Description

рой св заны с выходами схемы сравнени  и преобразовател  оборотов, а выход преобразовател  код-аналог соединен с генератором .the swarm is connected to the outputs of the comparison circuit and the speed converter, and the code-analog converter output is connected to the generator.

На чертеже представлена блок-схема предлагаемого устройства.The drawing shows a block diagram of the proposed device.

Устройство содепжит преобразователь I вибраций, предварительный усилитель 2, усилитель 3, электронный ключ 4, счетчик 5, схемы 6 совпадени  и интеграторы 7, многовходовой регистратор 8, схему 9 сравнени , дифференцирующее звено 10, релаксационный генератор 11, с;(ему 12 совпадени , дифференцирующее звено 13, преобразователь 14 оборотов, электронный ключ 15, реле-регул тор 16, схему 17 совпадени , счетчик }8, преобразователь код-аналог 9.The device includes a vibration converter I, a preamplifier 2, an amplifier 3, an electronic switch 4, a counter 5, a matching circuit 6 and an integrator 7, a multi-pass recorder 8, a comparison circuit 9, a differentiator 10, a relaxation generator 11, s; (it matches 12, differentiator 13, 14 turn converter, electronic key 15, relay-controller 16, coincidence circuit 17, counter} 8, code-equivalent converter 9.

Работает устройство следующим образом .The device works as follows.

При обработке заготовки режущим инструментом , например фрезой, колебани  регнстрируютс  преобразователем I и преобразуютс  в пилообразное напр жение, которое поступает на предварительный усилитель 2 и уснлитель-ограннчитель 3 и преобразуютс  в пр моугольные импульсы. Последние через ключ 4 подаютс  на вход счетчнка 5, регистрирующего столько импульсов эа оборот сколько зубьев фрезы находилось в зацеплении с заготовкой. .Затем импульсы поступают на схему 6 совпадени . В свою очередь, пр моугольные импульсы с выхода усилител  3 подаютс  на схему 9 сравнеки , после дифференцировани  звеном 10 положительные импульсы идут на запуск генератора It, а отрицательные на схему 12 совпадени . Полученные на выходе генераTOjia пр моугольные импульсы  вл ютс  опорными .дл  схемы 9 сравнени . Длительность опорных им ульсов соответствует критическому износу зубьев фрезы и может быть задана вручную или автоматически в процессе самообучени  устройства с ломощью цепи элементов, состо щей ш схемы 17 совпадени , счетчика 18 и предбразовател  код-аналог 19.When the workpiece is machined with a cutting tool, such as a milling cutter, the oscillations are detected by the transducer I and converted into a sawtooth voltage, which is fed to the preamplifier 2 and the suppressor limiter 3 and converted into rectangular pulses. The latter, via the key 4, are fed to the input of the counter 5, which records so many pulses e turn as many of the cutter teeth were in engagement with the workpiece. Then, the pulses arrive at the coincidence circuit 6. In turn, the rectangular pulses from the output of the amplifier 3 are fed to the circuit 9 sravneki, after differentiation of the link 10 positive pulses go to start the generator It, and the negative to the circuit 12 coincidence. The rectangular pulses obtained at the output of the oscillator are the reference ones for the comparison circuit 9. The duration of the pulses supporting them corresponds to the critical wear of the cutter's teeth and can be set manually or automatically in the process of self-learning of the device with a chain of elements consisting of a matching circuit 17, a counter 18 and a pre-code analog.

Выходной сигнал регистратора 8 и реле-регул тора 6  вл етс  выходным сигналом устройства дл  управлени  процессом резани , а Цифрова  индикаци  р дес тичнбм коде выхода счетчика 5  вл етс  визуальным контролем режущего зуба фрезы, достигшего критического значени  износа.The output signal of the recorder 8 and the relay-controller 6 is the output signal of the device for controlling the cutting process, and the digital indication of the ten-code output code of the counter 5 is the visual control of the milling cutter tooth that has reached the critical wear value.
