Reconfigurable Clamping Device Based on Muiti-function Link and Hydraulic Cylinder with Built-in Piston Rod

摘要

Reconfigurable clamping devices based on multi-function linkage and rod-less piston cylinder by fluid transmission were introduced. Their working principles have been introduced, and the relevant mechanics calculation formulas were presented. In these devices, rod-less piston cylinder was used as a drive, while multi-function bars and wheels with simple and similar geometric shapes as the basic components. The needs for the clamping of workpieces with different sizes or shapes and requirements for the line-contact or face-contact clamping can be meet by changing the shapes of the basic components and the locations, meanwhile great clamping force can be provided. Due to the rapid reconstruction, the demands of multi-type, variable-volume and short periods can be satisfied.
