Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The fluted drill Sharpening device of the utility model can be installed and used on cylindrical grinder or surface grinding machine.Its The sharpening way of use is Taper section sharpening method, and principle then needs as shown in Figure 1, to obtain the conical surface flank of required fluted drill Guarantee sharpening grinding wheel 19 be overlapped with the element of cone 20 of fried dough twist drill bit, while to complete to semi-cone angle δ (element of cone 20 and Angle between circular cone axis 21), interaxial angle θ (angle between fluted drill axis 22 and circular cone axis 21), the vertex of a cone away from A (fiber crops Flower auger spindle line 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, fiber crops Flower the distance between auger spindle line 22 and circular cone axis 21) etc. forming parameters adjustment.In addition, after shaping fluted drill in order to prevent Knife face generates " sticking up tail ", and ensures fluted drill chisel edge angle ψ in defined reasonable value range, before fluted drill sharpening clamps, The adjustment that not only complete above-mentioned grinding parameter also needs to rotate fluted drill into an angle beta counterclockwise around own axes.It completes After the adjustment of fried dough twist grinding parameter, the sharpening posture of fluted drill be can determine, next make fluted drill around theoretical cone axis 21 reciprocal rotations can complete the sharpening to fluted drill flank.
The structure of the fluted drill Sharpening device of the utility model is as shown in Fig. 2, include sharpening supporting mechanism A and drill bit clamping Mechanism 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 in bottom Column 4 on seat is provided with fixing axle radially across column 4 along column 4, and fixing axle is by passing through the locating shaft 9 of column 4 and covering Second bolt 10 of 9 one end of locating shaft 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 column 4 by the second bolt 10 and latch segment 8, and 10 trailer card of the second bolt is in column It prevents latch segment 8 from rotating in groove on 4 around column 4, drill bit clamping device B and lathe grinding wheel 19 is adjusted by latch segment 8 Relative altitude, so that rationally, the second bolt 10, which is then fastened in the groove of column 4, then may be used for drill bit and 19 height of grinding wheel when making to sharpen Grinding parameter semi-cone angle δ is influenced to prevent latch segment 8 from generating rotation when adjusting height.Locating shaft 9 is close to the second bolt 10 One end be arranged with the connector 11 with perforation cavity, connector 11 has the protrusion that matches with dove tail shape, along even Junctor 11 is provided with eccentric sleeve 1 radially across connector 11, and locating shaft 3 is arranged in eccentric sleeve 1, and 3 both ends of locating shaft are logical It is fixed to cross the first bolt 2, closely eccentric sleeve 1 is provided with plunger 12 in one end cavity of the remotely located axis 9 of connector 11.It is eccentric 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 clamping fried dough twist drill bit, clamping part on connecting plate 18 Part includes the upper clamp plate 15 being oppositely arranged and lower clamp plate 17 and the regulating part for adjusting 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 rotation 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 sleeve 1 rotate the driving movement of plunger 12 around locating shaft 2, and plunger 12 holds out against the face of dovetail groove, thus 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 utility model is as follows: by the fluted drill Sharpening device of the utility model It is mounted on the workbench of cylindrical grinder or surface grinding machine, fluted drill is clamped by drill bit clamping device B, by controlling fluted drill The grinding parameter vertex of a cone is indirectly controlled away from A relative to the overhang (i.e. the clamping length of fluted drill) of upper clamp plate 15;By fluted drill It rotates a certain angle around own axes, completes the adjustment for reversing angle beta to grinding parameter, tightening third handle 14 makes fried dough twist drill point Tightly between upper clamp plate 15 and lower clamp plate 17;Rotating first handle 5 drives eccentric sleeve 1 to rotate, to control plunger 12 to swallow Stern notch 16 holds out against or unclamps.The relative engagement height of dovetail groove is adjusted, it is (fixed to fluted drill axis and 9 axis of locating shaft to complete Position 9 axis of axis is overlapped with circular cone axis 21) between distance adjustment, i.e. adjustment of the completion to grinding parameter offset distance e;Drill bit Clamping device B is connected by dovetail groove 16 with connector 11, and 11 sets of connector is being made of locating shaft 9 and the second bolt 10 In fixing axle, locating shaft 9 is fixed on latch segment 8 by the second bolt 10, groove of 10 trailer card of the second bolt on column 4 Inside prevent latch segment 8 from rotating around column 4, latch segment 8 is locked on column 4 by second handle 13, and column 4 is pacified by nut 7 On pedestal 6, adjustment of the nut 7 by the completion of Rotary cloumn 4 to grinding parameter semi-cone angle δ is unclamped;Grinding parameter interaxial angle θ It is determined by the intrinsic geometric angle of the upper and lower plywoods of drill bit clamping device;After completing to the adjustment of fluted drill grinding parameter, pass through Manually method allows drill bit clamping device B around the reciprocal rotation of locating shaft 9, completes the sword to fluted drill side conical surface flank Mill, then rotates first handle 5 and removes drill bit clamping device, and the overturning of drill bit clamping device is carried out for 180 ° by other side dovetail groove Positioning, rotation first handle 5 are clamped it, and drill bit clamping device is allowed to continue to complete around the reciprocal rotation of locating shaft 9 to fiber crops Flower bores the sharpening of opposite side flank.
