AI Technical Summary
During the roll processing, the tailstock device causes the roll to vibrate and pop out, affecting the processing accuracy. In addition, the excessive gap between the rolls during winding leads to deviations.
A clamping tailstock for rolling mills was designed. The connection stability is enhanced by the elastic tension of the spring and the threaded connection between the connecting stud and the hexagonal screw platform. The fixing effect is improved by using the cross connecting groove and the tapered shank mechanism to avoid positional deviation.
It effectively avoids vibration and popping of the roll during processing, improves connection stability, and ensures processing accuracy and winding consistency.
