| titleOfInvention | A quality detection device for motor carbon brush holder |
| abstract | The utility model discloses a quality detection device for a carbon brush holder of a motor, which comprises a guide block for pressing the carbon brush upwards into the brush holder, a tuning fork arranged at the rear of the guide block and capable of being excited by the carbon brush, a pickup for receiving the sound signal of the tuning fork, and Acoustic analysis component to which the pickup wire is attached. The utility model excites the tuning fork by pressing the carbon brush into the brush holder and then rebounding, and judges the strength of the rebound of the carbon brush by monitoring the intensity of the sound of the tuning fork through the pickup and the sound wave analysis component. There is a quality problem, which solves the problem of inaccurate judgment and inability to quantify the speed of manual manual measurement or visual rebound. The brush holder with qualified quality will not affect the rise and fall of the carbon brush, and the brush holder with unqualified quality will hinder the carbon brush. The rise and fall of the brushes cause the carbon brushes to fail to excite the tuning fork or the sound waves generated by the tuning forks do not meet the criteria set by the sonic analysis component. |
