Abstract

The application belongs to the technical field of surface defect detection, and particularly relates to a forging part surface defect detection device, which comprises a base and a PLC control host computer, and further comprises: a material clamping and transferring mechanism fixedly arranged on the base and used for fixing an annular forging part to be detected; a pretreatment mechanism fixedly connected to one side of the upper end of the base and used for treating impurities and dirt on the surface of the forging part before detection; a positive heating mechanism fixedly connected to the rear side of the upper end of the base and located directly above the material clamping and transferring mechanism; and a thermal imaging detection mechanism. The application is adapted to high-temperature working conditions by means of non-contact detection, is not affected by material magnetism and conductivity, can penetrate a thin oxide layer, quickly covers a complex curved surface, accurately identifies micro-cracks, pits and other defects, greatly improves detection accuracy and efficiency, and simultaneously reduces manual labor intensity.
