Description

Изобретение относитс  к металлообработке и может быть использовано в ашиационной промышленности.The invention relates to metalworking and can be used in the acceleration industry.

Известны сверла кольцевые, содержащие корпус с режущей частью, в центральном отверстии которых установлен направл ющий стержень Ц1. Однако такие сверла не обеспечивают возможности удержани  и выемки вырезанной части тонкостенной детали из внутренней полости издели .Circular drills are known, comprising a housing with a cutting part, in the central hole of which a guide rod C1 is installed. However, such drills do not provide the ability to hold and dig the cut-out portion of the thin-walled part from the internal cavity of the product.

, С целью обеспечени  удержани  вырезанной части тонкостенной детали и извлечени  ее наружу в предлагаемом сверле конец стержн  выполнен в виде, цанги.In order to maintain the cut part of the thin-walled part and extract it to the outside in the proposed drill, the rod end is made in the form of a collet.

На чертеже изображено предлагаемое сверло.The drawing shows the proposed drill.

Сверло содержит корпус 1 с режущей частью 2, В центральном отверстии корпуса установлен направл ющий стержень 3, который зафиксирован в корпусе посредством винта 4. Конец стержн  выполнен в виде цанги 5.The drill bit includes a housing 1 with a cutting part 2. A guide rod 3 is installed in the central opening of the housing, which is fixed in the housing by means of a screw 4. The rod end is made in the form of a collet 5.

Сверло работает следующим образом.The drill works as follows.

Сверло крепитс  в пневматической бормашине ,В предварительно просверленное отверстие в тонкостенном корпусе издели  вставл етс  цанга 5, котора  имеет входную конусную часть. После ввода в отверстие лепестки цанги раскрываютс  и принимают первоначальное положение. После этого cвef)лoм вырезаетс  в тонкостенном корпусе диск, причем цанга не дает вырезанной части упасть внутрь издели .The drill is fastened in a pneumatic drill. A collet 5 is inserted into the pre-drilled hole in the thin-walled body of the product, which has an inlet cone part. After insertion into the hole, the petals of the collet open and take the initial position. After this, the cvef lom is cut into a thin-walled casing with a disk, and the collet prevents the cut part from falling inside the product.
