AI Technical Summary

Technical Problem

Traditional hydraulic cylinder return detection methods are difficult to install in electric spindles and are easily affected by vibration and oil contamination. They have low detection accuracy and cannot meet the precise detection requirements of multiple critical positions, posing safety hazards and machining quality problems.

Method used

Multiple inductive sensors are arranged on the end shell of the electric spindle. Precise detection is achieved by the conical object being detected contacting the sensor. The sensor position is adjusted by combining the adjustment groove and the pad structure to ensure detection accuracy.

Benefits of technology

It enables precise detection of the return state of the hydraulic cylinder piston rod, avoiding unstable clamping and machining errors, improving the operational reliability and safety of the electric spindle, and ensuring machining accuracy and efficiency.
