A valve seat takeoff apparatus is provided to take off all kinds of valve sea rings on demand regardless of sorts of valve seats by using a bench drill-like unit in no need of processing unit. A valve seat takeoff apparatus comprises: a groove machining device to process grooves inside the valve seat by using a rotating cutter driven by a motor; and a takeoff device(20) to hold a handle of a screw-joining structure on the groove of the valve seat in order to take off the valve seat upward. After the groove is processed on the seat, the valve seat is held by the groove in order to be separated from a cylinder head. The groove machining device consists of a motor, a shaft, a cutter, a head part with an up/down handle, a base to support the motor and head part, a post and a left/right handle to move the head part at constant angle. |
