Изобретение относитс к области станкостроени и может быть использовано в металлорежущих станках.The invention relates to the field of machine tools and can be used in machine tools.
Известен способ определени момента касани инструмента с деталью, осиованный на фиксировании изменени амплитуды колебаnmi , возникаюниих в момент касани ииструмента с деталью.There is a known method for determining the moment of contact of a tool with a part, which is based on fixing the change in the amplitude of oscillations that occur at the moment of touching the tool with the part.
Цель предлагаемого способа - повышение надежности выделени сигнала.The purpose of the proposed method is to increase the reliability of signal extraction.
Дл этого по предлагаемому способу в узлах станка возбуждают колебани с частотой , лежан1ей вне спектров частот колебаний станка, и настраивают чувствительный элемент на данную частоту.To do this, according to the proposed method, oscillations are excited at the machine nodes with a frequency that lies outside the spectra of the machine oscillation frequencies, and the sensitive element is tuned to this frequency.
На чертеже изображено устройство, реализующее предлагаемый способ.The drawing shows a device that implements the proposed method.
На станке 1 смонтирован маломощный генератор 2 механических колебаний и чувствительный элемент 3. Инструментом 4, касаюншмс детали 5 вл етс абразивный круг. Чувствительный элемент 3 св зан через усилитель 6 с командоаппаратом 7.On the machine 1, a low-power mechanical vibration generator 2 and a sensing element 3 are mounted. The tool 4 that touches the part 5 is an abrasive wheel. The sensing element 3 is connected via an amplifier 6 with a command device 7.
Устройство работает следующим образом.The device works as follows.
Генератор 2 механических колебаний вибрирует с частотой, лежагцей вне снектров часТОТ колебаний станка 1, возбун дает колебани в узлах станка 1. Чувствительный элемент 3 настроен на частоту генератора 2, т.е. фиксирует только колебани , возбуждаемые им. В момент касани инструмента 4 детали 5 упруга система станка 1 замыкаетс , вызыва изменение амплитуды вынужденных колебаний станка 1, вызванных генератором 2 механических колебаний. Чувствительный элемент 3 фиксирует изменение амплитуды вынужденных колебаний и через усилите.ть 6 дает сигнал иа командоаппарат 7, управл ющи1 переключением ускоренного перемещени инструмента 5 на рабочее.The oscillator 2 of mechanical oscillations vibrates with a frequency that is outside the clock of the oscillations of the machine 1, the oscillator gives oscillations in the nodes of the machine 1. The sensing element 3 is tuned to the frequency of the generator 2, i.e. captures only the vibrations excited by it. When the tool 4 touches the parts 5, the elastic system of the machine 1 closes, causing a change in the amplitude of the forced oscillations of the machine 1 caused by the generator 2 of the mechanical oscillations. The sensing element 3 detects the change in the amplitude of the forced oscillations and, through amplification 6, gives a signal to the controller 7, which controls the switching of the accelerated movement of the tool 5 to the working one.
