Hard alloy blade polishing tool

The invention is suitable for the technical field of metal processing, and provides a hard alloy blade polishing tool which comprises a fixed seat, a mounting frame is fixed to the fixed seat, a lifting mechanism used for controlling a movable seat to ascend and descend is mounted on the mounting frame, and a rotating seat is mounted in the movable seat. An adjusting assembly used for adjusting the transverse position of the polishing assembly is further mounted on the mounting frame, and the rotating assembly is connected with the rotating seat; and the fixing mechanism comprises a movable seat, a driving assembly, a control piece, a fixing assembly and a limiting seat. According to the hard alloy blade polishing tool, through the mode that the polishing assembly is matched with the adjusting assembly, the lifting mechanism, the rotating assembly and the fixing mechanism, under the condition that the annular alloy blade is fixed at a time, a tool edge on the periphery of the annular alloy blade can be fully
