中文摘要: 汽车变速箱装配过程中部分零部件分装涉及到选择调整垫片的过程,垫片尺寸是否合适将直接影响变速箱整体的装配质量,为了满足新型号变速箱的数字化生产需求以及提高生产系统的工作准确性,需要将人工经验为主导的传统制造模式向轻量化、智能化的新型制造模式转化.本文结合某企业MQ250变速箱装配线的具体需求,为了提高生产现场的数字化程度以及对测量任务的管理能力,设计并实现了一套新型的变速箱零部件装配的测量系统.首先根据相对测量的原理,设计了测量模块,并分析了测量模块最优化的问题,最终通过最小二乘法实现了测量模块的优化.经过实际生产情况表明,本测量系统适应了MQ250变速箱零部件的装配需求,保证装配效率的情况下提升了整体装配质量,提高了装配生产线的数字化水平.
Abstract:The assembly of some parts during the assembly process of an automobile gearbox involves the process of selecting and adjusting gaskets. Whether the gasket size is appropriate will directly affect the overall assembly quality of the gearbox. In order to meet the production requirements of the new model gearbox and meanwhile improve the precise ability of the production system, it is necessary to transform the traditional manufacturing mode dominated by manual experience into a lightweight, intelligent new manufacturing model. In order to improve the digitization of the production site and the ability to manage the measurement tasks, the research has designed and implemented a new measurement system for gearbox assembly. The system is based on MQ250 gearbox assembly line. The research begins with the whole structure, and introduces the measurement module of the software system. First, based on the principle of relative measurement, a measurement module was designed, and the optimization problem of the measurement module was analyzed. Finally, the optimization of the measurement module was achieved by the least square method. The measurement system adapts to the assembly requirements of MQ250 gearbox components, and improves the assembly quality under the condition of ensuring assembly efficiency, and greatly improves the digital level of the assembly line while ensuring the assembly efficiency.
