Tappet full automatic eddy current testing system is a full automatic crack hardness sorter that integrates light, electricity and machinery. The whole system includes a main control system, charging system and mechanical transmission system. The workpiece is sent to the area to be inspected by clamping and transverse moving. The workpiece surface is scanned by a point probe, which can inspect the outer circle, bottom surface and chamfered end surface of the tappet at the same time. At the same time, the system also supports automatic charging, automatic detection and automatic sorting. It can also be connected to the production line of the factory and can be selected for off-line automatic detection and sorting.
