AI Technical Summary

Technical Problem

Traditional rigid turning centers are prone to vibration and stress concentration during workpiece clamping or machining, which affects machining accuracy and shortens equipment life. In addition, the complex structural design makes component replacement inconvenient.

Method used

A rigid actuating tip with a buffer mechanism is designed. A pressure spring is used to absorb impact energy. Combined with the fitting effect of the limiting body and the guide cylinder, the coaxiality of the ejector pin is ensured. The rapid response of the pawl is achieved through the meshing of the tooth block group and the guide gear, which simplifies the replacement of the pawl and ejector pin.

Benefits of technology

It achieves a buffering effect during workpiece clamping, improves machining accuracy and efficiency, simplifies the replacement of worn parts, and extends the service life of the equipment.
