General Algorithm for Computing the Theoretical Centering Precision of the Gripping Devices

摘要

The paper shows a study about the theoretical centering precision for gripping devices. The deviation of the absolute axial centering is taken into account as a centering precision parameter and a general computing algorithm is developed for it. For previously developed gripping devices, using parallelogram and four-bar linkages with coupler driven jaws is computed the variation of the axial centering deviation.
