Description

[Detailed Description of the Invention] The present invention relates to a tool set gauge for a cutter grinder, and more specifically, to a cutter set gauge for a cutter grinder, which is used for positioning to set the relative position between the cutter and the grindstone during sharpening. .

Conventionally, in the above-mentioned cutter set gauge, as shown in FIGS. 1A and B and FIG. It is known that the gauge main body a is provided with stepped portions e and f for thick blade and thin blade set positioning at both ends of the gauge body a, respectively.

Thus, in order to fix the cutter g, first, the mounting surface b of the gauge body a is attracted to the end surface h' of the tool rest h by the magnet c, and then the cutter g is attached to the tool rest h and one end surface of the gauge main body a. Place it on a′ or a″,
After that, the cutting tool g is moved in the direction of the cutting edge, and the cutting edge is brought into contact with the cutting edge set positioning step part e or f.

However, in order to perform the above operation, after adsorbing the mounting surface b of the gauge body a to the end surface h' of the tool post h, the blade g is pressed against the stepped portion e or f with one hand while being held. Since the holding plate h is held parallel with the other hand and fixed with the tightening bolt i, there is no risk of holding down the cutter g with the hand, and both the holding plate h and the tightening bolt i can be operated with one hand. Therefore, it had drawbacks such as poor workability.

SUMMARY OF THE INVENTION An object of the present invention is to provide a blade setting gauge for a polishing machine which eliminates the above-mentioned drawbacks of the prior art and allows easy and safe blade setting.

The present invention will be described in detail below based on one embodiment shown in the drawings.
As shown in the figure, the gauge body 2 has a mounting surface 4 for the end surface 3a of the tool rest 3, and on both sides thereof, stepped portions 5 and 6 for positioning the cutting edge set for thick blades and thin blades are respectively provided on a flat surface. A magnet 10 is attached to the gauge body 2 so that adsorption force is applied to the mounting surface 4 and both end surfaces 7 and 8 on which the cutter 9 placed facing the mounting surface 4 is mounted. 2
It is constructed by being buried in a state where it is clamped between two iron plates 11, 11.

Here, since the gauge body 2 is integrally molded from a non-magnetic material such as plastic or aluminum, the magnet 10 and iron plates 11, 11 in such a case are removed when the gauge body 2 is molded. It is best to bury it with an insert.

The tool rest 3 is pivotally mounted with a fulcrum shaft 15 to a bracket 14 of a table 13, which is placed on a bed 12 so as to be able to reciprocate in the left and right direction by means of a rack and pinion (not shown). By tilting it, the cutting edge of the knife 9 can be sharpened at an angle suitable for the purpose, and by tilting it toward the front as shown by the solid line in FIG. 4, the knife 9 can be attached and detached. .

Further, the cutter 9 is provided so as to be fastened to the tool rest 3 by a cutter presser plate 17 and a tightening bolt 18 .

In the above configuration, in order to place the cutter 9 on the tool rest 3 for polishing using this, first, the mounting surface 4 of the gauge body 2 is attached to the end surface 3a of the tool rest 3 by the attraction force of the magnet 10. Let it absorb.

At this time, depending on whether the blade to be polished has a thick blade or a thin blade, the stepped parts 5 and 6 are oriented toward the blade mounting surface 3b of the tool rest 3, and the side end surface 7 or The gauge body 2 is attracted to the tool rest 3 so that 8 is flush with the tool mounting surface 3b.

Next, the blade 9 is placed on the mounting surface 3b of the tool rest 3 and the set side end surface of the gauge body 2, and the blade edge is brought into contact with the stepped portion (the illustrated example shows the case of a thick blade).

As a result, the cutter 9 is moved to the side end surface 7 of the gauge body 2.
The magnet 10 is attracted and held in the above-mentioned state by the attraction force of the magnet 10.

Therefore, when the cutter 9 is then tightened with the tightening bolt 18 via the cutter retaining plate 17, it is no longer necessary to press and hold the cutter 9 against the set gauge 1.

Further, the set gauge 1 can be easily removed by sliding, for example, toward the end surface 3a of the tool rest 3 or toward the cutting edge of the cutter 9.

Although FIG. 4 shows the case where a thick-edged knife is fixed, the case where a thin-bladed knife is fixed is also the same as described above.

As explained above, by using the cutter set gauge of the polishing machine according to the present invention, there is no need to press and hold the cutter 9 against the set gauge 1 with one hand, so there is no danger when placing the cutter 9 in place. is adsorbed and held on the side end surface 7 or 8 of the gauge body 2, making positioning easy.
7 and the tightening bolt 18 can be operated by both hands, which has the effect of greatly improving the safety and operability of setting cutlery using this type of setting gauge.
