Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an optical fiber cable connector end face polishing machine for polishing a connector end face in optical fiber terminal processing.

[Conventional technology]

Conventional optical fiber cable connector end face polishing machines include a system that works individually for each cable, a system that fixes a plurality of cables to a single holder, and the like. The method of polishing each piece has restrictions on polishing time, and even when several machines are working at the same time, the degree of finish may vary depending on the application of abrasive and the difference in polishing time for rough polishing, medium polishing, and final polishing.
There is a limit to the amount. Furthermore, abrasives are required for each connector, and therefore the abrasives are often consumed.

In addition, when polishing multiple connectors fixed to one holder, it takes a lot of time to attach and detach them, and it takes a lot of time to attach and detach them, and it takes a lot of time to attach and detach them. It is difficult to attach the surfaces (surfaces) uniformly without unevenness, and therefore it is difficult to equalize the load. It is not easy to polish uniformly. For this reason, after polishing for a certain period of time,
The method involves inspecting the polished surface using a microscope or the like before removing it, which is extremely troublesome work. Also,
Since each connector is fixed to a holder, it is not possible to arbitrarily set the amount of polishing of each connector end face.

Furthermore, as a device for fixing and polishing multiple connectors on one holder, after attaching the connectors to the holes of the holder, one leaf spring is attached to all the connectors, and this leaf spring is held down with a retaining screw. A device has been proposed that applies equal surface pressure to all connectors by pressing and fixing them onto the holder.
issue). However, even in this case, it is difficult to attach the end faces of each connector uniformly without unevenness, and among the attached connectors, the one that protrudes the most is polished the most, and the other connectors are polished less, resulting in multiple connectors being polished. It is difficult to polish uniformly. Further, since each connector is fixed to the metal holder by a single leaf spring, it is not possible to arbitrarily set the amount of polishing of each connector end face.

[Purpose of invention]

In FIG. 1, a terminal-treated optical fiber cable 3 is hardened with an epoxy resin inserted into a ferrule 1, and further crimped and fixed with a collar 2 to form an optical fiber connector. In this state, the end face is uneven due to the epoxy resin and fiber protrusion. Therefore, in order to polish this surface, the optical fiber connector shown in Fig. 1 is attached to the polishing machine shown in Fig. 3, but in this invention, considering the ease of attachment and detachment to the polishing machine, the optical fiber connector shown in Fig. 2 is shown. Correct chuck 4 is installed.

In FIG. 4 showing the details of the holder installation state in FIG. 3, 13 is a shaft that is inserted into a hole provided at a position eccentric from the rotational center axis of the swing spindle 8 and is driven to swing. is connected to a shaft rotation stopper 9 so that the shaft 13 itself does not rotate due to the rotation of the swing spindle 8. 14 is a slide bearing that slides and supports the shaft 13 in the axial direction; 15 is a collection chuck 4;
This is a slide bearing that slides and supports the shaft in the axial direction. Reference numeral 18 denotes a fixed body for rotatably supporting the polishing disk 6, rotating spindle 7, and swinging spindle 8, and it is sufficient if they are connected and fixed to an appropriate place such as the frame of the polishing machine.

When polishing the connector end face, use the second
A plurality of collect chucks 4 shown in the figure are installed in respective axial holes provided in an annular position of the holder 5.
The polishing disk 6 is rotationally driven by a rotary motor 10 via a rotary spindle 7. Note that the lower end peripheral edge portion 17 of the rotating spindle 7 is connected to the rotating motor 10 via a gear 16. The holder 5 is horizontally oscillated by a oscillating spindle 8 via a shaft 13. That is, the swing spindle 8 supported by the fixed body 18 is provided with a hole extending in the axial direction at a position eccentric from the rotation center axis when rotated by the swing motor 11, and the shaft 13 is inserted into the hole. By rotating the swing spindle 8 in this state, the holder 5 and the shaft 13 are driven to swing in the horizontal direction.

A protrusion 4a is provided on the outer periphery of each collect chuck 4, and a ring-shaped weight 12 having an inner diameter that fits into the straight body of the collect chuck 4 is held on the protrusion 4a. This weight 12 allows each connector end face to be polished by the polishing plate 6.
It is made so that it is pressed against the In this way, the weights 12 are independent from each other and are not connected to other weights, and the collect chuck 4 is not fixed to the holder 5, so the collect chuck 4 with the weight 12 attached moves inside the hole of the holder 5. It can move up and down freely, and each connector end face is pressed against each other by an independent weight 12. Note that the surface pressure of the pressure means is applied by adjusting the weight 12 in advance.

In this way, the optical fiber cable connector end face polishing machine of this embodiment can polish multiple connectors independently and apply adjustable surface pressure simultaneously, so the amount of polishing for each connector can be set at a constant level or arbitrarily. , polishing efficiency can be greatly improved.

With a simple structure, the connector can be easily attached and detached from the polisher, and the work can be performed with high efficiency without requiring any skill.

[Effect of idea]

As described above, the optical fiber cable connector end face polishing machine of the present invention holds independent ring-shaped weights on the projections on the outer periphery of each collect chuck, and uses the respective weights to adjust the surface pressure of each connector end face. By allowing the decision to be made, the following remarkable effects can be achieved.

(1) The connector can be easily attached and detached from the polishing holder.

(2) If the weight of each weight is constant, the amount of polishing can be kept constant because the collector chuck can be attached without being fixed to the polishing holder and the surface pressure on each connector end face can be constant. I can do it.

(3) If the weight of each weight is changed, the amount of polishing can be set to be proportional to the weight of each weight, making it possible to polish multiple connectors at the same time with high efficiency. .
