Description

Technical Field

[0001] The utility model relates to the technical field of drill bit grinding, and in particular to a drill bit grinding device. Background Art

[0002] The drill bit grinding device is a small tool grinder used for industrial drill bit repair. Its diverse functions allow it to grind the rake angle, positive rake angle, top angle, back angle, and side edges of various common twist drills, special-shaped drills, Nizhifu drills, sheet metal drills, and step drills, restoring the drill bit to its original appearance. It is an indispensable tool for drill bit repair.

[0003] The processing of drill bits requires the use of a grinding device, but the existing drill bit grinding device still has some shortcomings. For example, if the front end of the drill bit is ground by a grinding wheel and is not cooled in time, the front end of the drill bit will be deformed by heat, thereby causing the blade angle to change and making it impossible to drill. At the same time, when grinding the existing drill bit, the clamp is inconvenient to operate, and clamping and loosening are both difficult. In addition, the grinding device is prone to vibration and deviation during operation, resulting in inaccurate grinding.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content
