针对目前汽车同步带齿形轮廓参数测量过程中存在的测量效率低和人为因素影响大等问题,提出了一种基于激光三角法的汽车同步带齿形轮廓参数非接触式测量方案,并设计了相应的汽车同步带齿形测量装置。该装置通过激光位移传感器与汽车同步带传动速度的配合,对汽车同步带齿形轮廓数据进行采集,并提出一种改进后的分割算法对采集到的齿形截面轮廓数据进行特征分割。通过对分割后齿形数据的拟合,实现了齿形轮廓曲线特征的分段重构并获得被测带齿的轮廓参数。基于激光三角法对汽车同步带齿形轮廓参数进行测量,实现了对齿形轮廓参数自动测量提高了测量效率避免了人为因素的影响,保证了测量精度,有望在汽车同步带实际生产中得到应用。

Profile parameters measurement of automotive synchronous belt based on laser triangulation method

To measure profile parameters of automotive synchronous belt, the problems include low efficiency and the influence of human factors. This paper proposes a non contact measurement scheme based on laser triangulation. The measurement device of automobile synchronous belt tooth profile is designed. The profile data acquisition of the synchronous belt is realized by the laser displacement sensor coincidence with the transmission speed of the synchronous belt. The improved segmentation algorithm is proposed to achieve feature segmentation of the collected profile data. By fitting these data after segmentation, the profile curve features are reconstructed and the profile parameters of the measured teeth are obtained. Based on the laser triangulation method, the profile parameters of synchronous belt are measured. The automatic measurement of profile parameters of automobile synchronous belt is realized, which can enhance the measurement efficiency and avoid the influence of human factors. The measurement accuracy is also ensured. It is expected that this method can be applied in the practical production of synchronous belt.
