Clamping device for ferrite nodular-milling iron casting machining

The utility model relates to the technical field of iron casting machining, and discloses a clamping device for ferrite nodular-milling iron casting machining, which comprises a supporting base and a clamping table which is arranged on the top of the supporting base and rotates in a matched mode. At the moment, clamping tightening latches are controlled through a driving rotating rod, so that the two sets of clamping tightening latches close to, clamp and fix a machined part through clamping pads, and when the bottom or other dead angle parts of the machined part need to be machined, a movable ring block can be controlled to rotate in a limiting groove through stirring of a stirring rod; according to the device, the clamping tightening latches are arranged, a machined part clamped between the two clamping tightening latches rotates in all directions, the grinding angle position of the machined part is increased, the machined part is prevented from being repeatedly clamped and disassembled, a fixed rod in a co
