Изобретение относитс  к измерительной технике, в частности к способам поверки автоматов дл  контрол  и сортировки деталей по линейным размерам.The invention relates to a measurement technique, in particular to methods for calibrating automatic machines for monitoring and sorting parts according to linear dimensions.

Известны способы поверки автоматов дл  контрол  и сортировки деталей по линейным размерам, заключающиес  в том, что выборку из партии деталей двукратно сортируют на автомате по группам, подсчитывают после очередной сортировки количество деталей, попавших в каждую группу, и вычисл ют веро тности попадани  деталей в сортировочные группы .Methods are known for calibrating machines for controlling and sorting parts by linear dimensions, such that a sample from a batch of parts is sorted twice on the machine by groups, after the next sorting, the number of parts falling into each group is calculated, and the probabilities of parts getting into sorting are calculated groups.

Однако известные способы позвол ют определить только среднеквадратичное отклонение погрешности срабатывани  на границах интервалов сортировки, а погрешность настройки границ интервалов сортировки, смещение настройки за заданный промежуток времени и разиоразмерность деталей в сортировочных группах известными способами определить невозможно.However, the known methods allow to determine only the standard deviation of the error of operation at the boundaries of the sorting intervals, and the accuracy of the setting of the boundaries of the sorting intervals, the offset of the settings for a given period of time and the razorostirovanie parts in sorting groups cannot be determined by known methods.

С целью повышени  достоверности определени  точности параметров автоматов по предлагаемому способу до сортировки выборки из партии деталей определ ют веро тностные характеристики распределени  формы и размеров деталей во всей партии, а после вычислени  веро тностей попадани  деталей в сортировочные группы, эти данные и веро тностные In order to increase the reliability of determining the accuracy of the parameters of automata using the proposed method, prior to sorting the sample from a batch of parts, the probability characteristics of the distribution of the shape and dimensions of the parts throughout the batch are determined, and after calculating the probabilities of parts falling into the sorting groups, these data and probability

характеристики распределени  ввод т в вычислительную машину и по полученным результатам определ ют точностные параметры автоматов .the distribution characteristics are entered into the computer and the accuracy parameters of the automata are determined from the results obtained.

Поверка автоматов по предлагаемому способу производитс  следующим образом.The verification of automata according to the proposed method is carried out as follows.

Предварительно измер ют форму и размеры деталей выборки из всей партии, например, на кругломере. Затем с помощью методов гармонического анализа и математической статистики определ ют веро тностные характеристики распределени  дифференцированных отклонений формы и размеров дл  всей партии деталей. После проведени  этих операций аттестованную партию деталей рассортировывают на автомате на группы и подсчитывают количество деталей, попавших в каждую группу .The shape and dimensions of the parts of the sample from the entire batch, for example, on a round meter, are preliminarily measured. Then, using the methods of harmonic analysis and mathematical statistics, the probability characteristics of the distribution of differentiated deviations of shape and size for the entire batch of parts are determined. After these operations, the certified batch of parts is sorted on the machine into groups and the number of parts falling into each group is calculated.

Далее повторно рассортировывают детали из каждой группы отдельно и вновь подсчитывают количество деталей, оставшихс  в каждой группе после повторной рассортировки.Next, the parts from each group are re-sorted separately and the number of parts remaining in each group is re-calculated after re-sorting.

Пользу сь полученными результатами, вычисл ют веро тности попадани  деталей в сортировочные группы.Using the results obtained, the probabilities of parts falling into the sorting groups are calculated.

И, наконец, использу  полученные веро тностные характеристики распределени  формы и размеров деталей партии и вычисленные значени  веро тностей попадани  деталей в сортировочные группы, ввод т эти данные в выFinally, using the obtained probabilistic characteristics of the distribution of the shape and dimensions of the parts of a batch and the calculated values of the probabilities of parts falling into the sorting groups, these data are entered into you
