(54) СПОСОБ ПРОТЯГИВАНИЯ ЦИЛИНДРИЧЕСКИХ ОТВЕРСТИЙ(54) METHOD FOR EXTRACTING CYLINDRICAL HOLES

В ПАРАЛЛЕЛЬНЫХ СТЕНКАХ КОРПУСОВ И УСТРОЙСТВОIN PARALLEL WALLS OF CASES AND DEVICE

ДЛЯ ЕГО ОСУЩЕСТВЛЕНИЯFOR ITS IMPLEMENTATION

Устройство, на котором устанавливаетс  корпус 1 издели  дл  обработки, состоит из основани  2, люнетов 3, в отверсти х которых подвижно установлены направл ющие втулки 4, в отверстии которых располагают прот жку 5 с лысками 6. Люнеты 3 снабжены подпружиненными фиксаторами 7, соединенными между собой общей перемычкой 8. Направл ющие втулки 4 снабжены руко тками 9, соединенными между собой общей перемычкой 10. В люнетах 3 выполнены радиальные пазы 11 с наклонными стенками, предназначенными дл  расположени  в них руко ток 9, а в направл ющих втулках 4 - пазы 12, предназначенные дл  взаимодействи  с подпружиненными фиксаторами 7. В радиальных отверсти х 13 направл ющих втулок 4 расположены регулировочные винты 14, концы 15 которых контактируют с лысками 6 прот жек 5.The device on which the body 1 of the treatment article is installed consists of a base 2, lunettes 3, in the openings of which guiding sleeves 4 are movably mounted, in the openings of which stretch 5 is arranged with bald heads 6. The steady arms 3 are equipped with spring-loaded latches 7 connected between a common jumper 8. Guides 4 are provided with handles 9, interconnected by a common jumper 10. In lunettes 3 there are radial grooves 11 with inclined walls intended for positioning the handle 9 in them, and in guides the sleeves ax 4 are grooves 12 for engaging with spring-loaded clips 7. Adjusting screws 14 are located in the radial holes 13 of the guide bushings 4, the ends 15 of which are in contact with the flats 6 of the hook 5.

Устройство дл  осуществлени  предлагаемого способа расщир ет технологические возможности, позвол   обрабатывать р д цилиндрических отверстий в параллельных стенках корпусов.The apparatus for carrying out the inventive method cleans up the technological capabilities by allowing the processing of a number of cylindrical holes in the parallel walls of the shells.
