Description

A kind of New Rock thin slice clamping device

Technical field

Petrographic thin section production field is the utility model is related to, especially a kind of New Rock thin slice clamping device.

Background technology

Petrographic thin section is to carry out one of most basic data of geological analysis, and qualified petrographic thin section is for Correct Analysis geology Effect and geological process are extremely important.Although occurring some automatic, semi-automatic petrographic thin section sample-preparing systems at present, final FINISHED is required for by hand to correct or polish.Due to petrographic thin section（It is bonded on slide）It is very thin in fine grinding, use Hand is difficult to hold, can only by utilized on mill hand friction power restriction its rotate with mill, it is slightly careless may be high The mill that speed rotates is thrown away, and causes thin slice to damage, or even scratch hand；And in polishing, because polishing cloth frictional force is very big, it is difficult to With hand directly in polishing cloth（Disk）On be polished.Therefore, suitable clamping device for petrographic thin section final product quality very It is important.At present, the clamping device dedicated for manual grinding and polishing petrographic thin section is seldom, and the slide clamping of some semi-automated instruments is matched somebody with somebody Although part can be used for manual grinding and polishing, but more using duroplasts as material, it is first opaque, the thickness of petrographic thin section can not be observed Change, petrographic thin section surface is easily caused to tilt, second rigidity is inadequate, yielding, during edge stress is more than in hand-held force Portion, cause petrographic thin section thick middle, thin edge, became uneven.Therefore, it is necessary to a kind of clamping device, come ensure it is safe efficient, Petrographic thin section is completed in high quality to make.

The content of the invention

The purpose of this utility model is to provide a kind of New Rock thin slice clamping device, and it is thin that the device can improve rock Grinding quality and polishing efficiency, the effect of piece, while operator's hand can be protected to preserve from, make rock by hand so as to improve The yield rate and quality of stone thin slice.

Technical scheme includes used by the utility model：

A kind of New Rock thin slice clamping device, including pedestal, pedestal are made by glass, and plane configuration is rectangle, edge For inclined-plane, clamping face is dimpling sphere, and four sides are provided with draw point, each 2 draw points of long side, each 1 draw point of short side, wherein 1 short The draw point on side is movable draw point, is inserted in pin hole, and remaining 5 are fixed draw point.

Preferably, the glass pedestal edge is inclined plane, prevents from scratching hand and polishing cloth.

Preferably, the glass pedestal clamping face is dimpling sphere, center 5-10 microns higher than the edge, you can ensures thin slice The stress at middle part, and can ensure the absorption affinity of water between pedestal and slide.

Preferably, the draw point bare terminal end is spherical.

Preferably, described movable draw point one end is spherical that one end is disc shape, and disc shape diameter is bigger than draw point, can Limit it is spherical bring out dew it is long.

The beneficial effects of the utility model are：

The utility model provides a kind of New Rock thin slice clamping device, and glass pedestal is transparent, is easy to observation rock thin The thickness change of piece；Pedestal clamping face is dimpling sphere, and petrographic thin section can be avoided to occur thick middle, edge in erosion process Thin phenomenon；Draw point bare terminal end is spherical, prevents plowing from polishing cloth（Disk）；Movable draw point can plug, and be easy to remove slide； Device is integrally easy to handle, and improves operating efficiency and security.

Brief description of the drawings

The utility model is described in more detail below in conjunction with the accompanying drawings：

Fig. 1 is the dimensional structure diagram of the utility model petrographic thin section clamping device.

1 --- pedestal

2 --- susceptor edges inclined plane

3 --- fixed draw point

4 --- movable draw point.

Embodiment

The utility model discloses a kind of New Rock thin slice clamping device, in order that the advantages of the utility model, technology Scheme is clearer, clear and definite, and below in conjunction with the accompanying drawings and the utility model is specifically described instantiation, and example is only For explaining the utility model, the scope of the utility model is not intended to limit.

As shown in figure 1, the utility model petrographic thin section clamping device, including pedestal, pedestal are made by glass, plane configuration For rectangle, edge is inclined-plane, and clamping face is dimpling sphere, and four sides are provided with draw point, each 2 draw points of long side, each 1 steel of short side Pin, wherein the draw point of 1 short side is movable draw point, it is inserted in pin hole, remaining 5 are fixed draw point.Rock sample is ground During throwing, drench glass pedestal or slide with water, adsorb slide using the tension force of water, hand-held device is in mill or polishing cloth （Disk）Upper carry out grinding and polishing, while through the change of glass pedestal observation sheet thickness, avoid the occurrence of excessive thickness deviation；Need mirror During lower observation sheet thickness, movable draw point is somewhat extracted, promotes slide to remove it from another short side, if Microscopic observation The below standard standard of thickness, movable draw point under can putting it into device and inserting, continues grinding and polishing, until reaching standard thickness.

New Rock thin slice clamping device provided by the utility model, it is simple to operate, can be with more efficient, grinding and polishing in high quality Petrographic thin section, and reduce hand injuries.

It should be noted that under this specification teaching, any equivalents that those skilled in the art are made, Or obvious mode of texturing, all should be in the scope of protection of the utility model.
