Brief description of the drawings
Fig. 1 is the structure diagram of the utility model orifice chamfer set knife.
Embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments：
Referring to Fig. 1, the utility model provides a kind of orifice chamfer set knife, including drill bit 1, it is arranged with outside the drill bit 1
One tool apron 2；The tool apron 2 is equipped with a movable span 3, and drill bit 1 is located in movable span 3, exists between drill bit 1 and movable span 3 and lives
Dynamic spacing；2 outer surface of tool apron is equipped with least one tightening screw hole 4 to connect with movable span 3；In the tightening screw hole 4
Screw 5 is bolted with, screw 5 presses on 1 surface of drill bit；2 lower end of tool apron is equipped with tapered portion 6；The tapered portion 6
Surface is equipped with a blade mounting plane 7；The wound of blade mounting plane 7 is fixed with blade 8；It is solid that one is arranged with outside the drill bit 1
Determine ring 9, retainer ring 9 is located at the top of tool apron 2；Pass through some adjustings being circularly and evenly distributed between the retainer ring 9 and tool apron 2
Arm group 10 is connected；The regulating arm group 10 has a secured adjusted arm 1001 fixed with 9 phase of retainer ring and is hinged with tool apron 2
Activity adjustment arm 1002 forms；The activity adjustment arm 1002 is hinged with secured adjusted arm 1001；The secured adjusted arm
1001 are equipped with a limited block 11；11 bottom of limited block is equipped with a cushion 12, cushion 12 and activity adjustment arm
1002 upper ends are in contact；It is connected between the activity adjustment arm 1002 by regulation ring 13, regulation ring 13 and activity adjustment arm
1002 are hinged；13 center of regulation ring is equipped with cushion hole 14；Rubber sleeve 15, rubber sleeve are arranged with outside the drill bit 1
15 in cushion hole 14；There is buffering spacing 16 between the cushion hole 14 and rubber sleeve 15.
Fixed between the blade 8 and blade mounting plane 7 by screw 17.
2 outer surface of tool apron is equipped with least two tightening screw holes 4 being circularly and evenly distributed.
The height of the rubber sleeve 15 is at least twice of 13 thickness of regulation ring.
The application method of the utility model is as follows：
First the drill bit 1 of the utility model is fixed on drilling machine, then the section bar that need to be punched is fixed on workbench, so
Afterwards by rotating handwheel, decline drill bit 1, the vertex on 1 head of drill bit is slowly aligned to the machining center point got on section bar, it is right
After standard, drill bit 1 continues to move down, and starts to cut section bar, finally gets hole.
During drill bit 1 moves down, tool apron 2 moves down therewith, and when drill bit 1 rotates, tool apron 2 keeps same with drill bit 1
Speed rotation, therefore remain concentric between tool apron 2 and drill bit 1, after the completion of the drilling of drill bit 1, drill bit 1 continues to move down, until
Blade 8 is in contact with aperture, and with moving down for tool apron 2, blade 8 can cut aperture, and blade 8 is fixed on blade peace
Fill in plane 7, blade mounting plane 7 on 6 surface of tapered portion, once blade 8 cuts aperture, will be cut again
One inclined-plane, so as to complete chamfering work, the burr in aperture is removed completely.
Remain that Concentric rotation can ensure the uniformity of chamfering by tool apron 2 and drill bit 1, though screw 5 by
The influence of the shaking force produced to the drilling of drill bit 1 loosens, and causes tool apron 2 eccentric there is a situation where rolling, can also pass through tune
Joint arm group 10 makes tool apron 2 remain the concentric situation with drill bit 1 come 2 position of tool apron that automatically adjusts, when tool apron 2 to
When one and being sloped downwardly, the opposite side of tool apron 2 is inclined upwardly, and with tool apron 2, the side is inclined upwardly, with the side phase of tool apron 2
The activity adjustment arm 1002 of connection pushes upwards, and 1002 upper end of activity adjustment arm extrudes cushion 12, at this time cushion
12 form opposite effect power, and activity adjustment arm 1002 is squeezed back original state, so that tool apron 2 resets, continuation is protected with drill bit 1
Hold the uniformity for one heart, ensureing chamfering.
It is connected between activity adjustment arm 1002 by regulation ring 13, the presence of regulation ring 13 can play balancing activity tune
The effect of joint arm 1002, accelerates the reset case of activity adjustment arm 1002, and the presence of buffering spacing 16 can make regulation ring 13 exist
With enough cushion spaces when 1002 state of activity adjustment arm changes, the activity of activity adjustment arm 1002 will not be produced
Suppress, when the active actions of activity adjustment arm 1002 are excessive, the cushion hole 14 at 13 center of regulation ring will be sent out with rubber sleeve 15
Raw contact, once 14 wall of cushion hole extrudes rubber sleeve 15, rubber sleeve 15 can then carry out regulation ring 13 by elastic force
Reset and adjust, further speed up the reset speed of activity adjustment arm 1002, ensure that tool apron 2 is concentric with drill bit 1 all the time.
Fixed between blade 8 and blade mounting plane 7 by screw 17, thus can quick tool setting piece 8 carry out fast assembling-disassembling,
When blade 8 needs replacing, can complete to replace within the shortest time.
2 outer surface of tool apron is equipped with least two tightening screw holes 4 being circularly and evenly distributed, and ensures the uniform of 2 stress of tool apron
Property, be not in that the situation for causing bias is fixed in side, at utmost ensure that concentricity.
The height of rubber sleeve 15 is at least twice of 13 thickness of regulation ring, ensures that regulation ring 13 is lived in activity adjustment arm 1002
The amplitude of moving can be in contact when excessive with rubber sleeve 15, the effect of 13 auxiliary reset of regulation ring is protected.
