Abstract

Изобретение относитс к машиностроению и может быть использовано дл поджима изделий со скошенным торцом или пустотелых изделий со скошенным торцом или эксцентричным закреплением, например , на токарных станках. В корпусе 1 на подшипниках установлены конический хвостовик 2, вдоль оси которого на корпусе 1 выполнены направл ющие 3, в которых установлены кулачки 4 с наклонными поверхност ми 5. Кулачки 4 дополнены стенками 7, внутренние поверхности 9 которых выполнены наклонными, совпадающими с наклонами рабочих поверхностей 5. Внутренние поверхности 9 стенок 7 с корпусом образуют полость, D которой расположен шар 10, взаимодействующий с корпусом 1 и внутренними поверхност ми 9 стенок 7, обеспечива самоустановку кулачков. 2 з.п. ф-лы, 6 ил.The invention relates to mechanical engineering and can be used to press products with a beveled butt or hollow products with a beveled butt or eccentric fastening, for example, on lathes. In the housing 1, bearings have a tapered shank 2, along the axis of which, guides 3 are made on the housing 1, in which the cams 4 with inclined surfaces 5 are mounted. The cams 4 are supplemented by walls 7, the internal surfaces 9 of which are inclined, coinciding with the inclinations of the working surfaces 5. The inner surfaces 9 of the walls 7 with the housing form a cavity, D of which is located the ball 10, which interacts with the housing 1 and the inner surfaces 9 of the walls 7, ensuring the self-alignment of the cams. 2 hp f-ly, 6 ill.

Claims

Claim

1. The rotating center, comprising a housing with a shank, in the axial guides of which cams with inclined working surfaces are installed, characterized in that, in order to expand technological capabilities by attaching thin-walled parts of various sizes, the device is equipped with additional cams, the outer surfaces of which coincide with similar surfaces main cams, and internal cams are made inclined, forming a cavity intended for <placement of a ball, citing with the end of the housing.

2. The center according to claim 1, characterized in that the angle between the inner surfaces of the walls of two opposite cams is 85-95 °.

3. The center according to claim 1, with the fact that the distance along the surface of the housing between the diametrically located cams is 1.5-1.7 times the diameter of the ball ..
