Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy production technology, specifically to a micro sample holder for an inverted microscope used for microstructure analysis of aluminum alloys. Background Technology
[0002] Aluminum alloys, as an important metallic material, are widely used in aerospace, automotive manufacturing, mechanical engineering, and many other fields due to their excellent properties such as light weight, high strength, corrosion resistance, and ease of processing. With the continuous improvement of the performance requirements of modern industry for aluminum alloys, in-depth research on the microstructure of aluminum alloys is crucial for optimizing their performance and developing new aluminum alloy materials. By observing the microstructure of aluminum alloys, such as grain size, shape, distribution, and the precipitation of the second phase, we can gain a deeper understanding of the relationship between their internal structure and performance, thereby providing a scientific basis for the composition design and processing technology optimization of aluminum alloys. In the study of the microstructure of aluminum alloys, the inverted microscope is a commonly used and important tool. It can provide high-resolution microscopic images, helping researchers to clearly observe the microstructural features of aluminum alloys. When using an inverted microscope, it is only necessary to invert the sample on the stage, with the test surface of the sample facing the light aperture. However, due to product shape limitations, samples such as thin profiles, plates, and wires are often in the form of thin sheets or thin rods. Thin sheet samples are difficult to invert on the stage, and they are prone to tipping over when the stage is moved. Thin rod samples are usually... The sample is smaller than the light aperture of the stage, making it impossible to place it upside down on the stage. For a large number of sheet-like or rod-like microstructure samples, the usual practice is to place a large object on the light aperture of the stage, leaving part of the light aperture open, so that the sheet-like or rod-like sample can rest against the object to place the sample on the stage and complete the subsequent test. However, this method has many problems, such as difficulty in placing the sample upright, the sample is easy to tip over, the test surface of the upright sample is not level, which makes observation inconvenient, and the fact that the rod-like sample needs a support point, making it impossible to observe the entire cross section at once. Utility Model Content
[0003] This invention provides a micro sample holder for an inverted microscope for aluminum alloy microstructure analysis, in order to solve the problems mentioned above.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A micro sample holder for an inverted microscope for aluminum alloy microstructure includes parallel sliding rods. Both sides of the sliding rods are detachably connected to baffles. A left slider and a right slider are movably sleeved on the sliding rod between the baffles. Springs are sleeved on the sliding rod between the left slider and the baffles, and between the right slider and the baffles. A semi-circular through hole is also provided on the side of the right slider closer to the left slider.
[0006] Furthermore, the baffle and the slide bar are connected by a locking nut.
[0007] This utility model has the following beneficial effects:
[0008] This utility model features a compact and lightweight design, simple structure, and convenient operation. Based on the spring clamping principle, the clamp can stably hold small aluminum alloy microstructure samples. It is especially suitable for clamping thin sheet and rod-shaped aluminum alloy samples made of thin profiles, plates, and wires. In use, the entire clamp is placed on the microscope stage, which effectively solves the problem of the difficulty in placing thin sheet and rod-shaped aluminum alloy microstructure samples on the inverted microscope stage, greatly reducing the difficulty of experimental operation and improving the overall efficiency of the experiment.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0013] like Figure 1 As shown, a micro sample holder for an inverted microscope for aluminum alloy microstructure includes two parallel sliding rods 1. Both sides of the sliding rods 1 are detachably connected to baffles 5. A left slider 2 and a right slider 3 are movably sleeved on the sliding rods 1 between the baffles 5. Springs 6 are sleeved on the sliding rods 1 between the left slider 2 and the baffles 5, and between the right slider 3 and the baffles 5. A semi-circular through hole 4 is also opened on the side of the right slider 3 near the left slider 2.
[0014] The baffle 5 and the slide rod 1 are connected by a locking nut 7.
[0015] This clamp consists of a sliding rod 1, a clamp frame, a left slider 2, and a right slider 3. The left slider 2 and right slider 3 are fitted onto the sliding rod 1, and under the action of a spring 6 on the sliding rod 1, the left slider 2 and right slider 3 form a clamping device. The clamp frame is a rectangular frame composed of two 80mm sliding rods 1 and two 60mm baffles 5 at both ends of the sliding rods 1. The diameter of the two ends of the two sliding rods 1 is 3.5mm, which is 5mm smaller than the diameter of the rod body, and they are threaded for the installation and fixation of the baffles 5. The sliding rods 1 are smooth, facilitating the left and right sliding of the left slider 2 and right slider 3. The two baffles 5 are 1mm thick and 10mm high, with holes at both ends, each 4mm in diameter, larger than the diameter of the ends of the sliding rods 1 but smaller than the diameter of the rod body. They are fitted onto the ends of the two sliding rods 1 through these holes and secured with... The nuts are fixed in place. Each slide rod 1 is equipped with two springs 6 for clamping and supporting the left slide rod 2 and the right slide rod 3. Both the left slide rod 2 and the right slide rod 3 are rectangular structures with holes at both ends. The hole diameter is 5.5mm, which is larger than the diameter of the slide rod 1. The holes are fitted between the two slide rods 1. The left slide rod 2 and the right slide rod 3 are pressed against the baffle 5 by the springs 6, so that the left slide rod 2 and the right slide rod 3 are close together. The middle of the two slide rods is used to clamp the sample. The right slide rod 3 has a semi-circular through hole 4 with a diameter of 5mm in the center on the left side, which is convenient for clamping thin rod-shaped samples.
[0016] In practical application, the fixture is placed on a clean, smooth surface. The left slider 2 and right slider 3 are pulled apart by hand, and the prepared sheet-like sample is placed between the left slider 2 and right slider 3. The side of the thin rod-shaped sample is placed between the sliders near the semi-circular through hole 4, with the sample face down, naturally perpendicular to the smooth surface. Then, the left slider 2 and right slider 3 are released, and the left slider 2 and right slider 3 move closer together under the action of the two springs 6, completing the clamping of the sample. The entire fixture is then placed on the microscope stage, with the sample face aligned with the microscope's light aperture. The sample is observed using the microscope. After the experiment, the entire fixture is removed, the left slider 2 and right slider 3 are separated, and the sample is removed, restoring the fixture to its original state. This completes the entire sample clamping process, effectively solving the problem of difficulty in placing sheet-like and thin rod-shaped aluminum alloy microstructure samples on an inverted microscope stage. It greatly reduces the difficulty of experimental operation and improves the overall efficiency of the experiment. Therefore, this fixture has good practicality.
