固体小火箭装配对其产品质量有着重要影响。目前固体小火箭装配过程中存在扭矩不能自动加载、密封圈压缩量测量繁琐、专用工装数量多的问题。为提高产品装配质量和生产效率，本文提出了固体小火箭自动装配方案。在分析现用工艺存在的问题基础上，提出了固体小火箭自动化装配的总体方案，主要解决了扭矩自动加载并自动测量密封圈压缩量和统一装夹方式减少工装数量的问题，实现装配过程关键环节的自动化。成功研制了自动化装配原理样机，实验表明，密封圈压缩量测量误差小于5%，夹持工装数量减少70%，装配效率提高了75%。
The assembly process of small solid rockets has an important influence on their quality. Currently, in the manual assembly process of small solid rockets, the tightening torque can’t be automatically loaded, measuring compressed amount of seal ring is time-consuming, and the amount of clamping device is large. In order to improve product assembly and production efficiency, an automatic assembly scheme for small solid rockets is proposed in this paper. The shortcomings of the current process are firstly analyzed and an overall scheme of automatically assembly for small solid rockets is proposed, which mainly solves the problems of automatic loading of torque and automatic measurement of seal compression and unified clamping to reduce the number of fixtures, and realizes the automation of the key links in the assembly process. A principal prototype of the automatically assembly is successfully developed, and the experiment results show that the measure error of compressed amount is within 5%, the clamping tool amount reduces about 70%, and assembly efficiency is improved about 75%.
