An automobile rear-view mirror three-dimension profiling edge
grinding machine comprises a
machine tool, a pneumatic transmission control part, a fixed-axis rotation part, a rotation part and a cooling liquid addition part. The fixed-axis rotation part comprises a motor II, a
cycloid needle wheel type
reducer, a profiling, a locating profiling, an upper rubber base and a lower rubber base, wherein the motor II is connected with the
cycloid needle wheel type
reducer, drives the profiling, the locating profiling and the lower rubber base to rotate around a fixed shaft through a gear, and drives a workpiece which is clamped between the upper rubber base and the lower rubber base to rotate around the fixed shaft. The rotation part comprises a motor I, a
rocker arm, a
grinding wheel, a guide wheel mechanism, a
cam-type mechanism and an elastic air cylinder, wherein the
cam-type mechanism is circular-arc-shaped cylinders with different heights, and the circular-arc central axis of the circular-arc-shaped cylinders and the rotation center of the
rocker arm coincide when the circular-arc-shaped cylinders are installed. When the profiling rotates by a circle, the
rocker arm swings one time back and forth at the left-right limit position, the included angle theta between the rocker arm and the AO direction finishes a periodic change, the rotating workpiece G is wrapped for one circle by the
grinding wheel, and the three-dimension grinding
machining of an automobile rear-view mirror is finished.
