摘要
分析电力和内燃机车直流牵引电机换向器的结构特点,研究其云母槽自动下刻加工的关键技术,并针对现有云母槽下刻加工检测系统的不足,提出一种双探针接触式的检测方法,建立其数学模型,并设计相应的检测系统。采用这种检测方法,能准确识别云母槽与铜排的边界、快速计算出云母槽中心线位置及其相对于电枢轴线的偏角,实现偏差补偿。试验表明,该方法有效地提高了检测系统在获取换向器表面信息时的准确度和可靠性,是一种经济、高效、简便的方法。
The structural eharaetersfic of motor commutator in electric locomotive and interual-eombustion locomotive was anallyzed. The key technology of miea-slot automatically chiseling was researched. A two-probe-contact detecting method was presented aimed at the deficiency of the existing detection system of the electromotor mica-slot chiseling machine. The mathematical model was established and the detection system was designed. Using this improved detection method, the boundary of mica-solt and the copper- bar could be identified accurately, and the mica-slot centerline could be calculated quickly. Regarding the angle between the mica-slot centerline and the armature axis, the compensation for the deviation was realized appropriately. The experimental reuh indicates that this method can improve the detection system＇s accuracy and reliability effectively when it gains the commutator surface information. It is economic, efficient and simple
