FIELD: machine engineering, possibly different manufacturing operations with use ultrasonic oscillations. ^ SUBSTANCE: apparatus includes acoustic system, elastic time-lag member system, movable sleeve, union nut, detachable boss. Acoustic system includes ultrasound irradiator with working tip in its end, magnetostriction transducer, concentrator and changeable resonance wave guides at end side of concentrator. Magnetostriction transducer connected with concentrator, system of elastic time-lag members and changeable sleeve are mounted in housing. System of elastic time-lag members is made with possibility of controlling effort for pressing ultrasound irradiator to treated surface. Said system includes secured to end of magnetostriction transducer and designed for full inner reflection of energy of ultrasound irradiator, spring arranged along lengthwise axis of acoustic system and shaped cover plate with insulation springy member. Movable sleeve is adjoined with acoustic system and it is arranged at side opposite relative to elastic time-lag member system of magnetostriction transducer. Union nut is arranged on outer end side of housing at side of elastic time-lag member system. Detachable boss is arranged on outer side of housing and it is designed for securing apparatus to machine tool in stationary operation mode. Changeable resonance wave-guides are used for providing necessary oscillating shifts and stresses transmitted to treated surface depending upon manufacturing process demands. Hydraulic collars are arranged on movable sleeve. Elastic time-lag member system includes in addition piston, bolt coupled with piston and arranged along lengthwise axis of acoustic system, seals arranged between housing and lateral walls of piston for providing fluid-tightness of housing. Ultrasound irradiator is mounted on end of one of changeable resonance wave-guides, its working tip is changeable and it has different shape depending upon demands of manufacturing process. Spring of elastic time-lag member system is changeable, its geometry size and material are selected according to demands of manufacturing process. ^ EFFECT: enlarged manufacturing possibilities, improved operational reliability of apparatus. ^ 1 dwg |
