Abstract
The utility model relates to the technical field of measurement and testing value transmission, and especially relates to a standard device used in three-dimensional non-contact measuring system calibration. Standard balls are connected to two ends of a measuring bar of the device. the utility model adopts the technical scheme; straight lines formed by the standard balls and ball supports are perpendicular to the measuring bar; during the measuring process, the standard balls can be completely measured by a three-dimensional non-contact measuring system; the surfaces of the standard balls are not reflective. The measuring bar is manufactured by using a material with low expansion coefficient, such that the influence on length change caused by thermal expansion and contraction is avoided. The device can adapt to various different testing requirements. With the device, three-dimensional non-contact measuring system measurement error and measurement uncertainty can be accurately detected.
Description
Technical field
The utility model patent relates to metrology and measurement transmission of quantity value technical field, especially relates to a kind of standard set-up for three-dimensional non-contact measurement system calibration.
Background technology:
At present, detection and the calibration for the 3 D non-contacting type measuring system still do not have reliable calibration criterion device, the production firm of 3 D non-contacting type measuring system all to use the standard set-up of oneself developing to calibrate.The standard ball of these standard set-ups can't be by complete measurement, and the surface reflection line can cause interference, and tested length is acted upon by temperature changes, thereby can't obtain measuring error and the uncertainty of measurement of three-dimensional non-contact measurement system accurately.
The utility model content
The 3 D non-contacting type measuring technique is an emerging measuring technique, various technology such as light harvesting, machinery, electronics, from the conventional metered dose technology and through accurate sensing process integration and the various modern high-tech means is integrated grows up.As emerging non-contact measuring technology, three-dimensional measurement is owing to its efficient height, and sweep limit is wide, more and more has been applied in measurement fast and the reverse-engineering.Follow a kind of so emerging measuring technique, it is particularly necessary that the accuracy of its magnitude tracing seems, calibration operation also need need to be resolved hurrily.Technical problem to be solved in the utility model provides the standard set-up that is used for three-dimensional non-contact measurement system calibration of defectives such as a kind of standard ball that overcomes prior art can't be disturbed by perfect measurement, surface reflection, environmental impact is big.The technical scheme that its technical matters that solves the utility model adopts is: a kind of standard set-up for three-dimensional non-contact measurement system calibration, its measurement rod two ends connect standard ball respectively.Technical problem to be solved in the utility model also can further be solved by following technical solution: measure the two ends of rod respectively through web member, ball support and connection standard ball; Standard ball is the black matt pottery.The black matt pottery that standard ball in the utility model is sold by Shenzhen hawk flag Industrial Co., Ltd. is made, and measures rod and is made by the little eastern beautiful 3k carbon fiber of expansion coefficient of the clear industrial corporation of monarch sale.The utility model is owing to adopt technique scheme, make standard ball and ball support and constitute straight line perpendicular to measuring rod, standard ball can be by the complete measurement of 3 D non-contacting type measuring system in measuring process, the standard ball surface is not reflective, measure rod and adopt the little material manufacturing of expansion coefficient, the influence of the length variations that causes of not expanded with heat and contract with cold can adapt to various test request, detects measuring error and the uncertainty of measurement of three-dimensional non-contact measurement system accurately.

Embodiment
With reference to Fig. 1-Fig. 7, the diameter of standard ball 1 is selected according to different detected space, the minimum that is about tested three-dimensional non-contact measurement system measurement space is measured 1/5 of length, the shape error of standard ball 1 is 0.2 μ m-1.0 μ m, there are 5 gluing connections of back shaft in a circular hole and the ball support 2 below of standard ball 1, ball supports the external thread 6 of 2 belows and is connected with internal thread 7 on the web member 4, the centre of sphere of measuring rod 3 is 200mm-2300mm apart from scope, and bolt 8 connects the internal thread of measuring on the rod 3 10 through the counterbore 9 on the web member 4 respectively.
Present embodiment is formed one group of measurement standard by 5 the utility model at least.The interior diverse location of measurement space scope that at first centre of sphere is placed on the 2000mm * 2000mm * 1500mm of 3 D non-contacting type measuring system apart from the different the utility model of length is measured.Form in one group of measurement standard at 5 the utility model, according to the standard centre of sphere of bee-line apart from need less than 3/10ths of the bee-line of measurement space, the standard centre of sphere of longest distance is apart from the three-dimensional catercorner length that needs 2/3rds measurement space at least, present embodiment adopts 200mm, 500mm, 1000mm, 1500mm, the centre of sphere distance of five dimensions length of 2000mm.The utility model is put 7 different locus to be measured, each position is measured respectively 3 times, obtain 35 groups of 105 (5 * 7 * 3=105) measured values, at last measured value and the standard value of the present utility model that obtains compared, can obtain the measuring error of 3 D non-contacting type measuring system, and evaluation is calibrated the uncertainty of measurement of 3 D non-contacting type measuring system.
