[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0019] like Figures 1 to 3 As shown, this utility model discloses a metallographic sample polishing machine for easy fixation, comprising an operating table 1 and a polishing disc 2. The operating table 1 has a polishing groove on its top, and the polishing disc 2 is mounted in the polishing groove. It also includes a fixing plate 3, two sets of connecting plates 4, two sets of clamping plates 5, a first adjustment component, and a lifting mechanism. The top rear end of the operating table 1 is connected to the bottom of the fixing plate 3. The front end of the fixing plate 3 slides tightly against the rear ends of the two connecting plates 4 via the first adjustment component. The front sides of the two sets of connecting plates 4 are respectively connected to one end of the clamping plate 5 via the lifting mechanism. The sample is placed between the two sets of clamping plates. The distance between the connecting plates is adjusted using the first adjustment component to accommodate the sample width. The height of the clamping plates is then adjusted using the lifting mechanism to align the sample with the polishing disc and ensure it is tightly fitted. After clamping, the polishing disc is activated for polishing. This device can quickly clamp and position samples of different sizes and shapes, and is compatible with various sample specifications, allowing for quick clamping and fixation of samples of different specifications, thus improving the convenience and practicality of the device.
[0020] As a preferred embodiment of the above, the first adjustment component includes a bidirectional screw 6 and two sets of first sliders 7. The front end of the fixed plate 3 is provided with a sliding groove. Both ends of the bidirectional screw 6 are rotatably connected to one end of the sliding groove, and the two sets of first sliders 7 are threadedly connected to one outer end of the bidirectional screw 6. The front ends of the two sets of first sliders 7 are respectively connected to the rear end of a set of connecting plates 4. The bidirectional screw is driven to rotate, and the two sets of first sliders move in opposite directions along the sliding groove of the fixed plate, thereby adjusting the distance between the two sets of connecting plates. According to the sample width, the connecting plates are adjusted to a suitable position and then the rotation stops, realizing the synchronous reverse movement of the two sets of connecting plates. The adjustment efficiency is high and the spacing is symmetrical, which can adapt to samples of different widths. In addition, the threaded drive has a self-locking function. After the adjustment is completed, the position of the connecting plates is stable and no additional locking device is required, thus enhancing practicality.
[0021] As a preferred embodiment of the above, the lifting mechanism includes two sets of connecting blocks 8, two sets of mounting blocks 9, two sets of second sliders 10, a second adjustment component, and a connecting component. Each of the two sets of connecting plates 4 is provided with a set of sliding holes. The two sets of connecting blocks 8 are slidably connected to the sliding holes of the connecting plates 4. One end of each of the two sets of connecting blocks 8 is connected to one end of a set of mounting blocks 9, and the other end of each of the two sets of mounting blocks 9 is connected to one end of a set of clamping plates 5. The other end of each of the two sets of connecting blocks 8 is connected to one end of a set of second sliders 10. Each of the two sets of second sliders 10 is provided with a second adjustment component. According to the sample thickness or polishing position requirements, the clamping plate is adjusted to a suitable height using the second adjustment component and then rotation stops. Precise fine-tuning of the clamping plate height is achieved through threaded transmission, adapting to the polishing requirements of samples of different thicknesses, thus enhancing practicality.
[0022] As a preferred embodiment of the above, the connecting assembly includes two sets of positioning plates 11, two sets of first locking blocks 12, and two sets of positioning screws 13. Each of the two sets of mounting blocks 9 has a set of slots at one end. One end of each of the two sets of first locking blocks 12 engages with a slot in the mounting block 9, and one end of each of the two sets of positioning plates 11 connects to the other end of each of the first locking blocks 12. Each of the two sets of first locking blocks 12 has a set of threaded holes that are observably provided with the corresponding slot in the mounting block 9. The bottoms of the two sets of positioning screws 13 are threadedly connected to the first locking blocks 12 and their corresponding slots through the threaded holes. When the first locking block is engaged in the mounting block slot, the positioning screw is rotated through the threaded hole and tightened to fix the positioning plate to the mounting block. During disassembly, the positioning screw is rotated in the opposite direction to separate the first locking block from the slot, allowing for quick replacement of the clamping plate to adapt to different clamping requirements, thus enhancing practicality.
[0023] As a preferred embodiment of the above, the second adjustment component includes four sets of fixing blocks 14 and two sets of first screws 15. A set of fixing blocks 14 is respectively provided at the top and bottom of one end of each of the two sets of connecting plates 4. A set of pre-drilled holes is provided at the top of each of the two sets of fixing blocks 14. The top outer sides of the two sets of first screws 15 are rotatably connected to the pre-drilled holes of the fixing blocks 14, and the bottom of the two sets of first screws 15 are rotatably connected to the top of the fixing blocks 14 at the other end. Each of the two sets of second sliders 10 is provided with a set of threaded holes, and each set of second sliders 10 is threadedly connected to a set of threaded holes. This causes the first screws to rotate, and the second sliders to move up and down along the threads of the first screws, adjusting the height of the connecting blocks and the clamping plates. This allows workers to quickly adjust the height, thus enhancing practicality.
[0024] As a preferred embodiment of the above, it also includes a first handle 16, with the left end of the bidirectional screw 6 passing through the corresponding slide groove and connecting to the right end of the first handle 16; this provides a force-saving point of application, reduces operational fatigue, and thus enhances practicality.
[0025] As a preferred embodiment of the above, it also includes four sets of second handles 17, with the tops of two sets of first screws 15 and two sets of positioning screws 13 respectively connected to the bottom of one set of second handles 17; providing a force-saving point of application, reducing operational fatigue, and thus enhancing practicality.
[0026] As a preferred embodiment of the above, it also includes two sets of anti-slip pads 18, with one set of anti-slip pads 18 respectively provided at one end of each of the two sets of clamping plates 5; this prevents the sample from sliding due to the lateral force generated by the rotation of the polishing disc during the polishing process, and is especially suitable for samples with smooth or irregular surfaces, thereby improving the clamping reliability and thus enhancing practicality.
[0027] This utility model discloses a metallographic sample polishing machine that facilitates fixation. Its working principle is as follows: Based on the sample width, the first handle drives the bidirectional screw, and the first slider adjusts the distance between the two sets of connecting plates so that the distance between the clamping plates is slightly greater than the sample width. The sample is then placed between the two sets of clamping plates. The bidirectional screw and the first screw are then finely adjusted again to ensure the clamping plates are tightly fitted to both sides of the sample. Next, based on the sample thickness, the second handle drives the first screw, and the second slider adjusts the height of the connecting block and the clamping plates, ensuring that the bottom of the sample and the top of the polishing disc are tightly fitted. The polishing disc is then started, and the polishing pressure and speed are adjusted to polish the sample. During the polishing process, the sample clamping status is observed to ensure there is no displacement or shaking until polishing is complete.

[0030] The above description is only a preferred embodiment. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the preferred technical principle, and these improvements and modifications should also be considered within the scope of protection of the preferred embodiment.
