Description

В известных конструкци х индикаторных микрометров одни из мерительных стержней обычно св зан с показывающим прибором при помощи зубчато-рычажного механизма, что не обеспечивает высокой точности замера.In known indicator micrometers, one of the measuring rods is usually associated with an indicating device by means of a toothed-lever mechanism, which does not provide a high accuracy of measurement.

Устройство, выполненное согласно изобретению, лишено указанных недостатков. Сущность изобретени  заключаетс  в том, что один из мерительных стержней выполнен из магнитострикционного материала и снабжен управл ющей катушкой, позвол ющей путем замера электрических величин определ ть соответствующие пм линейные величины .The device, made according to the invention, is devoid of the indicated disadvantages. The essence of the invention is that one of the measuring rods is made of a magnetostrictive material and is equipped with a control coil, which allows measuring the corresponding PM linear values by measuring electrical quantities.

На чертеже схематически представлен общий вид устройства.The drawing shows a schematic overview of the device.

К п тке скобы микрометра 1 через изолирующую прокладку 2 жестко прикреплен стержень 3 из магнитострикционного материала (в рассматриваемом устройстве используетс  стержень с отрицательным магнитострикционным эффектом).A pin 3 of magnetostrictive material is rigidly attached to the clip of the micrometer 1 through the insulating gasket 2 (the device in question uses a rod with a negative magnetostrictive effect).

На стержень 3 надета катушка 4, питаема  от регулируемого источника посто нного тока и рассчитанна  на возможность создани  в стержне магнитной индукции от О до 10 000 гс. По величине изменени  магнитной индукции, котора   вл етс  функцией тока, протекающего через обмотку сердечника, устанавливаетс  зависимость между величиной силы тока, измен ющейс  в зависимости от изменени  дли-i ны. Таким образом, по шкале прибора 5, включенного в цепь катущ-; ки 4 и имеющего шкалу, проградуированную на линейные величины, можно будет определ ть величину размера детали.The coil 4 is worn on the rod 3, fed from an adjustable source of direct current and designed for the possibility of creating a magnetic induction in the rod from 0 to 10 000 gf. The magnitude of the change in magnetic induction, which is a function of the current flowing through the core winding, establishes a relationship between the magnitude of the current, varying with the change in length. Thus, on a scale of the device 5, included in the circuit of the roll-off; 4 and having a scale graduated to linear values, it will be possible to determine the size of the part.

Дл  установки пр.ибора на нуль к мерительным стержн м 6 прикладываетс  некотора  разность потенциалов (от 10 до в), момент контакта которых (точка нул ) замер етс  при помощи гальванометра 7.In order to set the oscillator to zero, some potential difference (from 10 to in) is applied to the measuring rods 6, the moment of contact (point zero) is measured with a galvanometer 7.

Государственный комитет Совета Министров СССР принимает устройство, выполненное согласно изобретению к экспериментальной проверке.The State Committee of the USSR Council of Ministers accepts a device made in accordance with the invention for experimental verification.

Предмет изобретени Subject invention

Ультрамикрометр дл  линейных прецизионных измерений, отличающийс  тем, что, с целью повьпиерш  точности замера, один из мерительных стержней выполнен из магнитострикционного материала и снабжен управл юн1ей катушкой.An ultramicrometer for linear precision measurements, characterized in that, in order to measure accuracy, one of the measuring rods is made of a magnetostrictive material and is equipped with a control coil.
