The invention discloses an efficient automobile parts polishing device. The efficient automobile parts polishing device comprises a frame body. Two sides of the bottom of the frame body are fixedly connected with support legs. The middle of the inner side of the frame body is fixedly connected with a separating plate. The front of the top of the inner side of the frame body is in threaded connection with a first screw rod. The top of the first screw rod passes through the top of a cavity of the frame body, and is extended to the exterior of the frame body. The efficient automobile parts polishing device is capable of, through cooperated use of the frame body, the first screw rod, a circular block, a hydraulic cylinder, a motor, a polishing sheet, a support plate, a top plate, a fixing block, a circular column, a magnet, a telescopic rod, a connecting rod, an inclined block, a first spring, a short block, a push rod, a pushing block, a fixing plate, a second spring, a pressing block, aslender rod, a thick rod, a semi-circular cylinder, a long rod, an inflating ring, a sponge mat and a magnet block, effectively fixing parts in different shapes, avoiding a condition that displacementhappens in a polishing process of the parts without artificially fixing the parts, and effectively protecting a worker.
