Description

Technical Field

[0001] This utility model relates to the field of testing and analysis equipment technology, specifically a device for fixing the fracture surface of a filament-like sample for scanning electron microscopy. Background Technology

[0002] In the steel industry, examining the fracture surfaces of filamentous samples (such as steel wire and wire rod) is a crucial step in material performance analysis and quality control. The fracture surface examination of filamentous samples serves as a bridge connecting macroscopic properties and microscopic mechanisms. By analyzing fracture characteristics, material or process defects can be quickly diagnosed, guiding production improvements, preventing failures, and ensuring the reliability of steel products under harsh operating conditions.

[0003] However, when examining the fracture surface of filamentous samples, the small cross-section of the sample makes it difficult to securely and properly position it on the scanning electron microscope stage. Current techniques involve using conductive adhesive to fix the sample to a pre-prepared block sample. However, this process is prone to sample detachment or insecure fixation, severely impacting analytical efficiency and jeopardizing equipment safety if the sample detaches. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a device for fixing the fracture surface of a filamentous sample for scanning electron microscope, which can firmly clamp and fix the filamentous sample, prevent the sample from falling off, and thus improve the analysis efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for fixing the fracture surface of a filamentous sample for scanning electron microscopy includes an upper base plate, a lower base plate, an adjusting plate, and a clamping plate. The upper base plate consists of an upper horizontal plate and an upper vertical plate fixed to the bottom of one side of the upper horizontal plate. The lower base plate consists of a lower horizontal plate and a lower vertical plate fixed to the top of one side of the lower horizontal plate. The upper vertical plate, the lower vertical plate, and the adjusting plate are connected by bolts. The adjusting plate has a vertical elongated hole to adjust the overall height of the device. The upper horizontal plate has multiple sample holes, and the lower horizontal plate has a fixing plate. The filamentous sample is placed in the sample hole, and the bottom of the filamentous sample is placed between the fixing plate and the clamping plate. The fixing plate and the clamping plate are connected by bolts to clamp and fix the filamentous sample.

[0007] Furthermore, the sample holes are arranged in two rows, symmetrically on the upper horizontal plate, with diameters corresponding to the filamentous sample.

[0008] Furthermore, the fixing plate is disposed on both sides of the lower horizontal plate of the lower seat plate and is fixedly connected to the top surface of the lower horizontal plate.

[0009] Furthermore, the adjustment plate is a rectangular flat plate.
