Abstract

Изобретение относитс к механизации сборки резьбовых соединений и может быть использовано в машиностроении в сборочных процессах Целью изобретени вл етс повышение надежности и расширение технологических возможностей. При перемещении штока 15 с т гой 16 влево рычаг 6 вместе с рабочей головкой 9 поворачиваетс против часовой стрелки, при этом собачка 11 проскальзывает по зубь м рабочей головки 9, а собачка 13 стопорит ее. Упруга пластина 18 (права ) под воздействием грузовой втулки 25 сначала амортизирует, а затем при переходе рычага 24 в левое положение сообщает дополнительную энергию грузовой втулке 25, обеспечива полное переключение поворотного плунжера распределительного устройства 7. При этом сжатый воздух подаетс в штоковую полость пневмоцилиндра 3 и рычаг 6 с рабочей головкой 9 поворачиваетс по часовой стрелке. Рабоча собачка 11 входит в зацепление с зубь ми рабочей головки 9, а фиксирующа собачка 13 проскальзывает по зубь м рабочей головки 9. При вращении гаек в обратном направлении обе собачки, рабоча и фиксирующа , переключаютс в обратное положение. 1 з п.ф-лы. 4 ил. (Л СThe invention relates to the mechanization of assembling threaded connections and can be used in mechanical engineering in assembly processes. The aim of the invention is to increase the reliability and expand technological capabilities. When moving the rod 15 with the pulley 16 to the left, the lever 6 together with the working head 9 rotates counterclockwise, while the dog 11 slips along the teeth of the working head 9, and the dog 13 locks it. The elastic plate 18 (right) under the influence of the cargo sleeve 25 first absorbs, and then when the lever 24 moves to the left position, it provides additional energy to the cargo sleeve 25, ensuring full switching of the rotary plunger of the distribution device 7. At the same time, the compressed air is supplied to the rod end of the pneumatic cylinder 3 and the lever 6 with the operating head 9 is rotated clockwise. The working dog 11 engages with the teeth of the working head 9, and the locking dog 13 slips along the teeth of the working head 9. As the nuts are rotated in the opposite direction, both the working and locking dogs are reversed. 1 з п.ф-лы. 4 il. (Ls

Claims

1. A device for assembling threaded connections, comprising a housing, a ratchet disposed thereon with a ratchet wheel in the form of a working head and a working dog, an operating cylinder pivotally connected to the housing and the ratchet mechanism, the control system of the worker

a cylinder with a spool valve, the plunger of which is kinematically connected to the pneumatic cylinder rod by means of a rotary lever rigidly fixed at one end of the pneumatic cylinder rod with a thrust and elastic element, one end of which is designed to interact with the rotary lever, which is different. what. in order to increase reliability, the spool valve

made with a rotary plunger, on which a rotary lever is fixed at one end, the elastic element is made in the form of plates fixed at one end of the tension, and the device is equipped with a cargo hub,

fixed at the free end of the pivot arm for alternately interacting with the free ends of the plates.

2. Pop 1 device, characterized in that, in order to expand technological capabilities by providing reversal of the ratchet mechanism and preventing the nuts from turning during the return stroke of the ratchet mechanism, the working pawl is made with two teeth symmetrically with respect to the axis of rotation, the ratchet wheel double-sided action, and the device is equipped with a fixing pawl mounted on the body with two teeth, symmetrical to the axis of rotation, for interacting with the teeth of the ratchet wheel.
