Summary of the invention

The invention mainly solves the technical problem of providing a kind of alloy bit grinding device and techniques.

The present invention, which solves technical solution used by its technical problem, is: a kind of alloy bit grinding device, including bores Head, drill bit include alloy head and shank, wherein further include clamping device, rotating mechanism, workpiece polishing mechanism, driving mechanism with And pushing mechanism, clamping device include collet, collet is used to clamp the shank of drill bit, and driving mechanism and clamping device link, by The rotation of driving mechanism realization shank；Pushing mechanism includes push rod, and alloy head portion is located on the motion profile of push rod, and push rod will bore Head, which is pushed into collet, to be fixedly clamped, and workpiece polishing mechanism includes grinding wheel, and workpiece polishing mechanism is located at the side of clamping device, alloy head position In on the motion profile of grinding wheel；Rotating mechanism is located at the lower section of clamping device and rotating mechanism driving clamping device rotation.

Adopt the structure setting, as need to polish on alloy head end cutting edge when, need for the shank of drill bit to be put into To clamping device, by grips, the setting of push rod guarantees that drill bit is put into place, is then once polished by grinding wheel. Multiple face polishings if necessary, are rotated by driving mechanism rotary drill bit or rotating mechanism, so that grinding wheel carries out that shape is polished for a plurality of times At multiple end cutting edges.Such device make alloy bit polishing it is more convenient, by Mechanical Driven, unified standard, polishing is more Add precisely, realizes pile line operation, improve the efficiency integrally polished.

Wherein, driving mechanism includes drive rod and driving motor；Collet is radially clamped with drive rod；Motor and driving It is belt wheel transmission or gear drive between bar, for driving drive rod to rotate.

Driving motor drives so that overall structure transmission is more stable, while collet and the radial of drive rod are clamped, and prevent During the grinding process, shank rotates, and influences the efficiency of polishing.

It wherein, further include clamp system, clamp system includes power source I and pull rod, and pull rod and power source I link, drive Lever is hollow structure, the pull rod other end penetrate in drive rod be radially clamped with drive rod, axially slidable setting；Collet packet Interconnecting piece and claw are included, one end of interconnecting piece is circumferentially arranged in claw at least two；Interconnecting piece and pull rod link；Claw Positioned at the aperture position of drive rod, the outer surface of claw is equipped with inclined-plane I, and drive rod is equipped with inclined-plane close to the aperture position of claw II, inclined-plane I is adapted to inclined-plane II, and the power of pull rod pull direction is converted to the power in claw occlusion direction.

Setting is adopted the structure, by pulling pull rod, inclined-plane I is bonded with inclined-plane II, so that shank is realized in claw occlusion Clamping effect, and drive rod and pull rod are radially clamped, and guarantee drive rod in the course of rotation, pull rod also with rotation, Guarantee whole stability.

It wherein, further include cutting agency, cutting agency includes blanking bar and power source II, II one end of power source and blanking The bar linkage other end can be penetrated to, in the setting that slides axially, when needing blanking, blanking bar is pushed between each claw and with drive rod Drill bit carries out blanking.

The head of drill bit has been clamped, then has carried out blanking if drill bit is under using clamp position by the setting of cutting agency Processing, or blanking processing is carried out after the completion of polishing.Blanking herein is located at the center of drive rod, and sets with drive rod for concentric shafts It sets, drive rod and blanking bar are separated structure, therefore blanking bar does not interfere with the actual use of drive rod.

Wherein, workpiece polishing mechanism is equipped with positioning device, and positioning device includes pilot pin and infrared locator, infrared positioning The focus of device is located on the motion profile of pilot pin and positioning device and workpiece polishing mechanism link.

Using the setting of positioning device, guarantees that the initial position of drill bit is accurate, guarantee whole grinding effect.Such as initial bit It is equipped with offset, then controls driving mechanism rotary drill bit；If initial position is directly the shank of drill bit, then control under cutting agency Material, prevents accidentally to polish.

It wherein, further include feeding mechanism, feeding mechanism is equipped with inclined ramp, and inclined ramp is equipped with limiting slot, drill bit In array distribution in inclined ramp, the drill bit of least significant end is located on the motion profile of push rod.

Feeding mechanism uses such setting, guarantees that several drill bits in inclined ramp, guarantee neatly have in array distribution The arrangement of sequence, the baffle of two sides can also carry out length adjustment by bolt herein.

Wherein, feeding mechanism is equipped with limit plate and limit driving mechanism, and limit driving mechanism driving limit plate is mobile, Limit plate separates the drill bit of least significant end with remaining drill bit.

Limit plate is straight cutting between two drill bits of least significant end, is moved up passing through, directly by the drill bit of least significant end and other Drill bit is kept completely separate, and guarantee does not interfere with subsequent buffing operations in operation.

It wherein, further include fine grinding fluid mechanism, fine grinding fluid mechanism includes the pump housing, spray head and fine grinding fluid, and the pump housing is by fine grinding fluid Pass through the top of spray head spray to grinding wheel and the polishing of alloy head.

Using the setting of fine grinding fluid, workpiece surface finish is being significantly improved, abrasion of grinding wheel is reduced, is improving grinding efficiency, Extend service life, reduces environmental pollution.

A kind of alloy bit technique for grinding the steps include: including a kind of above-mentioned alloy bit grinding device

A: feeding: feeding mechanism feeding；

B: push clamping: pushing mechanism pushes the drill bit of least significant end, and drill handle part is fixedly clamped by collet；

C: location determination: infrared locator judges the position on alloy head, driving mechanism or cutting agency work with pilot pin；

D: primary polishing: workpiece polishing mechanism driving grinding wheel is once polished；

E:N polishing: driving mechanism rotary drill bit, workpiece polishing mechanism drive grinding wheel to carry out n times polishing；

F: blanking: cutting agency drives the blanking of blanking bar.

Using such processing technology, so that alloy bit polishing is more convenient, passes through Mechanical Driven, unified standard, polishing It is more accurate, it realizes pile line operation, improves the efficiency integrally polished.Realize integrated automation operation, operator only needs to control The operation of feeding processed is greatly saved manually, improves positive production efficiency.

Wherein, G: projection detection: by projection scanning, judge whether the end cutting edge polished on drill bit is qualified.

It is detected by projection, it is only necessary to magnified sweep, to go to judge whether the end cutting edge of polishing is qualified, ensure that detection Accuracy.Compared with the existing technology by manually measuring, since the alloy head of drill bit is smaller, and including several oblique Face, measurement accuracy is not high, by projection measurement, so that data are more accurate.
