Abstract

The invention relates to the field of industrial use of ultrasonic vibrations energy and can be applied in machine-building, ship-building and other industries, in particular for the deformation processing surfaces critical structures operating under vibratory loads. Ultrasonic impact treatment tool for part surfaces, comprising a housing having a handle and covered with vibration-proof coating in which via a sliding guide pin for limited movement along the body is placed a glass at one end of which is placed head with movable impact elements fixed with respect to beaker with rapid detachably placed at the other end of the forced cooling system air outlet and the electric supply cable generator of ultrasonic vibrations and in the middle of the annular slit nozzle with a gap and acoustically decoupled placed ultrasonic vibration drive reciprocating movement with the developed heat-exchanged interface sound-path length of which equals 1/4 of strain wave length set along vibration drive formed by the piezoelectric transducer with frequency reducing plates, one of which is integrally integer step transformer of vibrational velocity in which there is provided a possibility of forced cooling system air pass-through via channels from the end of the connecting branch through the slit nozzle with heat-exchange interface and to the inlet working end, wherein the output end communicates with the working head of movable impact elements and carbide is formed, a glass mounted in the housing with the possibility of elastic elements producing pressure drum to the work surface by means of movable bearing with pins fixedly attached to figured notches of the body, and the temperature of the heat transfer surface and the position relative to the housing cup controlled by sensors, moreover in case when the glass and the housing are made from nonmagnetic materials, then the position sensor can be of a magnetic type length of the lower surface of step transformer of vibrational velocity is more than 1/4 of the strain wave length set along vibration drive and equals to the odd quantity of such wave quarters, between the inlet end of the transformer of vibrational velocity and the head of movable impact elements with a hole for compressed air of the forced cooling system there is a movable plane-parallel round disk which diameter is not less than the diameter of the output end of the transformer of vibrational velocity, with is much less than 1/4 of the strain wave length set along vibration drive, cylindrical surface has inclined relatively to the generatrix apertures and is made of hard-alloy material with high value of viscosity, and the pin for glass movement limitation is hollow and has a light-emitting diode that has an ability to radiate on the end surface side of the pin to the internal zone of the ultrasonic tool, moreover the LED turns on by means of additional glass position sensor that controls the zone of optimal clamping force to the working surface. Application of this invention in the impact treatment tools for part surfaces will allow to increase the quality of treatment of part surfaces, increase the durability of the tool and to increase its features.
