Symmetric Beauty: Three-steps Force Amplified Clamping Device Based on Lever-Toggle Mechanism Driven by Pneumatic Muscle

Abstract

Compared with the traditional rigid pneumatic cylinder, the pneumatic muscle has many outstanding advantages such as big initial tension, smooth movement, no relative motion component, lightweight. However, it can only provide the tension, can not provide the thrust force; it is a oneorientation output force component. In this paper, use pneumatic muscle as drive component, combined with lever-toggle mechanism, a new type of three-steps force amplified clamping device has been innovated. The working principle of the clamping device is analyzed. Some corresponding mechanics calculating formulas of output force are provided in this paper too. This device has a good effect of force amplifying and no contamination pollution; it is a green-oriented clamping device.
