1、<p>  礦車輪對(duì)拆卸機(jī)設(shè)計(jì) </p><p>  礦車是煤礦運(yùn)輸中的主要運(yùn)輸機(jī)械,而礦車輪又是礦車的易損部件。目前很多礦廠對(duì)礦車輪的維修還靠人工來進(jìn)行,不僅工作效率低,勞動(dòng)強(qiáng)度大,而且廢品率高。隨著在我國礦業(yè)現(xiàn)代化的發(fā)展,這種原始的拆卸方法已不能滿足實(shí)際生產(chǎn)的需要,各礦廠經(jīng)常因損壞的礦車不能及時(shí)被修好而影響生產(chǎn)。因此,設(shè)計(jì)礦車輪對(duì)拆卸機(jī)具有重要的意義。設(shè)計(jì)中著重進(jìn)行了螺母拆卸機(jī)構(gòu)的設(shè)計(jì)、移動(dòng)夾持機(jī)構(gòu)

2、的設(shè)計(jì)、液壓系統(tǒng)的設(shè)計(jì),同時(shí)對(duì)卸輪鉤、傳動(dòng)齒輪、液壓系統(tǒng)等進(jìn)行了必要的校核,進(jìn)而實(shí)現(xiàn)了拆卸輪對(duì)的功能。</p><p>  二、課題研究的目的、意義</p><p>  在機(jī)械工業(yè)中,應(yīng)用機(jī)械手的意義可以概括如下:</p><p>  礦車輪對(duì)拆卸機(jī)是礦車檢修成套設(shè)備之一,是一種針對(duì)礦車輪對(duì)維修的機(jī)械設(shè)備。就現(xiàn)階段,礦車輪對(duì)的維修主要靠工人來進(jìn)行,不僅工效低,而且勞

3、動(dòng)強(qiáng)度大,維修效果差。設(shè)計(jì)一臺(tái)專用拆卸機(jī),不僅可以提高工作效率,降低企業(yè)的成本,而且可以大大地減輕工人的勞動(dòng)強(qiáng)度。</p><p>  目前,對(duì)礦車輪對(duì)拆卸機(jī)的研究幾乎是空白的,在網(wǎng)上也很難見到有關(guān)這方面研究的消息,只有中國礦業(yè)大學(xué)對(duì)其有所研究。礦車輪是煤礦運(yùn)輸機(jī)械中的易損部件,礦車輪對(duì)在使用一段時(shí)間之后必須進(jìn)行拆卸維修,以提高它的使用壽命。隨著煤礦產(chǎn)業(yè)的不斷壯大,傳統(tǒng)的手工拆卸已不能滿足生產(chǎn)的要求,對(duì)礦車輪對(duì)拆

4、卸機(jī)的設(shè)計(jì)改進(jìn)是勢(shì)在必行的。</p><p>  隨著科學(xué)技術(shù)的不斷發(fā)展,礦車輪對(duì)拆卸機(jī)的發(fā)展也會(huì)越來越快,必然會(huì)朝著高性能、高精度、高速度、高柔性化和模塊化方向發(fā)展。但最主要的發(fā)展趨勢(shì)就是采用“PC+運(yùn)動(dòng)控制器”的開放式數(shù)控系統(tǒng),它不僅具有信息處理能力強(qiáng)、開放程度高、運(yùn)動(dòng)軌跡控制精確、通用性好等特點(diǎn),而且還從很大程度上提高了現(xiàn)有加工制造的精度、柔性和應(yīng)付市場需求的能力</p><p> 

5、 三、國內(nèi)外現(xiàn)狀和發(fā)展趨勢(shì)</p><p>  礦車輪對(duì)拆卸機(jī)是礦車檢修成套設(shè)備之一,是一種針對(duì)礦車輪對(duì)維修的機(jī)械設(shè)備。就現(xiàn)階段,礦車輪對(duì)的維修主要靠工人來進(jìn)行,不僅工效低,而且勞動(dòng)強(qiáng)度大,維修效果差。設(shè)計(jì)一臺(tái)專用拆卸機(jī),不僅可以提高工作效率,降低企業(yè)的成本,而且可以大大地減輕工人的勞動(dòng)強(qiáng)度。</p><p>  目前,對(duì)礦車輪對(duì)拆卸機(jī)的研究幾乎是空白的,在網(wǎng)上也很難見到有關(guān)這方面研究的消
