High-precision grinding device for drill bit

Abstract

The invention relates to a high-precision grinding device for a drill bit. The high-precision grinding device comprises a base, a grinding mechanism and a clamping mechanism, and the clamping mechanism comprises a connecting base, a circular plate, a clamping assembly and a rotating assembly. According to the high-precision grinding device for the drill bit, rotation of clamping of a main body isachieved through the rotating mechanism and the clamping mechanism, and compared with an existing rotating mechanism, through cooperation of a turbine and a worm, the grinding angle of the main body is controlled during grinding, so that the grinding angle is more accurate; compared with an existing clamping mechanism, the clamping mechanism achieves simultaneous movement of two clamping units inthe direction of a limiting plate through a two-way lead screw, and therefore positioning of the center of the main body is achieved; and meanwhile, the ends, away from a rotating plate, of clamping plates abut against each other through restoring force of springs, so that the clamping effect is improved, the main body is prevented from moving during grinding, the grinding precision is prevented from being affected, and the use practicability is improved.

Description

technical field [0001] In particular, the invention relates to a high-precision grinding device for drill bits. Background technique [0002] Existing grinding drills are often ground by the operator using a grinder and grinding paper. It is difficult to control the grinding accuracy when grinding with a grinder, and the operator is easily burned by sparks during the grinding process, which has a certain degree of danger. , while grinding with grinding paper has higher requirements for operators, not only the grinding efficiency is low, but also it is easy to cause grinding damage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-precision grinding device for drill bits in order to overcome the deficiencies of the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: a high-precision grinding device for drill bits, including a base, a grinding mecha...
