AI Technical Summary
Existing clamping devices for machining shaft parts rely on manual fixation, which is time-consuming and labor-intensive, reducing clamping efficiency.
The system employs adjustment and drive components. A servo motor drives a bidirectional threaded rod to adjust the spacing of the movable blocks, while a bidirectional cylinder drives a pressure rod to synchronously clamp the shaft. Combined with a polyurethane anti-slip plate, it achieves fast and precise clamping and fixing.
It enables rapid and precise clamping of shaft components, improves assembly and fixing efficiency, reduces manual labor intensity, and ensures processing quality.
