Displacement meter calibration instrument is mainly used in industrial occasions and scientific research places, and its purpose is to calibrate displacement meters of various principles. The electronic part is a grating ruler, and the other parts are components made of stainless steel, including one left and right vertical plate, two guide rails, two displacement gauge fixed cards, and one paddle. When working, fix the displacement meter with a fixed card, push the grating ruler digital display meter, and drive the displacement meter guide rod to move, and then calculate the sensitivity of the displacement meter through the digital display meter data and the output value of the displacement meter collected by the data acquisition system. Thus, the calibration of the displacement meter is completed.

Description

The displacement meter calibration instrument
Technical field:
The present invention is the displacement meter calibration instrument, is a kind of instrumentation of a kind of demarcation displacement meter (also being displacement transducer), is mainly used in industrial occasions the sensitivity of the displacement meters such as strain-type, slide wire resistance formula is demarcated.
Background technology:
In the production and process of scientific research of modern industry occasion, various displacement meters use very general, and it changes into electric signal with displacement, passes to data acquisition system (DAS) through wire, finally passes to computer, and storage on computers.Displacement meter in the process of using, aging along with the prolongation of service time and electronic component, sensitivity coefficient often can change, and such as untimely change sensitivity coefficient, will cause the data deviation measured larger, impact is used.
Present displacement meter for 50～500mm range, also there is not special-purpose calibrating instrument on the market, scaling method commonly used has two kinds at present: (1) adopts vernier caliper or other length measuring instruments, cooperates instrument and the materials such as Magnetic gauge stand, iron block, forms interim caliberating device; (2) with screw micrometer or calibrated bolck, cooperate the other materials such as Magnetic gauge stand, displacement meter is carried out segmentation demarcate.Demarcate scaling method for these two kinds, not only make the content that assembling is installed before demarcating very loaded down with trivial details, and often because the changing of the relative positions of makeshift device causes nominal data inaccurate.In the scientific research and testing process of engineering structure, sometimes need once to use up to a hundred displacement meters, for guarantee data accurately, each displacement meter needs to demarcate, workload is very large, is badly in need of a kind of quick and easy, displacement meter calibration device accurately.
Summary of the invention:
The displacement meter calibration instrument comprises each one of left and right sides riser, two on guide rail, two of displacement meter fixed cards, one of plectrum, one of digital display grating rule (seeing Fig. 1,2,3,4).Wherein left and right sides riser is made by stainless steel, thickness 10mm; Guide rail is made by stainless steel, diameter 12mm; Plectrum (seeing Fig. 5,6,7,8) is that the stainless steel substrates of 3mm is welded by thickness; Fixed card (seeing Fig. 9,10) is made by high strength steel.According to demarcating needs, the present invention can demarcate two displacement meters simultaneously, also can be in the situation that a known displacement meter sensitivity coefficient is demarcated another displacement meter.

Embodiment:
Displacement meter is fixed on the displacement meter fixed card, if displacement meter is longer, the displacement meter afterbody can be stretched out from the cavity in the middle of the right riser, the displacement meter guide rod is withstood on the plectrum (see Figure 11,12,13), the displacement meter wire links to each other with acquisition instrument.Promote the grating scale dial plate, the grating scale digital display meter namely shows mobile displacement, and plectrum promotion displacement meter guide rod moves under the dial plate, and data collecting instrument gathers displacement meter strain or voltage change simultaneously, by calculating the sensitivity coefficient that can draw displacement meter.If the sensitivity coefficient of a known displacement meter, with this sensitivity coefficient input Acquisition Instrument, when promoting dial plate, data collecting instrument can record the output signal of plectrum moving displacement and another displacement meter automatically, can directly pass through computer displacement calculating meter sensitivity coefficient.
