Изобретение относитс к измерительно технике.This invention relates to a measurement technique.

Известны способы новерки точности вращени объектов, установленных на кругломер с регистрацией нескольких параметров на одной круглограмме tilИзвестны способы новерки приборов дл измерени некруглости с помощью эталонного прибора дл измерени некруглости, заключающиес в том, что контрольный об разец измер ют последовательно на эталои ном и повер емом приборе дл измерени некруглости, результаты измерени записывают на одну круглограмму и сопоставл ют результаты загиюи 2, Этот способ по технической сущности в.а отс наиболее близ- км;-; к данному изоб 1етен11Ю.Known methods for the rotation of the accuracy of objects installed on the round meter with the registration of several parameters on a single circular diagram til Known methods of checking devices for measuring out-of-roundness using a reference device for measuring out-of-roundness are known in that the test sample is measured successively on a standardized and calibrated device to measure the non-roundness, the measurement results are recorded on one circular pattern and the results of prospective 2 are compared. This method is technically based on the most near km; -; to this image

Claims

USSR 338136, set on the table 2 reference device, for example, mod. Ta.LIROND - 2, coaxially with schnushdel 3 last. The control sample 4 is installed on the table 5 of the node of the exemplary rotation of the PEMO device and brought with it to the ampoule the measuring tip 6 of the reference device. Then, the lard 3 of the reference device is rotated, the sensor 7 signals through the amplifier 8 and cflNfo scribe 9 are recorded on the roundup record. After the end of the recording, the measuring tip 6 is set to a floating position and the recording is repeated, but the spindle 3 of the reference device is fixed and the table 5 is rotated. Now, with the test sample 4. As in the first case, the signals of sensor 7 pass through amplifier 8 to the recorder 9. For greater visibility, before the second recording, the recorder's pen is shifted radially by a small amount sufficient to read the first and second records separately. To eliminate the influence of the frequency response of the recorder, the speed of the speed of the NIN of the table 5 during the second recording makes the spindle rotation speed of the reference instrument. The records obtained are compared visually or according to the current criteria, Claim 1, Method of calibration npvi6opa for 11me. early non-rounding using a reference instrument and a control sample, which consists in the fact that there is a sequential record for one circular program; The profile of the control sample is compared and the obtained records are compared, in order to improve the accuracy and simplify the verification, the node of the model rotation of the rotating device is installed coaxially with the standard spindle, the first record is made with a stationary control sample and the spindle of the reference device, and the second with a fixed spindle of the reference instrument and a rotating control sample. 2. A method according to claim 1, characterized in that for both records a measuring tip, a sensor, an amplifier and a recorder of a reference instrument are used.
