[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] A sample preparation device for material failure cross-section testing includes a worktable 101. A lifting mechanism 4 is installed at the bottom of the worktable 101. A through groove is formed in the middle of the worktable 101, and a clamping mechanism 2 is installed on the through groove. A fixing groove 305 is formed inside the worktable 101, and the fixing groove 305 communicates with the through groove. A shearing mechanism 3 is installed inside the fixing groove 305. The clamping mechanism 2 includes a lower fixing sleeve 202 fixedly installed at the middle of the bottom end of the worktable 101, and an upper fixing sleeve 201 installed at the top of the worktable 101. Clamping plates 203 are symmetrically arranged on both sides inside the lower fixing sleeve 202. A sliding column 205, one end of which penetrates the middle of the lower fixing sleeve 202, is installed on the middle of the outer side of each clamping plate 203. A limit plate 206 is installed on the other end of the sliding column 205. A connecting spring 204 is sleeved on the outside of the sliding column 205. The connecting spring 204 is fixedly installed on both sides inside the lower fixing sleeve 202 and on the clamping plates 203, respectively. During the process, when the operator uses the material, first, keep it perpendicular to the workbench 101. Then, the operator only needs to pull the limiting plates 206 on both sides away from the lower fixed sleeve 202, thereby driving the clamping plate 203 closer to the lower fixed sleeve 202. In this state, the connecting spring 204 gradually returns from its original state to a state of contraction. Then, the material passes through the middle of the upper fixed sleeve 201, the middle of the workbench 101, and the middle of the lower fixed sleeve 202. At this time, the bottom of the material is located under the bottom surface of the workbench 101. After the inspector adjusts the material to the position to be cut, the inspector only needs to release the limiting plates 206, so that the connecting spring 204 gradually returns from the state of contraction to its original state. At the same time, the clamping plate 203 is tightly attached to the surface of the material, thereby stably clamping the material on the workbench 101, so that the inspector can cut the failed section later.

[0028] The upper fixed sleeve 201 and the lower fixed sleeve 202 are interconnected in the middle and are also interconnected with the through slots opened on the worktable 101. In this embodiment, the upper fixed sleeve 201, the lower fixed sleeve 202 and the worktable 101 are interconnected, which is conducive to the material being able to pass through the upper fixed sleeve 201, the lower fixed sleeve 202 and the worktable 101 in sequence, so as to facilitate the clamping and fixing of the material by the testing personnel in the later stage.

[0029] The shearing mechanism 3 includes a threaded rod 302 installed inside a fixed groove 305. The threaded rod 302 passes through one side of the worktable 101 and is connected to a motor 301 installed on the worktable 101. A cutting blade 303 slides on the threaded rod 302, and a fixed guide post 304 slides on the side of the cutting blade 303 away from the threaded rod 302. In this embodiment, after the inspector clamps and fixes the material, the motor 301 is then driven, causing the motor 301 to rotate the threaded rod 302. Simultaneously, when the threaded rod 302 rotates, it drives the cutting blade 304 to rotate. The cutting blade 303 slides, and under the action of the fixed guide post 304 on the other side of the cutting blade 303, the cutting blade 303 can move stably so that it can cut the material. This allows the inspectors to further inspect the failed section of the material. At the same time, under the action of the upper fixed sleeve 201, the cutting blade 303 can avoid the splashing of chips when cutting the material. After the cutting is completed, it is easy for the inspectors to collect the chips, thus avoiding the waste of material.

[0030] The fixed guide post 304 and the threaded rod 302 are parallel to each other, and a through groove is provided between the fixed guide post 304 and the threaded rod 302. In this embodiment, the fixed guide post 304 and the threaded rod 302 are parallel, which helps to keep the cutting end face of the cutting blade 303 parallel to the fixed guide post 304 at all times, thereby improving its cutting effect. The through groove is provided between the fixed guide post 304 and the threaded rod 302, so that the cutting blade 303 can completely cut the material.

[0031] The lifting mechanism 4 includes connecting columns 401 installed at the four corners of the bottom of the worktable 101. A movable column 402 slides on the bottom of the connecting column 401. A universal wheel 407 is installed on the bottom of the movable column 402. A fixing spring 403 is sleeved on the outside of the movable column 402. The two ends of the fixing spring 403 are respectively installed on the connecting column 401 and the universal wheel 407. A fixing component is provided at one end of the connecting column 401. In this embodiment, since some materials are relatively inconvenient to transport over long distances, the inspection personnel only need to move the entire device to the required position under the action of the universal wheel 407. At the same time, under the action of the fixing spring 403, the connecting column 401 and the movable column 402 can always maintain relative stability.

[0032] The fixing assembly includes a pull rod 404 extending through one side of the connecting post 401, and the pull rod 404 is inserted into a fixing hole at the top of the movable post 402. A movable handle 405 is installed on the side of the pull rod 404 away from the connecting post 401. A limiting spring 406 is sleeved on the outside of the pull rod 404, and the two ends of the limiting spring 406 are respectively installed on the connecting post 401 and the movable handle 405. In this embodiment, due to the different relative heights of the materials being cut, when the inspector needs to cut the top of the relatively higher material, the operator only needs to pull the movable handle 405 in the direction away from the connecting post 401, thereby moving the pull rod 404 accordingly, and simultaneously causing the limiting spring 405 to move away from the connecting post 401. 6. Gradually return from the original state to the state of contraction under force. At this time, simply move the caster 407 and the moving column 402 together away from the connecting column 401. At this time, the fixing spring 403 gradually returns from the original state to the state of extension under force. When the desired height is reached, the operator releases the moving handle 405, so that the limit spring 406 gradually returns from the state of extension under force to the original state. At the same time, the pull rod 404 passes through the connecting column 401 and is inserted into the moving column 402, so that the height between the connecting column 401 and the moving column 402 is fixed. This allows the device to cut different materials, which helps to improve the practicality of the device.

[0033] The movable column 402 has multiple fixing holes equidistantly spaced in the vertical direction on the side away from the movable handle 405, for inserting the pull rod 404. In this embodiment, the setting of multiple fixing holes makes it convenient for the testing personnel to fix the overall height of the connecting column 401 and the movable column 402 after adjustment.

[0034] The working principle of this utility model is as follows: When using it, the operator first keeps the material perpendicular to the workbench 101. Then, the operator simply pulls the limiting plates 206 on both sides away from the lower fixed sleeve 202, thereby causing the clamping plate 203 to move closer to the lower fixed sleeve 202. In this state, the connecting spring 204 gradually returns from its original state to a contracted state, allowing the material to pass through the middle of the upper fixed sleeve 201, the middle of the workbench 101, and the middle of the lower fixed sleeve 202. At this point, the bottom of the material is positioned below the bottom surface of the workbench 101. After the inspector adjusts the material to the desired cutting position, the inspection... At this point, the operator only needs to loosen the limiting plate 206, allowing the connecting spring 204 to gradually return from its contracted state to its original state. Simultaneously, the clamping plate 203 is brought into close contact with the material surface, thus stably clamping the material onto the worktable 101. This facilitates subsequent cutting of the failed section by the inspection personnel. After the inspection personnel have clamped and fixed the material, the motor 301 is then driven, causing the threaded rod 302 to rotate. Simultaneously, as the threaded rod 302 rotates, the cutting blade 303 slides. Under the action of the fixed guide post 304 on the other side of the cutting blade 303, the cutting blade 303 can move stably, enabling cutting. The blade 303 can cut the material, facilitating further inspection of the failed cross-section by the inspector. Simultaneously, the upper fixing sleeve 201 prevents the blade 303 from scattering debris during cutting, allowing for easy collection of debris after cutting and preventing material waste. Since the relative height of the material varies, when the inspector needs to cut the top of a relatively high piece of material, the operator simply pulls the moving handle 405 away from the connecting post 401, causing the pull rod 404 to move accordingly, and simultaneously releasing the limit spring 406. The device gradually returns to its contracted state from its original state. At this point, simply move the caster 407 and the moving column 402 together away from the connecting column 401. The fixing spring 403 then gradually returns to its extended state from its original state. When the desired height is reached, the operator releases the moving handle 405, causing the limit spring 406 to gradually return to its original state from its extended state. Simultaneously, the pull rod 404 passes through the connecting column 401 and is inserted into the moving column 402, thus fixing the height between the connecting column 401 and the moving column 402. This allows the device to cut different materials, improving its practicality.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
