Pulse valve seat stud rapid positioning die

A pulse valve seat stud rapid positioning die capable of rapidly positioning a welding stud comprises an annular die body, six half-kidney-shaped round holes are symmetrically distributed in the edge of the annular die body, the included angle between the circle centers of every two adjacent half-kidney-shaped round holes and the connecting line of the circle center of the annular die body is 60 degrees, the diameter of an inner ring of the annular die body is equal to that of a pulse valve hole in an ash removal gas storage tank, the circle centers of the six half-kidney-shaped round holes correspond to the circle centers of six screw holes in the pulse valve seat in a one-to-one mode and are overlapped with the circle centers of the six screw holes in the pulse valve seat, an annular dent is carved in the annular die along a circle formed by connecting lines of the circle centers of the six half-kidney-shaped round holes through a metal nicking tool, the circle centers of the six half-kidney-shaped round ho
