The present invention relates to a technique for adjusting the height of a leveling ring on a drill bit, and more particularly to a height adjusting device for a leveling ring on a drill bit.

It is known that in order to improve the efficiency of a drill bit during drilling operations, it is common to use a computer-controlled drilling device to perform drilling operations in an automated manner.

Because, after the drill bit has been drilled many times, the drill bit will lose the drilling accuracy due to wear. In order to extend the service life of the drill bit, the traditional method is to grind the worn bit through the grinder to make the drill bit Revert to the original drilling accuracy.

However, when the drill bit is subjected to secondary grinding, the total length of the drill bit will become shorter and shorter as the number of grinding times increases, which makes it difficult for the drilling equipment to identify the precise position of the tip, thereby affecting the drilling operation. Therefore, how to obtain the precise position of the tip becomes extremely important.
