Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a rapid positioning tooling for planetary gear processing. Background Art

[0002] Planetary gears generally refer to planetary gears. Planetary gears refer to gear systems that can rotate around their own rotation axes like fixed-axis gears, and their rotation axes also rotate around the axes of other gears along with the planet carrier. Rotation around their own axis is called "rotation", and rotation around the axes of other gears is called "revolution", just like the planets in the solar system, hence the name;

[0003] Gear grinding is a common processing operation for planetary gears. When grinding planetary gears, the planetary gears often need to be mounted on a chuck and clamped and positioned using claws. However, the claws will block some of the gear teeth. After grinding most of the gear teeth, the planetary gears need to be removed and re-clamped to expose the previously blocked gear teeth. Only then can all the gear teeth be ground. This is not only time-consuming and labor-intensive, but also affects the speed of planetary gear processing. To this end, a quick positioning tool for planetary gear processing is proposed.
