SCHUNK, the competence leader for clamping technology and gripping systems has developed the compact VERO-S NSA quick-change pallet module for automated machine loading. At a repeat accuracy of less than 0.005 mm it allows a fully automated pallet change of the highest precision. The clamping system from the innovative family-owned company is extremely thin, and leaves enough space for the workpiece in the machine and for axis motions. If required, it can be integrated in the machine table.
In order to avoid chips and dirt from endangering the automated changing process, a forced air flow cleans the face during pallet change, and ensures a chip-free contact surface. Subsequently, centering rings take over precise positioning. The module is locked via two clamping slides, providing form-fit, self-locking fixing of the centering ring. Via an air pressure monitoring system, every process step can be monitored reliably: Module open, module closed, and pallet presence.
High pull-down forces
In order to increase product life and process reliability, the functional parts of the NSA plus such as base body, clamping pin, and clamping slide are made of hardened stainless steel. If the turbo function is actuated, the pull-down force of the NSA plus increases up to 30.000 N, and the holding force to more than 100.000 N. The SCHUNK quick-change pallet modules are equipped with a patented double angled clamping stroke, and therefore provide for high pull-down forces. Even in case of demanding volume machining, the robust pallet module ensures reliable and precision clamping. It also absorbs extreme shear forces, whereby the workpiece does not have to change its position. The pallet removal has been also developed in a sophisticated way: The module is unlocked at a pneumatic system pressure of 6 bar. At the same time, a pin lifts the pallet, and thus simplifies the change by a robot or operator.
