In the actual operation process of observing the coating on the surface of the workpiece based on the mosaic observation method, the condition that the color of the coating is relatively close to that of the filler of the metallographic mosaic machine often exists. Such a situation results in that the sample processed by the metallographic mosaic machine cannot accurately acquire the coating region under the measuring instrument, and thus a large measurement error is always caused. The present embodiment is therefore directed to a sample processing device suitable for a metallographic mosaic machine, which overcomes the above-mentioned technical drawbacks.

The sample processing device suitable for a metallographic mosaic machine disclosed by the utility model is further specifically described below with reference to the embodiment shown in the drawings.

As shown in fig. 1, the sample processing devices each include: a supporting plate 1, a screw rod 2, a pair of clamping pieces 3 and a cladding piece. In a specific structural arrangement, the screw rod 2 is arranged on the support plate 1 in a penetrating manner along the horizontal direction, and has the freedom of rotating along the circumferential direction of the screw rod. The pair of clamping pieces 3 are sleeved on the screw rod 2, wherein one clamping piece 3 is fixedly sleeved, and the other clamping piece 3 is in threaded movable fit with the screw rod 2. The cladding piece is arranged between the clamping pieces 3, two ends of the cladding piece extend upwards along the clamping faces of the clamping pieces 3 respectively, and the cladding piece has high contrast with a plating layer on the surface of the sample.

Based on the sample processing device, when inlay measurement is required, first, a clad member having a high contrast with the sample surface plating layer is selected. Then, it is placed between the pair of holders 3, and then the sample is placed on the sheathing member. Then, the clamping piece 3 which is in threaded fit with the screw rod 2 is controlled to clamp so that the cladding piece is tightly attached to the observation surface of the sample. At this time, when the filler of the embedding machine is embedded, the coating piece forms a barrier layer between the film layer to be detected of the sample and the filler to realize clear distinction between the film layer to be detected of the sample and the filler. And then, the characteristic parameter values such as the tissue or the thickness of the film to be measured can be accurately obtained when the film is observed by means of a measuring instrument.

Specifically, in this embodiment, the contrast between the clad member and the plating layer on the surface of the sample is higher than 60%. As a specific embodiment, when the plating layer on the surface of the sample is a phosphating film layer or a nitriding film layer, the corresponding cladding member is tin foil. At the moment, the tin poise not only can meet the observation requirement, but also has the advantages of low cost and easiness in clamping and attaching to the surface of a plating layer.

For example, the cover member is generally flexible, so that the sample processing device may further comprise a placement plate for facilitating placement. The placing plate is arranged on the pair of clamping pieces in a penetrating mode in an interference mode, and two ends of the placing plate are fixed with the limiting pieces respectively and used for placing the wrapping pieces. At this time, when the wrapping piece is placed, the middle of the wrapping piece is placed on the placing plate, and the two ends of the wrapping piece exceed the spare ends of the clamping piece.

In addition, the clamping piece can clamp the rear cladding piece and the observation surface of the sample to have good and tight adhesion. The clamping piece 3 is made of hard metal, and the surface of the clamping piece is plated with a hard smooth coating. Meanwhile, on the other hand, since the surface shape of the sample after cutting varies, it may be a planar structure or an arc structure. Therefore, the coating member can be tightly attached to the observation surface of the sample under the clamping action of the clamping member 3. The pair of clamping pieces 3 are provided with replaceable structures, and the clamping surfaces of the clamping pieces 3 are matched with the shape of the observation surface of the sample.

In order to prevent the movable clamping element 3 from moving to the thread boundary of the spindle 2 and thus affecting the clamping action. The sample processing device is further provided with a stop 4. The limiting piece 4 is fixed on the supporting plate 1 and arranged on the outer side of the clamping piece 3 in threaded movable fit with the screw rod 2. At this time, the limiting member 4 will have a certain limiting effect on the movably arranged clamping member 3.

As a preferred embodiment, the screw 2 is a bidirectional screw to improve the clamping efficiency. Specifically, the screw thread on one side of the bidirectional screw rod is a left-handed screw thread, and the screw thread on the other side of the bidirectional screw rod is a right-handed screw thread. One clamping piece 3 of the pair of clamping pieces 3 is matched with left-handed threads on one side of the bidirectional screw rod; the other clamping piece 3 is matched with the right-handed thread on the other side of the bidirectional screw rod. At this time, the pair of clamps will move toward each other at the same time when the clamping movement of the clamp 3 is performed as compared to the sheathing member. The pair of stoppers 4 are also provided on the outer sides of the holders 3.

In order to facilitate the clamping operation, the sample processing device is provided with a further lever 5. The surface of the operating rod 5 is of a non-smooth structure, and the operating rod 5 is fixedly arranged at one end of the screw rod 2. At this time, the screw rod 2 can be driven to rotate only by rotating the operating rod 5, so that the clamping piece 3 is driven to perform clamping movement, and the cladding piece is attached to the observation surface of the sample.

As an alternative embodiment, the operating lever 5 can be replaced by a drive element. Specifically, the driving piece is a rotating motor, and the rotating motor is matched with the screw rod. At this time, the screw rod 2 can be driven to rotate only by starting the rotating motor, and then the clamping piece 3 is driven to perform clamping movement so that the cladding piece is attached to the observation surface of the sample.

In order to prevent displacement of the sample processing device during clamping movement of the clamping member 3, it is provided that it further comprises a fixing hole 6. The fixing holes 6 are formed in the support plate 1 in a penetrating manner in the vertical direction, so that the support plate 1 is fixed on the carrying platform through fixing pieces penetrating through the fixing holes. In this embodiment, the number of the fixing holes 6 is four, and the fixing holes are uniformly spaced along the circumferential direction of the support plate 1; the fixing piece is specifically a bolt.

As an embodiment that can rotate, the fixing hole 6 can be replaced by a buckle provided at the edge of the support plate 1. At this time, the supporting plate 1 is only required to be clamped and fixed on the carrying platform through the buckle.

The embodiment also provides a metallographic mosaic machine. The metallographic mosaic machine comprises the sample treatment apparatus for sample pretreatment.

Specifically, when the metallographic mosaic machine is used for mosaic observation, firstly, a sample is preprocessed through the sample processing device in the mode described above. Then, starting a power supply of the metallographic mosaic machine to heat the metallographic mosaic machine to a preset temperature; the lower die is controlled to be parallel to the lower platform, and the sample observation surface is placed downwards; adjusting the lower die and the lower platform to sink, and adding filler; and then controlling the upper die to sink and compact, thus completing the embedding process of the metallographic embedding machine on the sample. And taking out the sample with the embedded filler, grinding and polishing the sample, and then placing the sample under a measuring instrument for observation.

In the embodiment, when the plating layer of the workpiece is a phosphate film, the phosphate film structure cannot be seen under a 200 x lens when the workpiece is directly observed through a measuring instrument after being sequentially cut, inlaid and polished; when the workpiece is sequentially cut, subjected to tin foil cladding treatment based on the sample treatment apparatus, inlaid and polished and then observed by a measuring instrument, a phosphated film structure with the thickness of 18 micrometers can be clearly observed under a 200X-times mirror.

When the plating layer of the workpiece is a nitride film, the workpiece is directly cut, inlaid and polished in sequence and then is observed through a measuring instrument, only a fuzzy plating layer structure can be observed under a 200X-times mirror, and the thickness of the plating layer is measured to be 10 microns; when the workpiece is sequentially cut, subjected to tin foil cladding treatment based on the sample treatment apparatus, inlaid and polished, and then observed by a measuring instrument, the coating structure can be clearly observed under a 200X-times mirror, and the thickness of the coating is measured to be 28 microns.

Therefore, after the sample pretreatment is performed on the basis of the sample pretreatment apparatus disclosed by the embodiment, the observability and the measurement precision of the surface coating of the workpiece can be effectively improved.

While the utility model has been described with reference to preferred embodiments, it is not intended to be limiting. Those skilled in the art will appreciate that various modifications and adaptations can be made without departing from the spirit and scope of the present utility model. Accordingly, the scope of the utility model is defined by the appended claims.
