Изобретение относитс к металлорежущим инструментам, например фасонным дисковым резцам.The invention relates to metal-cutting tools, such as shaped disk cutters.

Известен сборный резец, включающий корпус и режущую часть с посто нной формой поперечного сечени , выполненной в виде разомкнутого кольца, размещенного в кольцевой проточке корпуса и закрепленного на державке посредством оси 1.A collection cutter is known, comprising a body and a cutting part with a constant cross-sectional shape, made in the form of an open ring, placed in an annular groove of the body and fixed on the holder by means of axis 1.

Недостатком известных резцов вл етс невозможность обеспечени регулировани вылета режущей части.A disadvantage of the known incisors is the impossibility of providing adjustment of the overhang of the cutting part.

Цель изобретени - обеспечение возможности регулировани вылета режущей части.The purpose of the invention is to provide the ability to control the departure of the cutting part.

yka3aHHaff цель достигаетс тем, что резец снабжен толкателем, выполненным в виде рычага, установленного на оси с возможностью поворота и фиксации.Yka3aHHaff goal is achieved by the fact that the cutter is equipped with a pusher, made in the form of a lever mounted on an axis with the possibility of rotation and fixation.

На фиг. 1 изображен предлагаемый резец; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3 - виид Б на фиг. 2.FIG. 1 shows the proposed cutter; in fig. 2 is a section A-A in FIG. one; in fig. 3 - the view B in FIG. 2

Сборный резец содержит режущую часть 1, выполненную в виде разомкнутого кольца 2, размещенного в круговой проточке 3, выполненной на торцовой поверхности обоймы 4, имеющей пр моугольный вырез аThe cutting tool contains a cutting part 1, made in the form of an open ring 2, placed in a circular recess 3, made on the end surface of the sleeve 4, having a rectangular cutout

на уровне оси центров станка, а также срез б открывающий режущую часть 1 в зоне ее взаимодействи с обрабатываемой деталью. Обойма 4 жестко св зана с державкой 5, имеющей квадратное поперечное сечение 5 дл креплени в резцедержателе станка.at the level of the axis of the centers of the machine, as well as cut b, opening the cutting part 1 in the area of its interaction with the workpiece. The yoke 4 is rigidly connected to the holder 5 having a square cross section 5 for mounting in the tool holder.

В обойме 4 закреплена ось 6, на которой установлен с возможностью углового поворота толкатель кольцевой режущей части, выполненный в виде рычага. 7, сопр женный с задним торцом кольца, причем конец рычага выступает за пределы обоймы. Цередний рабочий конец режущего кольца заточен в соответствии с заданной геометрией и профилем обрабатываемой деталии.In the holder 4, an axis 6 is fixed, on which the pusher of the annular cutting part, made in the form of a lever, is mounted with the possibility of angular rotation. 7, conjugated with the rear end of the ring, with the end of the lever protruding beyond the cage. The first working end of the cutting ring is sharpened in accordance with a given geometry and profile of the workpiece.

На оси 6 посредством гайки 8 установлена прижимна щайба 9, сопр женна с обоймой через кольцевую режущую часть 1 и тарельчатую пружину 10, установленную в проточке 11 обоймы 4.A pinch clamp 9 is mounted on the axis 6 by means of a nut 8, and is associated with the holder via an annular cutting part 1 and a disk spring 10 installed in the groove 11 of the holder 4.

Claims

The collecting tool is installed by means of the holder 5 into the tool holder 12 of the lathe, adjusted to size by means of a limb, which is provided with a screw for lateral movement of the upper slide and is processed by the product. In the case of cutting the cutting part 1, the cutter is removed from the machine, loosening the nut 8. In this case, the clamping washer 9 together with the lever 7 moves away from the sleeve 4 along the axis 6 under the action of the belleville spring 10 and releases the cutting part 1. I will act on the rear end of the cutting ring 2 with the lever 7, it is moved in the groove 3 of the holder 4 by the required size determined by the allowance for re-cutting of the cutter along the front face. After re-cutting the cutter, tighten the nut 8, which acts on the pressure plate 9, which presses the disk spring 10. As a result, the pressure plate 9 9 is secured to the cutting portion 1 in the groove 4. The cutter holder 3 mounted in the tool holder 12 and the workpiece until the next blunting its cutting portion. The lever 7, which is the pusher of the cutting part 1, at the beginning of use of the cutter occupies position I (Fig. 1), as it is refilled it rotates on axis 6, occupies intermediate position II, and when it occupies position III corresponding to the shortest length of cutting part 1, the latter must be replaced by setting the lever 7 back to position I. Formula of the invention The assembly, cutter, including the body and the cutting part with a constant cross-sectional shape, made in the form of an open ring, placed in the ring groove of the body and secured on the holder by means of an axis, characterized in that, in order to enable adjustment of the overhang of the cutting part, the cutter is provided with a pusher made in the form of a lever mounted on the axis with the possibility of rotation and fixation.
