摘　　要：随着先进制造技术的迅猛发展,对零件精度的要求也在不断提升,而误差检测的准确性是确保零件精度的重要前提。在三坐标测量机的工作过程中,运动轴的几何误差会显著影响检测结果。为提高检测精度和效率,设计了一款用于三坐标测量机的辅助工装,并通过对主要运动方向进行微调,实现对工件检测误差的精准补偿。以齿轮误差检测为例,根据检测系统的拓扑结构,可以推导出Houston较低序号物体阵列,建立含工装和齿轮的几何误差传递模型。研究结果为检测误差补偿提供了理论依据,也为其他多轴运动的误差传递模型提供了参考。With the rapid development of advanced manufacturing technology,the requirements for part accuracy are also constantly increasing,and the accuracy of error detection is an important prerequisite to ensure part accuracy.During the operation of a coordinate measuring machine,the geometric error of the motion axis will significantly affect the detection results.To improve detection accuracy and efficiency,an auxiliary fixture for coordinate measuring machines was designed,and precise compensation for workpiece detection errors was achieved by fine-tuning the main motion direction.Taking gear error detection as an example,and based on the topology structure of the detection system,an array of Houston objects with lower serial numbers is derived,a geometric error transmission model including fixtures and gears is established,and a compensation strategy based on fixtures is proposed.The research results provide a theoretical basis for detecting error compensation and also serve as a reference for error transmission models in other multi-axis movements.
