In order to achieve the above purpose, the utility model adopts the technical scheme that:

the utility model provides a tool sharpening tool, includes base, support frame, slider and cutter supporting shoe, and the support frame is including setting up on the base and can horizontal migration's flat board and fixing the riser on the flat board, and one side of riser is along the vertical spout that is equipped with, and the slider is slided and is established the cooperation in the spout, and the cutter supporting shoe sets up in the upper end of slider, is equipped with the through-hole with cutter matched with on the cutter supporting shoe.

The relevant content in the above technical solution is explained as follows:

1. in the scheme, the top of the cutter supporting block is provided with a notch groove along the extending direction, and the notch groove extends downwards and is communicated with the through hole of the cutter supporting block.

2. In the scheme, the upper end of the sliding block is provided with a slotted hole with a trapezoidal cross section, and the bottom of the cutter supporting block protrudes downwards to form a boss matched with the slotted hole.

3. In the above scheme, a plurality of through screw holes are arranged on the sliding block at intervals along the extending direction of the sliding block, and a fastening bolt is screwed into each screw hole respectively.

4. In the above scheme, the riser is located dull and stereotyped middle part, it is dull and stereotyped in the both sides of riser are equipped with a waist type hole respectively, waist type hole downwardly extending to the base, the downthehole screw in respectively of waist type can carry out the fastening bolt fixed to the flat board.

The utility model discloses the theory of operation is: the utility model discloses an adjust dull and stereotyped horizontal position and the vertical position of slider to adjust the position of cutter supporting shoe, and then realize the cutter cooperation in the through-hole of cutter supporting shoe.

Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: because the utility model discloses well cutter cooperation can increase the cutter and with the area of contact of cutter supporting shoe in the through-hole of cutter supporting shoe, cutter stability is good, reduces or avoids the cutter to perhaps rock at the removal of the in-process of polishing, promotes the precision of polishing.

Drawings

Fig. 1 is a schematic structural diagram of a polishing jig.

In the above drawings: 1. a base; 21. a flat plate; 211. a kidney-shaped hole; 22. a vertical plate; 221. a chute; 3. a slider; 31. a screw hole; 4. a cutter supporting block; 41. a through hole; 42. a notch groove; 43. a boss; 5. and (4) a cutter.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example (b):

a knife sharpening jig is shown in the attached drawing 1 and comprises a base 1, a supporting frame, a sliding block 3 and a cutter supporting block 4, wherein the supporting frame comprises a flat plate 21 which is arranged on the base 1 and can move horizontally and a vertical plate 22 which is fixed on the flat plate 21, a sliding groove 221 is vertically arranged on one side of the vertical plate 22, the sliding block 3 is slidably arranged in the sliding groove 221, the cutter supporting block 4 is arranged at the upper end of the sliding block 3, and a through hole 41 which is matched with a cutter 5 is formed in the cutter supporting block 4.

The cutter cooperation in this embodiment can increase the area of contact of cutter and cutter supporting shoe in the through-hole of cutter supporting shoe, and cutter stability is good, reduces or avoids the cutter to remove or rock at the in-process of polishing, promotes the precision of polishing.

In this embodiment, the slider can reciprocate relatively the spout, conveniently adjusts the upper and lower position of cutter supporting shoe, makes the upper and lower position of cutter supporting shoe and cutter corresponding.

The flat plate of the embodiment can move horizontally, and the horizontal position of the cutter supporting block can be adjusted, so that the center of the cutter corresponds to the center of the through hole of the cutter supporting block.

Preferably, the top of the tool supporting block 4 is provided with a notch groove 42 along the extending direction, and the notch groove 42 extends downward and is communicated with the through hole 41 of the tool supporting block 4.

This embodiment is through setting up the breach groove, avoids stress concentration.

Preferably, the upper end of the sliding block 3 is provided with a slotted hole (not shown in the figure) with a trapezoidal cross section, and the bottom of the cutter supporting block 4 protrudes downwards to form a boss 43 matched with the slotted hole.

In the embodiment, the lug boss is matched with the strip-shaped slotted hole with the trapezoidal cross section, so that the structure is simple, and the matching is reliable and stable.

Preferably, the sliding block 3 is provided with a plurality of through screw holes 31 at intervals along the extending direction thereof, and each screw hole 31 is screwed with a fastening bolt (not shown in the figure).
