Positioner 20 slide on the first guide rail 11 and by the Hall electricity produced time below measuring probe 31
Pressure signal；And, controlling device (not shown), it includes controller, data collecting card and driving
Mechanism；Drive mechanism is connected to controller, is used for driving positioner 20 to slide along the first guide rail 11；
Wherein, the first guide rail 11 is provided with the first scale grating 12 being flush with it, and positioner 20 is provided with
Grating reading head (not shown), grating reading head reads location under the first scale grating 12 coordinates
The first displacement information that device 20 slides along the first guide rail 11 is also sent to controller；Controller is according to
One displacement information output triggers distance signal and triggers spacing to data collecting card, data collecting card every one
Read Hall voltage signal and convert thereof into magnetic density value and be sent to controller.
Originally stating in embodiment, the first guide rail 11 is the X-direction setting along platform 10, and magnetize Magnet
21 is five pieces of integrated little magnetic piece, and the centrage of the length direction of the Magnet 21 that magnetizes also is along X-direction.
Measuring probe 31 is Hall element, and certainty of measurement is 0.2mT.Because measuring probe 31 is relative to filling
The height of magnetic Magnet is different, and the measured value of magnetic density will have very large deviation, therefore, measuring probe
31 are in the position relative to the Magnet level altitude that magnetizes, this level altitude by actual experiments of measuring gained,
The present invention is not specifically limited.It is loaded with the positioner 20 of the Magnet 21 that magnetizes below measuring probe 31
Slide on first guide rail 11, when positioner 20 passes through below measuring probe 31, and the Magnet 21 that magnetizes
Centrage alignment measuring probe 31 time, measuring probe 31 gather produce Hall voltage signal, with this
Meanwhile, grating reading head reads the first real-time displacement letter that positioner 20 slides along the first guide rail 11
Ceasing and be sent to controller, controller triggers distance signal to data acquisition according to the first displacement signal output
Card, triggers distance signal and goes trigger data acquisition card to read current location for being spaced the distance triggering spacing
Hall voltage signal and convert thereof into magnetic density value and be sent to controller, it is achieved that lead along first
Magnetic flux at rail 11 line of travel (i.e. along the X-direction of platform 10), current measuring probe 31 height
The high-speed automated on-line measurement of metric density outline data, measures efficiency high.Number in embodiment of the present invention
It is 0.4 μm, sample frequency according to the accessible minimum spacing that triggers of capture card > 3000sps.It addition, will be fixed
The real time position that position device 20 slides is measured and is integrated with magnetic density measurement, passes through positioner
The real time position that 20 slide is measured output triggering distance signal and is read out with trigger data acquisition card；Each
The triggering of individual position, the magnetic density of the Magnet 21 that obtains magnetizing, in the data of three dimension profiles, is measured
Precision is high.As preferably, triggering spacing is 0.4 μm, while meeting high-speed automated on-line measurement,
Ensure the certainty of measurement of magnetic density.
In above-mentioned embodiment, as it is shown on figure 3, measurement apparatus 30 includes: probe fixing device 32,
It is for fixation measuring probe 31；First alignment pin 33, it is for connecting fixing for probe fixing device 32
Receive platform 10.Because measuring probe 31 is the most fragile, grazing is easily damaged, fixing device 32 is to survey
Amount probe 31 plays a good protection, and meanwhile, probe fixing device 32 is by the first location
Pin 33 is fixedly attached to platform 10, and measuring probe 31 is served good fixation so that measure
Probe 31 is in the position relative to the Magnet level altitude that magnetizes.The Magnet that magnetizes includes five blocks of integrated little magnetic
Block, is loaded with the positioner 20 of the Magnet 21 that magnetizes and slides and magnetize on the first guide rail 11 Magnet 21
Time below centrage alignment measuring probe 31, in order to ensure that measuring probe 31 gathers Hall voltage signal
Accuracy, when the overall dimensions of the Magnet 21 that magnetizes is about 30 × 8.5mm, the measurement of measuring probe 31
Induction region is set to 150 μ m 150 μm, has relatively large measured area, improves measurement
Accuracy rate.
The magnetize magnetic density size of Magnet 21 certain altitude of measuring probe 31 distance is to judge to magnetize magnetic
The important indicator whether ferrum 21 mass reaches a standard, therefore, magnetizes between Magnet 21 to measuring probe 31 distance
Relative altitude measure and adjustment seems particularly necessary.Another kind of specific embodiment party as the present invention

More than 3000sps, the certainty of measurement of measuring probe 31 is 0.2mT, the survey of magnetic density single measurement
The amount time can be less than equal to 2.5s.
This measuring method can realize GRR, and (Gauge Repeatability and Reproducibility measures
The repeatability of system and repdocutbility) < magnetic density of 20% is measured.
Preferred as one, measure before starting, further comprise the steps of: adjustment measuring probe 31 and the Magnet that magnetizes
Measuring probe 31 is also fixed by relative altitude between 21.
Because the magnetize magnetic density size of Magnet 21 certain altitude of measuring probe 31 distance is to judge
The important indicator whether Magnet 21 mass that magnetizes reaches a standard, therefore, magnetize Magnet to measuring probe 31 distance
Relative altitude between 21 measures and adjustment seems particularly necessary, specifically, can pass through platform 10
Upper laser displacement sensor 14, under the cooperation of the second guide rail, reads laser displacement sensor 14 and magnetizes
The first distance H vertical between Magnet 21 surface1It is sent to controller.Controller is according to the first distance H1With
The laser displacement sensor 14 measured in advance after mechanical erection and be saved in device program and measuring probe
The vertical drop second distance H of 312Calculate, output measuring probe 31 and Magnet 21 surface of magnetizing
Between relative altitude H, then relative altitude H=H1-H2.Finally, then by drive mechanism drive to measure and visit
31 slide to carry out the adjustment of relative altitude H along the second guide rail.
Preferred as one, in step 10, adjust positioner 20 be located at measuring probe 31 just under
Side, including step:
Motor is driven to drive the first guide rail 11 being loaded with positioner to slide to location dress along the 3rd guide rail 15
Put 20 to stop when being positioned at immediately below measuring probe 31；
Grating reading head reads the second displacement information that the first guide rail 11 slides along the 3rd guide rail 15 and sends
To controller.
Drive mechanism drives the first guide rail 11 of positioner 20 to slide to positioner along the 3rd guide rail 15
20 are positioned at immediately below measuring probe 31, the second displacement letter that the first guide rail 11 slides along the 3rd guide rail 15
Ceasing and be sent to controller, controller receives this second displacement information, it is judged that whether positioner 20 is positioned at
Below measuring probe 21.First guide rail 11 of positioner 20 slides into location dress along the 3rd guide rail 15
Putting 20 when being positioned at immediately below measuring probe 21, controller sends and stops signal to drive mechanism, stops sliding
OK.
