Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine for gear processing. Background Art

[0002] Gears refer to mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. During the production process, gears need to be forged, normalized, turned, rolled, gear-shaped, shaved and drilled. Drilling is the process of opening holes in the gears using a drill on a drilling machine.

[0003] An existing gear processing drilling machine (publication number: CN219581720U) has at least the following disadvantages:

[0004] When the above patent is in use, two of the sliders are first pushed manually to make the three sliders abut against the outer surface of the gear, and then the positions of the sliders are fixed by manually tightening the bolts on the three sliders to make the sliders position the gears. Since the above patent requires manual loosening of the bolts every time the gears are replaced, the method of manually tightening the bolts is too cumbersome and inconvenient for operators to use.
