The invention discloses a tool for detecting the assembly precision of an external part of a solid motor case. The surface of one end of a clamping plate is provided with a reference line. The reference line is opposite to the position of a machined margin line of a front skirt of the solid motor case. The surface of the clamping plate is provided with a plurality of rectangular positioning holes which have the same shape as the external part. The plurality of rectangular positioning holes are divided into two groups, and the positions of the two groups of rectangular positioning holes are enabled to be opposite to the designed installation positions of all external parts of the solid motor case in the same quadrant. The tool carries out the simulation of the states of the external parts through the positioning holes after the external parts are welded accurately on the surface of the case, verifies the assembly and welding positions of the external parts in the actual production through the states, enables t
