Description
Изобретение . к антоматгшеским -регул торам, поддерживающим заданное 1аеето иие от резака до поверхности издели в маишиах дл газокислородной резки металлов.The invention. to dental controllers that support the specified 1aetoe from the cutter to the surface of the product in machines for the gas-oxygen cutting of metals.
Известные регул торы такого рода, содержаигие епЯзаиныГг с резаком электрический датчик, показани которого завис т от положени ,резака, схему сравнени показаний датчика с опориым напр жением, усилитель посто нного тока и исполнительный механизм дл перемеП1ени резака по высоте, пе обеспечивают необходимой точности регулировани .Known regulators of this kind, containing an electric sensor with a cutter, an electrical sensor, the readings of which depend on the position of the cutter, a comparison circuit of the sensor with voltage reference, a DC amplifier and an actuator for changing the cutter height, do not provide the necessary control accuracy.
Дл устранени указанного недостатка предлагаетс датчик выполн ть в виде плоской и {дуктивпой катушки, составл юи1ей часть колебательного контура, питаемого током высокой частоты.To eliminate this drawback, it is proposed to perform the sensor in the form of a flat and {ductable coil, which is a part of the oscillatory circuit fed by a high frequency current.
На чертеже представ.тена принципиалыга электрическа схема предлагаемого регул тора.The drawing shows the principle of the electrical circuit of the proposed controller.
Генератор высокой частоты / подключен к колебательному контуру , еосто щему из конденсатора 2 и плоской ипдуктивной катушки о. св занной с резаком 4. Индуктивность катушки 3 зависит от рассто ни между резаком 4 и разрезаемым изделием 5. Синусо)1дальное напр жение с линейного сопротивлени 6 через детектор / подаетс на сетку ламиы S. С делител напр жени 9 опорное напр жение подаегс на сетку лампы 10. Лампы (S и 10 вместе с сопротивлени ми // и 12 образуют мостовую схему, к точкам 13 и 14 которой подаетс посто иное напр жение, а к точкам 5 и 16 подключаетс обмотка управлени 17 электромашинного усилител 18, питающего исполнительный двигатель 19, осуществл юший перемещение резака ио вертикали.A high-frequency generator / is connected to an oscillatory circuit consisting of a capacitor 2 and a flat impedance coil. connected to the cutter 4. The inductance of the coil 3 depends on the distance between the cutter 4 and the product being cut 5. Sine) 1dal voltage from the line resistance 6 through the detector / is fed to the grid of Lamia S. lamps 10. Lamps (S and 10 together with resistors // and 12 form a bridge circuit, to the points 13 and 14 of which a constant voltage is applied, and to points 5 and 16 the control winding 17 of the electromachine 18, supplying the executive motor 19 made the most move Ezaki uo vertically.
Параметры схемы подбираютс так, чтобы при заданном рассто нии резака от издели сигнал, поступающий на сетку лампы А , был раThe parameters of the circuit are selected so that at a given distance of the cutter from the product, the signal arriving at the grid of the lamp A is equal to
