VIBRATION DEVICE FOR FINISHING AND HARDENING 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. Work chamber is made hollow in form of square with helical surface and with pockets having different polygonal form and dimensions, and made out of rigidly connected in series with each other four hollow sections in form of round sector and four hollow straight sections. The sections in form of round sectors are made out of sub-sections with multifaceted surface having square with same size. Each of four hollow straight sections is made out of at least one strap bent at straight lines and turned in cylindrical turns connected with each other along the longitudinal edges of the strap, creating broken helical lines and broken helical pockets with different polygonal form and size.

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