Description
Изобретение относитс к области электрофизических методов обработки и, в частности, к станку дл электроэрозионной вырезки непрофилированным электродом-инструментом . Известен станок дл электроэрозионной нырезки, содержащий генератор, подключен ный к электроду-инструменту и детали, копир, устройство дл измерени копировального промежутка, соединенное с регул тором , к которому через усилитель поэключен исполнительный двигатель . Однако регул тор копировального промежутка не обеспечивает высокой точности котировани , так как имеет низкую чувствительность. Цель изобретени - повышение точ ност копировани и исключение износа копира при электроконтакгном копировании . Это достигаетс i-eM, что в предлагаемое устройство введены два управл емых от генератора электронных ключа, один из которых включен последовательно в цепь, состо5Ш1ую из электрода-инструмента , устройства измерени копировального прюмежутка и копира, а второй подключен параллельно устройству измеуюни сопировального промежутка и первому ключу. На чертеже приведена схема предлагаемого устройства, где 1 - токопровоД5пций кстир; 2. - электрод-инструмент; 3 - обрабатываема деталь; 4 - устройство дл измерени копировального njxjмежутка; 5 и 6 - сопротивлени утечки; 7 - генератор; 8 и 9 - электронные кл7О«чи; 1О - цепь управлений ключами. Устройство работает следук цим образом . Устройство 4 вырабатывает сигнал, соответствующий состо нию ксшйГмэЕального промежутка. Этот сигнал через уснлИ. тель поступает на исполнительный двигатель (на чертеже не показан), которьгй или разводит электрод-инструмент и копир прн их замыкании, или сближает их,The invention relates to the field of electrophysical processing methods and, in particular, to a machine for electroerosive cutting with a non-profiled electrode tool. A known machine for EDM piping, comprising a generator connected to the tool electrode and part, a copier, a device for measuring a copy gap, connected to a regulator, to which an actuating motor is connected through an amplifier. However, the controller of the copying gap does not provide high accuracy of quotation, since it has a low sensitivity. The purpose of the invention is to improve the accuracy of copying and to exclude the wear of the copier during electric contact copying. It is achieved by i-eM that two electronic keys controlled from a generator are introduced into the proposed device, one of which is connected in series to a circuit consisting of an electrode tool, a measuring device of a copying curb and a copier, and the second is connected in parallel to the device changing the matching gap and the first the key. The drawing shows the scheme of the proposed device, where 1 is the current circuitry of the device; 2. - electrode tool; 3 - workpiece; 4 is a device for measuring copy njxj spacing; 5 and 6 - leakage resistance; 7 - generator; 8 and 9 - electronic kl7O "Chi; 1O - key management chain. The device works in the following way. The device 4 generates a signal corresponding to the state of the xychmeeal gap. This signal through usNI. The body goes to the executive motor (not shown in the drawing), which either separates the electrode-instrument and the copier to close them, or brings them closer,
