Description

Optical fiber cutter with split type independent upper pressing arm structure

Technical Field

The utility model relates to the technical field of optical fiber cutters, in particular to an optical fiber cutter with a split type independent upper pressing arm structure.

Background

Optical fibers are widely applied to the fields of communication, medical treatment, sensors, navigation, and the like, and the main material for manufacturing the optical fibers is high-purity quartz, so that a special method is needed for connecting the optical fibers; at present, two methods are mainly adopted in the engineering field: one is physical connection, i.e., the precise alignment and fixing of the optical fibers to be connected, called cold splicing; the other is to further heat a group of precisely aligned optical fibers at high temperature to reach the melting point of the optical fibers so as to fuse the two core optical fibers, which is called fusion; the radial sections of the optical fibers must be planarized before cold splicing and fusion, and only then the radial sections of the optical fibers can be bonded as two by two as much as possible when aligned, so that light can be effectively transmitted. In the field of communication optical fiber engineering, the optical fiber end face processing tool is an optical fiber cutting knife, and the principle is as follows: the outer circle of the optical fiber is scratched by the blade edge, so that a notch perpendicular to the axis of the optical fiber is formed, and then an external force is applied to expand along the direction of the notch until the optical fiber breaks.

I apply for a full-automatic optical fiber cutting machine in 2022, 8 and 22 days, the application number is 202222206574.7, and the full-automatic optical fiber cutting machine comprises a base, a tool rest, an upper cover, a cutter returning device, a pushing device, a push rod, a positioning pin and the like. The base is provided with a chute for sliding the tool rest, and the tool rest is connected in the chute in a sliding way. One end of the upper cover is hinged with the base, one end of the pushing device is fixedly connected with the upper cover, and the other end of the pushing device extends into the chute through the opening; when the optical fiber is cut, the upper cover is touched, the upper cover is abutted against the ejector rod, the positioning pin slides out of the positioning hole, the pushing device is driven to push the tool rest to move to the first position, and the cutting blade on the tool rest automatically completes cutting of the optical fiber in the moving process.

In the above patent, no manual operation is needed, and full-automatic optical fiber cutting is truly realized, so that the operation steps of the optical fiber cutting machine are simplified, and the working efficiency and the use experience of a user are greatly improved. However, through the use, when the optical fiber cutting machine clamps the optical fiber in the use process, clamping pieces on two sides of the optical fiber cutting machine can effectively clamp the optical fiber when the clamping pieces are required to be kept at the same level, and once the optical fiber cutting machine is damaged by external force or other reasons, the situation that the heights of two sides of the optical fiber cutting machine are different can occur, one side clamps the optical fiber, but the other side does not clamp the optical fiber, so that the optical fiber cutting machine cannot cut normally can be caused. Therefore, the utility model fundamentally solves the problem that clamping cannot be performed when heights of two sides of the optical fiber cutting machine are different. The utility model has a split independent upper pressing arm structure, and the left upper pressing arm and the right upper pressing arm are not integrated, are not linked, but are independently movable. The two independent upper pressing arms are respectively corresponding to the lower pressing plates of the cutter bases, and respectively clamp the optical fibers of the two independent upper pressing arms in the clamping process, and the two independent upper pressing arms work independently and do not interfere with each other. The two independent upper pressing arms can be not at the same height, and even under the condition that the heights of the left side and the right side of the optical fiber cutting machine are different, the optical fibers on the two sides can still be firmly clamped through the split independent upper pressing arms, so that the cutting is completed. The practical significance is that the cutter can still complete cutting well even if the heights of two sides of the cutter are different under the action of external force or other actions.
