Description

Изобретение относитс  к области техники линейных измерений, а именно к средствам статистического контрол  качества продукции .The invention relates to the field of linear measurement technology, namely to the means of statistical control of product quality.

Известны устройства дл  определени  размаха вырьировани , содержащие статистический индикатор с пассивной стрелкой, промежуточное звено, несущее измерительный наконечник и взаимодействующее со статистическим индикатором, измерительный столик дл  установки контролируемого объекта и арретир измерительного столика.Devices for determining the span of the extinction are known, containing a statistical indicator with a passive arrow, an intermediate link carrying the measuring tip and interacting with the statistical indicator, a measuring table for mounting the object to be monitored, and a measuring table arresting device.

Недостатком известных устройств  вл етс  то, что они требуют фиксации начального положени  измерительного штока статистического индикатора и дают правильные результаты лищь в том случае, если варьируемые размеры лежат по обе стороны от начального положени . Управл емый фиксатор измерительного щтока усложн ет конструкцию статистического индикатора, делает его недостаточно надежным, а требование двустороннего расположени  отклонений размеров от начального положени  затрудн ет использование известных устройств, поскольку до начала измерений распределение размеров неизвестно .A disadvantage of the known devices is that they require fixing the initial position of the measuring rod of the statistical indicator and give correct results if the variable dimensions lie on either side of the initial position. The controlled clamp of the measuring rod complicates the design of the statistical indicator, makes it insufficiently reliable, and the requirement of two-sided positioning of the size deviations from the initial position makes it difficult to use known devices, since the size distribution is unknown before the measurements start.

С целью упрощени  конструкции статистического индикатора и облегчени  эксплуатации устройства послед} ее снабжено вторымIn order to simplify the design of the statistical indicator and facilitate the operation of the device, the device} is equipped with a second

статистическим индикатором с пассивной стрелкой, взаимодействующим с промежуточным звеном параллельно первому статистическому индикатору, и арретиром измерительногоstatistical indicator with a passive arrow, which interacts with an intermediate link parallel to the first statistical indicator, and a measuring head

штока второго статистического индикатора.stock of the second statistical indicator.

Устройство не требует механизма фиксации измерительных щтоков и позвол ет обойтись одной пассивной стрелкой на каждом из статистических индикаторов.The device does not require a fixation mechanism for the measuring taps and allows you to do with one passive arrow on each of the statistical indicators.

На чертеже изображено предлагаемое устройство .The drawing shows the proposed device.

Устройство содержит стойку (не показана), измерительный столик 1, промежуточное звено 2 с измерительным наконечником 3, два статистических индикатора 4 и 5 соответственно с измерительными 6 и пассивными 7 стрелками , арретир 8 измерительного столика 1 и арретир 9 статистического индикатора 5. Измерительные щтоки 10 и 11 статистическихThe device contains a rack (not shown), measuring table 1, intermediate 2 with measuring tip 3, two statistical indicators 4 and 5, respectively, with measuring 6 and 7 passive arrows, arresting device 8 of measuring table 1 and arresting device 9 of statistical indicator 5. Measuring brushes 10 and 11 statistical

индикаторов 4 и 5 взаимодействуют с промежуточным звеном 2. Арретир 9 воздействует на измерительный щток 11 статистического индикатора 5 через штангу 12 и вилку 13. Устройство работает следующим образом.indicators 4 and 5 interact with the intermediate link 2. The arresting device 9 acts on the measuring brush 11 of the statistical indicator 5 through the rod 12 and the plug 13. The device operates as follows.

На измерительный столик 1 устанавливают образцовую деталь с известным размером и устанавливают измерительные стрелки 6 статистических индикаторов на одинаковые, соответствующие размеру образцовой детали отметки . Если образцова  деталь принадлежитA measuring piece with a known size is installed on the measuring table 1 and the measuring arrows of 6 statistical indicators are set to the same elevations corresponding to the size of the model part. If the sample item belongs
