Green And Intelligent: Electromechanical-hydraulic Integrated Clamping Device Based On Thermal Sensitive Material

摘要

The fluid-driven clamping devices extensively used in the manufacturing industry nowadays are unable to adapt to the development requirements for green manufacturing technology owing to their low energy utilization, severe problems of noise and environment pollution. This article describes a clamping technology sparing the need of hydraulic pump and air compressor. It causes the thermal sensitive material to quickly expand or shrink linearly with the help of semiconductor heating/refrigeration conversion technology; then with the area effect stroke amplifier, the linear extension generated by the material is amplified around 100 times, and is output and passed to the clamping element in a linear motion manner to clamp the workpiece. This clamping device is an intelligent controlled electromechanical-hydraulic integrated system, featuring high energy utilization, extra low noise and fluid leakage etc.
