A kind of processing method of blast pipe axial direction screw, comprises the following steps：
The annular boss of installing plate is inserted to the pinching end of blast pipe so that annular boss is formed to the inwall of blast pipe A,
Support；Each fishbolt is screwed into corresponding positioning screw hole so that the outer wall that the light bar segment of fishbolt is close to blast pipe is set,
So that annular boss and fishbolt fix to the pinching end of blast pipe.
B, installing plate is fixed on the horizontal slide rail of machining tool so that the axial direction of blast pipe it is horizontally disposed, it is necessary to plus
The blast pipe of work axial direction screw is processed end end face and set towards the drill bit of machining tool, and the axial screw processed as needed
Position adjustment bit location so that drill bit is directed at axial screw present position.
C, installing plate is moved horizontally so that blast pipe moves to drill bit, startup drill bit is corresponding in the end face at blast pipe processing end
The thread Pilot hole of positioning screw hole is processed on position.
D, fishbolt is unloaded, the pinching end of blast pipe is separated with installing plate；Processed using screw tap on thread Pilot hole
Shaft is to screw.
When needing all to process axial screw at the both ends of blast pipe, pinching end, processing end are exchanged and repeated the above steps i.e.
Can.
Technique effect：（1）This blast pipe axial screw hole machined fixture, relative to prior art, to blast pipe
In process, it is clamped without the processing end to blast pipe so that when not deforming upon radially, and processing during processing only
It is axially to be squeezed, avoids and machine heel row tracheae resilience, the processing especially suitable for thin-wall stamping part；（2）Use
Annular boss and fishbolt position to blast pipe, are easily assembled, and connection is firm, by installing plate to blast pipe during processing
End face is supported, uniform force；（3）Installing plate uses aluminium sheet, and annular boss uses aluminium ring, and light weight, hardness is low, and reduction makes
To the scuffing of blast pipe during, and it is easy to process；（4）The screw front end of fishbolt is arranged to light bar segment, places and scratches
The outer surface of blast pipe.
