Specific implementation mode
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
The fluted drill Sharpening device of the present invention, can install and use on cylindrical grinder or surface grinding machine.It is used
Sharpening way be Taper section sharpening method, principle as shown in Figure 1, for fluted drill needed for obtaining conical surface flank, then need to ensure
The grinding wheel 19 of sharpening is overlapped with the element of cone 20 of fried dough twist drill bit, while to be completed to semi-cone angle δ (element of cone 20 and circular cone
Angle between axis 21), interaxial angle θ (angle between fluted drill axis 22 and circular cone axis 21), the vertex of a cone is away from A (fluted drills
Axis 22 is at a distance from the intersection point to circular cone top of element of cone 20) and offset distance e (on fluted drill end on projection direction, fluted drill
The distance between axis 22 and circular cone axis 21) etc. forming parameters adjustment.In addition, shaping the flank of fluted drill in order to prevent
It generates " sticking up tail ", and ensures fluted drill chisel edge angle ψ in defined reasonable value range, before fluted drill sharpening clamps, not only
The adjustment of above-mentioned grinding parameter is completed, also needs to rotate fluted drill into an angle beta counterclockwise around own axes.Complete fried dough twist
After the adjustment of grinding parameter, the sharpening posture of fluted drill can determine, next make fluted drill past around theoretical cone axis 21
Physical pendulum turns that the sharpening to fluted drill flank can be completed.
The structure of the fluted drill Sharpening device of the present invention is as shown in Fig. 2, including sharpening supporting mechanism A and drill bit clamping device
B two parts.Specifically, the structure of sharpening supporting mechanism A is as shown in Fig. 3 a- Fig. 3 c, including pedestal 6 and it is rotatably dispose on pedestal
Column 4, column 4 is provided with fixing axle along column 4, fixing axle by across column 4 locating shaft 9 and be sleeved on positioning
Second bolt 10 of 9 one end of axis forms, and locating shaft 9 connects latch segment 8 against the other end of column 4, and latch segment 8 is connected with second
Handle 13, locating shaft 9 are fastened on by the second bolt 10 and latch segment 8 on column 4, and 10 trailer card of the second bolt is on column 4
Groove in prevent latch segment 8 around column 4 rotate, by latch segment 8 adjust drill bit clamping device B it is opposite with lathe grinding wheel 19
Rationally, the second bolt 10 is then fastened in the groove of column 4 then can be to prevent for 19 height of drill bit and grinding wheel when highly, to make sharpening
Only latch segment 8 generates rotation when adjusting height and influences grinding parameter semi-cone angle δ.Locating shaft 9 close to the second bolt 10 one
End cap is equipped with the connector 11 with perforation cavity, and connector 11 has the protrusion to match with dove tail shape, along connector
11 are provided with eccentric adjusting sleeve 1 radially across connector 11, and locating shaft 3 is arranged in eccentric adjusting sleeve 1, and 3 both ends of locating shaft pass through
One bolt 2 is fixed, and closely eccentric adjusting sleeve 1 is provided with plunger 12 in one end cavity of 11 remotely located axis 9 of connector.Eccentric adjusting sleeve
1 is connected with first handle 5.
Example, column 4 can be rotated by nut 7 to be installed on pedestal 6.
The structure of drill bit clamping device B is as shown in Fig. 4 a- Fig. 4 c, including connecting plate 18, be provided on connecting plate 18 with it is convex
The dovetail groove 16 that portion's structure matches is additionally provided with the hold assembly for fried dough twist drill bit to be clamped, clamping part on connecting plate 18
Part includes the upper clamp plate 15 being oppositely arranged and lower clamp plate 17 and adjusts the regulating part of distance between upper clamp plate 15 and lower clamp plate 17.
Specifically, lower clamp plate 17 can be fixed on connecting plate 18, it is drilled with threaded hole on connecting plate 18, is then connected by screw rod
Threaded hole and upper clamp plate 15, screw rod connect third handle 14 and carry out, and push upper clamp plate 15 close by rotating third handle 14
The distance between lower clamp plate 17 completes the clamping to drill bit.Since there are certain to slide relatively in cooperation for dovetail groove and protrusion
Shifting amount (i.e. offset distance e), eccentric adjusting sleeve 1 rotate driving plunger 12 around locating shaft 2 and move, and plunger 12 holds out against the face of dovetail groove, to
Make dovetail groove and protrusion after working good, no longer generate sliding, completes the adjustment to grinding parameter offset distance e.
The course of work of the fluted drill Sharpening device of the present invention is as follows：The fluted drill Sharpening device of the present invention is mounted on outer
On the workbench of circle grinding machine or surface grinding machine, fluted drill is clamped by drill bit clamping device B, by controlling fluted drill relative to upper
The overhang (i.e. the clamping length of fluted drill) of clamping plate 15 carrys out the indirect control grinding parameter vertex of a cone away from A；By fluted drill around itself axis
Line rotates a certain angle, and completes the adjustment that angle beta is reversed to grinding parameter, tightening third handle 14 makes fluted drill be clamped in folder
Between plate 15 and lower clamp plate 17；Rotating first handle 5 drives eccentric adjusting sleeve 1 to rotate, to control plunger 12 to dovetail groove 16
It holds out against or unclamps.The relative engagement height of dovetail groove is adjusted, is completed to fluted drill axis and 9 axis of locating shaft (9 axis of locating shaft
Overlapped with circular cone axis 21) between distance adjustment, that is, complete the adjustment to grinding parameter offset distance e；Drill bit clamping device B
It is connected with connector 11 by dovetail groove 16, connector 11 is sleeved in the fixing axle being made of locating shaft 9 and the second bolt 10,
Locating shaft 9 is fixed on by the second bolt 10 on latch segment 8, and 10 trailer card of the second bolt prevents from locking in the groove on column 4
Tight block 8 is rotated around column 4, and latch segment 8 is locked at by second handle 13 on column 4, and column 4 is mounted on pedestal 6 by nut 7
On, unclamp adjustment of the nut 7 by the completion of Rotary cloumn 4 to grinding parameter semi-cone angle δ；Grinding parameter interaxial angle θ is by drill jig
The intrinsic geometric angle for holding the upper and the lower plywood of mechanism determines；After completing to the adjustment of fluted drill grinding parameter, pass through manually side
Method allows drill bit clamping device B around 9 reciprocal rotation of locating shaft, completes the sharpening to fluted drill side conical surface flank, then
Rotation first handle 5 removes drill bit clamping device, and the overturning of drill bit clamping device is positioned for 180 ° by other side dovetail groove, is revolved
Turn first handle 5 to be clamped it, drill bit clamping device is allowed to continue, around 9 reciprocal rotation of locating shaft, to complete to fluted drill pair
The sharpening of side flank.
