Abstract

Использование: дл  закреплени  заготовок при механической обработке. Сущность изобретени : торцы 4 барабана 2 выполнены коническими. На барабане 2 и его торцах 4 выполнены сквозные продольные пазы, образующие упругие элементы 6 на барабане и упругие элементы 7 на торцах 4. У основани  торцов 4 выполнены полукруглые кольцевые канавки 8. Заготовку устанавливают на оправке за счет упругой деформации торцов. Если диаметр заготовки несколько больше размера диаметра барабана 2, то после установки на него заготовки пинолью задней бабки станка надавливают на нажимной элемент 3. Происходит деформаци  упругих элементов 7 торцов 4, а в районе полукруглых канавок 8 - упругий изгиб. Упругие элементы б барабана 2 разожмутс  в радиальном направлении и произойдет крепление заготовки, 2 ил.Usage: for fixing workpieces during machining. SUMMARY OF THE INVENTION: The ends 4 of the drum 2 are conical. On the drum 2 and its ends 4, through longitudinal grooves are made, forming elastic elements 6 on the drum and elastic elements 7 on the ends 4. At the base of the ends 4 there are semicircular annular grooves 8. The blank is installed on the mandrel due to the elastic deformation of the ends. If the diameter of the workpiece is slightly larger than the diameter of the drum 2, then after installing the workpiece with the pin of the tailstock of the machine, press on the pressing element 3. The elastic elements 7 of the ends 4 are deformed, and elastic bending occurs in the region of the semicircular grooves 8. The elastic elements b of the drum 2 will be unclenched in the radial direction and the workpiece, 2 sludge, will be fixed.
