Изобретение относитс к режущему инструменту и может быть испол зовано в деревообрабатывающ€ й промьшшеннос ти,The invention relates to a cutting tool and can be used in woodworking industry.

Цель изобретени - повьшение срока службы резцов.The purpose of the invention is to increase the service life of the incisors.

На фиг. 1 показана фреза, общий вид; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - сечение Б-Б на фиг. 1, на фиг. 4 - резец фрезы; на фиг. 5 промежуточный элемент} на фиг. 6 - диск с фиксатором, вид сбоку.FIG. 1 shows a milling cutter, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 is a section BB in FIG. 1, in FIG. 4 - cutter cutter; in fig. 5 an intermediate element} in FIG. 6 - a disk with a clamp, side view.

Торцова фреза состоит из корпуса 1, на котором закреплена обойма 2. Внутри обоймы размещены резцы 3, между которыми по окружности расположены промежуточные элементы 4, имеющие выступы 5, расположенные в -кольцевых пазах 6 корпуса 1. Промежуточные элементы 4 имеют пазы 7 дл размещени резцов 3. Внутри обоймы 2 с возможностью свободного вращени смонтирована втулка 8, котора фиксируетс в осевом направлении пружинным кольцом 9. Втулка 8 имеет гнезда ГО под ключ, на094382The face milling cutter consists of a body 1 on which the holder 2 is fixed. Inside the holder there are cutters 3, between which circumferentially intermediate elements 4 are located, having protrusions 5 located in the annular grooves 6 of body 1. Intermediate elements 4 have grooves 7 for placing cutters 3. Inside the casing 2, the sleeve 8 is mounted for free rotation, which is fixed in the axial direction by a spring ring 9. The sleeve 8 has turnkey sockets, 094382

ружную резьбу, на которой размещен диск 11 с внешним кольцевым выступом 12 и фиксатором 13. Хвостовики резцов 3 вьтолнены с пазами 14 дл The gun thread, on which is placed a disk 11 with an external annular protrusion 12 and a latch 13. The shanks of the incisors 3 are made with grooves 14 for

5 взаимодействи с кольцевым выступом 12 диска 11. Обойма 2 выполнена в виде гайки и снабжена нажимным кольцом 15 дл взаимодействи с промежуточными элементами 4 по по10 верхност м 16.5 interacting with an annular protrusion 12 of the disk 11. The yoke 2 is made in the form of a nut and provided with a pressure ring 15 for interacting with the intermediate elements 4 of 10 and 16 surfaces.

Сборка фрезы осуществл етс следующим образом.The assembly of the milling cutter is carried out as follows.

В корпусе фрезы устанавливаетс втулка 8 и фиксируетс в осевом на (5 правлении пружинным кольцом 9, после чего навинчиваетс диск I с внешним кольцевым выступом Г2 и фиксатором 13. При перемещении резцы наход тс в незажатом состо нии в пазах про20 межуточных элементов.The sleeve 8 is installed in the cutter body and fixed in the axially on (5th direction by the spring ring 9), after which the disk I is screwed with the external annular ledge G2 and the clamp 13. When the cutters are moved, they are in an open position in the grooves of the intermediate elements.

Использование предлагаемой фрезы позволит увеличить не менее, чем на 20% допустимое число переточек, что позвол ет уменьшить расход дорого25 сто щего инструментального материала .The use of the proposed milling cutter will allow an increase of not less than 20% of the permissible number of regrindings, which allows reducing the consumption of expensive instrumental material.

Claims

A face milling cutter comprising a housing on which a clip is fixed, cutters located inside the clip, between which circumferentially there are intermediate elements having protrusions located in the annular grooves of the housing, characterized in that, in order to increase the life of the cutters, on the housing inside the sleeve with the possibility of rotation is mounted with an external thread sleeve on which a disk with an external annular protrusion and a latch is placed, 'the cutter shanks being made with grooves for interacting with the annular protrusion, and the ferrule It executes a nut and the pressure ring is provided for interacting with the intermediate elements.

Fi.1

1209438 ² male thread on which the disk 11 with an external annular protrusion 12 and a latch is placed 13. The shanks of the cutters 3 are made with grooves 14 for

5 interaction with the annular protrusion 12 of the disk 11. The holder 2 is made in the form of a nut and is equipped with a pressure ring 15 for interaction with the intermediate elements 4 along 10 surfaces 16.

Assembly of the cutter is as follows.

A sleeve 8 is installed in the mill body and fixed in the axial direction by a spring ring 9, after which a disk 11 with an external annular protrusion G2 and a clamp is screwed

13. When moving, the cutters are in a loose position in the grooves of

20 intermediate elements.

Using the proposed cutter will allow you to increase by at least 20% the permissible number of regrindings, which reduces the consumption of expensive25 tool material.
