Abstract
The utility model discloses a mortar small specimen terminal surface anchor clamps of polishing specifically is applicable to the processing of the required small specimen of SHPB experiment. It comprises one section seamless steel pipe and gasket. Anchor clamps shell seamless steel pipe is the cylinder tube -shape, can with the fixed station phase -match of rock polisher, the seamless steel pipe both ends all are equipped with the recess, the outstanding internal diameter wall in recess bottom is equivalent to outstanding platform to hold the gasket, the depth of groove is greater than the gasket height, and the recess internal diameter is the same with the external diameter of gasket. Adopting this set anchor clamps rock small specimen of polishing, can solving the low shortcoming of the terminal surface depth of parallelism when polishing the small specimen, can solve the test piece simultaneously and meet the problem that the water inflation results in being difficult to to take out in the fixed head anchor clamps, these anchor clamps two test pieces of can polishing have simultaneously improved the efficiency of polishing in addition.
Description
Technical field
The utility model relates to the fixture of a kind of mortar small specimen end face polishing, and its body is applicable to the stationary fixture that SHPB tests small specimen end face polishing used.
Background technology
At present, when polishing tests small specimen used for SHPB, because sample dimensions is too little, common rock Double End sander is difficult to the position fixing small sample, thus cause the depth of parallelism of small sample two end faces to be difficult to control, very large impact is caused on experimental data, and is greater than the thickness of small sample due to the test specimen fixed station width of rock Double End sander, so the mode that small sample can only adopt one side to polish, grinding efficiency is very low.
Utility model content
Use rock Double End sander can not fix small-size test piece very well to overcome, cause faces parallel difference and the deficiency becoming sample inefficiency, the utility model provides a kind of fixture, the small specimen of different-diameter well can not only be fixed on rock Double End sander, ensure the depth of parallelism of test specimen end face, and two test specimens of can polishing the same time, improve into sample efficiency.
The utility model is made up of fixture shell seamless steel pipe, the groove at steel pipe two ends, platform, pad, described fixture shell seamless steel pipe two ends are provided with groove, the pad of different-thickness can be put into groove, platform just in time can hold pad thus the mortar specimen of different-thickness of can polishing.
The small sample of the applicable diameter 50mm of this sleeve clamp, depth of groove 10mm, has the pad of three kinds of gauges, is respectively 2.5mm, 5mm.Test specimen held by employing platform and pad can make sample uniform force, ensures the faces parallel of test specimen during polishing.This fixture adopts symmetrical design, and two test specimens of can simultaneously polishing, substantially increase working (machining) efficiency.

Detailed description of the invention
As shown in Figure 1, whole fixture adopts cylindrical housing (1), and fixture can match with the sample fixing device on the two-sided sander of rock.Fixture two ends are provided with groove (2), and the pad of different-thickness (4) can be put into groove (2), platform (3) just in time can hold pad (4), thus the mortar specimen of different-thickness of can polishing.
During polishing test specimen, test specimen is put into groove (2), and test specimen just in time can be clamped in groove (2), and abrasive disc grinds off in groove (2) unnecessary specimen thickness outward giving prominence to, and reaches the specimen thickness size wanted.
Claims (1)
1. a mortar small specimen end face grinding clamp, it is characterized in that: it is made up of the groove (2) at fixture shell seamless steel pipe (1), steel pipe two ends, platform (3), pad (4), described fixture shell seamless steel pipe (1) two ends are provided with groove (2), the pad of different-thickness (4) can be put into groove (2), platform (3) just in time can hold pad (4) thus the mortar specimen of different-thickness of can polishing.
