Description
Technical field
The present invention relates to a kind of milling cutters, and in particular to a kind of band edge tooth thread milling cutter.
Background technique
Component of the Milling Machining in field of machining is becoming more and more important, and gradually takes to a certain extent
It is for Milling Process, the rotary cutter with one or more cutters tooth, work for other processing methods, milling cutters such as vehicle, brills
Each cutter tooth successively intermittently cuts the surplus of workpiece when making, milling cutter be mainly used for processing on milling machine plane, step, groove, at
Shape surface and cutting workpiece etc..With the development of numerical control processing, present numerical control screw thread milling is achieved, and is milled in numerical control screw thread
Need to use the milling cutter of special processing screw thread when cutting.And the existing not set end tooth of screw cutter, milling thread bottom outlet and screw thread
When processing need to first with bore thread Pilot hole Tool in Milling thread Pilot hole, then just use screw cutter milling thread hole, need frequently with
Tool changing tool, is inconvenient；And the lip height on all teeth is consistent, not can be carried out while coarse-fine processing, reduces the longevity of cutter
Life.
Summary of the invention
In view of the above-mentioned problems, the object of the present invention is to provide one kind can be realized milling thread bottom outlet, screw thread process one
Secondary molding, and the band edge tooth thread milling cutter that cutter life is high.Specific technical solution is as follows:
A kind of band edge tooth thread milling cutter, it is equal along its circumferencial direction on cutter head including knife handle and the cutter head that knife handle left end is arranged in
It is even to be equipped with multiple all teeth；Chip space is equipped between adjacent week tooth；Multiple screw chasing swords are designed on every all tooth；All screw threads
The top line left end of cutting edge tilts and right end is horizontal, and the angle between line left end and line right end is that obtuse angle (is analogous to height
Low buckle structure)；It is equipped with end tooth in cutter head left end, the end tooth periphery is equipped with multiple blades, and end tooth diameter is less than or equal to all teeth
The diameter of left end.
Further, on all teeth two screw chasing sword of arbitrary neighborhood all equal (i.e. two screw thread of arbitrary neighborhood of spacing
The axial distance that cutting edge corresponds to point-to-point transmission on middle line is all equal), the width of screw chasing sword is also identical.
Further, the quantity of the end tooth upper knife edge is three, four or five.
Further, the angle between adjacent thread cutting edge is 60 ° ± 15 '.
Further, on all teeth screw chasing sword all trapezoidal structure in section, the width at the top of screw chasing sword
It gradually becomes smaller from left to right.
Further, all tooth screw chasing sword height of left end first are all tooth right end screw chasing sword height three
/ mono-, the screw chasing sword height of all tooth left ends second is all tooth right end screw chasing sword height 2/3rds.
Further, the width at the top of all tooth right end screw chasing swords is equal to adjacent two screw chasing sword spacing
1/8th.
The present invention has the advantages that
(1) cutting way of band edge tooth thread milling cutter of the present invention is interrupted cut, and cutting the iron filings come is short bits, this
The threaded hole surface quality that processing method processes is good, and will not be damaged because of cracking of cutter to workpiece, for diameter
Efficiency is 2~3 times of screw tap for biggish threaded hole.
(2) in the interrupted cut of regular screw threads milling cutter, cut the iron filings come is band edge tooth thread milling cutter of the present invention
End tooth is increased on the basis of the features such as short bits, the one-pass molding of milling thread bottom outlet, screw thread process may be implemented, and end tooth can
With direct milling thread bottom outlet, and then milling thread hole, this cutter can save auger shell line bottom to the screw chasing sword of right end
The cutter in hole and simplified processing technology.
(3) all teeth have done the design for being analogous to height button, can carry out coarse-fine processing (left end on all teeth in process
Screw chasing sword carries out roughing, and the screw chasing sword of right end is finished), effectively raise the service life of cutter.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of band edge tooth thread milling cutter of the present invention；
Fig. 2 is the partial sectional view of screw chasing sword on all teeth in a kind of band edge tooth thread milling cutter of the present invention；
