Problems solved by technology

[0015] The problem to be solved is that the grinding pressure is not stable because of the structure that only relies on the coil spring to impart the grinding pressure, and the improvement of the grinding accuracy is limited after all. The polishing device that can apply the established processing pressure cannot be simply used for grinding the optical fiber ferrule.

Embodiment 1

[0145] [Outline of the appearance of the optical fiber ferrule end face grinding device]

[0146] figure 1 It is a perspective view showing main parts of the optical fiber ferrule end face polishing device. figure 2 It is a side view showing the main part of the optical fiber ferrule end face grinding device. image 3 It is a perspective view of the main part of the optical fiber ferrule end face polishing device viewed from the bottom side. Figure 4 It is a perspective view of the main part of the optical fiber ferrule end face polishing device viewed from the other side below.

[0147] It should be pointed out that in the following description, front, rear, left, right refer to front, rear, left, right when viewing the end surface grinding device from the front, and up and down refer to up and down when the grinding disc of the end surface grinding device is directed upward.

[0148] Such as Figure 1 to Figure 4 As shown, the optical fiber ferrule end face grinding de...

Embodiment 2

[0400] Figure 31 It is a schematic perspective cross-sectional view showing main parts of the optical fiber ferrule end face polishing device according to the second embodiment. It should be pointed out that since the basic structure is the same as that of Embodiment 1, the same reference numerals are given, and repeated descriptions will not be repeated. in addition, Figure 31 Structures and labels not given in, see Example 1 Figure 9 Wait.

[0401] Figure 31 The end face grinding device 1E is configured in such a way that the driving force of the rotational output is directly transmitted to the thrust ring 33E as a pressing force through the end face cam 151 .

[0402] The grinding disc guide support portion 31E includes a thrust ring 33E and a guide ring 153 .

[0403] The above-mentioned thrust ring 33 has a structure that enables the above-mentioned grinding drive of the grinding disc 5 and transmits the pressing force as a part of the pressing force transmission...

Embodiment 3

[0419] Figure 32 It is a schematic side view showing a holding part guide support part and a pressing force transmission mechanism according to Embodiment 3, in which a part of the optical fiber ferrule end face polishing device is shown in cross section. It should be pointed out that since the basic structure is the same as that of Embodiment 1, the same reference numerals are given, and repeated descriptions will not be repeated.

[0420] In the end face grinding device 1F of this embodiment, the support 9F can move forward and backward relative to the grinding disc 5 in the up and down direction, so as to adjust the grinding pressure.

[0421] Therefore, in the end surface grinding device 1F of this embodiment, the thrust ring 33F is positioned on the base plate 3F, and the vertical position cannot be changed.

[0422] The end face grinding device 1F of the present embodiment includes a holding portion guide support portion 161 . The holding part guide support part 161 h...

Abstract

Provided is a an end surface polishing device whereby an end surface of an optical fiber ferrule is polished with an adjusted polishing pressure and polishing precision can be enhanced. An end surfacepolishing device 1 for an optical fiber ferrule, for imparting a polishing pressure between a polishing plate 5 driven in polishing by a polishing drive shaft, and an optical fiber ferrule retained by a retaining part 9, and polishing an end surface of the optical fiber ferrule, wherein the end surface polishing device 1 is characterized by being provided with a bearing part for allowing relativerotation about an axis between the polishing drive shaft and the polishing plate 5 and relative movement thereof in the axial direction, a polishing plate guide support part 31 for making advancing / retreating action of the polishing plate 5 with respect to the retaining part 9 in the axial direction possible and movably supporting the polishing plate 5 on a base part 3 in order to impart polishing pressure, a pressing drive source 15 for adjustably outputting a drive force for pressing in order to impart polishing pressure, and a pressing force transmission mechanism 21 for transmitting the drive force outputted from the pressing drive source 15 as a pressing force in the direction of the advancing / retreating action of the polishing plate 5.

Description

technical field [0001] The present invention relates to an optical fiber ferrule end face grinding device for grinding the end face of an optical fiber ferrule. Background technique [0002] Patent Document 1 describes an existing optical fiber ferrule end face grinding device. [0003] In the end face grinding device of Patent Document 1, a holding portion is disposed so as to face the upper portion of the grinding disc. The holding part has a disc-shaped chassis for holding the ferrule, and the chassis is movably supported. With this movable support, a structure in which the chassis is pressed and moved downward is formed. The pressing movement of the chassis is realized by a coil spring disposed at the center portion on the side of the chassis. The coil spring is configured to bias the chassis downward. [0004] Therefore, the end face of the optical fiber ferrule supported by the chassis abuts against abrasive materials such as the abrasive film on the abrasive disk ...
