The invention relates to an intelligent grinding mold for a lithium battery, comprising a supporting bottom plate, a grinding device, and a fixing device, wherein the grinding device is mounted on thetop of the left end of the supporting bottom plate, and the fixing device is mounted on the top of the right end of the support bottom plate. The grinding device comprises a grinding side plate, a grinding motor, a grinding rotating plate, a grinding chute, a grinding carriage, a grinding push rod, and a grinding mechanism. The fixing device comprises a fixing plate, a clamping mechanism, an electromagnet ring, an extrusion telescopic rod, a pressing spring, an extrusion body, a limiting mechanism, and a fixing pillar. According to the intelligent grinding mold for lithium battery, the problems such as the lithium battery cover cannot be fixed for the structural characteristics when grinding the existing lithium battery cover, different types of covers require different fixtures, manual adjustment of the position of the grinding block is required when grinding different types of covers, and the grinding effect of the lithium battery cover is poor can be solved.
