る。2. Description of the Related Art Among tool holders that are removably mounted on a tool rest or a spindle of a machine tool, there is a tool holder capable of adjusting a mounting position of a cutting tool such as a throw-away tip according to cutting conditions. Are known. FIG. 3 is an explanatory view of a blade tool position adjusting mechanism according to a conventional example of a blade tool position adjusting mechanism, in which a part of a tool holder is broken. The tool holder shown in FIG. 3 is suitable for machining the inner diameter surface of a workpiece, boring, and the like. The tool holder T is a taper shank portion Tc that is inserted into and clamped on a spindle of a machine tool (not shown).
And a flange portion Ta in which a V groove is formed so that it can be gripped by an arm such as an automatic tool changer (ATC), and a shank portion Tb to which the cutting tool S is attached. A cutting tool mounting portion 4 is formed on one end portion (left side in the drawing) of the shank portion Tb, and the cutting tool S is mounted on the cutting tool mounting portion 4 via the cutting tool holder 1 by a mounting bolt 1c. The two side walls 4a, 4a of the cutting tool mounting portion 4 are each formed as a gauge surface. By tightening the mounting bolt 1c in a state where the bottom and side parts of the cutting tool holder 1 are in close contact with the side walls 4a, 4a, the cutting tool 1c is tightened. It is possible to always attach S to the tool holder T accurately. The hole of the cutting tool holder 1 through which the mounting bolt 1c is inserted is formed as an elongated hole, and the mounting position can be adjusted by moving the cutting tool holder 1 along the forward / backward movement axis A parallel to the axis C. There is.

っている。By the way, in the tool holder T having a plurality of cutting tools S on the same circumference, the projecting amounts of the cutting tools S from the tool holder T must be equal. That is, if the amount of protrusion is excessive or the amount of protrusion of each cutting tool S varies, chatter vibration may occur during processing. Such chatter vibration reduces tool life and finishing accuracy, and also causes unpleasant noise. Therefore, it is necessary to finely adjust the mounting position of the cutting tool S to make the protruding amount of each cutting tool S uniform and appropriate. I have to. Therefore, a cutting tool position adjusting mechanism as shown in the figure has been conventionally used. In this cutting tool position adjusting mechanism, the adjusting bolt 1b is screwed into the cutting tool holder 1, and the head portion of the adjusting bolt 1b is inserted into the bottom surface 4 of the cutting tool mounting portion 4.
It is abutted on b. Then, with the mounting bolt 1c lightly tightened, the adjustment bolt 1b is rotated with an adjustment tool such as a wrench, and the blade S is driven by the propulsive force of the screw.
Is pushed to one side of the tool holder T to finely adjust the protrusion amount.

きなくなるという問題がある。However, the conventional blade position adjusting mechanism as described above is suitable for fine adjustment in the direction of increasing the protrusion amount of the blade S, but it is difficult to perform fine adjustment in the direction of decreasing the protrusion amount. There is a problem. That is, when the protruding amount of the cutting tool S is excessively large, the provisional tightening with the mounting bolt 1c is released, and the adjusting bolt 1b is screwed into the cutting tool holder 1 with an appropriate length, and the head of the adjusting bolt 1b is a bottom surface. After pushing the cutting tool holder 1 into the cutting tool mounting portion 4 until it comes into contact with 4b and tightening the mounting bolt 1c again to temporarily tighten it,
The amount of protrusion was finely adjusted by the above procedure. Such work must be performed on all of the cutting tools S, and it takes a lot of time to adjust the mounting position of the cutting tools S, resulting in extremely poor work efficiency and a heavy work load on the worker. Further, the head of the adjusting bolt 1b has a bottom surface 4b.
Since it is formed in a pivot shape so as not to give an eccentric moment to the tool holder 1 by making point contact with the bottom tool 4 to reduce frictional resistance, an indentation is formed on the bottom surface 4b when the head is pressed against the bottom surface 4b. However, if the indentation is formed at a position eccentric from the advancing / retreating movement axis A due to the inclusion of chips, it becomes difficult to bring the side or bottom of the cutting tool holder 1 into close contact with the side walls 4a, 4a. However, there is a problem that the cutting tool S cannot be accurately attached to the tool holder T.

In this state, when an adjusting tool such as a wrench (not shown) is engaged with the engaging portion 3 and the screw shaft 2 is rotated in either direction, the blade holder 1 is moved by screwing in and out of the screw shaft 2. It can be moved along the forward / backward movement axis A. In this case, since the rotation of the square nut 6 is regulated in the notch groove 5 and the movement to one side is regulated by the partition wall 4c, the blade holder 1 is rotated by 2 pitches by rotating the screw shaft 2 once. It can be moved back and forth by a minute (two threads). When the cutting tool S is located at a predetermined position, the cutting tool holder 1 may be pressed against the side walls 4a, 4a and the mounting bolt 1c may be tightened.

に取り付けることができるようになる。Since the present invention is constructed as described above, it has the following effects. By rotating the screw shaft, the cutting tool can be moved in one direction or the other direction along the advancing / retreating axis of movement, making it extremely easy to finely adjust the mounting position of the cutting tool, and adjust the cutting tool position. It is possible to significantly reduce the work time for improving the work efficiency and reduce the work load on the worker.
Also, since the screw shaft and square nut are always located on the forward / backward movement axis, the bottom and sides of the blade holder can be placed in close contact with the side wall of the blade mounting portion, and the blade can always be attached to the tool holder in an accurate state. become able to.
