Abstract

Универсальный демпфирующий резец с управляемой жесткостью, содержащий режущую пластину и узел ее крепления, державку с выборкой в ней и вставку из материала с высоким демпфированием, снабжен металлической оправкой и контейнером, причем режущая пластина узлом ее крепления жестко фиксирована на верхней поверхности оправки, выполненной в виде прямоугольного параллелепипеда и размещенной в контейнере, при этом верхняя поверхность оправки установлена выступающей над контейнером без соприкосновения с ним режущей пластины и узла ее крепления, а контейнер с оправкой расположен в выборке, выполненной по форме контейнера и ориентированной по нормали к верхней плоскости переднего конца державки с обеспечением отсутствия контактирования режущей пластины и узла ее крепления на оправке с державкой, отличающийся тем, что контейнер изготовлен из вулканизированного материала с образованием замкнутой эластичной оболочки с сообщаюмися полыми боковыми стенками и днищем прараллелепипеда с внутренними размерами, равными поперечным размерам оправки, а во внешней стенке днища закреплен цилиндрический штуцер, расположение контейнера с оправкой произведено свободно с зазорами в выборке, имеющей в дне сквозное отверстие диаметром, большим диаметра штуцера, который пропущен соосно с отверстием, при этом через штуцер закачан сжатый воздух в полости днища и боковых поверхностей замкнутой эластичной оболочки контейнера до заполнения ею зазоров между выборкой, самоцентрирования оправки на одинаковых расстояниях от стенок и дна выборки, а также создания необходимого избыточного давления для образования единой механическойA universal damping cutter with controlled stiffness, containing a cutting insert and its mount, a holder with a selection in it and an insert made of high damping material, is equipped with a metal mandrel and a container, and the cutting insert is rigidly fixed on the upper surface of the mandrel in the form of a rectangular parallelepiped and placed in the container, while the upper surface of the mandrel is installed protruding above the container without touching the cutting insert and its mount ia, and the container with the mandrel is located in a sample made in the shape of the container and oriented normal to the upper plane of the front end of the holder to ensure that the cutting insert and its attachment site on the mandrel are not in contact, characterized in that the container is made of vulcanized material to form closed elastic shell with communicating hollow side walls and the bottom of the praralelepiped with internal dimensions equal to the transverse dimensions of the mandrel, and fixed in the outer wall of the bottom flange is a cylindrical fitting, the arrangement of the container with the mandrel is made freely with gaps in the sample having a through hole with a diameter greater than the diameter of the fitting, which is passed coaxially with the opening, and compressed air is pumped through the fitting into the cavity of the bottom and side surfaces of the closed elastic container shell up to filling it with gaps between the sample, self-centering the mandrel at equal distances from the walls and the bottom of the sample, as well as creating the necessary overpressure to form a single mechanical coy

Claims

A universal damping cutter with controlled stiffness, containing a cutting insert and its mount, a holder with a selection in it and an insert made of high damping material, is equipped with a metal mandrel and a container, and the cutting insert is rigidly fixed on the upper surface of the mandrel in the form of a rectangular parallelepiped and placed in the container, while the upper surface of the mandrel is installed protruding above the container without touching the cutting insert and its mount ia, and the container with the mandrel is located in a sample made in the shape of the container and oriented normal to the upper plane of the front end of the holder to ensure that the cutting insert and its attachment site on the mandrel are not in contact, characterized in that the container is made of vulcanized material to form closed elastic shell with communicating hollow side walls and the bottom of the praralelepiped with internal dimensions equal to the transverse dimensions of the mandrel, and fixed in the outer wall of the bottom flange is a cylindrical fitting, the arrangement of the container with the mandrel is made freely with gaps in the sample having a through hole with a diameter greater than the diameter of the fitting, which is passed coaxially with the opening, and compressed air is pumped through the fitting into the cavity of the bottom and side surfaces of the closed elastic container shell up to filling it with gaps between the sample, self-centering the mandrel at equal distances from the walls and the bottom of the sample, as well as creating the necessary overpressure to form a single mechanical of a mandrel-container system with injected compressed air - a holder, with the possibility of remote stepless control of the stiffness of the cutter by changing the pressure of compressed air in a closed elastic container shell, in addition, in the space between the attachment point of the cutting insert

on the mandrel and the upper plane of the front end of the holder is installed with a preliminary compression stress an insert of material with high damping.
