摘　　要：本文研制了磁性表座检测装置用于工作磁力和剩余磁力的检测,工作磁力测量范围为(0～1500) N,准确度等级为0. 1级;剩余磁力测量范围为(0～4) N,符合M2级砝码精度。该装置采用可调节行进速度和方向的直线电机作为力源,方便省力;采用高精度拉力传感器作为测试标准,校准便捷、测试精度高;采用可更换易调节开口大小的磁性表座工作磁力吸盘,可以实现不同类型的磁性表座的检测;测试拉力方向垂直于被吸附表面,更符合磁性表座出厂时的技术要求;该装置设计防护结构,保证整个检测操作过程安全可靠,可广泛应用在航天器加工装配过程中磁性表座磁力的检测。Equipment for measuring magnetic force of magnetic stand is developed. The measuring range of working magnetic force is （0 -1500）N, and the level of accuracy is 0.1. The measuring range of remaining magnetic force is （0 -4） N, and the level of accuracy is M2. In this Equipment, linear motion actuator which has adjustable speed and direction is used as power source so that it is convenient. High precision force sensor is used as measurement standard, and therefore it is accurate and convenient. Sucking disc which is easy to change and adjust opening size is used so that it can be used to measme different kinds of magnetic stand. Magnetic force direction is vertical to the adsorbed surface to make sure it is more in line with the factory index. It has protective structure to ensure the safety of measurement operation, which can be widely used in magnetic force testing of magnetic stand in the process of machining and assembling of spacecraft.
