Background

The drill bit is a common tool used by people in work and life, and the drill bit has various types, such as a twist drill bit, a percussion drill bit, a woodworking drill bit and the like. During the machining and use of the drill bit, the drill bit needs to be frequently ground to ensure the sharpness of the drill bit.

Currently, drill grinding systems are often used to grind drill bits. However, in the grinding process, cutting, scratching and scratching are generated between the grinding wheel and the material, a large amount of grinding heat is generated, the temperature of a grinding area can reach about 400-1000 ℃, the material can be deformed and burnt at the high temperature, the grinding wheel can be seriously worn, and the grinding quality is reduced. Therefore, during the grinding process of the drill bit, a large amount of grinding heat is generally taken away by using grinding fluid, and the temperature of a grinding area is reduced. Most of the existing grinding fluid directly flows to a base of a drill grinding system after washing a drill and a grinding wheel and then is discharged through an oil discharge hole in the base, however, the base is also provided with a threading hole for various power lines, signal lines and other wire harnesses of the drill grinding system to pass through except the oil discharge hole, and part of the grinding fluid easily flows out of the threading hole along the power lines, the signal lines and other wire harnesses, so that the grinding fluid is leaked to cause waste of the grinding fluid and the base of the drill grinding system is polluted by the grinding fluid.

Therefore, there is a need for an improved structure of a conventional drill bit grinding system at a threaded hole to prevent a grinding fluid from leaking from the threaded hole along various power and signal lines of the drill bit grinding system.
