The invention discloses an automatic measuring and sorting device for shaft type parts and belongs to the technical field of precision testing and measuring. The automatic measuring and sorting devicefor the shaft type parts comprises a mechanical part and a measuring and controlling part; and the mechanical part comprises a vibration material disk, a feeding pipe, a material hopper cabinet body,a rack cabinet body, a stock bin assembly, a rotating disk assembly, an inner diameter measuring assembly, a length measuring assembly, a discharging assembly, a control box and the like. The measuring and controlling assembly comprises a PLC, a rotating disk motor, an inner diameter measuring motor, a rotating disk motor driver, an inner diameter measuring motor driver, a human-computer interface, an air gauge, a long grating and the like. According to the automatic measuring and sorting device for the shaft type parts, the mechanical structure of a six-station rotating disk is adopted, themeasuring method of the air gauge and the long grating is used, full-automatic and high-precision online measuring on the inner diameter and the length of the shaft type parts is achieved, and qualified products, products sent back for repairing and unqualified products are sorted according to the measuring result. The automatic measuring and sorting device for shaft type parts has the beneficialeffects of being high in work efficiency and reliability, good in repeatability and the like, and the labor intensity of an operator and the production cost of an enterprise are effectively lowered.
