Diamond drill bit convenient to disassemble

Abstract

The invention discloses a diamond drill bit convenient to disassemble. The diamond drill bit convenient to disassemble comprises a rotating shaft and a sleeve. The outer wall of the sleeve is sleevedwith the inner wall of the rotating shaft. A drill bit body is fixedly connected to the bottom of the sleeve, diamond cutter teeth are uniformly distributed at the bottom of the drill bit body, clamping grooves are formed in both sides of the sleeve, and positioning blocks are arranged on the positions, corresponding to the clamping grooves, of the outer wall of the rotating shaft. Through holes are formed in the positions, corresponding to the clamping grooves, of the outer wall of the rotating shaft in a penetrating mode. Clamping blocks are connected to the inside of the clamping grooves ina clamping mode, and the one ends, away from the inside of the clamping grooves, of the clamping blocks sequentially penetrate through the through holes and the positioning blocks and extend to the outside of the rotating shaft. The drill bit body and the diamond cutter teeth can be conveniently taken down from the inside of the rotating shaft, the diamond cutter teeth can be conveniently maintained, and the working efficiency of drilling and polishing can be enhanced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of diamond tools, in particular to a diamond drill bit which is easy to disassemble. Background technique [0002] The drill that makes the cutting edge is called a diamond drill. The drill bit is a one-piece drill bit. The whole drill bit has no moving parts and has a relatively simple structure. It has high strength, high wear resistance and impact resistance. It is one of the three new technologies of drilling in the world in the 1980s. Field use proves that when drilling in soft-medium hard formations, diamond bits have the advantages of fast speed, more footage, long life, stable work, fewer downhole accidents, and good wellbore quality. The diamond drill bit not only has a long service life, but also can be reused. The diamond drill bit returned to the factory for repair has the same effect as the factory diamond drill bit, which can save a lot of drilling costs. [0003] When the drill bit is in use...

AI Technical Summary

Problems solved by technology

[0003] When the drill bit is in use, because it needs to grind hard geology such as rock layers for a long time, it will cause serious damage to the diamond cutter teeth, which will affect the service life of the diamond drill bit. After the diamond cutter teeth are damaged, they will be discarded or returned to the factory for maintenance. The entire drill bit must be removed when returning to the factory for maintenance or discarding, and the traditional diamond drill bit is not easy to disassemble. Therefore, we propose a diamond drill bit that is easy to disassemble
