摘　　要：该文介绍了我院新建成的2 kN杠杆式力标准机的结构特点、工作原理、关键技术要点,该机整体结构设计合理,不同砝码自由组合实现了最大限度细化负荷级数以满足不同检定点的载荷要求,且不存在交换砝码以避免逆程现象,独立加码的驱动机构使整机结构大大简化,极大地拓展加载自由度;伺服控制系统及杠杆配置装置的良好配合,使得砝码的加卸载快速、平稳,杠杆加载配平自动化程度高。通过性能试验测试,验证了整机的计量准确性满足预期设计的计量要求。This paper introduced the structural characteristics,working principle and key technical points of 2 kN lever-type force standard machine.The overall structural design of the machine was reasonable.The free combination of different weights realized the maximum refinement of load series to meet the load requirements of different verification points,and there was no exchange of weights to avoid the reverse phenomenon.The driving mechanism of loading weights respectively has greatly simplified the structure of the machine and greatly expanded the loading degree of freedom.The good cooperation of servo control system and lever configuration device maked the weight loading and unloading fast and stable,and the lever loading and balancing automation was suitable.Through the performance test,the measurement accuracy of the whole machine was verified to meet the measurement requirements of the expected design.
