Abstract
Изобретение относитс к измерительной технике. Цель изобретени - расширение технологических возможностей. При контроле шпоночного паза 7 детали 8 в него устанавливают два клина 1 и 2 так, чтобы клин 1, имеющий скос, составл л с боковой стороной паза 7 угол 30-60°. Затем заклинивают клинь 1 и 2. Подвижный измерительный стержень 4 размещают в призматической канавке 9, а неподвижный измерительный стержень 5 ввод т в контакт с внутренней поверхностью детали 8 и снимают показани нутромера 3. Далее вынимают клинь 1 и 2, поворачивают их на 180° и устанавливают в шпоночном пазу 7 так, чтобы скос клина 1 образовывал призматическую канавку 9 с другой боковой стороной шпоночного паза 7. Устанавливают индикаторный нутромер 3 и снимают второй отсчет. Разность показаний индикаторного нутромера вл етс величиной отклонени от симметричности шпоночного паза 7 относительно оси детали 8. 2 ил.This invention relates to a measurement technique. The purpose of the invention is the expansion of technological capabilities. When controlling the keyway 7 of the part 8, two wedges 1 and 2 are installed in it so that the wedge 1, having a bevel, is 30-60 ° with the side of the groove 7. Then wedges 1 and 2 are wedged. A movable measuring rod 4 is placed in a prismatic groove 9, and a fixed measuring rod 5 is brought into contact with the inner surface of the part 8 and the inside meter 3 is measured. Then the wedges 1 and 2 are removed, rotated by 180 ° and set in the keyway 7 so that the bevel of the wedge 1 forms a prismatic groove 9 with the other side of the keyway 7. Install the indicator caliper 3 and remove the second reading. The difference in readings of the gauge caliper is the deviation from the symmetry of the keyway 7 relative to the axis of the part 8. 2 Il.
