Handling jigs with levers and pushers, mutual temporary positioning means between the mounting base and handling jigs, locking mechanisms for jigs with horizontal drive means and positioning reference blocks (all mentioned above), etc. can be adopted. It is. The handling jig mentioned here temporarily fixes the optical connector by lightly biting it with a lever, and corrects misalignment by pressurizing it with a pusher. On the other hand, the mutual temporary positioning means roughly determines the position of the handling jig, and the locking mechanism accurately positions and fixes the mounting base and handling jig, and at the same time swings the lever to increase the clamping force of the optical connector. . Therefore, even if the depth of cut is large, the stability and precision of machining can be improved using these tools.

(due to the use of a completely non-existent locking mechanism 20)
The handling jig 2 connects the spherical part at the tip of the shaft body 25 to the round hole 1.
5 and perform temporary positioning. Next, when the mounting base 8 is moved backward using the cylinder 18, the handling jig 2 also moves together, and the back surface of the jig body 21 is aligned with the positioning reference block 19.
As a result, the jig 2 is accurately positioned by the block 19. After this, the cylinder 18 continues to pull the mounting base 8, so that the contact pressure between the spherical portion at the tip of the shaft body 25 and the inner surface of the round hole 15 increases, and the handling jig 2 is locked onto the mounting base 8. Furthermore, since a rotational moment is applied to the lever 23 through the shaft body 25 when the mounting base 8 is retracted, the lever 23 rotates in the clamping direction to firmly tighten the optical connector A. Therefore, even if the depth of cut is a little large, the optical connector A will not move during polishing.

Further, the feed rate during polishing by the feed table 47 is set to about 0.1 to 10 mm/sec, but the properties of the polished surface become better as the feed rate is smaller. According to this grinding and polishing section 4, it is possible to perform rough polishing at the same time as cutting the excess length of the optical fiber protruding from the tip of the optical connector by just one pass on the abrasive surface.

調整して自由に変えることができる。Parts of FIGS. 12, 13 and 15 show the final polishing section 5. As shown in FIG. This final polishing section 5 is operated by a motor 52.
(FIG. 12) has a polishing head 51 that is rotated. It also includes a locking mechanism 20 for positioning and fixing the handling jig 2 on the mounting base 8 (this has the same structure as the one described above), a motor 55 (FIG. 16), and a traverser 56 for feeding in the Y-axis direction. It has a table 57 and a nozzle 58 for applying polishing liquid to the polishing surface of the polishing head. The mount 8 is installed on a mount support table 53 that is slidable in the X-axis direction on a feed table 57. The table 53 also moves the locking mechanism 20 in the X-axis direction. This table 53 is provided with a spring 54 (FIG. 15) with a load adjustment mechanism between it and the feed table 57 to bias it toward the polishing head 1, and is set in the handling jig by the force of the spring. Optical connector A is pressed against the polished surface (this pressure is, for example, 0.1
~1.5kg/cm2) Polished. 59 is a cylinder that pulls back the mount support table 53 against the force of the spring 54. The polishing time can be freely changed by adjusting the operation timing of this cylinder.

The polishing sheet 51a facing d performs polishing on a portion along the flat front surface 51e. The feeding mechanism 51b may be one that continuously feeds the polishing sheet 51a little by little in conjunction with the rotation of the head, or one that uses a drive source separate from the head to perform similar feeding or intermittent feeding. Also, instead of rotating the head 51, the polishing sheet 51
Polishing can also be performed by continuous feeding of a and reciprocating motion of the table 57 in the Y-axis direction.

研磨の研磨時間を個々に最適値に定めることができる。Parts of FIGS. 14 and 15 show the buffing section 6. As shown in FIG. This buff polishing section 6 rotates a buff 61 with a motor 62, presses the optical connector A against the buff in the same manner as the final polishing section 5, and advances polishing while feeding in the Y-axis direction. For feeding, the aforementioned feeding table 57 is shared in order to simplify the device (see FIG. 16). Furthermore, the pressing of the optical connector A against the buff and the pulling back of the mount support table 63 provided on the feed table 57 are performed independently of the final polishing section 5 by providing a spring 64 with a load adjustment mechanism and a return cylinder 69. I am trying to do it in this way. By doing so, the polishing times for final polishing and buff polishing can be individually set to optimal values.
