Positioning and punching device for frame mounting plate

The utility model discloses a positioning and punching device for a frame mounting plate, which relates to the technical field of frame mounting plate processing, and is characterized in that a shifting rod pulls a pressing block to drive a stop block to move in a hole cavity, so that a pressure spring generates elastic deformation, the pressing block completely enters the hole cavity, and the positioning and punching device is used for punching the frame mounting plate. A workpiece to be machined is placed in the containing groove in the top face of the positioning base, punching of the workpiece to be machined is facilitated, then pulling force acting on the poke rod is removed, the pressing block leaves the interior of the hole cavity and moves to the initial position, the bottom face of the pressing block makes contact with the top face of the workpiece to be machined, the workpiece to be machined is blocked, and the workpiece to be machined is rapidly fixed. The stability of a machined workpiece during d
