Description
Technical field
The present invention relates to a kind of cutting-tool engineering field, more particularly to a kind of two swords taper ball head milling cutter.
Background technology
The milling cutter for milling tapered hole and with tapered deep hole can be with milling mould steel, cast iron, carbon steel, conjunction now
Jin Gang, tool steel and general iron material, there is cutting swarf when carrying out machining and be difficult to discharge and shake excessive defect in it,
Cutting swarf will decline the cutting ability ability of milling cutter by accumulating for a long time, and make milling cutter bite diminish with
Vibrations become big, cause the reduction of the efficiency of milling.
The content of the invention
The present invention is in order to overcome the shortcomings of that above-mentioned technical problem processes tapered hole conveniently there is provided one kind, and chip removal effect is good,
Tool sharpening surface is smooth, prevents that cutter from resonating with clamping device, so as to improve two sword tapers of cutter life length
Rose cutter.
The technical scheme for solving above-mentioned technical problem is as follows：
Two sword taper ball head milling cutters, including cutter head and handle of a knife, cutter head are arranged on handle of a knife lower end, cutter head provided with cutting edge and
Helical flute, the knife upper end offers annular groove and rectangular recess, and annular groove is communicated with rectangular recess, the knife
Head is cone, and taper is 10 °, and cutter head bottom is spherical, and the radius of sphere is 1.5mm, and spherical bottom is provided with locating slot, sphere
Provided with two cutting edges, cutting edge upwards, is equipped with helical flute, helical flute with conical surface spiral under cutting edge
Clear side is provided with, clear side is provided with ridge, anti-interference ladder is provided between the cutter head and handle of a knife, anti-interference ladder is circular cone
Shape, small one end of diameter is connected with cutter head, and the big one end of diameter is connected with handle of a knife, is set between anti-interference ladder and helical flute
Having be coated with silicon coating on dovetail transition part, cutter head.
Chip pocket is provided between the cutting edge of spherical bottom two, chip pocket is connected with the helical flute on circular cone.
The cutter head bottom to the distance at the top of helical flute be 13.5mm.
Using such scheme, two sword taper ball head milling cutters, knife upper end offers annular groove and rectangular recess, and annular is recessed
Groove is communicated with rectangular recess, and annular groove is engaged with rectangular recess with clamping device, it is therefore prevented that the milling cutter occurs when in use
The phenomenon skidded and shaken, cutter head is cone, and taper is 10 °, is conducive to processing taper groove and processes taper deep hole, cutter head bottom
Portion is spherical, and the radius of sphere is 1.5mm, and spherical bottom is provided with locating slot, is easy to be equipped with debris under positioning, cutting edge
Groove, helical flute is provided with clear side, and clear side is provided with ridge, is easy to chip removal, improves the surface smoothness of machined surface, ridge energy
The chip of spiral is cut off, prevents that chip from rolling up milling cutter, is unfavorable for being coated with silicon coating on milling cutter work, cutter head, improves milling cutter
Waterproof and corrosion resistant performance, improve the surface smoothness of milling cutter.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is schematic structural view of the invention.
Fig. 2 is schematic diagram of the present invention.
Embodiment
As illustrated, two sword taper ball head milling cutters, including cutter head 1 and handle of a knife 2, cutter head 1 is arranged on the lower end of handle of a knife 2, cutter head 1
Cutting edge 3 and helical flute 4 are provided with, the upper end of handle of a knife 2 offers annular groove 5 and rectangular recess 6, annular groove 5 and square
Connected in star 6 is communicated, and annular groove 5 is engaged with rectangular recess 6 with clamping device, it is therefore prevented that the milling cutter skids when in use
With the phenomenon of vibrations, cutter head 1 is cone, and taper is 10 °, is conducive to processing bellmouth or taper deep hole, and the bottom of cutter head 1 is ball
Shape, the radius of sphere is 1.5mm, mentions the cutting output of milling cutter, improves the intensity of the bottom of cutter head 1, prevents that cutter head 1 from bursting apart, spherical
Bottom is provided with locating slot, and sphere upwards, is all provided with provided with two cutting edges 3, cutting edge 3 with conical surface spiral under cutting edge 3
There is helical flute 4, helical flute 4 is provided with clear side 7, and clear side 7 is provided with ridge 8, is conducive to chip removal, improves machined surface
Surface smoothness, clear side 7 can cut into spiral helicine chip provided with ridge 8, prevent that chip from winding cutter, influence the work of cutter
Make quality, anti-interference ladder 9 is provided between cutter head 1 and handle of a knife 2, anti-interference ladder 9 is cone, the small one end of diameter and cutter head
1 connection, big one end of diameter is connected with handle of a knife, and anti-interference ladder 9 designs the processing space for further adapting to relatively deep and relatively narrower,
The generation of interference problem effectively is prevented, while adding tool motion space, is conducive to the establishment of numerical control program, anti-interference rank
Dovetail transition part 10 is provided between ladder 9 and helical flute 4, chip removal is improved, dovetail transition part 10 makes chip preferably discharge
Consider to be worth doing and silicon coating is coated with groove 4, cutter head 1, improve the waterproof and corrosion resistant performance of milling cutter, improve the surface smoothness of milling cutter.
It is preferred that, chip pocket is provided between the cutting edge 3 of spherical bottom two, chip pocket connects with the helical flute on circular cone
Connect, mention chip removal function, prevent that chip from crossing long-time volume in spherical bottom.
Further, the distance at the bottom of cutter head 1 to the top of helical flute 4 is 13.5mm, and the Design of length of chip area 4 is closed
Reason, is conducive to cutter chip removal.
The invention is not limited in described embodiment, those skilled in the art is not departing from the spirit i.e. public affairs of the present invention
In the range of opening, can still make some amendments or change, thus the scope that is limited using claims of the scope of the present invention as
It is accurate.
