Gear processing machines that use hobs to process spur, helical and herringbone cylindrical gears and worm wheels by the development method. This type of machine tool can also process workpieces with various special tooth shapes such as splines and sprockets when using special hobs.

[0003] The patent document with publication number CN211680365U discloses a gear hobbing machine that is easy to cut, which belongs to the technical field of gear hobbing machines. It includes a machine body, a gear hob installed on the machine body, a workbench rotatably connected to the machine body near the gear hob, and a tooling fixture fixedly connected to the workbench. The tooling fixture includes a positioning column fixedly connected to the workbench and a gasket sleeved on the positioning column. The gear blank can abut against the gasket. The workbench is connected to a tightening component that can tighten the gear blank on the gasket, and the gasket is connected to a lifting component that can push the gasket up and down.

[0004] In the above technical solution, during the unloading process, the pad is pushed up by the lifting cylinder to push the processed gear to the top of the positioning column, and then the staff pushes the processed gear to the inclined slide. The gear slides along the inclined slide into the receiving box for stacking. This process requires manual intervention, which will reduce the efficiency of use. After the gear slides out on the inclined slide, it is easy to collide with the gear below due to inertia. Therefore, we propose a gear hobbing machine that is easy to unload to solve this problem.
