【摘要】：集中润滑系统是机械设备中一种高效、清洁的润滑系统,运用成套的供油装置,对大型设备的各个润滑点按需进行供油润滑,既减少了人工投入成本,又节约了润滑资源。目前润滑系统已广泛应用在冶金、机床、车辆、生产线、风电场、工程机械等各行业,随着润滑对象的多样化,集中润滑方案层出不穷,但在集中润滑系统产品设计时,由于没有统一的零件参数标准,设计人员需要花费大量时间进行重复性图纸绘制工作,从设计到生产周期长,不利于新技术、新产品的推广。针对上述问题,本文对集中润滑系统的标准件库开发和零件的虚拟拆装进行研究,主要工作如下:(1)分析了成组技术的应用原则,利用成组技术原理对现有集中润滑系统各元件进行标准件分类。基于逆向工程的数学模型和空间拟合方法,使用全自动影像测量仪提取了集中润滑系统标准件特征参数。(2)以提取的特征参数为基础利用Access软件建立集中润滑系统模型数据库,利用VB语言完成交互界面设计。以三维设计软件SolidWorks的宏录制代码为基础,修改后完成集中润滑系统的参数化设计过程,建立集中润滑系统标准件库。(3)基于Unity3D软件对虚拟仿真关键技术进行研究,分析了虚拟拆装建立的软硬件基础和碰撞检测方法。结合数据手套和电磁式位置追踪器的工作原理,建立手部动作和空间位置参数传递程序,完成了对虚拟环境中手部模型的交互控制,为实现集中润滑系统虚拟拆装奠定基础。(4)对SolidWorks、3Dsmax、Unity3D三种软件间的数据传递方式进行研究,确定了数据传递的最优转化方法。在Unity3D环境中完成拆装设置关键程序开发,实现同一个场景下零件的拆卸和装配的转换,并进行实例测试。基于成组技术和逆向工程设计理论,应用全自动测量仪获取各零部件特征参数,以SolidWorks软件为平台,以VB为开发工具完成了集中润滑系统标准件库的二次开发。该标准件库将大幅缩短润滑产品开发周期,降低技术人员劳动强度,有利于集中润滑新产品的研制,同时也为其它机械产品提高设计效率提供了设计思路、参考和借鉴。
[Abstract]:Centralized lubrication system is an efficient and clean lubrication system in mechanical equipment. By using complete set of oil supply equipment, oil supply lubrication is carried out on every lubrication point of large equipment according to demand, which not only reduces the cost of labor input, but also saves lubrication resources. At present, lubrication system has been widely used in metallurgy, machine tool, vehicle, production line, wind farm, construction machinery and other industries. With the diversification of lubrication objects, centralized lubrication schemes emerge in endlessly, but in the product design of centralized lubrication system, Since there is no uniform standard of parts parameters, designers need to spend a lot of time on drawing repetitive drawings, from design to production cycle is long, which is not conducive to the promotion of new technology and new products. Aiming at the above problems, this paper studies the development of standard part library and virtual disassembly of parts in centralized lubrication system. The main work is as follows: 1) the application principle of group technology is analyzed. The standard parts of the existing centralized lubrication system are classified by the principle of group technology. Based on the mathematical model of reverse engineering and the method of space fitting, the characteristic parameters of standard parts of centralized lubrication system are extracted by automatic image measuring instrument. The database of centralized lubrication system model is established by using Access software based on the extracted characteristic parameters. Using VB language to complete the interface design. Based on the macro recording code of 3D design software SolidWorks, the parameterized design process of centralized lubrication system is completed after modification, and the standard part library of centralized lubrication system is established. Based on Unity3D software, the key technology of virtual simulation is studied. The hardware and software foundation and collision detection method of virtual disassembly and assembly are analyzed. Combined with the working principle of data glove and electromagnetic position tracker, the program of hand movement and spatial position parameter transmission is established, and the interactive control of hand model in virtual environment is completed. In order to realize the virtual disassembly and assembly of centralized lubrication system, the data transfer mode between SolidWorks3DsmaxandUnity3D software is studied, and the optimal data transfer method is determined. The key program of disassembly and assembly is developed in Unity3D environment, and the part disassembly and assembly transformation is realized in the same scene, and an example test is carried out. Based on group technology and reverse engineering design theory, automatic measuring instrument is used to obtain the characteristic parameters of each component. The secondary development of standard part library of centralized lubrication system is completed by using SolidWorks software as the platform and VB as the development tool. The standard part library will greatly shorten the development period of lubricating products, reduce the labor intensity of technicians, and be beneficial to the development of new centralized lubricating products. At the same time, it will also provide design ideas for other mechanical products to improve their design efficiency, reference and reference.
