteilig sind. Nachdem dabei die weiteren Verbindungen ohne Schrauben hergestellt sind, können auch durch gelockerte Schraubverbindungen hervorgerufene Eigenschwingungen im Schwingsystem nicht mehr auftreten.According to a preferred embodiment of the invention, advantages according to the invention are also achieved if the motor is connected to the oscillating bolts of the additional elastic holder via a bracket surrounding the latter, which is designed as a joint ball at the end and a centering disk arranged on the drive-side motor end, the vzw. Articulated ball is mounted in a one-piece bearing shell which is arranged in the housing end or in the handle and surrounds this at least half, the open side of which has a plurality of radial slots extending beyond the middle of the shell. So that natural vibrations vennieden, which are particularly disadvantageous for the operation of the device according to the invention. After the other connections have been made without screws, natural vibrations caused by loosened screw connections can no longer occur in the vibration system.

Die Erfindung wird anhand eines Ausführungsbeispieles näher erläutert:

  • Es zeigen Fig. 1 ein Gerät nach der Erfindung im Längsschnitt und Fig. 2 einen Querschnitt nach den Linien I-I in Fig. 1.
The invention is explained in more detail using an exemplary embodiment:
  • 1 shows a device according to the invention in longitudinal section and FIG. 2 shows a cross section along lines II in FIG. 1.

In Fig. 1 ist der Elektromotor 1 durch das Schwunggewicht 2 unwuchtig angetrieben und in einem am Ende des Gehäuses 4 angeordneten Schwenklager 5 schwenkbar gelagert, sodaß dieser zusammen mit dem an ihm befestigten Werkzeugträger 3 eine kreisförmig pendelnde Schwingbewegung auf einen zu behandelnden Gegenstand überträgt.In Fig. 1, the electric motor 1 is driven unbalanced by the swing weight 2 and pivotally mounted in a pivot bearing 5 arranged at the end of the housing 4, so that this, together with the tool carrier 3 attached to it, transmits a circular oscillating swinging motion to an object to be treated.

Das Gehäuse 4 besteht aus drei Teilen, nämlich den tragenden Gehäuseteil 4, das zum Werkzeugträger 3 hin konisch verläuft und den beiden schalenförmig ausgebildeten Teilen 4', 4", die zusammen die wulstförmige Handhabe bilden. Die drei Gehäuseteile sind mittels mehrerer Schrauben - dargestellt durch die Symmetrielinien 7 - miteinander verbunden. Das Gehäuseteil 4 endet mit einem ringförmigen Ansatz. Der schalenförmig ausgebildete Werkzeugträger 3 ist durch drei am äußeren Gehäuserand gleichmäßig verteilten und in der zur Motorlängsachse senkrechten Ebene angeordneten Schwingbolzen 8' so gelagert, daß zwischen dem unteren Gehäuserand und der Oberkante des Werkzeugträgers 3 ein Spalt von etwa 3 bis 4 mm entsteht. Die beiderseits mit Gewindestiften 9 ausgebildeten Schwingbolzen 8' sind dabei an einem Ende am Werkzeugträger 3 eingeschraubt, am anderen Ende mittels der Schlitzmuttern 10 mit dem Gehäuse 4 verbunden.The housing 4 consists of three parts, namely the load-bearing housing part 4, which runs conically towards the tool carrier 3 and the two shell-shaped parts 4 ', 4 ", which together form the bead-shaped handle. The three housing parts are represented by means of several screws the lines of symmetry 7 - connected to one another The housing part 4 ends with an annular shoulder The shell-shaped tool carrier 3 is supported by three oscillating bolts 8 'which are evenly distributed on the outer housing edge and are arranged in the plane perpendicular to the longitudinal axis of the motor so that between the lower housing edge and the A gap of approximately 3 to 4 mm is created at the upper edge of the tool carrier 3. The swing bolts 8 ′ formed on both sides with threaded pins 9 are screwed onto the tool carrier 3 at one end and connected to the housing 4 at the other end by means of the slotted nuts 10.

Der Motor 1 und der Werkzeugträger 3 sind durch eine zusätzliche, aus vier Schwingbolzen 11' bestehende elastische Halterung 11 miteinander verbunden. Die Schwingbolzen 11' sind ebenfalls in der zur Motorlängsachse senkrechten Ebene gleichmäßig verteilt um einen Mittelkreis angeordnet, der etwas größer als der Außendurchmesser des Motors list. Die höhere Zahl der für die zusätzliche Halterung 11 verwendeten Schwingbolzen 11' bewirkt dabei eine höhere Steifheit gegenüber jenen der Schwinglagerung 8. Dieselben können gegebenenfalls auch einen höheren Härtegrad aufweisen. Auch die Schwingbolzen 11' weisen beiderseits Gewindestifte auf und sind an der einen Seite am Werkzeugträger 3 eingeschraubt und an der anderen Seite am Motor 1 befestigt. Dies wird mittels eines doppelarmigen Bügels 13 und einer an der Seite des Schwunggewichtes 2 angeordneten Zentrierscheibe 14 ermöglicht, welche den Motor 1 nach Festziehen der Muttern 10 festklemmen.The motor 1 and the tool carrier 3 are connected to one another by an additional elastic holder 11 consisting of four swing bolts 11 '. The swing bolts 11 'are also arranged in the plane perpendicular to the longitudinal axis of the motor, evenly distributed around a center circle which is somewhat larger than the outside diameter of the motor. The higher number of rocking pins 11 'used for the additional bracket 11 results in a higher stiffness compared to those of the rocking bearing 8. The same may also have a higher degree of hardness. The swing bolts 11 'also have setscrews on both sides and are screwed onto the tool carrier 3 on one side and fastened to the motor 1 on the other side. This is done by means of a double-armed bracket 13 and a Zen arranged on the side of the swing weight 2 Trierscheibe 14 enables which clamp the motor 1 after tightening the nuts 10.

Der aus einem Kunststoffpreßteil bestehende doppelarmige Bügel 13 endet mit einem Kugelkopf 15, der seinerseits in der aus einem Stück bestehenden Lagerschale 16 haltbar und schwenkbar gelagert ist. Zu diesem Zweck umfaßt die Lagerschale 16 den Kugelkopf 15 mehr als zur Hälfte und ist über diesen aufgepreßt. Dies wird durch mehrere am offenen Ende der Lagerschale 16 angeordnete, bis etwa zur Schalenmitte reichende Radialschlitze 16' ermöglicht. Die in einem ringförmigen Ansatz 19 im Gehäuseteil 4" angeordnete Lagerschale 16 ist mittels der Schraube 18 gehalten.The double-armed bracket 13, which is made of a pressed plastic part, ends with a ball head 15, which in turn is mounted in the one-piece bearing shell 16 so that it can be held and pivoted. For this purpose, the bearing shell 16 comprises the ball head 15 more than half and is pressed over this. This is made possible by a plurality of radial slots 16 ′ arranged at the open end of the bearing shell 16 and extending approximately to the middle of the shell. The bearing shell 16 arranged in an annular extension 19 in the housing part 4 ″ is held by means of the screw 18.

Der Werkzeugträger besteht ebenso wie alle übrigen Gehäuseteile aus dünnwandigen Kunststoffpreßteilen. Dieser ist schalenförmig ausgebildet und kann an seinem Umfang Befestigungsmittel, z. B. einen Ring 24 für ein Reinigungstuch 23 aufnehmen. Andere mit unterschiedlichen Werkstoffen ausgebildete Werkzeuge können z. B. durch Eigenspannung an dieser Fläche gehalten sein. Die Unterseite des Werkzeugträgers 3 kann auch mit einem selbsthaftenden Belag ausgebildet sein, der verschiedene Werkzeuge, wie Felle, Schleifvliese oder Schleifblätter, selbsthaftend aufnimmt.Like all other housing parts, the tool carrier consists of thin-walled plastic pressed parts. This is bowl-shaped and can fasteners on its circumference, for. B. record a ring 24 for a cleaning cloth 23. Other tools designed with different materials can e.g. B. be held by internal stress on this surface. The underside of the tool carrier 3 can also be formed with a self-adhesive covering which holds various tools, such as skins, non-woven abrasives or sanding sheets, in a self-adhesive manner.

Am Gerät ist weiters ein Schalter 20 zum Ein- und Ausschalten des Motors 1 angeordnet, wobei das Stromzufuhrkabel 22 über eine Gummitülle 21 durch das Gehäuseteil 4' geführt ist.Furthermore, a switch 20 for switching the motor 1 on and off is arranged on the device, the power supply cable 22 being guided through the housing part 4 'via a rubber grommet 21.

Fig. 2 verdeutlicht die Lage der Schwingbolzen 8' bzw. 11' im Werkzeugträger 3.2 illustrates the position of the rocking pins 8 'and 11' in the tool carrier 3.

Die zusätzliche elastische Halterung 11 kann auch aus anderen Schwingungselementen bestehen. So ist es beispielsweise durchaus möglich, diese aus einem Stück, z. B. als elastische Manschette oder als elastischen Ring auszubilden. Ebenso haben andere Ausbildungen der Schwinglagerung 8 keinen wesentlichen Einfluß auf die Wirkungsweise des Gerätes.The additional elastic bracket 11 can also consist of other vibration elements. For example, it is quite possible to make them from one piece, e.g. B. as an elastic sleeve or as an elastic ring. Likewise, other designs of the vibration bearing 8 have no significant influence on the operation of the device.

Das erfindungsgemäße Gerät kann vom Stromnetz direkt bzw. über einen Netztrafo oder auch durch Akkubatterien betrieben werden. Durch Anbringen eines Stiels kann dieses auch als Bodengerät verwendet werden.The device according to the invention can be operated directly from the mains or via a mains transformer or also by rechargeable batteries. By attaching a handle, this can also be used as a floor device.

Es ist auch im Rahmen der Erfindung gelegen, ein Gerät der erfindungsgemäßen Art als Massagegerät auszubilden.It is also within the scope of the invention to design a device of the type according to the invention as a massage device.
