【摘要】：在湿式选矿作业中,中心传动高效浓缩机是一种重要的脱水设备,主要应用于精矿浓缩和尾矿脱水。目前,中心传动高效浓缩机已形成系列化产品,包括浓缩池直径为35m、38m、40m、45m、48m、53m等型号的浓缩机。驱动机构是浓缩机耙架运转的动力来源,是影响浓缩机工作效率的重要机构。因此,把参数化设计理念应用于浓缩机的研发设计,对提高产品设计效率,缩短设计周期,推动浓缩机行业的发展具有非常重要的理论和实践意义。首先,划分模块。通过对中心传动高效浓缩机驱动机构进行结构和功能分析,采用模块化设计的方法,将系统分为驱动轴模块、电动机模块、减速机模块、轴承模块及小齿轮模块等。其次,建立数据库。根据浓缩池直径深度、最大扭矩、耙架最大线速度等初始参数,通过查阅资料和计算校核,选定驱动机构各零部件的型号及尺寸,进而建立各个模块的Access数据库。最后,三维参数化模型的建立和装配。采用基于尺寸驱动的参数化建模方法,应用ADO技术读取Access数据库,借助宏录制技术进行VB编程调用Solidworks自带的API函数,实现驱动机构各零部件参数化模型的建立。然后采用自下而上的装配设计方法,把各零部件装配成整个驱动机构。本课题以中心传动高效浓缩机驱动机构为研究对象,借助Access数据库作为后台数据支持,采用面向对象的高级编程语言VB6.0作为开发工具,对三维CAD软件Solidworks 2008进行二次开发,建立一个中心传动高效浓缩机驱动机构的三维参数化系统,实现浓缩机驱动机构的快速化设计。
[Abstract]:In wet dressing, the central drive high efficiency concentrator is an important dehydration equipment, which is mainly used in concentrate concentration and tailings dehydration. At present, the central drive high efficiency concentrator has formed a series of products, including the thickener with a diameter of 35m, 38mg, 40m, 45m, 48m, 53m, etc. The driving mechanism is the power source of the rake frame of the concentrator and the important mechanism which affects the working efficiency of the concentrator. Therefore, it is of great theoretical and practical significance to apply the idea of parametric design to the research and design of concentrator, to improve the efficiency of product design, to shorten the design cycle and to promote the development of concentrator industry. First, divide the module. By analyzing the structure and function of the drive mechanism of the high efficiency concentrator, the system is divided into driving shaft module, motor module, reducer module, bearing module and pinion module. Secondly, establish database. According to the initial parameters such as the diameter depth, maximum torque and maximum linear velocity of the rake frame, the model and size of the components of the driving mechanism are selected by consulting the data and calculating and checking, and then the Access database of each module is established. Finally, the establishment and assembly of three-dimensional parametric model. The parameterized modeling method based on dimension drive is adopted. The Access database is read by ADO technology, and the API function of Solidworks is programmed by VB with macro recording technology. The parameterized model of each component of driving mechanism is established. Then the bottom-up assembly design method is used to assemble the parts into the whole driving mechanism. In this paper, the driving mechanism of the high efficiency concentrator with central transmission is taken as the research object, the Access database is used as the backstage data support, the object-oriented high-level programming language VB6.0 is used as the development tool, and the 3D CAD software Solidworks 2008 is redeveloped. A three dimensional parameterized system for driving mechanism of high efficiency concentrator with central drive is established to realize the rapid design of driving mechanism of concentrator.
