Abstract

Изобретение относитс к станкостроению , используетс дл токарной обработки тел вращени одновременно с двух сторон. Целью изобретени вл етс повышение производительности станка за счет автоматического центрировани заготовки относительно общей линии центров станка при смене внутренних поверхностей базировани на наружные. Станок с центральным приводом содержит станину 1 с направл ющими , центральный привод 2, суппорты, центровые бабки, зажимной патрон 8 с основными 19 и перемещаемыми 21 по ним зажимными кулачками. Зажимной патрон 8 содержит средства дл перемещени дополнительных зажимных кулачков 21 по основным кулачкам 19, выполненные в виде упругих элементов, встроенных в корпус каждого кулачка 19, а средство дл фиксации зажимных кулачков 21 выполнено в виде составных т г 23 - 25 с сочленени ми, например, шарнирного типа, наход щихс под посто нным воздействием упругих элементов 26. 5 ил А-А л ЈThe invention relates to a machine tool, used for turning turning bodies of rotation simultaneously from two sides. The aim of the invention is to increase the productivity of the machine by automatically centering the workpiece relative to the general line of the centers of the machine when changing the inner surfaces of the base to the outer ones. The machine with a central drive contains a frame 1 with guides, a central drive 2, calipers, center heads, a clamping cartridge 8 with main 19 and movable 21 clamping cams along them. The clamping chuck 8 contains means for moving additional clamping cams 21 along the main cams 19, made in the form of elastic elements embedded in the body of each cam 19, and the means for fixing the clamping cams 21 are made in the form of composite bars 23-23 with joints, for example , hinged type, under constant influence of elastic elements 26. 5 il A-A l Ј

Claims

Claim

A lathe for processing internal and external surfaces of parts, comprising calipers and center heads mounted on the machine bed on two sides of the central drive spindle and clamping chucks built on the ends of the spindle of the central drive with additional clamping jaws with means moving independently of each other and means fixation of each of them on the main, characterized in that. what. in order to increase productivity due to automatic centering of the workpiece relative to the common line of machine centers when changing internal to external base surfaces, each of the clamping chucks is equipped with means for moving additional clamping cams along the main in the direction of the center line, made in the form of elastic elements built into the body of each from the main cams, and each means of fixing additional clamping cams is made in the form of controlled and under constant air ystviem elastic elements sticking.
