Изобретение относитс к машиностроению и может быть использовано в металлорежущих станках.The invention relates to mechanical engineering and can be used in machine tools.
Известный механизм содержит рейку, зубчатые колеса, взаимодействующие с рейкой, и тормозную муфту, воздействующую на одно из колес.The known mechanism includes a rail, gears interacting with the rail, and a brake clutch acting on one of the wheels.
Однако в известном устройстве при останове возникают большие усили в паре шестерн - рейка, что приводит к быстрому их износу .However, in the known device when stopping large forces occur in a pair of gear - rail, which leads to their rapid wear.
В предлагаемом устройстве уменьшение износа рейки и зубчатых колес, а также увеличение точности фиксировани достигаетс тем, что механизм снабжен самотормоз щей черв чной парой, черв чное колесо которой установлено соооно одному из колес и жестко св зано с ним, а тормозна муфта взаимодействует с другим зубчатым колесом.In the proposed device, reducing wear of the slats and gears, as well as increasing the fixing accuracy, is achieved by the fact that the mechanism is equipped with a self-braking worm gear pair, the worm wheel of which is mounted to one of the wheels and rigidly connected with it wheel.
На чертеже приведена кинематическа схема механизма.The drawing shows the kinematic scheme of the mechanism.
Механизм содержит рейку 1, зубчатые колеса 2, 3, взаимодействующие с рейкой 1, тормозную муфту 4, воздействующую на зубчатое колесо 3, самотормоз щую черв чную пару с черв ком 5 и черв чным колесом 6, соосным колесу 2 и жестко св занным с ним.The mechanism contains rail 1, gears 2, 3 interacting with rail 1, brake coupling 4 acting on the gear 3, self-braking a worm pair with a screw 5 and a worm gear 6, coaxially with wheel 2 and rigidly connected with it .
Механизм работает следующим образом.The mechanism works as follows.
При торможении узла одновременно включаетс тормозна муфта 4 и отключаетс привод черв ка 5. В результате в механизме возникают силы, направленные в противоположные стороны, благодар наличию самотормоз щей черв чной пары, и создаютс расклинивающие усили , сохран ющиес после полной остановки узла.When the assembly is braked, the brake clutch 4 is simultaneously turned on and the screw drive 5 is turned off. As a result, forces are directed in opposite directions, due to the presence of a self-braking screw pair, and wedging forces are created that remain after the node has completely stopped.
Предмет изобретени Subject invention
Механизм точного останова и фиксировани подвижного узла металлорежущего станка, содержащий рейку, зубчатые колеса, взаимодействующие с рейкой, и тормозную муфту, воздействующую на одно из колес, отличающийс тем, что, с целью увеличени точности фиксировани и уменьшени износа рейки и зубчатых колес, механизм снабжен самотормоз щей черв чной парой, черв чное колесо которой установлено соосно одному из колес и жестко св зано с ним, а тормозна муфта взаимодействует с другим зубчатым колесом.A mechanism for accurately stopping and fixing the movable assembly of the cutting machine, comprising a rail, gears interacting with the rail, and a brake clutch acting on one of the wheels, characterized in that, in order to increase the fixing accuracy and reduce wear of the rail and gears, a self-braking worm gear pair, the worm wheel of which is mounted coaxially with one of the wheels and rigidly connected with it, and the brake clutch interacts with the other gear wheel.
