Abstract
Изобретение относитс к механосборочному инструменту дл зат жки резьбовых соединений. Цель изобретени - повышение надежности. Предварительно на резьбовой конец шпильки 5 навинчивают гайку 11 до соприкосновени с торцом собираемой детали 10. Затем устройство устанавливают на свободный резьбовой конец шпильки 5, и враща цилиндр 1, наворачивают элемент 4 захвата на резьбовой конец шпильки 5 до его упора в гайку 11. Затем в полость цилиндра 1 под давлением подают рабочую жидкость. Под давлением последней цилиндр 1 перемещаетс относительно поршн 3 и через элемент 4 захвата передает усилие на шпильку 5. При достижении заданного давлени шпилька 5 удлин етс на заданную величину, при этом между гайкой 11 и торцом собираемой детали 10 образуетс зазор. После этого гайку 11 наворачивают на шпильку 5 до выборки зазора , а затем сбрасывают давление в цилиндре 1 и сворачивают устройство, с резьбового конца шпильки 5. 2 ил.The invention relates to a mechanical assembly tool for tightening threaded joints. The purpose of the invention is to increase reliability. The nut 11 is preliminarily screwed onto the threaded end of the stud 5 until it contacts the end of the assembled part 10. Then, the device is mounted on the free threaded end of the stud 5, and turning the cylinder 1, the gripping element 4 is screwed onto the threaded end of the stud 5 until it stops in the nut 11. Then the cavity of the cylinder 1 under pressure serves the working fluid. Under pressure of the latter, the cylinder 1 moves relative to the piston 3 and transfers force through the gripping element 4 to the pin 5. When the set pressure is reached, the pin 5 is extended by a predetermined amount, and a gap is formed between the nut 11 and the end face of the assembled part 10. After that, the nut 11 is screwed onto the pin 5 until the clearance is removed, and then the pressure in the cylinder 1 is released and the device is turned off from the threaded end of the pin 5. 2 il.
