Description
The present patent application be number of patent application be 201510523388.8, the applying date is August in 2015 24, entitled
The divisional application of the patent of invention of " high-temperature forging measuring apparatus ".
Technical field
The present invention relates to high-temperature forging measuring apparatus.
Background technology
Forging, refers generally to the heavy forging forged on 10MN hydraulic presses or 50kN forging hammers with steel ingot, and axial workpiece is general
At 5 tons or more, disk-like accessory is the core component for manufacturing Grand Equipments using free forging process generally at 2 tons or more.Big forging
When part forges, material and energy consumption are huge, and control forging's block dimension is of great importance for controlling quality, reducing cost.High temperature
The measurement difficult point of forging is its large scale, 1000 DEG C or so of high temperature, shines that strong, forging shop environment is extremely severe etc..
At present, forging and stamping factory both domestic and external, generally using contact type measurement.It is exactly that heavy forging leaves forging and stamping in the condition of high temperature
Machine is transferred to measurement station, operation clamp, gauge rod etc. and contacts directly high-temperature forging, naked eyes reading.At high operating temperatures,
So measurement, working condition has not been severe, but dangerous.And measurement data is very little, and measurement efficiency is low, low precision.It is aobvious
So, contact type measurement for high-temperature forging, and is not suitable for.
The non-contact measurement of high-temperature forging is development priority.Including laser beam projects method（Need a high-precision length
Rail guidance laser measurement heavy forging）, ccd image mensuration, laser scanning method.At present both after main development.Ccd image is examined
It surveys, contains much information, measurement efficiency is high, but easily disturbed, is limited by the CCD camera depth of field, and images match is difficult, it is necessary to scene
Calibration.Laser ranging, then higher to environmental requirement there are electronic system, the problems such as forging high temperature directly affects range accuracy.Have
The foreign commodities of a little open reports, technical indicator, environmental suitability are still not clear, the domestic report without using.And valency
Ge Taigao.It is published according to Nie Shaomin, Japanese plum Kui《Intermetallic composite coating hot-working》11 phases in 2008《The hot online ruler of heavy forging
Very little measuring study summary》, each enterprise uses manual method to measure substantially, and the heavy forging measurement in China is substantially at blank, enterprise
It is badly in need of, is ready to pay.Above-mentioned technical problem, it is seen that South China Science ＆ Engineering University's Li Zhelin doctoral thesis in 2013《Long axis based on CCD
The three-dimensional dimension of type high temp heavy forging surveys quantifier elimination》, Shanghai Communications University's Tian Zhisong doctoral thesis in 2010《Heavy forging is online
The key technology research of detecting system》, king nation of Dalian University of Technology doctoral thesis in 2011《The hot geometric parameter vision of forging
Measuring system research》.
Ranging plays an important roll in the industry.According to range measurement principle, trigonometry, impulse method, phase method can be divided into.Three
Horn cupping is that beam of laser is irradiated on object, and diffusing reflection laser in part is imaged by prism on photoelectric detection equipment.Trigonometry
Above there are many positional parameter requirements in application, it is very cumbersome and time-consuming in measuring apparatus calibration, if certain in system during actual measurement
Item parameter can not be obtained accurately, and measurement data will be caused to generate error.When measuring apparatus has small variations, each in system is joined
Number must all re-scale.See that the intelligence Sun Changku that admires writes perhaps,《3D reverse-engineerings》（China Measuring Press April the 1st in 2002
Version）p16.
He Baoxi is edited, and the Yellow River water conservancy publishing house in August, 2005 publishes it《Total station survey technology》Chapter 2, second save,
The range measurement principle of current total powerstation is described, mainly impulse method, ranging phase method, be required for the Department of Electronics of corresponding complexity
System.Impulse method ranging directly measures the time that the pulse that rangefinder is sent is tested distance back and forth.It is military according to Ye Xiaoming, Ling Mozhu
Chinese university press publishes it in March, 2004《The total powerstation errors of principles》P8, even if for timing clock frequency have it is atomic small
Error, also result in very big measurement error.For example clock frequency is 100MHz, even if having the frequency error of ± 1Hz, ranging
Error is also up to ± 1.5m.So impulse method measurement accuracy is low, it is mainly used for long-range low precision measure.Ranging phase method,
Principle be by measuring the phase place change that continuous modulated signal generates back and forth on testing distance come the indirect determination propagation time,
So as to acquire propagation distance.Ranging phase method is related to complicated control and computing, such as measurement ruler conversion and control, light path converting
Control, dim light automatically control, and survey phase rhythm（Timing control）, the conversion of phase distance, coarse-fine ruler is apart from Linking operation etc.（See leaf
Know bright, Ling Mozhu, publishing house of Wuhan University publishes it in March, 2004《The total powerstation errors of principles》p15）.The electronic system of measurement
It is complicated more than impulse method.Thus many problems can be caused.Ye Xiaoming, Ling Mozhu, publishing house of Wuhan University publish it in March, 2004
《The total powerstation errors of principles》The 3rd chapters of p42 are analyzed, for example, the same frequency photoelectricity in circuit harass signal caused by the cycle miss
Difference, inner quartz crystal oscillator are affected by temperature caused error.Li Guangyun, Li Zongchun are edited, Mapping Press 2011 1
Moon publication《Industrial measuring system principle and application》P134, caused by also referring to that actual range frequency and design frequency are inconsistent
Range error problem.
There are one problem is most important to range accuracy, no matter pulse ranging or phase ranging, range accuracy all takes
Certainly in the accurate measurement to the light velocity in air.And in actual measurement process, the light velocity is subject to the feelings such as atmospheric temperature, humidity, air pressure
Condition is influenced, it is necessary to measure these meteorologic parameters in advance, and carry out relevant atmospheric correction.It is edited according to Li Zeqiu, Wuhan science and engineering
University press publishes it in July, 2012《Total station survey technology》P22, the atmospheric correction of total powerstation also with the total powerstation used in
The wavelength of ranging light wave is related.
