Изобретение относитс  к станкостроению и может быть использовано дл  модернизации металлорежущего оборудовани .The invention relates to a machine tool industry and can be used to modernize metal-cutting equipment.

Известные борштанги, предназначенные дл  безрисочного вывода режущего инструмента из обрабатываемого отверсти , отличаютс  либо пониженной плоскостью участка борштанги, либо отсутствием фиксированного положени  режущего инструмента.Known boring rods intended for risk-free removal of the cutting tool from the hole to be machined are distinguished either by a reduced plane of the boring section or by the absence of a fixed position of the cutting tool.

С целью безрисочного вывода режущего инструмента из обрабатываемого отверсти  режущий инструмент снабжен механической пружиной, воздействующей на него в сторону отжима от обрабатываемой поверхности.For the purpose of a risk-free output of the cutting tool from the hole being machined, the cutting tool is provided with a mechanical spring acting on it in the direction of spinning from the surface being machined.

На чертеже схематически показана борштанга , осевой разрез.The drawing schematically shows the boring bar, an axial section.

В стержне 1 борштапги выполнена полость 2, в которой помещен поршень 3 с уплотнением 4. На штоке поршн  закреплен резец 5. Поршень упираетс  в гайку 6, имеющую выточку 7, в которой установлена пружина 8, контактирующа  с торцами гайки и поршнем. В стержне борштанги выполнен канал 9, сообщающий полость с источником 10 давлени  рабочей жидкости.In the boring rod 1, there is a cavity 2 in which the piston 3 is placed with a seal 4. A cutter 5 is fixed to the piston rod. A channel 9 is made in the boring bar, which communicates a cavity with the source 10 of the working fluid pressure.

В процессе обработки отверсти  в полость от источника 10 подаетс  под давлением рабоча  жидкость, прижимающа  торец поршн  к торцу гайки. После окончани  растачивани  давление подачи уменьшаетс , и поршень под действием пружины отходит от торца гайки, отвод  режущий инструмент в радиальном направлении, что обеспечивает вывод борштанги из отверсти  без образовани  риски.During processing, the holes in the cavity from the source 10 are supplied under pressure by the working fluid, which presses the end of the piston against the end of the nut. After the end of boring, the feed pressure is reduced, and the piston under the action of the spring moves away from the end of the nut, retracting the cutting tool in the radial direction, which ensures the withdrawal of the boring bar from the hole without forming risks.
