VIBRATION-PERCUSSION TOOL WITH ULTRASONIC EXCITATION Russian patent published in 2002 - IPC

FIELD: manual tools with ultrasonic drive for vibration-percussion treatment of surfaces for further plastic deforming of it. SUBSTANCE: tool includes housing, elastic vibration-proof gaskets, excitation source having magnetostrictive converter and waveguide transformer and arranged inside housing with possibility of reciprocation motion relative to it. Tool also includes holder with strikers mounted coaxially relative to waveguide transformer and air type cooling system. Excitation source is placed in sleeve mounted on sliding guides joined with housing in such a way that there is gap between outer surface of sleeve and inner surface of housing. In such tool harmful influence of vibration upon operator is lowered. EFFECT: enhanced functional effectiveness of tool. 2 cl, 10 dwg
