Abstract： To address the challenges of measuring the contact position and distance of elastic alloy wires in conductive slip rings，an axial contact position testing method was proposed based on visual detec tion.By designing an equivalent profiling slip ring and an axial position testing device，visual detection was applied to extract the angle，installation distance，and axial contact position of the elastic alloy wires. In the tests，the slip ring diameter and the instalation distance of the brush plate were used as boundary conditions to investigate their influences on the axial contact position. The testing results show that the diameter and thelinstallation distance significantly affect the variation laws of the axial contact position distance and the opening angle. Compared with the traditional methods，the proposed method achieves a testing error of 0.03mm and a repeatability error of 0.0065mm ，accurately extracting contact position data. It effectively reveals the action mechanism of contact state changes，realizes high-precision measurement and optimization of the contact characteristics of conductive slip rings，and provides a reliable measurement means for high-precision equipment.
