摘要:针对铁路货车车辆制造过程中底架下制动拉杆销钉漏铆和铆接不合格的问题,设计了一种具有空间定位功能的智能检测铆接系统,可在铆接时检测铆接质量是否合格,并依据铆枪上的电子定位标签识别出相应的铆接位置。该智能检测铆接系统包括智能铆接系统和空间定位系统两个部分,分别实时采集铆接过程中铆钉的铆接力、铆接位移和相应位置信息。现场试验结果表明,基于UWB空间定位技术的智能检测铆接系统在检测铆接质量的同时可以有效识别铆接的位置,进行铆接质量管理,防止漏铆的情况发生,以此可以建立各铆接点位置信息相关的质量检查数据库,为产品质量回溯提供查询依据,为车辆的行车安全提供保障。

Abstract:Targeting the problem of missing riveting and unqualified riveting of brake pull bar pin under the chassis in the process of freight vehicle manufacturing, an intelligent detection system for riveting with spatial positioning function is designed. This system includes two parts: the intelligent riveting system and the spatial positioning system. The riveting force, rivet displacement and corresponding position information of rivet during the riveting process are collected in real time. The test results show that the intelligent detection system for riveting based on UWB spatial positioning technology can effectively identify the riveting position while detecting the quality of riveting, carry out riveting quality management, and prevent the occurrence of missing riveting. The quality inspection database related to the location information of each riveting point could be established to provide the evidentiary basis for product quality tracing and the quality assurance for the driving safety of vehicles.
