Description
Technical field
The present invention relates to a kind of insulated wire cores quality detection apparatus, be specially a kind of tester for yellow-green ratio of yellow green line core.
Background technology
According to state quality standard requirement, qualified insulation cable, yellow and the green ratio of its yellowish green core will reach 30-70% respectively.When carrying out the yellowish green core goniometry of insulation cable at present, usually adopt two kinds of methods, one is directly measure with projector, or forms image with projector, and recycling special measurement software processes image data, and completes surveying work to workpiece; Two is with paper tape, encloses around wire surface bag one, carries out mark in yellow and green portion, then by measuring girth, calculate yellowish green length ratio draw both ratio.All there is certain drawback in two kinds of methods: the former operation easier is larger; The latter cannot measure fine rule core.And both measuring error are large, difficulty realizes Measurement accuracy.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to operate, the analyzer of Accurate Determining yellowish green core yellow green ratio can be realized.
The object of the invention is to adopt following technical proposals to realize: tester for yellow-green ratio of yellow green line core, it comprises index dial, index dial center is provided with at least one pointer, is provided with transparent plate above index dial and pointer, and index dial center and transparent plate center are on same vertical curve.Measured piece is placed in transparent plate center, by adjustment pointer, measures the angle angle that yellowish green core two point of interface is formed to the center of circle.Pull out the extended line of yellowish green two point of interfaces to the center of circle, measure two extended lines formed angle angle, angle be greater than 108 degree be monochrome more than 30%, being less than 252 degree is that monochrome is less than 70%.
Described index dial circumferential edge is provided with draw-in groove, is provided with circumference protective shield below described transparent plate, and protective shield lower limb snaps in index dial draw-in groove and can rotate in draw-in groove.Protective shield plays dust-proof effect of Denging, protection index dial and pointer; Transparent plate rotates and measured piece can be made to find more suitably locate, and realizes more precise angle and measures.
Also magnifier is provided with above described transparent plate.When measuring fine rule core, more Measurement accuracy can be realized.
Also transparent pressing plate is provided with above described transparent plate.Arranging of transparent pressing plate ensures that measured piece stable extrusion is between transparent plate and transparent pressing plate, is convenient to position and fixes; On the other hand, even if measured piece surfacing is irregular, under the extruding of transparent plate and transparent pressing plate, smooth tested surface can be obtained, reduce operation easier when measuring.
Also magnifier is provided with above described transparent pressing plate.When measuring fine rule core, more Measurement accuracy can be realized.
Described index dial center is equipped with axle sleeve, and be provided with rotating shaft in axle sleeve, rotating shaft is connected with pointer, and rotating shaft is rotated and then driven indicators turn in axle sleeve.
Described pointer is 1.A certain scale mark on setting index dial is 0 degree of line, is rotated by transparent plate, 0 degree of line is aimed in one of them yellowish green boundary line of measured piece, by 1 another yellowish green boundary line of pointer rotary alignment measured piece, reads index dial angle, realize goniometry.
Described pointer is 2; 2 rotating shafts are installed, respectively at wherein 1 pointer is connected in described axle sleeve.Rotate 2 pointers respectively, aim at two yellowish green boundary lines of measured piece respectively, read index dial angle, realize goniometry.
Beneficial effect of the present invention is according to known to describing of such scheme: structure is simple, cost is low; Easy and simple to handle, reduce work difficulty during measurement; Realize Accurate Determining yellowish green core yellow green ratio.
