AI Technical Summary
Ceramic tube shells are prone to breakage when processed using traditional mechanical internal clamping, and local stress concentration during clamping leads to a high scrap rate.
The system employs a combination of thin and thick cylinders. Air is introduced into both cylinders via an air intake mechanism, causing the rubber ring to expand evenly and fit against the inner wall of the ceramic tube shell, achieving flexible clamping and avoiding localized stress concentration.
It significantly reduces the risk of ceramic tube shell breakage, improves the versatility and machining accuracy of the fixture, and is particularly suitable for high-precision, low-damage machining of alumina ceramic tube shells in the power electronics industry.
