Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of plane wave momentum calibrating installation, it comprises benchmark flat board 1, on benchmark flat board 1, be fixed with micrometer gauge 2, the lower end of described micrometer gauge 2 is provided with check-out console 3, described check-out console 3 is connected with benchmark dull and stereotyped 1 by spring 4, is fixed with leg 5-1 on the bottom surface of described check-out console 3 No. one, is fixed with leg 5-2 on the bottom surface of benchmark flat board 1 No. two.
In the such scheme, a preferred leg 5-1 has one, and No. two leg 5-2 have three and be triangularly arranged.
During work, the bottom surface of at first controlling all legs is in same plane substantially, that is to say, four legs of check-out console and benchmark flat board are in same plane.When detecting, calibrating installation kept flat place certain part of detected working face, three legs of benchmark flat board can allocate face at 3, this plane is as a reference field, and a leg of check-out console, as the zero point of reference of this reference field,, make four legs be equivalent to same plane with the micrometer gauge zeroing.When promoting calibrating installation to each part plan of working face, as long as the benchmark flat board is indeformable, then reference field does not change, and the leg of check-out console can pass to micrometer gauge by check-out console with the alternate position spike of part plan, and micrometer gauge just indicates the position extent, as certain local dent, check-out console is subjected to self-gravity action, the leg of check-out console reduces check-out console, and check-out console just produces displacement downwards, and then just to indicate alternate position spike be negative value to micrometer gauge; If certain local crowning, the circular leg jack-up check-out console of check-out console, check-out console just upwards produce displacement, then micrometer gauge just indicate alternate position spike on the occasion of.
In the such scheme, a preferred leg 5-1 and No. two leg 5-2 are circular leg, and circular leg bottom surface is a smooth transition surface, can make things convenient for its moving on workplace like this, avoid workplace is caused damage.
In the such scheme, between a preferred leg 5-1 and the check-out console 3, be connected by the riveted joint mode respectively between No. two leg 5-2 and the benchmark flat board 1, the riveted joint mode connects to make and is connected to such an extent that more connect firmly between leg and the stationary plane, avoids bringing owing to the activity of one or several leg the decline of whole detection precision.Certainly, in actual use, also can select to be connected by screw, welding or other modes, as long as can realize that any mode that connects all should be within protection domain of the present utility model with between leg and the stationary plane.
Particularly, fixedly the mode of micrometer gauge 2 is on benchmark flat board 1, and the longitudinal hole that the test rod 2-1 for micrometer gauge 2 passes is set on benchmark flat board 1, is provided for the set screw 6 of fixed test bar 2-1 in the side of through hole.During installation, benchmark flat board 1 is lain against working face, with vertically pack into through hole on the benchmark flat board 1 of the test rod 2-1 of micrometer gauge 2, adjust the position of test rod 2-1, detection head and check-out console 3 are kept in touch, then set screw 6 is tightened test rod is fixed, promptly installed micrometer gauge.Before the detection, adjust the micrometer gauge pointer and make it to be designated as zero.
Described micrometer gauge 2 is the commodity that can buy on market, and its structure is known, and in the present embodiment, it is that 1 μ m, range are the micrometer gauge of 0～± 30 μ m or 0～± 50 μ m that micrometer gauge 2 is selected resolution.
In the said structure, preferred spring 4 is a springs, and springs can be realized flexural deformation better, thereby better detected working face alternate position spike is delivered to micrometer gauge by check-out console.During installation, make the junction of check-out console and benchmark flat board 1 reserve a little gap, the elastic force of springs is slightly less than the gravity of check-out console.When benchmark flat board and check-out console location were poor, springs is flexural deformation thereupon, and alternate position spike is passed to micrometer gauge by check-out console, and micrometer gauge just indicates the position extent.
In addition, heat insulation bat-handle 7 is set above benchmark flat board 1, heat insulation bat-handle 7 usefulness thermal insulation materials are made, and the heat insulation bat-handle 7 made is installed in the middle and upper part of benchmark flat board 1 by fixed mount 8, and heat insulation bat-handle 7 is connected with fixed mount 8, be connected by screw between fixed mount 8 and the benchmark flat board 1, like this, by using heat insulation bat-handle, just can conveniently mention and move this calibrating installation, prevent that simultaneously the hand heat from passing to the benchmark flat board and causing it to expand with heat and contract with cold, be out of shape, thereby influence accuracy of detection.
Describe the using method of calibrating installation described in the utility model below in detail, this method is followed successively by:
1, by heat insulation bat-handle 7 benchmark dull and stereotyped 1 and check-out console 3 are mentioned and lie against the working face of being examined and determine.
2, a circular leg 5-1 who confirms three circular leg 5-2 of benchmark flat board 1 and check-out console 3 falls within the working face of being examined and determine naturally and contacts.
3, the test rod of micrometer gauge 2 is packed into through hole on the benchmark flat board 1 is adjusted the position of test rod 2-1, and detection head and check-out console 3 are kept in touch, and set screw 6 is tightened, and the fixed test bar has just installed micrometer gauge 2.
4, adjust the zero point of micrometer gauge 2, can detect.
5, according to national metrological verification regulations " JJG117-2005 " requirement, promote this calibrating installation to each part of being examined and determine working face 9 by heat insulation bat-handle 7, check the indicated value of micrometer gauge 2 and write down it, promptly obtain each local plane wave momentum, meet the requirement of vertification regulation, then this assay approval as part plan degree undulate quantity.Otherwise it is defective.
