Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of annular chamfering bit milling cutter, including handle of a knife 1, the knife of cutter head 2 and first
44 4 tooth 41, the second cutter tooth 42, the 3rd cutter tooth 43 and the 4th cutter tooth cutters tooth；The front end of cutter head 2 offers cylinder vertically
Shape conduit 3, four cutters tooth are uniformly arranged with sequentially arranging successively around the cylindrical outside of conduit 3, and each cutter tooth front end is respectively provided with
There is blade, chip area 9 is provided between each cutter tooth；Four cutters tooth are used to bore mill annular groove, and chip area 9, which is used to discharge, bores mill
The chip to get off, avoids chip from blocking.
When specifically used, first, by the clamping of handle of a knife 1 on milling machine, adjustment cutter tooth contacts with machined surface；Then, rotating should
Annular chamfering bit milling cutter, cutter tooth start to be processed annular groove；Finally, cutter tooth is constantly polished annular groove, meanwhile, chip area 9
Constantly the chip polished is discharged, disposably completes the processing to annular groove.
In order to improve processing efficiency and crudy, the end face of the first cutter tooth 41 and the end surface shape phase of the 3rd cutter tooth 43
Together, formed by outer cutting face 5 and the oblique face 6 in the outer inner side of cutting face 5 that is arranged on；The end face of second cutter tooth and the 4th cutter tooth
End surface shape it is identical, formed by interior cutting face 7 and the outer oblique face 8 for being arranged on the outside of interior cutting face 7, the blade difference
It is arranged on outer cutting face 5 and interior cutting face 7；In use, outside in cut surface is entered by interior cutting face 7 and outer cutting face 5
Row is alternately polished, and due to polishing narrowed width, is alternately left polishing breach, is substantially reduced polishing resistance；Meanwhile interior oblique face
6 can be guided and smoothly be discharged in the outer inner side chip of cutting face 5, and outer oblique face 8 can be guided in the interior outside chip of cutting face 7
Smoothly discharge, chip obstruction milling cutter is avoided to rotate, so as to improve processing efficiency and quality.
It can be appreciated that when the slope in inside and outside oblique face is too small, chip removal will be caused to have some setbacks, easily block, when slope is excessive,
Cutting resistance can become big, stock-removing efficiency can reduce；Preferentially, the angle between interior oblique face 6 and outer cutting face 5 is arranged to
20 °, the angle between outer oblique face 8 and interior cutting face 7 is arranged to 45 °；It is reasonable that above-mentioned angle is set, and gradient is moderate, both protects
Chip removal effect and can is demonstrate,proved and has ensured that cutting resistance is moderate.
In order to strengthen the intensity of cutter tooth, the internal diameter of cylindrical conduit 3 is 3 with the external diameter ratio of the cutter head:5；So, cutter tooth
Rugosity can be guaranteed, be not easily broken and wear.
In order to further improve chip removal efficiency, the cell wall front end of chip area 9 opens up jagged 10；Breach 10 connects two phases
Adjacent cutter tooth, the transition face of breach 10 and one of cutter tooth（The transition face top is blade）For perpendicular, with another
The transition face of cutter tooth is smooth surface；So, the chip that blade is cut directly is discharged by the perpendicular mostly,
Small part chip can enter next chip area behind oblique face by the smooth surface of next breach.
Annular groove is opened up to the grinding tool at narrow place for convenience, handle of a knife 1 includes cone body 11 and cone neck 13, and the cone body 11 passes through
First tapering transition face 12 is connected with cone neck 13, and cone neck 13 is connected by the second tapering transition face 14 with cutter head 2, the first taper
The cone angle for crossing face 12 is 60 °, and the cone angle in the second tapering transition face 14 is 30 °；Wherein, the diameter of body 11, cone neck 13 and cutter head 2 is bored
Successively decrease successively so that cutter head 2 can be stretched into narrow slit.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
Among scope.
