Abstract
Изобретение относитс к станкостроению , в частности касаетс изготовлени инструмента , и может быть использовано дл восстановлени геометрических параметров изношенных буровых коронок. Цель изобретени - повышение производительности заточки. На направл ющих полозь х 3 корпуса установлены с возможностью перемещени сухарики 4, имеющие призматические симметрично расположенные рабочие поверхности, две соседние их которых образуют гнездо 6 дл размещени в них хвостовика 7 буровой коронки. Перемещение сухариков 4 и закрепление коронок производитс крепежным болтом 8, который ушир етс в подпорный уголок 9. В донных част х гнезд 7 размещены пружины 10. Дл установки затачиваемых лезвий коронок в одной плоскости и в одном направлении служит шаблон 12 с ограничительными направл ющими упорами 13. Конфигураци последних зависит от вида затачиваемых коронок. Заточка коронок производитс абразивным кругом 14, имеющим V-образный профиль. 10 ил. елThe invention relates to a machine tool industry, in particular, to the manufacture of a tool, and can be used to restore the geometrical parameters of worn drill bits. The purpose of the invention is to increase the sharpening performance. On the guides of the runners x 3, the bodies are mounted with the possibility of displacing the crunches 4, having prismatic symmetrically arranged working surfaces, two adjacent of which form a nest 6 for accommodating the core 7 of the drill bit 7. The movement of the croutons 4 and the fastening of the crowns is made by the fastening bolt 8, which widens into the retaining corner 9. Springs 10 are placed in the bottom parts of the sockets 7. Template 12 with restrictive guide stops 13 serves to install the crown cutters in the same plane and in one direction. The configuration of the latter depends on the type of the crowned crown. The sharpening of the crowns is made by an abrasive wheel 14 having a V-shaped profile. 10 il. ate
