[0026] A drill bit grinding and cleaning device comprises a cover body 1, connecting holes 2 are provided on both sides of the cover body 1, support plates 3 are symmetrically arranged on both sides of the bottom of the cover body 1, the bottom of the support plate 3 is fixedly arranged on a workbench 100, a first through hole 4 is provided at the bottom of the cover body 1, a dust guide pipe 5 is provided at the bottom of the cover body 1, the top of the dust guide pipe 5 is fixedly connected to the cover body through the first through hole 4, a dust storage box 6 is connected to the bottom of the dust guide pipe 5, the dust storage box 6 is fixedly arranged at the bottom of the workbench 100, a hole for the dust guide pipe 5 to pass through is provided on the workbench 100, and a vacuum pump 7 is also connected to one side of the dust storage box 6, waste chips and dust generated by grinding enter the cover body 1, the vacuum pump 7 evacuates the dust storage box 6, the pressure in the dust storage box 6 is reduced, and the waste chips and dust generated by grinding enter the dust storage box 6 through the dust guide pipe 5 for storage.

[0027] In this embodiment, a grinding assembly is provided on one side of the workbench 100, and the grinding assembly includes a motor 8 and a grinding disc 10. The motor 8 is fixedly arranged on the workbench 100, and the output end of the motor 8 is fixedly connected to one side of the grinding disc 10 through a connecting shaft 9; a clamping device is provided on the other side of the workbench 100, and the clamping device includes a support column 11 and a clamping assembly 12. The clamping assembly 12 is used to fix the drill bit. The bottom end of the support column 11 is slidably arranged on the workbench 100, and the top end of the support column 11 is fixedly connected to the clamping assembly 12. The connecting holes 2 on both sides are respectively sleeved on the connecting shaft 9 and the clamping assembly 12, and the sizes of the connecting holes 2 on both sides are respectively adapted to the connecting shaft 9 and the clamping assembly 12. An elastic sealing ring 21 is also provided on the outside of the connecting hole 2, and the elastic sealing ring 21 is sleeved on the connecting shaft 9 and the clamping assembly 12. The elastic sealing ring 21 does not affect the rotation of the connecting shaft 9 and the clamping assembly 12, and can prevent waste chips generated by grinding from flying out.

[0028] As an implementation method of this embodiment, the bottom of the dust guide pipe 5 is threadedly connected to the box opening of the dust storage box 6, which is convenient for the installation and disassembly of the dust storage box 6. A locking plate 64 is fixedly arranged on the inner side of the box opening of the dust storage box 6. A through hole is opened in the middle of the locking plate 64, and a baffle 61 is hinged in the through hole in the middle of the locking plate 64.

[0033] When the drill bit grinding and cleaning device of this embodiment is in use, when the drill bit is being ground, the vacuum pump 7 is turned on, the pressure in the dust box 6 is reduced, driving the spring 613 to extend and the baffle 61 to rotate toward the inside of the dust box 6, and the waste chips in the cover body 1 can enter the dust box 6 through the dust guide pipe 5. After all the waste chips are transferred to the dust box 6, the vacuum pump 7 stops working, the spring 7 is compressed and reset, driving the baffle 61 to reset, and the baffle 61 just seals the box opening of the dust box 6 under the action of the spring 613, and the waste chips accumulated in the dust box 6 can be cleaned through the box door 63.
