Abstract

Изобретение относитс к машиностроению и может быть использовано дл транспортировки деталей при сборочных работах. Цель изобретени - расширение кинематических возможностей путем изменени угла поворота ведомого вала. Указанна цель достигаетс за счет возможности преобразовани равномерного вращательного движени в прерывистое вращение ведомого вала с регулируемым циклом. Ведущий вал 3 вращает зубчатые колеса 7- 10 и одновременно эксцентрик 6, который периодически взаимодействует с роликом 13. При этом т га 12 при помощи храповиков 15 поворачивает храповое колесо 11 на угол, равный шагу его зубьев. На этот же угол поворачиваетс и ведомый вал 4, перемеща исполнительный механизм по заданной программе. 2 ил.The invention relates to mechanical engineering and can be used to transport parts during assembly work. The purpose of the invention is to expand the kinematic capabilities by changing the angle of rotation of the driven shaft. This goal is achieved due to the possibility of converting a uniform rotational movement into an intermittent rotation of the driven shaft with an adjustable cycle. The drive shaft 3 rotates the gear wheels 7-10 and at the same time the eccentric 6, which periodically interacts with the roller 13. At the same time, the tractor 12 turns the ratchet wheel 11 by an angle equal to the pitch of its teeth. At the same angle, the output shaft 4 is rotated, moving the actuator according to a predetermined program. 2 Il.

Claims

Claim

A device for converting uniform rotation to intermittent, comprising a housing, a drive shaft with an eccentric installed in it, a driven shaft with a ratchet wheel, a gear transmission connecting the shafts to each other, a link with ratchets interacting with the ratchet wheel mounted to rotate on the driven shaft, and with a roller spring-loaded to the eccentric and the link, characterized in that, in order to expand the kinematic capabilities by changing the angle of rotation, it is equipped with a lever mounted in the housing with a roller on it about the free end mounted on the wings of the carrier, pivotally connected to the traction, and fingers designed to interact with the lever roller and mounted on the end of one of the gear wheels, which is freely mounted on the driven shaft.
