摘要： 为了提高能源的利用效率和减少对环境的污染，提出了一种新概念的夹紧装置设计方法．夹紧装置由温控微量位移驱动装置、面积效应行程放大装置和自锁双边单作用增力铰杆机构组成．其原理是：利用半导体制热/制冷快速转换技术使得温度敏感材料产生微量位移，通过基于帕斯卡原理的面积效应行程放大装置，进行100倍左右的放大而变成显著位移，然后作用于过临界点铰杆增力自锁机构上，对工件进行夹紧．这种新概念的夹具装置，不仅能够实现切削加工过程零耗能，而且具有结构简单、能源利用效率高、稳定性好、无噪声污染、自锁性能优良的优点．

Abstract: To enhance energy usage efficiency and reduce environmental pollution, a design method based on a new concept for clamping device was proposed. Clamping device is composed of a temperature-controlled micro-displacement driving device, an area effect stroke amplifier and a self-locking bi-bar single-acting toggle force amplifying mechanism. Its working principle takes the advantage of semiconductor heating/refrigeration converting technology to make thermal-sensitive material generate micro-displacement, then the micro-displacement is amplified to about 100 times to become a noticeable displacement by applying the area effect stroke amplifier based on Pasca's principle. The output displacement and force are transmitted on passing critical point self-locking toggle force amplifying mechanism to clamp the workpiece. The new concept clamp device can not only realize zero energy consuming in cutting process but also has the characteristics of simple structure, high energy efficiency， good stabilization, non-noise contamination and good self-locking property.
Key words: clamping device    temperature controlled micro-displacement driving device    area effect stroke amplifier    toggle force amplifying mechanism    self-locking mechanism
