Abstract
The utility model provides a line scale verification device based on CCD video. The line scale verification device is composed of a guide rail and a detection machine head. The detection machine head is loaded with a CCD camera, a raster data processor and a computer. The detection machine head can transversely slide along the guide rail freely. The upper surface of the guide rail is provided with a stainless steel resistance-reducing shaft. The two ends of the guide rail are respectively provided with a fixation device. The line scale verification device based on CCD video has the advantages of being simple in structure, convenient to operate, high in precision, quick in efficiency and high in detection precision; and the line scale verification device can be widely applied to line scales, steel tapes, straight steel rulers, fiber tapes, measuring ropes and the like.
Description
Technical field
What the utility model designed is a kind of linear scale calibrating installation based on the CCD video.
Background technology
Linear scale is as a kind of instrument of measuring length the most commonly used at present, in people's life, be widely used, there is very strict standard in precision China for the linear scale scale, therefore also more and more higher for the requirement of linear scale calibrating installation, there are two defects at present traditional linear scale calibrating installation: the scale that 1) traditional linear scale contrasts linear scale to be measured and standard linear scale by the physics microscope is poor, judged the degree of accuracy of linear scale to be measured by the tester, physics microscopic precision is not high, and result is subject to the factor and individual subjective factor impact; 2) linear scale to be measured and standard linear scale are fixing when detecting easily is subjected to displacement built on the sand in observation process, affects observed result.
Summary of the invention
The utility model proposes a kind of linear scale calibrating installation based on the CCD video, its objective is to be intended to overcome in prior art and be subject to factor and individual subjective factor impact, the problems such as linear scale to be measured and standard linear scale easily are subjected to displacement when detecting in observation process, be conducive to improve the degree of accuracy of linear scale pick-up unit, there are the characteristics that equipment is succinct, easy to operate, precision is high, efficiency is fast simultaneously.
Technical solution of the present utility model: a kind of linear scale calibrating installation based on the CCD video is comprised of guide rail and detection head, be mounted with CCD camera, raster data processor, computing machine on described detection head, detecting head can laterally be free to slide on guide rail, guide rail upper surface is provided with stainless steel drag reduction axle, and the two ends of guide rail are respectively arranged with stationary installation; Stationary installation one end that described guide rail two ends arrange consists of geometrical clamp and stop means, and the other end consists of geometrical clamp, steel wire and counterweight.
Advantage of the present utility model: 1) adopt the CCD camera to replace traditional microscope physics eyepiece, improve the degree of accuracy detected; 2) at the guide rail two ends, stationary installation is set, linear scale in testing process can be subjected to displacement, guarantee that testing result is accurate.

Embodiment
Shown in Fig. 1, a kind of linear scale calibrating installation based on the CCD video is comprised of guide rail 1 and detection head 2, detect head 2 and can on guide rail 1, do free transverse shifting, the upper surface of guide rail 1 is provided with some stainless steel drag reduction axles 3, for slow down detect head 2 on guide rail 1 translational speed, the convenient operation person controls and detects head 2, detects on head 2 and is mounted with CCD camera 6, computing machine 7 and raster data processor 8, and CCD camera 6 is over against the upper surface of guide rail 1.During detection, first the end of standard linear scale is fixed on to the left side of guide rail 1 with geometrical clamp 9, geometrical clamp 9 connects steel wire 12, the end of steel wire 12 connects counterweight 11, effect by fixed pulley 10, utilize the gravity of counterweight 11 and the balancing controls 5 of right-hand member to determine that linear scale to be measured and standard linear scale are placed on zero-bit, again linear scale to be measured and standard strain line are fixed on to the right side of guide rail 1 with geometrical clamp 4, then the end of linear scale to be measured and standard linear scale is fixed on to the left side of guide rail 1 with geometrical clamp 9, the gravity of counterweight 11 is subject to identical tension force by linear scale to be measured and standard linear scale simultaneously simultaneously, require to join different counterweights according to the national verification rules, detect on head 2 and laterally move on guide rail 1, record the dial chart picture of linear scale to be measured and standard strain line by CCD camera 6, again image is inputted to raster data processor 8 and computing machine 7 analysis results.
Claims (2)
1. the linear scale calibrating installation based on the CCD video, by guide rail and detection head, formed, it is characterized in that on described detection head being mounted with CCD camera, raster data processor, computing machine, detecting head can laterally be free to slide on guide rail, guide rail upper surface is provided with stainless steel drag reduction axle, and the two ends of guide rail are respectively arranged with stationary installation.
2. a kind of linear scale calibrating installation based on the CCD video as claimed in claim 1, is characterized in that stationary installation one end that described guide rail two ends arrange consists of geometrical clamp and stop means, and the other end consists of geometrical clamp, steel wire and counterweight.
