The beneficial effects of the utility model are that, the error is little, and measurement of efficiency is high.
Description
Technical field
This utility model relates to linear scale fields of measurement, particularly a kind of linear scale measuring instrument.
Background technology
Linear scale measurement is one procedure particularly important in linear scale production process, and it directly determines the precision of linear scale, it is ensured that measurement effect.Traditional linear scale measures the precision being all to use third metal lines meter ruler to determine new linear scale by the way of magnifier comparison, but this mode to contact measured linear scale, the position error of the most measured linear scale is bigger, and by the way of magnifier contrasts, judging that precision is relatively low, measurement effect is the best.
Utility model content
The purpose of this utility model is to solve the problems referred to above, devises a kind of linear scale measuring instrument.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of linear scale measuring instrument, including platform, measured straight steel ruler and grating displacement sensor it is fixed with on platform, grating displacement sensor is parallel to each other with measured straight steel ruler, the side of platform is provided with traverse measurement observation unit, and described traverse measurement observation unit is that the auxiliary support frame being provided with accurate sealed bead bearing guide rail moved along platform side by CCD camera camera lens and the light-emitting diode display of CCD camera camera lens electric connection and driving CCD camera camera lens and light-emitting diode display collectively forms.
Described light-emitting diode display be by cabinet, be arranged on cabinet show the image display panel of CCD camera lens shooting picture, be arranged on cabinet show grating displacement sensor reading of standard numerical value display screen, print papery strip LPT and control button collectively form.
The a length of m of described grating displacement sensor.
Described platform is marble platform.
Utilize the linear scale measuring instrument that the technical solution of the utility model makes, owing to instrument have employed non-contact measurement mode, thus avoid the position error that the unreliability positioning tested linear scale is brought；Linear scale measuring instrument global design is rational in infrastructure, easy and simple to handle, can realize more complete calibration operation in conjunction with computer application.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is specifically described, if Fig. 1 is the structural representation of linear scale measuring instrument described in the utility model, as shown in the figure, a kind of linear scale measuring instrument, including platform 1, measured straight steel ruler 2 and grating displacement sensor 3 it is fixed with on platform, grating displacement sensor is parallel to each other with measured straight steel ruler, the side of platform is provided with traverse measurement observation unit, described traverse measurement observation unit is by CCD camera camera lens 4, the light-emitting diode display 5 being electrically connected with CCD camera camera lens and driving CCD camera camera lens and light-emitting diode display collectively form along the auxiliary support frame 6 being provided with accurate sealed bead bearing guide rail that platform side moves.Wherein, described light-emitting diode display be by cabinet 11, be arranged on cabinet show the image display panel 7 of CCD camera lens shooting picture, be arranged on cabinet show grating displacement sensor reading of standard numerical value display screen 8, print papery strip LPT 9 and control button 10 collectively form；The a length of 1m of described grating displacement sensor 3；Described platform 1 is marble platform.Traverse measurement observation unit moves by being provided with the side surface along platform that drives of the auxiliary support frame of accurate sealed bead bearing guide rail, the scale of the measured straight steel ruler of its internal red graticule instruction of CCD camera shot record is also shown on image display panel, grating displacement sensor then records distance that traverse measurement observation unit moves and shows on numerical value display screen by this distance values, the shift value measured in scale that staff is specified by image display panel internal standard line and grating displacement sensor is compared, thus measure the measurement error of straight steel ruler, reach to measure the effect of its precision.
In the technical program, linear scale measuring instrument uses high accuracy long grating displacement sensor as the working standard of instrument.Use industrial camera to combine LED display as measuring observing unit simultaneously.This instrument directly substitutes third metal lines meter ruler and builds mark project equipment as linear scale class.The linear scales such as less than one meter straight steel ruler can directly be measured by linear scale measuring instrument, more than one meter straight steel ruler can be done method of fractionation and measure.It is (0 5000) mm that its method of fractionation measures scope.Linear scale measuring instrument uses brand new technical to instead of traditional third metal lines meter ruler working method.It complies fully with JJG1-1999 " straight steel ruler " national metrological verification regulations requirement.Instrument uses one meter of grating displacement sensor to provide the output of reliable digital information as working cell.Use the combination of industrial camera and LED display, not only than traditional magnifier estimate read mode and improve accuracy of measurement, achieve the quick of work and comfortableness by the data output that mini-printer is the most errorless simultaneously.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; some variations that some of which part may be made by those skilled in the art all embody principle of the present utility model, within belonging to protection domain of the present utility model.
