The invention discloses an integrated inspection tool for a single stamping part and a welding assembly. The tool comprises a clamping unit and a supporting unit opposite to the clamping unit, whereinthe clamping unit comprises a driving part, a first switching part and a clamping part; the first switching part is connected with the clamping part, and is used for switching the clamping part amonga plurality of clamping positions; the driving part is connected with the first switching part to drive the clamping part to clamp a to-be-tested part on the supporting unit; the supporting unit comprises a supporting part and a second switching part; a supporting surface is formed on the supporting part; and the second switching part is connected with the supporting part, and is used for switching the supporting part among a plurality of supporting positions. Compared with the prior art, the tool has the advantages that the state consistency of the stamping part and the welding assembly is truly reflected, and a detection result can provide a direction and a basis for die debugging and clamp debugging, so that the debugging period is shortened.
