LabVIEW测控下扭矩检测台的高精度自动对中

The High-precision Auto-centralizing of Torque Detection Platform Based on LabVIEW

针对检定机构及生产企业使用扭矩标准检测台检测试验物的扭矩时,不能很好地对中连接而造成上下轴不同心,影响检测台的测量精度,限制了产品质量的提高以及计量行业对产品的监督力度的问题,设计一套基于LabVIEW软件的高精度自动对中装置.装置利用Sobel算子方法,对采集的图像进行边缘检测,有效地实现自动对中,扭矩检测精度可达0.003 N·m,改善了联结同心度不高对检测结果的影响.

When testing institutions and production enterprises use the torque standard testing equipment to test objects torque,there was no good solution to measure centralizing connected factors,which caused misalignment from top to bottom,affected the measuring accuracy of the testing platform,and restricted the improvement of product quality and supervision in measurement industry.Thus,an auto-centralizing device of high-precision based on LabVIEW was designed.The device utilized Sobel operator method,detected the edge of the collected image.It can achieve an effective auto-centralizing,and the torque detection accuracy can reach 0.003 N·m,which improves the low connected concentricity on the test results.
