At the same time, the boring head must have a design that provides at least a partial open external access to its slider.
Таким образом, после установки измерительного устройства на расточную головку будет обеспечено неподвижное соединение корпуса измерительного устройства с неподвижной частью расточной головки, одновременно будет обеспечена связь между ползуном измерительного устройства и ползуна расточной головки. При этом перемещение ползуна расточной головки будет вызывать аналогичное взаимообусловленное перемещение ползуна измерительного устройства. Thus, after installing the measuring device on the boring head, a fixed connection of the housing of the measuring device with the fixed part of the boring head will be provided, at the same time, communication will be ensured between the slider of the measuring device and the slider of the boring head. In this case, the movement of the slider of the boring head will cause a similar interdependent movement of the slider of the measuring device.

«Осуществление изобретения» "Implementation of the invention"
Заявляемое измерительное устройство содержит корпус 1, опорная сторона которого 2 выполнена магнитной. Для этого или сама опорная сторона 2 является магнитом или же к стороне 2 прикреплены магниты. Сила магнитов выбирается из условия обеспечения надежного примагничивания (прикрепления) опорной стороны 2 измерительного устройства к неподвижной части расточной головки. Другая сторона 3 корпуса 1 называется функциональной и выполнена с прорезью 4. Вдоль прорези 4 снаружи размещен ползун 5 измерительного устройства, а изнутри - измерительная линейка 6, при этом ползун 5 и линейка 6 жестко связаны между собой соединительными элементами 7, например, болтами. Ползун 5 установлен с возможностью взаимного перемещения с линейкой 6 вдоль прорези 4. Ползун 5 выполнен из магнитного материала или же снабжен магнитами, жестко соединенными с наружной поверхностью ползуна 5. Сила магнитов ползуна 5 выбирается из условия надежного соединения (примагничивания) ползуна 5 к ползуну расточной головки. Внутри корпуса 1 неподвижно (жестко) размещен датчик 8, предназначенный для измерения перемещения линейки 6; микропроцессор 9, связанный с датчиком 8 и предназначенный для преобразования сигнала с датчика 8 и передачи информации на устройство вывода информации 10 (например, монитор). Также внутри корпуса 1 размещен элемент питания 1 1 , предназначенный для питания датчика 8, микропроцессора 9 и устройства вывода информации 10. Для работы корпус 1 измерительного устройства устанавливается на неподвижную часть расточной головки 12, при этом удержание измерительного устройства на неподвижной части расточной головки обеспечено за счет силы магнита опорной стороны 2 и магнитных свойств неподвижной части расточной головки. Одновременно,
измерительного устройства устанавливается так, чтобы ползун 5 измерительного устройства был связан (примагничен) с ползуном 13 расточной головки 12, при этом удержание ползуна 5 измерительного устройства на ползуне 13 расточной головки обеспечивается за счет силы магнита ползуна 5 и магнитных свойств ползуна 13 расточной головки 12. The inventive measuring device comprises a housing 1, the supporting side of which 2 is made magnetic. For this, either the supporting side 2 itself is a magnet or magnets are attached to the side 2. The strength of the magnets is selected from the condition of ensuring reliable magnetization (attachment) of the support side 2 of the measuring device to the fixed part of the boring head. The other side 3 of the housing 1 is called functional and is made with a slot 4. A slider 5 of the measuring device is placed outside the slot 4 on the outside, and a measuring ruler 6 is placed inside, while the slider 5 and the ruler 6 are rigidly connected to each other by connecting elements 7, for example, bolts. The slider 5 is installed with the possibility of mutual movement with the ruler 6 along the slot 4. The slider 5 is made of magnetic material or provided with magnets rigidly connected to the outer surface of the slider 5. The strength of the magnets of the slider 5 is selected from the condition of reliable connection (magnetization) of the slider 5 to the boring slide heads. Inside the housing 1 is stationary (rigidly) placed sensor 8, designed to measure the movement of the ruler 6; a microprocessor 9 connected to the sensor 8 and designed to convert the signal from the sensor 8 and transmit information to the information output device 10 (for example, a monitor). Also, a battery 1 1 is located inside the housing 1, designed to power the sensor 8, microprocessor 9, and information output device 10. For operation, the housing 1 of the measuring device is mounted on the fixed part of the boring head 12, while holding the measuring device on the fixed part of the boring head is provided for due to the strength of the magnet of the support side 2 and the magnetic properties of the fixed part of the boring head. At the same time the measuring device is installed so that the slider 5 of the measuring device is connected (magnetized) with the slider 13 of the boring head 12, while the retention of the slider 5 of the measuring device on the slider 13 of the boring head is ensured by the strength of the magnet of the slider 5 and the magnetic properties of the slider 13 of the boring head 12.
Кроме опорной стороны 2 и ползуна 5, все остальные конструктивные элементы заявляемой измерительной головки выполнены из немагнитного материала. Также из магнитного материала должны быть выполнены участки расточной головки и ползуна расточной головки, с которыми соединяется опорная сторона 2 и ползун 5 измерительного устройства. In addition to the supporting side 2 and the slider 5, all other structural elements of the inventive measuring head are made of non-magnetic material. Also, sections of the boring head and the slider of the boring head with which the supporting side 2 and the slider 5 of the measuring device are connected should be made of magnetic material.
Заявляемое устройство применимо для всех типов расточных головок, у которых обеспечен, хотя бы в части доступ к наружной поверхности ползуна расточной головки. The inventive device is applicable to all types of boring heads, which provided, at least in part, access to the outer surface of the slide of the boring head.
Заявляемое устройство работает следующим образом. The inventive device operates as follows.
При перемещении ползуна 13 расточной головки происходит одновременное взаимообусловленное перемещение ползуна 5 измерительного устройства. Ползун 5 перемещается вдоль прорези 4, одновременно с ползуном 5 вдоль прорези 4 перемещается линейка 6, жестко соединенная с ползуном 5. Датчик 8 измеряет значение перемещения линейки 6, движущейся относительно датчика 8, и передает соответствующую информацию на микропроцессор 9, который преобразует сигнал с датчика 8 в вид, позволяющий визуализировать информацию о значении перемещения линейки 6 или же перевести информацию о значении перемещения линейки 6 для иной формы вывода информации или для передачи информации на иное устройство, например, смартфон. Связь микропроцессора 9 с внешним устройством может осуществляться посредством проводной связи, через канал «блютуз», Интернет и т.п. Вид связи выбирается исходя из доступного вида связи, а также с учетом удобства обработки информации. When moving the slider 13 of the boring head, simultaneous interdependent movement of the slider 5 of the measuring device occurs. The slider 5 moves along the slot 4, simultaneously with the slider 5 along the slot 4 the ruler 6 moves, rigidly connected to the slider 5. The sensor 8 measures the displacement value of the ruler 6, moving relative to the sensor 8, and transmits the corresponding information to the microprocessor 9, which converts the signal from the sensor 8 into a view that allows you to visualize information about the value of the movement of the ruler 6 or to transfer information about the value of the movement of the ruler 6 for a different form of output of information or for transferring information to another device, for example p smartphone. The communication of the microprocessor 9 with an external device can be carried out by means of a wired connection, via a bluetooth channel, the Internet, etc. The type of communication is selected based on the available type of communication, as well as taking into account the convenience of processing information.
Ползун 13 расточной головки связан с резцом, следовательно, заявляемое измерительное устройство может быть использовано для измерения перемещения резца расточной головки.
The slider 13 of the boring head is connected with the cutter, therefore, the inventive measuring device can be used to measure the movement of the cutter of the boring head.
