| The traditional clamping mechanism of industry manipulator,When converting from outside to inside clamping, or clamping a workpiece of small size conversion to a larger clamping workpiece, Generally need to design and manufacture, This will significantly delayed delivery cycle. In addition, due to the low-pressure pneumatic drive, in need of large clamping force is a heavy and huge volume of cylinder, and the technical problems exist for a long time. This paper describes a new innovation design idea of reconfigurable pneumatic clamping mechanism based on series-connected force amplifier .Analyses the combination in series force amplifier in the technical characteristic , compare with series-connected force amplifierDesigned clamping device due to the series force amplifier as the basis to combine the advantages of various devices, and the overall layout with built-cylinder, the structure is extremely simple and compact, able to exceed and to maximize efficiency and volume, cost minimization . The pneumatic clamping device to drive the power source, pneumatic drive to clean the air as the transmission medium, as opposed to easy on the environment in terms of pollution of hydraulic transmission, In the protection of the environment has a significant advantage . Using the two-step or three-step force-amplifier, the device solved the shortcoming of lower press result in the smaller force of pneumatic drive system, and thus can be instead of the hydraulic clamping device in certain extent which easily leads to environmental pollution. The graphic example, corresponding formula of output force and mechanics characteristics curve are given which of important reference value and the guide meaning for engineering fields.
