ACCELERATION HEAD Russian patent published in 2002 - IPC

FIELD: machine engineering, namely working in number program control machine tools parts of constructional steels and cast irons by means of hard-alloy, quick-cutting and abrasive tools, grinding cone surfaces in coordinate-grinding machine tools. SUBSTANCE: acceleration head includes cone stem, body-carrier with satellites mounted on axles, crown and sun gear wheels, output shaft with collet chuck and positioning unit. Intermediate plate is joined with cone stem and it has guides with cylindrical surfaces for joining with positioning unit by means of stopper having two springs. Balancing weight is arranged on guides. Crown gear wheel is joined (for arresting it) with stopper by means of above mentioned springs. Body-carrier is mounted in guides with possibility of angular displacement. Such head allows to change and regulate inclination angle of tool at working cone surfaces, to chamfer opening at both sides. EFFECT: enhanced quality and efficiency of working parts. 7 dwg
