Description

Apparatus for holding sample "

The present invention relates to a sample fixing device, and more particularly, to a sample fixing device for quickly and easily pressing or fixing a sample by air pressure.

After conducting various experiments on steel and non-ferrous materials, we perform microscopic biopsy for the purpose of tissue change and quality analysis.

One side of the hole 2a is opened, It is possible to fix the inserted mounting specimen 1 as the area of the hole 2a is reduced by fastening the bolt 4 fastened to the side surface of the jig 2 with the slit 2b, .

On the other hand, in order to smoothly polish the lower portion of the mounting sample 1 during polishing, the mounting sample 1 is protruded downward by a certain amount from the hole 2a inserted therein. In order to uniformly polish the plurality of mounting samples 1, Level adjustment.

However, it takes much time and effort to fix the mounting sample 1 to the plurality of holes 2a formed at regular intervals on the surface of the jig 2 through the rotation of the bolts 4. [

In particular, it is very difficult to adjust the entirety of the mounting specimen 1 to a certain level while fixing each of the mounting specimens 1 individually, and the work load of the operator is rapidly increased in the course of repeating such operations for each sample 1 .

Since the mounting sample 1 is fixed to the hole 2a formed in the jig 2 through the assembly of the bolts 4 due to the variation in size (diameter) of the mounting sample 1, Since the jig according to the size of the mounting sample 1 needs to be replaced, there are limitations in that various jigs are required depending on the diameters of the holes 2a.
