The invention provides a tool for measuring an assembly size of a finished part. The tool is used for measuring the size of a finished part of a circular cabin body,and comprises a measuring base,a self-checking plate and a detection sample column,wherein the bottom face of the measuring base is a cambered surface matched with the camber of the cabin body,the measuring base is used for fitting thesurface of the cabin body during measurement,the top face of the measuring base is located in a flat when the tool is located in a measuring position; a measuring hole cooperating with a to-be-measured portion is formed in the measuring base; the detection sample column can be located in the to-be-measured portion through the measuring hole; the self-checking plate at the side of the measuring hole is rotationally arranged on the measuring base,is an assembly produced according to a go-no go fixed gauge principle,and can quickly detect whether or not the size of the to-be-measured portion iswithin a tolerance range through the cooperation with the detection sample column. The tool for measuring assembly sizes of finished parts improves the measurement efficiency and measurement result reliability of the measurement,thereby improving the assembly efficiency of the finished part.
