Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
State.
As shown in Fig. 1 ~ Fig. 5, a kind of Double-side rounding drilling tool, it includes cutter hub 1, chamfering blade 6 and drill plate 7,
The termination of described cutter hub 1 is provided with blade platform portion 9, longitudinally disposed blade is further opened with the termination of cutter hub 1 and installs cross-drilled hole
19, the right-hand member of cutter hub 1 is provided with clamping part 28, and the inside of cutter hub 1 offers axial hole 20, and one end of extension rod 3 passes through clamp screw
Nail 2 is positioned and installed on the interior of axial hole 20, and the other end of extension rod 3 is connected with spring 4, and spring 4 is connected with spacer pin 5；Institute
The drill plate 7 stated is installed in blade platform portion 9 by housing screw 8；Offered on the longitudinal direction of described chamfering blade 6
Groove 12, the bottom side of the wall of groove 12 is that the first inclined-plane 13 and the second inclined-plane 14 are seamlessly transitted, and the upper end side wall 11 of groove 12 is
Square side wall, offers front chamfering cutting edge 17 and reverse side chamfering cutting edge 16, chamfering blade 6 on the cutting face of chamfering blade 6
Installed in cross-drilled hole 19 installed in blade, lock and spacing chamfering blade 6 in the insertion groove 12 of spacer pin 5.
Further, as the preferred embodiment of the present invention, described spacer pin 5 includes cylindrical portion 22 and spacer pin
Right side 23, cylindrical portion 22 is vertically mounted on spacer pin right side 23, and the free end of cylindrical portion 22 is provided with arc surface 21；It is described
Spring 4 be compression spring；Described the first inclined-plane 13 and the second inclined-plane 14 is inclined toward same direction, and they are upper with groove 12
The corner dimension a1 of the composition of side wall 11<a2；Lateral arc surface 18, lateral arc surface 18 are offered on described chamfering blade 6
Radius less than drill plate 7 boring radius.
Installation process of the invention and use process are as follows：By each parts of the invention according to the company shown in Fig. 1 ~ 4
The relation of connecing is installed and processed, and can be begun to use after installation of the present invention.First, chamfering blade 6 is inserted into blade peace
Dress cross-drilled hole 19, the fillet surface 11 of chamfering blade 6 is contacted with the arc surface 21 of spacer pin, and the installation direction along chamfering blade 6 applies
Certain power, spring 4 is compressed, and in axial hole 20 of the spacer pin 5 along the indentation cutter hub 1 of cutter axial line 29, spring 4 is compressed,
After arc surface 21 bypasses fillet surface 10, spacer pin 5 is rebounded by spring 4, and the arc surface 21 and cylindrical portion 22 of spacer pin 5 are distinguished
The inclined-plane 13 of upper end side wall 11 and first of groove 12 is contacted, now chamfering blade 6 is limited pin 5 and locks；And then, by drill plate
7 are installed in blade platform portion 9 with housing screw 8, and cutter holding portion 28 is installed on the output main shaft of Digit Control Machine Tool, start electricity
Source, is first drilled with the drill plate 7 of front end, after the completion of drilling, without tool changing, is moved on, using chamfering blade 6
Front chamfering cutting edge 17 carries out the positive surface chamfer in aperture, when positive surface chamfer is completed, increases the amount of feeding, now the institute of chamfering blade 6
Increased by axial force, by the first inclined-plane 13, arc surface 21 enters the second inclined-plane 14, chamfering blade 6 to the arc surface 21 of spacer pin 5
Cross-drilled hole 19 just is installed along blade to move, now the lateral arc surface 18 of chamfering blade 6 is tangent with borehole wall contacts, due to lateral
Boring radius Rbs, i.e. Ra of the radius Ra of arc surface 18 less than drill plate 7<Rb, so chamfering blade 6 can pass through drilling
Hole wall；When chamfering blade 6 passes through borehole wall completely, bounce of the chamfering blade by spring 4 so that chamfering blade 6 is returned again
To initial position, now blade is locked again, and Digit Control Machine Tool is retreated according to normal cutting parameter again, using reverse side chamfering cutting edge
The 16 reverse side chamferings for carrying out aperture；When reverse side chamfering is completed, the amount of feeding is increased again, now axial force suffered by chamfering blade 6
Increase, by the first inclined-plane 13, arc surface 21 is again introduced into the second inclined-plane 14 to the arc surface 21 of spacer pin 5, and chamfering blade 6 is with regard to edge
Blade is installed cross-drilled hole 19 and is moved, and now the lateral arc surface 18 of chamfering blade 6 is tangent with borehole wall contacts, and waits cutter all to move back
When going out borehole wall, chamfering blade 6 is returned to initial position, ready to process next hole or workpiece.
The above is only the preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
Form, is not to be taken as the exclusion to other embodiment, and can be used for various other combinations, modification and environment, and can be at this
In the text contemplated scope, it is modified by the technology or knowledge of above-mentioned teaching or association area.And those skilled in the art are entered
