Description
(54) УСТ;РОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ЗАДНЕГО УГЛА СПИРАЛЬНЫХ СВЕРЛ(54) MOUNT; SOLID FOR MEASUREMENT OF THE REAR ANGLE OF SPIRAL DRILLS
во втулку 1 и барашком 6 выбирают зазор между сверлом и втулкой, обеспечива , однако, свободное вращение сверла. Сверло довод т до осевого упора 2, после чего, перемеща каретку 4/ устанавливают наконечник измерител 5 линейных церемещений на тре Оуемый диаметр d измерени . Поворотом сверла подвод т режущую крсшку к упсм нутому наконечнику, после чего устанавливают измеритель на :нуль и с помощью барашка зак юпл ют угломерную шксшу 7 на сверле, обеспечива совпадение его нулевой отметки с указателем 10. Затем, поворачива сверло на заданный угол (tiaпример 10), отмечают падение затылка по измерителю линейных перемещений , &ВС ала которого (дл заданных диаметра d измерени и углового перемещени сверла) может быть градуирована непосредственно в величинах заднего угла.in the sleeve 1 and the wing 6 choose the gap between the drill and the sleeve, providing, however, the free rotation of the drill. The drill is brought to the axial stop 2, after which, moving the carriage 4 /, install the tip of the gauge 5 linear displacements on the three dimensional diameter d of the measurement. By turning the drill, the cutting lug is brought to the footed tip, then the gauge is set to: zero and with the help of a lid, the angle gauge 7 is mounted on the drill, ensuring that its zero mark coincides with the pointer 10. Then, turning the drill to the specified angle (tia example 10 ), note the drop in the neck by the linear displacement meter, & BC ala (for given diameter d of measurement and angular displacement of the drill) can be calibrated directly in the values of the back angle.
Величина заднего угла св зана с указанными параметрами соотнсн ениемThe magnitude of the rear angle is related to the indicated parameters by the relation

Описанное устройство позвол ет также определ ть величину разновысотности главных режущих кромок относительно друг друга.can be installed anywhere on the cutting edge. The described device also makes it possible to determine the magnitude of the difference in height between the main cutting edges relative to each other.
