【摘要】：带式输送机在现代化的企业中得到了广泛应用,如矿山、码头、港口、交通运输等。随着经济建设的快速发展,用户对产品的性能要求越来越高,为了适应各行各业需求,带式输送机已经形成了多个系列化产品。但是目前的设计手段还是停留在二维阶段,由于二维软件设计的局限性,设计不直观、工作量大、设计过程中的错误不容易被发现。然而随着三维技术的发展,其直观、高效的设计能力完全能够满足目前企业需求,所以三维设计已经成为CAD发展的必然趋势。因此,结合一款三维软件,开发一套实用的带式输送机CAD系统具有重要意义。本课题来源于安徽盛运重工机械有限责任公司的开发项目"基于Solidworks二次开发的带式输送机设计系统"。本文结合企业实际需求,以Solidworks2012软件作为开发平台,利用VB语言结合Excel数据库,开发了一套实用的带式输送机CAD系统。课题中研究的主要内容如下:(1)首先从带式输送机的应用出发,介绍了带式输送机CAD系统发展现状和开发的必要性,然后对SolidWorks二次开发的关键技术进行研究,其中包括有对基于特征的参数化建模方法分析,选取合适的参数化建模方法;介绍了 SolidWorks宏录制技巧,能够快速获取需要的程序代码;分析了 SolidWorks二次开发API接口对象,了解其中的功能函数,从而提高了访问Solidworks的能力;通过比较数据库的访问技术,选取系统最适用的访问技术;最后论述带式输送机CAD系统的开发方法。(2)建立了带式输送机模型库、工程图库、数据库。本文中以主动半联轴器和ZL型弹性柱销齿式联轴器为例,重点分析了模型建立过程、参数表导出和属性的定义。以从动半联轴器建立的数据库为例,阐述了数据库的建立过程。(3)研究了带式输送机系统开发的方法、使用工具、系统结构、系统工作流程、系统特点等内容,让系统更加符合公司的设计要求。(4)最后通过带式输送机CAD系统的实例分析,叙述了系统的设计过程。本课题最终开发的设计系统界面简洁、设计直观、能够连接Solidworks生成生动形象的三维模型,工程图能够自动更新。该系统有利于减轻设计师的工作量,从而提高了设计效率与设计水平,符合现代化机械设计的发展要求。
[Abstract]:Belt conveyors have been widely used in modern enterprises, such as mines, wharves, ports, transportation and so on. With the rapid development of economic construction, the performance requirements of products are becoming more and more high, in order to meet the needs of various industries, The belt conveyor has formed a series of products. However, the current design method is still in the two-dimensional stage. Due to the limitations of two-dimensional software design, the design is not intuitive, and the workload is large. However, with the development of 3D technology, its intuitive and efficient design ability can completely meet the needs of enterprises, so 3D design has become an inevitable trend of CAD development. Combined with a 3D software, It is of great significance to develop a practical CAD system for belt conveyors. This subject comes from the development project of Anhui Shengyun heavy Industry Machinery Co., Ltd. "Belt conveyor design system based on Solidworks secondary development". A practical belt conveyor CAD system is developed by using VB language and Excel database based on Solidworks2012 software. The main contents of the research are as follows: (1) the application of belt conveyor is the first step. This paper introduces the development status and necessity of CAD system of belt conveyor, and then studies the key technology of SolidWorks secondary development, including the analysis of parameterized modeling method based on features, and the selection of appropriate parameterized modeling method. This paper introduces the technique of SolidWorks macro recording, which can quickly obtain the required program code, analyzes the secondary development of API interface object by SolidWorks, understands the function function in it, and improves the ability of accessing Solidworks. Finally, the model library, engineering drawing library and database of belt conveyor are established. The active semi-coupling and ZL type elastic pin gear coupling are taken as examples in this paper. The modeling process, parameter table derivation and attribute definition are analyzed emphatically. Taking the database set up by driven semi-coupling as an example, the establishment process of database is expounded. The method of developing belt conveyor system is studied and the tools are used. System structure, system workflow, system characteristics, etc., make the system more in line with the design requirements of the company. 4) finally through the belt conveyor CAD system example analysis, The design process of the system is described. The design system developed in this paper is simple in interface, intuitionistic in design, can connect Solidworks to generate vivid 3D model, and the engineering drawing can be updated automatically. The system is helpful to reduce the workload of designers. Thus, the design efficiency and design level are improved and meet the development requirements of modern mechanical design.
