The Dynamic Model of the Automatic Clamping Mechanism with a Rotating Input Link

Abstract

Some features of a new design of clamping mechanism drive for automatic fixing of cylindrical objects in metalworking machines are considered. One of the proposed design features is a rotating input link, which receives input energy in the form of rotational motion. The presented drive’s operation is considered a part of the clamping mechanism with a collet chuck. Furthermore, the clamping mechanism’s interaction with a drive of the main movement of a lathe is described. The dynamic model is presented as a system with lumped parameters, consisting of rigid bodies connected by inertialess elastic-dissipative links. The stages of the backlash elimination and conversion of the mechanism elements’ kinetic energy into the system’s stressed state’s potential energy are considered separately. The obtained results can contribute to the development of methods for calculating this type’s structures’ parameters. They can be helpful in the determination of more optimal geometric-mass parameters of the elements of these structures.
