In the invention, the square positioning block 2 is cast on the blade body 11 to change the special-shaped blade body 11 into a regular square shape, thereby reducing the difficulty of subsequent positioning and clamping, shortening the clamping time and accelerating the processing and manufacturing efficiency. The square positioning block 2 is provided with the steps, after casting is completed, only the high step surface 21 needs to be subjected to finish machining, the precision of the high step surface 21 is guaranteed, the size of the square positioning block 2 is reduced, materials are saved, meanwhile, the finish machining area is reduced, and the machining efficiency is accelerated.
Further, a stator blade 1 processing method and clamping tool include: the positioning device comprises a base 3, supporting blocks 4, a positioning cushion block 5, a pressing block 6, a Y-direction positioning block 7 and an X-direction positioning block 8, wherein the positioning cushion block 5 is arranged on the base 3, the X-direction positioning block 8 is arranged on one side of the positioning cushion block 5, and at least two supporting blocks 4 are arranged on the other side of the positioning cushion block 5; the square positioning block 2 is placed on the positioning cushion block 5, and a compression screw 9 is arranged on the supporting block 4; the Y-direction positioning block 7 is matched with the fine positioning step surface 22; the pressing block 6 can press the square positioning block 2 in the Z-axis direction.
