【摘要】：陶粒砌塊是指陶粒增強(qiáng)混凝土砌塊,是一種新型墻體環(huán)保材料,有著非常廣泛的應(yīng)用市場(chǎng)。目前國(guó)內(nèi)關(guān)于陶粒增強(qiáng)混凝土砌塊的生產(chǎn)設(shè)備效率較低,生產(chǎn)工藝不足,不能滿足建筑市場(chǎng)的需求。由于剛剛加工成型的陶粒增強(qiáng)混凝土砌塊需要碼垛至指定位置進(jìn)行護(hù)養(yǎng),但是其內(nèi)部未完全凝固,容易掉角掉邊,對(duì)碼垛裝置要求較高。鑒于企業(yè)需求及現(xiàn)有碼垛機(jī)械存在的不足,設(shè)計(jì)一種專用于陶粒增強(qiáng)混凝土砌塊的碼垛機(jī)有著重要的意義。本文根據(jù)陶粒砌塊自身的特點(diǎn),設(shè)計(jì)了一種針對(duì)陶粒砌塊的夾持式碼垛機(jī)。主要內(nèi)容如下:(1)通過(guò)分析切割完成后陶粒砌塊自身的特點(diǎn)以及碼垛的要求,對(duì)其主要功能動(dòng)作進(jìn)行分解,提出多種原理結(jié)構(gòu)方案,通過(guò)分析對(duì)比,確定最終夾持式陶粒砌塊碼垛機(jī)的總體結(jié)構(gòu),并通過(guò)Solidworks軟件完成樣機(jī)三維模型的建立。(2)在三維模型建立的基礎(chǔ)上,通過(guò)ADAMS軟件對(duì)其整體和關(guān)鍵部件進(jìn)行運(yùn)動(dòng)和受力分析,通過(guò)反復(fù)調(diào)整運(yùn)動(dòng)行程和分配時(shí)間,得到各個(gè)主要關(guān)鍵部件的位移、速度、加速度以及受力分析圖等,檢驗(yàn)了夾持式陶粒砌塊碼垛機(jī)運(yùn)動(dòng)規(guī)律的準(zhǔn)確性,并為后面的力學(xué)分析、電機(jī)和液壓缸等驅(qū)動(dòng)件選型提供了理論依據(jù)。(3)根據(jù)夾持式陶粒砌塊碼垛機(jī)各關(guān)鍵部件的受力情況,通過(guò)ANSYS分析法對(duì)其進(jìn)行了靜力學(xué)分析,得到各關(guān)鍵部件的應(yīng)力和變形情況,并針對(duì)其薄弱環(huán)節(jié)進(jìn)行結(jié)構(gòu)改進(jìn),提高其性能。(4)結(jié)合夾持式陶粒砌塊碼垛機(jī)靜力學(xué)分析結(jié)果,通過(guò)使用有限元分析法和模態(tài)理論再對(duì)夾持式陶粒砌塊碼垛機(jī)進(jìn)行動(dòng)態(tài)特性分析,得出各部件的前幾階固有頻率和相應(yīng)振型,評(píng)價(jià)碼垛整體和各關(guān)鍵部件的性能,并針對(duì)其進(jìn)行結(jié)構(gòu)改進(jìn),避免共振,提高其性能。(5)通過(guò)正交試驗(yàn)分析方法對(duì)其關(guān)鍵部件進(jìn)行尺寸和結(jié)構(gòu)優(yōu)化,使其在滿足碼垛要求的條件下達(dá)到材料最少,減少制造成本,進(jìn)一步完善整機(jī)的設(shè)計(jì)。
[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.
