The Clamping System Based on Giant Magnetostrictive Material and Displacement Amplifier with Area Effect
The green fixture is the research focus, but the current research is centralized on the fixture driven by the air. It will lead to a noise polution and a small clamping force. Using the green electromagnetic conversion technology, a new clamping system to clamp the workpiece is provided, which is composed of the giant magnetostrictive material as working medium and the displacement amplifier with the area effect. This device can realize the flexible configuration of clamping at multi-place, for multi-workpiece and in multi-direction. Furthermore, this clamping system using the A/D converter and the sensor technology of pressure and displacement to collect the relative data, the collected data can to be putted in the computer and be processed，so it is easy to control the clamp force and clamping displacement intelligently.
