Description
Technical field
The utility model relates to a kind of pick-up unit, and specifically the metal magnetic memory multi-channel testing device can carry out the detection of precise and high efficiency to cylinder class part peace plate parts.
Background technology
Adopt lossless detection method that boiler, pressure vessel, pressure pipeline, railway, bridge and some other special equipments are carried out quality discrimination, the accident that prevents takes place, and has great society and economic benefit.At present, the Non-Destructive Testing of the said equipment is mainly adopted conventional methods such as ultrasonic, magnetic, ray, eddy current and infiltration, it is ripe that these methods have become, but still come with some shortcomings: can not find and predict the position that defective will take place; Generally need detected object to quit work; Pre-service such as decoating, polishing will be carried out in the checked object surface; The accuracy of testing result is subjected to factor affecting such as workpiece shape, structure and Personnel Skill Levels; On-the-spot detection working condition is poor, and the intensity height is difficult to avoid omission.The metal magnetic memory detection method is a kind ofly can determine on the detected object with stress and distortion concentration zones to be unique lossless detection method of the hazardous location of sign with pin-point accuracy, can be by the early diagnosis security of valuator device comparatively exactly.This technology has remedied the deficiency of traditional lossless detection method, has following outstanding features: the detection of equipment exposed parts be need not equipment quit work; Need not the detected object surface carried out pre-service such as decoating, polishing; Characteristic signal is obvious, removes human factor, accuracy height as a result; Can realize fast detecting and detect robotization, can carry out 100% fast checking, raise the efficiency, avoid omission equipment; Need not special magnetizing assembly, the checkout equipment volume is little, in light weight, cost is low thereby make; Can also improve working conditions simultaneously, reduce labour intensity.The size of the probe of metal magnetic memory pick-up unit is very little usually, so that realize spot measurement.Domestic metal magnetic memory pick-up unit all is to adopt single sonde configuration at present, and this workload when the larger-size cylinder class part peace of detection plate parts is very huge, can't embody the high efficiency of magnetic memory detecting method.Probe is generally hand-held during detection, and angle and lift off was more between probe and the measurand can be subjected to certain artificial factor, causes the inaccurate of measurement result.Designed magnetic memory multi-channel testing device for this reason, can carry out the detection of precise and high efficiency cylinder class peace plate parts.
Summary of the invention
The purpose of this utility model is the magnetic memory multi-channel testing device for realizing the detection that the peaceful plate parts of cylinder class carries out precise and high efficiency is designed.
The technical scheme that its technical matters that solves the utility model adopts is: this pick-up unit mainly is made up of flaw detection dolly, fixed mount and the magnetic memory detecting sensor of popping one's head in probe more.The whole non-magnet material that uses titanium alloy and aldary of this pick-up unit is to eliminate the influence of stray magnetic field.Many probe fixed mounts are by being bolted on the four-wheel flaw detection dolly, and magnetic memory sensor probe is fixed on many probe fixed mounts, visits frame height nut by regulating, and can adjust the lift off was more between probe and the measurand.Many probe fixed mounts are designed to dismountable, can be according to different situations layout circle arc fixed mount and linear pattern fixed mount to adapt to the requirement of different detected objects such as cylinder class and flat-type.Detecting a flaw is connected with photoelectric encoder by shaft coupling on the little back wheels of vehicle, can export pulse triggering signal and supply with the subsequent sampling circuit and use.
The beneficial effects of the utility model are: can carry out the detection of 5 passages simultaneously to cylinder class and flat-type measurand, improve detection efficiency greatly, reduce labour intensity.Guaranteed that in testing process angle and lift off was more between probe and the measurand are invariable, improved the accuracy that detects.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further:
Fig. 1 is many probe magnetic memory detection device overall patterns.
Fig. 2 is a cylinder class piece test synoptic diagram.
Fig. 3 is a flat-type piece test synoptic diagram.
Among the figure: 1. many probe fixed mounts, 2. probe height nut, 3. probe bracket, 4. pop one's head in, 5. limit sliding chutes, 6. the probe set nut is 7. visited frame height nut, 8. adjustment seat, 9. adjusting bolt, 10. flaw detection dolly, 11. photoelectric encoders, the fixed mount 12. circular arc is popped one's head in more, the 13. linears fixed mount of popping one's head in more
Embodiment
5 probes are fixed on many probe fixed mounts 1 simultaneously, can carry out the detection of 5 passages simultaneously measurand.Many probe fixed mounts 1 according to different situations can layout circle arc fixed mount 12 with linear pattern fixed mount 13 to adapt to the requirement of different detected objects such as cylinder class and flat-type.Probe is fixed on many probe fixed mounts (1), make it keep vertical with the measurand surface, can regulate simultaneously and visit frame height nut 7, realization is similar to the thread depth regulatory function of milscale principle, adjust the lift off was more between probe 4 and the measurand, can read lift off was more, realize the parametrization of lift-off value, guarantee that probe apparatus can adapt to the caliber of all size, and angle and lift off was more between probe and the measurand are remained unchanged in whole testing process.
Embodiment one: the fixed mount 1 of popping one's head in more, and probe bracket 3, limit sliding chutes 5 and adjusting bolt 9 are fixed together, and link together by adjustment seat 8 and flaw detection dolly 10.Can adjust probe with respect to the lift off was more between the measurand by regulating probe height nut 2.Regulate and visit frame height nut 7, limit sliding chutes 5 is slided up and down with respect to adjustment seat 8, thereby drive many probe fixed mounts 1, probe bracket 3 and probe 4 grades move up and down together.When adjusting to the appropriate location, rotating detector set nut 6 can be locked together regulating bolt 9 and adjustment seat 8.
Detecting a flaw is connected with photoelectric encoder 11 by shaft coupling on the little back wheels of vehicle, and when flaw detection dolly during at the measurand apparent motion, photoelectric encoder 11 can be exported pulse triggering signal and supply with the subsequent sampling circuit and use.
Wherein, the fixed mount 1 of popping one's head in has two kinds of forms more: circular arc fixed mount 12 and the linear fixed mount 13 of popping one's head in of popping one's head in more more, and according to the difference of measurand, can select suitable many probes fixed mount to be connected with flaw detection dolly 10.
