The utility model content
The utility model provides a kind of integrated guide tracked electronic mechanical rebound apparatus, thus to solve sensor fixed grid and moving grid can not guarantee enough three-dimensional accuracies, easily take place shake up and down and about distortion cause that the reisilometer cumulative errors are higher, the problem of unstable properties.
The technical scheme of the integrated guide tracked electronic mechanical rebound apparatus of the utility model: have the shell that a long tubular has scale, shell is built-in with an elastic stem that has weight, concatenation pointer on the elastic stem, with the corresponding shell of pointer on have scale slot, the pointer other end connects slide block, slide block is through on the slide bar, fixedly connected sensor moving grid above the slide block, the sensor moving grid is corresponding with enclosure fixed sensing fixed grid, gapped between sensor fixed grid and the moving grid, and be electrically connected by lead with electronic console, it is characterized in that: the sensor moving grid places in the integrated guide rail, integrated guide rail is connected as a single entity by the bottom connecting plate, have the slider guide cylindrical void in the middle of the connecting plate of bottom, integrated guide rail both sides opposed inside has gathering sill, and sensor moving grid dual-side inserts in the gathering sill of both sides, and the sensor fixed grid is fixed on above the integrated guide rail.
Above the above-mentioned integrated guide rail fixed grid platform is arranged.
Above-mentioned pointer is wing shape sheet metal or non-metal plate.
Connect the sensor moving grid by screw or adhesive securement above the above-mentioned slide block.
The sensor fixed grid by screw or adhesive securement on integrated guide rail.
The sensor is magnetic grid displacement transducer, synchronous inductor displacement transducer, area-changing capacitance displacement transducer or photopotentiometer formula displacement transducer.
Principle of work: when the weight of integrated guide tracked electronic mechanical rebound apparatus drives slide block movement, place the moving grid of the displacement transducer of slider top, and place the wing type pointer of slide block side, simultaneously with the slide block associated movement, when slide block moves a distance, then pointer also moves a distance, can see through scale slot and its mechanical indicating value of transparent scale direct-reading; Moving grid then demonstrates corresponding resilience indicating value by electronic circuit on the fixed grid and microprocessor with respect to the distance that fixed grid moved on electronic console.The displacement induced potential is sent into microprocessor and by the null value algorithm displacement is calculated through the signal transformation of A/D analog to digital, is scaled the special-purpose indicating value of reisilometer at last, through the conversion of D/A digital-analog signal, demonstrates on electronic console again.
Beneficial effect: the integrated guide rail of the utility model is that two guide rails with sensor moving grid both sides are connected to a global facility by the bottom connecting plate; In integrated guide rail, have and aim at two accurate gathering sills that the sensor moving grid moves in high speed, long distance; On the connecting plate of the bottom of integrated guide rail, have the slider guide cylindrical void; Above two gathering sills of integrated guide rail, form two fixed grid platforms, to install and fix the usefulness of sensor fixed grid through precise finiss.The sensor moving grid that above-mentioned technological improvement has been eliminated the slide block of delivery sensor moving grid and made high-speed mobile at a high speed and produce when relatively moving about moment, about shake and rock, two of integrated guide rail guiding under spacing, the guide effect of poor and slider guide cylindrical voids, guaranteed that sensor moving grid, fixed grid dynamically down, still have stable, accurate gap and three-dimensional relative accuracy.It is higher that the utility model has solved the reisilometer cumulative errors, and the problem of unstable properties guarantees that measurement data is accurate, stable.
The utility model combines the advantage of mechanical type reisilometer and electronic digit reisilometer, adopt contactless displacement sensor to be electrically connected with electronic console, do not destroy, do not influence yet mechanics, the elastic potential energy performance of former mechanical reisilometer, improved intelligent degree.Adopt wing shape pointer to be connected between slide block and the elastic stem, and be equipped with guide rail, improved measuring accuracy, speed and accuracy, prolonged serviceable life in the moving grid both sides.Measuring accuracy and resolution are micron (μ m) level, for only requiring millimetre-sized reisilometer indicating accuracy, are to satisfy fully.This reisilometer can carry out calibration calibrating, metering.
