VIBRATION APPARATUS FOR FINISH AND STRENGTHEN WORKING Russian patent published in 2008 - IPC B24B39/00 

FIELD: manufacturing processes in machine engineering, namely vibration apparatuses for finish-strengthen working at static-pulse loading of deforming springy tool.

SUBSTANCE: tool includes holder where deforming member is arranged, vibrator with individual drive and springs for static action of deforming member upon worked surface. Deforming member is in the form of coiled cylindrical spring with constant pitch mounted in axle with use of elastic damping base. Vibrator is in the form of shaft on outer surface of which coiled cylindrical spring with variable pitch is rigidly fixed. Said axle with deforming member is mounted in bearing assemblies in holder with possibility of free rotation. Shaft of vibrator is mounted in holder with possibility of rotation from individual drive for realizing alternating contact of turns of variable-pitch coiled cylindrical spring with turns of constant-pitch coiled cylindrical spring.

EFFECT: enlarged manufacturing possibilities.
