Brief description of the drawings
Fig. 1 is the titanium alloy gear division special-purpose milling cutter schematic diagram that the present embodiment provides.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
The titanium alloy gear division special-purpose milling cutter schematic diagram that Fig. 1 provides for the present embodiment, described titanium alloy gear division special-purpose milling cutter
Including handle of a knife 1, handle of a knife 1 couples cone 2 by stage casing and is connected with empty avoiding necking down 3, and the end of empty avoiding necking down 3 is provided with all sword helicla flutes
Cutting edge 4, the end of cutting edge 4 of all sword helicla flutes are provided with arc ball knife face 5.Arc ball knife face 5 is bulb shape, at the top of bulb
It is centrally formed shear blade 6.Cutting edge 4 of the shear blade 6 by the transition circle of arc ball knife face 5 to all sword helicla flutes.
The overstriking of handle of a knife 1, handle footpath size are 6mm, increase its intensity.
The cone angle of stage casing connection cone 2 is 20 °~30 °.
The diameter of empty avoiding necking down 3 is smaller 0.08mm~0.2mm than the diameter of the cutting edge 4 of all sword helicla flutes.
All sword helicla flutes are bound to each other to form by groove and the Parabolic groove back of the body.
The cutting edge 4 of all sword helicla flutes is designed to that twolip is spiral, and all angles of sword helicla flute 41 are 26 ° -36 °, all sword spiral shells
The core thickness a diameter of 63%~68% of spin slot 41, the groove anterior angle of all sword helicla flutes 41 is 12 °~16 °.
All sword helicla flutes 41 are connected with arc ball knife face 5, and all sword helicla flutes 41 form sphere with the joining place of arc ball knife face 5
The circle arc support back of the body 51.
The cutting edge 4 of all sword helicla flutes has an arc eccentric formula relief angle, the angle of the arc eccentric formula relief angle for 9 °~
13°。
Arc ball knife face 5 has two relief angles, and the relief angles of sphere one are 11 °~14 °, and the relief angles of sphere two are 25 °~
30°。
Arc ball knife face 5 has rake face, and rake face top angle is 2 °~6 °, and rake face rear angle is 6 °~10 °.
According to the functional character of gear division equipment, cutter first must be able to allow equipment to install identification automatically in equipment.Gear division
Equipment carries installation tool function, as long as cutter is placed on the socket specified, gear division equipment just energy automatic tool changer, but must cutter
Itself there is guide effect, not so gear division equipment can not be going on Cutting tool installation manner to main shaft.Therefore, according to the Intensity Design of cutter,
The handle of a knife 1 of this titanium alloy cutter is designed to a diameter of 6mm reinforcement handle.The shank of handle of a knife 1 has the chamfering of 3mm × 60 °, this angle
Degree is exactly guide angle 11.Gear division equipment is according to the guide angle of 60 ° of shank being gone on Cutting tool installation manner to main shaft.
Gear division equipment simultaneously have carry measurement length the infrared measurement machine, but must cutter carry locator card in itself, because
This sets positioning ring 12 at the middle part of handle of a knife 1, and the infrared measurement machine calculates length and the installation of knife by positioning ring 12
Position degree, carry out tool offset compensation.
In order to which converted products is more stable, the fraction defective of product is reduced, the blade of cutter is ball-type, can so be reduced
The a large amount of cuttings simultaneously of the other positions of cutter.Gear division equipment is 5 axle linkage motion cuttings, and when processing inner concave, cutter must be designed to
Empty avoiding type, mainly the diameter behind cutting edge is reduced, avoid sword rear end from interfering with product, produced cutting edge and fracture.
So neck size must be reduced after control sword length, while it must also consider the rigid of cutter, therefore empty avoiding necking down 3 is straight
Footpath is designed as smaller 0.08mm~0.2mm than the diameter of the cutting edge 4 of all sword helicla flutes.So it is possible to prevente effectively from interfering, simultaneously
The rigidity of cutter is not lost yet.
Designed by cutting-tool angle, and coordinate the function of gear division equipment, this utility model cutter possesses in gear division equipment
On machining function, rational guide angle, accurately positioning ring, effectively keep away interference.High-precision spherical design processing, makes
The product quality of processing is more stable, and scrappage is lower, and cutting-tool's used life is longer.And the similar cutter of in general is at all can not
It is provided in gear division equipment, cutter provided by the utility model is the model for gear division titanium alloy tooth for being adapted to gear division equipment
The special-purpose milling cutter of processing.
In addition, nano coating processing is carried out in cutter matching surface, to strengthen the wearability of cutter.Reduce friction simultaneously
Coefficient so that cutter has longer service life.
