This paper relates to a fixing device used to grind specimens for ultra-thin plates, and in more detail, a holder connection member which has a tightening interval adjusting rod being struck in the inner center of the cylindrical specimen gap adjusting holder and screwed downward. The specimen clamping grooves in which the c-grooves are inserted on both sides are interposed between the copper wire and the ultra-thin plate by inserting the specimen connecting rod into the insertion hole inside the specimen clamp holder inside the specimen clamp holder and adjusting the specimen gap. By turning the holder, the specimen and the malleable copper plate are fixed tightly at a uniform pressure so that the ultra-thin plate can not be rounded during grinding. Pipes with ultra-thin specimen grinding fixtures for easy observation of the entire surface texture. Will.

In the conventional fastening device for grinding the ultra-thin plate specimen, it was made of a structure that performs the polishing after fixing the specimen by fixing the specimen for the ultra-thin plate using two bolts (Bolt).

Therefore, when the worker fixes the bolt with bolts, the two bolts cannot be tightened at the same time, so that they cannot be fixed at the same pressure on the specimen, and the size of the specimen must be constant at all times. There is a problem in that a part of the specimen itself is compressed due to the pressure, the organizational change occurs, and there is a difficulty in arranging a plurality of ultra-thin plates.

In addition, there was a problem in that the corrosion solution leaked between the gaps of the sample when the specimen was etched, so that the entire surface structure could not be easily observed.

The present invention is devised to improve the conventional conditions and problems as described above, the purpose is to simply and quickly fasten the specimen to fix it, the corrosion solution does not leak between the gap of the sample during etching, the whole specimen The surface structure of the specimen can be easily observed, and the specimen holding device itself is a disk type, so that the specimen polishing operation can be performed quickly and conveniently when polishing the ultra thin plate, plating layer, oxide layer, and decarburized layer. To provide a device.

In order to achieve the above object, the present invention, the female thread is formed on the inner lower side of the cylindrical specimen gap-adjustment holder is formed, the hole is formed in the center of the upper side of the holder connector is assembled to the lower side, the male side is formed on the outer peripheral surface The internal thread portion is formed in the step portion and the inside, while the male thread portion is formed on the upper side of the specimen clamp holder coupled to the female screw portion of the holder connector, the specimen clamp is mounted in the center to fix the malleable copper plate and ultra-thin plate specimen In the ultra-thin plate specimen fixing device, a clamping interval adjusting rod is formed at the center of the specimen gap adjusting holder to enter the hole of the holder connector; The specimen clamping plate is formed with a c-shaped groove on the inner side and a flat inclined surface on the outer side to be fitted into the specimen clamping slot insertion hole of the specimen clamping holder having a rectangular tapered hole shape; The c-type groove is inserted into the specimen connecting rod and the malleable copper plate and the ultra-thin plate specimen is mounted to the lower side, the tightening interval adjusting rod advances the specimen connecting rod, so that the specimen tightening plate in the left, right direction to the said malleable copper plate and the ultra-thin plate specimen By providing a fastening device for grinding ultra-thin specimens characterized in that the fixing stenosis.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional front view of the ultra-thin specimen polishing fixture according to the present invention, and FIG. 2 is a partially cutaway exploded perspective view of the ultra-thin specimen polishing fixture. A female thread (3a) is formed in the lower side of the inside 1), the tightening interval adjusting rod (4) is vertically extended in the center, the hole (6) in the center of the upper side of the holder connector 5 is assembled A test piece tightening holder 10 coupled to the female threaded portion 8a of the holder connector 5 while a stepped portion 7 and a female threaded portion 8a are formed at a lower side with a male screw 3b formed on the periphery thereof. A male screw portion 8b is provided on the upper side of the upper side, and a specimen clamping rod insertion hole 9 having a rectangular tapered hole shape is inclined downward in the upper center thereof, as well as a tapered specimen inclined downwardly inserted therein. C-shaped groove (12) on one side of the lease (11), the specimen connecting rod (13) Is inserted into the outer surface to form a flat inclined surface, the lower side is composed of a configuration in which the malleable copper plate 14 and the ultra-thin plate specimen (15).

Referring to the operation and effects of the present invention made of such a configuration as follows.

As shown in FIG. 1 and FIG. 2, the specimen connecting rod 13 is inserted into the c-groove 12 formed at one side of the lower tapered specimen clamping table 11, and the malleable copper plate 14 is lowered. ) And the specimen 15 are arranged in close contact with each other at a suitable thickness, and then insert the specimen clamping table 11 coupled as described above into the specimen clamping insertion hole 9 of the specimen clamping holder 10.

Subsequently, after affixing and fixing the male screw portion 8b of the specimen clamp holder 10 using the female screw portion 8a formed at the inner bottom portion of the holder connector 5, the cylindrical shape with the nuring ring 2 was formed. When the specimen gap adjusting holder 1 is rotated while the female screw 3a formed at the inner lower side of the specimen gap adjusting holder 1 is combined with the holder connector 5 and the male screw 3b, the tightening gap adjusting rod 4 ) Pushes the specimen connecting rod 13 coupled to the specimen clamping plate 11 as it moves forward, thereby allowing the specimen clamping plate 11 to be inserted into the lower side in the left and right directions. ) Is firmly fixed by close contact with each other.

Therefore, when polishing the specimen 15, it is possible to perform the polishing operation without the rounding is generated in the copper plate 14 and the specimen 15 is firmly fixed.

As described above, according to the ultra-thin plate specimen fixing device of the present invention, the tightening interval adjusting rod is spoken to the inner center of the cylindrical specimen gap adjusting holder in which knurling is formed, and is screwed downward. Specimens clamping plate with c-groove in which the specimen connector is inserted through the holder connector is coupled to both sides to insert the specimen for natural copper plate and ultra-thin plate, and to insert it into the specimen clamping hole insertion hole inside the specimen clamp holder. By rotating the spacing holder, the malleable copper plate sandwiched between the specimen and the specimen is tightly adjusted to uniform pressure so that ultra-thin specimens with a thickness of 6 mm or less are not rounded and polished simply and quickly. In addition, the corrosion solution does not leak between the gaps of the sample during etching, and the surface texture of the entire specimen can be easily observed. And will have an excellent effect that can specimen holding device itself consists of a disc type is convenient at the time of polishing the electrode sheet, the plating layer, the oxide layer and the tantalum layer, and quickly perform specimen grinding.
