Novel punching device for gear production and machining

The invention belongs to the field of punching equipment, particularly relates to a novel punching device for gear production and machining, and aims at solving the problems that an existing gear punching device can only conduct clamping and punching operation on a gear without machined gear teeth, the inner diameter of a machined hole is fixed and cannot be adjusted, the machined gear needs to bemachined and ground again, and the step-by-step operation wastes time and effort. The invention provides the following scheme that the novel punching device for gear production and machining comprises a fixed base, wherein a mounting plate is fixedly connected to one side of the fixed base; and a first supporting plate is fixedly connected to the top of the side, close to the fixed base, of the mounting plate. According to the novel punching device for gear production and machining provided by the invention, a gear machining piece is fixed through a fixing assembly, is punched through a hydraulic cylinder, and is gro
