Изобретение относитс к холодной .обработке металлов давлением, а именно к упрочнению и отделочной обработке поверхностей и образованию регул рного микрорельефа. Устройство содержит корпус„ В шпинделе станка установлен двухступенчатый приводной вал с эксцентричным расположением ступеней. Ступень имеет паз дл элементов привода возвратно-поступательного перемещени эксцентрикового элемента с пальцем по пазу эксцентрично расположенной второй, нижней, ступени приводного вала. На этой же ступени установлено водило со свободно посаженным колесом переменного сечени , контактирующим с венцом корпуса и с колесом переменного сечени , установленным на эксцентриковом валу (ЭВ), несущем инструмент дл виброобкат си. ЭВ с инструментом установлен эксцентрично оси нижней ступени двухступенчатого вала в опорах, выполненных на эксцентриковом элементе, установленном на этой же ступени. ЭВ с инструментом вращаетс вокруг собственной оси и вокруг оси верхней ступени приводного вала. При возвратно-поступательном перемещении эксцентрикового элемента от привода возвратно-поступательного перемещени происходит изменение радиуса вращени ЭВ с инструментом относительно оси верхней ступени дв5гхступенчатого приводного вала и одновременное изменение частоты вращени ЭВ е инструментом относи- тельно собственной оси за счет изменени передаточного отношени между венцом корпуса и колесом переменного сечени . 1 з.п. ф-лы, 2 ил. сл 4 Nd СХ5 СПThe invention relates to the cold treatment of metals by pressure, in particular to the strengthening and finishing of surface treatment and the formation of a regular microrelief. The device includes a housing “In the machine spindle there is a two-stage drive shaft with an eccentric arrangement of steps. The stage has a groove for the drive elements of the reciprocating movement of the eccentric element with a finger along the groove of the eccentric second, lower, stage of the drive shaft. At this stage, the carrier was installed with a freely variable-wheel wheel in contact with the crown of the housing and with a wheel of variable cross-section mounted on an eccentric shaft (EV) carrying the tool for vibrating siding. EV with the tool is installed eccentrically to the axis of the lower stage of the two-stage shaft in the supports made on the eccentric element installed on the same stage. The tool EV rotates around its own axis and around the axis of the upper shaft of the drive shaft. During the reciprocating movement of the eccentric element from the reciprocating drive, the rotational radius of the EW varies with the tool relative to the axis of the upper stage of the two-speed drive shaft and simultaneously changes the frequency of rotation of the EE with the instrument relative to its own axis due to a change in the gear ratio between the body crown and the wheel variable cross section. 1 hp f-ly, 2 ill. sl 4 Nd СХ5 СП
