Abstract
A grinding swing mechanism of a fine grinding machine comprises a box body, two power rotating shafts and an even number of swing rotating shafts. The swing rotating shafts are divided into two groups, and each group of swing rotating shafts correspond to one power rotating shaft. The head portions of the power rotating shafts extend out of the box body and are connected with a driving mechanism. An eccentric shaft is arranged on the end face of the tail portion of each power rotating shaft in a protruding mode. The central axis of the eccentric shaft on one power rotating shaft is located above the central axis of the power rotating shaft, and the central axis of the eccentric shaft on the other power rotating shaft is located below the central axis of the power rotating shaft. Swing connecting rods are arranged between the swing rotating shafts and the eccentric shafts, corresponding to the swing rotating shafts, on the power rotating shafts, and one end of each swing rotating shaft extends out of the box body and is provided with a grinding head. According to the structure, the even number of grinding heads are divided into two groups in the swinging process and the two groups of grinding heads swing in the opposite directions through the reasonable arrangement of the power rotating shafts and the swing rotating shafts, the two groups of grinding heads move either close to each other or away from each other, and thus resonance will not be generated between the grinding heads, and product quality is greatly improved.
