Smarter clamping and gripping
In the course of digitalization, the trend goes to highly automated, fully networked and autonomous manufacturing systems.

Due to their exposed position, the clamping devices and gripping systems play a special role in this process: They enable more flexible processes, as well as permanent process monitoring, and optimization directly on the workpiece.

After several studies in the field of smart gripping, SCHUNK is now presenting for the first time how sensitivity, connectivity, and a high degree of functional integration become key factors in the real-time monitoring of clamping devices.

For example, clamping force, clamping path, or vibration behavior during machining can be permanently recorded, and analyzed. If deviations occur while a process is running, the machining parameters can be adapted automatically in real time, based on the detected data.

With the aid of various intelligent clamping devices, it becomes clear what the future will bring us:

Monitoring of pull-down force, clamping slide position, and workpiece presence The smart quick-change pallet module SCHUNK VERO-S NSE-S3 138 enables permanent monitoring of the pull-down force and clamping slide position.

For this purpose, strain gauges, measuring amplifiers, and inductive analog sensors were integrated directly into the module. Furthermore, the presence of workpieces or clamping pallets are detectable by means of inductive proximity switches.

This ensures that the entire clamping process runs under optimum conditions. Power supply and signal transmission takes place cable-based via spring contacts. Since the measured values are output as analog signals (0 to 10 V DC), simple signal processing is possible. The complete intelligence is integrated into the module in a way that the dimensions completely match those of the conventional VERO-S NSE3.

Variable clamping force
Going one step further, we have the clamping force block SCHUNK TANDEM KSE 100. Beside the integrated monitoring of the clamping path and clamping force, this intelligent powerhouse is also capable of individually adjusting the clamping force and position of each of the chuck jaws to the respective workpiece.

The advantage: Chuck jaws can be pre-positioned in the ongoing process, thus reducing the cycle time. In addition, it is possible to reduce the clamping force on deformation-sensitive parts in order to prevent deformations or damage to the surface. The required sensor technology is also fully integrated into the component.
