Drill bit grinding machine

Abstract

The invention discloses a drill bit grinding machine. When a drill bit is ground, an operator firstly confirms the blade angle of the drill bit, and a balancing weight is rotated to adjust the included angle between a grinding wheel and the drill bit; an adaptive spring collet is selected according to the rod diameter of the drill bit and the spring collet is mounted into a drill bit rod sleeve; the drill bit to be ground is arranged on a drill bit rod collet through the spring collet, and then a locking nut at the front end of the sleeve is locked; a motor drives the grinding wheel to rotate to grind the blade of the drill bit; and before grinding, the included angle between the grinding wheel and the drill bit is adjusted, the grinding angle is determined, in the grinding process, the blade angle grinding precision of the drill bit is high, operation is easy and easy to learn, the grinding efficiency is improved, and the grinding machine is simple and compact in structure, small in size and low in production cost.

Description

technical field [0001] The invention relates to the field of grinding a drill bit or an engraving tool, in particular to a drill bit grinding machine with high grinding precision, simple and easy-to-learn operation, improved grinding efficiency and low production cost. Background technique [0002] The drill bit grinder is a small tool grinder used for industrial grinding of drill bits. It is used to grind new drill bits after wear and tear, so that the drill bits can be used for repeated grinding and increase the service life of the drill bits. It can grind all kinds of ordinary twist drill bits due to different functions. It is an indispensable helper for drill repair; however, the existing drill grinder is relatively large, with extremely complicated structure and complicated operation, requiring the operator to have certain grinding skills, otherwise the grinding The accuracy is not easy to control; grinding different drill bits requires various accessories, the price of...

[0002] The drill bit grinder is a small tool grinder used for industrial grinding of drill bits. It is used to grind new drill bits after wear and tear, so that the drill bits can be used for repeated grinding and increase the service life of the drill bits. It can grind all kinds of ordinary twist drill bits due to different functions. It is an indispensable helper for drill repair; however, the existing drill grinder is relatively large, with extremely complicated structure and complicated operation, requiring the operator to have certain grinding skills, otherwise the grinding The accuracy is not easy to control; grinding different drill bits requires various accessories, the accessories are expensive, and the relative production cost is very high, so it is not suitable for small-scale processing operations.

[0003] In view of this, the inventor aimed at the many defects and inconveniences caused by the imperfect design of the above-mentioned drill bit grinding equipment, and deeply conceived, and actively researched and improved the trial production and developed and designed this case
