Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing machine technology, specifically a low-cost vibration polishing machine for preparing electron backscatter diffraction samples. Background Technology
[0002] In certain scientific research, electron backscatter diffraction (EBSD) technology is often used to characterize the microstructure of materials. EBSD samples require the observation surface to have a mirror effect and a small stress layer. Traditional mechanical polishing and electrolytic polishing methods are not very effective for preparing multiphase materials that have undergone large plastic deformation. Therefore, vibration polishing is often used to obtain high-quality EBSD samples.
[0003] In the current market, traditional vibratory polishing machines are expensive (commercially available at 30,000 to 120,000 RMB), with the cost of preparing a single sample reaching as high as 500 RMB. Therefore, improvements to existing equipment are necessary. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] like Figure 1-6 As shown, this utility model provides a technical solution: a low-cost vibration polishing machine for preparing electron backscatter diffraction samples, including a vibration plate base 1, a flat-bottomed fixed disc 2, and a sample holder 3. The vibration plate base 1 has a screw hole 4 on its top. The flat-bottomed fixed disc 2 has a through hole 5. The flat-bottomed fixed disc 2 is inserted into the screw hole 4 through the through hole 5 by a screw, and is connected and tightened after rotation. A stud 6 is fixedly connected to the top of the flat-bottomed fixed disc 2. A flat-bottomed stainless steel disc 7 is placed above the flat-bottomed fixed disc 2. A through hole 8 is opened on the flat-bottomed stainless steel disc 7. The through hole 8 on the flat-bottomed stainless steel disc 7 is inserted into the stud 6, and then a nut is used to fix it to the flat-bottomed fixed disc 2. A metallographic polishing cloth 9 is laid on the flat-bottomed stainless steel disc 7. A water-blocking ring 10 is installed on the inner wall of the flat-bottomed stainless steel disc 7. The sample holder 3 is placed on the metallographic polishing cloth 9. Polishing liquid is poured into the flat-bottomed stainless steel disc 7.
[0026] Furthermore, the bottom of the vibratory plate base 1 is provided with a horizontal adjustment pad 11, which can adjust the vibratory plate base 1 to be horizontal, ensuring that the sample holder 3 makes uniform circular motion in the horizontal flat-bottomed stainless steel disc 7.
[0027] Furthermore, the dimensions and positions of the through hole 5 and the screw hole 4 are matched to ensure that the flat-bottomed fixed disc 2 is firmly connected to the vibratory plate base 1.
[0028] Furthermore, the position and size of the through hole 8 are matched with the position and size of the stud 6 to ensure that the flat-bottomed stainless steel disc 7 is firmly connected to the flat-bottomed fixed disc 2 and will not affect the polishing quality.
[0029] Furthermore, the top of the sample holder 3 is equipped with a knurled hand-tightening round nut 12, which can be rotated upwards to facilitate adjustment of the configuration of the sample holder 3 and ensure that the sample is in close contact with the polishing cloth.
[0030] Furthermore, the vibratory plate base 1 can drive the sample holder 3 to move in a uniform circular motion on the flat-bottomed stainless steel disc 7, ensuring that the sample surface is fully polished and an electron backscattering sample with almost no stress layer on the surface is obtained.
[0031] Furthermore, a power cord 13 is provided on the side wall of the vibratory feeder base 1, which is connected to an external vibratory feeder controller and power supply to ensure normal start-up and control of the device.
[0032] In summary, the workflow of this utility model is as follows: First, place the vibratory plate base 1 stably and adjust the leveling pads 11 at its bottom to keep the vibratory plate base 1 level. Pick up the flat-bottomed fixed disc 2 and align the through hole 5 with the screw hole 4. Fix the flat-bottomed fixed disc 2 to the vibratory plate base 1 with bolts. Then pick up the flat-bottomed stainless steel disc 7 and fit the through hole 8 onto the stud 6 on the flat-bottomed fixed base 2. Fix it with nuts. Lay the metallographic polishing cloth 9 on the flat-bottomed stainless steel disc 7. Install the water-blocking ring 10 on its side wall and pour in the polishing liquid. Then use the sample holder 3 to fix the electron backscattering sample and place it on the metallographic polishing cloth 9. Connect the power cord 13 and start the device. The sample holder 3 will make uniform circular motion inside the flat-bottomed stainless steel disc 7 to obtain an electron backscattering sample with almost no stress layer on the surface.
