Description

(54) РЕЖУЩИЙ ИНСТРУМЕНТ(54) CUTTING TOOL

1one

Изобретение относитс  к металлообработке и может быть использовано при проектировании инструмента с механическим креплением режущих пластин.The invention relates to metalworking and can be used in the design of a tool with a mechanical fastening of cutting plates.

Известен режущий инструмент, состо щий из корпуса, режущей пластины, прит гиваемой к корпусу посредством головки зажимного винта, коническа  часть которой контактирует с пластинкой, а цилиндрическа  - с поверхностью гнезда корпуса 1. Данна  конструкци  инструмента не обеспечивает фиксированного креплени  режущей пластины, так как ее крепление осуществл етс  линейным контактом - касательна  конической поверхности головки зажимного винтд и точкой на корпусе инструмента .A cutting tool is known, consisting of a body, a cutting plate attracted to the body by means of a clamping screw head, the conical part of which contacts the plate, and a cylindrical part with the surface of the housing of the body 1. This design of the tool does not provide a fixed attachment of the cutting plate, since the fastening is made by a linear contact — the tangent to the conical surface of the head of the clamping screw and a point on the tool body.

Цель изобретени  - повышение надежности фиксированного, креплени  режущей пластины в корпусе инструмента.The purpose of the invention is to increase the reliability of the fixed, fastening the cutting insert in the tool body.

Поставленна  цель достигаетс  тем, что в конструкции режущего инструмента, состо щего из корпуса, режущей пластины и упругого зажимного винт4, головка которог6 контактирует с-корпусом и режущей пластиной , контактна  поверхность головки зажимного винта выполнена с нечетным количеством выступов и впадин.The goal is achieved by the fact that in the design of the cutting tool consisting of the body, the cutting plate and the elastic clamping screw 4, the head of which 6 contacts the body and the cutting plate, the contact surface of the head of the clamping screw is made with an odd number of projections and valleys.

На фиг. 1 представлена предложенна  конструкци  режущего инструмента; на фиг. 2 - вид А на фиг. 1.FIG. 1 shows the proposed design of the cutting tool; in fig. 2 is a view A of FIG. one.

5Режущий инструмент состоит из.корпуса5 Cutting tool consists of body

1, в гнезде которого установлена режуща  пластина 2, прит гиваема  к опорной поверхности корпуса упругим зажимным винтом 3, установленным в корпусе под углом к1, in the slot of which a cutting plate 2 is mounted, is attracted to the bearing surface of the housing by an elastic clamping screw 3 installed in the housing at an angle to

10 передней поверхности режущей пластинки. Контактна  поверхность 4 зажимного винта 3 выполнена конической с нечетным количеством впадин и выступов. Между головкой зажимного винта 3 и его резьбовой частью выполнена шейка меньшего диаметра, что10 front surface of the cutting plate. The contact surface 4 of the clamping screw 3 is made conical with an odd number of depressions and protrusions. Between the head of the clamping screw 3 and its threaded part there is a neck of a smaller diameter, which

5 обеспечивает упругие свойства зажимного винта.5 provides the elastic properties of the clamping screw.

При закреплении режущей пластины в момент контакта с ней одного из выступов 20 головки винта ось последнего упругого отжимаетс , пропуска  выступы головки винта , после чего за счет упругого последействи  ось винта возвращаетс  (не полностью), а режуща  пластина оказываетс  в контактеWhen fixing the cutting plate at the moment of contact with it of one of the protrusions 20 of the screw head, the axis of the last elastic is pressed, the protrusions of the screw head are skipped, after which, due to the elastic follow-up, the axis of the screw returns (not completely) and the cutting plate comes into contact
