(54) СПОСОБ ИЗМЕРЕНИЯ ЛИНЕЙНЫХ РАЗМЕРОВ ПОЛЫХ ИЗДЕЛИЙ(54) METHOD OF MEASURING LINEAR DIMENSIONS OF HOLLOW PRODUCTS

Изобретение относитс  к неразруша щему контролю и может быть использовано дл  контрол  линейных размеров полых и-зделий, имеющих сложную форму Известен способ измерени  внутрен него диаметра отьерстий, заключающий с  в том, что в отверстие помещают пневмопробку и измер ют параметры воздушного потока, прошедшего через контролируемое отверстие П. Однако этот способ не позвол ет проводить измерени  изделий сложной формы. Наиболее близким к изобретению по texничecкoй сущности и достигаемому результату  вл етс  способ измерени  линейных размеров полых изделий , заключающийс  в том, что на одном конце издели  возбуждают звуковые волны, принимают звуковые волны на другом его конце, измер ют их параметры и по ним суд т о линей ных размерах полых изделий 2 . Однако известный способ не позвол ет проводить измерени  внутреннего диаметра труб, особенно с малыми диаметрами и с осью, отличной от пр мой линии. Цель изобретени  - измерение внутреннего диаметра полого издели  в каждом его сечении. Эта цель достигаетс  тем, что в изделие помещают шарик, диаметр которого меньше номинального диаметра издели , и перемещают его вдоль оси полого издели . . На чертеже представлено устройство , реализующее предлагаемый способ . Устройство состоит из двух патрубков 1 и 2, выполненных например, из резины, между которыми вставлена измер ема  труба 3 с введенным во внутрь шариком , В патрубок 1 вмонтирован источник 5 звуковых колебаний,, соединенный со звуковым генератором 6, а в патрубок 3 - приемник 7 звукоThe invention relates to non-destructive testing and can be used to control the linear dimensions of hollow surfaces and having a complex shape. There is a known method for measuring the inner diameter of the openings, which implies that a pneumatic tube is placed in the hole and the parameters of the air flow passed through bore P. However, this method does not allow measurements of products of complex shape. The closest to the invention by the essence of the invention and the achieved result is the method of measuring the linear dimensions of hollow products, which means that sound waves are excited at one end of the product, sound waves are received at the other end, their parameters are measured and measured. linear dimensions of hollow products 2. However, the known method does not allow measurements of the internal diameter of pipes, especially with small diameters and with an axis other than a straight line. The purpose of the invention is to measure the internal diameter of the hollow article in each section. This goal is achieved by placing a ball in the product, the diameter of which is less than the nominal diameter of the product, and moving it along the axis of the hollow product. . The drawing shows a device that implements the proposed method. The device consists of two nozzles 1 and 2, made for example of rubber, between which a measuring tube 3 is inserted with a ball inserted inside. A source of 5 acoustic waves, connected to a sound generator 6, is mounted into nozzle 1, and a receiver is connected to nozzle 3. 7 sound
