AI Technical Summary
In the existing technology, the detection efficiency of shaft workpiece outer diameter detection devices is low, making it difficult to adapt to the rapid qualification detection of batch workpieces.
A rapid testing device was designed, comprising a base plate, a base, a mounting plate, a cylinder, a connecting block, and an insert plate. The insert plate is driven by the cylinder to fit against a standard shaft-type workpiece, and the conformal groove is used to fit against the shaft-type workpiece to be tested to determine its qualification. The device is automated by combining a PLC controller and a solenoid valve.
It enables rapid, batch inspection of shaft-type workpieces, improves inspection efficiency, and is suitable for the qualified inspection of batch workpieces.
