[0002] Drill bits are inevitably subject to severe wear during use, and the cutting edge will be worn out over time, reducing cutting efficiency and increasing labor time. Therefore, drill bits need to be frequently sharpened during use, which requires a drill bit sharpening device. A drill bit sharpening device is a tool used for industrial drill bit sharpening. Due to its different functions, it can sharpen the front angle, positive front angle, top angle, back angle, and side edge of various common twist drills, thin plate drills, and step drills to achieve the purpose of repairing the drill bit as good as new. It is an indispensable helper for drill bit repair.

[0003] After searching, a drill bit cutting edge grinding device with publication number CN216327035U is found, which specifically discloses a drill bit cutting edge grinding device, including a workbench, a stepper motor and a grinder, wherein support columns are arranged at the four corners of the lower end of the workbench, a pad is installed at the lower end of the support column, an operation panel is arranged on one side of the upper end of the workbench, a support frame is arranged on one side of the operation panel, and the stepper motor is arranged on one side wall of the support frame. The beneficial effects are: the utility model adopts the design of clamps, slide grooves, adjusting rods and locking bolts, and the contact area between the grinder and the drill bit cutting edge can be adjusted according to needs, and then the grinder is fixed by the locking bolt, so that the grinding quality can be effectively controlled to ensure the grinding quality of the drill bit, and the design of the stepper motor is adopted, and the drill bit is driven by the stepper motor to rotate forward and reverse at high speed, so that the grinder can grind back and forth in the cutting edge, which greatly improves the grinding efficiency.

[0004] During the use of the existing drill bit grinding device, due to the different shapes of the drill bits, different grinding positions are required, and the grinding head of the grinding device needs to be manually controlled to make the grinding head close to the drill bit gap. This operation method is not only cumbersome and not reproducible, but also has low grinding accuracy. In addition, the above-mentioned comparative case also lacks a positioning function for the drill bit. Therefore, when using the device for drill bit grinding, it is necessary to manually observe the grinding head and the drill bit, which delays the overall grinding time and reduces the grinding accuracy.

[0005] Therefore, it is necessary to invent a drill bit grinding device with a positioning function to solve the above problems. Utility Model Content
