火炮身管测径仪伞状定心结构设计

摘要

The inside diameter wear of the cannon barrel is one of the most important appraising standards of cannon barrel life. In this paper, a cannon barrel inside diameter gauge is designed based on the umbrella entering structure. The inside diameter gauge consists of high-precision entering mechanism and measuring mechanism and the design principle of the main components of the inside diameter gauge is introduced. The inside diameter gauge especially suitable for soldiers due to its simple structure and better operabilities. Based on analysis of the various measurement errors and comparison of the experimental data of the star-shaped inside diameter gauge and the gauge designed in this paper, the results indicated that the gauge designed in this paper has the advantages of little total error and high precision. Therefore, it can satisfy the actual requirement and very suitable for our army.%火炮身管内径磨损量是判别火炮寿命状态的主要依据之一,设计了一种基于伞状定心结构的火炮身管内径测量仪器,该仪器由高精度定心机构和测量机构构成.介绍了该仪器主要构件的设计原理,表明其具有结构简单、可操作性强,适合部队战士使用.分析了测量时可能产生的各种误差,并通过对比该仪器与星形测径仪的实验数据,结果表明本仪器具有总体误差小、精度高等优点,完全可以满足部队相关需求,是一款适合部队使用的火炮身管测径仪器.
