The invention relates to a driving device for a swinging
grinding head. The driving device for the swinging
grinding head is characterized by comprising a
machine shell. The
machine shell is shaped like a cylinder with a closed end and an open end, and a covering plate is arranged at the open end of the cylinder. The closed end of the
machine shell and the covering plate are both provided with central holes. A main shaft is arranged in the machine shell and penetrates through the central hole of the closed end of the machine shell and the central hole of the covering plate. A motor
stator is fixed to the inner wall of the machine shell. A motor rotor is fixed to the section, inside the machine shell, of the main shaft. A supporting seat is fixed to the outer side of the closed end of the machine shell. The section, on the outer side of the closed end of the machine shell, of the main shaft is rotationally matched with the supporting seat through a bearing. The end, corresponding to the covering plate, of the main shaft is connected with an
encoder, the
encoder is connected with a
servo driver through a wire, and the
servo driver is connected with a power source through a wire. The driving device is used for driving the swinging
grinding head to carry out ultra-accurate grinding
machining, equipment vibration is small, the angle adjustment is accurate, the grinding speed is high, the problems of
crawling and inching are avoided, the
machining accuracy of workpieces is high, and the maintenance cost of a mechanism is low.
