【摘要】：陶粒砌块是指陶粒增强混凝土砌块,是一种新型墙体环保材料,有着非常广泛的应用市场。目前国内关于陶粒增强混凝土砌块的生产设备效率较低,生产工艺不足,不能满足建筑市场的需求。由于刚刚加工成型的陶粒增强混凝土砌块需要码垛至指定位置进行护养,但是其内部未完全凝固,容易掉角掉边,对码垛装置要求较高。鉴于企业需求及现有码垛机械存在的不足,设计一种专用于陶粒增强混凝土砌块的码垛机有着重要的意义。本文根据陶粒砌块自身的特点,设计了一种针对陶粒砌块的夹持式码垛机。主要内容如下:(1)通过分析切割完成后陶粒砌块自身的特点以及码垛的要求,对其主要功能动作进行分解,提出多种原理结构方案,通过分析对比,确定最终夹持式陶粒砌块码垛机的总体结构,并通过Solidworks软件完成样机三维模型的建立。(2)在三维模型建立的基础上,通过ADAMS软件对其整体和关键部件进行运动和受力分析,通过反复调整运动行程和分配时间,得到各个主要关键部件的位移、速度、加速度以及受力分析图等,检验了夹持式陶粒砌块码垛机运动规律的准确性,并为后面的力学分析、电机和液压缸等驱动件选型提供了理论依据。(3)根据夹持式陶粒砌块码垛机各关键部件的受力情况,通过ANSYS分析法对其进行了静力学分析,得到各关键部件的应力和变形情况,并针对其薄弱环节进行结构改进,提高其性能。(4)结合夹持式陶粒砌块码垛机静力学分析结果,通过使用有限元分析法和模态理论再对夹持式陶粒砌块码垛机进行动态特性分析,得出各部件的前几阶固有频率和相应振型,评价码垛整体和各关键部件的性能,并针对其进行结构改进,避免共振,提高其性能。(5)通过正交试验分析方法对其关键部件进行尺寸和结构优化,使其在满足码垛要求的条件下达到材料最少,减少制造成本,进一步完善整机的设计。
[Abstract]:Ceramsite block is a new type of wall environmental protection material, which is a kind of ceramic reinforced concrete block, and has a very wide application market. At present, the production equipment efficiency of ceramsite reinforced concrete block is low and the production technology is insufficient, which can not meet the demand of construction market. The newly machined ceramsite reinforced concrete block needs to be palletized to the designated position for protection, but its internal solidification is not complete, so it is easy to drop the corner and drop the edge, so the palletizing device is required. In view of the demand of enterprises and the shortcomings of existing palletizing machinery, it is of great significance to design a kind of palletizing machine for ceramsite reinforced concrete blocks. According to the characteristics of ceramsite block, a clamping palletizing machine for ceramsite block is designed in this paper. The main contents are as follows: (1) by analyzing the characteristics of ceramic blocks after cutting and the requirements of palletizing, the main functional actions are decomposed, and various principle structure schemes are put forward. The overall structure of the final clamped ceramsite block palletizing machine is determined, and the 3D model of the prototype is built by Solidworks software. (2) on the basis of the 3D model establishment, the movement and force analysis of the whole and key components are carried out by ADAMS software. By adjusting the movement stroke and distributing time repeatedly, the displacement, velocity, acceleration and force analysis diagram of the main key components are obtained, and the accuracy of the motion law of the clamped ceramsite block palletizing machine is verified, which is the mechanical analysis of the behind. The selection of driving parts such as motor and hydraulic cylinder provides the theoretical basis. (3) according to the stress situation of the key parts of the clamped ceramsite block palletizing machine, the statics analysis is carried out by ANSYS analysis, and the stress and deformation of the key components are obtained. According to the structural improvement of its weak links, improve its performance. (4) combined with the statics analysis results of clamped ceramsite block palletizing machine, through the use of finite element analysis and modal theory to analyze the dynamic characteristics of clamped ceramsite block palletizing machine. The first natural frequencies and corresponding modes of each component are obtained, the performance of the whole palletizing unit and the key components is evaluated, and the structure of the palletizing unit is improved to avoid resonance. (5) optimize the size and structure of its key parts by orthogonal test analysis method, make it meet the requirements of palletizing to achieve the minimum material, reduce manufacturing costs, further improve the design of the whole machine.
