く。The clamper 5 locks the half-moon presser foot 5a on the end face of the cutter, and tightens the clamp bolt 5b in this state. When removing the cutter, the bolt 5b is loosened and the half-moon presser foot 5a is rotated halfway. Release the engagement with the cutter.
【０００５】キー４とキー溝６は、カッタの高精度芯出
しのために４箇所の分割誤差を０．０２ｍｍ以内とし、
それ等の幅も百分台の公差に管理されている。The key 4 and the key groove 6 have a division error of 0.02 mm or less at four locations for high-precision centering of the cutter.

嵌合がきつくなっているため、着脱がスムーズにいかな
い。The mounting mechanism shown in FIG.
Since the key 4 and the key groove 6 are fitted with each other with high precision, it is necessary to remove the cutter so that the key 4 is not twisted, and it is originally not easy to remove the cutter. The cutting heat expands and the fitting with the key groove 6 becomes tight, so that the attachment / detachment cannot be performed smoothly.

あった。The mounting device disclosed in Japanese Patent Application Laid-Open No. 6-143018 also has a structure in which the thickness of the outer periphery of the cutter is reduced so that this portion is housed in the corresponding seat groove of the adapter, and therefore the overall rigidity of the cutter is reduced. In addition, although a lock mechanism for maintaining the coupled state of the hearth coupling is convenient, there is a problem that the structure is complicated and the cost increases.

る構成を採用したのである。In order to solve the above problems, in the present invention, a plurality of splines are provided on the outer peripheral portion of the pin mirror cutter in place of the conventional tsuba, and the inner peripheral portion of the adapter is conventional. A spline groove that replaces the seat groove is provided in correspondence with the spline, and the spline and the spline groove are tapered so that the front side in the cutter insertion direction with respect to the adapter is gradually narrowed to fit the two The key and key groove are omitted.
【００１２】なお、スプラインとスプライン溝のテーパ
角は５°〜６０°、より好ましくは２５°〜４０°の範
囲にあるのが望ましい。The taper angle between the spline and the spline groove is preferably in the range of 5 ° to 60 °, more preferably 25 ° to 40 °.

成されるものなどを好適に利用できる。As the clamper for fixing the pin mirror cutter to the adapter to maintain the fitted state, the clamper composed of the half-moon presser foot and the clamp bolt mentioned above, and the outer peripheral surface of the spline fitted in the spline groove are used. A wedge configured to be press-fitted between the adapter and a wedge propelling screw in which one end side is screwed into the adapter and the other end side of the reverse screw is screwed into the wedge can be preferably used.

ンをスプライン溝の中心に移動させる求心力が生じ、こ
の力でカッタが傾きなく高精度に芯出しされる。When at least three splines are arranged at equal intervals in the circumferential direction and the splines are taper-fitted to the spline grooves at the corresponding positions, the centripetal force that moves the splines to the center of the spline groove at each fitting portion is generated. This force causes the cutter to be accurately centered without tilting.

い。Also, spline is a kind of key,
In the present invention, since the spline and the spline groove are taper-fitted to each other, when the spline thermally expands, a component force for pushing the spline out of the groove is generated in the taper fitting portion, and as the spline comes out, a gap between the spline groove and Enlargement, therefore, the fitting does not become tight immediately after cutting.

の厚みをアダプタ厚と同じにしてカッタの全体剛性を高

小さくして軽量化を図ることが可能になる。Further, if the spline and the spline groove are fitted together, it is not necessary to reduce the wall thickness of the cutter outer peripheral portion, and it is possible to increase the overall rigidity of the cutter by making the thickness the same as the adapter thickness. If the rigidity is the same as the conventional one, the cutter thickness can be reduced to reduce the weight.

てくるので先に述べた範囲の数値にしておくのがよい。If the taper angle of the spline and the spline groove is too small, the key becomes close to the conventional key having a taper angle of 0 °, so the fitting becomes tight and the effect of improving the detachability is weakened. There is a risk that the cutter will come loose because it is too loose, so it is better to set the value within the range described above.
【００１８】また、スプラインの外周部にくさびを圧入

高い。Further, the clamper of the type in which the wedge is press-fitted into the outer peripheral portion of the spline can omit the seat on the cutter side for locking the meniscus presser, and the effect of maintaining the rigidity of the cutter is higher.
