Abstract

Изобретение относитс к машиностроению и может быть использовано в универсальных зубофрезерныхстанках при единичном и мелкосерийном производстве зубчатых колес. Цель изобретени - упрощение конструкции за счет сокращени элементов кинематической цепи. При работе станка методом обката механизм единичного делени (т.е. поворота стола на заданный угол) не используетс . При работе станка методом единичного делени , т.е. когда обработка осуществл етс дисковой или пальцевой фрезой, гидроцилиндр 11 включает кулачковую муфту 7, рассоедин валы 5 и 6. После прорезани очередной впадины изделие (стол) поворачивают на 1/z путем включени от гидроцилиндра 11 муфты 7, а фиксатор 10 посредством гидроцилиндра 12 освобождает делительный диск 8 от соединени с корпусом. За период отработки механизма поворота стола на заданный угол валы 5 и 6 работают как единый целый вал, передава периодическое вращение от привода 3 главного движени на гитару делени и далее на изделие. 1 з.п.ф-лы, 2 ил. СП СThe invention relates to mechanical engineering and can be used in universal gear milling machines for single and small-batch production of gears. The purpose of the invention is to simplify the design by reducing the elements of the kinematic chain. When the machine is operated by the rolling method, the unit division mechanism (i.e., turning the table at a given angle) is not used. When the machine is operated by the single division method, i.e. when machining is performed by a disk or finger cutter, the hydraulic cylinder 11 turns on the cam coupling 7, disconnects the shafts 5 and 6. After cutting the next depression, the product (table) is turned 1 / z by switching on from the hydraulic cylinder 11 of the coupling 7, and the lock 10 by means of the hydraulic cylinder 12 releases separator disc 8 from connection with housing. During the period of working out the table rotation mechanism at a given angle, the shafts 5 and 6 work as a single whole shaft, transmitting a periodic rotation from the drive 3 of the main movement to the dividing guitar and further to the product. 1 hp ff, 2 ill.
