Abstract
Изобретение относитс к станкостроению и ,в частности, к устройствам дл закреплени заготовок на шпинделе станка. Целью изобретени вл етс повышение точности путем уравновешивани прецессионного колеса патрона. В корпусе 1 размещена прецессионна передача, выполненна в виде прецессионного колеса 3 и приводного вала 2 с торцовой эксцентричной поверхностью 11, взаимодействующей через шарики 12 с колесом 3. Колесо 3 св зано со спиральным диском спирально-реечного механизма перемещени кулачков. Вал 2 имеет также наружную эксцентрическую поверхность 13, дл взаимодействи со ступицей 14 противовеса, спицы 16 которого оснащены грузами 15. Поверхности 11 и 13 расположены так, что центры масс грузов 15 и колеса 3 всегда наход тс по разные стороны от оси вращени патрона. Таким образом, смещение колеса 3 сопровождаетс смещением противовеса, и патрон находитс в уравновешенном состо нии. 4 ил.The invention relates to a machine tool industry and, in particular, to devices for securing blanks on a machine spindle. The aim of the invention is to improve accuracy by balancing the precessional cartridge wheel. The housing 1 contains a precession gear, made in the form of a precession wheel 3 and a drive shaft 2 with an end eccentric surface 11, interacting through the balls 12 with the wheel 3. Wheel 3 is connected with the spiral disk of the helical-cam mechanism for moving the cams. The shaft 2 also has an outer eccentric surface 13 for interacting with the hub 14 of the counterweight, the spokes 16 of which are equipped with weights 15. The surfaces 11 and 13 are arranged so that the centers of mass of the weights 15 and the wheels 3 are always on opposite sides of the axis of rotation of the cartridge. Thus, the displacement of the wheel 3 is accompanied by the displacement of the counterweight, and the cartridge is in a balanced state. 4 il.
