Description
Technical field：
The utility model is related to screw tap, tapping devices, more particularly to shape small or accurate thread pitch of holes multistation
Screw tap, the tapping device of threaded hole.
Background technology：
Existing screw tap is clamped or is held windeisen clamping using drill chuck and carries out tapping.The structure of screw tap includes top
Square or hexagonal prism body clamping part, screw tap bar portion, the threaded hole forming section of tapping.If necessary to carry out multiple spiral shells
Pit shaping, a kind of method is individually to process in each hole to complete tapping.In order to ensure the tapping precision of each threaded hole, especially
Precise Distance between its each hole position or threaded hole position, through the digital control processing mode frequently with numerically-controlled machine tool, is sequentially completed each
The tapping process in hole.Another method is in order to improve the processing efficiency of multistation hole internal thread, frequently with similar to Ni Zhifu drill
Mode processed while multistation screw thread.When existing mechanical system carries out tapping, screw tap is all pressed from both sides using drill chuck
Fixation is held, and using drill chuck screw tap is driven to rotate, workpiece is cut or extrusion process form thread.Using existing
Multiple screw taps processing method, since each screw tap is all corresponding with a drill chuck, two adjacent holes that can be processed
Pitch of holes is the sum of radius that cannot be below two drill chucks；For between the hole of some small pitchs of holes or two adjacent holes
During the sum of radius away from less than two drill chucks, the tapping processing method of existing similar gang drill or multi-hole drill can not be used.For
The hole of the such shape of processing, can only carry out tapping processing by several times.In addition, no matter by the way of numerically-controlled machine tool tapping, still adopt
With porous tapping process, the positional precision in hole is completing rather than actual according to screw tap by the positioning of lathe drill chuck
For Working position come what is positioned, the hole that is processed position distance remains error amount, does not still ensure that between each threaded hole position
The precision of distance.It is theoretically vertical under screw tap clamps in drill chuck, it is vertical with processing plane, but can there are deviation,
So as to influence the machining accuracy of screw thread.
Utility model content：
The purpose of this utility model is to provide a kind of new screw taps, it may not be necessary to be completed by the clamping of drill chuck
Tapping works；Realize the tapping work of the porous bit synchronization threaded hole of small pitch of holes；Realize that accurately tapping is processed, while silk
