Description

Roll eddy current automatic checkout equipment system state calibration equipment

Technical field

The utility model relates to a kind of automatic eddy current testing equipment, particularly roll checkout equipment system state calibration equipment.

Background technology

Weigh one of the non-destructive detecting device performance very important index, keep the relatively stable for a long time of detection sensitivity exactly.Checkout equipment when dispatching from the factory through professional's the detection sensitivity that adjustment reached in the relatively poor production scene of environmental baseline, be subject to electromagnetic interference (EMI), humidity and temperature, dust and greasy dirt and artificial factor, be difficult to accomplish remain unchanged in the long-term use afterwards, tend to because of certain a part of performance in the equipment makes a variation, and cause the stable performance sustain damage of total system.

In production practices, when the detection sensitivity of checkout equipment changes,, can't understand this situation immediately owing to there are not monitoring means.Only after a certain obvious consequence occurring, just begin it is thrown doubt upon, do not have means and can't carry out Analysis And Evaluation but suffer from.For the EDDY CURRENT equipment that disposes on the roll grinder, if descending appears in detection sensitivity, the defective that should grind off on the roll is not eliminated so, and quick-fried roller and roll breakage accident take place possibly, causes than large economy and loses; On the contrary, if rising appears in detection sensitivity, the defective that does not influence result of use so is required to grind off, and will increase abrasion, also can produce unnecessary economic loss.Therefore, the state of the necessary periodic check total system of checkout equipment keeps stable detection sensitivity.

One of existing method of calibration is to adopt to have the standard of the roll of certain natural flaw as verification, though the method can truly reflect the verification effect, needs long-time maintenance and maintenance as the standard roll, make its non-corrosive, impaired, do not produce new defective.As produce new defective, just can't accomplish to adopt same standard that checkout equipment is carried out verification, and, every standard roll will take certain place, kind according to grinding machine performance and tested roll, at least should there be three dissimilar standard rolls (cold roll, smooth roller and corresponding backing roll) could satisfy the need of verification, like this for existing production scene condition, can't be satisfactory.

Also having a kind of method is to adopt analog signal generator to produce a simulation wounding signal, be input in the checkout equipment, with the reaction to this simulation wounding signal, the initial value of noting when carrying out this verification for the first time with equipment compares, and just can know whether the state of system is normal again.Though this method is more convenient, but it is to the vitals in the checkout equipment---probe but can't carry out verification, and the stable operate as normal for whole detection system of probe performance is vital, so this method neither a good method.

Summary of the invention

The utility model is to satisfy the verification needs of roll eddy current checkout equipment, comprises control gear, and this control gear comprises the constant speed circuit board; Have housing, simulation sample roller, stepper motor, belt and the belt pulley of a side opening cavity in also comprising; Two side bodies are provided with bearing seat in this cavity; Said simulation sample roller two ends are arranged with bearing and are arranged in the bearing seat, and simulation sample roller one end links by an end of sheathed fixedly belt pulley on belt and the stepper motor, and stepper motor is connected with control gear; Stepper motor and control gear are arranged in the housing; Artificial indentation is carved with on simulation sample roller surface, can see the artificial indentation of simulation sample roller from cavity hatch.Control gear control step motor constant speed is rotated, and stepper motor drives simulation sample roller constant speed by belt, belt pulley and rotates, and implements verification for probe.Have advantages such as checking feature is good, convenience, compact conformation.

Embodiment

As shown in the figure, roll eddy current automatic checkout equipment system state calibration equipment comprises control gear 10, in housing 1, simulation sample roller 3, stepper motor 7, belt 6 and the belt pulley 8 of cavity 101 are arranged; These cavity 101 openings upwards (can be seen simulation sample roller 3 from opening part), and two side bodies 1 are provided with bearing seat 4 in the cavity 101; Simulation sample roller 3 two ends are arranged with bearing 5 and are arranged in the bearing seat 2, and simulation sample roller 3 one ends link by an end of sheathed fixedly belt pulley 6 on belt 5 and the stepper motor 7, and stepper motor 7 is connected with control gear 10; Stepper motor 7 and control gear 10 are arranged in the housing 1, and artificial indentation 301 is carved with on simulation sample roller 3 surfaces.Control gear 1 adopts the TC-02-E01 of Shanghai Minghua Checkout Facility Set Co., Ltd. constant speed circuit board.

Simulation sample roller 3 is diameter 50mm, is about 100mm, and simulation sample roller 3 surperficial electricity consumption spark method are carved an artificial indentation 301, and its length is 70mm, width 0.16mm, degree of depth 0.40mm.Be fixed in probe apparatus end (can see the simulation sample roller 3 that is carved with artificial indentation 301) by set screw 2 and register pin 4 whole calibration equipments from opening part, one side that register pin 4 is arranged is touched the shell of probe apparatus, register pin 4 inserts pilot hole, face that means for correcting makes progress is abutted against with the lower surface of probe apparatus, can not be gapped or loosening.Screw off socket protective lid on the probe apparatus (mainly be make socket does not make moist, dust stratification not) when grinding machine uses, the attaching plug on the means for correcting 11 is inserted sockets, start the correction program of defectoscope, and press the decline button of popping one's head in.Whole device enters correcting state, and instrument screen shows a plurality of equivalent values of crackle and shortcoming respectively.Whether work as EOP (end of program), probe contracts automatically to original position, and the equivalent value and the initial value of demonstration are made comparisons in corrected value deposit (can print when needing), normally can judge the state of total system.
