Изобретение относитс  к области металлооб работки.The invention relates to the field of metal working.

Известен режущий инструмент, содержащий державку,, режущую пластину, установленную В ее гнезде, крепежный винт с конической головкой и разрезную в осевом направлении втул ку, расположенную в отверстии пластины 1.A cutting tool is known, which includes a holder, a cutting plate, a mounted In its socket, a fixing screw with a conical head and an axially split bushing located in the opening of the plate 1.

Однако этот режущий инструмент сложен в изготовлении.However, this cutting tool is difficult to manufacture.

Цепью изобретени   вл етс  упрощение конструкции резца.The chain of the invention is to simplify the design of the cutter.

Цель достигаетс  тем, что в предлагаемом режущем инструменте прорези разрезной втулки выполнены с переменным шагом так, что образованы лепестки переменной жесткости, причем лепестки с меньшей жесткостью обращены к базовым поверхност м державки, г нижн   часть втулки выполнена цельной с резьбовым отверстием под винт и расположена в отверстии державки.The goal is achieved by the fact that, in the proposed cutting tool, the slots of the split sleeve are made with variable pitch so that petals of variable stiffness are formed, with petals with lower rigidity facing the base surfaces of the holder, g the lower part of the sleeve is made integral with a screw hole and located in the bore of the holder.

, На фиг. 1 изображен описываемый режущий инструмент, вид сверху; на фиг. 2 - разрез А-А на фиг. 1., FIG. 1 depicts the described cutting tool, top view; in fig. 2 shows section A-A in FIG. one.

Режущий инструмент содержит державку 1, па одном конце которой выполнено гнездо с опорными базовыми поверхност ми 2 и 3 под установку и базирование режущей пластиньг 4. В гнезде державки 1 выполнено отверстие, в котором неподвижно установлен прижимной элемент 5, выполненный в виде втулки с внутренней резьбой 6 с одной стороны и трем  осевыми прорез ми 7 с другой. Осевые прорези 7 выполнены через 90° по окружности и образуют два упругих лепестка 8 мало жесткости и один упругий лепесток 9 большей жесткости в сравнении с лепестками 8. Прижимной элемент 5 установлен в гнезде так, что упругие лепестки 8 малой жесткости расположены против базовых поверхностей 2 гнезда. В резьбовом отверстии 6 прижимного элемента установлен винт 10 с конической головкой 11. Между режущей пластиной 4 и опорной поверхностью 3 установлена прокладка 12.The cutting tool contains a holder 1, at one end of which a nest is made with supporting base surfaces 2 and 3 for mounting and basing the cutting insert 4. In the nest of the holder 1 there is a hole in which the clamping element 5 is fixed, made in the form of a sleeve with internal thread 6 on one side and three axial slits 7 on the other. Axial slots 7 are made through 90 ° around the circumference and form two elastic petals 8 with little rigidity and one elastic petal 9 of greater rigidity in comparison with petals 8. The clamping element 5 is installed in the socket so that the elastic petals 8 of small rigidity are located against the base surfaces 2 sockets . In the threaded hole 6 of the clamping element installed screw 10 with a conical head 11. Between the cutting plate 4 and the support surface 3 is installed a gasket 12.

Базирование и крепление режу|цсй пластины в инструменте осуществл етс  следующим образом .Basing and fixing the cutting plate in the tool is carried out as follows.
