Abstract

Изобретение относитс  к оборудованию дл  сборочных работ, в частности к рычажным гайковертам,и предназначено дл  сборки крупных резьбовых соединений. Цель изобретени  - упрощение конструкции и уменьшение веса. При работе трещеточнын ключ с руко ткой 1 устанавливаетс  на зат гиваемое соединение, а упор - на соседнюю крепежную деталь. При подаче давлени  в силовой цилиндр 4 происходит зат жка. При холостом ходе плоские пружины 9, охватывающие шток 8, обеспечивают соосность упора и штока 8, что исключает поворот упора вокруг оси резьбового соединени . 3 ил.The invention relates to assembly equipment, in particular to lever wrenches, and is intended to assemble large threaded connections. The purpose of the invention is to simplify the design and reduce the weight. In operation, the ratchet key with handle 1 is placed on the clamped joint, and the emphasis is placed on the adjacent fastener. When the pressure is applied to the power cylinder 4, a puff occurs. When idling, the flat springs 9 covering the rod 8 ensure the alignment of the stop and the rod 8, which prevents the stop from turning around the axis of the threaded joint. 3 il.
