【摘要】：随着科学技术的进步,机电一体化技术得到了长足的发展,促使国内外对薄壁铝罐的加工能力有了较大的提升。本课题就是应用机电一体化技术,针对薄壁铝罐定长切割与翻边的加工要求,进行铝罐切口翻边一体化加工装备的设计研究。该加工装备是以一体化为设计理念,通过自动夹紧装置与自动控制技术的合理运用,实现工件的切口与翻边的机电一体化加工。本课题所做的具体工作如下： (1)对加工装备进行整体方案设计,通过对加工装备的设计与使用要求的分析,了解工件的加工特性,确定工件切割与翻边的加工方法,制定加工装备在加工过程中的传动方案,完成机床的总体布局设计。 (2)完成加工装备的整体机械结构设计,包括主轴箱、自动夹紧装置、自动上下料装置、自动切割与翻边装置、工作台等。特别对加工装备的重要部件—夹具的设计思路、结构特点及工作原理进行了详细的介绍。该夹具利用斜楔夹紧配合蝶形弹簧和铰链实现工件的自动夹紧,体现了一体化加工在加工装备中的实现。利用ANSYS软件对夹紧元件的可行性和可靠性进行有限元仿真。结果表明,当加载的力为恒力时,且保证卡爪与工件之间的接触面积不变的情况下,包角越大,对工件的夹紧变形就越小,且变形都在误差范围之内。 (3)在分析铝罐切口翻边一体化加工装备的控制功能要求的基础上,提出了基于PLC的控制系统解决方案,根据PLC的控制要求,编写了系统的顺序功能图和梯形图,既保证了工作的可靠性,又为将来的改进和扩充提供方便。 (4)最后使用了Solidworks软件对铝罐切口翻边一体化加工装备进行了三维建模、装配,并使用Animator模块对其工作过程进行了运动仿真。通过仿真检验机械系统运行的正确性,修正设计过程中存在的缺陷。
[Abstract]:With the progress of science and technology, the mechatronics technology has been developed rapidly, and the machining ability of thin-walled aluminum tank has been greatly improved at home and abroad. This subject is to apply the technology of mechatronics, aiming at the requirement of cutting and flanging of thin-walled aluminum tank, the design and research of the equipment for cutting and flanging of aluminum tank is carried out. Based on the concept of integration, the machining equipment can realize the machining of cutting and flanging of workpiece through the rational application of automatic clamping device and automatic control technology. The specific work of this topic is as follows: Through the analysis of the design and application requirements of the machining equipment, the machining characteristics of the workpiece are understood, the cutting and flanging processing method of the workpiece is determined, and the transmission scheme of the processing equipment in the process of processing is worked out. Complete the overall layout design of machine tools. 2) complete the overall mechanical structure design of processing equipment, including spindle box, automatic clamping device, automatic loading and unloading device, automatic cutting and flanging device, worktable, etc. In particular, the design idea, structural characteristics and working principle of fixture, an important part of machining equipment, are introduced in detail. The jig uses wedge-clamped sphenoid spring and hinge to realize the automatic clamping of workpiece, which embodies the realization of integrated machining in machining equipment. The feasibility and reliability of clamping elements are simulated by using ANSYS software. The results show that when the loading force is constant and the contact area between the claw and the workpiece is constant, the larger the cladding angle is, the smaller the clamping deformation of the workpiece is, and the deformation is within the error range. On the basis of analyzing the control function requirements of the integrated processing equipment for aluminum tank cutting and flanging, the control system solution based on PLC is put forward. According to the control requirements of PLC, the sequential function diagram and trapezoidal diagram of the system are compiled. It not only ensures the reliability of the work, but also provides convenience for future improvement and expansion. Finally, Solidworks software is used to model and assemble the integrated cutting and flanging equipment of aluminum tank, and the motion simulation is carried out by using Animator module. The correctness of the operation of the mechanical system is verified by simulation, and the defects in the design process are corrected.
