Werkzeugaggregat zum Entgraten von KunststoffwerkstückenTool unit for deburring plastic workpieces

Die Neuerung betrifft ein Werkzeugaggregat nach dem Oberbegriff des Anspruches 1.The innovation relates to a tool unit according to the preamble of claim 1.

Das saubere Entgraten von Werkstücken aus Kunststoff ist bisher zeit- und kostenaufwendig und wird entweder von Hand oder mit Hilfe von komplizierten Werkzeugsystemen durch Abtasten der Entgratungsstellen durchgeführt. Insbesondere an schwierig zugänglichen Stellen treten hierbei erhebliche Probleme auf.The clean deburring of plastic workpieces has so far been time-consuming and costly and is carried out either by hand or with the help of complicated tool systems by scanning the deburring points. Significant problems arise in this regard, particularly in hard-to-reach places.

Aufgabe der Neuerung ist es, das Entgraten von Werkstücken bzw. Gegenständen aus Kunststoff ohne Abtasten der Entgratungsstellen vorzunehmen und hierfür eine einfache, kostengünstige und zuverlässig arbeitende Vorrichtung anzugeben.The aim of the innovation is to deburr workpieces or objects made of plastic without scanning the deburring points and to provide a simple, cost-effective and reliable device for this purpose.

Gemäß der Neuerung wird dies bei einem Werkzeugaggregat mit den kennzeichnenden Merkmalen des Anspruches 1 erreicht. Weitere Ausgestaltungen der Neuerung sind Gegenstand der Unteransprüche.According to the innovation, this is achieved with a tool unit having the characterizing features of claim 1. Further embodiments of the innovation are the subject of the subclaims.

Das neuerungsgemäße Werkzeug ist auf einer Drehachse schwimmend gelagert und wird von einem Rotorkopf aufgenommen und geführt. Der Werkzeugträger ist in einem auf der Drehachse gelagerten Tragarm angeordnet, an dessen einem Ende Federstifte von zwei entgegengesetzten Seiten aus in Anlage stehen, so daß der Tragarm und damit das am entgegengesetzten Ende des Tragarmes angeordnete Entgratungswerkzeug in beiden Richtungen auslenken und das Werkzeug dem Verlauf der Entgratungskante des Werkstückes selbsttätig folgt. Das Andrücken des Entgratungsmessers an die zu entgratende Werkstückkante kann wahlweise über Zahnsegmente mit gegenläufigen Zahnrädern über motorischen Antrieb und/oder über Federkraft erfolgen.The new tool is mounted floating on a rotary axis and is held and guided by a rotor head. The tool carrier is arranged in a support arm mounted on the rotary axis, at one end of which spring pins are in contact from two opposite sides, so that the support arm and thus the deburring tool arranged at the opposite end of the support arm can be deflected in both directions and the tool automatically follows the course of the deburring edge of the workpiece. The deburring knife can be pressed onto the edge of the workpiece to be deburred using toothed segments with opposing gears, a motor drive and/or spring force.

Mit dem neuerungsgemäßen Werkzeug wird erreicht, daß ein Schwinden der Abmessungen des Werkstückes nach dem Entfernen aus der Form bis zu etwa 10 mm aufgefangen werden kann.The innovative tool makes it possible to compensate for a shrinkage of up to 10 mm in the dimensions of the workpiece after it has been removed from the mold.

Nachstehend wird die Neuerung in Verbindung mit der Zeichnung anhand eines Ausführungsbeispieles erläutert. Es zeigt:The innovation is explained below in conjunction with the drawing using an example of implementation. It shows:

Fig. 1 eine schematische Darstellung des neuerungsgemäßen Entgratungsaggregates in Aufsicht,Fig. 1 a schematic representation of the new deburring unit in top view,

Fig. 2 das Werkzeugaggregat nach Fig. 1 in detaillierterer Darstellung, und Fig. 3 eine Seitenschnittansicht der Darstellung nach Fig. 2 längs der Schnittlinie l-l.Fig. 2 shows the tool unit according to Fig. 1 in a more detailed representation, and Fig. 3 is a side sectional view of the representation according to Fig. 2 along the section line l-l.

Ein Roboterkopf 1 nimmt an einem Roboterflansch 2 über eine Mittelachse 3 efrren Werkzeugträger.4 auf, der über Verbindungsstellen 5, z.B. Schraubverbindungen am Flansch 2 befestigt ist. Der Werkzeugträger 4 besteht aus einem Tragarm 6 mit Drehachse 7 und Achsführungen 8, 9, einem Messerträger 10 mit Entgratungsmesser 11, sowie Federanordnungen 12, 13, die über Federstifte 14, 15 beidseitig mit dem Tragarm 6 in Eingriff stehen und durch Federwirkung den Tragarm in die Ausgangsposition zurückführen. Die Arbeitsrichtung bzw. Ziehrichtung des Werkzeuges 11 ist mit 16, das Werkstück mit 17 bezeichnet.A robot head 1 receives a tool carrier 4 on a robot flange 2 via a central axis 3, which is attached to the flange 2 via connection points 5, e.g. screw connections. The tool carrier 4 consists of a support arm 6 with a rotation axis 7 and axis guides 8, 9, a knife carrier 10 with a deburring knife 11, and spring arrangements 12, 13, which engage with the support arm 6 on both sides via spring pins 14, 15 and return the support arm to the starting position by spring action. The working direction or pulling direction of the tool 11 is designated 16, the workpiece 17.
