Description

Известны приборы дл  опредмени  эксцентричности покрыти  электродов дл  дуговой сварки, состо щие из индуктивного датчика, усилител  и индикатора, или реле, однако они не обеспечивают необходимой точности измерений.Instruments for measuring the eccentricity of the coating of electrodes for arc welding, which consist of an inductive sensor, amplifier and indicator, or a relay, are known, but they do not provide the necessary accuracy of measurements.

Дл  устранени  указанного недостатка предлагаетс  магнитопровод датчика выполнить в виде полого цилиндра, подразделенного на четыре сегмента, снабженных обмотками, включенными в плечи уравновешенной мостовой измерительной схемы, с тем, чтобы при проходе контролируемого электрода сквозь датчик эксцентрическое расположение покрыти  отмечалось нарушением баланса мостовой схемы.To eliminate this drawback, the sensor magnetic circuit is proposed to be made in the form of a hollow cylinder divided into four segments, provided with windings included in the shoulders of a balanced measuring bridge circuit, so that when the monitored electrode passes through the sensor, the eccentric arrangement of the coating is marked by imbalance of the bridge circuit.

Полый стальной цилиндр 1 (см. схему) с разрезанными на четыре сегмент  стенками 2 имеет обмотки 3, расположенные на соответствующих сегментах. Обмотки включены в плечи уравновешенной мостовой измерительной схемы, питаемой от источника переменного тока. Стрелочный ииликатоп 4 фиксирует со.сто ние равновеси  мостовой схемы.A hollow steel cylinder 1 (see diagram) with walls 2 cut into four segments has windings 3 located on the respective segments. The windings are included on the shoulders of a balanced measuring bridge circuit fed from an AC source. The arrow switch and the cathode 4 fixes the equilibrium of the bridge circuit.

Контролируемый электрод перемещаетс  сквозь центральное отверстие прибора; при этом электродное покрытие соприкасаетс  с внутренней поверхностью центрального отверсти  и этим определ ет положение стального электродного стержн  относительно обмоток. Если электродное покрытие не имеет эксцентрицитета, то стальной стержень электрода находитс  в центре отверсти , равновесие мостовой схемы не нару шаетс  и стрелка индикатора стоит на нуле.The monitored electrode moves through the center hole of the instrument; wherein the electrode coating is in contact with the inner surface of the central hole and thereby determines the position of the steel electrode rod relative to the windings. If the electrode coating does not have eccentricity, then the steel rod of the electrode is in the center of the hole, the equilibrium of the bridge circuit is not disturbed, and the indicator needle is at zero.

При наличии эк сцентрицитета электродный стержень смещаетс  от центра отверсти , равновесие нарущаетс  и стрелка индикатора отклон етс .In the presence of eccentricity, the electrode rod is displaced from the center of the hole, the balance is disturbed, and the indicator needle is deflected.

Прибор может быть установлен непосредственно у обмазочного пресса и использоватьс  дл  отбраковки электродов.The device can be installed directly at the coating press and used to reject the electrodes.
