На чертеже представлена структурная электрическая схема предложенного устройства.The drawing shows a structural electrical diagram of the proposed device.

Устройство для автоматического установления перестраиваемого органа в заданное положение содержит реле 1, 2, 3 (1—1, 1.-2, 1-3 - контакты реле 1; 2-1,A device for automatically setting the tunable organ to a predetermined position contains relay 1, 2, 3 (1-1, 1.-2, 1-3 - relay contacts 1; 2-1,

2- 2, 2-3 - контакты реле 2; 3-1, 3-2,2-2, 2-3 - relay contacts 2; 3-1, 3-2,

3- 3 - контакты реле 3), концевые выключатели 4-1, 4-2, 4-3 ... 4-п; переключатель 5 на η положений; переключатель 6 на η положений; электродвигатель 7; редуктор 8; перестраиваемый орган 9 (9-1, 9-2, ... 9- ц - фиксируемые положения перестраиваемого органа).3- 3 - relay contacts 3), limit switches 4-1, 4-2, 4-3 ... 4-p; switch 5 to η positions; switch 6 to η positions; electric motor 7; gearbox 8; tunable organ 9 (9-1, 9-2, ... 9- c - fixed positions of the tunable organ).

Устройство работает следующим образом.The device operates as follows.

Пусть, например, исходным положением перестраиваемого органа 9 является положение, определяемое разомкнувшимся контактом концевого выключателя 4-3. Тогда разомкнувшиеся контакты концевых выключателей 4—2, 4—4, замкнувшийся контакт 3—1 реле 3 и разомкнувшийся контакт 2-1 реле 2 образуют цепь питания обмотки реле 1, а разомкнувшиеся контакты концевых выключателей 4-4 ...Let, for example, the initial position of the tunable organ 9 is the position determined by the open contact of the limit switch 4-3. Then the open contacts of the limit switches 4–2, 4–4, the closed contact 3–1 of the relay 3 and the open contact 2–1 of the relay 2 form the power supply circuit of the coil of the relay 1, and the open contacts of the limit switch 4–4 ...

4- гх и контакт 1—1 реле 1 - цепь питания обмотки реле 2.4- GC and pin 1-1 of relay 1 - power supply circuit of the coil of relay 2.

Если переключателями 5 и 6 задать новое положение перестраеваемого органа 9, порядок которого ниже исходного, например, положение, определяемое контактом концевого выключателем 4-1, то через соответствующие контакты этих переключателей напряжение подается на об— ,мотку реле 3 и после замыкания контакта 3-1 релеЗ на обмотку реле'1. При этом ι ·χ· замыкаются контакты 3-2, 3-3, реле 3, включающие электродвигатель 7, и 1-2, 1-3 реле 1, обеспечивающие вращение электродвигателя 7 и перестройку органа 9 от исходного положения по нисходящей в сторону заданного положения. Когда перестраиваемый орган 9 отработает заданное положение, то сработает контакт концевого выключателя 4—1, и размыкая его, отключит реле 3. В результате этого разомкнутся контакты 3-1, отключающий реле 1, 3-2 и 3-3, отключающие электродвигатель 7, и перестраиваемый орган 9 остановится в заданном положении.If the switches 5 and 6 set the new position of the tunable body 9, the order of which is lower than the initial one, for example, the position determined by the contact of the limit switch 4-1, then through the corresponding contacts of these switches the voltage is applied to the coil, relay 3, and after closing the contact 3- 1 relay 3 per relay coil'1. In this case, ι · χ · closes the contacts 3-2, 3-3, relay 3, including the electric motor 7, and 1-2, 1-3 of the relay 1, providing rotation of the electric motor 7 and the restructuring of the organ 9 from the initial position downward to the specified provisions. When the tunable body 9 works out the preset position, the contact of the limit switch 4-1 will work, and opening it will turn off the relay 3. As a result, contacts 3-1 will open, disconnecting the relay 1, 3-2 and 3-3, disconnecting the motor 7, and tunable body 9 will stop at a predetermined position.

Если же переключателями 5 и 6 задать: положение перестраиваемого органа 9, порядок которого выше исходного, например, положение, определяемое контактом концевого выключателя 4-4, то через соответствующие контакты переключателей 5, 6 напряжение подается на обмотки реле 3 и 2. При этом замыкаются контакты 3-2, 3-3, включающие электродвигатель 7, и 2-2, 2-3, обеспечивающие вращение электродвигателя 7 и перестройку органа 9 от исходного положения по восходящей в сторону заданного положения. Когда перестраиваемый орган 9 отработает заданное положение, то разомкнется контакт концевого выключателя 4-4 и отключит реле 3 и 2. В результате этого разомкнутся контакты 3-2, 3-3 и 2-2, 2-3, отключающие электродвигатель 7, и перестраиваемый юрган 9 остановится в заданном положении,If, by switches 5 and 6, you set: the position of the tunable body 9, the order of which is higher than the initial one, for example, the position determined by the contact of the limit switch 4-4, then through the corresponding contacts of the switches 5, 6, the voltage is supplied to the relay windings 3 and 2. In this case, they close contacts 3-2, 3-3, including the electric motor 7, and 2-2, 2-3, providing rotation of the electric motor 7 and the rebuilding of the organ 9 from its initial position in ascending direction of the specified position. When the tunable body 9 fulfills a predetermined position, the contact of the limit switch 4-4 will open and disconnect the relay 3 and 2. As a result, the contacts 3-2, 3-3 and 2-2, 2-3, disconnecting the motor 7, and the tunable yurgan 9 will stop in the set position,

В случае, если исходное положение перестраиваемого органа 9 расположено между двумя разрешенными положениями, например, между положениями, определяемыми контактами концевых выключателейIf the initial position of the tunable body 9 is located between two permitted positions, for example, between the positions determined by the contacts of the limit switches

4-3 и 4-4, то при установке перестраиваемого органа 9, например, в положение определяемое концевым Выключателем 4—1, через переключатели 5 и 6 напряжение подается на обмотки реле 3 и 2, Контак- 5 ты 3-2, 3-3 и 2-2, 2-3 замкнутся и включится электродвигатель 7. В результате этого перестройка органа 9 будет происходить в сторону, обратную от заданного положения. Однако, когда орган 9 от-1° работает ближайшее разрешенное положение, т.е. в данном случае, положение определяемое концевым выключателем 4-4,4-3 and 4-4, then when the tunable organ 9 is installed, for example, in the position determined by the limit switch 4-1, voltage is supplied through the switches 5 and 6 to the relay windings 3 and 2, Contacts 5–2, 3–2, 3– 3 and 2-2, 2-3 will be closed and the electric motor 7 will turn on. As a result of this, the reorganization of the organ 9 will occur in the direction opposite to the given position. However, when the organ 9 from -1 ° works the closest permitted position, i.e. in this case, the position determined by the limit switch 4-4,

I то последний сработает и, размыкая свой контакт, отключит реле 2. Реле 3 оста-* ^,5нется включенным, т.е. контакт 3-1 замкнутым, тогда сработает реле 1, замкнутся контакты 1-2 и 1-3 и изменится направление вращения оси электродвигателя 7 и, следовательно, орган 9 станет пере- ²⁰страиваться в сторону заданного положения до тех пор, пока не сработает концевой выключатель 4-1, определяющий это положение.I then the latter will work and, opening its contact, will turn off relay 2. Relay 3 remains * ^{, 5} remains on, i.e. 3-1 closed contact, while the relay 1 will work, closed contacts 1-2 and 1-3, and change the motor direction of rotation axis 7 and, therefore, the body 9 will be transferred in the direction ²⁰ tune in to a predetermined position until the end does not work switch 4-1, determining this position.

Технико—экономическая эффективность устройства для автоматического установления перестраиваемого органа в заданное положение заключается в повышении точности отработки заданных положений.The technical and economic efficiency of the device for automatically setting a tunable organ to a predetermined position consists in increasing the accuracy of working out the predetermined positions.

The drawing shows a structural electrical circuit of the proposed device. A device for automatically establishing a tunable organ in a predetermined position contains a relay 1, 2, 3 (1-1, 1-2, 1-3 - contacts of relay 1; 2-1, 2-2, 2-3 - contacts of relay 2; 3- 1, 3-2, 3-3 - relay contacts 3), limit switches 4-1, 4-2, 4-3 ... 4-п; switch 5 on n positions; switch 6 in n positions; electric motor 7; gearbox 8; tunable gun 9 (9-1, 9-2, ... 9-g - fixed positions of the tunable organ). The device works as follows.

If the switches 5 and 6 set the new position of the tunable organ 9, then which dock is lower than the original, for example, the position, o limited by the contact of the limit switch 4-1, then through the corresponding contacts of these switches, the voltage is applied to the winding of the relay 3 and after closing the contact 3-1 of the relay to the winding of relay1.
