ANGULAR ADAPTOR OF DRILL FOR DRILLING OPENINGS Russian patent published in 2003 - IPC

FIELD: machine engineering, namely drilling mounting openings at assembling procedures. SUBSTANCE: angular adaptor includes hollow body with mutually rotatable parts; placed in hollow body drive shaft and spindle for mounting and rotating drill; yoke for securing body to drill. In order to simplify design, to provide possibility for changing three-dimensional position of drill axis and to rigidly fix spindle by necessary angle, rotatable parts are in the form of two sleeves arranged one inside another and mounted inside hollow body with possibility of rotation relative to it. Each sleeve has opening whose axis is arranged in the same plane with axis of outer surface of body and it is inclined relative to it. Axis of opening of inner sleeve is inclined relative to axis of its outer cylindrical surface. Spindle is arranged in opening of inner sleeve. EFFECT: simplified design. 4 dwg
