VIBRATION DEVICE FOR FINISHING AND HARDENING PROCESSING Russian patent published in 2015 - IPC B24B31/73 

FIELD: machine building.

SUBSTANCE: device comprises a square hollow working chamber being resiliently mounted on a base and fitted by multithread screw triangular surfaces and unidirectional multithread screw lines arranged along its inner and outer perimeter. The chamber consists of rigidly alternately interconnected four hollow sections in the form of circular sectors and four hollow rectilinear sections. The four hollow sections in the form of circular sectors consist of subsections made from bands which are bent to form quadrangles of different size with two parallel sides being ringed and coupled to free quadrangle sides. The four hollow rectilinear sections are made from a band being bent by straight lines to form identical parallelograms arranged at the band alternately to opposite sides, and being ringed into cylindrical turns coupled to each other by longitudinal edges.

EFFECT: expanded functionality, improved processing efficiency and increased walkway of processed parts and working medium in a chamber.
