High-precision precision workpiece detection sorting machine

The utility model discloses a high-precision precision workpiece detection sorting machine which comprises a first machine frame and a second machine frame. A feeding mechanism is arranged on the first machine frame. The second machine frame is provided with a first metal rotating disc and a second transparent rotating disc which are driven by a power device and a first conveying mechanism for conveying workpieces from the feeding mechanism to the first rotating disc. A first sensor, a vertical face size detection mechanism, a second conveying mechanism used for conveying the workpieces on the first rotating disc to the second rotating disc and a first material collection mechanism are arranged on the first rotating disc in the circumferential direction. A second sensor, a transverse face size detection mechanism, an appearance detection mechanism and a second material collection mechanism are arranged on the second rotating disc in the circumferential direction. An electric control unit used for controlling the parts to act in a coordination mode is further arranged on the machine. The machine achieves mechanical assembly-line-type automatic detection. Surface grinding processing can be conducted by the first rotating disc in the machining later stage, the vertical face size detection accuracy is improved, the detection and sorting efficiency is improved, detection of the workpieces of different shapes can be achieved, and generality is improved.
