Detect: solidify state embedding medium to replace detecting tiny position with detecting instrument direct-detection.
When making section or ultra-thin section, because tissue is soft, or the soft or hard of local is uneven, and making thickness is cut into slices uniformly is like this difficult.So be necessary to soak into organization internal with certain material, whole organizing equally is hardened, and is beneficial to thinly slice, and this material is called embedding medium.Die and embedding medium with the use of, accurately copy tiny position shape, partial copy is carried out at the tiny position not easily measured by large product, is made into sample block, then detects sample block.Embedding medium is mainly used in physical and chemical inspection metallographic specimen and makes, and the present invention expands the usable range of embedding medium, and described cavity is for holding embedding medium.
Preferred as technique scheme, described processing die step is also included on described die and arranges detection reference face, described detection reference face, as placement bottom surface when detecting, makes to solidify state embedding medium and is in the convenient position detected, and prevents from producing when using profile measurer to detect interfering.
Preferred as technique scheme, described processing die step is also included in described die arranges to clear up and detects the complete cleaning eye solidifying state embedding medium.
Described cleaning eye can be threaded hole, and sample block detects complete, and with screw, embedding medium solidifying body can be ejected, die can reuse
Preferred as technique scheme, powder, water that the pre-gelatinized starch of paraffin powder or gel powder and 90%-10% that the raw material of described making embedding medium comprises 10%-90% is mixed.
Preferred as technique scheme, powder, water that the pre-gelatinized starch of paraffin powder or gel powder and 40%-10% that the raw material of described making embedding medium comprises 60%-90% is mixed.
Preferred as technique scheme, in described molding step before pouring liquid embedding medium into, by the position blocking agent of the liquid embedding medium of seepage carrying out shutoff process, prevents embedding medium seepage.
Preferred as technique scheme, described blocking agent is plasticine.
Preferred as technique scheme, described detecting instrument is profile measurer or length measuring instrument.
In sum, the present invention has following beneficial effect:
1. the tiny location detection method of a kind of workpiece of the present invention is easy and simple to handle, and testing cost is low;
2. the tiny location detection method of a kind of workpiece of the present invention is easy to realize accurate detection;
3. the tiny location detection method of a kind of workpiece of the present invention is applied widely, can make corresponding die according to ceaselessly workpiece.
