Detailed description of the invention
Fig. 3 to Fig. 6 shows the rotary cutting tool embodiment of the first axial accurate positioning of the present invention, including rotating
Cutter hub 1, cutter holder 2, cutting tip 3, cutter holder securing member 4 and blade fastener 5, rotate cutter hub 1 be provided with by end locating surface 111,
The cutter groove 11 that first side-locating face 112 and the second side-locating face 113 surround, cutting tip 3 is fixed on cutter by blade fastener 5
On folder 2, the first side-locating face 112 is the face that cutter groove 11 is relative with the end cutting edge 31 of cutting tip 3, and cutter holder 2 is along rotating cutter hub 1
Be inserted radially into cutter groove 11, the first side-locating face 112 forms interference clamping position with end locating surface 111 to cutter holder 2, and cutter holder fastens
Cutter holder 2 and rotation cutter hub 1 are connected fixing by part 4.The interference clamping position of cutter holder 2 faced by the two of cutter groove 11 and cutter holder securing member 4
Connection to cutter holder 2 is fixed, this at two location structure be grouped together into cutter holder 2 is crossed location, this location structure
Make cutter holder 2 allow to move radially in cutter groove 11, strengthen the axle head impact resistance of cutting tool greatly and axially determine
Position precision, and this impulsive force shared by the first side-locating face 112 and end locating surface 111 greatly, cutter holder securing member 4
Only need to share the most at least part of impulsive force, effectively inhibit cutter holder securing member 4 to contact with cutter holder securing member 4 with rotating cutter hub 1
The deformation at place, thus improve the positioning precision to cutter holder 2 of cutter groove 11, and improve the safety of operation；Meanwhile, this mistake
Location structure can provide bigger moment of torsion for cutter holder 2, can the cutter holder 2 the most processed rotation in cutter groove 11 so that cutter groove 11
All the time it is in surface contact state with cutter holder 2, greatly reduces the load at the handing-over line outside cutter holder 2 and cutter groove 11, it is to avoid
Cutter groove 11 is deformed in this place or collapses scarce, thus extends the service life of cutting tool.
In the present embodiment, the first side-locating face 112 is provided with the second groove 1121, and the location end face of cutter holder 2 is provided with
Two raised lines 22, the second raised line 22 supports to be located in the second groove 1121, and the second groove 1121 and the second raised line 22 are parallel to location, the end
Face 111 is arranged, and is directed at the second groove 1121 by the second raised line 22 during installation, and cutter holder 2 radially pushes cutter groove 11, cutter holder 2
After loading, the second raised line 22 is limited by the second groove 1121, and cutter holder 2 is formed the location being perpendicular to end locating surface 111 direction,
With cutter holder securing member 4, cutter holder 2 and rotation cutter hub 1 are connected fixing afterwards, thus formed and crossing of cutter holder 2 is positioned, it is to avoid rotate
Load concentration suffered by cutter hub 1 is in cutter holder securing member 4 and the junction rotating cutter hub 1, and the load alleviating cutter holder securing member 4 is born
Load, this crosses that location structure is simple, easily realizes, easy for installation, accurate positioning；By the second raised line 22 and the second groove 1121
Cooperation, increase the contact area of cutter holder 2 end and cutter groove 11, it is provided that bigger frictional force carrys out balanced cutting toolsmith
Centrifugal force suffered by cutter holder 2 when making, thus alleviate the load burden of cutter holder securing member 4, reduce suffered by cutter holder securing member 4
Shearing force, extends the service life of cutter holder securing member 4；The quantity of the second groove 1121 and the second raised line 22 may each be multiple,
But require that the two quantity is equal.
The present embodiment is provided with the 3rd groove 1131 further on the second side-locating face 113, and the side, location of cutter holder 2 sets
Having the 3rd raised line 23, the 3rd raised line 23 supports to be located in the 3rd groove 1131, and the 3rd groove 1131 and the 3rd raised line 23 are perpendicular to rotation
Rotor body 1 axially arranged, by the 3rd groove 1131 and the cooperation of the 3rd raised line 23, can be positioned into the radial direction of cutter holder 2
Row is revised, to guarantee the radial direction accurate positioning of cutter holder 2；Meanwhile, the 3rd groove 1131 and the 3rd raised line 23 can axial with cutter holder 2
Size carries out certain correction, and, the 3rd groove 1131 and the 3rd raised line 23 also possess torsion proof ability, disperse further
Rotate cutter hub 1 institute loaded；The quantity of the 3rd groove 1131 and the 3rd raised line 23 may each be multiple, but requires the two quantity phase
Deng.
In the present embodiment, the second groove 1121 is by the second groove floor 1122 and is divided into the second groove floor 1122 both sides
The second groove side 1123 constitute, shape between the second groove side 1123 and the end locating surface 111 relative with end locating surface 111
Become opening towards the acute angle inside cutter groove 11, and cutter holder 2 formed interference clamping position, thus limit cutter holder 2 can only be at cutter
Move radially in groove 11；Second raised line 22 is convex be divided into the second raised line end face 221 both sides second by the second raised line end face 221
Bar side 222 is constituted, and the angle between two the second groove sides 1123 is β, the angle between two the second raised line sides 222
For β 1,30 °≤β≤160 °, 30 °≤β 1≤160 °, 5 '≤β 1-β≤3 °, the second raised line end face 221 and the second groove floor
Pretension gap it is provided with between 1122.When second raised line 22 loads, the second groove 1121 has certain deformation space, makes second recessed
Groove 1121 is deformed, and on the one hand this deformation makes cutter holder 2 obtain certain pretightning force, when cutter holder 2 is by the shadow of cutting force
Ringing and produce when reversing the trend, this pretightning force can balance the torsion that a part of cutter holder 2 is subject to, thus protects cutter holder further
Securing member 4, improves the safety of cutting tool；3rd groove 1131 is by the 3rd groove floor 1132 and is divided into the 3rd groove
3rd groove side 1133 of both sides, bottom surface 1132 is constituted, and the 3rd raised line 23 is by the 3rd raised line end face 231 and to be divided into the 3rd convex
3rd raised line side 232 of article end face 231 both sides is constituted, and the angle between two the 3rd groove sides 1133 is γ, two
Angle between three raised line sides 232 is γ 1,30 °≤γ≤160 °, 30 °≤γ 1≤160 °, 5 '≤γ 1-γ≤3 °, the
It is provided with pretension gap between three raised line end faces 231 and the 3rd groove floor 1132, in the present embodiment, β=γ=60 °, β 1=γ 1=
61°.The cutter groove 11 that the angle design of this groove and raised line makes the present invention rotate on cutter hub 1 can accommodate different size and profile
Cutter holder 2, cutting tool can be made simultaneously when cutting and there is identical positioning precision, during specific design, by convex during non-cutting
Bar is set to interference fit with the side of groove, and opposite side is set to matched in clearance, due to the rotation cutter hub 1 relatively cutter holder of cutting tool
2 have lower intensity and more preferable extensibility, cutter holder 2 make when loading raised line extruding groove to there being the side elastic deformation in gap,
Cutter holder 2 has certain pretightning force, under chip-load within the specific limits, equipped with cutting edge after having loaded when non-cutting
The cutter holder 2 of sheet 3 when cutting and has identical contour structure size during non-cutting, thus cutting tool is when cutting and Fei Qie
There is when cutting identical precision, make the design performance of cutting tool and actual performance form unification.In the present embodiment, the second groove
1121, the second raised line the 22, the 3rd groove 1131 and the 3rd raised line 23 are equipped with a plurality of, and adjacent projection can be with the change of confinement groove
Shape amount, thus avoid groove to produce plastic deformation as far as possible, make it the pretightning force that stable, lasting offer is enough.
