Abstract
The utility model relates to an exposed end optical fiber length detector of an optical-guided cable coupling piece, which belongs to the length measuring device, particularly a length measuring device for accurately measure tiny length (micron level) in a contact mode. The utility model comprises a percentage dial 1, a measuring rod 2 and a measuring head 3. The utility model is characterized in that the outside of the measuring rod 2 is in sleeve joint with a spacing measuring jacket 4; a fiducial surface at the bottom of the spacing measuring jacket 4 is provided with a measuring hole 5; in the measuring hole 5, the distance between the fiducial surface at the bottom of the measuring jacket 4 and the initial position of the measuring head 3 is equal to the standard length L< 0 > of a metal jacket 6 at the end part of the coupling piece being measured. The exposed end optical fiber length detector of an optical-guided cable coupling piece has the advantages of convenient operation and accurate measurement; due to the function of limiting dimension spacing, the utility model can quickly and conveniently measure out the tiny length of the exposed end optical fiber of the coupling piece of the optical-guided cable being measured, and can indicate whether the measured product exceeds the predetermined tolerance range or not. The utility model is especially suitable for the requirement of on-line detection in production departments.
Description
Technical field
Leaded light cable male part bared end fiber lengths detector belongs to length-measuring appliance, relates in particular to the length-measuring appliance that contact is accurately measured tiny length (micron order).
Background technology
The tiny length measuring method of existing leaded light cable male part bared end optical fiber has two kinds: a kind of is contact, and used survey instrument is common being seen vernier caliper.When operation, need inner-diameter measuring head, aim at the two ends of leaded light cable male part bared end optical fiber, read length from vernier caliper with vernier caliper.Because male part bared end length is generally at micron order, so bigger with vernier card measuring error, the internal diameter head of adding the vernier card is very tiny, sharp-pointed, and very easily the leaded light cable optical fiber to fragility causes the damage that can't repair.
Another kind is a non-contact measurement, and used tool is " universal tool-measuring microscope ".Its method of operating is: leaded light cable male part is fixed on the microscopical platform, and operating personnel regulate graticule by eyepiece, calculate the length of male part bared end optical fiber.This " universal tool-measuring microscope " be huge, the complex structure of equipment not only, and needs the professional to measure, and to operating personnel's technical requirement height, the measurement result individual error is also bigger, is difficult to satisfy the needs of online detection in the production run.
Summary of the invention
At the problem of above-mentioned existence, the utility model proposes a kind of leaded light cable male part bared end fiber lengths detector, it can carry out fast, accurately measure leaded light cable male part bared end fiber lengths easily and accurately.
Technical solution of the present utility model is: it comprises percentage dial plate 1, sounding rod 2 and measuring head 3, it is characterized in that: in the outside of sounding rod 2, be socketed with spacing measuring unit 4, have a measured hole 5 on the bottom reference field of described spacing measuring unit 4, in measured hole 5, the distance of the bottom reference field of measuring unit 4 and the initial position of measuring head 3 equals the standard length L of tested male part end metallic sheath 6
0
The measuring head 3 of dial gauge is a tack.Be provided with an outer ring that has a spacing sign 7 in the outer of percentage dial plate 1 circumference.The bonnet of percentage dial plate 1 is fixed on the base 8, is provided with over cap 9 at the upper surface of spacing measuring unit 4, and over cap 9 is connected as a single entity with base 8.
The leaded light cable male part bared end fiber lengths detector that adopts the utility model to make, simple in structure, easy and simple to handle, measure accurately.Owing to have the dimension limit limit function, can measure the tiny length of tested leaded light cable male part bared end optical fiber quickly and easily, and the indication test product margin tolerance of overshoot whether, be fit to very much the needs of the online detection of workshop.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is tested leaded light cable male part end construction synoptic diagram.
Embodiment
Consider that tested leaded light cable male part bared end optical fiber is tack, so need the spherical measuring head in the commercially available dial gauge is replaced as homemade hard stainless steel tack measuring head 3, spacing benchmark cover 4 is a stainless steel, size matches with sounding rod 2 external diameters, it is socketed in the outside of sounding rod 2, by about two screws 10 fixing.Have a measured hole 5 on the reference field of the bottom of sounding rod 2, in measured hole 5, the distance of the bottom reference field of measuring unit 4 and the initial position of measuring head 3 equals the standard length L of tested male part end metallic sheath 6
0Stainless steel outer ring that has spacing sign 7 of size processing according to percentage dial plate circumference is enclosed within percentage dial plate outer, and the reading of spacing sign is the permissible value of test product, is 0.1-0.4mm in the present embodiment.The bonnet of percentage dial plate 1 is fixed on the stainless steel base 8, is provided with stainless steel protection lid 9 at the upper surface of spacing measuring unit 4, with screw over cap 9 and base 8 is connected as a single entity.
During use, tested fiber guiding optical cable is inserted in the measured hole 5, make metal-coating 8 lower edges of male part concordant, at this moment because in measured hole 5, the distance of the bottom reference field of measuring unit 4 and the initial position of measuring head 3 equals the standard length L of tested male part end metallic sheath 6 with measurement aperture 5
0So the numeral that pointer shows on the percentage dial plate is exactly the length L of leaded light cable male part bared end optical fiber
1If pointer drops in the spacing sign 7 of percentage dial plate, then is certified products, otherwise is unacceptable product.
