Abstract
Изобретение относитс к измерительной технике. Цель изобретени - повышение точности. При контроле радиуса части сферы 5 и его поверхности подвод т измерительные наконечники 3 и 4 предварительно настроенных отсчетных узлов 1 и 2. Располагают измерительные наконечники 3 и 4 параллельно нормали А, проход щей через вершину части сферы 7 на равных рассто ни х между собой и нормалью А. Радиус сферы R определ ют по формуле: R=√3C2-H2/4H2+4C2, где C - рассто ние между ос ми измерительных наконечников 3 и 4This invention relates to a measurement technique. The purpose of the invention is to improve accuracy. When controlling the radius of a part of sphere 5 and its surface, measuring tips 3 and 4 of preset reference nodes 1 and 2 are supplied. Measuring tips 3 and 4 are parallel to normal A passing through the top of part of sphere 7 at equal distances between themselves and A. The radius of the sphere R is determined by the formula: R = √3C 2 -H 2 / 4H 2 + 4C 2 , where C is the distance between the axes of the measuring tips 3 and 4
H - разность показаний отсчетных узлов 1 и 2. 1 ил.H is the difference between the readings of the reference nodes 1 and 2. 1 Il.
Description
Изобретение относитс к измерительной технике.This invention relates to a measurement technique.
Цель изобретени - повышение 1 оч- ности.The purpose of the invention is to increase 1 pay.
На чертеже представлена схема устройства реализапии способа.The drawing shows a diagram of the device implementation method.
Устройство содержит отсчетные узлы 1 п 2 с измерительными стержн ми 3 и 4 , расположенными параллельно нормали А на раЕзных рассто ни х между нормалью А и между собой.The device contains readout nodes 1 p 2 with measuring rods 3 and 4 located parallel to the normal A at different distances between the normal A and between themselves.
Способ контрол осуществл етс следующим образом.The control method is carried out as follows.
По эталонной детали отсчетные узлы 1 и 2 настраивают на разность h высот профил на рассто ни х с. Затем к поверхности части сферы , расположенной на столе 6, подвод т измерительные наконечники 3 и 4 отсчетных узлов 1 и 2 и располагают оба измерительных наконечникаFrom the reference part, the readout nodes 1 and 2 tune the difference in profile heights h to distances c. Then, the measuring tips 3 and 4 of the reference nodes 1 and 2 are brought to the surface of the part of the sphere located on the table 6, and both measuring tips are arranged
