Description
Technical field
The utility model is related to machining equipment technical field, more particularly, to a kind of tapping machine.The utility model is also
It is related to a kind of automatic tapping machine with above-mentioned tapping machine.
Background technology
Tapping is a kind of method using screw tap machining internal thread.Traditional tapping method is that spiral shell is first processed on part
Line bottom outlet simultaneously processes chamfering at aperture.By Workpiece clamping, by screw tap to the aperture of its quasi- thread Pilot hole.Screw tap application is prolonged
The axial pressure in hole simultaneously rotates screw tap, and during hand tapping, rotation screw tap is using twisting hand.Screw tap incision workpiece 1 to 2 is first allowed to enclose,
Then take out screw tap inspection simultaneously correct, when screw tap cutting into position it is consistent with the center line in hole as far as possible.It is opened after correction
Begin complete tapping process.Above-mentioned craft tapping is more demanding to the technical merit of worker, in order to improve production efficiency, tapping machine
Occur.
