Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metallographic detection technology, especially to sample observation fixture. BACKGROUND

[0002] Metallography mainly refers to the analysis research and characterization of material microstructure, low-magnification structure and fracture structure by means of optical (metallographic) microscope and stereoscopic microscope, etc., which contains not only imaging and qualitative and quantitative characterization of material microstructure, but also necessary sample preparation, preparation and sampling method. It mainly reflects and characterizes the number, morphology, size, distribution, orientation, spatial arrangement state of phase and organization composition, grain (also including possible subcrystal), non-metallic inclusions and even some crystal defects (such as dislocation) constituting the material.

[0003] When the metallographic sample is analyzed and observed, the metallographic sample needs to be polished for observation. In many cases, the observation surface of the polished metallographic sample is in an inclined state, so that the metallographic sample presents a case that one surface is a plane and the other surface is an inclined plane. When the inclined observation surface is analyzed by using a microscope, the observation surface needs to be kept horizontal to ensure the accuracy of metallographic analysis of the microscope, which makes the fixation of the metallographic sample particularly important. The existing observation fixture has a complex structure and is inconvenient to adjust, which greatly reduces the efficiency of metallographic analysis. UTILITY MODEL CONTENT

[0004] The utility model aims at overcoming the defects of the prior art and provides a sample observation fixture.

[0005] The utility model is realized by the following technical scheme:

[0006] The sample observation fixture comprises a supporting member and an observation platform arranged at the upper end of the supporting member, and a sample placing space is arranged between the supporting member and the observation platform;

[0007] At least one observation hole is formed in the surface of the observation platform, at least one flange is arranged at the inner wall top end of the observation hole, and the flange is used for limiting the observation surface of the metallographic sample;

[0008] At least one elastic supporting member is arranged on the surface of the supporting member, and the elastic supporting member is used for supporting the metallographic sample so that the observation surface of the metallographic sample abuts against the bottom surface of the flange.

[0009] A further optimization scheme of the technical scheme is that the observation hole is arranged at the edge position of the observation platform, and the observation hole is a non-closed hole.

[0010] A further optimization scheme of the technical scheme is that a buffer space is further concavely arranged in the inner side of the inner wall of the observation hole.

[0011] A further optimization of this technical solution is as follows: the flange is arranged in a ring shape.

[0012] A further optimization of this technical solution is as follows: the top of the inner wall of the observation hole is provided with at least three flanges, which are arranged in a triangular shape.

[0013] A further optimization of this technical solution is as follows: the elastic support is fixed to the upper end of the support member by fasteners.

[0014] A further optimization of this technical solution is as follows: the elastic support component is a U-shaped, Z-shaped, or L-shaped structure.

[0015] A further optimization of this technical solution is that the top surface of the elastic support is arc-shaped.

[0016] A further optimization of this technical solution is as follows: there are at least three elastic support members, the elastic support members are an integral structure, the elastic support members include a fixing part and a support part set at its upper end, the support part is an L-shaped structure, and the support part is set at an inclination.

[0017] This utility model discloses a sample observation fixture, which, compared with the prior art:

[0018] This technical solution utilizes an elastic support component in conjunction with a flange design. The flange serves as the observation surface for the metallographic sample, while the elastic support component continuously applies force to the sample, ensuring that the observation surface of the sample remains in contact with the bottom surface of the flange. This guarantees the stability and accuracy of metallographic analysis and observation. Furthermore, the elastic support component and flange design makes it easier to fix the metallographic sample and facilitates its placement and removal. Attached Figure Description

[0028] Example 1:

[0029] See Figures 1 to 4 As shown, this technical solution discloses a sample observation fixture, including a support member 100 and an observation platform 200 disposed on its upper end. A sample placement space 300 is provided between the support member 100 and the observation platform 200. At least one observation hole 201 is opened on the surface of the observation platform 200, and the observation hole 201 is connected to the sample placement space 300. At least one flange 202 is provided at the top of the inner wall of the observation hole 201, and the flange 202 is used to limit the observation surface of the metallographic sample. At least one elastic support member 400 is provided on the surface of the support member 100, and the elastic support member 400 is used to provide support for the metallographic sample so that the observation surface of the metallographic sample abuts against the bottom surface of the flange 202.

[0030] In the above technical solution, both the support member 100 and the observation platform 200 are rectangular plate structures and are arranged parallel to each other. The support member 100 and the observation platform 200 are connected by a support block. The surface of the observation platform 200 is horizontal, and the bottom surface of the flange 202 is parallel to the observation platform 200. In actual use, the entire fixture is first placed under the microscope, and then the metallographic sample is manually inserted from the outside into the sample placement space 300. The elastic support member 400 is located inside the sample placement space 300. The metallographic sample comes into contact with the elastic support member 400, causing the elastic support member 400 to deform (at this time, the deformation of the elastic support member 400 is mainly caused by human intervention). Next, the metallographic sample is slightly rotated for initial... After calibration, the manual pressure on the metallographic sample and the elastic support 400 is removed. Due to the elasticity of the elastic support 400, it applies an upward force to the metallographic sample. Because of the flange 202, the observation surface (tilted surface) of the metallographic sample will contact the bottom surface of the flange 202 due to the action of the elastic support 400. The continuous action of the elastic support 400 ensures that the observation surface of the metallographic sample remains parallel to the top surface of the observation platform 200, facilitating metallographic analysis under a microscope. When the metallographic sample needs to be removed, it can be easily taken out by simply pressing it down. When using the fixture for observation, the tilt angle of the back of the observation surface is 0-30 degrees. Similarly, the tilt angle of the observation surface polished from the metallographic sample is also 0-30 degrees.

[0031] See Figures 1 to 3 As shown, the observation hole 201 is located at the edge of the observation platform 200 and is not closed. As a preferred embodiment, the observation hole 201 is a semi-circular hole and is not closed, which allows the metallographic sample to be directly inserted into the sample placement space 300 from the side, which facilitates the placement and removal of the metallographic sample and the rotation of the metallographic sample for calibration.

[0032] See Figure 3 As shown, a buffer space is also recessed on the inner side of the inner wall of the observation hole 201; in the above technical solution, since the observation surface of the metallographic sample is in an inclined state, in order to make the observation surface parallel to the observation platform, the metallographic sample will be in an inclined state when the elastic support 400 applies force to the metallographic sample, and the setting of the buffer space can provide an activity space for the metallographic sample; as a preferred solution, the buffer space is an arc-shaped structure.

[0033] See Figures 1 to 3 As shown, the flange 202 is arranged in a ring shape. In the above technical solution, the ring-shaped flange 202 can better limit the observation surface of the metallographic sample to ensure that the observation surface is always horizontal, which is convenient for subsequent metallographic analysis and observation under a microscope.

[0034] As another preferred embodiment of the flange 202, the present technical solution has three flanges 202, and the three flanges 202 are arranged in a triangular shape. The arrangement of the three flanges 202 can also limit the observation surface. In addition, the three flanges 202 can also be arranged in other forms.

[0035] See Figures 1 to 4 As shown, the elastic support 400 is fixed to the upper end of the support member 100 by fasteners; in the above technical solution, the fasteners are bolts, and the elastic support 400 is fixed by the fasteners to realize the detachability of the elastic support 400. When dealing with metallographic samples of different specifications, the elastic support 400 can be replaced; as a preferred solution, the elastic support 400 is made of metal or non-metal material, and the metal material is iron, stainless steel or copper.

[0036] See Figure 4 As shown, the elastic support 400 has a U-shaped structure; in the above technical solution, the elastic support 400 has a U-shaped plate structure and is an integral structure. The elastic support 400 includes a base plate, which is connected to the support member 100. The upper end of the base plate is provided with an elastic part, which is inclined to the base plate. The upper end of the elastic part is provided with a buffer part, which is at a 90-degree angle to the elastic part.

[0037] See Figure 4 As shown, the top surface of the elastic support 400 is arc-shaped; the arc-shaped design prevents the elastic support 400 from damaging the metallographic sample.

[0038] Example 2:

[0039] See Figure 5 As shown, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 has at least three elastic support members 400. The elastic support member 400 is an integral structure, including a fixing part and a support part disposed on its upper end. The support part has an L-shaped structure and is inclined. In the above technical solution, the three elastic support members 400 can provide better support for the metallographic sample, so that the observation surface of the metallographic sample abuts against the bottom surface of the flange 202 and is not easy to loosen.

[0040] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
