Abstract

PURPOSE:To easily regulate the edge width directional position of a cutting edge tip in, for example, a gear cutter having a cutting edge consisting of a right edge and a left edge. CONSTITUTION:A cutting edge tip 3 having a right edge 3a is brought into the standard surface 10 of a face plate 6a, and a cutting edge tip 3 having a left edge 3b is brought into contact with the standard surface 10 of a face plate 6a. Face plates 6 make contact with a tool body 1 by the inclined surfaces 11 inclined in the outer circumferential direction. Since the distance between the two face plates 6 can be changed by the rotation of the face plates 6, the edge width directional regulation of the cutting edge tips 3 can be easily performed at once.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling tool provided with an adjusting mechanism, and more particularly to an adjusting mechanism for adjusting a position of a cutting edge tip in a width direction in a gear cutting cutter or a side cutter.

[0002]

2. Description of the Related Art As a conventional method for adjusting the position in the blade width direction,
An example of the gear cutting cutter is shown in FIG. In this example, the cutting edge tip 3 is incorporated in the mounting groove 2 of the tool body 1, but the cutting edge tip 3 has two shapes, and the cutting edge tip 3 of the right blade 3a or the left blade 3b is included. Are alternately incorporated in the outer peripheral direction so as to form a cutting edge having a continuous rotation locus. Tool body 1 and cutting tip 3
A seat 4 is mounted between the and, and is fixed to the tool body 1 with a countersunk screw 5. The outer diameter of the gear cutting cutter is adjusted by the thickness of the sheet 4.

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 chip 3 having the right blade 3a is brought into contact with the face plate 6a, and the cutting edge chip 3 having the left blade 3b is brought into contact with the face plate 6b to determine the position in the blade width direction. 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 conventional method of adjusting the position in the width direction of the blade as described above, the face plates 6 having different thicknesses depending on the number of adjustments, or the number of face plates 6 depending on the adjustment amount, may be adapted to each of them. It is necessary to prepare the sheet 4 in advance.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and is one in which adjustment is continuously performed without replacing the face plate. That is, a swivel face plate is attached to at least one side face of the tool body, and one side face of the tool body and the face plate are brought into contact with each other by a sloped surface that is partially inclined in the circumferential direction. The position of the cutting edge tip in the blade width direction is determined by abutting and fixing the cutting edge tip on the face plate thus mounted.

[0006]

[Operation] Since one side surface of the tool body and the face plate are in contact with each other with a sloped surface inclined in the circumferential direction, the turning movement of the face plate in the circumferential direction is caused by the effect of the slope. Converted to the movement of the face plate in the blade width direction. Therefore, the cutting edge tip, which abuts and is fixed to the face plate, can also move in the width direction. The movement in the blade width direction is continuous within the swivelable range of the face plate.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings.

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 blade tip 3, and the right blade 3a and the left blade 3b are alternately incorporated in the outer peripheral direction to form a cutting blade having a continuous rotation locus. A sheet 4 is provided between the tool body 1 and the cutting edge tip 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 of the cutting edge tip 3 in the blade width direction is determined by the distance between the two ring-shaped face plates 6. That is, the cutting edge chip 3 having the right blade 3a is brought into contact with the face plate 6a, and the cutting edge chip 3 having the left blade 3b is brought into contact with the face plate 6b to determine the position in the blade width direction. When the position is determined, the face plate 6 is fixed by the bolt 7. Also,
The cutting edge tip 3 is pressed and fixed in the mounting groove 2 by a wedge action by operating the screw 9 for screwing the wedge component 8 into the tool main body 1 and causing it to sink.

As shown in FIG. 4, the face plate 6 has a reference surface 10 parallel to the opposite surface, a sloped surface 11 inclined from the reference surface 10 along the outer periphery in a direction in which the thickness gradually decreases, and at the thinnest portion. One parallel parallel surface 12 is made into one group, and this face plate 6
And the same number of groups as the number of cutting edge chips 3 abutting on the above.

On the other hand, the side surface of the tool main body 1 has a sloped surface with the same inclination angle and inverted concavities and convexities so as to mesh with the sloped surface 11 of the face plate 6, and the distance from the tool main body 1 can be changed by turning the face plate 6. It has become. The face plate 6 is provided with an elongated hole 13 so as to be rotatable, and when the position of the face plate 6 is determined, it is fixed to the tool body 1 by tightening a bolt 7. The cutting edge tip 3 is fixed by abutting against the reference surface 10 of the face plate 6. The face plate 6 is graduated so that the adjustment amount can be known in relation to the inclination angle of the sloped surface 11.

In this embodiment, the face plates 6 are mounted on both sides, but an adjusting mechanism for only one side may be used depending on the method of use. When it is desired to make the adjustment range large and to make the adjustment amount fine, it is also possible to lengthen the sloped surface 11 and bring the cutting edge tip 3 into contact with the sloped surface 11.

[0013]

As described above, according to the present invention, in a rolling tool such as a gear cutting cutter or a side cutter, a dimensional change due to fine adjustment of the blade width or re-grinding of the cutting tip without changing the face plate. Will be able to support
The setting time can be shortened because it can be easily adjusted each time.
