[Lockball contents for carrying out the invention]
Hereinafter, the angle adjusting device of the milling cutter according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
Figure 2 is a perspective view of a milling cutter according to an embodiment of the present invention, Figure 3 is a perspective view showing a separate milling cutter of Figure 2, Figure 4a is an enlarged front cross-sectional view of the milling cutter of Figure 2, Figure 4b is in Figure 4a It is a cross sectional view of the state which rotated the rotation member, and FIG. 5 is an enlarged side sectional view of the milling cutter of FIG.
An angle adjusting device of the milling cutter according to an embodiment of the present invention is a fan-shaped rotating member 20 and the rotating member 20 which is installed to be rotated by a screw shaft 30 on the upper side of the head portion 10 and the head portion. In the angle adjusting device of the milling cutter comprising a cutter blade 40 attached to the side, the gear teeth 22 and the arc surface and the surface formed at regular intervals on the arc surface 21 of the rotating member. The exposure hole 12 is formed in the middle portion of the arc contact surface 11 of the head portion in contact, and the coupling hole 13 and the coupling hole in which the upper portion of the intermediate portion is formed through the head portion horizontally through the exposure hole. Coupled with the outer peripheral surface is characterized in that it further comprises an adjustment member 50 having a worm 51 that is exposed through the exposure port is engaged with the gear teeth.
The adjusting member 50 is in the form of a shaft having a step 52 formed by making the diameter of the front and rear ends 50a smaller than the diameter of the worm 51, and a portion of the outer circumferential surface of the worm is exposed. It is selectively engaged with the gear teeth 22 of the rotating member 20 through.
The diameter of the coupling hole 13 to which the adjustment member 50 is coupled is proportional to the diameter of the worm 51, and the diameter of the rear side portion 13a of the coupling hole is formed in proportion to the diameter of the rear end of the adjustment member. .
Therefore, when the adjusting member 50 is inserted and coupled through the front side of the coupling hole 13, the stepped portion 52 of the rear end is walked on the inner end of the rear side 13a so that the rear end 13a is not separated from the rear side.
