Description
Technical field
This utility model relates to a kind of grinding and polishing clamp for column sample, belongs to field of material engineering technology.
Background technology
The vital step when preparation of sample is detection material microstructure structure and performance, quality prepared by sample directly influences the accuracy of subsequent detection result.In the great many of experiments of material tests, bar-shaped or column sample is the most common, use efficiency during free-hand grinding the lowest, quality is the most uneven, has a strong impact on efficiency and the reliability of detection.The particularly diameter tiny sample less than 5mm is the most extremely difficult when grinding, owing to treating that flour milling is the least with sand paper contact area, easily causes the defects such as grinding and polishing air spots, inclination, bevelling.In order to solve this problem, it usually needs sample to be carried out damascene process, but inlay and the process taken off is the most numerous and diverse, careless slightly will damage sample, be unfavorable for follow-up detection.
For solving the problems referred to above, Chinese utility model patent ZL201320365991.4 provides a kind of fixture grinding column metallographic specimen, but the sample aperture in this utility model is inner cylinder, cylinder sample is only fixed by cylindrical hole inwall and fastening bolt top in the process that grinds, it is in the state of linear contact lay at two, it is not sufficiently stable, may cause making sample produce slip relatively during grinding and polishing, thus affect efficiency and the quality of grinding and polishing.
Utility model content
For the problems referred to above, this utility model provides the grinding and polishing fixture of a kind of column sample tested for compression or metallographic, can be used to the detection sample of the experiments such as the batch compression of grinding and polishing column, metallographic.
The technical solution adopted in the utility model: as depicted in figs. 1 and 2, column sample grinds and includes cylindrical body and clamping screw with polishing clamp, chuck body is the cylinder of Φ 30 ~ 60 × 10 ~ 30mm, the circular arc using R 2 ~ 4 mm between upper bottom surface and sidewall is excessive, to sand paper and the damage of polishing cloth during to reduce grinding and polishing sample；Chuck body is provided with 2 ~ 8 hexagon through holes, the upper bottom surface of its through chuck body；Six limits of hexagon through hole are followed successively by a, b, c, d, e, f, and wherein, a=c=2 ~ 4 mm, f=d=5 ~ 8mm, e=1mm, b=3 ~ 5mm, limit e are parallel to each other with limit b, and the vertical dimension of limit e to limit b is 6 ~ 9mm；Limit b is near the outside of chuck body, and the distance of its distance chuck body side is 4 ~ 6mm, and limit e is near the center of chuck body；The side of each hexagon through hole vertically sets the tapped through hole of a M 3 ~ 5 at the 5 ~ 15mm of cylindrical body bottom surface, and the clamping screw being respectively equipped with a size of M 3 ~ 5 × 10 ~ 20mm is used for tightening and fixing sample.
Preferably, the material of described chuck body and clamping screw is stainless steel material, has good corrosion resistance.
Preferably, being carved with anti-skid design around described cylindrical body, the curable grip of fixture when can effectively promote grinding and polishing sample, described tapped through hole is evenly distributed in one week same level of body.
Preferably, the size of described clamping screw is M 3 ~ 5 × 10 ~ 20mm.
Specimen clamping hole is hexagon through hole, makes cylindric sample be in linear contact lay state at three when fastening, by action of compressive stress at three, more stable, overcomes sample completely and grinds the sliding phenomenon that process is likely to occur.
The accessible beneficial effect of this utility model:
(1) fixture described in the utility model uses large contact surface to substitute bar, the little of the most tiny bar treats grinding and polishing face, the problems such as the air spots, inclination, bevelling and the cylinder out of plumb that occur when can be effectively prevented grinding and polishing sample, and not easy damaged metallographic specimen, be difficult to scratch polishing cloth.
(2) fixture described in the utility model can prepare multiple sample simultaneously, substantially increases sample preparation efficiency and batch quality stability.
(3) clamp structure described in the utility model is succinct, easy to use, and clamping is stable, with low cost.
(4) fixture described in the utility model uses stainless steel material to prepare, and has good corrosion resistance.
