Abstract

Изобретение относитс  к механизированным устройствам дл  зат жки резьбовых соединений в машиностроении . Цель изобретени  - повьшение эффективности за счет увеличени  усили  зат жки. Поршень 2 навинчиваетс  на шпильку 9. В цилиндр 1 подаетс  масло под давлением, он перемещаетс  вниз, воздейству  на концы рычагов 6, противоположные концы которых воздействуют на нажимное кольцо 4. Поршень 2 под действием нажимного кольца 4 и давлени  масла перемещаетс  вверх и раст гивает шпильку 9. Доворот гайки 10 осуществл етс  воротком через паз 8. 2 ил.This invention relates to mechanized devices for tightening threaded connections in mechanical engineering. The purpose of the invention is to increase efficiency by increasing the tightening force. The piston 2 is screwed onto the stud 9. The cylinder 1 is supplied with oil under pressure, it moves downward, acting on the ends of the levers 6, the opposite ends of which act on the pressure ring 4. The piston 2 under the action of the pressure ring 4 and the oil pressure moves up and stretches the stud 9. Turning the nut 10 is carried out by the knob through the groove 8. 2 Il.
