Accompanying drawing explanation
Fig. 1 is the schematic perspective view of the gang tool of the utility model one embodiment;
Fig. 2 is the end view of gang tool shown in Fig. 1.
Detailed description of the invention
As shown in Figure 1, it is the schematic perspective view of the gang tool 10 of the utility model one embodiment.Gang tool 10 comprises: handle of a knife 100, first cutting portion 200 connected in turn and the second cutting portion 300, and handle of a knife 100, first cutting portion 200 and the second cutting portion 300 have same rotary middle spindle 011.In the present embodiment, handle of a knife 100 is in cylindrical shape.
First cutting portion 200 is provided with the first cutting knife 210, second cutting knife 220, the 3rd cutting knife 230 and the 4th cutting knife (not showing in Fig. 1) first cutting knife 210, second cutting knife 220, the 3rd cutting knife 230 and the 4th cutting knife evenly to arrange around rotary middle spindle 011.Be provided with the first chip area 240 between two adjacent cutting knifes, be provided with the first chip area 240 for the second cutting knife 220 with between the 3rd cutting knife 230, second cutting knife 220 and the 3rd cutting knife 230.
In order to when gang tool 10 High Rotation Speed, ensure that cutting the chip produced can discharge via the first chip area 240 in time swimmingly, first chip area 240 is obliquely installed relative to rotary middle spindle 011, that is, the bearing of trend of the first chip area 240 is not parallel with the length direction of rotary middle spindle 011.Like this, be convenient to when gang tool 10 High Rotation Speed, ensure that cutting the chip produced can discharge via the first chip area 240 in time swimmingly.In order to the chip improving generation is further discharged swimmingly via the first chip area 240 in time, in the present embodiment, the first chip area 240 has certain helicity.Second cutting portion 300 offers spiral helicine second chip area 310.Cut for the ease of the second cutting portion 300 chip produced can discharge via the second chip area 310, first chip area 240 successively, point to the first chip area 240 near one end of the second chip area 310 of the first cutting portion 200.
In order to adapt to the cutting of groove to the size that varies in size or hole, each cutting knife comprises integrated first blade and the second blade, first blade is arranged near the first cutting portion, second blade is arranged near the second cutting portion, and the rotation round diameter of the first blade is greater than the rotation round diameter of the second blade.For the second cutting knife 220, second cutting knife 220 comprises integrated first blade 221 and the second blade 222, wherein, first blade 221 is arranged near the first cutting portion 200, second blade 222 is arranged near the second cutting portion 300, and the rotation round diameter of the first blade 221 is greater than the rotation round diameter of the second blade 222.
In order to the junction realizing the shaping groove of the shaping groove of the first blade cut or hole and the second blade cut or hole forms chamfering, in the present embodiment, the intersection of the first blade and the second blade forms arc angling.Arc angling is formed for the intersection of the second cutting knife 220, first blade 221 and the second blade 222.
In order to adapt to the cutting of groove to smaller szie or hole, in the present embodiment, the rotation round diameter of the second cutting portion 300 is less than the rotation round diameter of the second blade 222.
See also Fig. 1 and Fig. 2, in order to adapt to the cutting of groove to smaller szie or hole, in the present embodiment, the rotation round diameter of the first blade 221 is greater than the circle diameter of handle of a knife 100.
In order to gang tool 10 can realize the cutting process of end face milling, the second cutting portion 300 is removably connected with the first cutting portion 200.Like this, the first cutting portion 200 just can complete the cutwork of end face milling.
In order to strengthen the abrasivity of the first cutting portion 200, the outer surface of the first cutting portion 200 has titanium carbonitride layer, or the outer surface of the first cutting portion 200 has aluminium nitride titanium layer.
In order to strengthen the abrasivity of the second cutting portion 300, the outer surface of the second cutting portion 300 has aluminium nitride titanium layer, or the outer surface of the second cutting portion 300 has titanium carbonitride layer.
For the ease of changing the second cutting portion 300, second cutting portion 300 and the first cutting portion 200 removably connects.Like this, after the second cutting portion 300 weares and teares, only need change the second cutting portion 300, provide cost savings.
Combinations thereof cutter 10, by the first cutting portion 200 and the second cutting portion 300, realizes the cutting in groove to the size that varies in size or hole, to merge multiple tracks cutting process, reduce cutter number and to change time of cutter, reduces the impact on cutting precision.First chip area 240 is obliquely installed relative to rotary middle spindle 011, ensures that cutting the chip produced can discharge via the first chip area 240 in time swimmingly.
Each technical characteristic of the above embodiment can combine arbitrarily, for making description succinct, the all possible combination of each technical characteristic in above-described embodiment is not all described, but, as long as the combination of these technical characteristics does not exist contradiction, be all considered to be the scope that this description is recorded.
