Summary: | The invention discloses a drill bit positioning device of a cantilever heading machine. The machine comprises a positioning bearing table, a rotation angle adjusting mechanism, a rotation angle limiting mechanism, a vertical angle adjusting mechanism, a rotation angle control device, a buffer damping mechanism and a universal wheel; the rotation angle control device is arranged on one side of the positioning bearing table; and a drill bit body is arranged on the upper surface of the positioning bearing table. According to the drill bit positioning device of the cantilever heading machine, through the arranged rotation angle adjusting mechanism, when the drill bit body is placed on the positioning bearing table, and the rotation angle of a drill bit needs to be adjusted, a servo motor in the rotation angle adjusting mechanism operates, and a driving gear in rotation angle control device can rotate; inclined clamping teeth on the surface of the driving gear are meshed with clamping teeth on the surface of a dri |
