この考案は複数のブレードを本体の外周に組付
けた組立ホブに関する。[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an assembled hob in which a plurality of blades are assembled around the outer periphery of the main body.

固に取り付けたものがあつた。 Furthermore, as disclosed in Japanese Utility Model Application Publication No. 58-136223, the blade is fixed by filling the through hole with adhesive, inserting a feather key, or pouring a low melting point metal such as lead. There was one that was firmly attached to the main body.

た。(Problem to be solved by the invention) However, in the case where the adhesive F is filled in the through hole 7, it is convenient to increase the cross-sectional area of the through hole in order to facilitate the filling of the adhesive. Since the shear strength of the filler is low, an increase in the cross-sectional area of the adhesive will result in a decrease in the strength of the hob. On the other hand, if the cross-sectional area of the through-hole is made smaller, the adhesive may not be sufficiently spread to every corner of the through-hole, and the strength of the hob will also be insufficient in this case. Furthermore, in the case where the feather key was inserted into the through hole 7, the key became loose, causing looseness between the blade and the main body, and vibration of the blade. Those in which low-melting point metal was poured had a problem with the rigidity of the cast metal, and there was a risk that the blade body would come loose.
この考案は、接着剤の充填を容易にし、しかも
充填された接着剤のせん断強度の弱さの影響を少
なくした組立ホブを提供することを目的とする。 The object of this invention is to provide an assembly hob that facilitates the filling of adhesive and reduces the influence of the weak shear strength of the filled adhesive.

とによつて上記の問題点を解決した。(Means for solving the problem) This invention involves assembling a multi-cutting blade into a plurality of grooves drilled on the outer periphery of the main body, and attaching a cutting edge blade with a multi-tipped blade to the rake face side of the base of the blade and the groove wall surface in contact with the rake face side of the base of the blade. This is an assembly hob in which a longitudinal through hole is bored between the holes and adhesive is filled in the through hole, and the through hole is filled with adhesive and a rod-shaped member having a smaller cross-sectional area than the through hole. Thus, the above problems were solved.

孔の隅々まで行き渡る。(Embodiment) Next, an embodiment of this invention will be described with reference to the drawings. As shown in FIGS. The base 8 of the blade 3 is incorporated. The cutting blade 3 has a multi-mounted cutting edge 9, and as shown in an enlarged view in FIG. 3, a V-shaped groove 10 is formed on the rake face 6 side of the base 8 of the blade. The above-mentioned V-shaped groove 10 is formed on the wall surface 5 of the installed groove 2.
A groove 11 corresponding to the groove 11 is formed, and a through hole 7 is formed by both grooves 10 and 11. Further, the through hole 7 is filled with filler adhesive F. For this reason, the adhesive spreads to every corner of the through hole, increasing the adhesive effect. Next, a rod-shaped member 12 having a smaller cross-sectional area than the through-hole 7 is inserted. For this purpose, the adhesive spreads to every corner of the through-hole.

ことはない。(Effects) As described above, this invention has a through hole 7 provided between the groove 2 formed in the main body 1 and the cutting blade 3.
Since the adhesive and the rod-like member having a smaller cross-sectional area than the through-hole were filled in the through-hole, it became possible to increase the cross-sectional area of the through-hole, and filling the adhesive became easier. Moreover, since the adhesive is spread to every corner of the through-hole by filling the rod-shaped member into the through-hole, adhesion is reliably performed. Furthermore, if a large amount of adhesive is filled into the through-hole 7 having a large cross-sectional area, the problem of the adhesive's weak shear strength will not occur because the rod-shaped member 12 will act as a reinforcing material. .
