Устройство также содержит концевые выключатели 36 и 37, реле 38-40,The device also contains limit switches 36 and 37, relays 38-40,
имитатор 41 звука сварочной дуги, генератор 42 секундных импульсов, кнопку 43, усилитель 44 мощности, динамик 43, имитатор 46 звука короткого замыкани .a welding arc sound simulator 41, a 42 second pulse generator, a button 43, a power amplifier 44, a speaker 43, a short circuit sound simulator 46.
Тренажер работает следующим образом .The simulator works as follows.
Тумблером 31 тренажер включают в сеть. При нажатии кнопки 43, расположенной на руко тке имитатора 11 сварочной горелки, -получают питание и загораютс электролампы 10 и 12 на торцах имитатора 2 присадка и имитатора 3 сварочного электрода, одновременно поступает питание на блок 3 управлени . При наведении двух потоков от электроламп 10 и 12 через каналы 14 и 13 на фотодиод 16 имитатора 4 сварочной ванны на вход блока 3 управлени поступает сигнал. По каналам св зи с вихода блока 3 управлени управл ющий сигнал поступает на привод 6 перемещени имитатора 4 сварочной ванны, счетчик 7 времени выполнени упражнени , на электролампы 17 подсветки и реле 38, контакты 39 и 40 которого включают соответственно электролампу 33 и имитатор 41 звука сварочной дуги.Tumbler 31 simulator included in the network. When the button 43 located on the handle of the simulator 11 of the welding torch is pressed, power is obtained and the electric lamps 10 and 12 light up on the ends of the simulator 2 additive and the simulator 3 of the welding electrode, and power is simultaneously supplied to the control unit 3. When two fluxes from the electrolamps 10 and 12 are directed through channels 14 and 13 to the photodiode 16 of the simulator 4 of the weld pool, a signal arrives at the input of the control unit 3. The communication signal from the control unit control input 3 is fed to the actuator 6 for moving the weld pool simulator 4, exercise time counter 7, for the backlight lamps 17 and the relay 38, contacts 39 and 40 of which include the lamp 33 and the sound simulator 41, respectively. arc.
В результате начинает перемещатьс по.ходовому винту 22 имитатор 4 сварочной ванны, начинаетс отсчет времени выполнени упражнени счетчиком 7 и будет высвечена матова поверхность 24 и участки 26 имитатора 4 сварочной ванны. В имитатор 41 образуетс сигнал, который через усилитель 44 мощности воспроизводит динамиком 45 звук, аналогичный звуку сварочной дуги. Обучаемый должен совмещать световые потоки электроламп 10 и 12 имитаторов 2 и 3 присадка и электрода поддержани неизменными углы oi и И и рассто ние до поверхности имитатора 4 сварочной ванны, ориентиру сь относительно матовой поверхности 24 и участков 26, обозначающих границы изображени сварочной ванны.As a result, the simulator 4 of the weld pool begins to move to the travel screw 22, the exercise time begins to begin with the counter 7, and the matte surface 24 and areas 26 of the weld pool simulator 4 will be highlighted. In simulator 41, a signal is generated which, through power amplifier 44, reproduces by speaker 45 a sound similar to that of a welding arc. The learner must combine the light fluxes of the electrolamps 10 and 12 of the simulators 2 and 3 of the additive and the electrode to keep the angles oi and I and the distance to the surface of the weld pool simulator 4 unchanged, relative to the matte surface 24 and the sections 26 that mark the boundaries of the weld pool image.
При смещении одного или обоих световых потоков относительно каналов 14 и 15, изменении углов oi и р или удалении имитаторов 2 и 3 присадка и электрода на величину, превышающую допустимую, включаетс привод 6 перемещени имитатора 4 сварочной ванны, включаютс счетчики 8 и 9 количестваWhen one or both of the light fluxs are displaced relative to channels 14 and 15, the angles oi and p are changed, or the additive and electrode simulators 2 and 3 are removed by an amount exceeding the allowable, the movement 6 of the weld pool simulator 4 is turned on, the counters 8 and 9 are turned on

В момент совмещени световых -потоков на фотодиоде 16 снова включаютс привод 6, имитаторы 35 и 41, выключаютс счетчики 8 и 9, цифровой индикатор 30 фиксирует продолжитель- ность ошибки.At the moment of combining the light fluxes on the photodiode 16, the actuator 6 is turned on again, simulators 35 and 41, counters 8 and 9 are turned off, digital indicator 30 fixes the duration of the error.
При касании имитатора 18 имитаторами 2 и 3 в имитаторе 46 образуетс сигнал, который через усилитель 44 мощности воспроизводит динамиком 45 звук,, аналогичный звуку короткого замыкани .When the simulator 18 is touched by simulators 2 and 3 in the simulator 46, a signal is generated which, through the power amplifier 44, reproduces the speaker 45, a sound similar to a short circuit sound.
При достижении имитатором 4 крайнего положени концевой выключательWhen the simulator 4 reaches the limit position
36 или 37 выключает привод 6 и счетчик 7, электролампу 35 и динамик 45.36 or 37 turns off the drive 6 and the counter 7, the light bulb 35 and the speaker 45.
Таким образом, на цифровых индикаторах 28-30 зафиксированы соответственно врем , затраченное на выполнение упражнени , количество ошибок, допущенных обучающимс , и суммарное врем этих ошибок.Thus, on the digital indicators 28-30, the time taken to complete the exercise, the number of errors made by the students, and the total time of these errors are recorded, respectively.
