摘要:

为解决导电滑环弹性合金丝接触位置和距离测量的难题,提出了一种基于视觉检测的轴向接触位置测试方法。设计等效仿形滑环及轴向位置测试装置,应用视觉检测提取弹性合金丝的张角、安装距离及轴向接触位置。试验中,以滑环直径和电刷板安装距离为边界条件,考察二者对轴向接触位置的影响。试验结果表明,直径与安装距离显著影响轴向接触位置距离与张角的变化规律。相较于传统方法,所提方法的测试误差和重复测试误差分别控制在0.03 mm和0.0065 mm,可精确提取接触位置数据,有效揭示接触状态变化的作用机制,实现对导电滑环接触特性的高精度测量与优化,为高精密设备提供了可靠的测量手段。

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 detection. 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 installation 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 the installation 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 0.03 mm and a repeatability error of 0.0065 mm, 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.
