Abstract
Алмазное долото с механическим креплением резцов, содержащее корпус с присоединительной резьбой, промывочные узлы для очистки забоя от шлама, закрепляемые породоразрушающие резцы PDC, расположенные во втулках из пластичного металла в отверстиях на лопастях, отличающееся тем, что крепление резца PDC осуществляется с помощью пары вставленных с усилием одна в другую конических стопорных втулок - одной с наружной цилиндрической поверхностью, ответной стенке отверстия в лопасти и внутренней конической поверхностью, симметричной оси отверстия, вершиной конуса обращенной в сторону его дна, и другой втулки с внутренней цилиндрической поверхностью, ответной поверхности основания резца PDC и наружной конической поверхностью, симметричной оси отверстия, вершиной конуса обращенной в сторону его входа; в дне отверстия под резец PDC предусмотрено соосное сквозное отверстие в лопасти, меньшее по диаметру, для введения в него и удаления из отверстия ремонтируемого или заменяемого резца PDC осевыми ударами или выпрессовыванием с помощью выколотки для обеспечения поворота изношенного участка и замены его на рабочей режущей кромке разворотом на нужный угол относительно оси или полной замены резца PDC на новый.A diamond bit with mechanical fastening of the cutters, comprising a body with a connecting thread, flushing units for cleaning the bottom of the sludge, fixed PDC rock cutting tools located in ducts made of plastic metal in the holes on the blades, characterized in that the PDC cutter is mounted using a pair inserted with by force of conical locking bushings one into the other - one with the outer cylindrical surface, the counter wall of the hole in the blade and the internal conical surface symmetrical to the axis of the hole , The apex of the cone facing towards the bottom thereof, and the other sleeve with an inner cylindrical surface of the counter surface PDC cutter base and an outer conical surface symmetrical to the bore axis, the cone apex facing in the direction of its inputs; in the bottom of the hole for the PDC cutter, there is a coaxial through hole in the blades, smaller in diameter, for introducing into it and removing from the hole the PDC cutter being repaired or replaced by axial impacts or by extrusion using a punch to ensure rotation of the worn section and replacing it on the working cutting edge with a turn at the desired angle relative to the axis or completely replace the PDC cutter with a new one.
