Abstract
An automatic vortex detector system used for checking the vortex detector of roller is composed of controller, simulative sample roller with artificial scratch on its surface, step motor, leather belt and belt pulley. Its advantages are high check performance and compact structure.
Description
Technical field
The present invention relates to a kind of automatic eddy current testing 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 invention reside in the verification needs that satisfy EDDY CURRENT equipment, comprise control gear, 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.
