AUTOMATIC LATHE FOR UNDERCUTTING ELECTRICAL MACHINE COMMUTATORS Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: lathe has bed, commutator turning drive, cutting tool, optical sensor, and control system. Novelty is that lathe is provided, in addition, with servo drives incorporating position detectors and play-free coupling. Two drives function to displace lathe carriage along two coordinates in horizontal plane and one drive, to turn commutator by means of coupling. Carriage mounts turret and optical sensor. One input of control system is connected to optical sensor and each of three other inputs, to position detector of one of servo drives. Three outputs of control system are coupled to electric motors of servo drives, fourth and fifth outputs, to cutting tool and turret. EFFECT: improved precision and quality of finishing commutators of all sizes, enlarged functional capabilities due to combining turning, undercutting, and grinding operations. 2 cl, 2 dwg
