Compensation mechanism for automatically detecting cutter abrasion for quartz crucible trimming and chamfering machine

The utility model discloses a compensation mechanism for automatically detecting cutter abrasion for a quartz crucible trimming and chamfering machine. The device comprises an edge cutting/inner edgechamfering mechanism, an outer edge chamfering mechanism, a cross-shaped sliding table, a displacement sensor, an air cylinder and a controller. The edge cutting/inner edge chamfering mechanism and the outer edge chamfering mechanism are sequentially arranged on a moving sliding table of the cross-shaped sliding table module in parallel from top to bottom and are driven by the cross-shaped slidingtable module. The edge cutting/inner edge chamfering mechanism comprises a cutter arranged on an edge cutting/inner edge chamfering shaft, the air cylinder is arranged on the edge cutting/inner edgechamfering mechanism, the telescopic direction of the air cylinder is the same as the sliding direction of the moving sliding table, the displacement sensor is connected with the air cylinder and arranged in the telescopic dire
