The utility model relates to a punching clamp capable of guaranteeing concentricity. The punching clamp capable of guaranteeing concentricity comprises a first clamp body, a second clamp body, an adapting piece and a locating block. The first clamp body and the second clamp body are fixedly connected through the adapting piece. A first fixing round groove is formed in the center of the end face of one side of the first clamp body, wherein the side of the first clamp body is opposite to the second clamp body. A square groove and a second fixing round groove are sequentially formed in the end face of one side of the second clamp body, wherein the side of the second clamp body is opposite to the first clamp body. The second fixing round groove and the first round groove are concentric. The locating block is arranged on the outer end face of the second clamp body. A first locating hole is formed in the center of the locating block, and the first locating hole and the second fixing round groove are concentric. Second locating holes are formed in the outer end face of the locating block, and are distributed in a circular array mode. The second locating holes are communicated with the second fixing round groove. Third locating holes are formed in the outer end face of the second clamp body, and are distributed in the circular array mode. The third locating holes are communicated with the square groove. The punching clamp capable of guaranteeing concentricity is capable of guaranteeing concentricity between each group of two groups of round holes and a center hole processed on a workpiece.
