Description

Известны способы обработки глобоидных черв ков при взаимном огибании заготовки производ одей поверхностью дискового инструмента . Оси заготовки и инструмента взаимно наклонены, и инструменту сообщают планетарное движение.Known methods of processing globoid worms with the mutual rounding of the workpiece produce the surface of the disk tool. The axes of the workpiece and the tool are mutually inclined, and the tool is reported to have a planetary motion.
Глобоидные черв ки, полученные известными способами, по форме и чистоте поверхности отличаютс от теоретических (эталонных) глобоидных черв ков.Globoid worms obtained by known methods are different in shape and surface finish from theoretical (reference) globoid worms.
Предложенный способ позволит максимально приблизить получаемые параметры обрабатываемого черв ка к параметрам расчетного.The proposed method will allow as close as possible the obtained parameters of the processed worm to the calculated parameters.
Дл этого планетарное движение инструменту сообщают в плоскости, наклоненной к оси заготовки, в которой и располагают ось его вращени .For this, the planetary movement of the tool is reported in a plane inclined to the axis of the workpiece, in which the axis of its rotation is located.
Па чертеже показана принципиальна схема обработки витков глобоидиого черв ка по предлагаемому способу.Pa the drawing shows a schematic diagram of the processing of coils of a globoid worm according to the proposed method.
Заготовку 1 обрабатывают дисковым инструментом 2, установленным на вращающемс столе 3 станка. Инструмент 2, кроме вращени относительно оси I-I стола 3, вращаетс относительно собственной оси II-II.The blank 1 is machined with a disc tool 2 mounted on a rotating table 3 of the machine. Tool 2, besides rotating about axis I-I of table 3, rotates about its own axis II-II.
Ось III-III обрабатываемой заготовки 1 наклонена к оси I-I вращени стола 3 на угол.The axis III-III of the workpiece 1 is inclined to the axis I-I of rotation of the table 3 by an angle.
равный углу подъема внтка черв ка в горловине .equal to the elevation angle of the screw of the screw in the neck.
Угловые скорости вращени заготовки и стола св заны станочным передаточным отнонлением I, которое определ ют расчетом по заданной модификации черв ка. Оно .может быть равным или отличающимс от передаточного отнощени глобопдпой передачи.The angular velocities of rotation of the workpiece and the table are related by machine transfer otnonenie I, which is determined by calculation for a given modification of the screw. It can be equal to or different from the gear ratio of global transmission.
Инструмент, враща сь относительно собственной оси II-П и одновременно относительно оси I-I стола 3 в пределах угла обхвата колеса черв ком, производит на вращающейс заготовке черв ка формирование боковой поверхности витков за один проход.The tool, which rotates about its own axis II-P and at the same time relative to the axis I-I of the table 3 within the wrap angle of the wheel, produces a side surface of the turns in a single pass on the rotating billet of the screw.
Предмет изобретени Subject invention
Способ обработки глобоидных черв ков при огибании заготовки производ щей поверхностью дискового инструмента, совершающего планетарное дв1 жение, причем оси заготовки и инструмента наклонены, о т л и ч а ю щ и и с тем, что, с целью получени формы поверхности глобоидного черв ка, максимально приглижающейс к форме поверхности расчетного глобоидного черв ка, ось вращени инструмента располагают в плоскости, наклоненной к оси заготовки, и планетарное движение инструменту сообщают в этой же плоскости.The method of processing globoid screws when the workpiece bends around the production surface of a disk tool making a planetary double, with the axes of the workpiece and tool tilted so that, in order to obtain the shape of the surface of the globoid screw, As close as possible to the shape of the surface of the calculated globoid screw, the axis of rotation of the tool is placed in a plane inclined to the axis of the workpiece, and the planetary motion of the tool is reported in the same plane.
