Description

При таком положений по вл етс тенденци сдвига детали по опорной плос140сти ложемента. Дл предотвращени этого на плите-ложементе 5 нарезаны упорные зубцы 9, создающие преп тствие возможному сдвигу детали. Вершины зубцов 9 направлены в сторону, противоположную направлению усили прижима.At such positions, the part tends to move along the bearing surface of the cradle. In order to prevent this, stop teeth 9 are cut on the support plate 5, creating an obstacle to the possible movement of the part. The tops of the teeth 9 are directed in the direction opposite to the direction of the pressing force.
