Description

Technical Field

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

[0002] A gear is a mechanical component with gears on the wheel rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of gear cutting was developed and special machine tools and cutters that used this principle to cut gears appeared one after another. With the development of production, the smoothness of gear operation has received attention and it is a more commonly used mechanical component.

[0003] During the processing of gears, holes need to be drilled on their surfaces, which can not only reduce the weight of the gears and make them lightweight, but also facilitate the connection of the gears to other components through the drilled holes. It is a necessary part of the gear production process. The existing gear drilling device drives the carbide drill bit or tungsten steel drill bit to rotate through the drilling machine, and the crank keeps moving to move the drill bit toward the gear, thereby completing the drilling process.

[0004] However, the existing gear drilling device is unable to perform multi-directional drilling. During the drilling process, the gear is first clamped and fixed directly below the drilling machine so that the drill bit corresponds to the center of the gear. If multiple holes are to be drilled, the gear position needs to be readjusted, which is troublesome and reduces work efficiency. Therefore, a new solution is needed to solve this problem.
