| 为解决关键行业中直径100 ~ 300 mm的重型丝杠副的行程误差测量难题，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4 m行程内，仪器光轴分别在距丝杠中心线50 mm和150 mm附近时，最大示值误差分别为0.5 μm和1.3 μm；对于被测丝杠副样件，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1 / 3。检测结果表明：该重型丝杠副行程测量仪的测量精度能满足P1级要求。该仪器的成功研制，为促进重型丝杠副、丝杠检测领域的发展起到重要作用。 |
| 英文摘要: |
| To solve the measurement problem of stroke error for heavy?duty screw pairs with diameters of 100 ~ 300 mm in key industries, building upon the experience of small and medium?sized screw measurement instruments, this study has 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 demonstrate that within a 4 m travel range, the instrument's optical axis exhibits 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 samples, the maximum deviations between the extreme values of all measured parameters do 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 stroke measuring machine meets P1?grade requirements. The successful development of this instrument plays an important role in promoting the development of heavy?duty screw pairs and screw detection fields. |
