Abstract
The invention discloses a cable insulated layer thickness detection method. The cable insulated layer is cut off firstly, two ends of the insulated layer are fixed respectively, two infrared distance measuring instruments are placed relative to two end surfaces of the insulated layer respectively, the distance between the two infrared distance measuring instruments is a fixed value L, the two infrared distance measuring instruments are started, the distance value of one infrared distance measuring instrument is S1, the distance value of the other infrared distance measuring instruments is S2, and the thickness of the insulated layer is D=L-S1-S2. By adopting the infrared distance measuring instruments for measurement, and the measured value is accurate and high in precision; thickness detection can be carried out on multiple positions of the insulated layer, the measured values can be compared, when the measured values are in a set value range, the product is qualified, and if a certain measured value exceeds the set range value, the cable thickness is not qualified.
Description
Technical field
The present invention relates to cable manufacture field, specifically a kind of detection method of cable insulation layer thickness.
Background technology
Cable mainly by inner wire, be arranged at the insulation course outside inner wire and the insulation course be wrapped in outside insulation course forms, the thickness of insulation course determines the electrical specifications of cable.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of detection method of cable insulation layer thickness, and adopt infrared distance measuring principle to carry out multimetering, measured value is accurate, and precision is high.
Technical scheme of the present invention is:
A kind of detection method of cable insulation layer thickness, first the insulation course of cable is cut open, then the two ends of insulation course are fixed respectively, finally the both ends of the surface of two infrared ambulators difference opposing insulation layers are placed, the distance of two infrared ambulators is definite value L, then starts two infrared ambulators, and the distance value of an infrared ambulator measurement is S1, the distance value that another infrared ambulator is measured is S2, the thickness D=L-S1-S2 of insulation course.
The two ends of described cable insulation press from both sides as between two plate holders respectively, and namely the both ends of the surface at insulation course both ends are fitted with corresponding plate holder respectively and clamped.
The height of two described infrared ambulators is consistent, and the line of two infrared ambulators and insulation course are vertical relation.
Advantage of the present invention:
The present invention adopts infrared ambulator to measure, and measure numerical value accurate, precision is high; The present invention can carry out thickness measure to multiple positions of insulation course, and measured value contrasts, and when measured value is in the scope of setting value, namely product is qualified, if a certain measured value exceedes setting range value, i.e. and cable insulation unqualified thickness lattice.
