DEVICE FOR RUBBING OVER AND SMOOTHING OF SURFACES Russian patent published in 1994 - IPC

FIELD: construction. SUBSTANCE: magnetostriction oscillator 2 is mounted inside case 1. Arch-shaped links of oscillation amplitude amplifier 3, having their working surface cross- section gradually reducing and bent toward a direction perpendicular or inclined to screw clamps 4, are rigidly attached to magnetostriction oscillator 2. Oscillation amplitude amplifiers 3 are interacting by their free ends with the surfaces of screw clamps 4 and are fixed on the surfaces by guiding sleeve 5. Changeable working tool 7 is fixed by screw coupling 6 in screw clamp 4. Screw clamp 4 is connected to case 1 by means of adjusting contraction load springs 8. Removable handle 9, handle 12 and cramp 13 is mounted on case 1. Handle 1 is secured in clamp 10 by screw 11. The lower central section of case 1 is provided with rollers 14 to ensure idle displacement of the device. Oscillator 2 is energized through cable 14. EFFECT: enlarged operating capabilities. 2 cl, 5 dwg
