Detailed description of the invention
Below by combining the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
See in figure, this utility model provide Novel composite drill include matrix and be arranged on base end for punching
Cutter head, matrix includes discoid leaning portion 2, and the two ends leaning portion 2 have convexed to form a junction 1 and a knife bar portion, top
The diameter of relying part 2, more than the diameter of connecting portion 1, leans the diameter diameter more than knife bar portion in portion 2, and this composite drill bit is by connecting
Portion 1 is arranged on drilling machine, and connecting portion 1 is provided with along the axially arranged locating surface 11 of matrix, it is simple to Fast Installation composite drill bit.Cutter
There is in bar portion chamfered section 4 and bore portion 7, bore portion 7 for workpiece is holed, chamfered section 4 at hole drill to certain depth
Time the surface in hole is carried out chamfering.Bore portion 7 protrudes the one end being formed at chamfered section 4, and bore portion 7 and chamfered section 4 are coaxially disposed
And the diameter of chamfered section 4 is greater than the diameter of bore portion 7, so make to be formed between chamfered section 4 and bore portion 7 ladder
Face.The front end of bore portion 7 has the first installing hole and the second installing hole, is provided with the first drill plate 91 in the first installing hole,
Second drill plate 92 is installed in second installing hole, the first drill plate 91 and the second drill plate 92 all in quadrilateral shape and
Detachable, the direction, cutting face along the first drill plate 91 is provided with the first cutting slot 9, along the cutting of the second drill plate 92
Direction, face is provided with the second cutting slot 9a, and the first cutting slot 9 and the second cutting slot 9a extends to intersecting of bore portion 7 and chamfered section 4
Place.Chamfered section 4 is provided with the chip area that cross section is V-shaped, the respectively first chip area 8 and the second chip area 8a, the first chip removal
Groove 8 and the first cutting slot 9 UNICOM, the second chip area 8a and the second cutting slot 9a UNICOM, owing to the diameter of chamfered section 4 is more than boring
The diameter in portion 7, the transversal breach size of chip area is greater than the transversal breach size of cutting slot.Between chamfered section 4 and bore portion 7
Be provided with tapering transition face 5, tapering transition face 5 is provided with rose reamer, specifically, the first chip area 8 is provided with first fall
Angle cutter 6, the cutting face of the first rose reamer 6 protrudes the installed surface at its place, and the cutting portion of the i.e. first rose reamer 6 protrudes chamfered section 4
And the tapering transition face 5 between bore portion 7, same, in the second chip area 8a, it is provided with the second rose reamer 6a, the second rose reamer
The tapering transition face 5 between chamfered section 4 and bore portion 7 is also protruded in the cutting face of 6a.
This Novel composite drill is in actual application, and drilling machine drives composite drill bit to rotate, and is positioned at the cutter head of bore portion 7
Perforate hole is beaten deep on workpiece, when the degree of depth in hole make chamfered section 4 can with absorption surface position time, in chamfered section 4
First rose reamer 6 and the second rose reamer 6a carries out chamfering to the surface in hole, disposably can complete drilling and chamfering work, add work efficiency
Rate is higher.In the whole course of processing, the chip that boring produces is first along the first cutting slot 9 and the second cutting slot 9a tap
Outward, discharging drill bit via the first chip area 8 and the second chip area 8a afterwards, whole chip removal process is smooth and easy, is difficult to occur that chip blocks up
Plug, causes cutting fluid cannot contact very well so that cutter head is overheated with cutter head.
As preferably, leaning the transition face 3 being provided with arc between portion 2 and knife bar portion, the setting of arc transiting surface 3 makes
First chip area 8 and the second chip area 8a is more prone to machine-shaping.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
