Die Erfindung bezieht sich auf eine Maschine zum Abfräsen der Lauffläche eines Fahrzeugluftreifens zur Runderneuerung mittels eines an dem auf Felgenscheiben verspannten, aufgeblasenen Reifen angreifenden, durch einen Antriebsmotor angetriebenen Fräswerkzeuges, das zusammen mit dem Antriebsmotor an einer am Maschinengestell schwenkbar gelagerten Kniegelenkschvvinge mit senkrechten Gelenkachsen angeordnet ist, mit einer zugeordneten Schablone zur Führung des Fräs Werkzeuges.The invention relates to a machine for milling the tread of a pneumatic vehicle tire for retreading by means of an inflated tire that is clamped on the rim disks, by a drive motor driven milling tool, which together with the drive motor on a knee-joint swing with vertical joint axes, which is pivotably mounted on the machine frame is arranged, with an associated template for guiding the milling tool.
Bei solchen Maschinen ist es bekannt, den zu bearbeitenden Reifen in senkrechter Ebene zwischen Felgenscheiben von zwei koaxialen, horizontalen Wellen zu verspannen und mit Druckluft aufzublasen, die durch eine der Wellen zugeführt werden kann. Ferner ist es bekannt, den Reifen mit einer an seinem Umfang anliegenden, schwenkbar gelagerten Reibrolle in Drehung zu versetzen. Schließlich ist es bekannt, die Lauffläche des Reifens mit einem Fräswerkzeug abzufräsen, das zusammen mit seinem Antriebsmotor an einer am Maschinengestell schwenkbar gelagerten Kniegelenkschwinge mit senkrechten Gelenkachsen angeordnet ist, und das Fräswerkzeug an einer dem Reifenprofil angepaßten Schablone zu führen.In such machines, it is known, the tire to be processed in a vertical plane between To clamp the rim disks of two coaxial, horizontal shafts and to inflate them with compressed air, which can be fed through one of the shafts. It is also known to the tire with one on his Circumferentially adjacent, pivotably mounted friction roller to rotate. After all, it is known Mill the tread of the tire with a milling tool that works together with its drive motor on a swiveling knee joint rocker with vertical joint axes is arranged, and to guide the milling tool on a template adapted to the tire profile.
Der Erfindung liegt die Aufgabe zugrunde, eine mit diesen bekannten Merkmalen versehene Reifenfräsmaschine so auszubilden, daß das Fräswerkzeug zusammen mit seinem Antriebsmotor selbsttätig längs der Schablone an der Lauffläche des hierbei umlaufenden Reifens hin- und herbewegt werden kann, bis die abgefräste Lauffläche das vorgesehene Endprofil für die Runderneuerung aufweist, wobei der Antrieb für die hin- und hergehende Bewegung des Fräswerkzeuges nur einen geringen Kraftverbrauch aufweisen und so ausgebildet sein' soll, daß sich das Fräswerkzeug mit diesem Antrieb leicht entkuppeln und zum Freilegen des Luftstreifens an beiden Seiten sowie zur guten Zugänglichkeit seiner Aufspannmittel aus dem Arbeitsbereich fortschwenken läßt.The invention is based on the object of a tire milling machine provided with these known features to train so that the milling tool automatically along with its drive motor the template can be moved back and forth on the tread of the surrounding tire, until the milled tread has the intended end profile for retreading, the Drive for the back and forth movement of the milling tool only consumes little power have and be designed so that the milling tool can easily decouple with this drive and for exposing the air strip on both sides and for easy access to its clamping means can swing away from the work area.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Welle des Antriebsmotors für das mit
senkrechter Achse darüber angeordnete Fräswerkzeug einen nach unten ragenden, mit einer daran
drehbar gelagerten Stützrolle versehenen Wellenschaft zur Führung an der Schablone aufweist, der
von einer auf dem Schablonenhalter gelagerten, angetriebenen Gabel zur hin- und hergehenden Bewegung
des Fräswerkzeuges umfaßt ist. Bei dieser Ausbildung des Antriebes für die hin- und hergehende
Bewegung des Fräswerkzeuges an der Lauffläche des umlaufenden Reifens kann man das Fräswerkzeug
zusammen mit seinem Antriebsmotor jeder-Maschine zum Abfräsen der Lauffläche eines
Fahrzeugluftreifens zur RunderneuerungThis object is achieved according to the invention in that the shaft of the drive motor for the milling tool arranged with a vertical axis above has a downwardly projecting shaft shaft provided with a supporting roller rotatably mounted on it for guidance on the template, which is driven by a fork mounted on the template holder is included for reciprocating movement of the milling tool. With this design of the drive for the reciprocating movement of the milling tool on the tread of the rotating tire, the milling tool can be used together with its drive motor of each machine for milling the tread of a

F i g. 2 das Arbeitsschema der Maschine im Grundriß.F i g. 2 the working diagram of the machine in plan.
Das Maschinengestell weist einen Grundrahmen 1, zwei Säulen 2 und 3 und eine obere Traverse 4 auf.
An der Säule 3 ist ein Lenkerrahmen 6 um eine lotrechte Achse schwenkbar gelagert. Am äußeren Ende
des Lenkerrahmens ist ein zweiter Lenkerrahmen 5 ebenfalls um eine lotrechte Achse schwenkbar, der
an seinem freien Ende einen Fräskopf trägt. Der Fräskopf besteht aus einem als Elektromotor ausgebildeten
Antriebsmotor 7 und einem am oberen Ende des lotrechten Wellenschafts 8 angeordneten Fräswerkzeug
9, das teilweise von einem Schutzgehäuse umgeben ist.
Die Lenkerrahmen 5 und 6 werden von einem pneumatisch betätigten Kolben hin- und herbewegt,
der in einem in der Nähe des Grundrahmens 1 angeordneten Zylinder gelagert ist. Der Antrieb der
Lenkerrahmen kann aber auch auf andere Weise erfolgen. The machine frame has a base frame 1, two columns 2 and 3 and an upper cross member 4. A link frame 6 is mounted on the column 3 so as to be pivotable about a vertical axis. At the outer end of the handlebar frame, a second handlebar frame 5 is also pivotable about a vertical axis, which carries a milling head at its free end. The milling head consists of a drive motor 7 designed as an electric motor and a milling tool 9 which is arranged at the upper end of the vertical shaft shaft 8 and which is partially surrounded by a protective housing.
The handlebar frames 5 and 6 are moved back and forth by a pneumatically operated piston which is mounted in a cylinder arranged in the vicinity of the base frame 1. The link frame can also be driven in other ways.
Ebenfalls in der Nähe des Grundrahmens 1 befindet sich ein Schablonenhalter 12, in den eine Schablone 13 austauschbar eingesetzt ist. Die Stirn-Also in the vicinity of the base frame 1 is a template holder 12 into which one Template 13 is used interchangeably. Forehead-
