Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：Institute as shown in Figure 1 to Figure 4
Show, a kind of quick drill and functions of reaming, chamfering knife, including cutter hub 1, the cutter hub 1, which is provided with, is disposed with bore portion 11, reamer
12 and chamfered section 13, the tactical diameter of the bore portion 11, reamer 12 and chamfered section 13 increase successively, the bore portion 11 is set
Center cutter groove 111 and periphery cutter groove 112 are equipped with, center cutter 2 is installed in the center cutter groove 111, in the periphery cutter groove 112
Periphery knife 5 is installed, the reamer 12 is provided with reaming cutter groove 121, cornish bit 3, institute are provided with the reaming cutter groove 121
State chamfered section 13 and be provided with chamfering cutter groove 131, rose reamer 4 is installed in the chamfering cutter groove 131.
The cutting edge of the center cutter 2 is protruded outside the bottom margin of the bore portion 11.
The point of a knife of the periphery knife 5 is protruded outside the ora terminalis of the bore portion 11.
The reaming cutter groove 121 is provided with the first block face 122, and first block face 122, which is acted on cornish bit 3, prevents it
Shift in cutting.
3 point of a knife of cornish bit is protruded outside the ora terminalis of the reamer 12.
The chamfering cutter groove 131 is provided with the second block face 132, and second block face 132, which is acted on rose reamer 4, prevents it
Shift in cutting.
The cutting edge of the rose reamer 4 is protruded outside the edge of the chamfered section 13.
As shown in Figure 4, when the present apparatus works, bore portion 11 and workpiece 10 contacted before this, started to drill；When drilling carries out
After to a certain extent, reamer 12 contacts workpiece 10, so as to start the hole to originally processing, carries out reaming work.Finally, fall
Corner 13 contacts workpiece, to the hole being extended, carries out chamfered, prevents from cutting hand.In this way, the cutter of the present apparatus, it is only necessary to one
