Field of the Invention The present invention relates to a milling tool provided with an adjusting mechanism, and more particularly, to an adjusting mechanism for adjusting a position of a cutting edge tip in a blade width direction in a gear cutting cutter or a side cutter. About. 2. Description of the Related Art Conventional methods for adjusting the position in the blade width direction include:
FIG. 5 shows an example of a gear cutting cutter. In this example, the cutting edge tip 3 is incorporated in the mounting groove 2 of the tool main body 1. There are two types of cutting edge tips 3 and the cutting edge tip 3 of the right blade 3a or the left blade 3b. Are alternately incorporated in the outer peripheral direction to form a cutting edge having a continuous rotation trajectory. Tool body 1 and cutting edge tip 3
A sheet 4 is mounted between the two and fixed to the tool body 1 by a countersunk screw 5. The outer diameter of the gear cutting cutter is adjusted by the thickness of the sheet 4. [0003] The position of the cutting edge tip 3 in the blade width direction is determined by the distance between two ring-shaped face plates 6. That is, the cutting edge tip 3 having the right blade 3a is brought into contact with the face plate 6a, and the cutting edge tip 3 having the left blade 3b is brought into contact with the face plate 6b, whereby the position in the blade width direction is determined. The face plate 6 is fixed by bolts 7, but the position adjustment of the cutting edge tip 3 in the blade width direction is performed by exchanging with another face plate having a different thickness. [0004] However, in the above-described conventional methods of adjusting the position in the blade width direction, the face plates 6 having different thicknesses by the number corresponding to the adjustment amount can be adapted. In some cases, it is necessary to prepare the sheets 4 in advance. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and is intended to continuously perform adjustment without replacing a face plate. That is, a pivotable face plate is mounted on at least one side surface of the tool body, and one side surface of the tool body and the face plate are configured to abut each other by a slope that is partially inclined in a circumferential direction. The cutting edge tip is brought into contact with and fixed to the face plate mounted in this manner, so that the position of the cutting edge tip in the blade width direction is determined. [0006] One side surface of the tool body and the face plate are partially in contact with each other on a slope inclined in the circumferential direction. Is converted into the movement of the face plate in the blade width direction. Therefore, the cutting edge chip fixed in contact with the face plate can also move in the width direction. The movement in the blade width direction is continuous within the pivotable range of the face plate. Next, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1 to 3 show an embodiment of the present invention in a gear cutting cutter, in which a cutting edge tip 3 is incorporated in a mounting groove 2 of a tool body 1. There are two types of shapes of the cutting edge chip 3, and the right blade 3a and the left blade 3b are alternately incorporated in the outer peripheral direction to form a cutting edge having a continuous rotation locus. A sheet 4 is provided between the tool body 1 and the cutting edge chip 3, and is fixed to the tool body 1 by a countersunk screw 5. The outer diameter of the gear cutting cutter is adjusted by the thickness of the sheet 4. The position in the blade width direction of the cutting edge tip 3 is determined by the distance between the two ring-shaped face plates 6. That is, the cutting edge tip 3 having the right blade 3a is brought into contact with the face plate 6a, and the cutting edge tip 3 having the left blade 3b is brought into contact with the face plate 6b, whereby the position in the blade width direction is determined. When the position is determined, the face plate 6 is fixed by bolts 7. Also,
The cutting edge tip 3 is pressed and fixed in the mounting groove 2 by a wedge action by operating a screw 9 for screwing the wedge part 8 into the tool body 1 to sink the cutting edge tip 8. As shown in FIG. 4, the face plate 6 has a reference surface 10 parallel to the opposite surface, a gradient surface 11 extending from the reference surface 10 along the outer periphery and gradually inclined in a direction of decreasing thickness, and a thinnest portion. A certain parallel squeezing surface 12 is grouped into one group, and this face plate 6
And the same number of the groups as the number of blades of the cutting edge tip 3 that comes into contact with the group. On the other hand, the side surface of the tool body 1 has a slope surface having the same inclination angle and a reversed indentation so as to mesh with the slope surface 11 of the face plate 6. It has become. The face plate 6 is provided with an elongated hole 13 so that it can be turned. When the position of the face plate 6 is determined, the face plate 6 is fixed to the tool body 1 by tightening bolts 7. The cutting edge chip 3 is fixed in contact with the reference surface 10 of the face plate 6. A scale is engraved on the face plate 6 so that the amount of adjustment can be determined in relation to the inclination angle of the inclined surface 11. In the present embodiment, the face plate 6 is mounted on both sides. However, depending on the method of use, an adjusting mechanism on only one side may be used. When a large adjustment range and a small adjustment amount are desired, the inclined surface 11 can be lengthened and the cutting edge chip 3 can be brought into contact with the inclined surface 11. As described above, according to the present invention, in a rolling tool such as a gear cutting cutter or a side cutter, fine adjustment of the blade width or re-grinding of a cutting edge chip without replacing a face plate. Can respond to dimensional changes due to
Since the adjustment can be easily performed each time, the setting time can be reduced.
