Description

. Изобретение ОТНОСЯТСЯ к металлообработке , в частност к металлорежущему инструменту дл чистового нарезани конических и гипоидных колес, с криволинейнБоо зубь ми.. The invention relates to metalworking, in particular to a metal-cutting tool for finishing cutting conical and hypoid wheels, with curvilinear teeth.

По основному авт.св. 524627 известна резцова головка дл шютовой обработки зубьев, в корпусе которой выполнены радиальные пазы, несущие резщ: и опорные поворотные сегмент f . имеющие криволинейную по ерхность . В радиальных паэгис корпуса помещены регулировочные клинь с пазами , в которых устансюлены опорныеi сегменты, взаимодействующие своей криволинейной поверхностью с соответствующей поверхностью паза t 3According to the main auth. 524627 a known cutting head for a side-by-side machining of teeth, in the casing of which radial grooves are made, bearing carving: and supporting rotary segments f. having a curved surface. In the radial paegis of the body there are placed adjusting wedges with grooves in which the supporting segments are installed, interacting with their curvilinear surface with the corresponding surface of the groove t 3

Однако процесс.регулировки резцов. в корпусе головки вл етс сравнительно трудоемкой операщией, так как про исходит в три этапа: радиальна регулировка резцов, установка их на заданный угол профил и затам вновь ра-. диальиа поднастройка резцов. Крс де того, по окончании регулировки резцов и зат гивании крепежных винтов углова установка резца может быть нарушена из-за неравномерности усили зат жки крепежных винтов.However, the process.adjusting the incisors. in the head casing, it is a relatively labor-consuming operative, since it occurs in three stages: radial adjustment of the incisors, their installation at a given angle of profile, and cost again. dialia tune incisors. After that, after adjusting the incisors and tightening the fastening screws, the angular installation of the incisor can be broken due to the unevenness of the tightening of the fastening screws.

Цель изобретени - снижение трудоемкости к повышение точности регулировки резцов.The purpose of the invention is to reduce the labor intensity to improve the accuracy of adjustment of the incisors.

Цель достигаетс тем, ,что рабоча поверхность сегмента выполнена как часть боковой поверхности цилиндра с осью вращени , проход щей через середину профилирующей режущей кромки резца, а резец установлен с возможнос10 тью поворота вокруг зтой оси.The goal is achieved by the fact that the working surface of the segment is made as part of the lateral surface of the cylinder with the axis of rotation passing through the middle of the main cutting edge of the tool, and the tool is installed with the possibility of rotation around this axis.

В радиальных пазах корпуса 1 головки установлены сегменты 2, опираю-, щиес на кольцо 3 и контактирующие своей поверхностью, выполненной как In the radial grooves of the body 1 of the head, the segments 2 are mounted, resting on the ring 3 and contacting with their surface made as

Режуща пластина 6 фиксируетс 20 is a part of the lateral surface of the cylinder, with a cylindrical support surface of the cutter holder 4. The cutting edge 4 in the head housing 1 is fixed by means of screws 5. The cutting plate 6 is fixed

Радиальную настройку резцов 4 осуществл ют регулировочшлми клинь ми 9, перемещаемыми винтами 10.25 in the holder of the cutter 4 with the clamp 7 and winpol 8. Radial adjustment of the cutters 4 is carried out by adjusting wedges 9 moved by screws 10.

Claims

The adjustment of the incisors in the head is carried out as follows. . The indicator tip is placed at a point lying in the middle of the profiling cutting edge of the plate 6, through which the axis of rotation of the cylindrical support surface of the tool holder 4 passes. Moving the adjusting wedge 9 radial setting of the tool 4 is performed. Then, lightly tapping the head of the fixing screw 5 (screw 5, with slightly tightened) angular adjustment of the cutter 4 is performed. A conical washer 11 at atet / 1 moves along the cylindrical surface of the groove of the support ring 3. The cylindrical surface of the groove of the supporting ring The 3 in the nominal position is centered with the cylindrical bearing surface of the cutter 4, however, when the cutter 4 is radially adjusted, there is not a significant eccentricity, which is compensated for by the conical screws 5 of the conical 11 and the spherical 12 washers. The groove of the support ring 3 opposite the master cutter 13, opposite the master cutter 13, has not a cylindrical, but a flat surface in contact with the washer 14 of the fastening screw 5. Therefore, the master cutter has a constant angular position relative to the axis of rotation of the cutter Head, With this structure, the cutter head is no need for the adaptation about radial reztsbv after their angular adjustment, since the point on the cutting edge, wherein the indicator is mounted at the tip of the radial adjusting incisors during their uglovoy.nastroyki remains stationary. When tightening the fixing screw, the cutter reliably presses against the base surfaces of the head housing, and the uneven tightening force does not affect the angular position of the cutters, since the longitudinal axis of the fixing screw lies in the radius plane of the cylindrical support surface of the cutter, which allows It reduces labor intensity and improves adjustment accuracy. Claims of the invention: Cutting head according to auth ... No. 524627, characterized in that, in order to reduce labor intensity and improve the adjustment accuracy of the incisors, the working surface of the segment is made as part of the lateral surface of the cylinder, the axis of which passes through the middle of the main cutting edge of the incisor, and the cutter is installed with the possibility of rotation around this axis.
