Description
Technical field
Compressive strength is one of index the most basic in rock, concrete material mechanical strength.The present invention relates to material and carry out Mechanics Performance Testing field, particularly relate to the proving installation of the sample parallel such as rock, concrete degree.
Background technology
Compressive strength is one of index the most basic in rock, concrete material mechanical strength, for the characteristic evaluating rock material, and concrete strength grade, and whether be suitable in engineering and have great importance.
In the intensity test of laboratory, rock type materials commonly uses diameter 50mm, the cylinder specimen of height 100mm, concrete material commonly uses 100mm cube specimen, for cylindrical rock sample, mostly be by getting core to protolith, end face polishes and processes, concrete material is also built by the mould of certain size and is prepared from, but no matter be rock or concrete material, in processing, in preparation process, many depth of parallelisms simply being measured test specimen by slide calliper rule, even pass through visual assessment, error is larger, due to machining precision, prepare the reasons such as mould irregularity and artifact, many samples processed are caused to place on testing machine loading bench, just find when test specimen contacts with testing machine platen that the depth of parallelism of test specimen both ends of the surface is poor, and material upper and lower pressure-bearing end face is not parallel, test specimen eccentric compression can be caused during test, not only cannot obtain the actual strength of material, waste a large amount of manpowers simultaneously, material resources and financial resources.Therefore, test specimen carry out before testing the depth of parallelism measure most important.
But lack the device that Mechanics Performance Testing sample parallel degree is detected at present, the existing pick-up unit to the depth of parallelism such as automobile chassis, revolving body workpieces is not suitable for the detection of the sample faces parallels such as rock, therefore, invent a kind of structure sample parallel degree pick-up unit that is simple, easy to operate and degree of precision and there is higher actual application value.
Summary of the invention
The object of the present invention is to provide a kind of sample parallel degree proving installation, measuring method is simple, and easy to operate, reliability is high.
To achieve these goals, technical solution of the present invention is:
1, a sample parallel degree proving installation, comprises the mechanism for testing that cup dolly, column and upper disk are formed, and cup dolly is carved with square and circular groove.Described base is welded with column along two ends, and base and column are fixed together, and test sample is placed on base; Column with chute, embedded slide bar, slide bar and chute gap less; Upper disk is identical with base diameter, and described upper disk is connected by bolt with slide bar, can realize disk and slide bar moving up and down in column chute.
2, further, upper disk has threaded hole at two ends, is fixed on column after adjusting the position of disk by bolt by upper disk, and slide bar also plays and keeps upper disk and cup dolly centering and parallel effect.
3, further, described upper disk centrally cross crotch is opened by line.
Further beneficial effect of the present invention is: after upper disk contacts with surface of test piece, by rule, the pit gauge that can be vernier caliper inserts in the cross crotch that above disk is opened, thus obtains the relative height value of surperficial each point, for the depth of parallelism of further accurately judgement sample provides experimental data.

Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further;
1, as shown in Figure 1, the invention provides a kind of sample parallel degree proving installation, comprise the mechanism for testing that cup dolly (1) and column (2) and upper disk (3) are formed, described cup dolly (1) is carved with square and circular groove, base (1) is welded with column (2) along two ends, both base (1) and column (2) are fixed together; Column (2) with chute (4), embedded slide bar (5); Upper disk (3) is identical with base (1) diameter, described upper disk (3) is connected by bolt with slide bar (5), can realize disk (3) and slide bar (5) moving up and down in column (2) chute.
2, described upper disk (3) has threaded hole at two ends, by bolt (6), upper disk (3) and slide bar (4) are fixed on column (2), and keep with the centering of cup dolly (1) with parallel.
3, described upper disk (3) centrally cross crotch is opened by line, and this seam can insert rule, and described rule can be the pit gauge of vernier caliper.
When adopting the sample parallel degree proving installation test sample depth of parallelism:
The first step, upper disk (3) is connected by bolt with slide bar (5), and disk and slide bar can be made to move up and down in column (2) chute.First upper disk (3) is risen, so that test sample can be placed, then sample is placed on base (1), and by sample shape, the cube on its lower surface and base (1) or circular groove are overlapped.
Second step, disk (3) in movement, treat that disk (3) contacts completely with the upper surface of testing sample, if the depth of parallelism of sample end face is good, then the upper surface of sample and upper disk (3) can be combined closely, if the depth of parallelism is poor, then have gap between the upper surface of sample and upper disk (3), now bolt on (6), upper disk (3) is fixed on (2) on column.
3rd step, the cross crotch of rule by upper disk (3) is contacted with the upper surface of testing sample, described rule can be the pit gauge of vernier caliper, measure one end, opposite along one end of a seam in upper disk cross crotch always, optionally measure several point, as the end points of sample, several representative locations such as 1/4 point, central point of sample length (diameter), by measuring the distance of sample end face to upper disk upper surface, the relative height value (namely the unified upper surface of upper disk that adopts is as reference level) on testing sample surface can be obtained.Take same method, in measurement, the relative height of sample surfaces below the other groove of the cross crotch of disk, after completing above measurement, namely can be and determines that the error amount of sample upper and lower surface flatness provides experimental data.
The above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the common engineering technical personnel in this area, to the various distortion made of technical scheme of invention and improvement, all should fall in protection domain that claims of the present invention determine.
