Measuring equipment for brake disc

The invention provides brake disc measuring equipment which comprises a rack, a sealing box assembly, a first conveying line and a first transfer assembly, sound collection is carried out in a sealed space, the sealing box assembly is separated from the first conveying line and the first transfer assembly, the external influence of the first conveying line and the first transfer assembly on the sealing box assembly is avoided, and the measurement accuracy is improved. In order to avoid the internal influence of the sealing box assembly, the positioning piece, the knocking piece and the microphone are all located in the sealing box. The positioning piece is used for positioning the brake disc; the knocking piece moves relative to the positioning piece and is used for knocking the brake disc positioned by the positioning piece; and the microphone is arranged relative to the knocking piece and is used for collecting the sound emitted by the brake disc, so that the accuracy of the sound emitted by the brake disc
