[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figure 1As shown, a device for removing brake drum blank residue in this embodiment includes a worktable 9. A three-jaw chuck 8 is installed at the center of the top of the worktable 9. A composite jaw 6 is installed on the three-jaw chuck 8 by a high-strength hexagonal screw 7. Replaceable pads 4 are installed in a ring around the outside of the composite jaw 6. A high-strength hexagonal screw 13 is installed between each pad 4 and the composite jaw 6. A workpiece 3 is installed on the outside of the pad 4. The upper part of the workpiece 3 has an inner flash 11, and the lower part of the workpiece 3 has an outer flash 5. A guide rail 1 is provided above the workpiece 3. An internal cutting component 2 is installed at the bottom of the guide rail 1, directly opposite the inner flash 11. The internal cutting component 2 includes an inner telescopic cutter arm 201, an inner cutter holder 202, and an inner blade 2. 03. An external cutting component 10 is installed at the bottom of the guide rail 1 directly opposite the outer burr 5. The external cutting component 10 includes an external telescopic cutter arm 1001, an external cutter holder 1003, and an external blade 1002. When grinding the inner burr 11 and the outer burr 5 on the workpiece 3, the workpiece 3 is first installed on the composite jaw 6, and the positions of the internal cutting component 2 and the external cutting component 10 on the guide rail 1 are adjusted to ensure that the inner blade 203 is in contact with the inner burr 11 and the outer blade 1002 is in contact with the outer burr 5. Then, the power component in the worktable 9 is used to rotate the three-jaw chuck 8, so that the inner burr 11 and the outer burr 5 can be ground and removed at the same time as the workpiece 3 rotates with the three-jaw chuck 8.

[0022] like Figure 1 As shown, in this embodiment, a drive shaft 12 is installed at the power output end of the drive component inside the worktable 9. The drive shaft 12 is connected to the three-jaw chuck 8. The drive shaft 12 is mainly used to transmit the power of the internal power component of the worktable 9 to the three-jaw chuck 8, ensuring the convenient rotation of the three-jaw chuck 8. A high-strength internal hexagon screw 2 7 passes through the composite jaw 6 and is threadedly connected to the three-jaw chuck 8. A high-strength internal hexagon screw 1 13 passes through the pad 4 and is threadedly connected to the composite jaw 6. The composite jaw 6 and the pad 4 cooperate to achieve reliable positioning of workpieces 3 of different models.

[0023] like Figure 1 As shown, in this embodiment, the fixed part of the inner telescopic cutter arm 201 is connected to the guide rail 1 through a limitable slider. The inner cutter holder 202 is bolted to the telescopic part of the inner telescopic cutter arm 201. The inner telescopic cutter arm 201 allows the height of the inner blade 203 to be adjusted according to actual usage needs, ensuring that the inner blade 203 can always contact the inner flash 11 on the workpiece 3. The inner blade 203 is bolted to the inner cutter holder 202. The cutting head of the inner blade 203 faces the inner flash 11. During the rotation relative to the inner blade 203, the inner flash 11 is ground by the inner blade 203 to remove the inner flash 11.

[0024] like Figure 1As shown, in this embodiment, the fixed part of the outer telescopic cutter arm 1001 is connected to the guide rail 1 through a limitable slider. The outer cutter holder 1003 is bolted to the telescopic part of the outer telescopic cutter arm 1001. The outer telescopic cutter arm 1001 allows the height of the outer blade 1002 to be adjusted according to actual usage needs, ensuring that the outer blade 1002 can always contact the outer flash 5 on the workpiece 3. The outer blade 1002 is bolted to the outer cutter holder 1003. The cutting head of the outer blade 1002 faces the outer flash 5. During the rotation relative to the outer blade 1002, the outer flash 5 will be ground by the outer blade 1002 to remove the outer flash 5.

[0025] The specific implementation process of this embodiment is as follows: When grinding the inner flash 11 and outer flash 5 on the workpiece 3, firstly, select the corresponding model of pad 4 according to the size of the workpiece 3, and install the pad 4 on the composite jaw 6. Then, install the workpiece 3 on the composite jaw 6, and adjust the positions of the inner cutting component 2 and the outer cutting component 10 on the guide rail 1 respectively to ensure that the inner blade 203 contacts the inner flash 11, and at the same time ensure that the outer blade 1002 contacts the outer flash 5. Finally, simply start the power component in the worktable 9 to make the drive shaft 12 rotate, so that the workpiece 3 can rotate with the three-jaw chuck 8. This grinding device achieves simultaneous grinding and removal of both inner flash 11 and outer flash 5. Through the coordinated design of the guide rail 1, inner cutting component 2, outer cutting component 10, replaceable pad 4, composite jaw 6, and three-jaw chuck 8, the inner and outer flash 11 on the workpiece 3 can be simultaneously ground and removed during its rotation using the inner cutting component 2 and outer cutting component 10. This avoids the tedious manual grinding process, reduces labor intensity, improves grinding efficiency, and minimizes the impact of dust and noise on the working environment.
