Description

A kind of graver knife sharpener

Technical field

It the utility model is related to a kind of graver knife sharpener.

Background technology

Artistic carving be unable to do without all kinds of engraving cutters, and the blade of graver grinds effect and directly affects engraving effect and effect Rate；Conventional graver grinds generally use human hand and grips and whet a knife on abrasive machine, and sharpening angle is because hand-held without solid Fixed, the moment can change, so as to cause blade not straight enough, easily grind away, it is necessary to grind again repeatedly, cause tool bit abrasion More, utilization rate is low, needs further improvement.

Utility model content

In view of the above-mentioned state of the art, the technical problem to be solved by the utility model is to provide one kind to keep Sharpening angle is fixed, and can adjust sharpening angle as needed, ensure that blade is straight, grinds efficient, and tool bit abrasion is small, greatly The big graver knife sharpener for improving cutter head utilization rate.

Technical solution is used by the utility model solves above-mentioned technical problem：A kind of graver knife sharpener, including bottom Plate, knifeboard, U-shaped frame, sole piece, jacking block, wing nut, bolt, roller, screw, nut, plain cushion and spring washer, it is characterised in that Knifeboard is fixed with the upper plane of the bottom plate；Supporting plate is formed on the U-shaped frame, the both ends of the supporting plate are outwards vertical Two symmetrical flaps are formed, a symmetrically distribution is offered in the outer lateral side of described two flaps First through hole, offer two the second symmetrical through holes on the medial plane of the supporting plate；Put down the side of the sole piece Offer two symmetrical third through-holes on face, the size of described two third through-holes and position and two the second through holes Size and position are engaged；The side planar central of the sole piece is further opened with half slot；Opened on one side plane of the jacking block Equipped with two symmetrical fourth holes, the size of the size of described two fourth holes and position and two the second through holes and Position is engaged.

Preferably, the screw sequentially passes through spring washer, first through hole, roller and plain cushion and is screwed into nut from inside to outside In, so as to the roller is connected to outside the side of U-shaped frame, the roller can be using screw as axis rotation.

Preferably, the bolt sequentially passes through the second through hole on U-shaped frame, the third through-hole on sole piece and top from the bottom up Fourth hole on block is simultaneously screwed into wing nut.

Compared with prior art, the utility model has the advantage of：Artistic carving be unable to do without all kinds of engraving cutters, graver Blade grind effect and directly affects engraving effect and efficiency；Conventional graver grinds generally use human hand and grips and in sand Whet a knife on turbine, sharpening angle is not fixed because hand-held, and the moment can change, so as to cause blade not straight enough, is held Easily grind away, it is necessary to grind again repeatedly, cause tool bit abrasion more, utilization rate is low；The utility model can keep sharpening angle to consolidate It is fixed, and sharpening angle can be adjusted as needed, it ensure that blade is straight, grind efficient, tool bit abrasion is small, substantially increases knife Head utilization rate.

Embodiment

As shown in figures 1-4, a kind of graver knife sharpener, including bottom plate 1, knifeboard 2, U-shaped frame 3, sole piece 4, jacking block 5, butterfly Shape nut 6, bolt 7, roller 8, screw 9, nut 10, plain cushion 11 and spring washer 12；Knifeboard 2 is fixed with the upper plane of bottom plate 1, Forming supporting plate 34 on U-shaped frame 3, the both ends of supporting plate 34 outwards vertically form two symmetrical flaps 31, and two A first through hole being symmetrically distributed 32 is offered in the outer lateral side of a flaps 31, is opened on the medial plane of supporting plate 34 Equipped with two the second symmetrical through holes 33；Two symmetrical third through-holes 41 are offered on one side plane of sole piece 4, The sizes of two third through-holes 41 and position are engaged with the size of two the second through holes 33 and position；One side plane of sole piece 4 Center is further opened with half slot 42；Offer two symmetrical fourth holes 51 on one side plane of jacking block 5, two the 4th The size of through hole 51 and position are engaged with the size of two the second through holes 33 and position；Worn successively from inside to outside using screw 9 A spring washer 12,32, rollers 8 of one of first through hole and a plain cushion 11 are crossed, is finally screwed into a nut 10, Similarly, another screw 9 also according to said method passes through a spring washer 12,32, rollers 8 of another first through hole and a plain cushion 11 and it is screwed into each and every one another nut 10, so as to two rollers 8 are connected to outside the both sides of U-shaped frame 3,8 energy of roller It is axis rotation with screw 9；Sequentially pass through accordingly one of them second through hole on U-shaped frame 3 from the bottom up using bolt 7 33rd, accordingly one of fourth hole 51 on the accordingly one of third through-hole 41 and jacking block 5 on sole piece 4 and it is screwed into Into a wing nut 6, similarly, another bolt 7 is also according to said method through another second through hole 33,41 and of third through-hole Fourth hole 51 is screwed into another wing nut 6, so that U-shaped frame 3, sole piece 4 and jacking block 5 be linked together；In use, The penholder of graver 13 is snapped onto in the half slot 42 on sole piece 4 and according to sharpening angle needs to be adjusted to suitable position Put, then screw two wing nuts 6, so that jacking block 5 compressed downwards to the penholder of graver 13, so that graver 13 be fixed Between sole piece 4 and jacking block 5；The penholder for finally grasping graver 13 moves back and forth so that the cutter head of graver 13 is being ground Slided on knife plate 2 and realize sharpening, the angle of sharpening can lean out the length come by adjusting handle of a knife and be adjusted to realize；Grind flat cutter During, it is necessary to make knife edge angular parallel with knifeboard 2, and check that whether suitable blade or so is straight；Oblique knife is ground according to oneself Requirement adjustment handle of a knife lean out the length come, then left rotation and right rotation handle of a knife adjustment left and right gradient, then clamps, firmly uniform, comes Drawing is pushed back, antirust is dried in time using finishing.

Artistic carving be unable to do without all kinds of engraving cutters, and the blade of graver grinds effect and directly affects engraving effect and effect Rate；Conventional graver grinds generally use human hand and grips and whet a knife on abrasive machine, and sharpening angle is because hand-held without solid Fixed, the moment can change, so as to cause blade not straight enough, easily grind away, it is necessary to grind again repeatedly, cause tool bit abrasion More, utilization rate is low；The utility model can keep sharpening angle to fix, and can adjust sharpening angle as needed, ensure that knife Sword is straight, grinds efficient, and tool bit abrasion is small, substantially increases cutter head utilization rate.

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations； Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to It can so modify to the technical solution described in foregoing embodiments, or which part technical characteristic is replaced on an equal basis Change；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the utility model technical solution Spirit and scope.
