Automatic detection, marking, sorting and tracing all-in-one machine for bearing rings

The invention belongs to the technical field of automatic detection, marking, sorting and tracing of bearing rings, and discloses an automatic detection, marking, sorting and tracing all-in-one machine for bearing rings, and a detection station is fixedly arranged on the right side of a rotary feeding device; the displacement sensor is fixedly installed on the left side of the upper portion of the second detection station, and the pneumatic measuring head is fixedly installed on the left side of the upper portion of the third detection station. The device has the beneficial effects that the integration of inner diameter detection, height detection, outer diameter detection, sorting of qualified products or inferior-quality products, laser marking of product information and storage of traced product information is realized, and the detection efficiency of the bearing ring is improved; the problems of low laser marking speed and disordered character arrangement in the prior art are solved, automatic recording a
