Description
(54) РАЗЪЕМНОЕ СОЕДИНЕНИЕ ТИПА ЛАСТОЧ ШН ХВОСТ (54) CONNECTOR JOINT TYPE OF SWALLOWS TILT TYPE
II
Изобретение касаетс соединений, а именно креплени сменных шарошек в бу-ревом расширителе.The invention relates to connections, namely the attachment of interchangeable cones in a bumpy extender.
Известно крепление сменных шарошек в буровом расширителе при помощи штифта i. Недостаток такого креплени затспючаетс в ненадежности его использовани в раздвижных расширител х.Known mounting interchangeable cones in the drill extender using pin i. The disadvantage of such an attachment is put to sleep in the unreliability of its use in sliding extenders.
Известно также разъемное соединение типа ласточкин хвост, содержащее подпружиненный фиксатор дл предотвращени перемещени трапециевидного выступа в ответном пазу 2.It is also known to have a dovetail-type detachable joint containing a spring-loaded retainer to prevent the trapezoidal protrusion from moving in the response groove 2.
Недостатком указанного разъемного соединени вл етс невозможность его использовани в расширителе,,The disadvantage of this detachable connection is the impossibility of its use in the expander,
Цель изобретени - расширение области применени разъемного соединени типа ласточкин .хвост, например дл использовани его при соединении оси сменной шарошки с лапой расширигел .The purpose of the invention is to expand the field of application of the dovetail-type detachable joint, for example, to use it when connecting the axis of the interchangeable roller cone with the foot of the expander.
Указанна цель достигаетс гем, что фиксатор вьтолнен в виде стержн , , рый расположен внутри оси шарошки, аThis goal is achieved by heme, that the retainer is made in the form of a rod, which is located inside the axis of the cone, and
трапециевидный выступ выполнен в виде пластины с конусным отверстием под стерн-сепь.Trapezoidal protrusion is made in the form of a plate with a tapered hole under the stern-sep.
На чертеже . показан продольный разрез по оси шарошки расширител и вид А.In the drawing. shows a longitudinal section along the axis of the roller cutter and view A.
Разъемное соединение включает шарошку 1, закрепленную на оси 2 в лапе 3 расширител . Между осью 2 и шарошкой 1 размещены опорные втулки 4, ар-; мированные твердым сплавом 5. Дл предотвращени проворачивани втулок они имеют бурты 6. Сменность шарошек обеспечиваетс подпружиненным фиксатором 7, который, попада в конусное отверстие трапециевидной пластины 8, образует неподвижное замковое соединение. При освобождении пластины 8 от фиксатора 7 она может перемешатьс в ответном пазу 9 лапы 3, что позвол ет производить монтаж и демонтаж шарошек.A detachable connection includes a roller cutter 1, fixed on the axis 2 in the paw 3 of the expander. Between the axis 2 and the roller cutter 1 there are support sleeves 4, ap-; The machined carbide 5. To prevent the sleeves from turning, they have shoulders 6. Replacing the cones is provided with a spring-loaded clamp 7, which, falling into the tapered hole of the trapezoidal plate 8, forms a fixed locking connection. When releasing the plate 8 from the retainer 7, it can mix in the counter groove 9 of the paw 3, which allows for the assembly and disassembly of the cones.
