Description

Novel gear wheel detection equipment
Technical field
The present invention relates to gear wheel detection equipment.
Background technology
Gear is extremely important driving parts.The general gear by diameter more than 500mm, is called gear wheel.Wherein, diameter, at the gear of more than 3000mm, is called especially big gear.Gear wheel is the vital part of Large-Scale Equipment.The process equipment of gear wheel, makes great progress.Gear wheel measurement device, the measurement device of especially especially big gear, comparatively speaking, it appears very delayed, even lack necessary means.
The measurement of gear wheel, if adopting conventional measuring method, faced by first is exactly the structure of measurement device, volume increase.This results in huge problem.Measure with generating, it is necessary to high-precision long guideway, make extremely difficult.As for large-scale turntable when carrying super large gear, precise rotation, especially difficulty.Only heavy gear wheel finished product is positioned over the workbench of precision measurement equipment, is all huge challenge.Sum it up, the measurement of gear wheel, so far or a technical barrier.Refer to stone shine, Lin Hu, Lin Jiachun, Zhang Bai " gear wheel measure: present situation and trend ", " mechanical engineering journal " in May, 2013,49 volume 10 phases, p35.
Total powerstation is to apply extremely wide instrument of surveying and mapping.Total powerstation overall structure is divided into two large divisions: pedestal and alidade.The telescope of alidade, it is possible in horizontal plane and carry out 360 in vertical0Rotate, it is simple to sight target.Pedestal is used for the leveling of instrument and the connection of spider.The cooperative target of total powerstation is most commonly seen with prism.Wherein, prism is generally connected installation by pedestal with spider, and the conventional centering rod of single prism and support are installed.Referring to Li Zeqiu chief editor, publishing house of Wuhan University of Technology publishes it " total station survey technology " in July, 2012,2.1 joints, p14-p15.
Certain impact point can be found range and angle measurement by total powerstation at survey station point simultaneously, it is thus achieved that distance S, horizontal angle γ, tri-master datas of vertical angle α.Diastimeter
During measurement, at survey station point, total powerstation centering flattens, and at impact point, prism centering flattens.When target sighted by telescope, the horizontal limb degree of total powerstation provides horizontal angle and the vertical angle of the relative survey station point of impact point respectively with vertical circle.Li Zeqiu edits, and publishing house of Wuhan University of Technology publishes it " total station survey technology " in July, 2012,1.2 joints, and p7-p9 describes three kinds of scales such as coded circle, grating circle, dynamic scale.
Total powerstation is built-in infrared generator and receptor in telescope, it is possible to launch the infrared light coaxial with telescope optic axis.If there being non-prism to measure the total powerstation of function, the interior also built-in laser instrument of telescope, it is possible to launch the red color visible laser coaxial with telescope optic axis.By measuring light wave two-way time on testing distance, tested distance can be obtained.Seeing that He Baoxi edits, the Yellow River water conservancy publishing house publishes it " total station survey technology " p23, p27 in August, 2005.
He Baoxi edits, and the Yellow River water conservancy publishing house publishes its " total station survey technology " chapter 2 second section in August, 2005, describes the range measurement principle of current total powerstation, mainly impulse method, ranging phase method, is required for the complicated electronic system of correspondence.Impulse method is found range, and the pulse that directly mensuration diastimeter sends comes and goes the time of tested distance.According to Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publishes it " total powerstation errors of principles " p8 in March, 2004, even if the clock frequency for timing has atomic little error, also results in very big measurement error.Such as clock frequency is 100MHz, even if there being ± the frequency error of 1Hz, range error is also up to ± 1.5m.So impulse method certainty of measurement is low, it is mainly used in long-range low measure of precision.Ranging phase method, its principle is that the phase place change produced by measuring continuous print modulation signal to come and go on testing distance carrys out the indirect determination propagation time, thus trying to achieve propagation distance.Ranging phase method, relate to control and the computing of complexity, such as survey chi conversion and control, light path converting control, dim light automatically controls, survey phase rhythm (sequencing contro), phase place distance transform, coarse-fine chi distance Linking operation etc. (see Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publishes it " total powerstation errors of principles " p15 in March, 2004).The electronic system measured is complicated more than impulse method.Thus can cause a lot of problem.Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publishes it " the total powerstation errors of principles " p42 the 3rd chapter in March, 2004 and has analyzed, same frequency photoelectricity in such as circuit harasses the circular error that signal causes, the error that inner quartz crystal oscillator temperature influence causes.Li Guangyun, Li Zongchun edit, and Mapping Press publishes it " industrial measuring system principle and application " p134 in January, 2011, also mentions actual range frequency and the inconsistent range error problem caused of design frequency.
Having a problem that range accuracy is most important, no matter pulse ranging or phase ranging, its range accuracy both depends on the accurate measurement to the light velocity in air.And in actual measurement process, the light velocity is subject to the situation impacts such as atmospheric temperature, humidity, air pressure, it is necessary to measure these meteorologic parameters in advance, and carry out the atmospheric correction being correlated with.Editing according to Li Zeqiu, publishing house of Wuhan University of Technology publishes it " total station survey technology " p22 in July, 2012, the atmospheric correction of total powerstation also with this total powerstation used by the find range wavelength of light wave relevant.
