Description
One, technical field
The utility model relates to a kind of measurement that is used for the numerically-controlled machine linear axis, the step gage that bearing accuracy, repetitive positioning accuracy detect, specifically a kind of monoblock type horizontal-vertical double-purpose step gage is the standard utensil in a kind of length dimension Measuring and testing, belongs to national machinery standard manufacturing technology field.
Two, background technology
Be the material standard gauge that cushion block that the measurement gauge block made by stupalith and steel material are made is spliced and has the certain-length size now with step gage.The national standard " JB/T10977-2010 " of step gage issued in labourer hired by the month in 2010 7 letter radicals by which characters are arranged in traditional Chinese dictionaries.In September, 2010, the State Bureau of Quality Supervision issued step gage calibrating standard " JJF1258-2010 ".Should belong to a kind of new product.
1, the structure of step gage:
The structure of step gage is to be spliced successively by several 10mm pottery measurement gauge blocks and steel cushion block.
2, the accuracy class of step gage is divided into by " JB/T10977-2010 ":
0 grade, 1 grade, 2 grades, 0 grade the highest, and 2 grades minimum, sees Table 1.
3, the defective of existing step gage.
We find in detecting numerically-controlled machine, the 0 grade of step gage of a 500mm in existing the using, and dimensional stability is bad.Subsequently in the time more than a year to this step gage, thermal expansion amount under the natural temperature condition, carried out a large amount of detection research, find that existing step gage has two defectives: one is fault of construction, it is by 17 10mm ceramic gauge blocks, be spliced with 34 steel cushion blocks, each gauge block inevitably exists planarity, collimation, size, installation error factors, can not a rigid body after the splicing, when varying with temperature and the thermal expansion amount of standard gauge block very big difference is arranged, under different temperature, produce creep; Another defective is that pottery is different with the thermal expansion coefficient of steel material, and pottery is 9.5 * 10
-6℃, steel is 11.5 * 10
-6℃, two big defectives all influence the step gage dimensional accuracy, can produce very big measuring error in the use.
4, the test experience of step gage thermal expansion amount.
4.1, testing environment and condition.
The place is located at not to be had in refrigeration and the making-up shop of heating installation, and room temperature is a natural temperature, rises to 37 ℃ (Augusts) by 7 ℃ (January) in time and reduces to 7 ℃ (January).
4.2, installation and detection method.
The accuracy class of table 1 step gage
Installation method is with the half ceramic step gage of 0～500mm and the gauge block assembly of equidimension, is placed on the 00 grade of granite surface plate of 750 * 1000mm after strictness is cleaned, and the both sides of gauge block are provided with and prevent the device that collapses.Is that 0.1 μ m inductance amesdial reliably connects with the good support of rigidity with resolution, can carry out the gauge block assembly of step gage and equidimension contourly comparing and measuring.
During measurement gauge head is contacted with gauge block assembly upper surface, mix up the inductance amesdial zero-bit, again gauge head is pushed into the step gage measured surface, compare measurement.Each measurement number of times is carried out survey record greater than 10, when getting its mean value and measuring as this, and the difference in height of step gage and gauge block assembly.
5, the detection data of thermal expansion amount.
In the time more than a year, be raised to 37 ℃ of high temperature from 7 ℃ of workshop natural temperatures, when reducing to 7 ℃ again, done in a large number with machine testing, with these all temps numerical value of record down, pick out and have typical representative data, see Table 2.
The table 2 step gage temperature experimental data (μ m) that expands
By the variation of table 2 as can be known, the error of 500mm step gage when heating up is 8.3-(10.9)=19.2 (μ m), 3.0-(10.9)=13.9 (μ m) when cooling, and size is returned less than original position during cooling, differs 8.3-5.0=5.3 (μ m).
It is scaled every meter heat expansion amount difference with gauge block, then reach 19.2 * 2=38.4 μ m, the accuracy class requirement that far exceeds step gage, therefore under natural temperature, be difficult to guarantee, the accuracy of detection of numerically-controlled machine and length metering size, so big error can't guarantee the precision of step gage defined.
Three, utility model content
The purpose of this utility model just is to overcome existing step gage, it structurally not whole shape, the rigidity deficiency, each gauge block and cushion block inevitably exist planarity, collimation, size, installation error factors, add that the measurement gauge block is different with the cushion block thermal expansion coefficient, and after the splicing can not be a rigid body, when varying with temperature and the thermal expansion amount of standard gauge block very big difference is arranged, under different temperature, be easy to generate creep, only be adapted to 20 ℃ standard temperature, thus a kind of new technical scheme that proposes.
For achieving the above object, the utility model can be realized by following scheme:
A kind of monoblock type horizontal-vertical double-purpose step gage, it splices the step gage main body that the back is formed successively by single measurement gauge block, cushion block, be formed by connecting by holder, measuring gauge block and cushion block is one-piece construction, and the step gage main body of using at measurement size is concavo-convex notch one-piece construction; On the step gage main body, be provided with through hole; An end is provided with positioning seat on the step gage main body, is provided with attachment screw on positioning seat.
The concavo-convex notch that the step gage main body is provided with above is the rectangular strip toothing.
The advantage that the utility model is compared with prior art had is: the globality structure, good rigidly, the cost performance height, easy to assembly, can stand crouches installs and uses, thermal expansion coefficient is identical with tested lathe, and use error is little, the measuring accuracy height, identical with tested lathe thermal expansion coefficient, can overcome the measuring error that causes because of temperature variation fully, can adapt to the detection requirement under the normal temperature, improve the quality and the detection efficiency of product greatly.
