AI Technical Summary
In the current process of hard turning and hard milling of bell-shaped shells, inaccurate positioning is caused by dirt adhering to the positioning ring, which affects coaxiality and accuracy, resulting in a decrease in product qualification rate and an increase in scrap rate, thus increasing production costs.
Design a positioning ring with a gas guide hole and a gas pressure monitoring system. The gas pressure sensor monitors the gas pressure in the gas channel in real time, and a buzzer alarm indicates poor positioning. This ensures the sealing between the bell-shaped shell and the positioning ring and prevents misalignment during installation.
This improved the coaxiality and precision of bell-shaped shell products, reduced the scrap rate, and decreased production costs.
