The invention provides a device and a method for detecting the coaxiality of an ion optical assembly of a triple quadrupole mass spectrometer, and relates to the field of mass spectrometers. Comprising a V-shaped clamp mounting seat and a guide rod assembly, a laser pen is fixedly mounted on the outer wall of the V-shaped clamp mounting seat, incident laser is arranged in the laser pen, and a second diaphragm is fixedly mounted on the side, close to the V-shaped clamp mounting seat, of the guide rod assembly. A first diaphragm is fixedly mounted on the side, close to the V-shaped clamp mounting base, of the second diaphragm, and a first quadrupole rod quality analyzer assembly is arranged on the side, away from the V-shaped clamp mounting base, of the guide rod assembly. Therefore, the blank of no coaxiality detection means for the ion optical assembly of the triple quadrupole mass spectrometer in the market at present during delivery is filled, and the problem that the delivery consistency cannot be ensured
