Abstract

The invention provides a fiber cutting apparatus blade fixation assembly. The assembly comprises a slide block, a knife rest and a blade, wherein the blade is fixed on the knife rest through a mounting shaft; the knife rest is fixedly connected with the front end surface of the slide block, a gap is arranged between the central portion of the knife rest and the slide block, the two ends of the mounting shaft are respectively supported on the knife rest and the slide block, at least one elastic pad is arranged between the side wall of the blade and the knife rest, one side of the blade abuts against the slide block, and the other side of the blade abuts against the elastic pad. When the slide block moves, the slide block drives the knife rest and the blade to perform relative movement, in the moving process when the blade is not in contact with a fiber, under the effect of the elastic pad, the blade is closely attached to the slide block, and the blade does not rotate relative to the mounting shaft; and when the blade is in contact with a fiber to be cut, the cutting edge of the blade cuts the fiber, and the blade rotates a certain angle along the center line of the mounting shaft to enable the cutting point position of the blade to be automatically changed, such that manual adjustment of the cutting position of the blade when the fiber is cut next time is avoided.

Description

Optical fiber cleaver blade fixation kit

Technical field

The present invention relates to a kind of optical fiber cleaver blade fixation kit.

Background technology

Optical fiber cleaver is a kind of specialized equipment cutting quartz glass optical fiber, optical fiber cleaver mainly comprises holder, slide block and blade, holder has chute, slide block is arranged in chute, slide block can along the Width to-and-fro movement of holder, blade is fixedly mounted on slide block, (blade is generally actionless to be distributed with 16 some positions on blade edge is even, 16 some position persons easy to use adjust the cutting position of blade cutting edge), the upper surface of holder is stretched out in the upper end of blade, during use, optical fiber is placed on holder upper surface, moving slider, band cutting blade cuts optical fiber, cutting optical fiber connector observation after hundreds of times of amplifications is still smooth, may be used for device package, cold joint, with electric discharge welding.

But current optical fiber cleaver is owing to fixing the position of blade, after long-time use, impact is had on cutting optical fibre cut-out section for avoiding blade abrasion, need to adjust blade, more the method for tool changing point position has two kinds: 1. when certain is stubbed to some position time, need manually adjustment, this kind of structure operation inconvenience; 2. can realize the structure automatically adjusting blade point position, but this apparatus structure is complicated, cost is relatively high.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of structure optical fiber cleaver blade fixation kit that is simple, adjustable blade point position automatically.

For solving the problems of the technologies described above, the invention provides a kind of optical fiber cleaver blade fixation kit, comprise slide block, knife rest and blade, blade is fixed on knife rest by installation shaft;

Knife rest is fixedly connected on slip front face, have gap in the middle part of knife rest and between slide block, installation shaft two ends are supported on knife rest and slide block respectively, are provided with at least one elastomeric pad between blade sidewall and knife rest, blade side is resisted against on slide block, and blade opposite side is resisted against on elastomeric pad.

After adopting such structure, moving slider, slide block band movable knife rack and blade relative motion, at blade not with under the effect of blade at elastomeric pad in the motion process of optical fiber contact, blade is close on slide block, and blade is mounted opposite axle and can not relatively rotates; Blade with when being with the optical fiber that cuts to come in contact, the cutting edge cutting optical fibre of blade, and blade turns an angle along the center line of installation shaft, and the some position of blade cuts is changed automatically, the cutting position of manual adjustments blade when avoiding next cutting optical fibre.

The material that the elastomeric pad of this optical fiber cleaver blade fixation kit adopts is rubber.

Accompanying drawing explanation

Fig. 1 is the structural representation of this optical fiber cleaver blade fixation kit.

Embodiment

As shown in Figure 1

This optical fiber cleaver blade 3 fixation kit comprises slide block 1, knife rest 4 and blade 3.

Slide block 1 front end face is fixedly connected with knife rest 4, gap 5 is had in the middle part of knife rest 4 and between slide block 1, installation shaft 6 two ends are supported on knife rest 4 and slide block 1 respectively, blade 3 is arranged in installation shaft 6, and blade 3 is in the gap 5 between knife rest 4 and slide block 1, be provided with at least one elastomeric pad 2 between blade 3 sidewall and knife rest 4, blade 3 side is against on the slider 1, blade 3 opposite side is resisted against on elastomeric pad 2, and blade 3 is mounted opposite axle 6 and can relatively rotates.

The material that described elastomeric pad 2 adopts is rubber.

Before using, be loaded on optical fiber cleaver by this optical fiber cleaver blade 3 fixation kit, slide block 1 can along the Width to-and-fro movement of optical fiber cleaver, and optical fiber to be cut is placed on optical fiber cleaver; During use, moving slider 1, slide block 1 is with movable knife rack 4 and blade 3 relative motion, and do not have with blade 3 in the motion process of optical fiber contact under the effect of elastomeric pad 2 at blade 3, blade 3 is close on the slider 1, and blade 3 is mounted opposite axle 6 and can not relatively rotates; Until blade 3 comes in contact with being with the optical fiber cut, the cutting edge cutting optical fibre of blade 3, and blade 3 turns an angle along the center line of installation shaft 6, the some position that blade 3 is cut changes automatically, the cutting position of manual adjustments blade 3 during optical fiber when avoiding cutting next time.

Above-described is only one embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, can also make some modification and improvement, and these also should be considered as belonging to protection scope of the present invention.

Claims

1. an optical fiber cleaver blade fixation kit, comprises slide block, knife rest and blade, and blade is fixed on knife rest by installation shaft, it is characterized by:

2. optical fiber cleaver blade fixation kit according to claim 1, is characterized in that:
