[0002] High-speed steel, a special type of steel that combines high hardness, wear resistance, and heat resistance, is widely used in the manufacturing of precision cutting tools, molds, and high-end mechanical components. In the high-speed steel machining process, surface polishing is a crucial step that determines the workpiece's precision and lifespan. Its core purpose is to remove surface machining marks, burrs, and oxide layers to achieve a high-precision surface finish.

[0003] Currently, when polishing high-speed steel workpieces, the switching of sandpaper grit in the polishing mechanism mostly relies on manual operation. In scenarios requiring multiple polishing processes, frequent replacement of polishing components is not only time-consuming and labor-intensive, but may also lead to quality problems such as surface scratches and over-polishing due to human error. Therefore, a surface polishing device for high-speed steel processing is proposed. Utility Model Content

[0026] In this embodiment, by placing the high-speed steel workpiece 13 on the placement table 17, the second motor 18 drives the second screw 19 to rotate, causing the second drive block 110 to slide along the guide rod 111, driving the clamp 112 to move and clamp the workpiece. During polishing, the first motor 12 drives the first screw 13 to rotate, driving the first drive block 14 and drive plate 15 to move along the first slide rail 16, causing the placement table 17 to move towards the other end of the polishing table 11.

[0028] In this embodiment, the cylinder 22 pushes the mounting bracket 23 down along the second slide rail 24, so that the polishing sandpaper 28 contacts the workpiece. The third motor 25 drives the rotating shaft 26 to rotate, and the polishing pressure is transmitted through the buffer rubber layer 27. Multiple polishing components rotate synchronously via the synchronous pulley 29 and the synchronous belt drive. Example

[0029] like Figure 1-6 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the polishing mechanism further includes a second slide rail 24, one side of which is fixedly connected to the inner wall of the support frame 21, and the surface of the second slide rail 24 is slidably connected to the surface of the mounting frame 23.

The second motor 18 drives the second screw 19 to rotate, causing the second drive block 110 to slide along the guide rod 111, which in turn moves the clamp 112 and clamps the workpiece. During polishing, the first motor 12 drives the first screw 13 to rotate, causing the first drive block 14 and drive plate 15 to move along the first slide rail 16, which moves the placement table 17 to the other end of the polishing table 11. At the same time, the cylinder 22 pushes the mounting bracket 23 to descend along the second slide rail 24, so that the polishing sandpaper 28 contacts the workpiece. The third motor 25 drives the rotating shaft 26 to rotate, and the polishing pressure is transmitted through the buffer rubber layer 27. Multiple polishing components rotate synchronously through the synchronous pulley 29 and synchronous belt drive. After rough polishing is completed, the drive plate 15 moves horizontally to the bottom of the next polishing component and moves sequentially to the sandpaper with increasing grit for fine polishing. The process from rough polishing to fine polishing is seamlessly connected, avoiding the time-consuming error of manually changing components and reducing surface scratches.
