CORE SAWING MACHINE

FIELD: mining.SUBSTANCE: invention relates to geological prospecting and can be used for sawing rock core. Machine comprises a working table with a fastening unit of the core to be sawed, a drive of the working member in the form of a diamond cutting wheel and a feeder of the working member. Core fastening unit is movable in two mutually perpendicular directions relative to the working table, and the sawed core is fixed with a clamp by means of a tightening screw, and on the working table there is a guide on which the vice is rigidly fixed in the form of a semicircle and a fixed nut, and clamp with a core is fitted in the vise, and the clamp is pressed against the vise by a pusher which is axially movable by a screw with a handle relative to the fixed nut, and the feeder of the working member is made in the form of a rack rigidly fixed with nuts on the working table, and on the rack, there is a vertically axially movable drum with a rotating handle and a drive of a diamond cutting wheel fixed to each other, and on the drum a cable is wound which, on one side, the cable is rigidly fixed to the lower end of the rack, and on the other side the cable is rigidly fixed to a tensioner installed on the upper end of the rack, and the drive is made in the form of a high-speed spindle with a converter, which allows smoothly adjusting the frequency of rotation of the diamond cutting wheel, depending on the hardness of the sawed core.EFFECT: simplified and improved construction of the working member feeder, higher accuracy of core cuts, reduced wear of the diamond cutting wheel, as well as expanded functionality of the machine for sawing the core and reduced metal capacity of the structure.1 cl, 3 dwg Изобретение относится к области геологоразведочных работ и может быть использовано для распиловки керна горных пород. Техническим результатом являются упрощение и усовершенствование конструкции подающего устройства рабочего органа, повышение точности выполнения распилов керна, снижение износа алмазного отрезного круга, а также расширение функциональной возможности станка для распиловки керна и снижение металлоемкости конструкции. Станок содержит рабочий стол с узлом крепления подлежащего резке керна горной породы, привод рабочего органа в виде алмазного отрезного круга и подающее устройство рабочего органа. Причем узел крепления керна выполнен с возможностью перемещения в двух взаимно перпендикулярных направлениях относительно рабочего стола, при этом распиливаемый керн з
