1、原創(chuàng)通過(guò)答辯畢業(yè)設(shè)計(jì)說(shuō)明書(shū)論文QQ194535455凸輪軸測(cè)量?jī)x設(shè)計(jì)摘要凸輪機(jī)構(gòu)是常用機(jī)構(gòu),應(yīng)用范圍很廣。因此,對(duì)凸輪工作性能的要求就越來(lái)越高,而凸輪工作性能的好壞主要由相關(guān)的凸輪形線參數(shù)來(lái)決定。因此,目前國(guó)內(nèi)外對(duì)凸輪參數(shù)的測(cè)量?jī)x的研究和開(kāi)發(fā)也越來(lái)越廣泛和深入。凸輪軸測(cè)量?jī)x采用精密機(jī)械、光柵、微型計(jì)算機(jī)等技術(shù),為滿足汽車、摩托車發(fā)動(dòng)機(jī)凸輪軸、汽車前后橋剎車凸輪軸等檢測(cè)要求而特殊設(shè)計(jì)制造的新型測(cè)量?jī)x器,可測(cè)量凸輪軸的桃形型而誤差、桃形對(duì)定位鍵槽的相位角誤差、桃形間相位角誤差、軸徑的徑向跳動(dòng)及凸輪的速
2、度、加速度等測(cè)量項(xiàng)目。凸輪軸是工程中常用的零件,在凸輪軸的大批量生產(chǎn)中,為了保證產(chǎn)品質(zhì)量,產(chǎn)品的測(cè)量變得非常重要。凸輪軸的軸向尺寸較多并且精度較高,用傳統(tǒng)的測(cè)量方法無(wú)法保證每一件產(chǎn)品的測(cè)量精確、且容易造成測(cè)量成本過(guò)高,因此需要一臺(tái)專用的測(cè)量設(shè)備才能保證產(chǎn)品的質(zhì)量控制。所以我設(shè)計(jì)了一臺(tái)凸輪軸專用測(cè)量?jī)x。這次設(shè)計(jì)的凸輪軸測(cè)量?jī)x運(yùn)用了現(xiàn)在比較熱門的機(jī)器視覺(jué)作為測(cè)量手段,又采用了步進(jìn)電機(jī)光柵等元件,因此對(duì)信號(hào)采集,圖像處理,運(yùn)動(dòng)控制等方面有較高的要求。導(dǎo)致影響最后測(cè)量精度的因素太多,因此調(diào)試過(guò)程會(huì)比較復(fù)雜
3、。本設(shè)計(jì)中的機(jī)械結(jié)構(gòu)相對(duì)比較簡(jiǎn)單,但是關(guān)鍵零件精度要求非常高,對(duì)加工工藝以及設(shè)備要求較高,裝配精度也要求較高,因此裝配調(diào)試也比較復(fù)雜。關(guān)鍵詞:測(cè)量手段,步進(jìn)電機(jī)光柵,精度高,精密機(jī)械原創(chuàng)通過(guò)答辯畢業(yè)設(shè)計(jì)說(shuō)明書(shū)論文QQ194535455TheCamshaftMeasuringInstrumentIsDesignedAuthor:GaoXiaoHuanTutor:WangPingZhuAbstractWheelmechanismisused,theapplicationrangeisverywide.
