| 重型丝杠副（最大直径300mm）的测量是业界难题。检测过程中的载荷变化是影响测量仪器精度和性能的关键因素，为此，基于中小型丝杠检测仪器的研发经验，创新仪器整体构型，对关键部件和测控系统进行优化，探索加工装配工艺，研制出重型丝杠副测量仪器，实现了重型丝杠导程误差和重型丝杠副行程误差的动态测量。经检测，在4m行程内，仪器光轴分别在距丝杠中心线50mm和150mm附近时，最大示值误差分别为0.5μm和1.3μm；对于被测丝杠副GQ100×24-P5/3028×2705，各项指标的最大值与最小值之差不超过P1级丝杠副相应允差的三分之一。检测结果表明，该重型丝杠副测量仪的测量精度能满足P1级要求。 |
| 英文摘要: |
| The measurement of heavy-duty screw pairs (maximum diameter of 300 mm) presents a significant challenge in industrial practice. Load variations during inspection constitute a key factor affecting the accuracy and performance of measurement instruments. Building upon the experience of small and medium-sized screw measurement instruments, this study optimized the overall configuration, critical components, and measurement-control systems while exploring manufacturing and assembly processes. A specialized measurement machine for heavy-duty screw pairs was successfully developed, enabling dynamic measurement of both lead error in heavy-duty screws and travel error in screw pair assemblies. Experimental results demonstrated that within a 4 m travel range, the instrument's optical axis exhibited maximum indication errors of 0.5 μm and 1.3 μm when positioned at 50 mm and 150 mm from the screw centerline, respectively. For the tested screw pair GQ100×24-P5/3028×2705, the maximum deviation between the extreme values of all measured parameters did not exceed one-third of the tolerance specified for P1-grade screw pairs. These findings confirm that the measurement accuracy of this heavy-duty screw pair machine meets P1-grade requirements. |
