基于双轴旋转结构的ICF靶器件精密装配实验研究

Experimental Study on Precision Assembly of ICF Target Devices Based on Double-Shaft Rotating Structure

针对惯性约束激光核聚变(ICF)靶零件夹持和装配过程中存在的重载荷与高检测分辨率之间的装配难题,该文提出了一种基于双轴旋转结构的微装配方法。首先通过分析装配目标器件(铝套筒,金腔和半腔)的特点,制定了精密装配总体结构方案。然后介绍双轴旋转装置并对相应的传感器进行标定,并进一步对集成传感器的双轴旋转装置进行角度偏转测试,可检测最小0.01°的偏转。实验表明,该双轴旋转装置能灵敏地检测到微小的偏转,并且传感器对双轴旋转具有“置零”的能力,通过该装置可在无视觉引导的情况下完成目标件的装配。

To address the assembly problem between heavy load and high detection resolution during the clamping and assembly of inertial confinement laser nuclear fusion(ICF)target parts,a micro-assembly method based on biaxial rotating structure is proposed in this paper.Firstly,by analyzing the characteristics of the assembly target devices(aluminum sleeve,gold cavity and half cavity),the overall structure scheme of precision assembly is formulated.Then,the dual-axis rotation device is introduced and the corresponding sensor is calibrated,and the angle deflection test of the dual-axis rotating device with integrated sensor is further carried out,which can detect a minimum deflection of 0.01°.The experiments show that the dual-axis rotation device can sensitively detect small deflections,and the sensor has the ability to“zero”for dual-axis rotation,through which the target assembly can be completed without visual guidance.
