Description
пользуют конечные выключатели 14 и 15, включе ные в электрическую цепь питани электродвигател станка.limit switches 14 and 15 are used, which are included in the electric supply circuit of the electric motor of the machine.
К внутренним то,рцам обеих частей барабана 5 прикреплены конические зубчатые колеса 16 и 17. В подшипниковой втулке на корпусе устройства свободно установлена коническа шестерн -хвостовик 18 с квадратом или руко ткой на конце.Bevel gears 16 and 17 are attached to the inner, to the ends of both parts of the drum 5. A bevel gear-shank 18 with a square or a handle at the end is loosely mounted on the bearing sleeve on the device body.
На Ш1пинделе 5 на шпонке установлен фланец 19, который посредством зажимов 20 может быть жестко соединен с поворотной лравой частью барабана 5.On the Spindle 5, a key is fitted with a flange 19, which by means of the clamps 20 can be rigidly connected to the turntable part of the drum 5.
На обеих част х барабана 5 имеютс метки 21, 1показываюш,ие при своем совпадении оптимальное расположение этих частей, при котором обеспечиваетс полна симметри винтожелобчатых канавок барабана 5,On both parts of the drum 5 there are marks 21, 1, which, if they coincide, have an optimal arrangement of these parts, which ensures the full symmetry of the curved grooves of drum 5,
Устройство работает следуюш;им образом.The device works in the following way.
Предварительно при помощи -нат жных устройств 8 устран етс провисание тросов 6 и 7. Затем освобождаютс зажимы 20, и ше. стерн -хво-стовик 18 вводитс в полное зацепление с коническими колесами 16 и 17. Вращением вручную шестерни-хвостовика /5 производитс разворот конических колес 16 и 17 и св занных с ними левой и правой частей барабана 5, что и обеспечивает быстрое и равномерное нат жение тросов 6 .и 7. Достигнув нужной степени нат жени тросов, закреплением зажимов 20 фиксируют положение п равой части барабана 5 на шпинделе 3. Если после многократных нат жений тросов метки 21 значительно смест тс относительно друг Друга, то посредством регулировки нат жных устройств 8 их вновь совмещают.With the aid of the holding devices 8, the sagging of the cables 6 and 7 is eliminated. Then the clips 20 and more are released. Stern - hv-stovik 18 is introduced into full engagement with the conical wheels 16 and 17. Manual rotation of the gear-shank / 5 turns the conical wheels 16 and 17 and the left and right parts of the drum 5 associated with them, which ensures fast and uniform tension. cable 6. and 7. Having reached the desired degree of cable tension, fixing the clamps 20 fix the position of the equal part of the drum 5 on the spindle 3. If, after repeated tension of the cables, the mark 21 is significantly displaced relative to each other, then by adjusting the tension set oystv 8 combine them again.
Предлагаема система нат жени тросов устройства позвол ет сократить врем его настройки , ПОВЫСИТЬ производительность труда на операци х нарезани винтовых поверхностей переменного щага и, кроме того, улучшить качество продукции.The proposed cable tensioning system of the device makes it possible to shorten its adjustment time, to ENHANCE the labor productivity in cutting operations of the screw surfaces of the variable schag and, moreover, to improve the product quality.
