Fig. 1 shows a kind of wind electricity blade arrester screw installation punching guided tooling comprising: pedestal 100 and guiding
Component 200.Be provided on pedestal 100 both ends perforation V-groove 110, two sides of V-groove 110 be parallel to each other and with pedestal 100
Edge it is mutually close, the bottom of V-groove 110 is provided with the intercommunicating pore 120 of perforation.Guidance set 200 is fixed on pedestal 100, guiding
A pilot hole 221 is provided on component 200, pilot hole 221 is connected with intercommunicating pore 120, the evacuation pilot hole completely of intercommunicating pore 120
221, the axial direction of pilot hole 221 and the plane that two sides of V-groove 110 are formed are perpendicular.
Punching guided tooling is installed when drilling on the type face of wind electricity blade using wind electricity blade arrester screw, will be oriented to
Tooling is placed in punch position, and wherein the two of V-groove 110 side is bonded substantially with the type face of blade, 221 face leaf of pilot hole
Punch position on the type face of piece.At this point, the plane phase of two sides formation due to the axial direction and V-groove 110 of pilot hole 221
Vertically, the curved surface of the punch position of the axial direction and blade of pilot hole 221 is substantially vertical.Operator presses pedestal 100 in wind-powered electricity generation
