The invention relates to a structure adopting a
bevel gear set for driving four-sided
grinding heads. The structure is provided with a main rotating shaft, the main rotating shaft is installed on a gear box, one end of the main rotating shaft is connected with a
polishing motor, a main
bevel gear is arranged on the main rotating shaft in the gear box and meshes with the four auxiliary bevel gears, the auxiliary bevel gears are arranged on auxiliary rotating shafts, one ends of the auxiliary rotating shafts extend out of the gear box and are provided with the detachable
grinding heads, one surface of each
grinding head is provided with a disc-shaped
polishing disc, the other surface of each grinding head is provided with a connecting shaft, and the connecting shafts are installed on eccentric positions of the auxiliary rotating shafts. According to a
polishing head with the structure, the gear box is fixed on a turnover frame, the turnover frame is assembled on the main rotating shaft and is driven by a turnover motor to rotate, and one end of the main rotating shaft extends out of the gear box and the turnover frame to be connected with a polishing motor through a first
clutch. According to the structure and the polishing head with the structure, the polishing motor is far away from the polishing area, so that water and dust are prevented from entering the polishing motor, and the polishing motor is protected; and one motor can drive the multiple grinding heads, the structure is simple, manufacturing and assembling are convenient, and maintenance is convenient.
