The invention provides a vertebral plate rongeur machining clamp. The vertebral plate rongeur machining clamp comprises a machine tool worktable, a four-axis dividing plate, a right handle clamping device, a left handle upper portion machining clamping device, a left handle lower portion machining clamping device and a cover plate machining clamping device; the right handle clamping device is usedfor machining a right handle of a vertebral plate rongeur, the left handle upper portion machining clamping device is used for machining a left handle upper portion of the vertebral plate rongeur, the left handle lower portion machining clamping device is used for machining a left handle lower portion of the vertebral plate rongeur, and the cover plate machining clamping device is used for machining a cover plate of the vertebral plate rongeur; multiple parts are clamped at one time, equivalently, workpiece centralized clamping is achieved, compared with previous one-piece clamping, clampingtime is reduced, in the previous method, clamping needs to be carried out at eight times, now, only one concentrated one-time clamping is needed, during assembly, whole-set one-to-one corresponding assembling is needed during machining, and the assembling success rate of the parts is high.
