Abstract
Изобретение относитс к металообра-. ботке и может быть использовано при расточке труб методом на раст жение. Целью изобретени вл етс повышение эксплуатационных свойств за счет фиксации пластины . В корпусе 1 установлены сборна пластина 12, 13 и клин 16 с наклонными поверхност ми Л, М и К, взаимодействующий с пластиной и корпусом. При перемещении клина 16 до упора в регулировочный винт 25 пластина раздвигаетс поверхности клина Л и М на заданный размер и приобретает возможность плавани , при отводе клина 16 его поверхности К взаимодействуют с ответными поверхност ми, выполненными в корпусе или стопорит пластину, т.е. лишает ее возможности плавать. 7 ил.FIELD OF THE INVENTION It can be used for boring pipes using the tensile method. An object of the invention is to improve performance by fixing the plate. In the housing 1, a prefabricated plate 12, 13 and a wedge 16 with inclined surfaces L, M and K are installed, which interacts with the plate and the body. When the wedge 16 is moved all the way into the adjusting screw 25, the plate extends the surface of the wedge L and M by a predetermined size and acquires the ability to swim; when the wedge 16 is withdrawn, its surface K interacts with mating surfaces made in the housing or stops the plate, i.e. deprives her of the ability to swim. 7 ill.
