(54) ДВУХЯЕЗВИЙНЫЙ ИНСТРУМЕНТ(54) TWIN-EQUIPMENT TOOLS

Изобретение относитс к метапло , обработке в частности к инструментам дл зубообработки изделий с эвопьвентным профилем, и может быть ИС пользовано дл окончательной обработки и при ремонтно-восстановительных работах.The invention relates to metaplo, processing, in particular, to tools for the processing of products with evipient profiles, and can be used by the IC for final processing and during repair work.

Известен двухлезвийный инструмент с пр мрлинейнымй режущими кромками дл чистовой обработки цилиндрических зубчатых колес, содержащий корпус с двум сменными резцами, опирающимис плоскими гран ми задних прв рхностей части на расположенные под заданными углами к торцу инструмента базовые плоскости, и цилиндрические клинь дл зажима резцов,установленные с возможностью повЬрбтд осевого перемещени в отверсти х корпуса и по резьбовым поверхност м шага центрально в них установленных дифференциальных винтов,ввинченных резьбовыми участками увеличенного шага в резьбовые отверсти корпуса LlJ.A two-blade tool with straight cutting edges for finishing machining of cylindrical gears is known, comprising a housing with two replaceable cutters supported by flat edges of the rear axle portions on the base planes located at given angles to the tool face, and cylindrical wedges for cutting the cutters mounted with the possibility of turning axial movement in the holes of the body and along the threaded surfaces of the pitch of the centrally mounted differential screws screwed into the holes step portions enlarged into threaded holes LlJ housing.

Недостатки этого инструмента низка точность обработки вследствие вли ни переточек резца по передним поверхност м на профиль зубьев, а также отсутствие возможности обработки колес с различной толщиной зубьев и корректировки угла наклона режущих кромок к торцовойплоскости,направленной на компенсацию деформаций cиcтe лы СПИД под воздействием усилий The disadvantages of this tool are low machining accuracy due to the influence of the chisel ridges along the front surfaces on the tooth profile, as well as the inability to handle wheels with different tooth thickness and adjust the angle of inclination of the cutting edges to the end plane, aimed at compensating the deformations of AIDS systems under the influence of efforts

Claims

Twenty pairs and components with the first angle equal to the angle of the point of the cutter in the plane normal to the cutting edge and planks with threaded holes for bushings additionally inserted into the tool with eccentric threaded holes, the planks being movably installed and intended to interact with the supporting elements. FIG. 1 shows a view of the tool in an axial plane parallel to the cutting edge of the first cutter; in fig. 2 is a view in the end plane along section A-A of FIG. 1; in fig. 3 shows a view in an axial plane parallel to the cutting edge of the left cutter; .on FIG. - diagram of the position of the axes of the threaded holes of the movably mounted melt. In case 1, interchangeable cutters 2 and 3t are installed, supporting flat surfaces of the rear surfaces of the ramming bodies with flat edges on the reference planes at the calculated angles oL to the tool face and 5 movably mounted in housing 1 of the strips 6 and 7. Front flat edges of the cutting hour These incisors 2 and 3 also rest on the reference planes 8 and 9 of the strips 6 and 10.; In the threaded holes of the movable strips 6 and 7 there are mounted bushings 11 with eccentric threaded holes, which in turn are movably mounted on the thread of a reduced pitch of differential screws 12 threaded with increased pitch in the holes of the housing 1. Spacing L. between the threaded holes mi (movable strips 6 and 7) are chosen to be shorter than the distance C between the corresponding (zimi threaded holes in the housing, which ensures an independent rotation of the plug П with the eccentricity of the threaded holes at a certain angle. For clamping the cutter The cylindrical wedges 13 and 14 are mounted in case 1 on concentric differential screws 15 and 16. Screwed into the threaded holes of the case, the mechanism works as follows: Before installing the cutters .2 and 3, turning the differential screws 15 and 16 cylindrical, the wedges 13 and 1 lead out turning the differential screws 12 to some extent, release the sleeves 11 of the movable strips 6 and 7. By rotating the sleeves 11 relative to the strips 6 and 7 of the differential screws 12, I adjust the angle oL and the distance between the azow planes 4 and 5. By screwing in the screws 12, the strips 6 and 7 are secured through the sleeves 11, and the incisors and 3 with the anvil of the base front and rear planes of the cutting part are installed in the basic blades A, 8 and 5; 9 respectively. By growing differential screws 15 and 16, the cylindrical wedges 12 and 14 are progressively displaced and the cutters 2 and 3 are clamped. The eccentricity value in the sleeves 11 is equal to half of the required range of adjusting the half edge of the cutting edge relative to the central end plane of the body. The difference between the axial spacings L and L of the pinhole holes in the slats and the body is chosen taking into account the nonbath region of adjusting the calculated angle ot using the following dependency:. C e l L (l-Aol wjwp, where the largest correction angle oL. Using the proposed tool design stabilizes the geometric position of the rectilinear cutting edges of the cutters, regardless of the change in the geometrical dimensions of the cutters themselves, ground on the front or rear surface planes along the entire holder, i.e. to increase the stability of accuracy. In addition, the adjustment of polsnkonyi cutting edges allows you to control the geometric setting when processing worn gears and hardened teeth Unstable hardness wheels on gear cutting machines of normal rigidity Formula of invention A double-blade tool with straight cutting edges for finishing cylindrical wheels, comprising a housing with two replaceable cutters supported by flat edges of the back surfaces of the cutting part on support elements at an angle to the tool face, and cylindrical wedges for clamping the incisors, characterized in that, in order to improve the accuracy of the machining of the wheels and to increase the technological potential of the tool ments, it is provided with additional support elements in contact with the front ploskoe59179786
