[0002] After metal components are cut, there will be many burrs on the cut surface, which need to be cleaned with a grinding device. When cleaning the burred surface of a metal sheet, a manual handheld grinder is usually used to clean the burrs on the surface of the metal sheet. During the cleaning process, the position of the metal sheet is easily affected by the grinder and shifted, so that the grinding sheet grinds the surface of the metal sheet, causing the surface to be scratched, resulting in processing errors, which not only affects the use of the metal sheet, but also causes unnecessary losses.

However, during use, since the size of the placement groove opened on the side where the clamping blocks are close to each other is fixed, only metal parts of corresponding thickness can be fixed, and the adaptability range is small. After grinding one side of the metal part, it needs to be adjusted to the other side, which is not convenient to use, thereby affecting the grinding efficiency of the metal part.

[0021] Among them, the placement platform 2 includes a connecting plate 21, both ends of the bottom of the connecting plate 21 are fixedly connected to the limit blocks 26, one side of the connecting plate 21 is fixedly connected to a clamping motor 25, a clamping groove 22 is opened inside the connecting plate 21, the middle part of the connecting plate 21 is located in the middle of the clamping groove 22 and is fixedly connected to a placement platform 23, one side of the clamping motor 25 is fixedly connected to a bidirectional screw 24, the bidirectional screw 24 is rotatably installed inside the placement platform 23 and the clamping groove 22 respectively, the bottom of the connecting plate 21 is fixedly connected to the rotating block 16, and the limit block 26 is slidably installed inside the sliding groove 17.

[0022] The height of the placement table 23 is the same as the height inside the clamping block 31 . Therefore, when the metal piece is placed on the surface of the placement table 23 , the clamping motor 25 rotates the bidirectional screw 24 , and the clamping blocks 31 move toward each other, thereby clamping both ends of the metal piece.

[0023] As attached Figure 4-5 As shown, the clamping device 3 includes a clamping block 31, a movable slider 39 is fixedly connected to the bottom of the clamping block 31, the movable slider 39 is threadedly connected to the outer surface of the bidirectional screw 24, and the movable slider 39 is slidably installed inside the clamping groove 22. Limiting grooves 32 are provided at both ends of one side of the clamping block 31, and the limiting rod 33 is fixedly connected inside the limiting groove 32.

When the inclined surface of the extrusion block 310 pushes the inclined surface of one side of the fixing block 311, it is subjected to the extrusion force, causing the fixing block 311 to move toward each other, thereby clamping both sides of the metal piece, so that the metal piece is fixed. At the same time, it can adapt to metal pieces of different thicknesses.
