Green clamping devices based on two-step orthogonal toggle force amplifier driven by pneumatic muscle

As a new kind of flexible pneumatic actuator using clean compressed air as working medium, pneumatic muscle has many particular characteristics comparing with pneumatic cylinder. It can well accord with the development of green transmission technique. Combing pneumatic muscle with different kind of mechanical force amplifier is a practical and creative design method. According to this method, five kinds of green pneumatic clamping devices based on two-step orthogonal toggle force amplifier driven by pneumatic muscle are introduced. Their working principles and characteristic features are analyzed and corresponding mechanics calculating formulae are also given respectively.
