Most existing workpieces are placed on machine tools and fixedly clamped on both sides of the workpiece. After the quenching of the upper surface is completed, the staff needs to disassemble the workpiece and manually turn the workpiece over so that its lower surface faces upward before quenching again. The labor intensity is high, the operation is complicated, and the work efficiency is low. Utility Model Content
