Abstract

A drive element (1) is used for displacing a tool carrier (2), on which there is fastened a workpiece (5) which is machined by a grinding wheel (4). The adjustment of the drive element (1) is controlled via a switching device (7) which is connected to a first sensor (9) and to a second sensor (3). The first sensor (9) is used for establishing the end of the contact of the tool (4) with the workpiece (5). The second sensor (3) is used for establishing the beginning of the contact of the tool (4) with the workpiece (5). The device can be used for controlling the hobbing movements in tooth flank grinding machines which operate with a taper disc. <IMAGE>

Description

ти соединены с входами  чеек ИЛИ через переключатель 11 чистового режима. Катушка 9 подключаетс  к усилителю через тот же переключатель 11 чистового режима.These are connected to the inputs of the cells OR via the switch 11 of the finishing mode. The coil 9 is connected to the amplifier through the same switch 11 of the finishing mode.

Работает устройство следующим образом .The device works as follows.

Перед началом работы ключи 3,3.1 подсоедин ют конденсаторы 4,4.1 один к нулевой шипе, другой - к источнику питани . Этим обеспечиваетс  исходное состо ние элементов пам ти. При относительном перемещении инструмента и детали , когда круг на черновых режимах не касаетс  шлифуемого издели , сигнал на датчике положени  измен етс  по пилообразному закону. Однако в блок пам ти информаци  не поступает, так как ключи 3, 3.1 остаютс  разомк-нутыми. Если круг касаетс  издели , то сигнал с датчика 10 контакта инструмента с деталью поступает на переключатель 8, тем самым включа  рабочую подачу и подключа  элементы пам ти к датчику положени . Незар женный конденсатор 4 зар жаетс  до максимального значени  за один или несколько проходов. В то же врем  конденсатор 4.1 зар жаетс  до минимального значени  сигнала датчика положени . Эти максимальное и минимальное значени  сигналов датчика положени  сохран ютс  в пам ти в виде напр жени  и означают крайние точки наличи  шлифовани  дл  данной детали . На чистовых проходах происходит перебрасывание переключател  11 в другое положение, тем самым подключение элементов пам ти к переключателю 8. При относительном перемещении инструмента и детали сигнал с датчика положени  поступает на второй вход пороговых элементовBefore starting the operation, the keys 3.3.1 connect the capacitors 4.4.1 one to the zero stud, the other to the power supply. This provides the initial state of the memory elements. With a relative movement of the tool and part, when the circle in draft modes does not touch the product being ground, the signal on the position sensor changes according to the sawtooth law. However, information is not received in the memory block, since the keys 3, 3.1 remain open. If the circle is in contact with the product, the signal from the sensor 10 of the tool’s contact with the part is fed to the switch 8, thereby turning on the working feed and connecting the memory elements to the position sensor. Uncharged capacitor 4 is charged to a maximum value in one or more passes. At the same time, capacitor 4.1 is charged to the minimum value of the position sensor signal. These maximum and minimum values of the position sensor signals are stored in memory in the form of voltage and indicate the extreme points of the presence of grinding for a given part. On the finishing passes, the switch 11 is moved to another position, thereby connecting the memory elements to the switch 8. With relative movement of the tool and part, the signal from the position sensor is fed to the second input of the threshold elements

5, 5.1, на первые входы которых поступают сигналы, хран щиес  в элементах пам ти. При совпадении амплитуд этих сигналов вырабатываетс  сигнал переключени , который поступает на переключатель 8 через5, 5.1, the first inputs of which receive signals stored in the memory elements. When the amplitudes of these signals coincide, a switching signal is produced, which is fed to switch 8 through

одну из  чеек ИЛИ.one of the cells OR.
