AI Technical Summary

Technical Problem

Existing drill bit repairers are difficult to accurately correct the cross-edge angle of the drill bit, resulting in poor cutting capabilities of the drill bit, low processing quality, cumbersome operation and high cost.

Method used

A drill bit grinding machine is designed, which adopts a sharpening method combining drill bit rotation and rotation. The top angle is grinding through the movement of the rotation shaft and the oblique angle of the transverse edge, and grinding the rear angle, transverse edge and main cutting edge through the joint movement of the rotation shaft and the rotation shaft.

Benefits of technology

Accurate grinding of all parts of the drill bit is achieved, the cutting capacity and processing quality of the drill bit is improved, the operation process is simplified, and the cost is reduced.

Abstract

The present invention relates to a drill grinding machine, which comprises a frame, a grinding wheel, a revolution device arranged on the frame and a rotation device fixedly connected to the revolution device, a drill bit is fixedly arranged on the rotation device, the grinding wheel machine is arranged corresponding to the drill bit, and a feeding mechanism for controlling the distance between the drill bit and the grinding wheel machine is arranged on the frame; the revolution device is connected to a revolution drive device, the rotation device is connected to a rotation drive device, the revolution axis of the revolution device and the rotation axis of the rotation device are at an angle α of 0° to 50°, the swing angle of the rotation axis is 35° to 40°, and the rotation axis rotates synchronously with the revolution axis. The structure is simple, and the grinding method combining the revolution and rotation of the drill bit is adopted for grinding. Through the movement of the rotation axis, the top angle of the drill bit can be ground and the chisel edge angle can be corrected. Through the joint movement of the revolution axis and the rotation axis, the back angle, chisel edge and main cutting edge of different parts of the drill bit can be ground.
