弹尾定心部全跳动的自动化检测技术

针对炮弹装填时炮膛的磨损和底火与击针对正问题，介绍一种炮弹弹尾定心部全跳动误差值的自动检测技术。该检测装置主要由自动升降机构、传动机构、轴向定位机构、压紧机构和检测机构等组成。将自动检测装置直接固定在弹体输送线架体上，进行弹尾定心部全跳动误差值检测时，弹体不必下线，可直接在弹体输送线上的检测工位进行，弹体的托起、轴向及径向定位和压紧、旋转和检测等所有动作均自动完成，只有百分表上的跳动值检测结果由人工读取。生产实践结果表明：该技术能提高炮弹装配生产的安全和自动化程度，减轻操作人员的劳动强度，提高生产效率。

A Technique for Automatic Detection of Total Run-Out Error of Bomb Tail Bourrelet

Aiming at the problem involved in canal wearing when bomb is loaded and aligning striker to primer,a technology is introduced for automatic detection of the total run-out error of bomb tail bourrelet.It is composed of the automatic lifting mechanism,the driving mechanism,the holddown mechanism and the measuring mechanism.The automatic-detecting equipment is directly mounted to bomb transmission product-line frame so as to checkout the total run-out error of bomb tail bourrelet at detecting workspot on bomb transmission product-line instead of bomb off-line detection.All operations such as lifting,locating in axial or radial direction,rotating and detecting can be completed automatically.Only the value of total run-out error is fetched manully via dial indicator.It shows that the technology can improve the safety and automation level in bomb production,lighten the labour intensity of operating personnel and uprate labour productivity.
