AI Technical Summary

Technical Problem

When machining hollow tubular cylindrical housings, the existing three-way clamping fixture causes uneven deformation of the clamping area due to the clamping force, which affects the machining accuracy and surface quality, and is also prone to vibration, reducing machining stability.

Method used

The internal support clamping structure, which combines an inner top block with a telescopic tube, is linked with the pressing plate of the outer clamping component and a pressure sensor to form a two-way dynamic clamping. Force balance is achieved through the elastic deformation of the inner top block and the pressing plate to ensure uniform clamping.

Benefits of technology

It achieves stable clamping of hollow tubular cylindrical housings, avoids clamping deformation and vibration, improves machining accuracy and surface quality, and enhances machining stability.
