Description

Известны многоценные нутевые выключатели , содержащие несколько коммутационных элеменов и приводное устройство, выполненное в виде двух полых подпружиненных ползунов , скольз ще установленных на четырех направл ющих штыр х и жестко соединенных с Т-образным толкателем, а на ползунах установлены продольные кулачки, зафиксированные в определенных местах упорными винтами . Однако привод таких выключателей сложен по своей конструкции и петехнологичен. Например, кулачки можно изготавливать только фрезерованием. В торцах ползунов необходимо нросверлнвать глухие отверсти  под антифрикционные втулки и направл ющие штыри. Узел Т-образного толкател  собирают путем расклепывани  собственно толкател  в перекладине. Дл  обеспечени  регулировани  кулачков должна соблюдатьс  строга  параллельность направл ющих штырей и обхватывающих их ползунов. При несоблюдении этого требовани  происходит заклинивание кулачков при перемещении и регулировка их становитс  нрактически невозможной.Multiple valued nut switches are known that contain several switching elements and a drive device made in the form of two hollow spring-loaded sliders slidably mounted on four guide pins and rigidly connected to a T-shaped push rod, and longitudinal cams fixed in certain places are mounted on sliders hard screws. However, the drive of such switches is complicated in its design and petechnological. For example, cams can be made only by milling. At the ends of the slide blocks, blind holes must be drilled for antifriction sleeves and guide pins. The T-pusher assembly is assembled by ripping the pusher itself in the crossbar. To ensure that the cams are adjusted, the rigorous parallelism of the guide pins and the sliders that encircle them must be respected. If this requirement is not observed, the jams jam when moving, and their adjustment becomes practically impossible.

Дл  упрощени  конструкции, повышени  ее технологичности и обеспечени  удобства регулировани  в предлагаемом выключателе кулачки выполнены в виде скобы с двум  отверсти ми , диалгетр которых соответствует поперечному сечению толкател  приводного устройства , на котором установлены кулачки.To simplify the design, improve its manufacturability and provide ease of adjustment, in the proposed switch, the cams are made in the form of a bracket with two openings, the diageter of which corresponds to the cross section of the pusher of the drive device on which the cams are mounted.

Па чертеже показан описываемый выключатель .Pa drawing shows the described switch.

В корпусе 1 выключател  установлены коммутационные элементы 2. Приводное устройство выполнено в виде толкател  3, направление хода которого нерпендикул рно направлению движени  толкателей коммутационных элементов 2. Па толкателе 3 закреплены с возможностью продольного перемещени  кулачки 4, выполненные в виде штампованной скобы с отверсти ми, надетой на толкатель и закрепленной на нем винтом 5 и двум  накладками 6, одна из которых нмеет резьбовое отверстие. С одной стороны толкател  жесткоIn the case 1 of the switch, the switching elements 2 are installed. The drive device is made in the form of a pusher 3, the direction of travel of which is opposite to the direction of movement of the pushers of the switching elements 2. Pa of the pusher 3 are fixed with the possibility of longitudinal movement of the cams 4, made in the form of a pressed bracket with holes worn on the pusher and fixed on it with a screw 5 and two plates 6, one of which has a threaded hole. On the one hand pushing hard

закреплена скоба 7. В отверсти х скобы 7 установлены антифрикционные втулки 8, в которые пропущены жестко закрепленные на корнусе направл ющие штыри 9 с надетыми на них возвратными пружинами 10. С другойthe bracket 7 is fixed. In the holes of the bracket 7, there are anti-friction sleeves 8, in which the guide pins 9 which are rigidly fixed to the Cornus, with the springs attached to them 10, are passed through.

Ход толкател  в пр мом направленнн ограничивает скоба 7, упирающа с  в корпус, а в обратном направлении -The side of the pusher guide is an antifriction sleeve 11 rigidly mounted in the housing. The pusher travel in the forward direction limits the bracket 7, which abuts against the housing, and in the opposite direction -

In order to protect the switch from the external environment (- dust, moisture, etc.), the pusher is sealed with a rubber cuff 13.
