RotoClamp from HEMA is a pneumatic clamping system that, with its two directions of action, enables a wide range of applications. Specifically designed for rotary position clamping, it is available in internal and external clamping versions and is compatible with all common industry shaft sizes.
Individual adaptations
HEMA's customized adaptations enable the integration of RotoClamp clamping systems into any production machine with rotating guides or drives if the standard does not fit. After proper testing, customized mounting, or connection hole patterns, as well as housing shape modifications, are possible if the specific requirements of a machine assembly space require them. HEMA also implements alternative positioning of the pneumatic connection and customized series with clamping diameters different from standard products.
The functional principle of the RotoClamp remains unchanged despite all possible adaptations. This is based on a spring-loaded mechanism in which a spring diaphragm is pressurized with compressed air; this shortens it, and the clamping elements release the shaft. When the compressed air is removed, the spring plates at once return to their original position and clamp the shaft with great force. A booster function and additional compressed air supply can further increase the clamping force. RotoClamp offers a fail-safe function: If the pneumatic system fails, the axis is at once clamped with great force.
Users benefit from process advantages
RotoClamp offers users several process advantages that HEMA, with its customized adaptations, can use for most machine concepts. The pneumatic system generates high clamping forces even at low pressures, ensuring high production reliability in precision manufacturing. The fail-safe function provides additional safety and minimizes scrap. HEMA's pneumatic clamping systems are a cost-effective solution, as they eliminate the operating and maintenance costs of a hydraulic system.
