Technical Field

[0001] The utility model provides a metallographic microscope sample positioning device, belonging to the technical field of metallographic microscopes. Background Art

[0002] The metallographic microscope is a high-tech product developed by perfectly combining optical microscope technology, photoelectric conversion technology, and computer image processing technology. It can be used to analyze the relationship between the organization of steel and its chemical composition by examining the organizational morphology; it can determine the microstructure of various types of steel after different processing and heat treatment; and it can judge the quality of steel by observing the distribution and quantity of various types of steel inclusions - oxides, sulfides, etc. in the organization and the size of metal grains.

[0003] At present, when using a metallographic microscope to observe a sample, in order to position the sample, a sheet clamp is usually used, and the sample is pressed between the sheet clamp and the stage plate by its own gravity. However, due to its relatively light weight, the pressure is relatively small, and it is impossible to firmly and stably press the sample between the sheet clamp and the stage plate, which easily causes the sample position to shift due to external factors such as external force, and the sample positioning effect needs to be improved. Based on this, the utility model provides a sample positioning device for a metallographic microscope. Utility Model Content

[0004] The technical problem solved by the utility model is that the sample cannot be firmly and stably pressed between the tablet pressing clamp and the stage plate, which may easily cause the position of the sample to shift due to external factors such as external force, and the sample positioning effect needs to be improved.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a metallographic microscope sample positioning device, including a support plate, a stage plate is provided at the top center of the support plate, a plurality of clamping assemblies are provided on the top circumference of the support plate and are placed around the stage plate, the clamping assembly includes an L-shaped plate, a screw is threadedly connected to the top of the L-shaped plate, a slide plate is rotatably connected to the inner wall of the L-shaped plate at the bottom of the screw, and a clamping plate is rotatably connected to the bottom of the slide plate and is placed above the stage plate.

[0006] Furthermore, the clamping assemblies are provided in three numbers and are distributed around the stage plate in a regular triangle structure.

[0007] Furthermore, the L-shaped plate is arranged on the outside of the stage plate, and a handle is provided on the top of the screw rod and is placed on the outside of the L-shaped plate.

[0008] Furthermore, the inner side wall of the L-shaped plate is symmetrically provided with slide rails matching the side walls of the slide plate.

[0009] Furthermore, a buffer pad is provided at the bottom of the pressing plate.

[0010] Furthermore, a rotating rod is provided at the bottom of the screw rod, and the rotating rod is rotatably connected to the top of the slide plate via a bearing.

[0011] Beneficial effects of the utility model:

[0012] By holding the clamping assembly and rotating the handle, the screw is driven to rotate and move up and down, which in turn drives the slide to move up and down, which in turn drives the clamping plate to move up and down, so that the sample can be clamped and positioned between the clamping plate and the stage. Compared with the traditional use of a compression clamp, it can firmly and stably clamp and position samples of different sizes between the clamping plate and the stage as needed, effectively avoiding the situation where the position of the sample is offset due to external factors such as external force, and the sample positioning effect is greatly improved.

Compared with the traditional use of a compression clamp, samples of different sizes can be firmly and stably compressed and positioned between the clamping plate 7 and the stage plate 2 as needed, effectively avoiding the situation where the sample position is offset due to external factors such as external force when using a metallographic microscope for observation, and the sample positioning effect is greatly improved.

[0025] Principle of the utility model

[0026] When using a metallographic microscope to observe the sample, when there is no need to use the clamping assembly 3 to clamp the sample, it is only necessary to rotate the clamping plate 7 to the outside of the stage plate 2. When the clamping assembly 3 needs to be used to clamp the sample, by holding the handle 8 and rotating it, the screw 5 is driven to rotate and move up and down, thereby driving the slide plate 6 to move up and down, and then the clamping plate 7 can be driven to move up and down, so that the sample can be clamped and positioned between the clamping plate 7 and the stage plate 2. Compared with the traditional use of a compression clamp, samples of different sizes can be firmly and stably clamped and positioned between the clamping plate 7 and the stage plate 2 as needed, effectively avoiding the situation where the position of the sample is offset due to external factors such as external force, and the sample positioning effect is greatly improved.
