Referring to Fig. 1, Fig. 1 is the structural representation of T-shaped milling cutter in the utility model embodiment.The utility model embodiment
A kind of T-shaped milling cutter 100 provided, including handle of a knife 10 and processing department 30, one end of handle of a knife 10 are connected with one end of processing department 30.
Specifically, handle of a knife 10 is cylinder, T-shaped milling cutter 100 has rotation axis A, rotation axis A and handle of a knife 10 axis
Overlap.When being processed using T-shaped milling cutter 100, the T-shaped milling cutter 100 is rotated around rotation axis A.
Above-mentioned processing department 30 has a shaft core 31, and land 32 and chip pocket 33, the He of land 32 are provided with the shaft core 31
Chip pocket 33 is in the shape of a spiral.Land 32 and chip pocket 33 are set around the lateral surface of shaft core 34, and land 32 and chip pocket
33 are arranged at intervals.Described one end of shaft core 31 is connected with one end of the handle of a knife 10.The shaft core 31 is cylinder, and its diameter is less than
The diameter of the handle of a knife 10.
In the utility model embodiment, the number of the land 32 and chip pocket 33 is four, and the land
32 and chip pocket 33 relative to the rotation axis A Central Symmetries.
On the axial direction of the shaft core 31, the land 32 is a machined surface close to one end end face of the handle of a knife 10
321.The junction of the handle of a knife 10 and the land 32 sets fluted 11, and the groove 11 connects with the machined surface 321.
Due to the T-shaped milling cutter 100 machined surface 321 for land 32 close to one end end face of the handle of a knife 10, therefore use the T-shaped milling
When knife 100 is processed, its milling mode is milling from lower to upper.The junction of the handle of a knife 10 and the land 32 is provided with
Groove 11, the groove 11 connect with the machined surface 321, can not only make it that the area of machined surface 321 is bigger, can also keep away
Exempt from after being processed using the T-shaped milling cutter 100 to workpiece, the undressed part arrived is left on workpiece, so as to the shape on workpiece
Into step.
One end of the handle of a knife 10 is provided with guiding groove 12, and the guiding groove 12 is interconnected with the chip pocket 33, and
And the guiding groove 12 and the chip pocket 33 are smooth excessively.The guiding groove 12 corresponds with the chip pocket 33, described
Groove 11 corresponds with the land 32.The groove 11 and guiding groove 12 are arranged at intervals, and the groove 11 with it is described
Guiding groove 12 is interconnected.The benefit of such a structure is：When being processed using the T-shaped milling cutter to workpiece, the machined surface
Chip of 321 part in groove 11 from workpiece under milling can enter guiding groove 12 by groove 11, then by guiding groove
12 enter in chip pocket 33, and finally one end away from the machined surface 321 is discharged from chip pocket 33.Chip can so be prevented
Remain on machined surface 3a21, so as to influence the machining accuracy of the T-shaped milling cutter, and can prevent cut occur on the surface of workpiece.
Referring to Fig. 2, and combine Fig. 1, in the shaft core 31 in the radial direction, above-mentioned land 32 is away from the shaft core 31
One end be provided with cutting edge 322.One end of the cutting edge 322 connects with the machined surface 321.The cutting edge 322 wraps
Include the first machined surface 3221, the second machined surface 3222 and the 3rd machined surface 3223.The cutting edge of cutting edge 322 is by the first machined surface
3221 and second machined surface 3222 be crossed to form, and the second machined surface 3222 also connects with the 3rd machined surface 3223.Described
The angle of one machined surface 3221 and the second machined surface 3222 is acute angle, the machined surface 3223 of the first machined surface 3221 and the 3rd
Angle is also acute angle, and the angle of the machined surface 3222 of first machined surface 3221 and second is more than first machined surface
3221 and the 3rd machined surface 3223 angle.The benefit of such a structure is：The machined surface of first machined surface 3221 and second
3222 angle is larger, may be such that cutting edge 322 while with sharp cutting edge, its cutting edge rear has larger thickness
Degree so that cutting edge 322 has high intensity, can effectively prevent that cutting edge 322 occurs when being processed using cutting edge 322
Excessive wear or the situation of fracture, so as to extend the service life of cutting edge 322.Second machined surface 3222 and the 3rd machined surface
3223 angular range is 9 to 15 degree.Preferably, the angle of the second machined surface 3222 and the 3rd machined surface 3223 is 12 degree.
The beneficial effects of the utility model are：Compared with prior art, the utility model provides a kind of T-shaped milling cutter 100,
Including：Handle of a knife 10 and processing department 30, wherein, the processing department 30 has a shaft core 31, described one end of shaft core 31 and the handle of a knife
10 connect, and are provided with land 32 and chip pocket 33 in the shaft core 31, the land 32 and chip pocket 33 are set around the axle
The lateral surface of core 31, and the land 32 has a machined surface 321, the handle of a knife 10 and institute close to one end of the handle of a knife 10
The junction for stating land 32 sets fluted 11, and the groove 11 connects with the machined surface 321.Not only may be used based on above structure
To cause the area of machined surface 321 bigger, can also avoid after being processed using the T-shaped milling cutter 100 to workpiece, on workpiece
The undressed part arrived is left, so as to form step on workpiece.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
