Gear machining clamping tool

The utility model discloses a gear machining clamping tool and belongs to the field of gear machining. According to the gear machining clamping tool, the transmission assembly and the containing assembly are arranged, so that the effect of effectively limiting a machined gear can be achieved in the using process of the gear machining clamping tool, and when the gear needs to be clamped and fixed, the gear can be clamped and fixed; a worker only needs to control the transmission assembly to drive the clamping assembly to generate displacement, the gear can be well fixed, and the situation that the gear needs to be fixed manually is effectively avoided. According to the gear grooving device, a good transmission effect can be achieved in the using process by arranging a rotating motor and a transmission disc, a good fixing effect on a gear can be effectively guaranteed in the using process by arranging a clamping assembly, and the effect of grooving the inner side and the outer side of the gear at the same time
