Vibration measurement equipment for fault detection of numerical control machine tool

The invention discloses vibration measurement equipment for fault detection of a numerical control machine tool, and belongs to the field of vibration measurement equipment. The vibration measurement equipment comprises a shell, a connecting line is arranged in the shell, one end of the connecting line is fixedly connected with a probe shell, a sleeve is arranged in the lower end of the probe shell, and the outer surface of the probe shell is sleeved with a sliding sleeve; three sets of sliding grooves are evenly formed in the positions, close to the upper end, of the side surface of the probe shell. After detection is completed, the distance between the sliding sleeve and the first strong magnetic ring is controlled to be increased, magnetic attraction force borne by iron-containing small impurities on the surface of the sliding sleeve is gradually reduced, the iron-containing small impurities fall off from the lower end of the sliding sleeve due to the gravity of the iron-containing small impurities and are
