Zentrischgreifer bieten wir standardmäßig als Kleinteile-, Universal- und Dichte-Greifer mit drei Fingern für das sichere und präzise Außen- und Innengreifen von Werkstücken mit Gewichten zwischen wenigen Gramm und mehr als 100 Kilogramm an. Ihr Einsatzspektrum reicht vom Reinraum bis zu explosionsgefährdeten Arbeitsbereichen, von normalen Umgebungsbedingungen bis zu Hochtemperatur-Anwendungen. Die Möglichkeit, die Greifer z.B. mit Sensorik, produktespezifischen Greiffingern, Zwischenbacken zu kombinieren, sorgt für mehr Produktivität. Darüber hinaus stehen konstruktive Finessen, wie die Vielzahn-Gleitführung in Verbindung mit Fertigungstechnologien -state of the art - für robuste Zuverlässigkeit und damit letztlich für Langlebigkeit und Investitionssicherheit.
is calculated for force-fit clamping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. In the case of form-fit gripping, significatnly higher permissible workpiece weights are possible.
Example: - For the catalog-specified workpiece weight of 5 kg Gripping force of the gripper 1,000 N Coefficient of friction μ 0.1; safety factor 2; g 9.81
For supported control systems, we provide specific software resources (e.g., function blocks or parameter sets). This simplifies software commissioning and integration. Is your target system not listed? Please contact us!
In the event of energy or pressure loss, seven variants secure the gripping force and/or the current position:
AS (spring closing)/IS (spring opening): A spring holds the gripper closed or open with minimum force. S (spring closing/opening): Depending on the design of the top jaws, the spring acts as a closing or opening mechanism. ASC (certified spring closing)/ISC (certified spring opening): The certified GripGuard gripping force maintenance ensures at least 80% gripping force in the closing or opening direction in the event of a pressure drop. M (permanent magnetic brake): Maintains the gripping force in the closing and opening direction. KP (position clamping): Fixes the current position in the closing and opening direction – via a brake or a pneumatic clamping element.
The ambient temperature describes the temperature of the air or the direct operating environment in which a gripper is operated (and not the workpiece temperature, as this is normally significantly higher than the ambient temperature). We also offer special solutions for ambient temperatures above 130 °C. We would be happy to review your use case based on your specific process data.
Despite the high moment load of the base jaws, this sealed 3-finger centric gripper meets the requirements of IP67 and does not permit the ingress of any substances from the working environment into the interior of the component.
