Therefore, the height of the cutting blade 5 with respect to the optical fiber 2 needs to be appropriately adjusted. The mechanism for adjusting the height of the cutting blade 5 will be described. The cutting blade 5 is rotatably supported by a shaft 8 on a blade holder 7, and when the adjusting screw 10 screwed near the tip of the blade holder 7 is turned. The blade holder 7 pivots about a shaft 9 parallel to the shaft 8, whereby the cutting blade 5 moves up and down, and the height of the blade (the position of the cutting edge at the highest point of the cutting blade 5) is adjusted.

The height of the cutting blade 5 was adjusted by turning the adjusting screw 10 so that the distance would be appropriate. After the height adjustment is completed, when the fixing plate 14 is fixed to the slide base 15 with the screw 12 (see FIG. 3), the adjustment screw 10 does not rotate, and the blade holder 7 is fixed to the slide base 15, and the blade height is fixed. The adjustment work is completed.

Good cutting can be performed by using an unused cutting edge. In order to fix the circumferential position of the cutting edge, the cutting blade 5 is provided with several fixing holes 5a on the circumference, and a set screw 16 (see FIG. 3) is used at the position of the hole 5a. Thus, the circumferential position of the cutting edge is fixed. As described above, the cutting edge is sequentially rotated at the circumferential direction interval of the set screw 16 to use a new cutting edge portion, and the unused portion of the cutting edge disappears after one rotation, so that the cutting blade 5 needs to be replaced.

があった。When the cutting blade 5 is replaced in the optical fiber cutting device 1, the height of the blade must be adjusted. The reason for this is that in FIG. 8, to make the outer diameter D constant while polishing the cutting edge of the cutting blade 5 so as to have a certain angle θ, it is difficult to perform polishing because
This is because it is very difficult, and the outer diameter D of the cutting blade 5 varies. However, as described above, the conventional method of adjusting the height of the blade by turning the adjustment screw 10 while visually observing the blade edge with the microscope 3 or the like is cumbersome, poor in workability, and the accuracy of the height adjustment is poor. There was a problem that variation might occur.

後方に回転させて、退避させておく。In the present invention, a blade height adjusting member 33 is used as an auxiliary tool for adjusting the height of the cutting blade 5 with the adjusting screw 10.
Is provided. The blade height adjusting member 33 is rotated by 180 ° with respect to a shaft 34 passed between the stages 31 and 32 on which the receiving bases 3a and 4a, which are lower portions of the clamps 3 and 4, are mounted.
A cutting blade positioning portion 33b, which is rotatably mounted and has a groove 33a into which the cutting edge of the cutting blade 5 is formed, is provided at the distal end. When the blade height adjusting member 33 is rotated forward as shown by the solid line, as shown in FIG. 5, the blade height adjusting member 33 abuts on the upper surfaces of the stages 31 and 32,
It will always be at a certain height. In this state, as shown in FIG. 6, the slope of the cutting edge of the cutting blade 5 is brought into contact with the groove 33a of the blade height adjusting member 33 (the edge of the groove 33a) so that the blade height is initially set. It can be the same height as the state. When replacing with a new cutting blade, even if the outer diameter of the cutting blade is different, make the cutting edge of the cutting blade to have a certain angle θ, and use this method to adjust the height of the blade. It can be done easily. The blade height adjusting member 33 is retracted by rotating backward about the shaft 34 as shown by a two-dot chain line in FIG. 1 except when performing the blade height adjusting operation.

Since the height of the cutting blade 5 is determined by the dimension of B and the angle θ of the slope 5b of the cutting edge of the cutting blade 5, the blade height adjusting member 33 is set in advance. That is, after correctly adjusting the height of the cutting blade 5 by visual observation using a microscope or the like in the same manner as in the above-described conventional method, the slope portion 5b of the cutting edge of the cutting blade 5 becomes the groove 33a of the blade height adjusting member 33. The dimensions of A and B are adjusted so as to hit. Thereafter, the height of the cutting blade 5 does not need to be visually observed accurately using a microscope or the like, and the height can be adjusted by a simple operation of abutting against the groove 33a of the blade height adjusting member 33. I can do it. As a method of adjusting the dimensions of A and B, A
Alternatively, there is a method in which either one of the members B is kept constant and several types of adjustment members 33 whose dimensions are slightly different from the other are prepared, and are replaced with just the right ones.
