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

FIELD: machine building.

SUBSTANCE: device comprises working chamber with drive resiliently fitted on the bed. The bed is made hollow in form of the square with curvilinear helical surface along the internal perimeter in form of the pockets having curvilinear shape. The work chamber consists of rigidly alternately interconnected four hollow sections in the form of hollow circular sectors and four hollow straight sections. Sections in form of the round sector are made out of straps, on which squares of different dimensions with two parallel sides in for bending lines are crated. The straps are convoluted in form of ring-subsection connected with each other by free sides of the specified squares. The hollow straight sections are made out of strap bend along straight lines at angle to the strap edges, and convoluted in the cylindrical turns with creation of the helical lines along the outside and inside surfaces, and of the helical surfaces with the curvilinear shape in form of the pockets with hemispheric form.

EFFECT: enhanced technological abilities of the device, higher efficiency of parts processing.
