Abstract

Изобретение относитс к области машиностроени , в частности к устройствам дл обработки материалов резанием. Целью изобретени вл етс расширение технологических возможностей за счет обеспечени возможности обработки отверстий. Устройство дл механической обработки содержит корпус 1 и механизм дл поворота и зажима режущих пластин 2 и 3. Т-образна т га 4, на одном конце которой закреплена планка 5, кинематически св зана с приводной гайкой 6. При затуплении режущих кромок устройство отводитс из зоны обработки, гайка 6 тормозитс . Устройство поворачиваетс против часовой стрелки, и планка 5 перемещаетс вместе с т гой 4 в крайнее левое положение. Режущие пластины 2 и 3 выход т из контакта с призматическими пазами корпуса устройства. В это врем ось, на которой установлена режуща пластина, посредством зубчатой втулки поворачиваетс . Затем устройство поворачиваетс в другую сторону, Т-образна т га перемещаетс в крайнее правое положение, а режущие пластины при этом благодар фиксаторам не поворачиваютс . Происходит зажим режущих пластин. 9 ил.The invention relates to the field of mechanical engineering, in particular to devices for cutting materials. The aim of the invention is the expansion of technological capabilities by providing the possibility of machining holes. The machining device comprises a housing 1 and a mechanism for rotating and clamping cutting plates 2 and 3. A T-shaped rod 4, at one end of which a bar 5 is fixed, is kinematically connected with a drive nut 6. When the cutting edges are blunt, the device is removed from the zone processing, nut 6 brakes. The device is rotated counterclockwise, and the bar 5 moves with the harness 4 to the leftmost position. The cutting plates 2 and 3 come out of contact with the prismatic grooves of the device body. At this time, the axis on which the cutting plate is mounted is rotated by means of the gear sleeve. Then the device rotates in the other direction, the T-shaped ha moves to the extreme right position, and the cutting plates are not rotated due to the clamps. Clamping cutting plates. 9 il.
