Abstract

Предложено сверлильное устройство (1), содержащее режущее устройство (50) и направляющий элемент (2), имеющий продольную ось (А-А), причем конфигурация устройства такова, что в процессе работы режущее устройство взаимодействует с направляющим элементом при вращении режущего устройства вокруг продольной оси, а форма направляющего элемента такова, что обеспечивает поворот режущих блоков (51) режущего устройства в поперечном направлении относительно продольной оси по мере того, как режущие средства перемещаются в направлении, которое в целом параллельно указанной продольной оси. В предпочтительном варианте выполнения настоящего изобретения направляющий элемент имеет профиль (6) в форме усеченного конуса для формирования отверстия (20) соответствующей формы. Формой отверстия, выполняемого предлагаемым устройством, можно управлять с высокой точностью. Предлагаемое устройство особенно полезно для развертывания заранее выполненных отверстий, используемых для установки анкерных болтов.Международная заявка была опубликована вместе с отчетом о международном поиске.A drilling device (1) comprising a cutting device (50) and a guide element (2) having a longitudinal axis (A-A) is proposed, the device configuration being such that during operation the cutting device interacts with the guide element when the cutting device rotates around the longitudinal axes, and the shape of the guide element is such that it ensures that the cutting units (51) of the cutting device rotate in the transverse direction relative to the longitudinal axis as the cutting means move in a direction that is generally It is parallel to said longitudinal axis. In a preferred embodiment of the present invention, the guide element has a profile (6) in the shape of a truncated cone for forming an opening (20) of a corresponding shape. The shape of the holes performed by the proposed device can be controlled with high accuracy. The proposed device is particularly useful for deploying pre-made holes used to install anchor bolts. The international application was published along with an international search report.
