摘要:
目前人工使用千分表测量空调压缩机曲轴圆度和平面度时存在易伤工件表面、效率低和不能精确评定等 问题。针对上述问题,设计了一套基于线激光位移传感器的空调压缩机曲轴圆度和平面度非接触式测量系统。首 先,通过测量标准量棒,提出一种系统误差的标定方法;其次,基于线激光采样数据,开发了一种曲轴横截面圆度测 点的提取算法,并将系统误差用于测点补偿,实现曲轴圆度测量;接着根据曲轴平面测点间的斜率分离出轮廓线, 通过均匀下采样方法获取精简点云数据并采用最小二乘法实现曲轴平面度测量;最后,基于上述方法开展了曲轴 圆度和平面度的测量实验。实验结果表明:该测量系统的圆度测量精度<4 μm,平面度测量精度<2 μm,圆度重复 度测量误差<0.8 μm,平面度重复度测量误差<0.3 μm,满足曲轴圆度和平面度快速准确的测量需求。
Abstract:
Aiming at the problems of low efficiency and inability in accurate assessment of the roundness and flatness of air conditioning compressor crankshaft, which were measured manually with a micrometer, a set of non-con tact measurement system of roundness and flatness of air conditioning compressor crankshaft based on a line laser displacement sensor was designed. Firstly, a calibration method of systematic error was proposed by measuring a standard measuring rod. Then, based on the line laser sampling data, an extraction algorithm of crankshaft cross section roundness measurement points was developed, and the systematic error was used for the compensation of the measurement points to realize the roundness measurement of the crankshaft. After that, the contour line was separa ted according to the slope between the measurement points of the crankshaft plane, and the streamlined point cloud data were obtained by the homogeneous down sampling method, and the least square method was used to realize the flatness measurement of the crankshaft. Finally, the crankshaft roundness and flatness measurement experiments were carried out based on the above methods. The experimental results showed that the roundness measurement ac curacy of the system was less than 4 μm, the flatness measurement accuracy was less than 2 μm, the repeatability error of roundness measurement was less than 0.8 μm, and the repeatability error of flatness measurement was less than 0.3 μm, which could satisfy the requirements of fast and accurate measurement of roundness and flatness of crankshaft.
