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, wobei an dessen dem Schwunggewicht zugekehrten Ende ein Werkzeugträger 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 schwingber 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, with an end facing the flywheel Tool carrier is 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 in a vibrating manner on the housing and thus transmits an essentially circular oscillating oscillating movement to an object to be treated.

Bei einem bekannten Gerät der genannten Art (EP-A-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-0 012 129), the tool and the tool holder receiving it are connected inelastically via a fixed connection to the motor which runs out of balance due to a flywheel weight, this unit being mounted so that it can swing in the housing so 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 dem Antriebsmotor ab einer vorher bestimmberen Andruckbelastung ermöglicht, in der Qelben Weise - nämlich in einer kreisförmig pendetndt.n Schwingbewegung - weiterzuschwingen. Bis zum Inkrafttreten dieser, durch die Auswahl der Elastizität der zusätzlichen elastischen Halterung bestimmberen 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. Thus, another vibration system is formed within the existing oscillating system, which enables the drive motor from a previously bestimmberen Andruckbelastung in the Q same way - namely in a circular oscillatory movement pendetndt.n - weiterzuschwingen. Until this effect, which is 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.

Weiterbildungen der Erfindung sind in den Unteransprüchen dargestellt. Diese betreffen insbesondere bevorzugte Ausbildungen und Anordnungen der zusätzlich zwischen Motor und Werkzeugträger bzw. Werkzeug angeordneten, als elastische Halterung bezeichneten elastischen Verbindung.Further developments of the invention are presented in the subclaims. These relate in particular to preferred configurations and arrangements of the elastic connection, which is additionally arranged between the motor and the tool carrier or tool and is referred to as an elastic holder.

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-1 in Fig. 1.
The invention is explained in more detail using an exemplary embodiment: It shows
  • Fig. 1 shows a device according to the invention in longitudinal section and
  • FIG. 2 shows a cross section along lines I-1 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 dem 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 verteilte und in einer zur Motorlängsachse senkrechten Ebene angeordnete 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 tapers 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 - represented by the lines of symmetry 7 are 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 arranged in a plane perpendicular to the longitudinal axis of the motor, in such a way that between the lower housing edge and the A gap of about 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 1 ist. Die höhere Zahl der für die zusätzliche HεIterung 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 pins 11 'are also arranged in the plane perpendicular to the longitudinal axis of the motor, evenly distributed around a central circle which is somewhat larger than the outer diameter of the motor 1. The higher number of swing pins 11 'used for the additional hardening 11 results in a higher stiffness compared to those of the swing 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 attached to the engine 1 on the other side. This is made possible by means of a double-arm bracket 13 and a centering disk 14 arranged on the side of the flywheel weight 2, which clamp the motor 1 after the nuts 10 have been tightened.

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 17 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 17 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 is made of thin-walled pressed plastic 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 by means of 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.
