Abstract
The invention discloses a wire flex-resistance online detection method. According to the method when used in wire flex-resistance detection, a wire folded part is X-rayed by the use of an X-ray emitter, a ray receiver displays a perspective result, and the perspective result is utilized to determine whether the wire is cracked; and when the wire is cracked, the wire flex-resistance is determined based on the folding times for generating the cracking. By the adoption of the method provided by the invention, whether the wire is cracked can be directly observed. The detection result is reliable and has high accuracy. The method provided by the invention is used in detection of wire flex-resistance.
Description
Technical field
The present invention relates to a kind of detection method of electric wire, particularly relate to a kind of online test method of electric wire stiffness.
Technical background
Electric wire is a kind of product commonly used in daily life and the production, and the capability and performance of electric wire is extremely important, and wherein the stiffness of electric wire also is one of very important performance.In a lot of fields, the stiffness of electric wire has often determined the quality of other products, as: the requirement of the connection wire pair stiffness that arrangements for automotive doors is used is very high, because car door is wanted frequent opening and closing, if the anti-crawl agentdefiection poor performance will make car door break down, can't use as power windows etc.Detection about electric wire has a lot of methods, in number of patent application 201110096196.5 denominations of invention " a kind of electric wire pick-up unit and detection method " of 2011.11.02 bulletin a kind of electric wire pick-up unit is disclosed as Patent Office of the People's Republic of China, by using image read-out to obtain the status information of electric wire in real time, and send to server and handle, realize understanding in real time the state of electric wire, realize power transmission line early warning robotization, improve the efficient and the quality that detect.But how this invention does not detect the method for the stiffness of electric wire.Therefore, be badly in need of the online test method of a kind of accuracy height, electric wire stiffness that detection efficiency is good now.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, the online test method of a kind of accuracy height, electric wire stiffness that detection efficiency is good is provided.
For this reason, the invention provides a kind of online test method of electric wire stiffness, described method is when electric wire being carried out the stiffness detection, utilize ray emitter that the dogleg section of electric wire is had an X-rayed, the ray receptacle will be had an X-rayed the result and show, and the result judges whether electric wire produces fracture from perspective; When producing fracture, the stiffness of how much judging electric wire of the bending times of carrying out when rupturing from producing.Generally speaking, the ray of described ray emitter emission is X ray.The stiffness of electric wire is very important performance, under many circumstances, the quality of stiffness is related to the quality of product, as the car door of automobile owing to often close or open, if the anti-crawl agentdefiection poor performance of electric wire will make the partial function of car door lose specially, can't open an account or close as power windows.Because the crust of electric wire is opaque, whether ruptures so can't directly observe the conductive filament of the inside when carrying out the folding test of stiffness, but adopt this detection method of the present invention can judge directly whether the conductive filament of the inside ruptures.
In the online test method of another kind of electric wire stiffness provided by the invention, described ray receptacle links to each other with image display, and whether the conductive filament of directly observing electric wire inside by image display ruptures.Whether the receiving method of ray has a variety of, as utilize film to carry out sensitization and also can observe the conductive filament of the inside and rupture, and this accepting method has the cheap advantage of equipment, but need carry out after the photographic fixing just knowledge of result to film.Show that then can directly obtain the result, speed is fast, can reach the effect of carrying out online viewing test result if adopt image display to carry out image.
In the online test method of another kind of electric wire stiffness provided by the invention, described ray generator and ray receptacle and detected electric wire wherein are installed in the ray protective cover.In protective cover, can protect testing staff's health safety effectively.Certainly, also described electric wire stiffness pick-up unit and ray emitter and receptacle all can be installed in the ray protective cover.For the ease of direct viewing test state, the material of described ray protective cover is lead glass.Lead glass also has transparent function except having the defencive function to the testing staff, the state the when testing staff can observe directly test.
In the online test method of another kind of electric wire stiffness provided by the invention, described ray emitter and receptacle can carry out 360 ° of rotations around detected electric wire.The crust the inside of electric wire has many conductive filaments sometimes, and the crack conditions by rotation can be observed conductive filament exactly reduces the dead angle, visual angle.Equally, described ray emitter and receptacle can carry out left and right movement along detected electric wire, because electric wire has certain length when detecting, can judge the position of fracture exactly by left and right movement.Certainly, described ray emitter and receptacle can carry out 360 ° of rotations around detected electric wire, simultaneously can also left and right movement, can enlarge the scope of detection like this.
The online test method of a kind of electric wire stiffness provided by the invention is compared with existing method and is had the following advantages:
1. accuracy height: whether the conductive filament that the present invention can observe directly the electric wire the inside of online detection ruptures the accuracy height.
2. the high cycle of detection efficiency is short: can judge testing result rapidly by image display, efficient height, cycle weak point.
Embodiments of the invention below by accompanying drawing is described can more be expressly understood design of the present invention, method.
Description of drawings
Accompanying drawing 1 is the principle schematic of an embodiment of the online test method of a kind of electric wire stiffness provided by the invention.
Embodiment
With reference to accompanying drawing 1, accompanying drawing 1 has been described the principle schematic of an embodiment of the online test method of a kind of electric wire stiffness provided by the invention: the two ends of detected electric wire 3 are respectively by on left wheel 1 and right wheel 2, left wheel 2 and right wheel 3 can constantly carry out synchronous clockwise and be rotated counterclockwise.Whenever rotate a certain angle, just constantly by bending, simultaneously the number of times of bending is counted (not drawing among the counter figure) around top electric wire 3.The ray 5 that X ray transmitter 3 sends penetrates electric wire 3, after ray receptacle 6 receives ray 5, by display 7 ray of accepting 5 is shown, whether the conductive filament (not drawing among the figure) in the electric wire 3 that shows in the observation display 7 fracture has taken place, if find that fracture has taken place conductive filament, stop the rotation of left wheel 1 and right wheel 2, write down the number of times of rotation, thereby determine the anti-crawl agentdefiection performance of electric wire 3.
Above described embodiment be that the present invention will be described, be not that the present invention is limited.Design, method and scope that the present invention is claimed all are documented in claims of the present invention.
