Abstract
Изобретение относитс к обработке металлов резанием и может быть использовано дл получени точных отверстий, например , при расточке бурильных труб. Цель изобретени - повышение стойкости инструмента путем исключени заклинивани его и поломки.в процессе вывода инструмента из зоны обработки. На штоке 1 на игольчатых подшипниках 2 установлен корпус 3. В конических пазах 4 корпуса 3 установлены сухари 5, в которых выполнены конические пазы 6. Угол конической поверхности последних противоположен углу конической поверхности пазов 4. В пазах 6 установлены направл ющие 7. Сухари 5 и направл ющие 7 подпружинены в продольном направлении пружинами 8 и 9, а ход ограничен кожухом 10.3 ил.The invention relates to metal cutting and can be used to produce precise holes, for example, when drilling boring pipes. The purpose of the invention is to increase the tool life by eliminating its jamming and breaking. In the process of taking the tool out of the treatment area. A housing 3 is mounted on the needle bearings 2 on the bearings 1. In the conical grooves 4 of the housing 3 there are crackers 5 in which the tapered grooves 6 are made. The angle of the conical surface of the latter is opposite to the angle of the conical surface of the grooves 4. the guides 7 are spring-loaded in the longitudinal direction by the springs 8 and 9, and the stroke is limited by the casing 10.3 Il.
