Известен зубообрабабывающий станокKnown gear-cutting machine

дл обработки цилиндрических колес пальцевой фасонной фрезой, установленной в подвижной фрезерной головке, котора смонтирована на пр молинейных направл ющих станины и приводитс в движение посредством кулачкового механизма, кинематически св занного со шпинделем заготовки. Последний получ&ет непрерывное вращение от двигател привода подачи, а настройку передаточного от ношени кинематической цепи, св зывающей шпиндель заготовки и кулачок привода фрезерной головки, осуществл ют при помощи сменных зубчатых колес.For machining cylindrical wheels with a finger-shaped milling cutter mounted in a movable milling head, which is mounted on a straight guide frame and driven by a cam mechanism kinematically connected with the workpiece spindle. The latter received & n continuous rotation from the feed drive motor, and the adjustment of the transfer ratio of the kinematic chain, connecting the workpiece spindle and the milling drive drive cam, is carried out using interchangeable gears.

Недостатком такого станка вл етс длительность процесса настройки, включающего в себ установку требуемого набора сменных зубчатых колес и замену кулачка .The disadvantage of such a machine is the length of the adjustment process, including the installation of the required set of interchangeable gears and the replacement of the cam.

С целью сокращени тфодолжительности и упрощени процесса наладки в предложенном станке в кинематическую иепь, св аы вающую шпиндель заготовки с приводом пе ремещени фрезерной головки, включены два параллельных ведущих вала, вращающих- с в одну сторону и несуилих жестко закре1 ленные на них зубчатые колеса, которые расположены на одном из валов в пор дке . возрастани , а на втором - в пор дке убывани их наружного диаметра; между ведущими валами установлен ведомый шлицевав вал, снабженный аксиально-подвижным блоком накидной шестерни, зацепл емой с одним из зубчатых колес ведущих валов. В кинематическую цепь включена также ступенчата коробка передач с переключаемыми зубчатыми парами.In order to reduce the duration of time and simplify the process of adjustment in the proposed machine to the kinematic field, which connects the workpiece spindle with the movement of the milling head, two parallel drive shafts are rotated; arranged on one of the shafts in order. increase, and in the second, in order of decreasing their outer diameter; Between the drive shafts, there is a driven slotted shaft, fitted with an axially movable block of the pinion gear, engaged with one of the gears of the drive shafts. A kinematic chain also includes a manual gearbox with selectable gear pairs.

Claims

a rod 5, the roller of which is in contact with the wedge cam 6. The latter receives a reciprocating horizontal movement from the crank mechanism with an adjustable eccentric 7. The spindle of the product 8, bearing the workpiece, is connected to the electric motor 9 of the drive for charging through the feed box 10, gear, 11 And the worm gear 12.; IB a kinematic chain, connecting the spindle of the product 8 and the eccentric 7 of the milling head drive, includes a manual gearbox 13 with shiftable gear pairs and a tuning unit 14. The latter is equipped with two drive shafts 15 and 16, connected by a chain gear 17 and rotating | in one direction. On shaft axes 15 and 16, the sets of gears I are rigidly mounted, located f on one of the shafts in order of increasing, as well. in the second order of decreasing their outer diameter. Melsdu driving shafts 15 and 16 is located driven spline shaft 18, connected to the eccentric 7 and carrying axially movable block 19 with a spanner, which can be introduced into the backing with any of the gears, closed: Prisoners on the shafts 16 and 15. Goleke milling connected with the upper threaded end of the rod 5 through the nut 2O, on which is fixed a gear wheel 21, which engages with the cylindrical gear 22. The ice is mounted in a stationary case connected through a bevel gear 23c with the handle 24. The processing of the ends of the teeth of the rear wheel ki m cated on the machine in a continuous, uniformly rotating the spindle 8 and the product agreed with him prefecture reciprocating translational movement of the milling head 2 with the vertical plane. Adjusting the forming movements of the machine consists in setting the stroke of the milling head 2, carried out by adjusting the eccentric 7, and setting the gear ratio between the pin of the product 8 and the eccentric 7. The latter is performed by appropriately changing the gear 13 and engaging the cap gear unit 19 with the required gear wheel shaft 15 or 16. Formula of the invention: Tooth-rounding machine for processing cylindrical wheels with a finger-shaped cutter installed in the movable head which is mounted on rectilinear guides and driven by a cam mechanism kinematically associated with the workpiece spindle, characterized in that, in order to shorten the duration and simplify the setup of the machine, into the kinematic chain connecting the workpiece spindle to the head drive, included two parallels leading in front of; ala, moving along the water side and carrying the gears rigidly fixed on them (; wheels, which are located on one of the shafts in order of increasing, and in the second - in decreasing order Their outer diameter, and between the drive shafts, there is a driven slit shaft, equipped with an axially movable block of the pinion gear, meshed with one of the gears of the drive shafts.
