Technical Field

[0002] Polishing and sample preparation are crucial process links in the fields of metal processing, semiconductor manufacturing, optical components, etc. In X-ray diffraction (hereinafter referred to as XRD) experiments, the samples to be tested must first be cut, ground, polished, etc. to make them into a shape suitable for XRD analysis. For bar samples, they usually need to be ground into a plane or cylinder for XRD experiments. During the processing, a clamp is usually required to clamp the sample, which can improve the control over the sample and make the grinding and polishing process simpler and more convenient. However, the clamps currently on the market can only fix the size for sample preparation. However, due to the small size of amorphous and high-entropy samples, they are often difficult to fix, making grinding and polishing more difficult. They are basically inlaid, but the inlay materials required for inlay are expensive and time-consuming. Utility Model Content

[0030] The clamping jaw 2 described in this embodiment is slidably connected to the connecting tube 1 and is threadedly connected to the adjusting ring 3. By rotating the adjusting ring 3, the clamping jaw 2 slides relative to the connecting tube 1, so that the ends of the clamping jaw 2 are close to or separated from each other, thereby realizing stepless adjustment of the clamping jaw 2, so that the clamping jaw 2 can clamp amorphous samples of different types, shapes and sizes, which is beneficial to improving the application range of the clamping jaw 2; in addition, the clamping jaw 2 is threadedly connected to the adjusting ring 3, which can increase the clamping force of the clamping jaw 2 on the amorphous sample, make the clamp clamp the amorphous sample more firmly and stably, and the operator can punch the amorphous sample more accurately.

[0031] like Figure 3As shown, in this embodiment, the outer circumference of the connecting tube 1 is provided with an annular groove 12, the inner circumference of the adjusting ring 3 is embedded in the annular groove 12 and is rotatably connected to the annular groove 12, the inner side wall of the adjusting ring 3 is provided with an internal thread 31, and the outer side of the clamping jaw 2 is provided with an external thread 22 matching the internal thread 31, and the external thread 22 is exposed in the annular groove 12 and is threadedly connected to the internal thread 31, and the annular groove 12 can form an axial limit for the adjusting ring 3, so that the rotation of the adjusting ring 3 can be effectively converted into the sliding of the clamping jaw 2, making the adjustment of the clamping jaw 2 by the adjusting ring 3 smoother.
[0032] like Figure 2 In the present embodiment, the connecting tube 1 is provided with three sliding holes 13 for the sliding of the clamping jaws 2, and the corresponding connecting tube 1 is slidably connected with three clamping jaws 2, the sliding holes 13 are uniformly distributed on the outer peripheral side of the through hole 11 in the circumferential direction, the sliding holes 13 pass through the annular groove 12 and are partially in the annular groove 12, the sliding holes 13 are inclined relative to the through hole 11, and the end of the sliding hole 13 close to the connecting tube 1 is closer to the through hole 11, the connecting tube 1 has a first central axis 14, the sliding hole 13 has a second central axis 131, and all the second central axes 131 are The first central axis 14 intersects at the same point, and the external thread 22 of the clamp can be directly threadedly connected with the internal thread 31 of the adjustment ring 3 through the sliding hole 13, which is conducive to improving the connection stability between the clamp 2 and the adjustment ring 3. In addition, the sliding hole 13 can make the ends of the clamp 2 converge at the same point, which is conducive to improving the clamping force of the clamp 2, making the clamp 2 clamp the amorphous sample more firmly and reliably. At the same time, when the clamp 2 clamps the amorphous sample, the force on the amorphous sample is more uniform, reducing the possibility of the amorphous sample breaking. It should be noted that in other embodiments, the connecting tube 1 can also be 2 clamps 2 or the number of clamps 2 is greater than 3.
[0033] In order to increase the clamping force of the jaws 2 on the amorphous sample, the opposite side surface of the jaws 2 in this embodiment is provided with anti-slip grooves 23. The anti-slip grooves 23 can increase the friction of the jaws 2 on the amorphous sample, thereby improving the positioning stability of the amorphous sample and making the fixation of the amorphous sample more firm and reliable.
[0034] In this embodiment, the outer peripheral side of the connecting tube 1 is provided with a connecting sleeve 32, and the connecting sleeve 32 is fixedly connected to the adjusting ring 3. The connecting sleeve 32 rotates and drives the adjusting ring 3 to rotate. The connecting sleeve 32 can increase the axial width of the adjusting ring 3, thereby increasing the gripping area of the adjusting ring 3, making the adjustment of the adjusting ring 3 more convenient and labor-saving.
[0035] like Figure 4As shown, the adjusting member 41 in this embodiment includes a connecting portion 412 and an operating portion 411. The operating portion 411 extends into the through hole 11 and is threadedly connected to the through hole 11. The operating portion 411 and the connecting portion 412 are an integrated structure.

[0036] like Figure 5 As shown, the clamp in this embodiment further includes a hand-held sleeve 5 and an end cap 52. The hand-held sleeve 5 is provided with a receiving cavity 51 for receiving the connecting tube 1. One end of the hand-held sleeve 5 is provided with a through hole 531 for the amorphous sample to pass through, and the other end is threadedly connected with the end cap 52. The end cap 52 is provided with a positioning rib 521 extending into the receiving cavity 51 and used to position the connecting tube 1. When the connecting tube 1 is placed in the receiving cavity 51, the end cap 52 is connected to the end of the hand-held sleeve 5, and the end cap 52 is tightened so that the positioning rib 521 gradually extends into the receiving cavity 51. 1 and counteract with the counterweight block 42, the hand-held sleeve 5 can increase the holding area of the operator, making it more convenient and labor-saving for the operator to hold the clamp, which is beneficial to improving the operator's control ability of the clamp, and thus improving the sample preparation effect; in addition, the positioning rib 521 can position the connecting tube 1 in the hand-held sleeve 5, reduce the shaking amplitude of the connecting tube 1, and thus maintain the stability of the amorphous sample, and the operator can grind and polish the amorphous sample more accurately, so as to obtain a more accurate amorphous sample.

The wear-resistant ring 53 can protect the clamping jaw 2 to prevent the clamping jaw from directly contacting the grinding tool, thereby reducing the possibility of the clamping jaw 2 being worn, which is beneficial to increasing the service life of the clamping jaw 2.
[0038] The application process of this embodiment is as follows:
[0039] By rotating the adjusting ring 3, the clamping jaws 2 slide upward along the sliding hole 13, so that the distance between the ends of the clamping jaws 2 is increased, so that the amorphous sample can penetrate into the clamping area 21. Then, the adjusting ring 3 is rotated in the opposite direction to drive the clamping jaws 2 to slide downward along the sliding hole 13, so that the distance between the ends of the clamping jaws 2 becomes smaller, thereby achieving the clamping of the amorphous sample. Then, the adjusting member 41 is rotated to drive the loading rod 4 to slide downward along the through hole 11 until the end of the loading rod 4 abuts against the end of the amorphous sample. Then, according to the size and size of the amorphous sample, a suitable pressure is selected to assemble a corresponding number of counterweights 42 at the end of the loading rod 4, thereby improving the overall weight and stability of the clamp. Then, the connecting tube 1 is placed in the accommodating cavity 51 of the hand-held sleeve 5, and the amorphous sample is passed through the through hole 531. The end cover 52 is installed at the rear end of the hand-held sleeve 5, and the end cover 52 is tightened so that the positioning rib 521 gradually extends into the accommodating cavity 51 until the positioning rib 521 abuts against the counterweight 42, thereby achieving the clamping of the amorphous sample.
