The connecting plates are provided with a sliding groove, and the sliding groove is connected with a sliding rod. The bottom of the sliding rod is provided with a third transmission mechanism, and the bottom of the third transmission mechanism is welded with a motor. The output end of the motor is coaxially connected with a polishing disc. The inside of the sliding rod is provided with a cavity for horizontal sliding of the third transmission mechanism. The cavity is provided with a second transmission mechanism. The first transmission mechanism is arranged between the sliding rod and the baffle.

The fourth transmission mechanism, the fifth transmission mechanism, and the first and second limiting plates clamp the cast iron piece to prevent it from moving during polishing.

[0004] During the polishing process of the above-mentioned patent, when one face of the cast iron piece is polished and the other face needs to be polished, the clamping of the cast iron piece needs to be released first, and the other face to be polished of the cast iron piece needs to be turned over to be opposite to the position of the polishing head. Then the cast iron piece can be clamped and fixed by the clamping piece before the polishing of the other face of the cast iron piece can be carried out. If the six faces of the cast iron piece need to be polished, the worker needs to repeat the above-mentioned operation five times.
