[0002] The explosion-proof shell of the monitor is integrally injection-molded, and wire drawing is likely to occur on the outer surface of the explosion-proof shell during the injection molding process, so the outer surface of the explosion-proof shell needs to be polished and ground. In the existing technology, for explosion-proof shells with irregular shapes, manual grinding is required, and the automatic grinding device cannot grind all the outer surfaces of the explosion-proof shell. When grinding manually, the worker needs to fix the explosion-proof shell with one hand and hold the grinding device with the other hand to grind the explosion-proof shell. During the grinding process, the worker also needs to turn the explosion-proof shell, thus reducing the grinding efficiency. Therefore, a grinding device for an explosion-proof shell that can improve the grinding efficiency is proposed. Summary of the Invention
