Der Erfindung liegt die Aufgabe zugrunde, das Schuhschleifen von Werkstücken, beispielsweise Wälzlagerringen, gegenüber dem genannten Stand der Technik rationeller zu gestalten, wobei unter den Bedingungen der Serienfertigung eine hohe Fertigungspräzision erreichbar sein soll.The invention is based on the object of making the shoe grinding of workpieces, for example roller bearing rings, more efficient than the stated prior art, with a high level of manufacturing precision being achievable under the conditions of series production.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Vorrichtung zum Schuhschleifen gemäß Anspruch 1. Ebenso wird die Aufgabe gelöst durch ein Verfahren zur Bearbeitung eines Werkstücks nach dem Anspruch 9. Im Folgenden im Zusammenhang mit dem Bearbeitungsverfahren erläuterte Ausgestaltungen und Vorteile gelten sinngemäß auch für die Schuhschleifvorrichtung und umgekehrt.This object is achieved according to the invention by a device for shoe grinding according to claim 1. The object is also achieved by a method for machining a workpiece according to claim 9. The embodiments and advantages explained below in connection with the machining method also apply mutatis mutandis to the shoe grinding device and vice versa .
Die Schuhschleifvorrichtung umfasst mindestens eine zur Aufnahme eines Schuhs vorgesehene Schuhaufnahme, welche an einem Arm befestigt ist, sowie eine zur Verstellung des Arms in dessen Längsrichtung ausgebildete Verstelleinheit, welche einen Stellmotor und ein Stellgetriebe umfasst, wobei das Stellgetriebe ein Rotativ-Linear-Getriebe umfasst. Bei dem Schuh handelt es sich beispielsweise um einen Prismenschuh oder einen Formschuh.The shoe grinding device comprises at least one shoe holder provided for receiving a shoe, which is attached to an arm, as well as an adjusting unit designed to adjust the arm in its longitudinal direction, which comprises a servomotor and an actuating gear, the actuating gear comprising a rotary-linear gear. The shoe is, for example, a prism shoe or a shaped shoe.
Durch den motorischen Antrieb der Schuhaufnahme und damit auch des zur Abstützung des zu schleifenden Werkstücks geeigneten Schuhs eignet sich die Schuhschleifvorrichtung besonders zur Einbindung in hochautomatisierte Fertigungsanlagen, wobei zugleich eine hohe Flexibilität gegeben ist. Im Vergleich zu herkömmlichen Schleifvorrichtungen lässt sich die Schuhschleifvorrichtung bei einem Wechsel der zu bearbeitenden Werkstücktypen mit äußerst geringem Aufwand umrüsten. Das Rotativ-Linear-Getriebe der Verstelleinheit begünstigt zudem eine präzise, bei Bedarf exakt wiederholbare Positionierung des Schuhs.As a result of the motorized drive of the shoe holder and thus also of the shoe that is suitable for supporting the workpiece to be ground, the shoe grinding device is particularly suitable for integration into highly automated production systems, with a high degree of flexibility at the same time. Compared to conventional grinding devices, the shoe grinding device can be retooled with extremely little effort when the workpiece types to be processed are changed. The rotary-linear gear of the adjustment unit also promotes precise positioning of the shoe, which can be repeated if necessary.
Als Rotativ-Linear-Getriebe der Verstelleinheit ist ein einfaches Bewegungsgewinde, insbesondere mit Trapezgewinde, geeignet. Ebenso sind sonstige Typen von Rotativ-Linear-Getrieben, beispielsweise Planetenwälzgetriebe oder Kugelgewindetriebe, in der Verstelleinheit verwendbar. Zum Stand der Technik wird beispielhaft auf die Dokumente
In bevorzugter Ausgestaltung umfasst das Rotativ-Linear-Getriebe eine federbelastete Sperrvorrichtung. Die Sperrvorrichtung weist vorzugsweise mindestens ein im Querschnitt keilförmiges Klemmelement auf, wobei auch insgesamt ringförmige Klemmelemente zum Einsatz kommen können.In a preferred embodiment, the rotary-linear gear includes a spring-loaded locking device. The locking device preferably has at least one clamping element which is wedge-shaped in cross section, it also being possible to use overall annular clamping elements.
Unabhängig von der geometrischen Gestaltung des Klemmelements umfasst das Rotativ-Linear-Getriebe vorzugsweise eine zum Lösen der Sperrvorrichtung vorgesehene Entsperrvorrichtung, welche pneumatisch arbeitet. Sofern die Entsperrvorrichtung zu diesem Zweck mehrere Pneumatikmotoren aufweist, sind diese vorzugsweise in einem ein Abtriebselement des Rotativ-Linear-Getriebes umgebenden Ringraum angeordnet ist, wobei jeder Pneumatikaktor eine zur Mittelachse des Abtriebselementes parallele Längsachse aufweist. Das Abtriebselement kann mit dem Arm der Verstelleinheit verbunden oder identisch sein.Regardless of the geometrical design of the clamping element, the rotary-linear gear preferably comprises an unlocking device which is provided for releasing the locking device and which operates pneumatically. If the unlocking device has several pneumatic motors for this purpose, these are preferably arranged in an annular space surrounding an output element of the rotary-linear transmission, each pneumatic actuator having a longitudinal axis parallel to the central axis of the output element. The output element can be connected to the arm of the adjustment unit or it can be identical.
Gemäß einer vorteilhaften Weiterbildung ist dem Rotativ-Linear-Getriebe ein Umschlingungsgetriebe, insbesondere in Form eines Riementriebs, vorgeschaltet. Zum Antrieb des Umschlingungsgetriebes ist beispielsweise ein als Schrittmotor gestalteter Elektromotor geeignet. Der Elektromotor entspricht in bevorzugter Ausgestaltung mindestens der Schutzklasse IP65.According to an advantageous development, the rotary / linear transmission is preceded by a belt transmission, in particular in the form of a belt drive. For example, an electric motor designed as a stepping motor is suitable for driving the belt drive. In a preferred embodiment, the electric motor corresponds at least to protection class IP65.
Eine Schleifanlage, welche sich zur Durchführung des erfindungsgemäßen Verfahrens eignet, kann entweder eine einzige Vorrichtung gemäß Anspruch 1 oder mehrere derartige Vorrichtungen umfassen. Die Verstelleinheit oder Verstelleinheiten werden in bevorzugter Verfahrensführung mit Sperrluft beaufschlagt, womit insbesondere ein Eindringen von Kühlmittelflüssigkeit verhindert wird.A grinding system which is suitable for carrying out the method according to the invention can either have a single device according to FIG Claim 1 or more such devices comprise. The adjustment unit or adjustment units are acted upon with sealing air in a preferred procedure, which in particular prevents the penetration of coolant liquid.
